target-i386: present virtual L3 cache info for vcpus
Some software algorithms are based on the hardware's cache info, for example,
for x86 linux kernel, when cpu1 want to wakeup a task on cpu2, cpu1 will trigger
a resched IPI and told cpu2 to do the wakeup if they don't share low level
cache. Oppositely, cpu1 will access cpu2's runqueue directly if they share llc.
The relevant linux-kernel code as bellow:
static void ttwu_queue(struct task_struct *p, int cpu)
{
struct rq *rq = cpu_rq(cpu);
......
if (... && !cpus_share_cache(smp_processor_id(), cpu)) {
......
ttwu_queue_remote(p, cpu); /* will trigger RES IPI */
return;
}
......
ttwu_do_activate(rq, p, 0); /* access target's rq directly */
......
}
In real hardware, the cpus on the same socket share L3 cache, so one won't
trigger a resched IPIs when wakeup a task on others. But QEMU doesn't present a
virtual L3 cache info for VM, then the linux guest will trigger lots of RES IPIs
under some workloads even if the virtual cpus belongs to the same virtual socket.
For KVM, there will be lots of vmexit due to guest send IPIs.
The workload is a SAP HANA's testsuite, we run it one round(about 40 minuates)
and observe the (Suse11sp3)Guest's amounts of RES IPIs which triggering during
the period:
No-L3 With-L3(applied this patch)
cpu0: 363890 44582
cpu1: 373405 43109
cpu2: 340783 43797
cpu3: 333854 43409
cpu4: 327170 40038
cpu5: 325491 39922
cpu6: 319129 42391
cpu7: 306480 41035
cpu8: 161139 32188
cpu9: 164649 31024
cpu10: 149823 30398
cpu11: 149823 32455
cpu12: 164830 35143
cpu13: 172269 35805
cpu14: 179979 33898
cpu15: 194505 32754
avg: 268963.6 40129.8
The VM's topology is "1*socket 8*cores 2*threads".
After present virtual L3 cache info for VM, the amounts of RES IPIs in guest
reduce 85%.
For KVM, vcpus send IPIs will cause vmexit which is expensive, so it can cause
severe performance degradation. We had tested the overall system performance if
vcpus actually run on sparate physical socket. With L3 cache, the performance
improves 7.2%~33.1%(avg:15.7%).

i386: Add SGX CPUID leaf FEAT_SGX_12_1_EAX
CPUID leaf 12_1_EAX is an Intel-defined feature bits leaf enumerating
the platform's SGX capabilities that may be utilized by an enclave, e.g.
whether or not an enclave can gain access to the provision key.
Currently there are six capabilities:
- INIT: set when the enclave has has been initialized by EINIT. Cannot
be set by software, i.e. forced to zero in CPUID.
- DEBUG: permits a debugger to read/write into the enclave.
- MODE64BIT: the enclave runs in 64-bit mode
- PROVISIONKEY: grants has access to the provision key
- EINITTOKENKEY: grants access to the EINIT token key, i.e. the
enclave can generate EINIT tokens
- KSS: Key Separation and Sharing enabled for the enclave.
Note that the entirety of CPUID.0x12.0x1, i.e. all registers, enumerates
the allowed ATTRIBUTES (128 bits), but only bits 31:0 are directly
exposed to the user (via FEAT_12_1_EAX). Bits 63:32 are currently all
reserved and bits 127:64 correspond to the allowed XSAVE Feature Request
Mask, which is calculated based on other CPU features, e.g. XSAVE, MPX,
AVX, etc... and is not exposed to the user.

i386: Add SGX CPUID leaf FEAT_SGX_12_1_EAX
CPUID leaf 12_1_EAX is an Intel-defined feature bits leaf enumerating
the platform's SGX capabilities that may be utilized by an enclave, e.g.
whether or not an enclave can gain access to the provision key.
Currently there are six capabilities:
- INIT: set when the enclave has has been initialized by EINIT. Cannot
be set by software, i.e. forced to zero in CPUID.
- DEBUG: permits a debugger to read/write into the enclave.
- MODE64BIT: the enclave runs in 64-bit mode
- PROVISIONKEY: grants has access to the provision key
- EINITTOKENKEY: grants access to the EINIT token key, i.e. the
enclave can generate EINIT tokens
- KSS: Key Separation and Sharing enabled for the enclave.
Note that the entirety of CPUID.0x12.0x1, i.e. all registers, enumerates
the allowed ATTRIBUTES (128 bits), but only bits 31:0 are directly
exposed to the user (via FEAT_12_1_EAX). Bits 63:32 are currently all
reserved and bits 127:64 correspond to the allowed XSAVE Feature Request
Mask, which is calculated based on other CPU features, e.g. XSAVE, MPX,
AVX, etc... and is not exposed to the user.

target/i386: add VMX features to named CPU models
This allows using "-cpu Haswell,+vmx", which we did not really want to
support in QEMU but was produced by Libvirt when using the "host-model"
CPU model. Without this patch, no VMX feature is _actually_ supported
(only the basic instruction set extensions are) and KVM fails to load
in the guest.
This was produced from the output of scripts/kvm/vmxcap using the following
very ugly Python script:

Note that the script has a bug in that some keys apply to both VM entry

"load IA32_PAT". Those have to be fixed by hand.

target/i386: add VMX features to named CPU models
This allows using "-cpu Haswell,+vmx", which we did not really want to
support in QEMU but was produced by Libvirt when using the "host-model"
CPU model. Without this patch, no VMX feature is _actually_ supported
(only the basic instruction set extensions are) and KVM fails to load
in the guest.
This was produced from the output of scripts/kvm/vmxcap using the following
very ugly Python script:

target/i386: add VMX features to named CPU models
This allows using "-cpu Haswell,+vmx", which we did not really want to
support in QEMU but was produced by Libvirt when using the "host-model"
CPU model. Without this patch, no VMX feature is _actually_ supported
(only the basic instruction set extensions are) and KVM fails to load
in the guest.
This was produced from the output of scripts/kvm/vmxcap using the following
very ugly Python script:

Note that the script has a bug in that some keys apply to both VM entry
and VM exit controls ("load IA32_PERF_GLOBAL_CTRL", "load IA32_EFER",
"load IA32_PAT". Those have to be fixed by hand.

target/i386: add VMX features to named CPU models
This allows using "-cpu Haswell,+vmx", which we did not really want to
support in QEMU but was produced by Libvirt when using the "host-model"
CPU model. Without this patch, no VMX feature is _actually_ supported
(only the basic instruction set extensions are) and KVM fails to load
in the guest.
This was produced from the output of scripts/kvm/vmxcap using the following
very ugly Python script:

target/i386: add VMX features to named CPU models
This allows using "-cpu Haswell,+vmx", which we did not really want to
support in QEMU but was produced by Libvirt when using the "host-model"
CPU model. Without this patch, no VMX feature is _actually_ supported
(only the basic instruction set extensions are) and KVM fails to load
in the guest.
This was produced from the output of scripts/kvm/vmxcap using the following
very ugly Python script:

Note that the script has a bug in that some keys apply to both VM entry
and VM exit controls ("load IA32_PERF_GLOBAL_CTRL", "load IA32_EFER",
"load IA32_PAT". Those have to be fixed by hand.

target/i386: add VMX features to named CPU models
This allows using "-cpu Haswell,+vmx", which we did not really want to
support in QEMU but was produced by Libvirt when using the "host-model"
CPU model. Without this patch, no VMX feature is _actually_ supported
(only the basic instruction set extensions are) and KVM fails to load
in the guest.
This was produced from the output of scripts/kvm/vmxcap using the following
very ugly Python script:

Note that the script has a bug in that some keys apply to both VM entry
and VM exit controls ("load IA32_PERF_GLOBAL_CTRL", "load IA32_EFER",
"load IA32_PAT". Those have to be fixed by hand.

target/i386: add VMX features to named CPU models
This allows using "-cpu Haswell,+vmx", which we did not really want to
support in QEMU but was produced by Libvirt when using the "host-model"
CPU model. Without this patch, no VMX feature is _actually_ supported
(only the basic instruction set extensions are) and KVM fails to load
in the guest.
This was produced from the output of scripts/kvm/vmxcap using the following
very ugly Python script:

target/i386: add VMX features to named CPU models
This allows using "-cpu Haswell,+vmx", which we did not really want to
support in QEMU but was produced by Libvirt when using the "host-model"
CPU model. Without this patch, no VMX feature is _actually_ supported
(only the basic instruction set extensions are) and KVM fails to load
in the guest.
This was produced from the output of scripts/kvm/vmxcap using the following
very ugly Python script:

Note that the script has a bug in that some keys apply to both VM entry
and VM exit controls ("load IA32_PERF_GLOBAL_CTRL", "load IA32_EFER",
"load IA32_PAT". Those have to be fixed by hand.

target/i386: add VMX features to named CPU models
This allows using "-cpu Haswell,+vmx", which we did not really want to
support in QEMU but was produced by Libvirt when using the "host-model"
CPU model. Without this patch, no VMX feature is _actually_ supported
(only the basic instruction set extensions are) and KVM fails to load
in the guest.
This was produced from the output of scripts/kvm/vmxcap using the following
very ugly Python script:

Note that the script has a bug in that some keys apply to both VM entry

"load IA32_PAT". Those have to be fixed by hand.

target/i386: add VMX features to named CPU models
This allows using "-cpu Haswell,+vmx", which we did not really want to
support in QEMU but was produced by Libvirt when using the "host-model"
CPU model. Without this patch, no VMX feature is _actually_ supported
(only the basic instruction set extensions are) and KVM fails to load
in the guest.
This was produced from the output of scripts/kvm/vmxcap using the following
very ugly Python script:

Note that the script has a bug in that some keys apply to both VM entry
and VM exit controls ("load IA32_PERF_GLOBAL_CTRL", "load IA32_EFER",
"load IA32_PAT". Those have to be fixed by hand.

target/i386: add VMX features to named CPU models
This allows using "-cpu Haswell,+vmx", which we did not really want to
support in QEMU but was produced by Libvirt when using the "host-model"
CPU model. Without this patch, no VMX feature is _actually_ supported
(only the basic instruction set extensions are) and KVM fails to load
in the guest.
This was produced from the output of scripts/kvm/vmxcap using the following
very ugly Python script:

Note that the script has a bug in that some keys apply to both VM entry
and VM exit controls ("load IA32_PERF_GLOBAL_CTRL", "load IA32_EFER",
"load IA32_PAT". Those have to be fixed by hand.

target/i386: add VMX features to named CPU models
This allows using "-cpu Haswell,+vmx", which we did not really want to
support in QEMU but was produced by Libvirt when using the "host-model"
CPU model. Without this patch, no VMX feature is _actually_ supported
(only the basic instruction set extensions are) and KVM fails to load
in the guest.
This was produced from the output of scripts/kvm/vmxcap using the following
very ugly Python script:

Note that the script has a bug in that some keys apply to both VM entry
and VM exit controls ("load IA32_PERF_GLOBAL_CTRL", "load IA32_EFER",
"load IA32_PAT". Those have to be fixed by hand.

target/i386: Add the 'model-id' for Skylake -v3 CPU models
This fixes a confusion in the help output. (Although, if you squint
long enough at the '-cpu help' output, you _do_ notice that
"Skylake-Client-noTSX-IBRS" is an alias of "Skylake-Client-v3";
similarly for Skylake-Server-v3.)
Without this patch:
$ qemu-system-x86 -cpu help
...
x86 Skylake-Client-v1 Intel Core Processor (Skylake)
x86 Skylake-Client-v2 Intel Core Processor (Skylake, IBRS)
x86 Skylake-Client-v3 Intel Core Processor (Skylake, IBRS)
...
x86 Skylake-Server-v1 Intel Xeon Processor (Skylake)
x86 Skylake-Server-v2 Intel Xeon Processor (Skylake, IBRS)
x86 Skylake-Server-v3 Intel Xeon Processor (Skylake, IBRS)
...
With this patch:
$ ./qemu-system-x86 -cpu help

target/i386: add VMX features to named CPU models
This allows using "-cpu Haswell,+vmx", which we did not really want to
support in QEMU but was produced by Libvirt when using the "host-model"
CPU model. Without this patch, no VMX feature is _actually_ supported
(only the basic instruction set extensions are) and KVM fails to load
in the guest.
This was produced from the output of scripts/kvm/vmxcap using the following
very ugly Python script:

Note that the script has a bug in that some keys apply to both VM entry
and VM exit controls ("load IA32_PERF_GLOBAL_CTRL", "load IA32_EFER",
"load IA32_PAT". Those have to be fixed by hand.

target/i386: Add the 'model-id' for Skylake -v3 CPU models
This fixes a confusion in the help output. (Although, if you squint
long enough at the '-cpu help' output, you _do_ notice that
"Skylake-Client-noTSX-IBRS" is an alias of "Skylake-Client-v3";
similarly for Skylake-Server-v3.)
Without this patch:
$ qemu-system-x86 -cpu help
...
x86 Skylake-Client-v1 Intel Core Processor (Skylake)
x86 Skylake-Client-v2 Intel Core Processor (Skylake, IBRS)
x86 Skylake-Client-v3 Intel Core Processor (Skylake, IBRS)
...
x86 Skylake-Server-v1 Intel Xeon Processor (Skylake)
x86 Skylake-Server-v2 Intel Xeon Processor (Skylake, IBRS)
x86 Skylake-Server-v3 Intel Xeon Processor (Skylake, IBRS)
...
With this patch:
$ ./qemu-system-x86 -cpu help
...
x86 Skylake-Client-v1 Intel Core Processor (Skylake)
x86 Skylake-Client-v2 Intel Core Processor (Skylake, IBRS)

target/i386: add VMX features to named CPU models
This allows using "-cpu Haswell,+vmx", which we did not really want to
support in QEMU but was produced by Libvirt when using the "host-model"
CPU model. Without this patch, no VMX feature is _actually_ supported
(only the basic instruction set extensions are) and KVM fails to load
in the guest.
This was produced from the output of scripts/kvm/vmxcap using the following
very ugly Python script:

Note that the script has a bug in that some keys apply to both VM entry
and VM exit controls ("load IA32_PERF_GLOBAL_CTRL", "load IA32_EFER",
"load IA32_PAT". Those have to be fixed by hand.

i386: Add new CPU model Icelake-{Server,Client}
New CPU models mostly inherit features from ancestor Skylake, while addin new
features: UMIP, New Instructions ( PCONIFIG (server only), WBNOINVD,
AVX512_VBMI2, GFNI, AVX512_VNNI, VPCLMULQDQ, VAES, AVX512_BITALG),
Intel PT and 5-level paging (Server only). As well as
IA32_PRED_CMD, SSBD support for speculative execution
side channel mitigations.
Note:
For 5-level paging, Guest physical address width can be configured, with
parameter "phys-bits". Unless explicitly specified, we still use its default
value, even for Icelake-Server cpu model.
At present, hold on expose IA32_ARCH_CAPABILITIES to guest, as 1) This MSR
actually presents more than 1 'feature', maintainers are considering expanding current
features presentation of only CPUIDs to MSR bits; 2) a reasonable default value
for MSR_IA32_ARCH_CAPABILITIES needs to settled first. These 2 are actully
beyond Icelake CPU model itself but fundamental. So split these work apart
and do it later.

target/i386: add VMX features to named CPU models
This allows using "-cpu Haswell,+vmx", which we did not really want to
support in QEMU but was produced by Libvirt when using the "host-model"
CPU model. Without this patch, no VMX feature is _actually_ supported
(only the basic instruction set extensions are) and KVM fails to load
in the guest.
This was produced from the output of scripts/kvm/vmxcap using the following
very ugly Python script:

Note that the script has a bug in that some keys apply to both VM entry

"load IA32_PAT". Those have to be fixed by hand.

i386: Add new CPU model Icelake-{Server,Client}
New CPU models mostly inherit features from ancestor Skylake, while addin new
features: UMIP, New Instructions ( PCONIFIG (server only), WBNOINVD,
AVX512_VBMI2, GFNI, AVX512_VNNI, VPCLMULQDQ, VAES, AVX512_BITALG),
Intel PT and 5-level paging (Server only). As well as
IA32_PRED_CMD, SSBD support for speculative execution
side channel mitigations.
Note:
For 5-level paging, Guest physical address width can be configured, with
parameter "phys-bits". Unless explicitly specified, we still use its default
value, even for Icelake-Server cpu model.
At present, hold on expose IA32_ARCH_CAPABILITIES to guest, as 1) This MSR
actually presents more than 1 'feature', maintainers are considering expanding current
features presentation of only CPUIDs to MSR bits; 2) a reasonable default value
for MSR_IA32_ARCH_CAPABILITIES needs to settled first. These 2 are actully
beyond Icelake CPU model itself but fundamental. So split these work apart
and do it later.

target/i386: add VMX features to named CPU models
This allows using "-cpu Haswell,+vmx", which we did not really want to
support in QEMU but was produced by Libvirt when using the "host-model"
CPU model. Without this patch, no VMX feature is _actually_ supported
(only the basic instruction set extensions are) and KVM fails to load
in the guest.
This was produced from the output of scripts/kvm/vmxcap using the following
very ugly Python script:

Note that the script has a bug in that some keys apply to both VM entry
and VM exit controls ("load IA32_PERF_GLOBAL_CTRL", "load IA32_EFER",
"load IA32_PAT". Those have to be fixed by hand.

target/i386: add VMX features to named CPU models
This allows using "-cpu Haswell,+vmx", which we did not really want to
support in QEMU but was produced by Libvirt when using the "host-model"
CPU model. Without this patch, no VMX feature is _actually_ supported
(only the basic instruction set extensions are) and KVM fails to load
in the guest.
This was produced from the output of scripts/kvm/vmxcap using the following
very ugly Python script:

Note that the script has a bug in that some keys apply to both VM entry
and VM exit controls ("load IA32_PERF_GLOBAL_CTRL", "load IA32_EFER",
"load IA32_PAT". Those have to be fixed by hand.

i386: Resolve CPU models to v1 by default
When using `query-cpu-definitions` using `-machine none`,
QEMU is resolving all CPU models to their latest versions. The
actual CPU model version being used by another machine type (e.g.
`pc-q35-4.0`) might be different.
In theory, this was OK because the correct CPU model
version is returned when using the correct `-machine` argument.
Except that in practice, this breaks libvirt expectations:
libvirt always use `-machine none` when checking if a CPU model
is runnable, because runnability is not expected to be affected
when the machine type is changed.
For example, when running on a Haswell host without TSX,
Haswell-v4 is runnable, but Haswell-v1 is not. On those hosts,
`query-cpu-definitions` says Haswell is runnable if using
`-machine none`, but Haswell is actually not runnable using any
of the `pc-*` machine types (because they resolve Haswell to
Haswell-v1). In other words, we're breaking the "runnability
guarantee" we promised to not break for a few releases (see
qemu-deprecated.texi).
To address this issue, change the default CPU model version to v1
on all machine types, so we make `query-cpu-definitions` output
when using `-machine none` match the results when using `pc-*`.
This will change in the future (the plan is to always return the
latest CPU model version if using `-machine none`), but only
after giving libvirt the opportunity to adapt.

qom: Swap 'name' next to visitor in ObjectPropertyAccessor
Similar to the previous patch, it's nice to have all functions
in the tree that involve a visitor and a name for conversion to
or from QAPI to consistently stick the 'name' parameter next
to the Visitor parameter.
Done by manually changing include/qom/object.h and qom/object.c,
then running this Coccinelle script and touching up the fallout
(Coccinelle insisted on adding some trailing whitespace).

qapi: Swap visit_* arguments for consistent 'name' placement
JSON uses "name":value, but many of our visitor interfaces were
called with visit_type_FOO(v, &value, name, errp). This can be
a bit confusing to have to mentally swap the parameter order to
match JSON order. It's particularly bad for visit_start_struct(),
where the 'name' parameter is smack in the middle of the
otherwise-related group of 'obj, kind, size' parameters! It's
time to do a global swap of the parameter ordering, so that the
'name' parameter is always immediately after the Visitor argument.
Additional reason in favor of the swap: the existing include/qjson.h
prefers listing 'name' first in json_prop_*(), and I have plans to
unify that file with the qapi visitors; listing 'name' first in
qapi will minimize churn to the (admittedly few) qjson.h clients.
Later patches will then fix docs, object.h, visitor-impl.h, and
those clients to match.
Done by first patching scripts/qapi*.py by hand to make generated
files do what I want, then by running the following Coccinelle
script to affect the rest of the code base:
$ spatch --sp-file script `git grep -l '\bvisit_' -- '**/*.[ch]'`
I then had to apply some touchups (Coccinelle insisted on TAB
indentation in visitor.h, and botched the signature of
visit_type_enum() by rewriting 'const char *const strings[]' to
the syntactically invalid 'const char*const[] strings'). The
movement of parameters is sufficient to provoke compiler errors
if any callers were missed.

qom: Swap 'name' next to visitor in ObjectPropertyAccessor
Similar to the previous patch, it's nice to have all functions

Done by manually changing include/qom/object.h and qom/object.c,

qapi: Swap visit_* arguments for consistent 'name' placement
JSON uses "name":value, but many of our visitor interfaces were
called with visit_type_FOO(v, &value, name, errp). This can be
a bit confusing to have to mentally swap the parameter order to
match JSON order. It's particularly bad for visit_start_struct(),
where the 'name' parameter is smack in the middle of the
otherwise-related group of 'obj, kind, size' parameters! It's
time to do a global swap of the parameter ordering, so that the
'name' parameter is always immediately after the Visitor argument.
Additional reason in favor of the swap: the existing include/qjson.h
prefers listing 'name' first in json_prop_*(), and I have plans to
unify that file with the qapi visitors; listing 'name' first in
qapi will minimize churn to the (admittedly few) qjson.h clients.
Later patches will then fix docs, object.h, visitor-impl.h, and
those clients to match.
Done by first patching scripts/qapi*.py by hand to make generated
files do what I want, then by running the following Coccinelle
script to affect the rest of the code base:
$ spatch --sp-file script `git grep -l '\bvisit_' -- '**/*.[ch]'`
I then had to apply some touchups (Coccinelle insisted on TAB
indentation in visitor.h, and botched the signature of
visit_type_enum() by rewriting 'const char *const strings[]' to
the syntactically invalid 'const char*const[] strings'). The
movement of parameters is sufficient to provoke compiler errors
if any callers were missed.

Not exactly elegant, I'm afraid.
The "when != lbl:" is necessary to avoid transforming
if (fun(args, &err)) {
goto out
}
...
out:
error_propagate(errp, err);
even though other paths to label out still need the error_propagate().
For an actual example, see sclp_realize().
Without the "when strict", Coccinelle transforms vfio_msix_setup(),
incorrectly. I don't know what exactly "when strict" does, only that
it helps here.
The match of return is narrower than what I want, but I can't figure
out how to express "return where the operand doesn't use @err". For
an example where it's too narrow, see vfio_intx_enable().
Silently fails to convert hw/arm/armsse.c, because Coccinelle gets
confused by ARMSSE being used both as typedef and function-like macro

Line breaks tidied up manually. One nested declaration of @local_err

qom: Swap 'name' next to visitor in ObjectPropertyAccessor
Similar to the previous patch, it's nice to have all functions
in the tree that involve a visitor and a name for conversion to
or from QAPI to consistently stick the 'name' parameter next
to the Visitor parameter.
Done by manually changing include/qom/object.h and qom/object.c,
then running this Coccinelle script and touching up the fallout
(Coccinelle insisted on adding some trailing whitespace).

qapi: Swap visit_* arguments for consistent 'name' placement
JSON uses "name":value, but many of our visitor interfaces were
called with visit_type_FOO(v, &value, name, errp). This can be
a bit confusing to have to mentally swap the parameter order to
match JSON order. It's particularly bad for visit_start_struct(),
where the 'name' parameter is smack in the middle of the
otherwise-related group of 'obj, kind, size' parameters! It's
time to do a global swap of the parameter ordering, so that the
'name' parameter is always immediately after the Visitor argument.
Additional reason in favor of the swap: the existing include/qjson.h
prefers listing 'name' first in json_prop_*(), and I have plans to
unify that file with the qapi visitors; listing 'name' first in
qapi will minimize churn to the (admittedly few) qjson.h clients.
Later patches will then fix docs, object.h, visitor-impl.h, and
those clients to match.
Done by first patching scripts/qapi*.py by hand to make generated
files do what I want, then by running the following Coccinelle
script to affect the rest of the code base:
$ spatch --sp-file script `git grep -l '\bvisit_' -- '**/*.[ch]'`
I then had to apply some touchups (Coccinelle insisted on TAB
indentation in visitor.h, and botched the signature of
visit_type_enum() by rewriting 'const char *const strings[]' to
the syntactically invalid 'const char*const[] strings'). The
movement of parameters is sufficient to provoke compiler errors
if any callers were missed.

i386: improve sorting of CPU model names
The current list of CPU model names output by "-cpu help" is sorted
alphabetically based on the internal QOM class name. The text that is
displayed, however, uses the CPU model name, which is equivalent to the
QOM class name, minus a suffix. Unfortunately that suffix has an effect
on the sort ordering, for example, causing the various Broadwell
variants to appear reversed:
x86 486
x86 Broadwell-IBRS Intel Core Processor (Broadwell, IBRS)
x86 Broadwell-noTSX-IBRS Intel Core Processor (Broadwell, no TSX, IBRS
x86 Broadwell-noTSX Intel Core Processor (Broadwell, no TSX)
x86 Broadwell Intel Core Processor (Broadwell)
x86 Conroe Intel Celeron_4x0 (Conroe/Merom Class Core 2)
By sorting on the actual CPU model name text that is displayed, the
result is
x86 486
x86 Broadwell Intel Core Processor (Broadwell)
x86 Broadwell-IBRS Intel Core Processor (Broadwell, IBRS)
x86 Broadwell-noTSX Intel Core Processor (Broadwell, no TSX)
x86 Broadwell-noTSX-IBRS Intel Core Processor (Broadwell, no TSX, IBRS)
x86 Conroe Intel Celeron_4x0 (Conroe/Merom Class Core 2)
This requires extra string allocations during sorting, but this is not a
concern given the usage scenario and the number of CPU models that exist.

i386: Define static "base" CPU model
The query-cpu-model-expand QMP command needs at least one static
model, to allow the "static" expansion mode to be implemented.
Instead of defining static versions of every CPU model, define a
"base" CPU model that has absolutely no feature flag enabled.
Despite having no CPUID data set at all, "-cpu base" is even a
functional CPU:
* It can boot a Slackware Linux 1.01 image with a Linux 0.99.12
kernel[1].
* It is even possible to boot[2] a modern Fedora x86_64 guest by
manually enabling the following CPU features:
-cpu base,+lm,+msr,+pae,+fpu,+cx8,+cmov,+sse,+sse2,+fxsr
[1] http://www.qemu-advent-calendar.org/2014/#day-1

i386: do not call cpudef-only models functions for max, host, base
Some cpu properties have to be set only for cpu models in builtin_x86_defs,
registered with x86_register_cpu_model_type, and not for
cpu models "base", "max", and the subclass "host".
These properties are the ones set by function x86_cpu_apply_props,
(also including kvm_default_props, tcg_default_props),
and the "vendor" property for the KVM and HVF accelerators.
After recent refactoring of cpu, which also affected these properties,
they were instead set unconditionally for all x86 cpus.
This has been detected as a bug with Nested on AMD with cpu "host",
as svm was not turned on by default, due to the wrongful setting of
kvm_default_props via x86_cpu_apply_props, which set svm to "off".
Rectify the bug introduced in commit "i386: split cpu accelerators"
and document the functions that are builtin_x86_defs-only.

i386: do not call cpudef-only models functions for max, host, base
Some cpu properties have to be set only for cpu models in builtin_x86_defs,
registered with x86_register_cpu_model_type, and not for
cpu models "base", "max", and the subclass "host".
These properties are the ones set by function x86_cpu_apply_props,
(also including kvm_default_props, tcg_default_props),
and the "vendor" property for the KVM and HVF accelerators.
After recent refactoring of cpu, which also affected these properties,
they were instead set unconditionally for all x86 cpus.
This has been detected as a bug with Nested on AMD with cpu "host",
as svm was not turned on by default, due to the wrongful setting of
kvm_default_props via x86_cpu_apply_props, which set svm to "off".
Rectify the bug introduced in commit "i386: split cpu accelerators"
and document the functions that are builtin_x86_defs-only.

target-i386: present virtual L3 cache info for vcpus
Some software algorithms are based on the hardware's cache info, for example,
for x86 linux kernel, when cpu1 want to wakeup a task on cpu2, cpu1 will trigger
a resched IPI and told cpu2 to do the wakeup if they don't share low level
cache. Oppositely, cpu1 will access cpu2's runqueue directly if they share llc.
The relevant linux-kernel code as bellow:
static void ttwu_queue(struct task_struct *p, int cpu)
{
struct rq *rq = cpu_rq(cpu);
......
if (... && !cpus_share_cache(smp_processor_id(), cpu)) {
......
ttwu_queue_remote(p, cpu); /* will trigger RES IPI */
return;
}
......
ttwu_do_activate(rq, p, 0); /* access target's rq directly */
......
}
In real hardware, the cpus on the same socket share L3 cache, so one won't
trigger a resched IPIs when wakeup a task on others. But QEMU doesn't present a
virtual L3 cache info for VM, then the linux guest will trigger lots of RES IPIs
under some workloads even if the virtual cpus belongs to the same virtual socket.
For KVM, there will be lots of vmexit due to guest send IPIs.
The workload is a SAP HANA's testsuite, we run it one round(about 40 minuates)
and observe the (Suse11sp3)Guest's amounts of RES IPIs which triggering during
the period:

x86: cpu: fixup number of addressable IDs for logical processors sharing cache
When QEMU is started with '-cpu host,host-cache-info=on', it will
passthrough host's number of logical processors sharing cache and
number of processor cores in the physical package. QEMU already
fixes up the later to correctly reflect number of configured cores
for VM, however number of logical processors sharing cache is still
comes from host CPU, which confuses guest started with:
-machine q35,accel=kvm \
-cpu host,host-cache-info=on,l3-cache=off \
-smp 20,sockets=2,dies=1,cores=10,threads=1 \
-numa node,nodeid=0,memdev=ram-node0 \
-numa node,nodeid=1,memdev=ram-node1 \
-numa cpu,socket-id=0,node-id=0 \
-numa cpu,socket-id=1,node-id=1
on 2 socket Xeon 4210R host with 10 cores per socket
with CPUID[04H]:
...
--- cache 3 ---
cache type = unified cache (3)
cache level = 0x3 (3)
self-initializing cache level = true
fully associative cache = false
maximum IDs for CPUs sharing cache = 0x1f (31)
maximum IDs for cores in pkg = 0xf (15)
...
that doesn't match number of logical processors VM was
configured with and as result RHEL 9.0 guest complains:
sched: CPU #10's llc-sibling CPU #0 is not on the same node! [node: 1 != 0]. Ignoring dependency.
WARNING: CPU: 10 PID: 0 at arch/x86/kernel/smpboot.c:421 topology_sane.isra.0+0x67/0x80

Fix it by capping max number of logical processors to vcpus/socket

Expose CPUID leaf 7 only for -cpu host
Changes v2 -> v3;
- Check for kvm_enabled() before setting cpuid_7_0_ebx_features
Changes v1 -> v2:
- Use kvm_arch_get_supported_cpuid() instead of host_cpuid() on
cpu_x86_fill_host().
We should use GET_SUPPORTED_CPUID for all bits on "-cpu host"
eventually, but I am not changing all the other CPUID leaves because
we may not be able to test such an intrusive change in time for 1.1.
Description of the bug:
Since QEMU 0.15, the CPUID information on CPUID[EAX=7,ECX=0] is being
returned unfiltered to the guest, directly from the GET_SUPPORTED_CPUID
return value.
The problem is that this makes the resulting CPU feature flags
unpredictable and dependent on the host CPU and kernel version. This
breaks live-migration badly if migrating from a host CPU that supports
some features on that CPUID leaf (running a recent kernel) to a kernel
or host CPU that doesn't support it.
Migration also is incorrect (the virtual CPU changes under the guest's
feet) if you migrate in the opposite direction (from an old CPU/kernel
to a new CPU/kernel), but with less serious consequences (guests
normally query CPUID information only once on boot).
Fortunately, the bug affects only users using cpudefs with level >= 7.
The right behavior should be to explicitly enable those features on
[cpudef] config sections or on the "-cpu" command-line arguments. Right
now there is no predefined CPU model on QEMU that has those features:
the latest Intel model we have is Sandy Bridge.
I would like to get this fixed on 1.1, so I am submitting this patch,
that enables those features only if "-cpu host" is being used (as we
don't have any pre-defined CPU model that actually have those features).
After 1.1 is released, we can make those features properly configurable
on [cpudef] and -cpu configuration.
One problem is: with this patch, users with the following setup:
- Running QEMU 1.0;
- Using a cpudef having level >= 7;
- Running a kernel that supports the features on CPUID leaf 7; and
- Running on a CPU that supports some features on CPUID leaf 7
won't be able to live-migrate to QEMU 1.1. But for these users
live-migration is already broken (they can't live-migrate to hosts with
older CPUs or older kernels, already), I don't see how to avoid this
problem.

cpu: Use DeviceClass reset instead of a special CPUClass reset
The CPUClass has a 'reset' method. This is a legacy from when
TYPE_CPU used not to inherit from TYPE_DEVICE. We don't need it any
more, as we can simply use the TYPE_DEVICE reset. The 'cpu_reset()'
function is kept as the API which most places use to reset a CPU; it
is now a wrapper which calls device_cold_reset() and then the
tracepoint function.
This change should not cause CPU objects to be reset more often
than they are at the moment, because:
* nobody is directly calling device_cold_reset() or
qdev_reset_all() on CPU objects
* no CPU object is on a qbus, so they will not be reset either
by somebody calling qbus_reset_all()/bus_cold_reset(), or
by the main "reset sysbus and everything in the qbus tree"
reset that most devices are reset by
Note that this does not change the need for each machine or whatever
to use qemu_register_reset() to arrange to call cpu_reset() -- that
is necessary because CPU objects are not on any qbus, so they don't
get reset when the qbus tree rooted at the sysbus bus is reset, and
this isn't being changed here.
All the changes to the files under target/ were made using the
included Coccinelle script, except:
(1) the deletion of the now-inaccurate and not terribly useful
"CPUClass::reset" comments was done with a perl one-liner afterwards:
perl -n -i -e '/ CPUClass::reset/ or print' target/*/*.c
(2) this bit of the s390 change was done by hand, because the
Coccinelle script is not sophisticated enough to handle the
parent_reset call being inside another function:

/***** Steps involved on loading and filtering CPUID data
|
|
|
|
*
|
|
|
|
* When initializing and realizing a CPU object, the steps
|
|
|
|
* involved in setting up CPUID data are:
|
|
|
|
*
|
|
|
|
* 1) Loading CPU model definition (X86CPUDefinition). This is
|
2019-06-28 03:28:39 +03:00
|
|
|
* implemented by x86_cpu_load_model() and should be completely
|
2017-01-17 00:11:21 +03:00
|
|
|
* transparent, as it is done automatically by instance_init.
|
|
|
|
* No code should need to look at X86CPUDefinition structs
|
|
|
|
* outside instance_init.
|
|
|
|
*
|
|
|
|
* 2) CPU expansion. This is done by realize before CPUID
|
|
|
|
* filtering, and will make sure host/accelerator data is
|
|
|
|
* loaded for CPU models that depend on host capabilities
|
|
|
|
* (e.g. "host"). Done by x86_cpu_expand_features().
|
|
|
|
*
|
|
|
|
* 3) CPUID filtering. This initializes extra data related to
|
|
|
|
* CPUID, and checks if the host supports all capabilities
|
|
|
|
* required by the CPU. Runnability of a CPU model is
|
|
|
|
* determined at this step. Done by x86_cpu_filter_features().
|
|
|
|
*
|
|
|
|
* Some operations don't require all steps to be performed.
|
|
|
|
* More precisely:
|
|
|
|
*
|
|
|
|
* - CPU instance creation (instance_init) will run only CPU
|
|
|
|
* model loading. CPU expansion can't run at instance_init-time
|
|
|
|
* because host/accelerator data may be not available yet.
|
|
|
|
* - CPU realization will perform both CPU model expansion and CPUID
|
|
|
|
* filtering, and return an error in case one of them fails.
|
|
|
|
* - query-cpu-definitions needs to run all 3 steps. It needs
|
|
|
|
* to run CPUID filtering, as the 'unavailable-features'
|
|
|
|
* field is set based on the filtering results.
|
|
|
|
* - The query-cpu-model-expansion QMP command only needs to run
|
|
|
|
* CPU model loading and CPU expansion. It should not filter
|
|
|
|
* any CPUID data based on host capabilities.
|

target-i386: Set AMD alias bits after filtering CPUID data
QEMU complains about -cpu host on an AMD machine:
warning: host doesn't support requested feature: CPUID.80000001H:EDX [bit 0]
For bits 0,1,3,4,5,6,7,8,9,12,13,14,15,16,17,23,24.
KVM_GET_SUPPORTED_CPUID and and x86_cpu_get_migratable_flags()
don't handle the AMD CPUID aliases bits, making
x86_cpu_filter_features() print warnings and clear those CPUID
bits incorrectly.
To avoid hacking x86_cpu_get_migratable_flags() to handle
CPUID_EXT2_AMD_ALIASES (just like the existing hack inside
kvm_arch_get_supported_cpuid()), simply move the
CPUID_EXT2_AMD_ALIASES code in x86_cpu_realizefn() after the
x86_cpu_filter_features() call.
This will probably make the CPUID_EXT2_AMD_ALIASES hack in
kvm_arch_get_supported_cpuid() unnecessary, too. The hack will be
removed in a follow-up patch after v2.6.0.

qdev: Unrealize must not fail
Devices may have component devices and buses.
Device realization may fail. Realization is recursive: a device's
realize() method realizes its components, and device_set_realized()
realizes its buses (which should in turn realize the devices on that
bus, except bus_set_realized() doesn't implement that, yet).
When realization of a component or bus fails, we need to roll back:
unrealize everything we realized so far. If any of these unrealizes
failed, the device would be left in an inconsistent state. Must not
happen.
device_set_realized() lets it happen: it ignores errors in the roll
back code starting at label child_realize_fail.
Since realization is recursive, unrealization must be recursive, too.
But how could a partly failed unrealize be rolled back? We'd have to
re-realize, which can fail. This design is fundamentally broken.
device_set_realized() does not roll back at all. Instead, it keeps
unrealizing, ignoring further errors.
It can screw up even for a device with no buses: if the lone
dc->unrealize() fails, it still unregisters vmstate, and calls
listeners' unrealize() callback.
bus_set_realized() does not roll back either. Instead, it stops
unrealizing.
Fortunately, no unrealize method can fail, as we'll see below.
To fix the design error, drop parameter @errp from all the unrealize
methods.
Any unrealize method that uses @errp now needs an update. This leads
us to unrealize() methods that can fail. Merely passing it to another
unrealize method cannot cause failure, though. Here are the ones that
do other things with @errp:
* virtio_serial_device_unrealize()
Fails when qbus_set_hotplug_handler() fails, but still does all the
other work. On failure, the device would stay realized with its
resources completely gone. Oops. Can't happen, because
qbus_set_hotplug_handler() can't actually fail here. Pass
&error_abort to qbus_set_hotplug_handler() instead.
* hw/ppc/spapr_drc.c's unrealize()
Fails when object_property_del() fails, but all the other work is
already done. On failure, the device would stay realized with its
vmstate registration gone. Oops. Can't happen, because
object_property_del() can't actually fail here. Pass &error_abort
to object_property_del() instead.
* spapr_phb_unrealize()
Fails and bails out when remove_drcs() fails, but other work is
already done. On failure, the device would stay realized with some
of its resources gone. Oops. remove_drcs() fails only when
chassis_from_bus()'s object_property_get_uint() fails, and it can't
here. Pass &error_abort to remove_drcs() instead.
Therefore, no unrealize method can fail before this patch.
device_set_realized()'s recursive unrealization via bus uses
object_property_set_bool(). Can't drop @errp there, so pass
&error_abort.
We similarly unrealize with object_property_set_bool() elsewhere,
always ignoring errors. Pass &error_abort instead.
Several unrealize methods no longer handle errors from other unrealize
methods: virtio_9p_device_unrealize(),
virtio_input_device_unrealize(), scsi_qdev_unrealize(), ...
Much of the deleted error handling looks wrong anyway.
One unrealize methods no longer ignore such errors:
usb_ehci_pci_exit().
Several realize methods no longer ignore errors when rolling back:
v9fs_device_realize_common(), pci_qdev_unrealize(),
spapr_phb_realize(), usb_qdev_realize(), vfio_ccw_realize(),
virtio_device_realize().

qom: Swap 'name' next to visitor in ObjectPropertyAccessor
Similar to the previous patch, it's nice to have all functions
in the tree that involve a visitor and a name for conversion to
or from QAPI to consistently stick the 'name' parameter next
to the Visitor parameter.
Done by manually changing include/qom/object.h and qom/object.c,
then running this Coccinelle script and touching up the fallout
(Coccinelle insisted on adding some trailing whitespace).

qapi: Swap visit_* arguments for consistent 'name' placement
JSON uses "name":value, but many of our visitor interfaces were
called with visit_type_FOO(v, &value, name, errp). This can be
a bit confusing to have to mentally swap the parameter order to
match JSON order. It's particularly bad for visit_start_struct(),
where the 'name' parameter is smack in the middle of the
otherwise-related group of 'obj, kind, size' parameters! It's
time to do a global swap of the parameter ordering, so that the
'name' parameter is always immediately after the Visitor argument.
Additional reason in favor of the swap: the existing include/qjson.h
prefers listing 'name' first in json_prop_*(), and I have plans to
unify that file with the qapi visitors; listing 'name' first in
qapi will minimize churn to the (admittedly few) qjson.h clients.
Later patches will then fix docs, object.h, visitor-impl.h, and
those clients to match.
Done by first patching scripts/qapi*.py by hand to make generated
files do what I want, then by running the following Coccinelle
script to affect the rest of the code base:
$ spatch --sp-file script `git grep -l '\bvisit_' -- '**/*.[ch]'`
I then had to apply some touchups (Coccinelle insisted on TAB
indentation in visitor.h, and botched the signature of
visit_type_enum() by rewriting 'const char *const strings[]' to
the syntactically invalid 'const char*const[] strings'). The
movement of parameters is sufficient to provoke compiler errors
if any callers were missed.

qom: Swap 'name' next to visitor in ObjectPropertyAccessor
Similar to the previous patch, it's nice to have all functions
in the tree that involve a visitor and a name for conversion to
or from QAPI to consistently stick the 'name' parameter next
to the Visitor parameter.
Done by manually changing include/qom/object.h and qom/object.c,
then running this Coccinelle script and touching up the fallout
(Coccinelle insisted on adding some trailing whitespace).

error: Eliminate error_propagate() with Coccinelle, part 1
When all we do with an Error we receive into a local variable is
propagating to somewhere else, we can just as well receive it there
right away. Convert
if (!foo(..., &err)) {
...
error_propagate(errp, err);
...
return ...
}
to
if (!foo(..., errp)) {
...
...
return ...
}

Not exactly elegant, I'm afraid.
The "when != lbl:" is necessary to avoid transforming
if (fun(args, &err)) {
goto out
}
...
out:
error_propagate(errp, err);
even though other paths to label out still need the error_propagate().
For an actual example, see sclp_realize().
Without the "when strict", Coccinelle transforms vfio_msix_setup(),
incorrectly. I don't know what exactly "when strict" does, only that
it helps here.
The match of return is narrower than what I want, but I can't figure
out how to express "return where the operand doesn't use @err". For
an example where it's too narrow, see vfio_intx_enable().
Silently fails to convert hw/arm/armsse.c, because Coccinelle gets
confused by ARMSSE being used both as typedef and function-like macro
there. Converted manually.
Line breaks tidied up manually. One nested declaration of @local_err
deleted manually. Preexisting unwanted blank line dropped in
hw/riscv/sifive_e.c.

i386: run accel_cpu_instance_init as post_init
This fixes host and max cpu initialization, by running the accel cpu
initialization only after all instance init functions are called for all
X86 cpu subclasses.
The bug this is fixing is related to the "max" and "host" i386 cpu
subclasses, which set cpu->max_features, which is then used at cpu
realization time.
In order to properly split the accel-specific max features code that
needs to be executed at cpu instance initialization time,
we cannot call the accel cpu initialization at the end of the x86 base
class initialization, or we will have no way to specialize
"max features" cpu behavior, overriding the "max" cpu class defaults,
and checking for the "max features" flag itself.
This patch moves the accel-specific cpu instance initialization to after
all x86 cpu instance code has been executed, including subclasses,
so that proper initialization of cpu "host" and "max" can be restored.

qom: Drop parameter @errp of object_property_add() & friends
The only way object_property_add() can fail is when a property with
the same name already exists. Since our property names are all
hardcoded, failure is a programming error, and the appropriate way to
handle it is passing &error_abort.
Same for its variants, except for object_property_add_child(), which
additionally fails when the child already has a parent. Parentage is
also under program control, so this is a programming error, too.
We have a bit over 500 callers. Almost half of them pass
&error_abort, slightly fewer ignore errors, one test case handles
errors, and the remaining few callers pass them to their own callers.
The previous few commits demonstrated once again that ignoring
programming errors is a bad idea.
Of the few ones that pass on errors, several violate the Error API.
The Error ** argument must be NULL, &error_abort, &error_fatal, or a
pointer to a variable containing NULL. Passing an argument of the
latter kind twice without clearing it in between is wrong: if the
first call sets an error, it no longer points to NULL for the second
call. ich9_pm_add_properties(), sparc32_ledma_realize(),
sparc32_dma_realize(), xilinx_axidma_realize(), xilinx_enet_realize()
are wrong that way.
When the one appropriate choice of argument is &error_abort, letting
users pick the argument is a bad idea.
Drop parameter @errp and assert the preconditions instead.
There's one exception to "duplicate property name is a programming
error": the way object_property_add() implements the magic (and
undocumented) "automatic arrayification". Don't drop @errp there.
Instead, rename object_property_add() to object_property_try_add(),
and add the obvious wrapper object_property_add().

handle it is passing &error_abort.
Same for its variants, except for object_property_add_child(), which
additionally fails when the child already has a parent. Parentage is
also under program control, so this is a programming error, too.
We have a bit over 500 callers. Almost half of them pass
&error_abort, slightly fewer ignore errors, one test case handles
errors, and the remaining few callers pass them to their own callers.
The previous few commits demonstrated once again that ignoring
programming errors is a bad idea.
Of the few ones that pass on errors, several violate the Error API.
The Error ** argument must be NULL, &error_abort, &error_fatal, or a
pointer to a variable containing NULL. Passing an argument of the
latter kind twice without clearing it in between is wrong: if the
first call sets an error, it no longer points to NULL for the second
call. ich9_pm_add_properties(), sparc32_ledma_realize(),
sparc32_dma_realize(), xilinx_axidma_realize(), xilinx_enet_realize()
are wrong that way.
When the one appropriate choice of argument is &error_abort, letting
users pick the argument is a bad idea.
Drop parameter @errp and assert the preconditions instead.
There's one exception to "duplicate property name is a programming
error": the way object_property_add() implements the magic (and
undocumented) "automatic arrayification". Don't drop @errp there.
Instead, rename object_property_add() to object_property_try_add(),
and add the obvious wrapper object_property_add().

target-i386: present virtual L3 cache info for vcpus
Some software algorithms are based on the hardware's cache info, for example,
for x86 linux kernel, when cpu1 want to wakeup a task on cpu2, cpu1 will trigger
a resched IPI and told cpu2 to do the wakeup if they don't share low level
cache. Oppositely, cpu1 will access cpu2's runqueue directly if they share llc.
The relevant linux-kernel code as bellow:
static void ttwu_queue(struct task_struct *p, int cpu)
{
struct rq *rq = cpu_rq(cpu);
......
if (... && !cpus_share_cache(smp_processor_id(), cpu)) {
......
ttwu_queue_remote(p, cpu); /* will trigger RES IPI */
return;
}
......
ttwu_do_activate(rq, p, 0); /* access target's rq directly */
......
}
In real hardware, the cpus on the same socket share L3 cache, so one won't
trigger a resched IPIs when wakeup a task on others. But QEMU doesn't present a
virtual L3 cache info for VM, then the linux guest will trigger lots of RES IPIs
under some workloads even if the virtual cpus belongs to the same virtual socket.
For KVM, there will be lots of vmexit due to guest send IPIs.
The workload is a SAP HANA's testsuite, we run it one round(about 40 minuates)
and observe the (Suse11sp3)Guest's amounts of RES IPIs which triggering during
the period:
No-L3 With-L3(applied this patch)
cpu0: 363890 44582
cpu1: 373405 43109
cpu2: 340783 43797
cpu3: 333854 43409
cpu4: 327170 40038

cpu13: 172269 35805
cpu14: 179979 33898
cpu15: 194505 32754
avg: 268963.6 40129.8
The VM's topology is "1*socket 8*cores 2*threads".
After present virtual L3 cache info for VM, the amounts of RES IPIs in guest
reduce 85%.
For KVM, vcpus send IPIs will cause vmexit which is expensive, so it can cause
severe performance degradation. We had tested the overall system performance if
vcpus actually run on sparate physical socket. With L3 cache, the performance
improves 7.2%~33.1%(avg:15.7%).

cpu: Use DeviceClass reset instead of a special CPUClass reset
The CPUClass has a 'reset' method. This is a legacy from when
TYPE_CPU used not to inherit from TYPE_DEVICE. We don't need it any
more, as we can simply use the TYPE_DEVICE reset. The 'cpu_reset()'
function is kept as the API which most places use to reset a CPU; it
is now a wrapper which calls device_cold_reset() and then the
tracepoint function.
This change should not cause CPU objects to be reset more often
than they are at the moment, because:
* nobody is directly calling device_cold_reset() or
qdev_reset_all() on CPU objects
* no CPU object is on a qbus, so they will not be reset either
by somebody calling qbus_reset_all()/bus_cold_reset(), or
by the main "reset sysbus and everything in the qbus tree"
reset that most devices are reset by
Note that this does not change the need for each machine or whatever
to use qemu_register_reset() to arrange to call cpu_reset() -- that
is necessary because CPU objects are not on any qbus, so they don't
get reset when the qbus tree rooted at the sysbus bus is reset, and
this isn't being changed here.
All the changes to the files under target/ were made using the
included Coccinelle script, except:
(1) the deletion of the now-inaccurate and not terribly useful
"CPUClass::reset" comments was done with a perl one-liner afterwards:
perl -n -i -e '/ CPUClass::reset/ or print' target/*/*.c
(2) this bit of the s390 change was done by hand, because the
Coccinelle script is not sophisticated enough to handle the
parent_reset call being inside another function:

qdev: Protect device-list-properties against broken devices
Several devices don't survive object_unref(object_new(T)): they crash
or hang during cleanup, or they leave dangling pointers behind.
This breaks at least device-list-properties, because
qmp_device_list_properties() needs to create a device to find its
properties. Broken in commit f4eb32b "qmp: show QOM properties in
device-list-properties", v2.1. Example reproducer:
$ qemu-system-aarch64 -nodefaults -display none -machine none -S -qmp stdio
{"QMP": {"version": {"qemu": {"micro": 50, "minor": 4, "major": 2}, "package": ""}, "capabilities": []}}
{ "execute": "qmp_capabilities" }
{"return": {}}
{ "execute": "device-list-properties", "arguments": { "typename": "pxa2xx-pcmcia" } }
qemu-system-aarch64: /home/armbru/work/qemu/memory.c:1307: memory_region_finalize: Assertion `((&mr->subregions)->tqh_first == ((void *)0))' failed.
Aborted (core dumped)
[Exit 134 (SIGABRT)]
Unfortunately, I can't fix the problems in these devices right now.
Instead, add DeviceClass member cannot_destroy_with_object_finalize_yet
to mark them:
* Hang during cleanup (didn't debug, so I can't say why):
"realview_pci", "versatile_pci".
* Dangling pointer in cpus: most CPUs, plus "allwinner-a10", "digic",

assertion, because the CPUs are only registered when KVM is enabled,
but the assertion is arguably in the wrong place all the same)
Make qmp_device_list_properties() fail cleanly when the device is so
marked. This improves device-list-properties from "crashes, hangs or
leaves dangling pointers behind" to "fails". Not a complete fix, just
a better-than-nothing work-around. In the above reproducer,
device-list-properties now fails with "Can't list properties of device
'pxa2xx-pcmcia'".
This also protects -device FOO,help, which uses the same machinery
since commit ef52358 "qdev-monitor: include QOM properties in -device
FOO, help output", v2.2. Example reproducer:
$ qemu-system-aarch64 -machine none -device pxa2xx-pcmcia,help
Before:
qemu-system-aarch64: .../memory.c:1307: memory_region_finalize: Assertion `((&mr->subregions)->tqh_first == ((void *)0))' failed.
After:
Can't list properties of device 'pxa2xx-pcmcia'

i386: run accel_cpu_instance_init as post_init
This fixes host and max cpu initialization, by running the accel cpu
initialization only after all instance init functions are called for all
X86 cpu subclasses.
The bug this is fixing is related to the "max" and "host" i386 cpu
subclasses, which set cpu->max_features, which is then used at cpu
realization time.
In order to properly split the accel-specific max features code that
needs to be executed at cpu instance initialization time,
we cannot call the accel cpu initialization at the end of the x86 base
class initialization, or we will have no way to specialize
"max features" cpu behavior, overriding the "max" cpu class defaults,
and checking for the "max features" flag itself.
This patch moves the accel-specific cpu instance initialization to after
all x86 cpu instance code has been executed, including subclasses,
so that proper initialization of cpu "host" and "max" can be restored.

i386: Define static "base" CPU model
The query-cpu-model-expand QMP command needs at least one static
model, to allow the "static" expansion mode to be implemented.
Instead of defining static versions of every CPU model, define a
"base" CPU model that has absolutely no feature flag enabled.
Despite having no CPUID data set at all, "-cpu base" is even a
functional CPU:
* It can boot a Slackware Linux 1.01 image with a Linux 0.99.12
kernel[1].
* It is even possible to boot[2] a modern Fedora x86_64 guest by
manually enabling the following CPU features:
