4100d5e6dc hw/riscv: hart: Add a new 'resetvec' property
RISC-V machines do not instantiate RISC-V CPUs directly, instead
they do that via the hart array. Add a new property for the reset
vector address to allow the value to be passed to the CPU, before
CPU is realized.

The kernel does a 16-bit write when powering off the machine, which
was allowed before commit 5d971f9e67 ("memory: Revert "memory: accept
mismatching sizes in memory_region_access_valid""). Make min_access_size
match reality so that the machine can shut down properly now.

b15e402fc8 trace-events: Fix attribution of trace points to source
Some trace points are attributed to the wrong source file.  Happens
when we neglect to update trace-events for code motion, or add events
in the wrong place, or misspell the file name.

Clean up with help of scripts/cleanup-trace-events.pl.  Funnies
requiring manual post-processing:

* accel/tcg/cputlb.c trace points are in trace-events.

* block.c and blockdev.c trace points are in block/trace-events.

* hw/block/nvme.c uses the preprocessor to hide its trace point use
  from cleanup-trace-events.pl.

* hw/tpm/tpm_spapr.c uses pseudo trace point tpm_spapr_show_buffer to
  guard debug code.

* include/hw/xen/xen_common.h trace points are in hw/xen/trace-events.

* linux-user/trace-events abbreviates a tedious list of filenames to
  */signal.c.

* net/colo-compare and net/filter-rewriter.c use pseudo trace points
  colo_compare_miscompare and colo_filter_rewriter_debug to guard
  debug code.

Generated initially using:

 $ ./scripts/codeconverter/converter.py --force -i \

Then each case was manually reviewed, and a comment was added
indicating what's unusual about those type checking
macros/functions.  Despite not following the usual pattern, the
changes in this patch were found to be safe.

db1015e92e Move QOM typedefs and add missing includes

 $ ./scripts/codeconverter/converter.py -i \
   --pattern=QOMStructTypedefSplit $(git grep -l '' -- '*.[ch]')

which will split "typdef struct { ... } TypedefName"

Followed by:

 $ ./scripts/codeconverter/converter.py -i --pattern=MoveSymbols \
    $(git grep -l '' -- '*.[ch]')

which will:
- move the typedefs and #defines above the type check macros
- add missing #include "qom/object.h" lines if necessary

b95ba83fc5 ppc patch queue 2020-09-08
This supersedes ppc-for-5.2-20200904, it fixes a couple of bugs in
 that PR and adds a few extra patches.
 
 Next pull request for qemu-5.2.  The biggest thing here is the
 generalization of ARM's start-powered-off machine property to all
 targets.  This can fix a number of odd little edge cases where KVM
 could run vcpus before they were properly initialized.  This does
 include changes to a number of files that aren't normally in my
 purview.  There are suitable Acked-by lines and Peter requested this
 come in via my tree, since the most pressing requirement for it is in
 pseries machines with the POWER secure virtual machine facility.
 
 In addition we have:
  * Daniel Barboza's rework and clean up of pseries machine NUMA handling
  * Correction to behaviour of the nvdimm= generic machine property on
    pseries
  * An optimization to the allocation of XIVE interrupts on KVM
  * Some fixes for confused behaviour with kernel_irqchip when both

ppc patch queue 2020-09-08

This supersedes ppc-for-5.2-20200904, it fixes a couple of bugs in
that PR and adds a few extra patches.

Next pull request for qemu-5.2.  The biggest thing here is the
generalization of ARM's start-powered-off machine property to all
targets.  This can fix a number of odd little edge cases where KVM
could run vcpus before they were properly initialized.  This does
include changes to a number of files that aren't normally in my
purview.  There are suitable Acked-by lines and Peter requested this
come in via my tree, since the most pressing requirement for it is in
pseries machines with the POWER secure virtual machine facility.

In addition we have:
 * Daniel Barboza's rework and clean up of pseries machine NUMA handling
 * Correction to behaviour of the nvdimm= generic machine property on
   pseries
 * An optimization to the allocation of XIVE interrupts on KVM
 * Some fixes for confused behaviour with kernel_irqchip when both
   XICS and XIVE are in play
 * Add HIOMAP comamnd to pnv flash
 * Properly advertise the fact that spapr_vscsi doesn't handle
   hotplugged disks
 * Some assorted minor enhancements

feabc71dfa configure: do not include dependency flags in QEMU_CFLAGS and LIBS
All Meson executables should specify their dependencies explicitly, either
directly or indirectly via declare_dependency.  Makefiles instead did
not propagate dependencies correctly from static libraries, for example.
Therefore, flags for dependencies need not be included in QEMU_CFLAGS.
LIBS is not used at all, so drop that one as well.

In a few cases the dependencies were not yet specified, so add them.

876ab8d89d spapr_numa: use spapr_numa_get_vcpu_assoc() in home_node hcall
The current implementation of h_home_node_associativity hard codes
the values of associativity domains of the vcpus. Let's make
it consider the values already initialized in spapr->numa_assoc_array,
via the spapr_numa_get_vcpu_assoc() helper.

We want to set it and forget it, and for that we also need to
assert that we don't overflow the registers of the hypercall.
>From R4 to R9 we can squeeze in 12 associativity domains for
vcpus, so let's assert that VCPU_ASSOC_SIZE -1 isn't greater
than that.

8f86a40824 spapr, spapr_numa: handle vcpu ibm,associativity
Vcpus have an additional paramenter to be appended, vcpu_id. This
also changes the size of the of property itself, which is being
represented in index 0 of numa_assoc_array[cpu->node_id],
and defaults to MAX_DISTANCE_REF_POINTS for all cases but
vcpus.

All this logic makes more sense in spapr_numa.c, where we handle
everything NUMA and associativity. A new helper spapr_numa_fixup_cpu_dt()
was added, and spapr.c uses it the same way as it was using the former
spapr_fixup_cpu_numa_dt().

f1aa45fffe spapr: introduce SpaprMachineState::numa_assoc_array
The next step to centralize all NUMA/associativity handling in
the spapr machine is to create a 'one stop place' for all
things ibm,associativity.

This patch introduces numa_assoc_array, a 2 dimensional array
that will store all ibm,associativity arrays of all NUMA nodes.
This array is initialized in a new spapr_numa_associativity_init()
function, called in spapr_machine_init(). It is being initialized
with the same values used in other ibm,associativity properties
around spapr files (i.e. all zeros, last value is node_id).
The idea is to remove all hardcoded definitions and FDT writes
of ibm,associativity arrays, doing instead a call to the new
helper spapr_numa_write_associativity_dt() helper, that will
be able to write the DT with the correct values.

We'll start small, handling the trivial cases first. The
remaining instances of ibm,associativity will be handled
next.

1eee995026 ppc: introducing spapr_numa.c NUMA code helper
We're going to make changes in how spapr handles all
ibm,associativity* related properties to enhance our current NUMA
support.

At this moment we have associativity code scattered all around
spapr_* files, with hardcoded values and array sizes. This
makes it harder to change any NUMA specific parameters in
the future. Having everything in the same place allows not
only for easier tuning, but also easier understanding since all
NUMA related code is on the same file.

This patch introduces a new file to gather all NUMA/associativity
handling code in spapr, spapr_numa.c. To get things started, let's
remove associativity-reference-points and max-associativity-domains
code from spapr_dt_rtas() to a new helper called spapr_numa_write_rtas_dt().
This will decouple spapr_dt_rtas() from the NUMA changes that
are going to happen in those two properties.

24f675cd3b sparc/sun4m: Use start-powered-off CPUState property
Instead of setting CPUState::halted to 1 in secondary_cpu_reset(), use the
start-powered-off property which makes cpu_common_reset() initialize it
to 1 in common code.

Now secondary_cpu_reset() becomes equivalent to main_cpu_reset() so rename
the function to sun4m_cpu_reset().

Also remove setting of cs->halted from cpu_devinit(), which seems out of
place when compared to similar code in other architectures (e.g.,
ppce500_init() in hw/ppc/e500.c).

Finally, change creation of CPU object from cpu_create() to object_new()
and qdev_realize_and_unref() because cpu_create() realizes the CPU and it's
not possible to set a property after the object is realized.

554c2169e9 ppc/spapr: Use start-powered-off CPUState property
PowerPC sPAPR CPUs start in the halted state, and spapr_reset_vcpu()
attempts to implement this by setting CPUState::halted to 1. But that's too
late for the case of hotplugged CPUs in a machine configure with 2 or more
threads per core.

By then, other parts of QEMU have already caused the vCPU to run in an
unitialized state a couple of times. For example, ppc_cpu_reset() calls
ppc_tlb_invalidate_all(), which ends up calling async_run_on_cpu(). This
kicks the new vCPU while it has CPUState::halted = 0, causing QEMU to issue
a KVM_RUN ioctl on the new vCPU before the guest is able to make the
start-cpu RTAS call to initialize its register state.

This problem doesn't seem to cause visible issues for regular guests, but
on a secure guest running under the Ultravisor it does. The Ultravisor
relies on being able to snoop on the start-cpu RTAS call to map vCPUs to
guests, and this issue causes it to see a stray vCPU that doesn't belong to
any guest.

Fix by setting the start-powered-off CPUState property in
spapr_create_vcpu(), which makes cpu_common_reset() initialize
CPUState::halted to 1 at an earlier moment.

28f5a71621 ppc/spapr_nvdimm: do not enable support with 'nvdimm=off'
The NVDIMM support for pSeries was introduced in 5.1, but it
didn't contemplate the 'nvdimm' machine option that other
archs uses. For every other arch, if no '-machine nvdimm(=on)'
is present, it is assumed that the NVDIMM support is disabled.
The user must explictly inform that the machine supports
NVDIMM. For pseries-5.1 the 'nvdimm' option is completely
ignored, and support is always assumed to exist. This
leads to situations where the user is able to set 'nvdimm=off'
but the guest boots up with the NVDIMMs anyway.

Fixing this now, after 5.1 launch, can put the overall NVDIMM
support for pseries in a strange place regarding this 'nvdimm'
machine option. If we force everything to be like other archs,
existing pseries-5.1 guests that didn't use 'nvdimm' to use NVDIMM
devices will break. If we attempt to make the newer pseries
machines (5.2+) behave like everyone else, but keep pseries-5.1
untouched, we'll have consistency problems on machine upgrade
(5.1 will have different default values for NVDIMM support than
5.2).

The common ground here is, if the user sets 'nvdimm=off', we
must comply regardless of being 5.1 or 5.2+. This patch
changes spapr_nvdimm_validate() to verify if the user set
NVDIMM support off in the machine options and, in that
case, error out if we have a NVDIMM device. The default
value for 5.2+ pseries machines will still be 'nvdimm=on'
when there is no 'nvdimm' option declared, just like it is today
with pseries-5.1. In the end we'll have different default
semantics from everyone else in the absence of the 'nvdimm'
machine option, but this boat has sailed.

beb6073fe7 spapr, spapr_nvdimm: fold NVDIMM validation in the same place
NVDIMM has different contraints and conditions than the regular
DIMM and we'll need to add at least one more.

Instead of relying on 'if (nvdimm)' conditionals in the body of
spapr_memory_pre_plug(), use the existing spapr_nvdimm_validate_opts()
and put all NVDIMM handling code there. Rename it to
spapr_nvdimm_validate() to reflect that the function is now checking
more than the nvdimm device options. This makes spapr_memory_pre_plug()
a bit easier to follow, and we can tune in NVDIMM parameters
and validation in the same place.

eab0a2d06e spapr/xive: Allocate vCPU IPIs from the vCPU contexts
When QEMU switches to the XIVE interrupt mode, it creates all the
guest interrupts at the level of the KVM device. These interrupts are
backed by real HW interrupts from the IPI interrupt pool of the XIVE
controller.

Currently, this is done from the QEMU main thread, which results in
allocating all interrupts from the chip on which QEMU is running. IPIs
are not distributed across the system and the load is not well
balanced across the interrupt controllers.

Change the vCPU IPI allocation to run from the vCPU context. The
associated XIVE IPI interrupt will be allocated on the chip on which
the vCPU is running and improve distribution of the IPIs in the system.
When the vCPUs are pinned, this will make the IPI local to the chip of
the vCPU. It will reduce rerouting between interrupt controllers and
gives better performance.

Device interrupts are still treated the same. To improve placement, we
would need some information on the chip owning the virtual source or
the HW source in case of a passthrough device but this reuires
changes in PAPR.

b31911c616 spapr/xive: Use the xics flag to check for XIVE-only IRQ backends
The sPAPR machine has four different IRQ backends, each implementing
the XICS or XIVE interrupt mode or both in the case of the 'dual'
backend.

If a machine is started in P8 compat mode, QEMU should necessarily
support the XICS interrupt mode and in that case, the XIVE-only IRQ
backend is invalid. Currently, spapr_irq_check() tests the pointer
value to the IRQ backend to check for this condition, instead use the
'xics' flag. It's equivalent and it will ease the introduction of new
XIVE-only IRQ backends if needed.

Until now the TLB size was fixed at 256 entries. To allow operating
systems to utilize more TLB entries in the future, we need to tell
firmware how many TLB entries we actually support in the emulation.
Firmware then reports this to the operating system via the
PDC_CACHE_INFO call.

This patch simply does the preparation to allow more TLB entries.

map to the buffer with a wrong length.

Similarly, if the Select (SEL) field is set to request saved values, the
devices will (as it should) return the default values instead.

Since this also introduces "Supported Capabilities", the nsid field is
now also checked for validity wrt. the feature being get/set'ed.

dccb92b5ca hw/misc/sbsa_ec : Add an embedded controller for sbsa-ref
A difference between sbsa platform and the virt platform is PSCI is
handled by ARM-TF in the sbsa platform. This means that the PSCI code
there needs to communicate some of the platform power changes down
to the qemu code for things like shutdown/reset control.

Space has been left to extend the EC if we find other use cases in
future where ARM-TF and qemu need to communicate.

999f6ebde5 hw/arm/sbsa-ref: add "reg" property to DT cpu nodes
The sbsa-ref platform uses a minimal device tree to pass amount of memory
as well as number of cpus to the firmware. However, when dumping that
minimal dtb (with -M sbsa-virt,dumpdtb=<file>), the resulting blob
generates a warning when decompiled by dtc due to lack of reg property.

Add a simple reg property per cpu, representing a 64-bit MPIDR_EL1.

This also ends up being cleaner than having the firmware calculating its
own IDs for generating APCI.

1f240ca1eb aspeed/smc: Open AHB window of the second chip of the AST2600 FMC controller
This change works around the HW default values to be able to test the
Tacoma board with -kernel command line option. This was required when
we had both flash chips enabled in the device tree, otherwise Linux
would fail to probe the entire controller leaving it with no rootfs.

14c179541b aspeed/sdmc: Perform memory training
This allows qemu to run the "normal" power on reset boot path through
u-boot, where the DDR is trained.

An enhancement would be to have the SCU bit stick across qemu reboots,
but be unset on initial boot.

Proper modelling would be to discard all writes to the phy setting regs
at offset 0x100 - 0x400 and to model the phy status regs at offset
0x400.

The status regs model would only need to account for offets 0x00,
0x50, 0x68 and 0x7c.

c2ab73fcbe ftgmac100: Fix integer overflow in ftgmac100_do_tx()
When inserting the VLAN tag in packets, memmove() can generate an
integer overflow for packets whose length is less than 12 bytes.

Move the VLAN insertion when the last segment of the frame is reached
and check length against the size of the ethernet header (14 bytes) to
avoid the crash. Return FTGMAC100_INT_XPKT_LOST status if the frame is
too small. This seems like a good modeling choice even if Aspeed does
not specify anything in that case.

The model uses today the "Normal priority transmit buffer unavailable"
interrupt status which it is not appropriate. According to the Aspeed
specs, no interrupts are raised in that case. An "AHB error" status
seems like a better modeling choice for all implementations since it
is covered by the Linux kernel.

740bc3a7e6 aspeed/scu: Fix valid access size on AST2400
The read access size of the SCU registers can be 1/2/4 bytes and write
is 4 bytes and all Aspeed models would need a .valid.accepts() handler.

For the moment, set the min access size to 1 byte to cover both read
and write operations on the AST2400 but keep the min access size of
the other SoCs to 4 bytes as this is an unusual access size.

This fixes support for some old firmware doing 2 bytes reads on the
AST2400 SoC.
