The kernel provides similar emulation of PCI BAR register access to
QEMU, so up until now we've used that for things like BAR sizing and
storing the BAR address. However, if we intend to resize BARs or add
BARs that don't exist on the physical device, we need to switch to the
pure QEMU emulation of the BAR.

Add one more layer to our stack of MemoryRegions, this base region
allows us to register BARs independently of the vfio region or to
extend the size of BARs which do map to a region. This will be
useful when we want hypervisor defined BARs or sections of BARs,
for purposes such as relocating MSI-X emulation. We therefore call
msix_init() based on this new base MemoryRegion, while the quirks,
which only modify regions still operate on those sub-MemoryRegions.

In order to enable TCE operations support in KVM, we have to inform
the KVM about VFIO groups being attached to specific LIOBNs;
the necessary bits are implemented already by IOMMU MR and VFIO.
This defines get_attr() for the SPAPR TCE IOMMU MR which makes VFIO
call the KVM_DEV_VFIO_GROUP_SET_SPAPR_TCE ioctl and establish
LIOBN-to-IOMMU link.
This changes spapr_tce_set_need_vfio() to avoid TCE table reallocation
if the kernel supports the TCE acceleration.

In order to enable TCE operations support in KVM, we have to inform
the KVM about VFIO groups being attached to specific LIOBNs. The KVM
already knows about VFIO groups, the only bit missing is which
in-kernel TCE table (the one with user visible TCEs) should update
the attached broups. There is an KVM_DEV_VFIO_GROUP_SET_SPAPR_TCE
attribute of the VFIO KVM device which receives a groupfd/tablefd couple.
This uses a new memory_region_iommu_get_attr() helper to get the IOMMU fd
and calls KVM to establish the link.
As get_attr() is not implemented yet, this should cause no behavioural
change.

The purpose of virtio-9p-test is to test the virtio-9p device, especially
the 9p server state machine. We don't really care what fsdev backend we're
using. Moreover, if we want to be able to test the flush request or a
device reset with in-flights I/O, it is close to impossible to achieve
with a physical backend because we cannot ask it reliably to put an I/O
on hold at a specific point in time.
Fortunately, we can do that with the synthetic backend, which allows to
register callbacks on read/write accesses to a specific file. This will
be used by a later patch to test the 9P flush request.
The walk request test is converted to using the synth backend.

# Background
I was investigating spurious non-deterministic EINTR returns from
various 9p file system operations in a Linux guest served from the
qemu 9p server.
## EINTR, ERESTARTSYS and the linux kernel
When a signal arrives that the Linux kernel needs to deliver to user-space
while a given thread is blocked (in the 9p case waiting for a reply to its
request in 9p_client_rpc -> wait_event_interruptible), it asks whatever
driver is currently running to abort its current operation (in the 9p case
causing the submission of a TFLUSH message) and return to user space.
In these situations, the error message reported is generally ERESTARTSYS.
If the userspace processes specified SA_RESTART, this means that the
system call will get restarted upon completion of the signal handler
delivery (assuming the signal handler doesn't modify the process state
in complicated ways not relevant here). If SA_RESTART is not specified,
ERESTARTSYS gets translated to EINTR and user space is expected to handle
the restart itself.
## The 9p TFLUSH command
The 9p TFLUSH commands requests that the server abort an ongoing operation.
The man page [1] specifies:
```
If it recognizes oldtag as the tag of a pending transaction, it should
abort any pending response and discard that tag.
[...]
When the client sends a Tflush, it must wait to receive the corresponding
Rflush before reusing oldtag for subsequent messages. If a response to the
flushed request is received before the Rflush, the client must honor the
response as if it had not been flushed, since the completed request may
signify a state change in the server
```
In particular, this means that the server must not send a reply with the
orignal tag in response to the cancellation request, because the client is
obligated to interpret such a reply as a coincidental reply to the original
request.
# The bug
When qemu receives a TFlush request, it sets the `cancelled` flag on the
relevant pdu. This flag is periodically checked, e.g. in
`v9fs_co_name_to_path`, and if set, the operation is aborted and the error
is set to EINTR. However, the server then violates the spec, by returning
to the client an Rerror response, rather than discarding the message
entirely. As a result, the client is required to assume that said Rerror
response is a result of the original request, not a result of the
cancellation and thus passes the EINTR error back to user space.
This is not the worst thing it could do, however as discussed above, the
correct error code would have been ERESTARTSYS, such that user space
programs with SA_RESTART set get correctly restarted upon completion of
the signal handler.
Instead, such programs get spurious EINTR results that they were not
expecting to handle.
It should be noted that there are plenty of user space programs that do not
set SA_RESTART and do not correctly handle EINTR either. However, that is
then a userspace bug. It should also be noted that this bug has been
mitigated by a recent commit to the Linux kernel [2], which essentially
prevents the kernel from sending Tflush requests unless the process is about
to die (in which case the process likely doesn't care about the response).
Nevertheless, for older kernels and to comply with the spec, I believe this
change is beneficial.
# Implementation
The fix is fairly simple, just skipping notification of a reply if
the pdu was previously cancelled. We do however, also notify the transport
layer that we're doing this, so it can clean up any resources it may be
holding. I also added a new trace event to distinguish
operations that caused an error reply from those that were cancelled.
One complication is that we only omit sending the message on EINTR errors in
order to avoid confusing the rest of the code (which may assume that a
client knows about a fid if it sucessfully passed it off to pud_complete
without checking for cancellation status). This does mean that if the server
acts upon the cancellation flag, it always needs to set err to EINTR. I
believe this is true of the current code.

The macros were doing ((v) & 1) for a binary input, but that only works
if v == 0 or if v & 1. Changed to !!(v) so they work for all values.
Remove some unused macros.

According to the spec, from section "32.3 OEM SEL Record - Type

tpm_crb is a device for TPM 2.0 Command Response Buffer (CRB)
Interface as defined in TCG PC Client Platform TPM Profile (PTP)
Specification Family “2.0” Level 00 Revision 01.03 v22.
The PTP allows device implementation to switch between TIS and CRB
model at run time, but given that CRB is a simpler device to
implement, I chose to implement it as a different device.
The device doesn't implement other locality than 0 for now (my laptop
TPM doesn't either, so I assume this isn't so bad)
Tested with some success with Linux upstream and Windows 10, seabios &
modified ovmf. The device is recognized and correctly transmit
command/response with passthrough & emu. However, we are missing PPI
ACPI part atm.

NB, the virtio-input device reports a bitmask to the guest driver that
has a bit set for each Linux keycode that the host is able to send to
the guest.
Thus by adding these extra key mappings we are technically changing the
host<->guest ABI. This would also happen any time we defined new mappings
for QEMU keycodes in future.
When a keycode is removed from the list of possible keycodes that host can
send to the guest, it means that the guest OS will think it is possible
to receive a key that in pratice can never be generated, which is harmless.
When a keycode is added to the list of possible keycodes that the host can
send to the guest, it means that the guest OS can see an unexpected event.
The Linux virtio_input.c driver code simply forwards this event to the
input_event() method in the Linux input subsystem. This in turn calls
input_handle_event(), which then calls input_get_disposition(). This method
checks if the input event is present in the permitted keys bitmap, and if
not returns INPUT_IGNORE_EVENT. Thus the unexpected event will get dropped,
which is harmless.
If the guest OS reboots, or otherwise re-initializes the virt-input device,
it will read the new keycode bitmap. No matter how many keys are defined,
the config space has a fixed 128 byte bitmap. There is, however, a size
field defiend which says how many bytes in the bitmap are used. So the guest
OS reads the size of the bitmap, and then it reads the data from bitmap upto
the designated size. So if the guest OS re-initializes at precisely the time
that QEMU is migrated across versions, in the worst case, it could conceivably
read the old size field, but then get the newly updated bitmap. If a key were
added this is harmless, since it simply means it may not process the newly
added key. If a key were removed, then it could be readnig a byte from the
bitmap that was not initialized. Fortunately QEMU always memsets() the entire
bitmap to 0, prior to setting keybits. Thus the guest OS will simply read
zeros, which is again harmless.
Based on this analysis, it is believed that there is no need to preserve the
virtio-input-hid keymaps across migration, as the host<->guest ABI change is
harmless and self-resolving at time of guest reboot.
NB, this behaviour should perhaps be formalized in the virtio-input spec
to declare how guest OS drivers should be written to be robust in their
handling of the potentially changable key bitmaps.

In various place we don't correctly check if the device supports MSI or
MSI-X. This can cause devices to be advertised with MSI support, even
if they only support MSI-X (like virtio-pci-* devices for example):
ethernet@0 {
ibm,req#msi = <0x1>; <--- wrong!
.
ibm,loc-code = "qemu_virtio-net-pci:0000:00:00.0";
.
ibm,req#msi-x = <0x3>;
};
Worse, this can also cause the "ibm,change-msi" RTAS call to corrupt the
PCI status and cause migration to fail:
qemu-system-ppc64: get_pci_config_device: Bad config data: i=0x6
read: 0 device: 10 cmask: 10 wmask: 0 w1cmask:0
^^
PCI_STATUS_CAP_LIST bit which is assumed to be constant
This patch changes spapr_populate_pci_child_dt() to properly check for
MSI support using msi_present(): this ensures that PCIDevice::msi_cap
was set by msi_init() and that msi_nr_vectors_allocated() will look at
the right place in the config space.
Checking PCIDevice::msix_entries_nr is enough for MSI-X but let's add
a call to msix_present() there as well for consistency.
It also changes rtas_ibm_change_msi() to select the appropriate MSI
type in Function 1 instead of always selecting plain MSI. This new
behaviour is compliant with LoPAPR 1.1, as described in "Table 71.
ibm,change-msi Argument Call Buffer":
Function 1: If Number Outputs is equal to 3, request to set to a new
number of MSIs (including set to 0).
If the “ibm,change-msix-capable” property exists and Number
Outputs is equal to 4, request is to set to a new number of
MSI or MSI-X (platform choice) interrupts (including set to
0).
Since MSI is the the platform default (LoPAPR 6.2.3 MSI Option), let's
check for MSI support first.
And finally, it checks the input parameters are valid, as described in
LoPAPR 1.1 "R1–7.3.10.5.1–3":
For the MSI option: The platform must return a Status of -3 (Parameter
error) from ibm,change-msi, with no change in interrupt assignments if
the PCI configuration address does not support MSI and Function 3 was
requested (that is, the “ibm,req#msi” property must exist for the PCI
configuration address in order to use Function 3), or does not support
MSI-X and Function 4 is requested (that is, the “ibm,req#msi-x” property
must exist for the PCI configuration address in order to use Function 4),
or if neither MSIs nor MSI-Xs are supported and Function 1 is requested.
This ensures that the ret_intr_type variable contains a valid MSI type
for this device, and that spapr_msi_setmsg() won't corrupt the PCI status.

qemu-system-ppcemb has been once split of qemu-system-ppc to support
CPU page sizes < 4096 for some of the embedded 4xx PowerPC CPUs.
However, there was hardly any OS available in the wild that really
used such small page sizes (Linux uses 4096 on PPC), so there is
no known recent use case for this separate build anymore. It's
rather cumbersome to maintain a separate set of config switches for
this, and it's wasting compile and test time of all the developers
who have to build all QEMU targets to verify that their changes did
not break anything.
Except for the small CPU page sizes, qemu-system-ppc can be used as
a full replacement for qemu-system-ppcemb since it contains all the
embedded 4xx PPC boards and CPUs, too. Thus let's start the deprecation
process for qemu-system-ppcemb to see whether somebody still needs
the small page sizes or whether we could finally remove this unloved
separate build.

The Xilinx ZynqMP SoC has two main processing systems in it. The ARM
processing system (which is already modeled in QEMU) and the MicroBlaze
Power Management Unit (PMU). This is the inital work for adding support
for the PMU.
The PMU susbsystem runs along side the ARM system on hardware, but due
to architecture limitations in QEMU the two instances are seperate for
the time being.
Let's follow the same setup we do with the ARM system, where there is an
SoC device and a ZCU102 board. Although the PMU is less board specific
we are still going to follow the same split as maybe in future we can
connect the PMU device to the ARM ZCU102 board. As the machine will be
fairly small let's keep them both together in one file.

The option have been marked as deprecated since QEMU 2.10, and so far
nobody complained that the host, serial, disk and net options are urgently
required anymore. So let's now get rid at least of this legacy pile, to
simplify the usb code quite a bit.
This patch removes the usbdevices host, serial, disk and net. These devices
use their own complicated parameter parsing mechanisms, so they are just
ugly to maintain, without real benefit for the users (the users can use the
corresponding "-device" parameters instead which have the same complexity
as the "-usbdevice" devices here).
Note that the other rather simple -usbdevice options (mouse, tablet, etc.)
are not removed yet (the code is really simple here, so it does not hurt
much to keep it), as well as the two devices "braille" and "bt" which are
easier to use with -usbdevice than with -device.

to power down the machine on a real Ultra 5.
The power device exists at offset 0x724000 on a real machine, but due to the
current configuration of the BARs in QEMU it must be located lower in PCI IO
space.
For the moment we place the power device at offset 0x7240 as a reminder of its

This implements rudimentary support for interrupt generation on the
PL110. I am working on a new DRI/KMS driver for Linux and since that
uses the blanking interrupt, we need something to fire here. Without
any interrupt support Linux waits for a while and then gives ugly
messages about the vblank not working in the console (it does not
hang perpetually or anything though, DRI is pretty forgiving).
I solved it for now by setting up a timer to fire at 60Hz and pull
the interrupts for "vertical compare" and "next memory base"
at this interval. This works fine and fires roughly the same number
of IRQs on QEMU as on the hardware and leaves the console clean
and nice.
People who want to create more accurate emulation can probably work
on top of this if need be. It is certainly closer to the hardware
behaviour than what we have today anyway.

failure, and would plough blindly on to crash later trying to use a
NULL CPU object pointer. Detect errors and fail instead.
In particular, this will be necessary to detect the user error
of using "-cpu host" without "-enable-kvm" once we make the host

[PMM: add assert, as the gicv3 code has]
Signed-off-by: Peter Maydell <peter.maydell@linaro.org>
When there is no active interrupts in the GIC, a read to the C_RPR
register should return the value of the "Idle priority", which is either
the maximum value an IRQ priority field can be set to, or 0xff.
Since the QEMU GIC model implements all the 8 priority bits, the Idle
priority is 0xff.
Internally, when there is no active interrupt, the running priority
value is 0x100. The gic_get_running_priority function returns an uint8_t
and thus, truncate this value to 0x00 when returning it. This is wrong since
a value of 0x00 correspond to the maximum possible priority.
This commit fixes the returned value when the internal value is 0x100.
Note that it is correct for the Non-Secure view to return 0xff even
though from the NS world point of view, only 7 priority bits are
implemented. The specification states that the Idle priority can be 0xff
even when not all the 8 priority bits are implemented. This has been
verified against a real GICv2 hardware on a Xilinx ZynqMP based board.
Regarding the ARM11MPCore version of the GIC, the specification is not
clear on that point, so this commit does not alter its behavior.

In the GIC, when an IRQ is acknowledged, its state goes from "pending"
to:
- "active" if the corresponding IRQ pin has been de-asserted
- "active and pending" otherwise.
The GICv2 manual states that when a IRQ becomes active (or active and
pending), the GIC should either signal another (higher priority) IRQ to
the CPU if there is one, or de-assert the CPU IRQ pin.
The current implementation of the GIC in QEMU does not check if the
IRQ is already active when looking for pending interrupts with
sufficient priority in gic_update(). This can lead to signaling an
interrupt that is already active.
This usually happens when splitting priority drop and interrupt
deactivation. On priority drop, the IRQ stays active until deactivation.
If it becomes pending again, chances are that it will be incorrectly
selected as best_irq in gic_update().
This commit fixes this by checking if the IRQ is not already active when
looking for best_irq in gic_update().
Note that regarding the ARM11MPCore GIC version, the corresponding
manual is not clear on that point, but it has has no priority
drop/interrupt deactivation separation, so this case should not happen.

lead to disabling the receive function in the i.MX FEC/ENET device.
This patch change the place where the register update is done so that the

With the LEON3 IRQ controller IRQs can be acknowledged 2 ways:
* Explicitly by software writing to the CLEAR_OFFSET register
* Implicitly when the procesor is done running the trap handler attached
to the IRQ.
The actual IRQMP code only allows the implicit processor triggered IRQ ack.
If software write explicitly to the CLEAR_OFFSET register, this will clear
the pending bit in the register value but this will not lower the ongoing
raised IRQ with the processor. The IRQ will be kept raised to the LEON
processor until the related trap handler is run and the processor implicitly
ack the interrupt. So with the actual IRQMP code trap handler have to be run
even if the software has already done its job by clearing the pending bit.
This feature has been tested on another LEON3 simulator (tsim_leon3 from
Gaisler) and it turns out that the Qemu implementation is not equivalent to
the tsim one. In tsim, if software does clear a pending interrupt before
the related interrupt handler is triggered the said interrupt handler will
not be called.
This patch brings the Qemu IRQMP implementation in line with the tsim
implementation by allowing IRQ to be acknowledged by software only.

Fix storage attribute migration so that it does not fail for guests
with more than a few GB of RAM.
With such guests, the index in the buffer would go out of bounds,
usually by large amounts, thus receiving -EFAULT from the kernel.
Migration itself would be successful, but storage attributes would then
not be migrated completely.
This patch fixes the out of bounds access, and thus migration of all
storage attributes when the guest have large amounts of memory.

Commit 51f84465dd changed the compatility mode setting logic:
- machine reset only sets compatibility mode for the boot CPU
- compatibility mode is set for other CPUs when they are put online
by the guest with the "start-cpu" RTAS call
This causes a regression for machines started with max-compat-cpu:
the device tree nodes related to secondary CPU cores contain wrong
"cpu-version" and "ibm,pa-features" values, as shown below.
Guest started on a POWER8 host with:
-smp cores=2 -machine pseries,max-cpu-compat=compat7
ibm,pa-features = [18 00 f6 3f c7 c0 80 f0 80 00
00 00 00 00 00 00 00 00 80 00 80 00 80 00 00 00];
cpu-version = <0x4d0200>;
^^^
second CPU core
ibm,pa-features = <0x600f63f 0xc70080c0>;
cpu-version = <0xf000003>;
^^^
boot CPU core
The second core is advertised in raw POWER8 mode. This happens because
CAS assumes all CPUs to have the same compatibility mode. Since the
boot CPU already has the requested compatibility mode, the CAS code
does not set it for the secondary one, and exposes the bogus device
tree properties in in the CAS response to the guest.
A similar situation is observed when hot-plugging a CPU core. The
related device tree properties are generated and exposed to guest
with the "ibm,configure-connector" RTAS before "start-cpu" is called.
The CPU core is advertised to the guest in raw mode as well.
It both cases, it boils down to the fact that "start-cpu" happens too
late. This can be fixed globally by propagating the compatibility mode
of the boot CPU to the other CPUs during reset. For this to work, the
compatibility mode of the boot CPU must be set before the machine code
actually resets all CPUs.
It is not needed to set the compatibility mode in "start-cpu" anymore,
so the code is dropped.

before machine_init() is called and the 1st cpu is created,
so that mgmt might be able to call it and use output to set
numa mapping.
Use MachineClass::possible_cpu_arch_ids() callback to set
cpu type info, along with the rest of possible cpu properties,
to let machine define which cpu type* will be used.
* for SPAPR it will be a spapr core type and for ARM/s390x/x86
a respective descendant of CPUClass.
Move parse_numa_opts() in vl.c after cpu_model is parsed into
cpu_type so that possible_cpu_arch_ids() would know which
cpu_type to use during layout initialization.

Currently the only vNVDIMM backend can guarantee the guest write
persistence is device DAX on Linux, because no host-side kernel cache
is involved in the guest access to it. The approach to detect whether
the backend is device DAX needs to access sysfs, which may not work
with SELinux.
Instead, we add the 'unarmed' option to device 'nvdimm', so that users
or management utils, which have enough knowledge about the backend,
can control the unarmed flag in guest ACPI NFIT via this option. The
guest Linux NVDIMM driver, for example, will mark the corresponding
vNVDIMM device read-only if the unarmed flag in guest NFIT is set.
The default value of 'unarmed' option is 'off' in order to keep the
backwards compatibility.

The qdev_unplug() function contains a g_assert(hotplug_ctrl) statement,
so QEMU crashes when the user tries to device_add + device_del a device
that does not have a corresponding hotplug controller. This could be
provoked for a couple of devices in the past (see commit 4c93950659
or 84ebd3e8c7 for example), and can currently for example also be
triggered like this:
$ s390x-softmmu/qemu-system-s390x -M none -nographic
QEMU 2.10.50 monitor - type 'help' for more information
(qemu) device_add qemu-s390x-cpu,id=x
(qemu) device_del x
**
ERROR:qemu/qdev-monitor.c:872:qdev_unplug: assertion failed: (hotplug_ctrl)
Aborted (core dumped)
So devices clearly need a hotplug controller when they should be usable
with device_add.
The code in qdev_device_add() already checks whether the bus has a proper
hotplug controller, but for devices that do not have a corresponding bus,
there is no appropriate check available yet. In that case we should check
whether the machine itself provides a suitable hotplug controller and
refuse to plug the device if none is available.

The only user-creatable sysbus devices in qemu-system-x86_64 are
amd-iommu, intel-iommu, and xen-backend. xen-backend is handled
by xen_set_dynamic_sysbus(), so we only need to add amd-iommu and
intel-iommu.

There's no need to make the machine allow every possible sysbus
device. We can now just add xen-sysdev to the allowed list.
