Thomas Huth da969774af hw/arm: Remove the deprecated xlnx-ep108 machine
It has been marked as deprecated since QEMU v2.11, so it is time to
remove this now. The xlnx-zcu102 machine is very much the same and
can be used as a replacement instead.

Cédric Le Goater 8576b12df7 ftgmac100: add IEEE 802.1Q VLAN support
The ftgmac100 NIC supports VLAN tag insertion and the MAC engine also
has a control to remove VLAN tags from received packets.

The VLAN control bits and VLAN tag information are contained in the
second word of the transmit and receive descriptors. The Insert VLAN
bit and the VLAN Tag available bit are only valid in the first segment
of the packet.

Shannon Zhao 910e204841 arm_gicv3_kvm: kvm_dist_get/put: skip the registers banked by GICR
While we skip the GIC_INTERNAL irqs, we don't change the register offset
accordingly. This will overlap the GICR registers value and leave the
last GIC_INTERNAL irq's registers out of update.

Fix this by skipping the registers banked by GICR.

Also for migration compatibility if the migration source (old version
qemu) doesn't send gicd_no_migration_shift_bug = 1 to destination, then
we shift the data of PPI to get the right data for SPI.

Commit a9994687cb ("vfio/display: core & wireup") added display
support to vfio-pci with the default being "auto", which breaks
existing VMs when the vGPU requires GL support but had no previous
requirement for a GL compatible configuration.  "Off" is the safer
default as we impose no new requirements to VM configurations.

Alex Williamson 2b1dbd0d72 vfio/quirks: Enable ioeventfd quirks to be handled by vfio directly
With vfio ioeventfd support, we can program vfio-pci to perform a
specified BAR write when an eventfd is triggered.  This allows the
KVM ioeventfd to be wired directly to vfio-pci, entirely avoiding
userspace handling for these events.  On the same micro-benchmark
where the ioeventfd got us to almost 90% of performance versus
disabling the GeForce quirks, this gets us to within 95%.

Alex Williamson c958c51d2e vfio/quirks: ioeventfd quirk acceleration
The NVIDIA BAR0 quirks virtualize the PCI config space mirrors found
in device MMIO space.  Normally PCI config space is considered a slow
path and further optimization is unnecessary, however NVIDIA uses a
register here to enable the MSI interrupt to re-trigger.  Exiting to
QEMU for this MSI-ACK handling can therefore rate limit our interrupt
handling.  Fortunately the MSI-ACK write is easily detected since the
quirk MemoryRegion otherwise has very few accesses, so simply looking
for consecutive writes with the same data is sufficient, in this case
10 consecutive writes with the same data and size is arbitrarily
chosen.  We configure the KVM ioeventfd with data match, so there's
no risk of triggering for the wrong data or size, but we do risk that
pathological driver behavior might consume all of QEMU's file
descriptors, so we cap ourselves to 10 ioeventfds for this purpose.

In support of the above, generic ioeventfd infrastructure is added
for vfio quirks.  This automatically initializes an ioeventfd list
per quirk, disables and frees ioeventfds on exit, and allows
ioeventfds marked as dynamic to be dropped on device reset.  The
rationale for this latter feature is that useful ioeventfds may
depend on specific driver behavior and since we necessarily place a
cap on our use of ioeventfds, a machine reset is a reasonable point
at which to assume a new driver and re-profile.

Xiao Guangrong f548222c24 migration: introduce decompress-error-check
QEMU 3.0 enables strict check for compression & decompression to
make the migration more robust, that depends on the source to fix
the internal design which triggers the unexpected error conditions

To make it work for migrating old version QEMU to 2.13 QEMU, we
introduce this parameter to disable the error check on the
destination which is the default behavior of the machine type
which is older than 2.13, alternately, the strict check can be
enabled explicitly as followings:
      -M pc-q35-2.11 -global migration.decompress-error-check=true

Corey Minyard 7e57b82ec3 ipmi: Use proper struct reference for KCS vmstate
The vmstate for isa_ipmi_kcs was referencing into the kcs structure,
instead create a kcs structure separate and use that.

There were also some issues in the state transfer.  The inlen field
was not being transferred, so if a transaction was in process during
the transfer it would be messed up.  And the use_irq field was
transferred, but that should come from the configuration.

To fix this, the new VMS_VSTRUCT macros are used so the exact
version of the structure can be specified, depending on what
version was being received.  So an upgrade should work for KCS.

Paul Durrant dfb6578d69 xen-hvm: stop faking I/O to access PCI config space
This patch removes the current hackery where IOREQ_TYPE_PCI_CONFIG
requests are handled by faking PIO to 0xcf8 and 0xcfc and replaces it
with direct calls to pci_host_config_read/write_common().
Doing so necessitates mapping BDFs to PCIDevices but maintaining a simple
QLIST in xen_device_realize/unrealize() will suffice.

NOTE: whilst config space accesses are currently limited to
      PCI_CONFIG_SPACE_SIZE, this patch paves the way to increasing the
      limit to PCIE_CONFIG_SPACE_SIZE when Xen gains the ability to
      emulate MCFG table accesses.

Xen 4.11 has a new API to directly map guest resources. Among the resources

This patch modifies QEMU to attempt to use the new API should it exist,

Igor Druzhinin 04a8f72e87 xen/hvm: correct reporting of modified memory under physmap during migration
When global_log_dirty is enabled VRAM modification tracking never
worked correctly. The address that is passed to xen_hvm_modified_memory()
is not the effective PFN but RAM block address which is not the same
for VRAM.

We need to make a translation for this address into PFN using
physmap. Since there is no way to access physmap properly inside
xen_hvm_modified_memory() let's make it a global structure.

Igor Mammedov 60b8fe49cc arm: fix qemu crash on startup with -bios option
When QEMU is started with following CLI
 -machine virt,gic-version=3,accel=kvm -cpu host -bios AAVMF_CODE.fd
it crashes with abort at
 accel/kvm/kvm-all.c:2164:
 KVM_SET_DEVICE_ATTR failed: Group 6 attr 0x000000000000c665: Invalid argument

Which is caused by implicit dependency of kvm_arm_gicv3_reset() on
arm_gicv3_icc_reset() where the later is called by CPU reset
reset callback.

However commit:
 3b77f6c arm/boot: split load_dtb() from arm_load_kernel()
broke CPU reset callback registration in case

  arm_load_kernel()
      ...
      if (!info->kernel_filename || info->firmware_loaded)

branch is taken, i.e. it's sufficient to provide a firmware
or do not provide kernel on CLI to skip cpu reset callback
registration, where before offending commit the callback
has been registered unconditionally.

Fix it by registering the callback right at the beginning of
arm_load_kernel() unconditionally instead of doing it at the end.

NOTE:
 we probably should eliminate that dependency anyways as well as
 separate arch CPU reset parts from arm_load_kernel() into CPU
 itself, but that refactoring that I probably would have to do
 anyways later for CPU hotplug to work.

Extend the TPM emulator backend device with state migration support.

The external TPM emulator 'swtpm' provides a protocol over
its control channel to retrieve its state blobs. We implement
functions for getting and setting the different state blobs.
In case the setting of the state blobs fails, we return a
negative errno code to fail the start of the VM.

Since we have an external TPM emulator, we need to make sure
that we do not migrate the state for as long as it is busy
processing a request. We need to wait for notification that
the request has completed processing.

Gerd Hoffmann 765c942908 hw/display: add new bochs-display device
After writing up the virtual mdev device emulating a display supporting
the bochs vbe dispi interface (mbochs.ko) and seeing how simple it
actually is I've figured that would be useful for qemu too.

So, here it is, -device bochs-display.  It is basically -device VGA
without legacy vga emulation.  PCI bar 0 is the framebuffer, PCI bar 2
is mmio with the registers.  The vga registers are simply not there
though, neither in the legacy ioport location nor in the mmio bar.
Consequently it is PCI class DISPLAY_OTHER not DISPLAY_VGA.

So there is no text mode emulation, no weird video modes (planar,
256color palette), no memory window at 0xa0000.  Just a linear
framebuffer in the pci memory bar.  And the amount of code to emulate
this (and therefore the attack surface) is an order of magnitude smaller
when compared to vga emulation.

Compatibility wise it works with OVMF (latest git master).
The bochs-drm.ko linux kernel module can handle it just fine too.
So UEFI guests should not see any functional difference to VGA.

Create a new header file, move the bochs vbe dispi interface
defines to it, so they can be used outside vga code.

Gerd Hoffmann a89fe6c329 vga: catch depth 0
depth == 0 is used to indicate 256 color modes.  Our region calculation
goes wrong in that case.  So detect that and just take the safe code
path we already have for the wraparound case.

While being at it also catch depth == 15 (where our region size
calculation goes wrong too).  And make the comment more verbose,
explaining what is going on here.

Without this windows guest install might trigger an assert due to trying
to check dirty bitmap outside the snapshot region.
