tcg/tci: Move stack bounds check to compile-time · 53f40556


The existing check was incomplete:
(1) Only applied to two of the 7 stores, and not to the loads at all.
(2) Only checked the upper, but not the lower bound of the stack.

Doing this at compile time means that we don't need to do it
at runtime as well.

which took two register numbers and a 64-bit version which was a

For a 64-bit TCI, the upper bits of a 32-bit operation are
undefined (much like a native ppc64 32-bit operation).  It

tcg/tci: Make tci_tb_ptr thread-local · 13e71f08

Richard Henderson authored 4 years ago


Each thread must have its own pc, even under TCI.

Remove the GETPC ifdef, because GETPC is always available for
helpers, and thus is always required.  Move the assignment
under INDEX_op_call, because the value is only visible when
we make a call to a helper function.

Fixes INDEX_op_rotli_vec for aarch64 host, where the 3rd
argument is an integer, not a temporary, which now tickles
an assert added in e89b28a6.

Previously, the value computed into v2 would be garbage for
rotli_vec, but as the value was unused it caused no harm.

exec/cpu-defs: Remove TCG backends dependency · 37c8c531

Philippe Mathieu-Daudé authored 4 years ago


"exec/cpu-defs.h" contains generic CPU definitions for the
TCG frontends (mostly related to TLB). TCG backends definitions
aren't relevant here.

See tcg/README description:

  4) Backend

  tcg-target.h contains the target specific definitions. tcg-target.c.inc
  contains the target specific code; it is #included by tcg/tcg.c, rather
  than being a standalone C file.

So far only "tcg/tcg.h" requires these headers.

Remove the "target-tcg.h" header dependency on TCG frontends, so we
don't have to rebuild all frontends when hacking a single backend.

tcg/s390: Fix compare instruction from extended-immediate facility · 8e43c5a1

Philippe Mathieu-Daudé authored 4 years ago


The code is currently comparing c2 to the type promotion of
uint32_t and int32_t. That is, the conversion rules are as:

  (common_type) c2 == (common_type) (uint32_t)
                        (is_unsigned
                        ? (uint32_t)c2
                        : (uint32_t)(int32_t)c2)

In the signed case we lose the desired sign extensions because
of the argument promotion rules of the ternary operator.

Solve the problem by doing the round-trip parsing through the
intermediate type and back to the desired common type (all at
one expression).

acpi: Permit OEM ID and OEM table ID fields to be changed · 602b4582

Marian Postevca authored 4 years ago


Qemu's ACPI table generation sets the fields OEM ID and OEM table ID
to "BOCHS " and "BXPCxxxx" where "xxxx" is replaced by the ACPI
table name.

Some games like Red Dead Redemption 2 seem to check the ACPI OEM ID
and OEM table ID for the strings "BOCHS" and "BXPC" and if they are
found, the game crashes(this may be an intentional detection
mechanism to prevent playing the game in a virtualized environment).

This patch allows you to override these default values.

The feature can be used in this manner:
qemu -machine oem-id=ABCDEF,oem-table-id=GHIJKLMN

The oem-id string can be up to 6 bytes in size, and the
oem-table-id string can be up to 8 bytes in size. If the string are
smaller than their respective sizes they will be padded with space.
If either of these parameters is not set, the current default values
will be used for the one missing.

Note that the the OEM Table ID field will not be extended with the
name of the table, but will use either the default name or the user
provided one.

This does not affect the -acpitable option (for user-defined ACPI
tables), which has precedence over -machine option.

vhost: Unbreak SMMU and virtio-iommu on dev-iotlb support · 958ec334

Peter Xu authored 4 years ago

Previous work on dev-iotlb message broke vhost on either SMMU or virtio-iommu
since dev-iotlb (or PCIe ATS) is not yet supported for those archs.

An initial idea is that we can let IOMMU to export this information to vhost so
that vhost would know whether the vIOMMU would support dev-iotlb, then vhost
can conditionally register to dev-iotlb or the old iotlb way. We can work
based on some previous patch to introduce PCIIOMMUOps as Yi Liu proposed [1].

However it's not as easy as I thought since vhost_iommu_region_add() does not
have a PCIDevice context at all since it's completely a backend. It seems
non-trivial to pass over a PCI device to the backend during init. E.g. when
the IOMMU notifier registered hdev->vdev is still NULL.

To make the fix smaller and easier, this patch goes the other way to leverage
the flag_changed() hook of vIOMMUs so that SMMU and virtio-iommu can trap the
dev-iotlb registration and fail it. Then vhost could try the fallback solution
as using UNMAP invalidation for it's translations.

virtio: Add corresponding memory_listener_unregister to unrealize · f6ab64c0

Eugenio Pérez authored 4 years ago

Address space is destroyed without proper removal of its listeners with
current code. They are expected to be removed in
virtio_device_instance_finalize [1], but qemu calls it through
object_deinit, after address_space_destroy call through
device_set_realized [2].

Move it to virtio_device_unrealize, called before device_set_realized
[3] and making it symmetric with memory_listener_register in
virtio_device_realize.

v2: Delete no-op call of virtio_device_instance_finalize.
    Add backtraces.

virtio-mmio: fix guest kernel crash with SHM regions · 2d9e7d4c

Laurent Vivier authored 4 years ago


In the kernel, virtio_gpu_init() uses virtio_get_shm_region()
since
commit 6076a9711dc5 ("drm/virtio: implement blob resources: probe for host visible region")
but vm_get_shm_region() unconditionally uses VIRTIO_MMIO_SHM_SEL to
get the address and the length of the region.

commit 38e895487afc ("virtio: Implement get_shm_region for MMIO transport"

As this is not implemented in QEMU, address and length are 0 and passed
as is to devm_request_mem_region() that triggers a crash:

  [drm:virtio_gpu_init] *ERROR* Could not reserve host visible region
  Unable to handle kernel NULL pointer dereference at virtual address (ptrval)

According to the comments in the kernel, a non existent shared region
has a length of (u64)-1.

This is what we return now with this patch to disable the region.

virtio: move 'use-disabled-flag' property to hw_compat_4_2 · c126b4c5

Stefano Garzarella authored 4 years ago


Commit 9d7bd082 introduced a new 'use-disabled-flag' property
set to true by default.
To allow the migration, we set this property to false in the hw_compat,
but in the wrong place (hw_compat_4_1).

Since commit 9d7bd082 was released with QEMU 5.0, we move
'use-disabled-flag' property to hw_compat_4_2, so 4.2 machine types
will have the pre-patch behavior and the migration can work.

The issue was discovered with vhost-vsock device and 4.2 machine
type without running any kernel in the VM:
    $ qemu-4.2 -M pc-q35-4.2,accel=kvm \
        -device vhost-vsock-pci,guest-cid=4 \
        -monitor stdio -incoming tcp:0:3333

    $ qemu-5.2 -M pc-q35-4.2,accel=kvm \
        -device vhost-vsock-pci,guest-cid=3 \
        -monitor stdio
    (qemu) migrate -d tcp:0:3333

    # qemu-4.2 output
    qemu-system-x86_64: Failed to load virtio-vhost_vsock:virtio
    qemu-system-x86_64: error while loading state for instance 0x0 of device '0000:00:03.0/virtio-vhost_vsock'
    qemu-system-x86_64: load of migration failed: No such file or directory

pci: add romsize property · 08b1df8f

Paolo Bonzini authored 4 years ago


This property can be useful for distros to set up known-good ROM sizes for
migration purposes.  The VM will fail to start if the ROM is too large,
and migration compatibility will not be broken if the ROM is too small.

Note that even though romsize is a uint32_t, it has to be between 1
(because empty ROM files are not accepted, and romsize must be greater
than the file) and 2^31 (because values above are not powers of two and
are rejected).

pci: reject too large ROMs · 7c16b5bb

Paolo Bonzini authored 4 years ago


get_image_size() returns an int64_t, which pci_add_option_rom() assigns
to an "int" without any range checking.  A 32-bit BAR could be up to
2 GiB in size, so reject anything above it.  In order to accomodate
a rounded-up size of 2 GiB, change pci_patch_ids's size argument
to unsigned.
