Xingang Wang 26863366b2 hw/i386/acpi-build: Add DMAR support to bypass iommu
In DMAR table, the drhd is set to cover all PCI devices when intel_iommu
is on. To support bypass iommu feature, we need to walk the PCI bus with
bypass_iommu disabled and add explicit scope data in DMAR drhd structure.

Xingang Wang 42e0f050e3 hw/arm/virt-acpi-build: Add IORT support to bypass SMMUv3
When we build IORT table with SMMUv3 and bypass iommu feature enabled,
we can no longer setup one map from RC to SMMUv3 covering the whole RIDs.
We need to walk the PCI bus and check whether the root bus will bypass
iommu, setup RC -> SMMUv3 -> ITS map for RC which will not bypass iommu.

When a SMMUv3 node exist, we setup the idmap from SMMUv3 to ITS
covering the whole RIDs, and only modify the map from RC to SMMUv3.
We build RC -> SMMUv3 -> ITS map for root bus with bypass_iommu
disabled, and build idmap from RC to ITS directly for the rest of
the whole RID space.

For example we run qemu with command line:

qemu/build/aarch64-softmmu/qemu-system-aarch64 \
 -kernel arch/arm64/boot/Image \
 -enable-kvm \
 -cpu host \
 -m 8G \

Peter Xu 7395b3e3e7 docs: Add '-device intel-iommu' entry
The parameters of intel-iommu device are non-trivial to understand.  Add an
entry for it so that people can reference to it when using.

There're actually a few more options there, but I hide them explicitly because
they shouldn't be used by normal QEMU users.

Julia Suvorova 17858a1695 hw/acpi/ich9: Set ACPI PCI hot-plug as default on Q35
Q35 has three different types of PCI devices hot-plug: PCIe Native,
SHPC Native and ACPI hot-plug. This patch changes the default choice
for cold-plugged bridges from PCIe Native to ACPI Hot-plug with
ability to use SHPC and PCIe Native for hot-plugged bridges.

This is a list of the PCIe Native hot-plug issues that led to this
change:
    * no racy behavior during boot (see 110c477c2e)
    * no delay during deleting - after the actual power off software
      must wait at least 1 second before indicating about it. This case
      is quite important for users, it even has its own bug:
          https://bugzilla.redhat.com/show_bug.cgi?id=1594168
    * no timer-based behavior - in addition to the previous example,
      the attention button has a 5-second waiting period, during which
      the operation can be canceled with a second press. While this
      looks fine for manual button control, automation will result in
      the need to queue or drop events, and the software receiving
      events in all sort of unspecified combinations of attention/power
      indicator states, which is racy and uppredictable.
    * fixes:

To return to PCIe Native hot-plug:
    -global ICH9-LPC.acpi-pci-hotplug-with-bridge-support=off

Known issue: older linux guests need the following flag
to allow hotplugged pci express devices to use io:
        -device pcie-root-port,io-reserve=4096.
io is unusual for pci express so this seems minor.
We'll fix this by a follow up patch.

Julia Suvorova 3f3cbbb236 hw/pci/pcie: Do not set HPC flag if acpihp is used
Instead of changing the hot-plug type in _OSC register, do not
set the 'Hot-Plug Capable' flag. This way guest will choose ACPI
hot-plug if it is preferred and leave the option to use SHPC with
pcie-pci-bridge.

The ability to control hot-plug for each downstream port is retained,
while 'hotplug=off' on the port means all hot-plug types are disabled.

Philippe Mathieu-Daudé b5b318608e hw/i386: Introduce X86_FW_OVMF Kconfig symbol
Introduce the X86_FW_OVMF Kconfig symbol for OVMF-specific code.
Move the OVMF-specific code from pc_sysfw.c to pc_sysfw_ovmf.c,
adding a pair of stubs.
Update MAINTAINERS to reach OVMF maintainers when these new
files are modified.

This fixes when building the microvm machine standalone:

Dov Murik 35ebc321b4 hw/i386/pc: pc_system_ovmf_table_find: Assert that flash was parsed
Add assertion in pc_system_ovmf_table_find that verifies that the flash
was indeed previously parsed (looking for the OVMF table) by
pc_system_parse_ovmf_flash.

Now pc_system_ovmf_table_find distinguishes between "no one called
pc_system_parse_ovmf_flash" (which will abort due to assertion failure)
and "the flash was parsed but no OVMF table was found, or it is invalid"
(which will return false).

Philippe Mathieu-Daudé ac0595cf6b gitlab-ci: Extract EDK2 job rules to reusable section
All jobs depending on 'docker-edk2' job must use at most all
the rules that triggers it. The simplest way to ensure that
is to always use the same rules. Extract all the rules to a
reusable section, and include this section (with the 'extends'
keyword) in both 'docker-edk2' and 'build-edk2' jobs.

The problem was introduced in commit 71920809ce ("gitlab-ci.yml:
Add jobs to build EDK2 firmware binaries"), but was revealed in
commit 1925468ddb ("docker: EDK2 build job depends on EDK2

Cai Huoqing 1bd9f1b14d vfio/pci: Add pba_offset PCI quirk for BAIDU KUNLUN AI processor
Fix pba_offset initialization value for BAIDU KUNLUN Virtual
Function device. The KUNLUN hardware returns an incorrect
value for the VF PBA offset, and add a quirk to instead
return a hardcoded value of 0xb400.

David Hildenbrand a5dba9bc05 vfio: Fix CID 1458134 in vfio_register_ram_discard_listener()
CID 1458134:  Integer handling issues  (BAD_SHIFT)
    In expression "1 << ctz64(container->pgsizes)", left shifting by more
    than 31 bits has undefined behavior.  The shift amount,
    "ctz64(container->pgsizes)", is 64.

Commit 5e3b981c33 ("vfio: Support for RamDiscardManager in the !vIOMMU
case") added an assertion that our granularity is at least as big as the
page size.

Although unlikely, we could have a page size that does not fit into
32 bit. In that case, we'd try shifting by more than 31 bit.

Let's use 1ULL instead and make sure we're not shifting by more than 63
bit by asserting that any bit in container->pgsizes is set.

Alex Bennée ba4dd2aabc tcg/plugins: enable by default for most TCG builds
Aside from a minor bloat to file size the ability to have TCG plugins
has no real impact on performance unless a plugin is actively loaded.
Even then the libempty.so plugin shows only a minor degradation in
performance caused by the extra book keeping the TCG has to do to keep
track of instructions. As it's a useful feature lets just enable it by
default and reduce our testing matrix a little.

We need to move our linker testing earlier so we can be sure we can
enable the loader module required. As we have ruled out static &
plugins in an earlier patch we can also reduce the indent a little.

Alex Bennée 2d93203998 plugins: fix-up handling of internal hostaddr for 32 bit
The compiler rightly complains when we build on 32 bit that casting
uint64_t into a void is a bad idea. We are really dealing with a host
pointer at this point so treat it as such. This does involve
a uintptr_t cast of the result of the TLB addend as we know that has
to point to the host memory.

memory access.

While we are at it clean-up the white space and style issues from the
legacy code. As we no longer do quite so much needless memory access
we can also remove the hexagon timeout hack.
