vfio/igd: Fix incorrect error propagation in vfio_pci_igd_opregion_detect()

In vfio_pci_igd_opregion_detect(), errp will be set when the device does
not have OpRegion or is hotplugged. This errp will be propagated to
pci_qdev_realize(), which interprets it as failure, causing unexpected
termination on devices without OpRegion like SR-IOV VFs or discrete
GPUs. Fix it by not setting errp in vfio_pci_igd_opregion_detect().

This patch also checks if the device has OpRegion before hotplug status
to prevent unwanted warning messages on non-IGD devices.

vfio: add region info cache

Instead of requesting region information on demand with
VFIO_DEVICE_GET_REGION_INFO, maintain a cache: this will become
necessary for performance for vfio-user, where this call becomes a
message over the control socket, so is of higher overhead than the
traditional path.

We will also need it to generalize region accesses, as that means we
can't use ->config_offset for configuration space accesses, but must
look up the region offset (if relevant) each time.

vfio/igd: Remove generation limitation for IGD passthrough

Starting from Intel Core Ultra Series (Meteor Lake), Data Stolen Memory
has became a part of LMEMBAR (MMIO BAR2) [1][2], meaning that BDSM and
GGC register quirks are no longer needed on these platforms.

To support Meteor/Arrow/Lunar Lake and future IGD devices, remove the
generation limitation in IGD passthrough, and apply BDSM and GGC quirks
only to known Gen6-12 devices.

Check the vendor and device ID on GVT-g mdev to ensure it is a supported
device [1]. This extra check is required for automatically enabling

Note that Cherryview and Gemini Lake are marked as supported here since
current code cannot distinguish them with other Gen8 and Gen9 devices.
Since mdev cannot be created on these devices, this has no functional
impact.

ASLS register represents the base address of OpRegion, and it is
programmed with HPA. In IGD passthrough scenario, it needs to be
reprogrammed with GPA by guest firmware. To prevent guest accessing
wrong memory range, ASLS should always be emulated and cleared.

In GVT-g scenario, emulating ASLS is unnecessary as access is handled
by kvmgt backend [1].

vfio/igd: Fix broken KVMGT OpRegion support

The KVMGT/GVT-g vGPU also exposes OpRegion. But unlike IGD passthrough,
it only needs the OpRegion quirk. A previous change moved x-igd-opregion
handling to config quirk breaks KVMGT functionality as it brings extra
checks and applied other quirks. Here we check if the device is mdev
(KVMGT) or not (passthrough), and then applies corresponding quirks.

As before, users must manually specify x-igd-opregion=on to enable it
on KVMGT devices. In the future, we may check the VID/DID and enable
OpRegion automatically.

vfio/igd: Decouple common quirks from legacy mode

So far, IGD-specific quirks all require enabling legacy mode, which is
toggled by assigning IGD to 00:02.0. However, some quirks, like the BDSM
and GGC register quirks, should be applied to all supported IGD devices.
A new config option, x-igd-legacy-mode=[on|off|auto], is introduced to
control the legacy mode only quirks. The default value is "auto", which
keeps current behavior that enables legacy mode implicitly and continues
on error when all following conditions are met.
* Machine type is i440fx
* IGD device is at guest BDF 00:02.0

If any one of the conditions above is not met, the default behavior is
equivalent to "off", QEMU will fail immediately if any error occurs.

Users can also use "on" to force enabling legacy mode. It checks if all
the conditions above are met and set up legacy mode. QEMU will also fail
immediately on error in this case.

Additionally, the hotplug check in legacy mode is removed as hotplugging
IGD device is never supported, and it will be checked when enabling the
OpRegion quirk.

it into the newly introduced vfio_config_quirk_setup. There is no
functional change in this commit.

For now, to align with current legacy mode behavior, it returns and
proceeds on error. Later it will fail on error after decoupling the
quirks from legacy mode.
