This patch series are aim to refine the IGD stolen memory support in QEMU.

Some features of Intel HW relies on the stolen memory to work, but some of
registers used to indicate the base address of stolen memory can only be
programmed once after system is powered-up. This will cause problems if
the base of the stolen memory is changed during IGD passthrough.

The solution of this patch series is allocating a new VM dedicated memory
as "guest stolen memory" in QEMU for isolation and let the "guest stolen
memory" sits in the same PA as host.

Also it introduces Intel platform definitions and clears some old funtions
and definitions.

Zhi Wang (6):
  vfio: Add Intel platform definitions
  vfio: Setup IGD quirks earlier
  vfio: Setup IGD stolen memory
  vfio: Refine GGTT clearing
  vfio: Remove extra quirks and old definitions
  vfio: Setup IGD stolen memory under secondary mode

This patch introduces device descriptions for Intel platforms. Most of
the Intel device definitions come from i915.

Initialize IGD quirks a bit earlier since we're going to support IGD
stolen memory under both primary mode (legacy mode) and secondary mode
and we need one extra memory region from IGD quirks.

We still keep using VM dedicated memory for isolation to support IGD
stolen in the guest. Becuase of the PA of the stolen memory can not be
moved after the system is powered-up, we wish the PA of the guest stolen
memory can sit in the same PA of host. A new memory region is allocated,
and the memory region will be marked as reserved in guest E820 table.

We don't need to take care of GGMS, as the accesses to GGMS from HW bypass
IOMMU.

Clear the whole GGTT page tables after the quirk is initialized. Obtain
the total size of GGTT and the entry size of one GGTT entry from
intel_device_info().

Remove extra quirks, old definitions and functions. Once the new Intel
platform definition is introduced, and the PA of guest stolen memory
equals to the PA of host stolen memory, they are not necessary anymore.

Also setup IGD stolen memory under secondary mode as some HW functions
might need the stolen memory anyway.

This patch series are aim to refine the IGD stolen memory support in QEMU.

Some features of Intel HW relies on the stolen memory to work, but some of
registers used to indicate the base address of stolen memory can only be
programmed once after system is powered-up. This will cause problems if
the base of the stolen memory is changed during IGD passthrough.

The solution of this patch series is allocating a new VM dedicated memory
as "guest stolen memory" in QEMU for isolation and let the "guest stolen
memory" sits in the same PA as host.

Also it introduces Intel platform definitions and clears some old funtions
and definitions.

Zhi Wang (6):
  vfio: Add Intel platform definitions
  vfio: Setup IGD quirks earlier
  vfio: Setup IGD stolen memory
  vfio: Refine GGTT clearing
  vfio: Remove extra quirks and old definitions
  vfio: Setup IGD stolen memory under secondary mode

This patch introduces device descriptions for Intel platforms. Most of
the Intel device definitions come from i915.

Initialize IGD quirks a bit earlier since we're going to support IGD
stolen memory under both primary mode (legacy mode) and secondary mode
and we need one extra memory region from IGD quirks.

We still keep using VM dedicated memory for isolation to support IGD
stolen in the guest. Becuase of the PA of the stolen memory can not be
moved after the system is powered-up, we wish the PA of the guest stolen
memory can sit in the same PA of host. A new memory region is allocated,
and the memory region will be marked as reserved in guest E820 table.

We don't need to take care of GGMS, as the accesses to GGMS from HW bypass
IOMMU.

Clear the whole GGTT page tables after the quirk is initialized. Obtain
the total size of GGTT and the entry size of one GGTT entry from
intel_device_info().

Remove extra quirks, old definitions and functions. Once the new Intel
platform definition is introduced, and the PA of guest stolen memory
equals to the PA of host stolen memory, they are not necessary anymore.

Also setup IGD stolen memory under secondary mode as some HW functions
might need the stolen memory anyway.

'programmed once' suppose by BIOS. Then why would the base be changed
later?

As a RFC you need tell the whole story of the problem and your proposal.
Just one sentence is far away from the RFC purpose, e.g. people may
immediately ask whether you fake a guest stolen memory to work around
some limitation in guest driver (which e.g. only boots when observing the
presence of stolen memory) or to activate a feature which strictly uses
stolen memory (e.g. framebuffer compression). If the latter then what
matters is the real stolen memory instead of faked one, blah, blah, ...

Thanks to IGD hardware designers seeing fit to change the
implementation on a whim, this has a non-trivial future maintenance
burden.  Is Intel signing up to support this?  I would suggest being
overly explicit with where each define and function lives in the Linux
kernel so that it doesn't take a great deal of research to lift new
defines here.  Extra points if we could simply include Linux kernel
headers in a way to pick them up automatically.

Along those same lines, there's a subtle behavior change here where
igd_gen() hopes that Intel is eventually converging on a stable layout
and therefore assumes newer devices are compatible with the latest
version we know about.  That's removed here, so it seems we'll always
be trailing the latest hardware.  The comment:

> +        error_report("IGD device %s is unsupported in legacy mode, "
> +                     "try SandyBridge or newer", vdev->vbasedev.name);

is also really no longer accurate.  igd_gen() had code to match older
hardware as specifically unsupported vs only unknown (and assumed to be
supported using the newest generation we know about).  Now the unknown
device could be new or old, so suggesting SandyBridge or newer isn't
helpful advice for a user.

Why "intel-platform"?  Maybe this is subtly trying to indicate that IGD
is really a broken mix of PCI and "platform" devices since it's PCI yet
relies on various non-PCI resources, like stolen memory.  In any case,
it's a bit confusing from a vfio perspective.  Perhaps pci-igd?  Thanks,

Alex

This patch does not stand on its own, we alloc memory and setup a few
things earlier, but there are numerous returns before we get to the
next chunk below.  So the most obvious result of this patch alone is
that it introduces a memory leak.  Thanks,

:-O  So the device has access to a reserved region of host memory
regardless of the IOMMU.  Should the kernel be doing something to
save/restore that area or scrub that region before we get access to the
device?

This only needs to be 1MB aligned, not naturally aligned, right?

We discussed off-list that maybe it's an acceptable solution to waste
VM memory for stolen memory, ie. let QEMU allocate the buffer and map
it into the VM at the same address as the host.  But I'm not really
sure what problem doing that here is solving other than we don't yet
expose IGD stolen memory as a device specific region on the vfio
device.  Is that plan to add that device specific region and do an mmap
of it rather than the above memalign when available?  That way we're
only wasting the memory we're overlapping, which may not even be
allocated yet.

There are also some hotplug issues here.  A) We cannot do this for a
hot-added device, there's a test later in the code for disabling legacy
mode for hot-added devices.  B) Is it possible to do cleanup on
hot-remove or do we need to disable the ability to hot-remove IGD
devices?

The x-igd-gms option should also be removed in this patch as well as
igd_gms.  Is it possible to virtualize the size?  Is it worthwhile?

This should be moved closer to where we do the setup, this trace would
