This patch correct calculation formula of PHY timing.
The spec define HS-PREPARE should be from 40ns+4*UI(44ns) to
85ns+6*UI(91ns). But current duration is 88ns and is near the boundary.
So this patch make the duration to 64ns so it is near the safe range.

Changes
The table of primary plane formats wasn't sorted at all, leading to
applications picking our least desirable formats by defaults.
Sort the primary plane formats according to our order of preference.
Nice side-effect of this change is that it makes IGT's kms_atomic
plane-invalid-params pass
vmwgfx didn't have support for vblank or crc generation which made it
impossible to use a large number of IGT tests to properly test DRM
functionality in the driver.
This series add virtual vblank and crc generation support, which allows
running most of IGT and immediately helped fix a number of
The conditional was supposed to prevent enabling of a crtc state
without a set primary plane. Accidently it also prevented disabling
crtc state with a set primary plane. Neither is correct.
Fix the conditional and just driver-warn when a crtc state has been
enabled without a primary plane which
vmwgfx never supported prime import of external buffers. Furthermore the
driver exposes two different objects to userspace: vmw_surface's and
gem buffers but prime import/export only worked with vmw_surfaces.
Because gem buffers are used through the dumb_buffer interface this meant
that the
crc checksums are used to validate the output. Normally they're part
of the actual display hardware but on virtual stack there's nothing
to automatically generate them.
Implement crc generation for the vmwgfx stack. This works only on
screen targets, where it's possibly to easily make sure that
By default vmwgfx doesn't support vblanking or crc generation which
makes it impossible to use various IGT tests to validate vmwgfx.
Implement virtual kernel mode setting, which is mainly related to
simulated vblank support.
Code is very similar to amd's vkms and the vkms module itself, except
Hi Linus,
Looks like everyone woke up after holidays, this weeks pull has a
bunch of stuff all over, 2 weeks worth of amdgpu is a lot of it, then
i915/xe have a few, a bunch of msm fixes, then some scattered driver
fixes.
I expect things will settle down for rc5.
Dave.

The patch is based on the mainline tree. Should I have sent it directly to
Linus then?
I'm relatively new here and therefore only sent it to the corresponding mailing

Hi Dave and Sima,
Please pull the drm-xe-fixes for this week targeting v6.9-rc4.
Just some trivial fixes, mostly from code analysis. The last one
doesn't trigger any issue for now since the register is not used for
mmio. I decided to include it, because it would be a silent prereq of

remove the unsed the paramter in the function
ttm_bo_bounce_temp_buffer and ttm_bo_add_move_fence.
V2:rebase the patch on top of drm-misc-next (Christian)
And pushed to drm-misc-next.
Thanks,

When Output Resource (dcb->or) value is assigned in
fabricate_dcb_output(), there may be out of bounds access to
dac_users array in case dcb->or is zero because ffs(dcb->or) is
used as index there.
The 'or' argument of fabricate_dcb_output() must be interpreted as a
number of bit to set, not

Using memfd_pin_folios() will ensure that the pages are pinned
correctly using FOLL_PIN. And, this also ensures that we don't
accidentally break features such as memory hotunplug as it would
not allow pinning pages in the movable zone.
Using this new API also simplifies the code as we no longer
Add VM_PFNMAP to vm_flags in the mmap handler to ensure that
the mappings would be managed without using struct page.
And, in the vm_fault handler, use vmf_insert_pfn to share the
page's pfn to userspace instead of directly sharing the page
(via struct page *).

This helper is the folio equivalent of check_and_migrate_movable_pages().
Therefore, all the rules that apply to check_and_migrate_movable_pages()
also apply to this one as well. Currently, this helper is only used by

This patch also includes changes to rename and convert the
These helpers are the folio versions of unpin_user_page/unpin_user_pages.
They are currently only useful for unpinning folios pinned by
memfd_pin_folios() or other associated routines. However, they could
find new uses in the future, when more and more folio-only helpers
are added to GUP.

Since the memfd pages associated with a udmabuf may be migrated
as part of udmabuf create, we need to verify the data coherency
after successful migration. The new tests added in this patch try
to do just that using 4k sized pages and also 2 MB sized huge
pages for the memfd.
Successful
For drivers that would like to longterm-pin the folios associated
with a memfd, the memfd_pin_folios() API provides an option to
not only pin the folios via FOLL_PIN but also to check and migrate
them if they reside in movable zone or CMA block. This API
currently works with memfds but it should
A user or admin can configure a VMM (Qemu) Guest's memory to be
backed by hugetlb pages for various reasons. However, a Guest OS
would still allocate (and pin) buffers that are backed by regular
4k sized pages. In order to map these buffers and create dma-bufs
for them on the Host, we first need
Currently, some drivers (e.g, Udmabuf) that want to longterm-pin
the pages/folios associated with a memfd, do so by simply taking a
reference on them. This is not desirable because the pages/folios
may reside in Movable zone or CMA block.
Therefore, having drivers use memfd_pin_folios() API
