c5b9077eca drm/i915/gvt: use drm->debugfs_root for creating debugfs files
Since commit 0b30d57aca ("drm/debugfs: rework debugfs directory
creation v5") we should be using drm->debugfs_root instead of
minor->debugfs_root for creating debugfs files.

Since commit 0b30d57aca ("drm/debugfs: rework debugfs directory
creation v5") we should be using drm->debugfs_root instead of
minor->debugfs_root for creating debugfs files.

As a rule of thumb, use a local variable when there are two or more
uses, otherwise just have the single reference inline.

Drop drm/drm_file.h include where possible.

d9d87d90cc treewide: rename GPIO set callbacks back to their original names
The conversion of all GPIO drivers to using the .set_rv() and
.set_multiple_rv() callbacks from struct gpio_chip (which - unlike their
predecessors - return an integer and allow the controller drivers to
indicate failures to users) is now complete and the legacy ones have
been removed. Rename the new callbacks back to their original names in
one sweeping change.

2e58401a24 drm/amdkfd: Destroy KFD debugfs after destroy KFD wq
Since KFD proc content was moved to kernel debugfs, we can't destroy KFD

to kfd_debugfs_fini to fix a kernel NULL pointer problem. It happens

kfd_process_destroy_wq calls kfd_debugfs_remove_process. This line

ad69d62588 drm/xe/pf: Program LMTT directory pointer on all GTs within a tile
Previously, the LMTT directory pointer was only programmed for primary GT
within a tile. However, to ensure correct Local Memory access by VFs,
the LMTT configuration must be programmed on all GTs within the tile.
Lets program the LMTT directory pointer on every GT of the tile
to guarantee proper LMEM access across all GTs on VFs.

The patch is based on the driver parts of the patchset at Link:
below, which missed converting the radeon driver.

Due to the absence of this change in the patchset at Link:, after the
Fixed: commit below, radeon_framebuffer_init() ->
drm_helper_mode_fill_fb_struct() set drm_framebuffer::format incorrectly
to NULL, which lead to the !fb->format WARN() in drm_framebuffer_init()
and causing framebuffer creation to fail. This patch fixes both of these
issues.

v2: Amend the commit log mentioning the functional issues the patch
    fixes. (Tomi)

979f61633d drm/xe/svm: Migrate folios when possible
The DMA mapping can now correspond to a folio (order > 0), so move
the iterator by the number of pages in the folio in order to migrate
all pages at once.

This requires forcing contiguous memory for SVM BOs, which greatly
simplifies the code and enables 2MB device page support, allowing a
major performance improvement. Negative effects like extra eviction
are unlikely as SVM BOs have a maximal size of 2MB.

v2:
- Improve commit message (Matthew Brost)
- Fix increment, chunk, assert match (Matthew Brost)

321d420325 drm/xe/migrate: Populate struct drm_pagemap_addr array
Workaround to ensure all addresses are populated in the array as
this is expected when creating the copy batch. This is required
because the migrate layer does not support 2MB GPU pages yet. A
proper fix will come in a follow-up.

ddeda61360 drm/pagemap: Allocate folios when possible
If the order is greater than zero, allocate a folio when populating the
RAM PFNs instead of allocating individual pages one after the other. For
example if 2MB folios are used instead of 4KB pages, this reduces the
number of calls to the allocation API by 512.

v2:
- Use page order instead of extra argument (Matthew Brost)
- Allocate with folio_alloc() (Matthew Brost)
- Loop for mpages and free_pages based on order (Matthew Brost)

v3:
- Fix loops in drm_pagemap_migrate_populate_ram_pfn() (Matthew Brost)

v4:
- Use folio_trylock(), set local variable to NULL (Matthew Brost)

d755ff6063 drm/pagemap: DMA map folios when possible
If the page is part of a folio, DMA map the whole folio at once instead of
mapping individual pages one after the other. For example if 2MB folios
are used instead of 4KB pages, this reduces the number of DMA mappings by
512.

The folio order (and consequently, the size) is persisted in the struct
drm_pagemap_device_addr to be available at the time of unmapping.

v2:
- Initialize order variable (Matthew Brost)
- Set proto and dir for completeness (Matthew Brost)
- Do not populate drm_pagemap_addr, document it (Matthew Brost)
- Add and use macro NR_PAGES(order) (Matthew Brost)

f35a6cdf8a drm/pagemap: Use struct drm_pagemap_addr in mapping and copy functions
This struct embeds more information than just the DMA address. This will
help later to support folio orders greater than zero. At this point, there
is no functional change as the only struct member used is addr.

In Xe, adapt to the new drm_gpusvm_devmem_ops type signatures using struct
drm_pagemap_addr, as well as the internal xe SVM functions implementing
those operations. The use of this struct is propagated to xe_migrate as it
makes indexed accesses to the next DMA address but they are no longer
contiguous.

v2:
- Rename drm_pagemap_device_addr to drm_pagemap_addr (Matthew Brost)
- Squash with patch for Xe (Matthew Brost)
- Set proto and dir for completeness (Matthew Brost)
- Assess DMA map protocol (Matthew Brost)
