40aeab044a drm/doc/rfc: Introduce the merge plan for the Xe driver.
Let’s establish a merge plan for Xe, by writing down clear pre-merge goals, in
order to avoid unnecessary delays.

This initial document starts with a TODO list containing items with clear and
measurable key results. Xe’s initial pull request should only be sent to
dri-devel after all the items are clearly resolved.

Since many of them involve some level of a community consensus, in many cases,
the consensus will be reached in follow-up patches to this document with more
details of the API or helpers that will be developed or modified.

Besides of the items that are highlighted in this document, it is important
to highlight that Oded, has been volunteered to give the overall ack on Xe
driver as the way to confirm that it looks good for upstream.

v2: Incorporated Daniel's feedback:
    - Do not make long-running compute a blocker.
    - Add a mention to drm-exec that that ties to vm_bind and long-running
      compute jobs. Then I also added GPUVA since I recently noticed that this
      ties also to the work Matt is doing on that front.
    - Added the devcoredump section.
    - Add the mention to Oded being volunteered for the overall ack.

v3: Reword a bit the Async VM_BIND to incorporate Daniel's feedback on ensuring
    the async vmbind consensus explicitly include Mesa, besides other kernel
    drivers.

drm/gem: Check for valid formats
Currently, drm_gem_fb_create() doesn't check if the pixel format is
supported, which can lead to the acceptance of invalid pixel formats
e.g. the acceptance of invalid modifiers. Therefore, add a check for
valid formats on drm_gem_fb_create().

Note that this check is only valid for atomic drivers, because, for
non-atomic drivers, checking drm_any_plane_has_format() is not
possible since the format list for the primary plane is fake, and we'd
therefore reject valid formats.

Adding this check to drm_gem_fb_create() will guarantee that the
igt@kms_addfb_basic@addfb25-bad-modifier IGT test passes for drivers
using this callback.

This commit is a recapture of a series sent a while ago. Initially,
I sent a patch [1] similar to this one in which I introduced the
format check to drm_gem_fb_create().

Based on the feedback on the patch, I placed the check inside
framebuffer_check() [2] so that it wouldn't be needed to hit any
driver-specific code path when the check fails. Therefore, we could
remove the check from the specific drivers (i915, amdgpu, and vmwgfx).

But, with some new feedback, it was shown that introducing this check
inside framebuffer_check() is problematic for the i915 driver [3].
For the i915 driver, in the legacy case, in which we don't get the
modifier from the userspace, i915's fb_create hook computes the right
modifier, which isn't necessarily linear.  Therefore, if we check the
modifier before that point, we might get wrong answers.

So, I kept the check inside the i915 driver and removed the check from
amdgpu and vmwgfx [4]. But, this yet hasn't solved the i915 problem [5].

As we cannot add the check inside framebuffer_check() without
affecting the i915 behavior, this commit went back to the original
patch. This way we can guarantee a more uniform behavior from the
drivers that use the drm_gem_fb_create() callback.

The amdgpu_dm_plane.h functions didn't have names that indicated where

To better filter results in debug tools like ftrace, prefix these

Note that we may want to make this same change in other files like
amdgpu_dm_crtc.h.

941aae3263 drm/todo: update the debugfs clean up task
The structs drm_debugfs_info and drm_debugfs_entry introduced a new
debugfs structure to DRM, centered on drm_device instead of drm_minor.
Therefore, remove the tasks related to create a new device-centered
debugfs structure and add a new task to replace the use of
drm_debugfs_create_files() for the use of drm_debugfs_add_file() and
drm_debugfs_add_files().

7d63cd8526
drm/connector: Add TV standard property
The TV mode property has been around for a while now to select and get the
current TV mode output on an analog TV connector.

Despite that property name being generic, its content isn't and has been
driver-specific which makes it hard to build any generic behaviour on top
of it, both in kernel and user-space.

Let's create a new enum tv norm property, that can contain any of the
analog TV standards currently supported by kernel drivers. Each driver can
then pass in a bitmask of the modes it supports, and the property
creation function will filter out the modes not supported.

We'll then be able to phase out the older tv mode property.

ee71434eeb drm/i915/mtl: Handle wopcm per-GT and limit calculations.
With MTL standalone media architecture the wopcm layout has changed,
with separate partitioning in WOPCM for the root GT GuC and the media
GT GuC. The size of WOPCM is 4MB with the lower 2MB reserved for the
media GT and the upper 2MB for the root GT.

Given that MTL has GuC deprivilege, the WOPCM registers are pre-locked
by the bios. Therefore, we can skip all the math for the partitioning
and just limit ourselves to sanity-checking the values.

v2: fix makefile file ordering (Jani)
v3: drop XELPM_SAMEDIA_WOPCM_SIZE, check huc instead of VDBOX (John)

bc0d7fdefe drm: vkms: Supports to the case where primary plane doesn't match the CRTC
We will remove the current assumption that the primary plane has the
same size and position as CRTC and that the primary plane is the
bottom-most in zpos order, or is even enabled. At least as far
as the blending machinery is concerned.

For that we will add CRTC dimension information to `vkms_crtc_state`
and add a opaque black backgound color.

Because now we need to fill the background, we had a loss in
performance with this change. Results running the IGT[1] test

8ba1648567 drm: vkms: Refactor the plane composer to accept new formats
Currently the blend function only accepts XRGB_8888 and ARGB_8888
as a color input.

This patch refactors all the functions related to the plane composition
to overcome this limitation.

The pixels blend is done using the new internal format. And new handlers
are being added to convert a specific format to/from this internal format.

So the blend operation depends on these handlers to convert to this common
format. The blended result, if necessary, is converted to the writeback
buffer format.

This patch introduces three major differences to the blend function.
1 - All the planes are blended at once.
2 - The blend calculus is done as per line instead of per pixel.
3 - It is responsible to calculates the CRC and writing the writeback
buffer(if necessary).

These changes allow us to allocate way less memory in the intermediate
buffer to compute these operations. Because now we don't need to
have the entire intermediate image lines at once, just one line is
enough.

|       Current      |     This patch    |
|:------------------:|:-----------------:|
|   Width * Heigth   |     2 * Width     |

these changes. Results running the IGT[1] test

4a83c26a1d drm/gem: rename GEM CMA helpers to GEM DMA helpers
Rename "GEM CMA" helpers to "GEM DMA" helpers - considering the
hierarchy of APIs (mm/cma -> dma -> gem dma) calling them "GEM
DMA" seems to be more applicable.

Besides that, commit e57924d4ae ("drm/doc: Task to rename CMA helpers")
requests to rename the CMA helpers and implies that people seem to be
confused about the naming.

In order to do this renaming the following script was used:

```
	#!/bin/bash

	DIRS="drivers/gpu include/drm Documentation/gpu"

	REGEX_SYM_UPPER="[0-9A-Z_\-]"
	REGEX_SYM_LOWER="[0-9a-z_\-]"

	REGEX_GREP_UPPER="(${REGEX_SYM_UPPER}*)(GEM)_CMA_(${REGEX_SYM_UPPER}*)"
	REGEX_GREP_LOWER="(${REGEX_SYM_LOWER}*)(gem)_cma_(${REGEX_SYM_LOWER}*)"

	REGEX_SED_UPPER="s/${REGEX_GREP_UPPER}/\1\2_DMA_\3/g"
	REGEX_SED_LOWER="s/${REGEX_GREP_LOWER}/\1\2_dma_\3/g"

	# Find all upper case 'CMA' symbols and replace them with 'DMA'.
	for ff in $(grep -REHl "${REGEX_GREP_UPPER}" $DIRS)
	do
	       sed -i -E "$REGEX_SED_UPPER" $ff
	done

	# Find all lower case 'cma' symbols and replace them with 'dma'.
	for ff in $(grep -REHl "${REGEX_GREP_LOWER}" $DIRS)
	do
	       sed -i -E "$REGEX_SED_LOWER" $ff
	done

	# Replace all occurrences of 'CMA' / 'cma' in comments and
	# documentation files with 'DMA' / 'dma'.
	for ff in $(grep -RiHl " cma " $DIRS)
	do
		sed -i -E "s/ cma / dma /g" $ff
		sed -i -E "s/ CMA / DMA /g" $ff
	done

	# Rename all 'cma_obj's to 'dma_obj'.
	for ff in $(grep -RiHl "cma_obj" $DIRS)
	do
		sed -i -E "s/cma_obj/dma_obj/g" $ff
	done
```

Only a few more manual modifications were needed, e.g. reverting the
following modifications in some DRM Kconfig files

    -       select CMA if HAVE_DMA_CONTIGUOUS
    +       select DMA if HAVE_DMA_CONTIGUOUS

as well as manually picking the occurrences of 'CMA'/'cma' in comments and
documentation which relate to "GEM CMA", but not "FB CMA".

Also drivers/gpu/drm/Makefile was fixed up manually after renaming
drm_gem_cma_helper.c to drm_gem_dma_helper.c.

This patch is compile-time tested building a x86_64 kernel with
`make allyesconfig && make drivers/gpu/drm`.

3fe6c7f53e drm/i915/gt: Cleanup interface for MCR operations
Let's replace the assortment of intel_gt_* and intel_uncore_* functions
that operate on MCR registers with a cleaner set of interfaces:

  * intel_gt_mcr_read -- unicast read from specific instance
  * intel_gt_mcr_read_any[_fw] -- unicast read from any non-terminated
    instance
  * intel_gt_mcr_unicast_write -- unicast write to specific instance
  * intel_gt_mcr_multicast_write[_fw] -- multicast write to all instances

We'll also replace the historic "slice" and "subslice" terminology with
"group" and "instance" to match the documentation for more recent
platforms; these days MCR steering applies to more types of replication
than just slice/subslice.

v2:
 - Reference the new kerneldoc from i915.rst.  (Jani)
 - Tweak the wording of the documentation for a couple functions to
   clarify the difference between "_fw" and non-"_fw" forms.

v3:
 - s/read/write/ to fix copy-paste mistake in a couple comments.

16490922a9 drm: vkms: Alloc the compose frame using vzalloc
Currently, the memory to the composition frame is being allocated using
the kzmalloc. This comes with the limitation of maximum size of one
page size(which in the x86_64 is 4Kb and 4MB for default and hugepage
respectively).

Somes test of igt (e.g. kms_plane@pixel-format) uses more than 4MB when
testing some pixel formats like ARGB16161616 and the following error were
showing up when running kms_plane@plane-panning-bottom-right*:

[drm:vkms_composer_worker [vkms]] *ERROR* Cannot allocate memory for
output frame.

This problem is addessed by allocating the memory using kvzalloc that
circunvents this limitation.

V5: Improve the commit message and drop the debugging issues in VKMS

Learning about the DRM subsystem could be quite overwhelming for newcomers
but there are lots of useful talks, slides and articles available that can
help to understand the needed concepts and ease the learning curve.

There are also simple DRM drivers that can be used as example about how a
DRM driver should look like.

Add sections to the introduction page, that contains references to these.

055634e4b6 drm/i915: Expose client engine utilisation via fdinfo
Similar to AMD commit
8744425411 ("drm/amdgpu: Add show_fdinfo() interface"), using the
infrastructure added in previous patches, we add basic client info
and GPU engine utilisation for i915.

Example of the output:

  pos:    0
  flags:  0100002
  mnt_id: 21
  drm-driver: i915
  drm-pdev:   0000:00:02.0
  drm-client-id:      7
  drm-engine-render:  9288864723 ns
  drm-engine-copy:    2035071108 ns
  drm-engine-video:   0 ns
  drm-engine-video-enhance:   0 ns

v2:
 * Update for removal of name and pid.

v3:
 * Use drm_driver.name.

v4:
 * Added drm-engine-capacity- tag.
 * Fix typo. (Umesh)

v5:
 * Don't output engine data before Gen8.

2d12d3da53 drm: Document fdinfo format specification
Proposal to standardise the fdinfo text format as optionally output by DRM
drivers.

Idea is that a simple but, well defined, spec will enable generic
userspace tools to be written while at the same time avoiding a more heavy
handed approach of adding a mid-layer to DRM.

i915 implements a subset of the spec, everything apart from the memory
stats currently, and a matching intel_gpu_top tool exists.

Open is to see if AMD can migrate to using the proposed GPU utilisation
key-value pairs, or if they are not workable to see whether to go
vendor specific, or if a standardised  alternative can be found which is
workable for both drivers.

Same for the memory utilisation key-value pairs proposal.

v2:
 * Update for removal of name and pid.

v3:
 * 'Drm-driver' tag will be obtained from struct drm_driver.name. (Daniel)

v4:
 * Added drm-engine-capacity- tag.

aa457ff1b2 drm/doc: Clarify what ioctls can be used on render nodes
The documentation for render nodes indicates that only "PRIME-related"
ioctls are valid on render nodes, but the documentation does not clarify
what that means.  If the reader is not familiar with PRIME, they may
beleive this to be only the ioctls with "PRIME" in the name and not other
ioctls such as set of syncobj ioctls.  Clarify the situation for the
reader by referencing where the reader will find a current list of valid
ioctls.

1d38fe6ee6 PCI/VGA: Move vgaarb to drivers/pci
The VGA arbiter is really PCI-specific and doesn't depend on any GPU
things.  Move it to the PCI subsystem.

Note that misc_init() must be called before vga_arb_device_init().  These
are both subsys_initcalls, so this ordering depends on the link order,
which is determined by drivers/Makefile:

  obj-y += pci/
  obj-y += char/        <-- misc_init()
  obj-y += gpu/         <-- vga_arb_device_init() (before this commit)

The drivers/pci/ subsys_initcalls are called *before* misc_init(), so
convert vga_arb_device_init() to subsys_initcall_sync(), which is called
after *all* subsys_initcalls.

7938f42181 dma-buf-map: Rename to iosys-map
Rename struct dma_buf_map to struct iosys_map and corresponding APIs.
Over time dma-buf-map grew up to more functionality than the one used by
dma-buf: in fact it's just a shim layer to abstract system memory, that
can be accessed via regular load and store, from IO memory that needs to
be acessed via arch helpers.

The idea is to extend this API so it can fulfill other needs, internal
to a single driver. Example: in the i915 driver it's desired to share
the implementation for integrated graphics, which uses mostly system
memory, with discrete graphics, which may need to access IO memory.

The conversion was mostly done with the following semantic patch:

	@r1@
	@@
	- struct dma_buf_map
	+ struct iosys_map

	@r2@
	@@
	(
	- DMA_BUF_MAP_INIT_VADDR
	+ IOSYS_MAP_INIT_VADDR
	|
	- dma_buf_map_set_vaddr
	+ iosys_map_set_vaddr
	|
	- dma_buf_map_set_vaddr_iomem
	+ iosys_map_set_vaddr_iomem
	|
	- dma_buf_map_is_equal
	+ iosys_map_is_equal
	|
	- dma_buf_map_is_null
	+ iosys_map_is_null
	|
	- dma_buf_map_is_set
	+ iosys_map_is_set
	|
	- dma_buf_map_clear
	+ iosys_map_clear
	|
	- dma_buf_map_memcpy_to
	+ iosys_map_memcpy_to
	|
	- dma_buf_map_incr
	+ iosys_map_incr
	)

	@@
	@@
	- #include <linux/dma-buf-map.h>
	+ #include <linux/iosys-map.h>

Then some files had their includes adjusted and some comments were
update to remove mentions to dma-buf-map.

Since this is not specific to dma-buf anymore, move the documentation to
the "Bus-Independent Device Accesses" section.

v2:
  - Squash patches

v3:
  - Fix wrong removal of dma-buf.h from MAINTAINERS
  - Move documentation from dma-buf.rst to device-io.rst

v4:
  - Change documentation title and level

87ab9f6b74 Revert "fbcon: Disable accelerated scrolling"
This reverts commit 39aead8373.

Revert the first (of 2) commits which disabled scrolling acceleration in
fbcon/fbdev.  It introduced a regression for fbdev-supported graphic cards
because of the performance penalty by doing screen scrolling by software
instead of using the existing graphic card 2D hardware acceleration.

Console scrolling acceleration was disabled by dropping code which
checked at runtime the driver hardware capabilities for the
BINFO_HWACCEL_COPYAREA or FBINFO_HWACCEL_FILLRECT flags and if set, it
enabled scrollmode SCROLL_MOVE which uses hardware acceleration to move
screen contents.  After dropping those checks scrollmode was hard-wired
to SCROLL_REDRAW instead, which forces all graphic cards to redraw every
character at the new screen position when scrolling.

This change effectively disabled all hardware-based scrolling acceleration for
ALL drivers, because now all kind of 2D hardware acceleration (bitblt,
fillrect) in the drivers isn't used any longer.

The original commit message mentions that only 3 DRM drivers (nouveau, omapdrm
and gma500) used hardware acceleration in the past and thus code for checking
and using scrolling acceleration is obsolete.

This statement is NOT TRUE, because beside the DRM drivers there are around 35
other fbdev drivers which depend on fbdev/fbcon and still provide hardware
acceleration for fbdev/fbcon.

The original commit message also states that syzbot found lots of bugs in fbcon
and thus it's "often the solution to just delete code and remove features".
This is true, and the bugs - which actually affected all users of fbcon,
including DRM - were fixed, or code was dropped like e.g. the support for
software scrollback in vgacon (commit 973c096f6a).

So to further analyze which bugs were found by syzbot, I've looked through all
patches in drivers/video which were tagged with syzbot or syzkaller back to
year 2005. The vast majority fixed the reported issues on a higher level, e.g.
when screen is to be resized, or when font size is to be changed. The few ones
which touched driver code fixed a real driver bug, e.g. by adding a check.

But NONE of those patches touched code of either the SCROLL_MOVE or the
SCROLL_REDRAW case.

That means, there was no real reason why SCROLL_MOVE had to be ripped-out and
just SCROLL_REDRAW had to be used instead. The only reason I can imagine so far
was that SCROLL_MOVE wasn't used by DRM and as such it was assumed that it
could go away. That argument completely missed the fact that SCROLL_MOVE is
still heavily used by fbdev (non-DRM) drivers.

Some people mention that using memcpy() instead of the hardware acceleration is
pretty much the same speed. But that's not true, at least not for older graphic
cards and machines where we see speed decreases by factor 10 and more and thus
this change leads to console responsiveness way worse than before.

That's why the original commit is to be reverted. By reverting we
reintroduce hardware-based scrolling acceleration and fix the
performance regression for fbdev drivers.

There isn't any impact on DRM when reverting those patches.

77b6f79df6 drm/i915/guc: Update to GuC version 69.0.3
Update to the latest GuC release.

The latest GuC firmware introduces a number of interface changes:

GuC may return NO_RESPONSE_RETRY message for requests sent over CTB.
Add support for this reply and try resending the request again as a
new CTB message.

A KLV (key-length-value) mechanism is now used for passing
configuration data such as CTB management.

With the new KLV scheme, the old CTB management actions are no longer
used and are removed.

Register capture on hang is now supported by GuC. Full i915 support
for this will be added by a later patch. A minimum support of
providing capture memory and register lists is required though, so add
that in.

The device id of the current platform needs to be provided at init time.

The 'poll CS' w/a (Wa_22012773006) was blanket enabled by previous
versions of GuC. It must now be explicitly requested by the KMD. So,
add in the code to turn it on when relevant.

The GuC log entry format has changed. This requires adding a new field
to the log header structure to mark the wrap point at the end of the
buffer (as the buffer size is no longer a multiple of the log entry
size).

New CTB notification messages are now sent for some things that were
previously only sent via MMIO notifications.

Of these, the crash dump notification was not really being handled by
i915. It called the log flush code but that only flushed the regular
debug log and then only if relay logging was enabled. So just report
an error message instead.

The 'exception' notification was just being ignored completely. So add
an error message for that as well.

Note that in either the crash dump or the exception case, the GuC is
basically dead. The KMD will detect this via the heartbeat and trigger
both an error log (which will include the crash dump as part of the
GuC log) and a GT reset. So no other processing is really required.

a1a9868930 drm: Add privacy-screen class (v4)
On some new laptops the LCD panel has a builtin electronic privacy-screen.
We want to export this functionality as a property on the drm connector
object. But often this functionality is not exposed on the GPU but on some
other (ACPI) device.

This commit adds a privacy-screen class allowing the driver for these
other devices to register themselves as a privacy-screen provider; and
allowing the drm/kms code to get a privacy-screen provider associated
with a specific GPU/connector combo.

Changes in v2:
- Make CONFIG_DRM_PRIVACY_SCREEN a bool which controls if the drm_privacy
  code gets built as part of the main drm module rather then making it
  a tristate which builds its own module.
- Add a #if IS_ENABLED(CONFIG_DRM_PRIVACY_SCREEN) check to
  drm_privacy_screen_consumer.h and define stubs when the check fails.
  Together these 2 changes fix several dependency issues.
- Remove module related code now that this is part of the main drm.ko
- Use drm_class as class for the privacy-screen devices instead of
  adding a separate class for this

Changes in v3:
- Make the static inline drm_privacy_screen_get_state() stub set sw_state
  and hw_state to PRIVACY_SCREEN_DISABLED to squelch an uninitialized
  variable warning when CONFIG_DRM_PRIVICAY_SCREEN is not set

Changes in v4:
- Make drm_privacy_screen_set_sw_state() skip calling out to the hw if
  hw_state == new_sw_state

107fe90430 drm/connector: Add support for privacy-screen properties (v4)
Add support for generic electronic privacy screen properties, that
can be added by systems that have an integrated EPS.

Changes in v2 (Hans de Goede)
- Create 2 properties, "privacy-screen sw-state" and
  "privacy-screen hw-state", to deal with devices where the OS might be
  locked out of making state changes
- Write kerneldoc explaining how the 2 properties work together, what
  happens when changes to the state are made outside of the DRM code's
  control, etc.

Changes in v3 (Hans de Goede)
- Some small tweaks to the kerneldoc describing the 2 properties

Changes in v4 (Hans de Goede)
- Change the "Enabled, locked" and "Disabled, locked" hw-state enum value
  names to "Enabled-locked" and "Disabled-locked". The xrandr command shows
  all possible enum values separated by commas in its output, so having a
  comma in an enum name is not a good idea.
- Do not add a privacy_screen_hw_state member to drm_connector_state
  since this property is immutable its value must be directly stored in the
  obj->properties->values array

drm/bridge: Document the probe issue with MIPI-DSI bridges
Interactions between bridges, panels, MIPI-DSI host and the component
framework are not trivial and can lead to probing issues when
implementing a display driver. Let's document the various cases we need
too consider, and the solution to support all the cases.

Pull drm updates from Dave Airlie:
 "Highlights:

   - i915 has seen a lot of refactoring and uAPI cleanups due to a
     change in the upstream direction going forward

     This has all been audited with known userspace, but there may be
     some pitfalls that were missed.

   - i915 now uses common TTM to enable discrete memory on DG1/2 GPUs

   - i915 enables Jasper and Elkhart Lake by default and has preliminary
     XeHP/DG2 support

   - amdgpu adds support for Cyan Skillfish

   - lots of implicit fencing rules documented and fixed up in drivers

   - msm now uses the core scheduler

   - the irq midlayer has been removed for non-legacy drivers

   - the sysfb code now works on more than x86.

  Otherwise the usual smattering of stuff everywhere, panels, bridges,
  refactorings.

  Detailed summary:

3a3dd5342f drm/i915/display: Renaming DRRS functions to intel_drrs_*()
We had a mix of intel_edp_drrs_*(), intel_dp_drrs_*() and
intel_dp_set_drrs_state(), so properly renaming all functions to
keep the same pattern.

While at it, also dropping intel_dp_set_drrs_state from the
documentation as it is a static function.

v3:
- dropping documentation style comment in static function
(intel_drrs_set_state)

981b04d968 drm/sched: improve docs around drm_sched_entity
I found a few too many things that are tricky and not documented, so I
started typing.

I found a few more things that looked broken while typing, see the
varios FIXME in drm_sched_entity.

Also some of the usual logics:
- actually include sched_entity.c declarations, that was lost in the
  move here: 620e762f9a ("drm/scheduler: move entity handling into
  separate file")

- Ditch the kerneldoc for internal functions, keep the comments where
  they're describing more than what the function name already implies.

- Switch drm_sched_entity to inline docs.

ffd5caa26f drm/doc/rfc: drop lmem uapi section
We still have quite a bit more work to do with overall reworking of
the ttm-based dg1 code, but the uapi stuff is now finalized with the
latest pull. So remove that.

This also fixes kerneldoc build warnings because we've included the
same headers in two places, resulting in sphinx complaining about
duplicated symbols. This regression has been created when we moved the
uapi definitions to the real include/uapi/ folder in 727ecd99a4
("drm/doc/rfc: drop the i915_gem_lmem.h header")

v2: Fix a few references that I missed, the htmldocs build took

25fed6b324 Merge tag 'drm-intel-gt-next-2021-08-06-1' of ssh://git.freedesktop.org/git/drm/drm-intel into drm-next
UAPI Changes:

- Add I915_MMAP_OFFSET_FIXED

  On devices with local memory `I915_MMAP_OFFSET_FIXED` is the only valid
  type. On devices without local memory, this caching mode is invalid.

  As caching mode when specifying `I915_MMAP_OFFSET_FIXED`, WC or WB will
  be used, depending on the object placement on creation. WB will be used
  when the object can only exist in system memory, WC otherwise.

  Userspace: https://gitlab.freedesktop.org/mesa/mesa/-/merge_requests/11888

- Reinstate the mmap ioctl for (already released) integrated Gen12 platforms

  Rationale: Otherwise media driver breaks eg. for ADL-P. Long term goal is
  still to sunset the IOCTL even for integrated and require using mmap_offset.

- Reject caching/set_domain IOCTLs on discrete

  Expected to become immutable property of the BO

- Disallow changing context parameters after first use on Gen12 and earlier
- Require setting context parameters at creation on platforms after Gen12

  Rationale (for both): Allow less dynamic changes to the context to simplify
  the implementation and avoid user shooting theirselves in the foot.

- Drop I915_CONTEXT_PARAM_RINGSIZE

  Userspace PR for compute-driver has not been merged

- Drop I915_CONTEXT_PARAM_NO_ZEROMAP

  Userspace PR for libdrm / Beignet was never landed

- Drop CONTEXT_CLONE API

  Userspace PR for Mesa was never landed

- Drop getparam support for I915_CONTEXT_PARAM_ENGINES

  Only existed for symmetry wrt. setparam, never used.

- Disallow bonding of virtual engines

  Drop the prep work, no hardware has been released needing it.

- (Implicit) Disable gpu relocations

  Media userspace was the last userspace to still use them. They
  have converted so performance can be regained with an update.

d793b8f732 drm: clarify usage of drm leases
We make the following changes to the documentation of drm leases to
make it easier to reason about their usage. In particular, we clarify
the lifetime and locking rules of lease fields in drm_master:

1. Make it clear that &drm_device.mode_config.idr_mutex protects the
lease idr and list structures for drm_master. The lessor field itself
doesn't need to be protected as it doesn't change after it's set in
drm_lease_create.

2. Add descriptions for the lifetime of lessors and leases.

3. Add an overview DOC: section in drm-uapi.rst that defines the
terminology for drm leasing, and explains how leases work and why
they're used.

1cbf731ef3 drm/i915: Fix missing docbook chapters for i915 uapi.
I noticed when grepping for DOC: that those were defined
in the header, but not actually used. Fix it by removing
all chapters and the internal annotation, so the docbook
generated chapters are used.

This reverts the changes to driver-uapi.rst by the referenced commit

3e28d37146 drm/i915: Move priolist to new i915_sched_engine object
Introduce i915_sched_engine object which is lower level data structure
that i915_scheduler / generic code can operate on without touching
execlist specific structures. This allows additional submission backends
to be added without breaking the layering. Currently the execlists
backend uses 1 of these object per each engine (physical or virtual) but
future backends like the GuC will point to less instances utilizing the
reference counting.

This is a bit of detour to integrating the i915 with the DRM scheduler
but this object will still exist when the DRM scheduler lands in the
i915. It will however look a bit different. It will encapsulate the
drm_gpu_scheduler object plus and common variables (to the backends)
related to scheduling. Regardless this is a step in the right direction.

This patch starts the aforementioned transition by moving the priolist
into the i915_sched_engine object.

Nevertheless, we did not document it in detail in our driver. This
commit introduces a kernel-doc and expands the module parameter
description.

b7e32bef4a drm: Add a prefetching memcpy_from_wc
Reading out of write-combining mapped memory is typically very slow
since the CPU doesn't prefetch. However some archs have special
instructions to do this.

So add a best-effort memcpy_from_wc taking dma-buf-map pointer
arguments that attempts to use a fast prefetching memcpy and
otherwise falls back to ordinary memcopies, taking the iomem tagging
into account.

The code is largely copied from i915_memcpy_from_wc.

727ecd99a4 drm/doc/rfc: drop the i915_gem_lmem.h header

can drop i915_gem_lmem.h and instead just reference the real headers for
