Merge v6.8-rc6 into drm-next

Thomas Zimmermann asked to backmerge -rc6 for drm-misc branches,
there's a few same-area-changed conflicts (xe and amdgpu mostly) that
are getting a bit too annoying.

Maarten Lankhorst 76a86b58d2 drm/xe: Add uapi for dumpable bos
Add the flag XE_VM_BIND_FLAG_DUMPABLE to notify devcoredump that this
mapping should be dumped.

This is not hooked up, but the uapi should be ready before merging.

It's likely easier to dump the contents of the bo's at devcoredump
readout time, so it's better if the bos will stay unmodified after
a hang. The NEEDS_CPU_MAPPING flag is removed as requirement.

Thomas Hellström 77aebae1ea drm/xe/uapi: Remove support for persistent exec_queues
Persistent exec_queues delays explicit destruction of exec_queues
until they are done executing, but destruction on process exit
is still immediate. It turns out no UMD is relying on this
functionality, so remove it. If there turns out to be a use-case
in the future, let's re-add.

Persistent exec_queues were never used for LR VMs

v2:
- Don't add an "UNUSED" define for the missing property
  (Lucas, Rodrigo)
v3:
- Remove the remaining struct xe_exec_queue::persistent state

Tvrtko Ursulin b112364867 drm/i915: Add GuC submission interface version query
Add a new query to the GuC submission interface version.

Mesa intends to use this information to check for old firmware versions
with a known bug where using the render and compute command streamers
simultaneously can cause GPU hangs due issues in firmware scheduling.

Based on patches from Vivaik and Joonas.

Compile tested only.

v2:
 * Added branch version.

José Roberto de Souza 9bc36e58d1 drm/xe: Add uAPI to query GuC firmware submission version
Due to a bug in GuC firmware, Mesa can't enable by default the usage of
compute engines in DG2 and newer.

A new GuC firmware fixed the issue but until now there was no way
for Mesa to know if KMD was running with the fixed GuC version or not,
so this uAPI is required.

It may be expanded in future to query other firmware versions too.

This is querying XE_UC_FW_VER_COMPATIBILITY/submission version because
that is also supported by VFs, while XE_UC_FW_VER_RELEASE don't.

i915 uAPI: https://patchwork.freedesktop.org/series/129627/
Mesa usage: https://gitlab.freedesktop.org/mesa/mesa/-/merge_requests/25233

v2:
- fixed drm_xe_query_uc_fw_version documentation
- moved branch_ver as the first version number

As of commit b77fdd6a48 ("scripts/kernel-doc: restore warning for
Excess struct/union"), we see the following warnings when running 'make
htmldocs':

  ./include/uapi/drm/nouveau_drm.h:292: warning: Excess struct member 'DRM_NOUVEAU_VM_BIND_OP_MAP' description in 'drm_nouveau_vm_bind_op'
  ./include/uapi/drm/nouveau_drm.h:292: warning: Excess struct member 'DRM_NOUVEAU_VM_BIND_OP_UNMAP' description in 'drm_nouveau_vm_bind_op'
  ./include/uapi/drm/nouveau_drm.h:292: warning: Excess struct member 'DRM_NOUVEAU_VM_BIND_SPARSE' description in 'drm_nouveau_vm_bind_op'
  ./include/uapi/drm/nouveau_drm.h:336: warning: Excess struct member 'DRM_NOUVEAU_VM_BIND_RUN_ASYNC' description in 'drm_nouveau_vm_bind'

The problem is that these values are #define constants, but had kerneldoc
comments attached to them as if they were actual struct members.

There are a number of ways we could fix this, but I chose to draw
inspiration from include/uapi/drm/i915_drm.h, which pulls them into the
corresponding kerneldoc comment for the struct member that they are
intended to be used with.

To keep the diff readable, there are a number of things I _didn't_ do in
this patch, but which we should also consider:

- This is pretty good documentation, but it ends up in gpu/driver-uapi,
  which is part of subsystem-apis/ when it really ought to display under
  userspace-api/ (the "Linux kernel user-space API guide" book of the
  documentation).

- More generally, we might want a warning if include/uapi/ files are
  kerneldoc'd outside userspace-api/.

- I'd consider it cleaner if the #defines appeared between the kerneldoc
  for the member and the member itself (which is something other DRM-
  related UAPI docs do).

- The %IDENTIFIER kerneldoc syntax is intended for "constants", and is
  more appropriate in this context than ``IDENTIFIER`` or &IDENTIFIER.
  The DRM docs aren't very consistent on this.

Francois Dugast 33c6fda687 drm/xe/uapi: Add block diagram of a device
In order to make proper use the uAPI, a prerequisite is to understand
some key concepts about the discrete GPU devices which are supported
by the Xe driver. For example, some structs defined in the uAPI are an
abstraction of a hardware component with a specific role.

This diagram helps to build a mental representation of a device how it
is seen by the Xe driver. As written in the documentation, it does not
intend to be a literal representation of an existing device. A lot
more information could be added but the intention for the overview is
to keep it simple, and go into detail as needed in other sections.

The uAPI should stay generic in regarding to the bitmask. It is
the userspace responsibility to check for the type/class of the
memory, without any assumption.

Also add comments inside the code to explain how it is actually
constructed so we don't accidentally change the assignment of
the instance and the masks.

No functional change in this patch. It only explains and document
the memory_region masks. A further follow-up work with the
organization of all memory regions around struct xe_mem_regions
is desired, but not part of this patch.

Rodrigo Vivi 76ca3a22c0 drm/xe/uapi: Order sections
This patch doesn't modify any text or uapi entries themselves.
It only move things up and down aiming a better organization of the uAPI.

While fixing the documentation I noticed that query_engine_cs_cycles
was in the middle of the memory_region info. Then I noticed more
mismatches on the order when compared to the order of the IOCTL
and QUERY entries declaration. So this patch aims to bring some
order to the uAPI so it gets easier to read and the documentation
generated in the end is able to tell a consistent story.

Overall order:

1. IOCTL definition
2. Extension definition and helper structs
3. IOCTL's Query structs in the order of the Query's entries.
4. The rest of IOCTL structs in the order of IOCTL declaration.
5. uEvents

using the existent extension. So, let's kill this useless and dangerous
uapi.

Rodrigo Vivi 9209fbede7 drm/xe: Remove unused extension definition
The vm_create ioctl function doesn't accept any extension.
Remove this left over.

Thomas Hellström 9329f06672 drm/xe/uapi: Use LR abbrev for long-running vms
Currently we're using "compute mode" for long running VMs using
preempt-fences for memory management, and "fault mode" for long
running VMs using page faults.

Change this to use the terminology "long-running" abbreviated as LR for
long-running VMs. These VMs can then either be in preempt-fence mode or
fault mode. The user can force fault mode at creation time, but otherwise
the driver can choose to use fault- or preempt-fence mode for long-running
vms depending on the device capabilities. Initially unless fault-mode is
specified, the driver uses preempt-fence mode.

v2:
- Fix commit message wording and the documentation around
  CREATE_FLAG_LR_MODE and CREATE_FLAG_FAULT_MODE

Rodrigo Vivi 926ad2c380 drm/xe/uapi: Move xe_exec after xe_exec_queue
Although the exec ioctl is a very important one, it makes no sense
to explain xe_exec before explaining the exec_queue. So, let's
move this down to help bring a better flow on the documentation
and code readability.

It is important to highlight that this patch is changing all
the ioctl numbers in a non-backward compatible way. However, we
are doing this final uapi clean-up before we submit our first
pull-request to be part of the upstream Kernel. Once we get
there, no other change like this will ever happen and all the
backward compatibility will be respected.

Rodrigo Vivi 7a56bd0cfb drm/xe/uapi: Fix various struct padding for 64b alignment
Let's respect Documentation/process/botching-up-ioctls.rst
and add the proper padding for a 64b alignment with all as
well as all the required checks and settings for the pads
and the reserved entries.

v2: Fix remaining holes and double check with pahole (Jose)
    Ensure with pahole that both 32b and 64b have exact same
    layout (Thomas)
    Do not set query's pad and reserved bits to zero since it
    is redundant and already done by kzalloc (Matt)

v3: Fix alignment after rebase (José Roberto de Souza)

v4: Fix pad check (Francois Dugast)
