...
The caching mode for buffer objects with VRAM as a possible
placement was forced to write-combined, regardless of placement.
However, write-combined system memory is expensive to allocate and
even though it is pooled, the pool is expensive to shrink, since
it involves global CPU TLB flushes.
Moreover write-combined system memory from TTM is only reliably
available on x86 and DGFX doesn't have an x86 restriction.
So regardless of the cpu caching mode selected for a bo,
internally use write-back caching mode for system memory on DGFX.
Coherency is maintained, but user-space clients may perceive a
difference in cpu access speeds.

In Xe, the perf layer allows capture of HW counter streams. These HW
counters are generally performance related but don't have to be necessarily
so. Also, the name "perf" is a carryover from i915 and is not preferred.
Here we propose the name "observation" for this common layer which allows
capture of different types of these counter streams.

The OA stream open perf op returns an fd with its own file_operations for
the newly initialized OA stream. These file_operations allow userspace to
enable or disable the stream, as well as apply a different metric
configuration for the OA stream. Userspace can also poll for data

enabling the OA stream. When sampling is enabled this starts a hrtimer

In Xe, the plan is to support multiple types of perf counter streams (OA is
only one type of these streams). Rather than introduce NxM ioctls for
these (N perf streams with M ioctl's per perf stream), we decide to
multiplex these (N different stream types and the M ops for each of these
stream types) through a single PERF ioctl. This multiplexing is the purpose
of the PERF layer.
In addition to PERF DRM ioctl's, another set of ioctl's on the PERF fd are
defined. These are expected to be common to different PERF stream types and
therefore defined at the PERF layer itself.

The L3 bank mask is already generated and stored internally with
the rest of the GT topology. In user space, the compute runtime
now needs this information to be added to the device properties
therefore the topology mask query is extended to provide a new
mask which represents the L3 banks enabled on the GT.

The commit 84a1ed5e67 ("drm/xe/uapi: Remove unused flags") is partially
reverted. At the time, flags not used by user space were removed during
cleanup. Some flags now needed by the compute runtime are brought back in
this commit:
- DRM_XE_VM_BIND_FLAG_READONLY is used to write protect kernel ISA thus
preventing accidental overwrites.
- DRM_XE_VM_BIND_FLAG_IMMEDIATE is used to trigger mapping at the time of
binding in order to prevent faulting at execution time.

For modern platforms (MTL and later), both kernel and userspace drivers
are expected to apply GT programming and workarounds based on the IP
version and stepping self-reported by the GT hardware via the GMD_ID
registers. Since userspace drivers can't access these registers
directly, pass along the version and stepping information via the GT
list query. Note that the new query fields will remain 0's when running
on pre-GMD_ID platforms. Userspace is expected to continue using PCI
devid / revid on those older platforms.
Although the hardware also has a GMD_ID register for display
version/stepping, that value is intentionally *not* included anywhere in
the Xe uapi. Display userspace should be using platform-agnostic APIs
and auto-detecting platform capabilities rather than matching specific
IP versions.

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.

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.

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

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.

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)

As an information only. So Userspace can use this information
and be able to correlate different GTs.
Make API symmetric between Engine and GT info.
There's no need right now to include a tile_query entry
since there's no other information that we need from tile
that is not already exposed through different queries.
However, this could be added later if we have different Tile
information that could matter to userspace. But let's keep
the API ready for a direct reference to Tile ID based on
the GT entry.

First of all, let's remove the duplication.
But also, let's rename it to remove the word 'frequency'
out of it. In general, the first thing people think of frequency
is the frequency in which the GTs are operating to execute the
GPU instructions.
While this frequency here is a crystal reference clock frequency
which is the base of everything else, and in this case of this
uAPI it is used to calculate a better and precise timestamp.
v2: (Suggested by Jose) Remove the engine_cs and keep the GT info one
since it might be useful for other SRIOV cases where the engine_cs
will be zeroed. So, grabbing from the GT_LIST should be cleaner.
v3: Keep comment on put_user() call (José Roberto de Souza)
