812ec747a3 drm/xe: Sync MTL PCI IDs with i915
For Xe1 platforms, it's better to follow the way i915 adds the PCI IDs
to the header, so it's easier to catch up when there is an update. This
brings the same logic applied in commit 2e3c369f23 ("drm/i915/mtl:
Eliminate subplatforms") to the equivalent xe header.

The end result of this header for Xe1 platforms is now in sync with i915
as of commit 5032c607e8 ("drm/i915: ATS-M device ID update"). This can
be seen by

	$ git show 5032c607e886:include/drm/i915_pciids.h > a.h
	$ git diff --color-words  --no-index a.h include/drm/xe_pciids.h

fdb6a05383 drm/xe: Internally change the compute_mode and no_dma_fence mode naming
The name "compute_mode" can be confusing since compute uses either this
mode or fault_mode to achieve the long-running semantics, and compute_mode
can, moving forward, enable fault_mode under the hood to work around
hardware limitations.

Also the name no_dma_fence_mode really refers to what we elsewhere call
long-running mode and the mode contrary to what its name suggests allows
dma-fences as in-fences.

So in an attempt to be more consistent, rename
no_dma_fence_mode -> lr_mode
compute_mode      -> preempt_fence_mode

And adjust flags so that

preempt_fence_mode sets XE_VM_FLAG_LR_MODE
fault_mode sets XE_VM_FLAG_LR_MODE | XE_VM_FLAG_FAULT_MODE

- Fix a typo in the commit message (Oak Zeng)

d2f51c50b9 drm/xe/vm: Fix ASID XA usage
xa_alloc_cyclic() returns 1 on successful allocation, if wrapping occurs,
but the code incorrectly treats that as an error. Fix that.
Also, xa_alloc_cyclic() requires xa_init_flags(..., XA_FLAGS_ALLOC), so
fix that, and assuming we don't want a zero ASID, instead of using
XA_FLAGS_ALLOC1, adjust the xa limits at alloc_cyclic time.

v2:
- On CONFIG_DRM_XE_DEBUG, Initialize the cyclic ASID allocation in such a
  way that the next allocated ASID will be the maximum one, and the one
  following will cause an ASID wrap, (all to have CI test high ASIDs
  and ASID wraps).
v3:
- Stricter return value checking from xa_alloc_cyclic() (Matthew Auld)

We will be adding support for the SR-IOV and driver might be then
running, in addition to existing non-virtualized bare-metal mode,
also in Physical Function (PF) or Virtual Function (VF) mode.

Since these additional modes require some changes to the driver,
define enum flag to represent different SR-IOV modes and add a
function where we will detect the actual mode in the runtime.

We start with a forced bare-metal mode as it is sufficient to
enable basic functionality and ensures no impact to existing code.

b3f0654f55 drm/xe/mmio: Make xe_mmio_wait32() aware of interrupts
With the current implementation, a preemption or other kind of interrupt
might happen between xe_mmio_read32() and ktime_get_raw(). Such an
interruption (specially in the case of preemption) might be long enough
to cause a timeout without giving a chance of a new check on the
register value on a next iteration, which would have happened otherwise.

This issue causes some sporadic timeouts in some code paths. As an
example, we were experiencing some rare timeouts when waiting for PLL
unlock for C10/C20 PHYs (see intel_cx0pll_disable()). After debugging,
we found out that the PLL unlock was happening within the expected time
period (20us), which suggested a bug in xe_mmio_wait32().

To fix the issue, ensure that we do a last check out of the loop if
necessary.

This change was tested with the aforementioned PLL unlocking code path.
Experiments showed that, before this change, we observed reported
timeouts in 54 of 5000 runs; and, after this change, no timeouts were
reported in 5000 runs.

v2:
  - Prefer an implementation without a barrier (v1 switched the order of
    xe_mmio_read32() and ktime_get_raw() calls and added a barrier() in
    between). (Lucas, Rodrigo)

5c09bd6ccd drm/xe/mmio: Move xe_mmio_wait32() to xe_mmio.c
This function is big enough, let's move it to a shared compilation unit.

While at it, document it.

Here is the output of running bloat-o-metter on the new and old module
(execution provided by Lucas):

    $ ./scripts/bloat-o-meter build64/drivers/gpu/drm/xe/xe.ko{.old,}
    add/remove: 2/0 grow/shrink: 0/58 up/down: 554/-15645 (-15091)
    (...) # Lines in between omitted
    Total: Before=2181322, After=2166231, chg -0.69%

The overall reduction in the size is not that significant. Nevertheless,
keeping the function as inline arguably does not bring too much benefit
as well.

As noted by Lucas, we would probably benefit from an inline
function that did the fast-path check: do an optimistic first check
before entering the wait-logic, which itself would go to a compilation
unit. We might come back to implement this in the future if we have data
to justify it.

v2:
  - Add note in documentation for @timeout_us regarding the exponential
    backoff strategy. (Lucas)
  - Share output of bloat-o-meter in the commit message. (Lucas)

1d087cb7d8 drm/xe/guc: Fix handling of GUC_HXG_TYPE_NO_RESPONSE_BUSY
If GuC responds with the NO_RESPONSE_BUSY message, we extend
our timeout while waiting for the actual response, but we wrongly
assumed that the next message will be RESPONSE_SUCCESS, missing
that we still can get RESPONSE_FAILURE.

Change the condition for the expected message type, using only
common bits from RESPONSE_SUCCESS and RESPONSE_FAILURE (as they
differ, by ABI design, only by the last bit).

b02606d323 drm/xe/uapi: Rename query's mem_usage to mem_regions
'Usage' gives an impression of telemetry information where someone
would query to see how the memory is currently used and available
size, etc. However this API is more than this. It is about a global
view of all the memory regions available in the system and user
space needs to have this information so they can then use the
mem_region masks that are returned for the engine access.

45c30d8000 drm/xe/uapi: Rename *_mem_regions masks
- 'native' doesn't make much sense on integrated devices.
- 'slow' is not necessarily true and doesn't go well with opposition
  to 'native'.

Instead, let's use 'near' vs 'far'. It makes sense with all the current
Intel GPUs and it is future proof. Right now, there's absolutely no need
to define among the 'far' memory, which ones are slower, either in terms
of latency, nunmber of hops or bandwidth.

In case of this might become a requirement in the future, a new query
could be added to indicate the certain 'distance' between a given engine
and a memory_region. But for now, this fulfill all of the current
requirements in the most straightforward way for the userspace drivers.
