When generating the default LRC, if a register is not masked, we apply
any save-restore programming necessary via a read-modify-write sequence
that will ensure we only update the relevant bits/fields without
clobbering the rest of the register. However some of the registers that
need to be updated might be MCR registers which require steering to a
non-terminated instance to ensure we can read back a valid, non-zero
value. The steering of reads originating from a command streamer is
controlled by register CS_MMIO_GROUP_INSTANCE_SELECT. Emit additional
MI_LRI commands to update the steering before any RMW of an MCR register
to ensure the reads are performed properly.
Note that needing to perform a RMW of an MCR register while building the
default LRC is pretty rare. Most of the MCR registers that are part of
an engine's LRCs are also masked registers, so no MCR is necessary.

clangd reports many "unused header" warnings throughout the Xe driver.
Start working to clean this up by removing unnecessary includes in our
.c files and/or replacing them with explicit includes of other headers
that were previously being included indirectly.
By far the most common offender here was unnecessary inclusion of
xe_gt.h. That likely originates from the early days of xe.ko when
xe_mmio did not exist and all register accesses, including those
unrelated to GTs, were done with GT functions.
There's still a lot of additional #include cleanup that can be done in
the headers themselves; that will come as a followup series.

Previously, compressible surfaces were required to be non-coherent
(allocated as WC) because compression and coherency were mutually
exclusive. Starting with Xe3, hardware supports combining compression
with 1-way coherency, allowing compressible surfaces to be allocated as
WB memory. This provides applications with more efficient memory
allocation by avoiding WC allocation overhead that can cause system
stuttering and memory management challenges.
The implementation adds support for compressed+coherent PAT entry for
the xe3_lpg devices and updates the driver logic to handle the new
compression capabilities.

During GT reset recovery in do_gt_restart(), xe_uc_start() was called
before xe_reg_sr_apply_mmio() restored engine-specific registers. This
created a race window where the scheduler could run jobs before hardware
state was fully restored.
This caused failures in eudebug tests (xe_exec_sip_eudebug@breakpoint-
waitsip-*) where TD_CTL register (containing TD_CTL_GLOBAL_DEBUG_ENABLE)
wasn't restored before jobs started executing. Breakpoints would fail to
trigger SIP entry because the debug enable bit wasn't set yet.
Fix by moving xe_uc_start() after all MMIO register restoration,
including engine registers and CCS mode configuration, ensuring all
hardware state is fully restored before any jobs can be scheduled.

While the late PF per-GT initialization is done quite late in the
single GT initialization flow, in case of multi-GT platforms, it

All recent platforms (including all the ones officially supported by the
Xe driver) do not allow concurrent execution of RCS and CCS workloads
from different address spaces, with the HW blocking the context switch
when it detects such a scenario.
The DUAL_QUEUE flag helps with this, by causing the GuC to not submit a
context it knows will not be able to execute. This, however, causes a new
problem: if RCS and CCS queues have pending workloads from different
address spaces, the GuC needs to choose from which of the 2 queues to
pick the next workload to execute. By default, the GuC prioritizes RCS
submissions over CCS ones, which can lead to CCS workloads being
significantly (or completely) starved of execution time.
The driver can tune this by setting a dedicated scheduling policy KLV;
this KLV allows the driver to specify a quantum (in ms) and a ratio
(percentage value between 0 and 100), and the GuC will prioritize the CCS
for that percentage of each quantum.
Given that we want to guarantee enough RCS throughput to avoid missing
frames, we set the yield policy to 20% of each 80ms interval.
v2: updated quantum and ratio, improved comment, use xe_guc_submit_disable
in gt_sanitize

Resetting GuC during recovery could interfere with the recovery
process. Such reset might be also triggered without justification,
due to migration taking time, rather than due to the workload not
progressing.
Doing GuC reset during the recovery would cause exit of RESFIX state,
and therefore continuation of GuC work while fixups are still being
applied. To avoid that, reset needs to be blocked during the recovery.
This patch blocks the reset during recovery. Reset request in that
time range will be stalled, and unblocked only after GuC goes out
of RESFIX state.
In case a reset procedure already started while the recovery is
triggered, there isn't much we can do - we cannot wait for it to
finish as it involves waiting for hardware, and we can't be sure
at which exact point of the reset procedure the GPU got switched.
Therefore, the rare cases where migration happens while reset is
in progress, are still dangerous. Resets are not a part of the
standard flow, and cause unfinished workloads - that will happen
during the reset interrupted by migration as well, so it doesn't
diverge that much from what normally happens during such resets.
v2: Introduce a new atomic for reset blocking, as we cannot reuse
`stopped` atomic (that could lead to losing a workload).

The bb allocation in emit_wa_job() is wrong in 2 ways: first it's
allocating enough space for the 3DSTATE or hardcoding 4k depending on
the engine. In the first case it doesn't account for the WAs and in the
former it may not be sufficient. Secondly it's using the size instead of
number of dwords, causing the buffer to be 4x bigger than needed:
xe_bb_new() receives number of dwords as parameter and its declaration
was also not following its implementation.
Lastly, reword the debug message since it's not only about the LRC WAs
anymore as it also include the 3DSTATE for render.

The workqueue used for the reset worker is marked as WQ_MEM_RECLAIM,
while the GSC one isn't (and can't be as we need to do memory
allocations in the gsc worker). Therefore, we can't flush the latter
from the former.
The reason why we had such a flush was to avoid interrupting either
the GSC FW load or in progress GSC proxy operations. GSC proxy
operations fall into 2 categories:
1) GSC proxy init: this only happens once immediately after GSC FW load
and does not support being interrupted. The only way to recover from
an interruption of the proxy init is to do an FLR and re-load the GSC.
2) GSC proxy request: this can happen in response to a request that
the driver sends to the GSC. If this is interrupted, the GSC FW will
timeout and the driver request will be failed, but overall the GSC
will keep working fine.
Flushing the work allowed us to avoid interruption in both cases (unless
the hang came from the GSC engine itself, in which case we're toast
anyway). However, a failure on a proxy request is tolerable if we're in
a scenario where we're triggering a GT reset (i.e., something is already
gone pretty wrong), so what we really need to avoid is interrupting
the init flow, which we can do by polling on the register that reports
when the proxy init is complete (as that ensure us that all the load and
init operations have been completed).
Note that during suspend we still want to do a flush of the worker to
make sure it completes any operations involving the HW before the power
is cut.
