Indirect context setup will need to get to the number of written dwords.
Lets add it as an output parameter so it can be accessed from the finish
helper regardless of whether code is writing directly or via an shadow
buffer.

Generalize the wa bb emission by splitting it into three phases - setup,
emit and finish, and extract setup and finish steps into helpers.
This will enable using the same infrastructure for emitting the indirect

Document xe module params with the default values following a similar
strategy for all of them:
1) Define a DEFAULT_* macro with the default value. When the
value can't be directly stringified, also define a *_STR
variant
2) Use __stringify() or the _STR variant to make sure the
default value shows up in the param description
This allows us to show the correct default according to the
configuration. max_vfs for example was wrongly documented for
CONFIG_DRM_XE_DEBUG and svm_notifier_size didn't have its default
documented.

The check would fail if the address is unaligned, but not when
accounting the offset. Instead of `buf | offset` it should have
been `buf + offset`. To make it more readable and also drop the

Currently xe sets the guc log level to a verbose level since it's useful
to debug hangs and general development. However the verbose level may
already be too much and affect performance.
Michal Mrozek did some tests with the L0 compute stack for submission
latency with ULLS disabled. Below are the normalized numbers with log
level 3 (the current default) as baseline for each test:
Test \ Log Level 3 0 1 2
----------------------------------------------------------- ------ ------ ------ ------
BestWalkerNthCommandListSubmission(CmdListCount=2) 1.00 0.63 0.63 0.96
BestWalkerNthSubmission(KernelCount=2) 1.00 0.62 0.63 0.96
BestWalkerNthSubmissionImmediate(KernelCount=2) 1.00 0.58 0.58 0.85
BestWalkerSubmission 1.00 0.62 0.62 0.96
BestWalkerSubmissionImmediate 1.00 0.63 0.62 0.96
BestWalkerSubmissionImmediateMultiCmdlists(cmdlistCount=2) 1.00 0.58 0.58 0.86
BestWalkerSubmissionImmediateMultiCmdlists(cmdlistCount=4) 1.00 0.70 0.70 0.83
BestWalkerSubmissionImmediateMultiCmdlists(cmdlistCount=8) 1.00 0.53 0.52 0.78
Log level 2 is the first "verbose level" for GuC, where the biggest
difference happens. Keep log level 3 for CONFIG_DRM_XE_DEBUG, but switch
to 1, i.e. GUC_LOG_LEVEL_NON_VERBOSE, for "normal" builds.

Wa_15015404425 only needs to be applied on PTL platforms with an A step
compute die. There is no way to map PCI revid to the compute die
stepping. The easiest way to figure out compute die stepping our end is
to map the media IP's stepping to the compute die. For PTL, compute die
has an A stepping if and only if the media IP's stepping is also A-step
(This relationship is determined on a per platform basis and just
happens to be this way on PTL).
In addition this workaround is a chicken-and-egg problem. Wa_15015404425
requires that all register reads be preceded by four dummy MMIO writes
(including during early driver init and even pre-OS firmware). The
driver needs to perform some MMIO reads during init which include the
GMD_ID register that contains the Media IPs stepping. To handle this in
the safest manner assume the workaround applies to all of PTL during
driver probe and deactivate the workaround after.
The overall solution becomes a set of two workarounds:
* 15015404425 - a Device OOB workaround that's always active for PTL
* 15015404425_disable - a GT OOB workaround that applies to PTL
platfroms with a B0 or later stepping
The first of these workarounds issues dummy MMIO writes we do when
reading registers. The second guards logic that disables the first once
we have the necessary information later in the probe process.
v2: rename SoC to device, avoid null pointer dereference, update commit
message.
v3: rebase
v5: move disable check into xe_device_probe to avoid linking in xe_wa

Once we have started a GT reset sequence, which includes stopping
GuC CTB communication, we should also cancel all ongoing H2G send-
recv requests, as either GuC is already dead, or due to imminent
reset GuC will not be able to reply, or due to internal cleanup
we will lose pending fences. With this we will report dedicated
-ECANCELED error instead of misleading -ETIME.

allocations.
v5:
- Drop process_mem tracking
- Set the gpu_id field to dev->primary->index (Lucas, Tvrtko)
- Formatting cleanup under 80 columns
v3:
- Use now configurable CONFIG_TRACE_GPU_MEM instead of adding a
per-driver Kconfig (Lucas)
v2:
- Use u64 as preferred by checkpatch (Tvrtko)
- Fix errors in comments/Kconfig description (Tvrtko)

There looks to be an issue in our compression handling when the BO pages
are very fragmented, where we choose to skip the identity map and
instead fall back to emitting the PTEs by hand when migrating memory,
such that we can hopefully do more work per blit operation. However in
such a case we need to ensure the src PTEs are correctly tagged with a
compression enabled PAT index on dgpu xe2+, otherwise the copy will
simply treat the src memory as uncompressed, leading to corruption if
the memory was compressed by the user.
To fix this pass along use_comp_pat into emit_pte() on the src side, to
indicate that compression should be considered.

This reverts commit fe0154cf8222d9e38c60ccc124adb2f9b5272371.
Seeing some unexplained random failures during LRC context switches with
indirect ring state enabled. The failures were always there, but the
repro rate increased with the addition of WA BB as a separate BO.
Commit 3a1edef8f4b5 ("drm/xe: Make WA BB part of LRC BO") helped to
reduce the issues in the context switches, but didn't eliminate them
completely.
Indirect ring state is not required for any current features, so disable
for now until failures can be root caused.

Our LMEM buffer objects are not cleared by default on alloc
and during VF provisioning we only setup LMTT PTEs for the
actually provisioned LMEM range. But beyond that valid range
we might leave some stale data that could either point to some
other VFs allocations or even to the PF pages.
Explicitly clear all new LMTT page to avoid the risk that a
malicious VF would try to exploit that gap.
While around add asserts to catch any undesired PTE overwrites
and low-level debug traces to track LMTT PT life-cycle.
