Commit 50357944 ("drm/i915/gsc: Mark internal GSC engine with reserved uabi class") made the GSC0 engine not have a valid uabi class and so broke the engine reset counting, which in turn was made class based in cb823ed9 ("drm/i915/gt: Use intel_gt as the primary object for handling resets"). Despite the title and commit text of the latter is not mentioning it (and has left the storage array incorrectly sized), tracking by class, despite it adding aliasing in hypthotetical multi-tile systems, is handy for virtual engines which for instance do not have a valid engine->id. Therefore we keep that but just change it to use the internal class which is always valid. We also add a helper to increment the count, which aligns with the existing getter. What was broken without this fix were out of bounds reads every time a reset would happen on the GSC0 engine, or during selftests when storing and cross-checking the counts in igt_live_test_begin and igt_live_test_end.

Noticed that the hangcheck selftest is submitting a non-preemptoble spinner. That means that even if the GuC does not die, the heartbeat will still kick in and trigger a reset. Which is rather defeating the purpose of the test - to verify that the heartbeat will kick in if the GuC itself has died. The test is deliberately killing the GuC, so it should never hit the case of a non-dead GuC. But it is not impossible that the kill might fail at some future point due to other driver re-work. So, make the spinner pre-emptible. That way the heartbeat can get through if the GuC is alive and context switching. Thus a reset only happens if the GuC dies. Thus, if the kill should stop working the test will now fail rather than claim to pass. Signed-off-by:

The GSC CS is not exposed to the user, so we skipped assigning a uabi class number for it. However, the trace logs use the uabi class and instance to identify the engine, so leaving uabi class unset makes the GSC CS show up as the RCS in those logs. Given that the engine is not exposed to the user, we can't add a new case in the uabi enum, so we insted internally define a kernel internal class as -1. At the same time remove special handling for the name and complete the uabi_classes array so internal class is automatically correctly assigned. Engine will show as 65535:0 other0 in the logs/traces which should be unique enough. v2: * Fix uabi class u8 vs u16 type confusion. Signed-off-by:

On MTL, the HuC is only supported on the media GT, so our validation check on the module parameter detects an inconsistency on the root GT (the modparams asks to enable HuC, but the support is not there) and prints the following info message: [drm] GT0: Incompatible option enable_guc=3 - HuC is not supported! This can be confusing to the user and make them think that something is wrong when it isn't, so we need to silence it. Given that any platform that supports HuC also supports GuC, if a user tries to enable HuC on a platform that really doesn't support it they'll already see a message about GuC not being supported, so instead of just silencing the HuC message on newer platforms we can just get rid of it entirely.

At the moment memory region names are a bit too varied and too inconsistent to be used for ABI purposes, like for upcoming fdinfo memory stats. System memory can be either system or system-ttm. Local memory has the instance number appended, others do not. Not only incosistent but thi kind of implementation detail is uninteresting for intended users of fdinfo memory stats. Add a stable name always formed as $type$instance. Could have chosen a different stable scheme, but I think any consistent and stable scheme should do just fine. Signed-off-by:

This workaround is primarily implemented by the BIOS. However if the BIOS applies the workaround it will reserve a small piece of our DSM (which should be at the top, right below the WOPCM); we just need to keep that region reserved so that nothing else attempts to re-use it. v2: Declare regs in intel_gt_regs.h (Matt Roper) v3: Shift WA implementation before calculation of *base (Matt Roper) v4: - Change condition gscpmi base to be fall in DSM range.(Matt Roper) Signed-off-by:
