Instead, we see the completion event of the currently active request [ff84:45155] but at the time of processing that event, the breadcrumb has not yet been written. Though by the time we do print out the debug info, the seqno write of ff84:45156 has landed! Therefore there is a serialisation problem between the seqno writes and CS events, not just between the CS buffer and its head/tail pointers as previously observed on Icelake. This is not a huge problem, as we don't strictly rely on the breadcrumb to determine HW activity, but it may indicate that interrupt delivery is before the seqno write, aka bringing back the plague of missed interrupts from yesteryear. However, there is no indication of this wider problem, so let's just flush the seqno read before reporting an error. If it persists after the fresh read we can worry again.

Upon a GPU reset, we copy the default context image over top of the guilty image. This will rollback the CTX_TIMESTAMP register to before our value of ce->runtime.last. Reset both back to 0 so that we do not encounter an underflow on the next schedule out after resume. This should not be a huge issue in practice, as hangs should be rare in correct code.

Use a separate array allocation for the execbuf vma, so that we can track their lifetime independently from the copy of the user arguments. With luck, this has a secondary benefit of splitting the malloc size to within reason and avoid vmalloc. The downside is that we might require two separate vmallocs -- but much less likely. In the process, this prevents a memory leak on the ww_mutex error unwind. Closes: https://gitlab.freedesktop.org/drm/intel/-/issues/1390Signed-off-by:

We wish that the scheduler emit the context modification commands prior to enabling the oa_config, for which we must explicitly inform it of the ordering constraints. This is especially important as we now wait for the final oa_config setup to be completed and as this wait may be on a distinct context to the state modifications, we need that command packet to be always last in the queue. We borrow the i915_active for its ability to track multiple timelines and the last dma_fence on each; a flexible dma_resv. Keeping track of each dma_fence is important for us so that we can efficiently schedule the requests and reprioritise as required. Reported-by:

In what seems remarkably similar to the w/a required to not reload an idle context with HEAD==TAIL, it appears we must prevent the HW from switching to an idle context in ELSP[1], while simultaneously trying to preempt the HW to run another context and a continuation of the idle context (which is no longer idle). We can achieve this by preventing the context from completing while we reload a new ELSP (by applying ring_set_paused(1) across the whole of dequeue), except this eventually fails due to a lite-restore into a waiting semaphore does not generate an ACK. Instead, we try to avoid making the GPU do anything too challenging and not submit a new ELSP while the interrupts + CSB events appear to have fallen behind the completed contexts. We expect it to catch up shortly so we queue another tasklet execution and hope for the best. Closes: https://gitlab.freedesktop.org/drm/intel/issues/1501Signed-off-by:

Userptr causes lockdep to complain when we are using the aliasing-ppgtt (and ggtt, but for that it is rightfully so to complain about) in that when we revoke the userptr we take a mutex which we also use to revoke the mmaps. However, we only revoke mmaps for GGTT bindings and we never allow userptr to create a GGTT binding so the warning should be false and is simply caused by our conflation of the aliasing-ppgtt with the ggtt. So lets try treating the binding into the aliasing-ppgtt as a separate lockclass from the ggtt. The downside is that we are deliberately suppressing lockdep;s ability to warn us of cycles.

Commit 632f3ab9 ("drm/i915/audio: add codec wakeup override enabled/disable callback"), added logic to toggle Codec Wake on gen9. This is used by audio driver when it resets the HDA controller. It seems explicit toggling of the wakeline can help to fix problems with probe failing on some gen12 platforms. And based on specs, there is no reason why this programming sequence should not be applied to all gen9+ platforms. No side-effects are seen on gen10/11. So apply the wake-logic to all gen9+ platforms. Link: https://github.com/thesofproject/linux/issues/1847Signed-off-by:

We're about to introduce an options to open the perf stream, giving the user ability to configure how often it wants the kernel to poll the OA registers for available data.

A recent commit in clang added -Wtautological-compare to -Wall, which is enabled for i915 after -Wtautological-compare is disabled for the rest of the kernel so we see the following warning on x86_64: ../drivers/gpu/drm/i915/gem/i915_gem_execbuffer.c:1433:22: warning: result of comparison of constant 576460752303423487 with expression of type 'unsigned int' is always false [-Wtautological-constant-out-of-range-compare] if (unlikely(remain > N_RELOC(ULONG_MAX))) ~~~~~~~~~~~~~~~~^~~~~~~~~~~~~~~~~~~~~ ../include/linux/compiler.h:78:42: note: expanded from macro 'unlikely' # define unlikely(x) __builtin_expect(!!(x), 0) ^ 1 warning generated.

Cast remain to unsigned long, which keeps the generated code the same (verified with clang-11 on x86_64 and GCC 9.2.0 on x86 and x86_64) and the warning is silenced so we can catch more potential issues in the future.

Daniele Ceraolo Spurio authored
We currently initialize HuC support based on GuC being enabled in modparam; this means that huc_is_supported() can return false on HW that does have a HuC when enable_guc=0. The rationale for this behavior is that HuC requires GuC for authentication and therefore is not supported by itself. However, we do not allow defining HuC fw wthout GuC fw and selecting HuC in modparam implicitly selects GuC as well, so we can't actually hit a scenario where HuC is selected alone. Therefore, we can flip the support check to reflect the HW capabilities and fw availability, which is more intuitive and will make it cleaner to log HuC the difference between not supported in HW and not selected. Removing the difference between GuC and HuC also allows us to simplify the init_early, since we don't need to differentiate the support based on the type of uC. Signed-off-by:

When registering debugfs files the intel gt debugfs library forces a 'struct *gt' private data on the caller. To be open to different usages make the new "intel_gt_debugfs_register_files()"[*] function more generic by converting the 'struct *gt' pointer to a 'void *' type. I take the chance to rename the functions by using "intel_gt_" as prefix instead of "debugfs_", so that "debugfs_gt_register_files()" becomes "intel_gt_debugfs_register_files()". Signed-off-by:
