Register 0x9424 is not replicated on any platform, so it shouldn't be declared with REG_MCR(). Declaring it with _MMIO() is basically duplicate of the GEN7 version, so just remove the GEN8 and change all the callers to use the right functions. Old versions of the gen8 bspec page used to contain a table with MCR registers, apparently implying 0x9400 - 0x94ff registers were replicated. However that table went away and there is no information related to the ranges for gen8 anymore. Moreover the current behavior of the driver wouldn't do anything special for 0x9424 since there is no equivalent table in intel_gt_mcr.c: the driver would just fallback to intel_uncore_{read,write}(). Therefore, do not care about the possible special case for gen8 and just use the register as non-MCR for all the platforms. One place doing read + write is also converted to intel_uncore_rmw(). v2: Reword commit message adding the justification wrt gen8 Fixes: a9e69428 ("drm/i915: Define MCR registers explicitly") Cc: Balasubramani Vivekanandan <balasubramani.vivekanandan@intel.com> Cc: Rodrigo Vivi <rodrigo.vivi@intel.com> Cc: Gustavo Sousa <gustavo.sousa@intel.com> Cc: Matt Atwood <matthew.s.atwood@intel.com> Cc: Ashutosh Dixit <ashutosh.dixit@intel.com> Signed-off-by:Lucas De Marchi <lucas.demarchi@intel.com> Reviewed-by:

The UNSLICE_UNIT_LEVEL_CLKGATE register programmed by this workaround has 'BUS' style reset, indicating that it does not lose its value on engine resets. Furthermore, this register is part of the GT forcewake domain rather than the RENDER domain, so it should not be impacted by RCS engine resets. As such, we should implement this on the GT workaround list rather than an engine list. Bspec: 19219 Fixes: 3551ff92 ("drm/i915/gen11: Moving WAs to rcs_engine_wa_init()") Signed-off-by:

XEHPC_LNCFMISCCFGREG0 and XEHPC_L3SCRUB are both in MCR register ranges on PVC (with HALFBSLICE and L3BANK replication respectively), so they should be explicitly declared as MCR registers and use MCR-aware workaround handlers. The workarounds/tuning settings should still be applied properly on PVC even without the MCR annotation, but readback verification on CONFIG_DRM_I915_DEBUG_GEM builds could potentitally give false positive "workaround lost on load" warnings on parts fused such that a unicast read targets a terminated register instance.

During module load the punit might still be busy with its booting routines. During this time we try to communicate with it but we fail because we don't receive any feedback from it and we return immediately with a -EINVAL fatal error. At this point the driver load is "dramatically" aborted. The following error message notifies us about it. i915 0000:4d:00.0: drm_WARN_ON_ONCE(timeout_base_ms > 3) It would be enough to wait a little in order to give the punit the chance to come up bright and shiny, ready to interact with the driver. Wait up 10 seconds for the punit to settle and complete any outstanding transactions upon module load. If it still fails try again with a longer timeout, 180s, 3 minutes. If it still fails then return -EPROBE_DEFER, in order to give the punit a second chance. Even if these timers might look long, we should consider that the punit, depending on the platforms, might need long times to complete its routines. Besides we want to try anything possible to move forward before deciding to abort the driver's load. The issue has been reported in: https://gitlab.freedesktop.org/drm/intel/-/issues/7814 The changes in this patch are valid only and uniquely during boot. The common transactions with the punit during the driver's normal operation are not affected. Signed-off-by:

DSM granularity is 1MB so make sure we stick to that. The address set by firmware in GEN12_DSMBASE in driver initialization doesn't mean "anything above that and until end of lmem is part of DSM". In fact, there may be a few KB that is not part of DSM on the end of lmem. How large is that space is platform-dependent, but since it's always less than the DSM granularity, it can be simplified by simply aligning the size down. v2: replace "1 * SZ_1M" with SZ_1M (Andrzej). v3: reword commit message to explain why the round down is needed (Lucas) Cc: Matthew Auld <matthew.auld@intel.com> Suggested-by:Nirmoy Das <nirmoy.das@intel.com> Reviewed-by:

Wa_22011802037 requires waiting for an engine-specific register to clear. A missing entry for GSC engine in the register table is flagged as a drm_err.

Engine resets are supposed to never fail. But in the case when one does (due to unknown reasons that normally come down to a missing w/a), it is useful to get as much information out of the system as possible. Given that the GuC intentionally dies on such a situation, it is not possible to get a guilty context notification back. So do a manual search instead. Given that GuC is dead, this is safe because GuC won't be changing the engine state asynchronously. v2: Change comment to be less alarming (Tvrtko) Signed-off-by:

A hang situation has been observed where the only requests on the context were either completed or not yet started according to the breaadcrumbs.

John Harrison authored
There was a report of error captures occurring without any hung context being indicated despite the capture being initiated by a 'hung context notification' from GuC. The problem was not reproducible. However, it is possible to happen if the context in question has no active requests. For example, if the hang was in the context switch itself then the breadcrumb write would have occurred and the KMD would see an idle context. In the interests of attempting to provide as much information as possible about a hang, it seems wise to include the engine info regardless of whether a request was found or not. As opposed to just prentending there was no hang at all. So update the error capture code to always record engine information if a context is given. Which means updating record_context() to take a context instead of a request (which it only ever used to find the context anyway). And split the request agnostic parts of intel_engine_coredump_add_request() out into a seaprate function. v2: Remove a duplicate 'if' statement (Umesh) and fix a put of a null pointer. v3: Tidy up request locking code flow (Tvrtko) v4: Pull in improved info message from next patch and fix up potential leak of GuC register state (Daniele) Signed-off-by:

The debugfs dump of requests was confused about what state requires the execlist lock versus the GuC lock. There was also a bunch of duplicated messy code between it and the error capture code. So refactor the hung request search into a re-usable function. And reduce the span of the execlist state lock to only the execlist specific code paths. In order to do that, also move the report of hold count (which is an execlist only concept) from the top level dump function to the lower level execlist specific function. Also, move the execlist specific code into the execlist source file. v2: Rename some functions and move to more appropriate files (Daniele). v3: Rename new execlist dump function (Daniele) Fixes: dc0dad36 ("drm/i915/guc: Fix for error capture after full GPU reset with GuC") Signed-off-by:

When GuC support was added to error capture, the reference counting around the request object was broken. Fix it up. The context based search manages the spinlocking around the search internally. So it needs to grab the reference count internally as well. The execlist only request based search relies on external locking, so it needs an external reference count but within the spinlock not outside it. The only other caller of the context based search is the code for dumping engine state to debugfs. That code wasn't previously getting an explicit reference at all as it does everything while holding the execlist specific spinlock. So, that needs updaing as well as that spinlock doesn't help when using GuC submission. Rather than trying to conditionally get/put depending on submission model, just change it to always do the get/put. v2: Explicitly document adding an extra blank line in some dense code (Andy Shevchenko). Fix multiple potential null pointer derefs in case of no request found (some spotted by Tvrtko, but there was more!). Also fix a leaked request in case of !started and another in __guc_reset_context now that intel_context_find_active_request is actually reference counting the returned request. v3: Add a _get suffix to intel_context_find_active_request now that it grabs a reference (Daniele). v4: Split the intel_guc_find_hung_context change to a separate patch and rename intel_context_find_active_request_get to intel_context_get_active_request (Tvrtko). v5: s/locking/reference counting/ in commit message (Tvrtko) Fixes: dc0dad36 ("drm/i915/guc: Fix for error capture after full GPU reset with GuC") Fixes: 573ba126 ("drm/i915/guc: Capture error state on context reset") Signed-off-by:

These registers have only been used for some dg2/xehpsdv workarounds, so this fix is mostly just for consistency/future-proofing; even lacking the MCR annotation, workarounds will always be properly applied in a multicast manner on these platforms.

Workaround Wa_18018781329 has applied to several recent Xe_HP-based platforms. However there are some extra gotchas to implementing this properly for MTL that we need to take into account: * Due to the separation of media and render/compute into separate GTs, this workaround needs to be implemented on each GT, not just the primary GT. Since each class of register only exists on one of the two GTs, we should program the appropriate registers on each GT. * As with past Xe_HP platforms, the registers on the primary GT (Xe_LPG IP) are multicast/replicated registers and should be handled with the MCR-aware functions. However the registers on the media GT (Xe_LPM+ IP) are regular singleton registers and should _not_ use MCR handling. We need to create separate register definitions for the Xe_HP multicast form and the Xe_LPM+ singleton form and use each in the appropriate place. * Starting with MTL, workarounds documented by the hardware teams are technically associated with IP versions/steppings rather than top-level platforms. That means we should take care to check the media IP version rather than the graphics IP version when deciding whether the workaround is needed on the Xe_LPM+ media GT (in this case the workaround applies to both IPs and the stepping bounds are identical, but we should still write the code appropriately to set a proper precedent for future workaround implementations). * It's worth noting that the GSC register and the CCS register are defined with the same MMIO offset (0xCF30). Since the CCS is only relevant to the primary GT and the GSC is only relevant to the media GT there isn't actually a clash here (the media GT automatically adds the additional 0x380000 GSI offset). However there's currently a glitch in the bspec where the CCS register doesn't show up at all and the GSC register is listed as existing on both GTs. That's a known documentation problem for several registers with shared GSC/CCS offsets; rest assured that the CCS register really does still exist.

Register reset characteristics (i.e., whether the register maintains or loses its value on engine reset) is an important factor that determines which wa_list we want to add workarounds to. We recently found out that the bspec documentation for the Xe_HP's "GAM" registers in the 0xC800 - 0xCFFF range was misleading; these registers do not actually lose their value on engine resets as the documentation implied. This means there's no need to re-apply workarounds touching these registers after a reset, and the corresponding workarounds should be moved from the 'engine' lists back to the 'gt' list. v2: - Don't add Wa_18018781329 to xehpsdv; the original condition didn't include that platform. (Gustavo) - Move the MTL code to the GT function as-is for now; we'll take care of the additional fixes needed in a follow-up patch.
