2023-08-23drm/i915: Fix HPD polling, reenabling the output poll work as neededImre Deak
After the commit in the Fixes: line below, HPD polling stopped working on i915, since after that change calling drm_kms_helper_poll_enable() doesn't restart drm_mode_config::output_poll_work if the work was stopped (no connectors needing polling) and enabling polling for a connector (during runtime suspend or detecting an HPD IRQ storm). After the above change calling drm_kms_helper_poll_enable() is a nop after it's been called already and polling for some connectors was disabled/re-enabled. Fix this by calling drm_kms_helper_poll_reschedule() added in the previous patch instead, which reschedules the work whenever expected.

2023-08-14drm/i915: fix display probe for IVB Q and IVB D GT2 serverJani Nikula
The current display probe is unable to differentiate between IVB Q and IVB D GT2 server, as they both have the same device id, but different subvendor and subdevice. This leads to the latter being misidentified as the former, and should just end up not having a display. However, the no display case returns a NULL as the display device info, and promptly oopses. As the IVB Q case is rare, and we're anyway moving towards GMD ID, handle the identification requiring subvendor and subdevice as a special case first, instead of unnecessarily growing the intel_display_ids[] array with subvendor and subdevice.

2023-08-14drm/i915/guc/slpc: Restore efficient freq earlierVinay Belgaumkar
This should be done before the soft min/max frequencies are restored. When we disable the "Ignore efficient frequency" flag, GuC does not actually bring the requested freq down to RPn. Specifically, this scenario- - ignore efficient freq set to true - reduce min to RPn (from efficient) - suspend - resume (includes GuC load, restore soft min/max, restore efficient freq) - validate min freq has been resored to RPn This will fail if we didn't first restore(disable, in this case) efficient freq flag before setting the soft min frequency. v2: Bring the min freq down to RPn when we disable efficient freq (Rodrigo) Also made the change to set the min softlimit to RPn at init. Otherwise, we were storing RPe there.

2023-08-10drm/i915/gt: Apply workaround 22016122933 correctlyJonathan Cavitt
WA_22016122933 was recently applied to all MeteorLake engines, which is simultaneously too broad (should only apply to Media engines) and too specific (should apply to all platforms that use the same media engine as MeteorLake). Correct this in cases where coherency settings are modified. There were also two additional places where the workaround was applied unconditionally. The change was confirmed as necessary for all platforms, so the workaround label was removed.

2023-08-10drm/i915: debug log when GMD ID indicates there's no displayJani Nikula
Debug log similar to the device id based identification of no display. Reviewed-by: Luca Coelho <luciano.coelho@intel.com> Signed-off-by: Jani Nikula <jani.nikula@intel.com> Link: https://patchwork.freedesktop.org/patch/msgid/20230804084600.1005818-2-jani.nikula@intel.com
2023-08-10drm/i915: fix display probe for IVB Q and IVB D GT2 serverJani Nikula
The current display probe is unable to differentiate between IVB Q and IVB D GT2 server, as they both have the same device id, but different subvendor and subdevice. This leads to the latter being misidentified as the former, and should just end up not having a display. However, the no display case returns a NULL as the display device info, and promptly oopses. As the IVB Q case is rare, and we're anyway moving towards GMD ID, handle the identification requiring subvendor and subdevice as a special case first, instead of unnecessarily growing the intel_display_ids[] array with subvendor and subdevice.

2023-08-08drm/i915/display: pre-initialize some values in probe_gmdid_display()Luca Coelho
When intel_display_device_probe() (and, subsequently, probe_gmdid_display()) returns, the caller expects ver, rel and step to be initialized. Since there's no way to check that there was a failure and no_display was returned without some further refactoring, pre-initiliaze all these values to zero to keep it simple and safe.

This should be done before the soft min/max frequencies are restored. When we disable the "Ignore efficient frequency" flag, GuC does not actually bring the requested freq down to RPn. Specifically, this scenario- - ignore efficient freq set to true - reduce min to RPn (from efficient) - suspend - resume (includes GuC load, restore soft min/max, restore efficient freq) - validate min freq has been resored to RPn This will fail if we didn't first restore(disable, in this case) efficient freq flag before setting the soft min frequency. v2: Bring the min freq down to RPn when we disable efficient freq (Rodrigo) Also made the change to set the min softlimit to RPn at init. Otherwise, we were storing RPe there.

2023-08-01drm/i915: Fix premature release of request's reusable memoryJanusz Krzysztofik
Infinite waits for completion of GPU activity have been observed in CI, mostly inside __i915_active_wait(), triggered by igt@gem_barrier_race or igt@perf@stress-open-close. Root cause analysis, based of ftrace dumps generated with a lot of extra trace_printk() calls added to the code, revealed loops of request dependencies being accidentally built, preventing the requests from being processed, each waiting for completion of another one's activity. After we substitute a new request for a last active one tracked on a timeline, we set up a dependency of our new request to wait on completion of current activity of that previous one. While doing that, we must take care of keeping the old request still in memory until we use its attributes for setting up that await dependency, or we can happen to set up the await dependency on an unrelated request that already reuses the memory previously allocated to the old one, already released. Combined with perf adding consecutive kernel context remote requests to different user context timelines, unresolvable loops of await dependencies can be built, leading do infinite waits. We obtain a pointer to the previous request to wait upon when we substitute it with a pointer to our new request in an active tracker, e.g. in intel_timeline.last_request. In some processing paths we protect that old request from being freed before we use it by getting a reference to it under RCU protection, but in others, e.g. __i915_request_commit() -> __i915_request_add_to_timeline() -> __i915_request_ensure_ordering(), we don't. But anyway, since the requests' memory is SLAB_FAILSAFE_BY_RCU, that RCU protection is not sufficient against reuse of memory. We could protect i915_request's memory from being prematurely reused by calling its release function via call_rcu() and using rcu_read_lock() consequently, as proposed in v1. However, that approach leads to significant (up to 10 times) increase of SLAB utilization by i915_request SLAB cache. Another potential approach is to take a reference to the previous active fence. When updating an active fence tracker, we first lock the new fence, substitute a pointer of the current active fence with the new one, then we lock the substituted fence. With this approach, there is a time window after the substitution and before the lock when the request can be concurrently released by an interrupt handler and its memory reused, then we may happen to lock and return a new, unrelated request. Always get a reference to the current active fence first, before replacing it with a new one. Having it protected from premature release and reuse, lock it and then replace with the new one but only if not yet signalled via a potential concurrent interrupt nor replaced with another one by a potential concurrent thread, otherwise retry, starting from getting a reference to the new current one. Adjust users to not get a reference to the previous active fence themselves and always put the reference got by __i915_active_fence_set() when no longer needed. v3: Fix lockdep splat reports and other issues caused by incorrect use of try_cmpxchg() (use (cmpxchg() != prev) instead) v2: Protect request's memory by getting a reference to it in favor of delegating its release to call_rcu() (Chris) Closes: https://gitlab.freedesktop.org/drm/intel/-/issues/8211 Fixes: df9f85d8582e ("drm/i915: Serialise i915_active_fence_set() with itself") Suggested-by: Chris Wilson <chris@chris-wilson.co.uk> Signed-off-by: Janusz Krzysztofik <janusz.krzysztofik@linux.intel.com> Cc: <stable@vger.kernel.org> # v5.6+ Reviewed-by: Andi Shyti <andi.shyti@linux.intel.com> Signed-off-by: Andi Shyti <andi.shyti@linux.intel.com> Link: https://patchwork.freedesktop.org/patch/msgid/20230720093543.832147-2-janusz.krzysztofik@linux.intel.com (cherry picked from commit 946e047a3d88d46d15b5c5af0414098e12b243f7) Signed-off-by: Tvrtko Ursulin <tvrtko.ursulin@intel.com>
