drm/i915: Revert 'guc_id' from i915_request tracepoint

2021-10-28T08:45:11Z

Avoid adding backend specific data to the tracepoints outside of the LOW_LEVEL_TRACEPOINTS kernel config protection. These bits of information are bound to change depending on the selected submission method per platform and are not necessarily possible to maintain in the future.

drm/amd/display: Fix deadlock when falling back to v2 from v3

2021-10-28T02:04:50Z

[Why] A deadlock in the kernel occurs when we fallback from the V3 to V2 add_topology_to_display or remove_topology_to_display because they both try to acquire the dtm_mutex but recursive locking isn't supported on mutex_lock(). [How] Make the mutex_lock/unlock more fine grained and move them up such that they're only required for the psp invocation itself.

drm/amd/display: Fallback to clocks which meet requested voltage on DCN31

2021-10-28T02:04:32Z

[WHY] On certain configs, SMU clock table voltages don't match which cause parser to behave incorrectly by leaving dcfclk and socclk table entries unpopulated. [HOW] Currently the function that finds the corresponding clock for a given voltage only checks for exact voltage level matches. In the case that no match gets found, parser now falls back to searching for the max clock which meets the requested voltage (i.e. its corresponding voltage is below requested).

drm/i915/dp: Skip the HW readout of DPCD on disabled encoders

2021-10-26T07:40:10Z

Reading out the DP encoders' DPCD during booting or resume is only required for enabled encoders: such encoders may be modesetted during the initial commit and the link training this involves depends on an initialized DPCD. For DDI encoders reading out the DPCD is skipped, do the same on pre-DDI platforms. Atm, the first DPCD readout without a sink connected - which is a likely scneario if the encoder is disabled - leaves intel_dp->num_common_rates at 0, which resulted in intel_dp_sync_state()->intel_dp_max_common_rate() in a intel_dp->common_rates[-1] access. This by definition results in an undefined behaviour, though to my best knowledge in all HW/compiler configurations it actually results in accessing the array item type value preceding the array. In this case the preceding value happens to be intel_dp->num_common_rates, which is 0, so this issue - by luck - didn't cause a user visible problem. Nevertheless it's still an undefined behaviour and in CONFIG_UBSAN builds leads to a kernel BUG() (which revealed this problem for us), hence CC:stable. A related problem in case the encoder is enabled but the sink is not connected or the DPCD readout fails is fixed by the next patch. v2: Amend the commit message describing the root cause of the CONFIG_UBSAN BUG().
