2022-11-02drm/i915: Fix cs timestamp frequency for ctg/elk/ilkVille Syrjälä1-2/+26
On ilk the UDW of TIMESTAMP increments every 1000 ns, LDW is mbz. In order to represent that we'd need 52 bits, but we only have 32 bits. Even worse most things want to only deal with 32 bits of timestamp. So let's just set up the timestamp frequency as if we only had the UDW. On ctg/elk 63:20 of TIMESTAMP increments every 1/4 ns, 19:0 are mbz. To make life simpler let's ignore the LDW and set up timestamp frequency based on the UDW only (increments every 1024 ns). v2: Rebase Signed-off-by: Ville Syrjälä <[email protected]> Link: https://patchwork.freedesktop.org/patch/msgid/[email protected] Reviewed-by: Lionel Landwerlin <[email protected]>

When i915_gem_object_release_mmap_offset() gets called by i915_ttm_move_notify(), it will release the mmap offset without grabbing the wakeref.

In order to support higher HDMI frequencies, users have to set the hdmi_enable_4kp60 parameter in their config.txt file. We were detecting this so far by calling clk_round_rate() on the core clock with the frequency we're supposed to run at when one of those modes is enabled. Whether or not the parameter was enabled could then be inferred by the returned rate since the maximum clock rate reported by the firmware was one of the side effect of setting that parameter. However, the recent clock rework we did changed what clk_round_rate() was returning to always return the minimum allowed, and thus this test wasn't reliable anymore. Let's use the new clk_get_max_rate() function to reliably determine the maximum rate allowed on that clock and fix the 4k@60Hz output.

2022-10-27drm/i915/guc: Support OA when Wa_16011777198 is enabledVinay Belgaumkar4-0/+104
On DG2, a w/a resets RCS/CCS before it goes into RC6. This breaks OA since OA does not expect engine resets during its use. Fix it by disabling RC6. v2: (Ashutosh) - Bring back slpc_unset_param helper - Update commit msg - Use with_intel_runtime_pm helper for set/unset v3: (Ashutosh) - Just use intel_uc_uses_guc_rc Signed-off-by: Vinay Belgaumkar <[email protected]> Signed-off-by: Umesh Nerlige Ramappa <[email protected]> Reviewed-by: Ashutosh Dixit <[email protected]> Signed-off-by: John Harrison <[email protected]> Link: https://patchwork.freedesktop.org/patch/msgid/[email protected]
2022-10-27drm/i915/perf: Save/restore EU flex counters across resetUmesh Nerlige Ramappa1-0/+10
If a drm client is killed, then hw contexts used by the client are reset immediately. This reset clears the EU flex counter configuration. If an OA use case is running in parallel, it would start seeing zeroed eu counter values following the reset even if the drm client is restarted. Save/restore the EU flex counter config so that the EU counters can be monitored continuously across resets. v2: - Save/restore eu flex config only for gen12, as for pre-gen12, these are saved and restored in the context image.

2022-10-27drm/i915/perf: Apply Wa_18013179988Umesh Nerlige Ramappa4-2/+39
OA reports in the OA buffer contain an OA timestamp field that helps user calculate delta between 2 OA reports. The calculation relies on the CS timestamp frequency to convert the timestamp value to nanoseconds. The CS timestamp frequency is a function of the CTC_SHIFT value in RPM_CONFIG0. In DG2, OA unit assumes that the CTC_SHIFT is 3, instead of using the actual value from RPM_CONFIG0. At the user level, this results in an error in calculating delta between 2 OA reports since the OA timestamp is not shifted in the same manner as CS timestamp. Also the periodicity of the reports is different from what the user configured because of mismatch in the CS and OA frequencies. The issue also affects MI_REPORT_PERF_COUNT command. To resolve this, return actual OA timestamp frequency to the user in i915_getparam_ioctl, so that user can calculate the right OA exponent as well as interpret the reports correctly.
