2020-06-23drm/i915/dp_mst: Move clearing the ACT sent flag closer to its pollingImre Deak
During transcoder enabling we'll configure the transcoder in MST mode and enable the VC payload allocation, which will start the ACT sequence. Before waiting for the ACT sequence completion, we need to clear the ACT sent flag, but based on the above we can do this right before enabling the transcoder. For clarity, move the flag clearing closer to where we wait for it. While at it also factor out some common code.

2020-06-23drm/i915/dp_mst: Disable link training fallback on MST linksImre Deak
During the initial probing of an MST sink, MST core will determine the sink's link bandwidth based on its own version of the sink link rate/lane count caps it reads from the DPCD. At a later point (after probing and 1 or more modesets) i915 may limit the link parameters wrt. the original source/sink common caps above due to link training failures during a modeset and the resulting link training fallback logic. Based on the above a modeset following another modeset with a link training error will compute the i915 HW specific and DP protocol timing parameters (data/link M/N and MST TU values) taking into account only the unlimited source/sink common caps, but not taking into account the fallback limits. This will also let DRM core oversubscribe the actual link bandwidth during the MST payload allocation. Prevent the above problem by disabling the link training fallback on MST links for now, until the MST probe time initialization and the MST compute config logic can deal with changing link parameters. The misconfigured timings lead at least to a 'Timed out waiting for DP idle patterns' error. v2: (Ville) - Print link training error message on the MST path too. - Clarify the problem in the commit log.

2020-06-23drm/i915/tgl+: Use the correct DP_TP_* register instances in MST encodersImre Deak
MST encoders must use the master MST transcoder's DP_TP_STATUS and DP_TP_CONTROL registers. Atm, during the HW readout of an MST encoder connected to a slave transcoder we reset these register addresses in intel_dp::regs.dp_tp_* to the slave transcoder's DP_TP_* register addresses incorrectly; fix this. One example where the above overwite happens is the encoder HW state validation after enabling multiple streams; see intel_dp_mst_enc_get_config(). After that during disabling any stream we'll get a 'Timed out waiting for ACT sent when disabling' error, due to reading from the incorrect DP_TP_STATUS register. This change replaces https://patchwork.freedesktop.org/patch/369577/?series=78193&rev=1 which just papered over the problem. v2: - Correct the failure scenario in the commit log.

2020-06-22drm/i915/params: switch to device specific parametersJani Nikula
Start using device specific parameters instead of module parameters for most things. The module parameters become the immutable initial values for i915 parameters. The device specific parameters in i915->params start life as a copy of i915_modparams. Any later changes are only reflected in the debugfs. The stragglers are: * i915.force_probe and i915.modeset. Needed before dev_priv is available. This is fine because the parameters are read-only and never modified. * i915.verbose_state_checks. Passing dev_priv to I915_STATE_WARN and I915_STATE_WARN_ON would result in massive and ugly churn. This is handled by not exposing the parameter via debugfs, and leaving the parameter writable in sysfs. This may be fixed up in follow-up work. * i915.inject_probe_failure. Only makes sense in terms of the module, not the device. This is handled by not exposing the parameter via debugfs. v2: Fix uc i915 lookup code (Michał Winiarski) Cc: Juha-Pekka Heikkilä <juha-pekka.heikkila@intel.com> Cc: Venkata Sandeep Dhanalakota <venkata.s.dhanalakota@intel.com> Cc: Michał Winiarski <michal.winiarski@intel.com> Reviewed-by: Rodrigo Vivi <rodrigo.vivi@intel.com> Acked-by: Michał Winiarski <michal.winiarski@intel.com> Signed-off-by: Jani Nikula <jani.nikula@intel.com> Link: http://patchwork.freedesktop.org/patch/msgid/20200618150402.14022-1-jani.nikula@intel.com

2020-06-20drm/i915/gt: Replace manual kmap_atomic() with pin_map for renderstateChris Wilson
We only emit the renderstate once now during module load, it is no longer a concern that we are delaying context creation and so do not need to so eagerly optimise. Since the last time we have looked at the renderstate, we have a pin_map / flush_map facility that supports simple single mappings, replacing the open-coded kmap_atomic() and prepare_write. As it should be a single page, of which we only write a small portion, we stick to a simple WB [kmap] and use clflush on !llc platforms, rather than creating a temporary WC vmapping for the single page.

2020-06-19drm/panfrost: Fix inbalance of devfreq record_busy/idle()Steven Price
The calls to panfrost_devfreq_record_busy() and panfrost_devfreq_record_idle() must be balanced to ensure that the devfreq utilisation is correctly reported. But there are two cases where this doesn't work correctly. In panfrost_job_hw_submit() if pm_runtime_get_sync() fails or the WARN_ON() fires then no call to panfrost_devfreq_record_busy() is made, but when the job times out the corresponding _record_idle() call is still made in panfrost_job_timedout(). Move the call up to ensure that it always happens. Secondly panfrost_job_timedout() only makes a single call to panfrost_devfreq_record_idle() even if it is cleaning up multiple jobs. Move the call inside the loop to ensure that the number of _record_idle() calls matches the number of _record_busy() calls.

Compared to its predecessors, the PX30 VOP has a different register layout for enabling per-pixel alpha. Instead of src_alpha_ctl and dst_alpha_ctl, there is a single alpha control register. This register takes some fields from src_alpha_ctl, but with a different layout. Add support for the required fields to the PX30 VOP window descriptions, which makes per-pixel-alpha formats behave correctly.

2020-06-17drm/i915/selftests: Check preemption rollback of different ring queue depthsChris Wilson
Like live_unlite_ring, but instead of simply looking at the impact of intel_ring_direction(), check that preemption more generally works with different depths of queued requests in the ring.

2020-06-17drm/i915/selftests: Exercise far preemption rollbacksChris Wilson
Not too long ago, we realised we had issues with a rolling back a context so far for a preemption request we considered the resubmit not to be a rollback but a forward roll. This means we would issue a lite restore instead of forcing a full restore, continuing execution of the old requests rather than causing a preemption. Add a selftest to exercise such a far rollback, such that if we were to skip the full restore, we would execute invalid instructions in the ring and hang. Note that while I was able to confirm that this causes us to do a lite-restore preemption rollback (with commit e36ba817fa96 ("drm/i915/gt: Incrementally check for rewinding") disabled), it did not trick the HW into rolling past the old RING_TAIL. Myybe on other HW.
