TGL has now a table for RBR and HBR and another table for HBR2 over combo phys. The HBR2 one has some small changes comparing to the ICL one, so adding two new tables and adding a function to return TGL combo phy tables. v2: - reordered the tgl_combo_phy_ddi_translations_dp_hbr2 to reduce diff (Matt) - removed definition of rates, kept using raw number(Jani and Ville) - changed code to use icl_get_combo_buf_trans() for non-DP as those are equal between TGL and ICL(Matt) BSpec: 49291 Cc: Lucas De Marchi <lucas.demarchi@intel.com> Cc: Matt Roper <matthew.d.roper@intel.com> Cc: Ville Syrjälä <ville.syrjala@linux.intel.com> Cc: Jani Nikula <jani.nikula@intel.com> Signed-off-by:

intel_prepare_plane_fb() will always pin plane_state->hw.fb whenever it is present. We copy that from the master plane to the slave plane, but we fail to copy the corresponding ggtt view. Thus when it comes time to pin the slave plane's fb we use some stale ggtt view left over from the last time the plane was used as a non-slave plane. If that previous use involved 90/270 degree rotation or remapping we'll try to shuffle the pages of the new fb around accordingingly. However the new fb may be backed by a bo with less pages than what the ggtt view rotation/remapped info requires, and so we we trip a GEM_BUG(). Steps to reproduce on icl: 1. plane 1: whatever plane 6: largish !NV12 fb + 90 degree rotation 2. plane 1: smallish NV12 fb plane 6: make invisible so it gets slaved to plane 1 3.

On suspend, the rc6 residency counters (stored in HW registers) will be lost and cleared. However, we keep track of the rc6 residency to provide a continuous 64b sampling, and if we see the HW value go backwards, we assume it overflowed and add on 32b/40b -- an interesting artifact when sampling across suspend.

The rc6 residency starts ticking from 0 from BIOS POST, but the kernel starts measuring the time from its boot. If we start measuruing I915_PMU_RC6_RESIDENCY while the GT is idle, we start our sampling from 0 and then upon first activity (park/unpark) add in all the rc6 residency since boot. After the first park with the sampler engaged, the sleep/active counters are aligned. v2: With a wakeref to be sure Closes: https://gitlab.freedesktop.org/drm/intel/issues/973 Fixes: df6a4205 ("drm/i915/pmu: Ensure monotonic rc6") Signed-off-by:

Currently, we reset the timer after a pre-eemption event. This has the side-effect that the timeslice runs into the second context after the first is completed after a normal promotion event, causing the second context to be swapped out early and switched for a third context. To be more fair, we want to reset the clock after promotion as well. Signed-off-by:

Life is usually easier when we pass around intel_ types instead of drm_ types. In this case it might not be, but I think being consistent is a good thing anyway.

There seems to be some undocumented bandwidth bottleneck/dependency which scales with CDCLK, causing FIFO underruns when CDCLK is too low, even when it's correct from BSpec point of view. Currently for TGL platforms we calculate min_cdclk initially based on pixel_rate divided by 2, accounting for also plane requirements, however in some cases the lowest possible CDCLK doesn't work and causing the underruns. We've found experimentally that raising cdclk to at least pixel_rate (rather than pixel_rate/2) eliminates these underruns, so let's use this as a temporary workaround until the hardware team can suggest a more precise remedy. Explicitly stating here that this seems to be currently rather a Hack, than final solution. v2: Use clamp operation instead of min(Matt Roper) v3: - Fixed commit message(Matt Roper) - Now using pixel_rate instead of max_cdclk(Jani Nikula) - Switched to max from clamp(Ville Syrjälä) Hopefully this hybrid satisfies everyone :) Reviewed-by:Stanislav Lisovskiy <stanislav.lisovskiy@intel.com> Closes: https://gitlab.freedesktop.org/drm/intel/issues/402Signed-off-by:

We need to hold the runtime-pm wakeref to update the global PTEs (as they exist behind a PCI BAR). However, some systems invoke ACPI during runtime resume and so require allocations, which is verboten inside the vm->mutex. Ergo, we must not use intel_runtime_pm_get() inside the mutex, but lift the call outside. Closes: https://gitlab.freedesktop.org/drm/intel/issues/958Signed-off-by:

Parsing the i2c element is mainly done to transfer the payload from the MIPI sequence block to the relevant slave device. In some cases, the commands that are part of the payload can be used to turn on the backlight. This patch is actually a refactored version of this old patch: https://lists.freedesktop.org/archives/intel-gfx/2014-December/056897.html In addition to the refactoring, the original patch is augmented by looking up the i2c bus from ACPI NS instead of relying on the bus number provided in the VBT. This patch was tested on Aava Mobile's Inari 10 tablet. It enabled turning on the backlight by transferring the payload to the device. v2: - Add DRM_DEV_ERROR for invalid adapter and failed transfer and also drop the DRM_DEBUG that existed originally. (Hans) - Add two gotos instead of one to clean things up properly. v3: - Identify the device on which this patch was tested in the commit message (Ville) Cc: Hans de Goede <hdegoede@redhat.com> Cc: Nabendu Maiti <nabendu.bikash.maiti@intel.com> Cc: Matt Roper <matthew.d.roper@intel.com> Cc: Bob Paauwe <bob.j.paauwe@intel.com> Cc: Ville Syrjälä <ville.syrjala@linux.intel.com> Reviewed-by:

In the near future, we will want to start a GPU error capture from a new context, from inside the softirq region of a forced preemption. To do so requires us to break up the monolithic error capture to provide new entry points with finer control; in particular focusing on one engine/gt, and being able to compose an error state from little pieces of HW capture.

Currently we first to try to unbind the VMA (and lazily rebind on next use) as an optimisation during restore_ggtt_mappings. Ideally, the only objects in the GGTT upon resume are the pinned kernel objects which can't be unbound and need to be restored. As the unbind interferes with the plan to mark those objects as active for error capture, forgo the optimisation. Signed-off-by:
