If we keep track of when the i915_request.sched.link is on the HW runlist, or in the priority queue we can simplify our interactions with the request (such as during rescheduling). This also simplifies the next patch where we introduce a new in-between list, for requests that are ready but neither on the run list or in the queue. v2: Update i915_sched_node.link explanation for current usage where it is a link on both the queue and on the runlists.

We need to allow concurrent intel_context_unpin, which means avoiding doing destructive operations like intel_ring_reset(). This was already fixed for intel_ring_unpin() in commit 0725d9a3 ("drm/i915/gt: Make intel_ring_unpin() safe for concurrent pint"), but I overlooked that execlists_context_unpin() also made the same mistake.

fbc_supported() is just a pointless wrapper for HAS_FBC(). Get rid of it. In places where we're operating on a specific plane we can replace this with a plane->has_fbc check to avoid doing anything for crtcs that don't even support fbc. Signed-off-by:

Add a debugfs subdirectory i915_params with all the i915 module parameters. This is a first step, with lots of boilerplate, and not much benefit yet. This will result in a new device specific debugfs directory at /sys/kernel/debug/dri/<N>/i915_params duplicating the module specific sysfs directory at /sys/module/i915/parameters/. Going forward, all users of the parameters should use the debugfs, with the module parameters being phased out. Add debugfs permissions to I915_PARAMS_FOR_EACH(). This duplicates the mode with module parameter sysfs, but the goal is to make the module parameters read-only initial values for device specific parameters. 0 mode will bypass debugfs creation. Use it for verbose_state_checks which will need special attention in follow-up work. Reviewed-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.

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.

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:

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:

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.
