Currently, we skip error capture upon forced preemption. We apply forced preemption when there is a higher priority request that should be running but is being blocked, and we skip inline error capture so that the preemption request is not further delayed by a user controlled capture -- extending the denial of service. However, preemption reset is also used for heartbeats and regular GPU hangs. By skipping the error capture, we remove the ability to debug GPU hangs. In order to capture the error without delaying the preemption request further, we can do an out-of-line capture by removing the guilty request from the execution queue and scheduling a worker to dump that request. When removing a request, we need to remove the entire context and all descendants from the execution queue, so that they do not jump past.

In order to support out-of-line error capture, we need to remove the active request from HW and put it to one side while a worker compresses and stores all the details associated with that request. (As that compression may take an arbitrary user-controlled amount of time, we want to let the engine continue running on other workloads while the hanging request is dumped.) Not only do we need to remove the active request, but we also have to remove its context and all requests that were dependent on it (both in flight, queued and future submission). Finally once the capture is complete, we need to be able to resubmit the request and its dependents and allow them to execute. v2: Replace stack recursion with a simple list. v3: Check all the parents, not just the first, when searching for a stuck ancestor!

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.

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.

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.

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.

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: Matt Roper <matthew.d.roper@intel.com> Signed-off-by: Stanislav Lisovskiy <stanislav.lisovskiy@intel.com> Closes: https://gitlab.freedesktop.org/drm/intel/issues/402Signed-off-by: Jani Nikula <jani.nikula@intel.com> Link: https://patchwork.freedesktop.org/patch/msgid/20200109220547.23817-1-stanislav.lisovskiy@intel.com

Instead of spreading multiple conditionals across the uC code to find out current mode of uC operation, start using predefined set of function pointers that reflect that mode. Begin with pair of init_hw/fini_hw functions that are responsible for uC hardware initialization and cleanup. v2: drop ops_none, use macro to generate ops helpers v3: reuse __uc_check_hw to avoid redundant comment v4: forward declare ops struct vs functions Signed-off-by: Michal Wajdeczko <michal.wajdeczko@intel.com> Cc: Joonas Lahtinen <joonas.lahtinen@linux.intel.com> Cc: Chris Wilson <chris@chris-wilson.co.uk> Cc: Daniele Ceraolo Spurio <daniele.ceraolospurio@intel.com> Reviewed-by: Chris Wilson <chris@chris-wilson.co.uk> Signed-off-by: Chris Wilson <chris@chris-wilson.co.uk> Link: https://patchwork.freedesktop.org/patch/msgid/20200110222723.14724-2-michal.wajdeczko@intel.com
