[FOR_CI 00/15] Execlist based Engine reset patches

[Arun Siluvery]

This series implements Execlist based engine reset feature which is a
lightweight GPU reset as it only resets affected engine instead of all
engines.

This is mainly for testing.

Arun Siluvery (13):
  drm/i915: Update i915.reset to handle engine resets
  drm/i915/tdr: Separate reset bit encoding from reset counter
  drm/i915/tdr: Update reset_in_progress to account for engine reset
  drm/i915/tdr: Modify error handler for per engine hang recovery
  drm/i915/tdr: Identify and retire hung request
  drm/i915/tdr: Restart submission after engine reset
  drm/i915/tdr: Add support for per engine reset recovery
  drm/i915: Update wait_request to consider engine reset
  drm/i915: Port of Added scheduler support to __wait_request() calls
  drm/i915/tdr: Add engine reset count to error state
  drm/i915/tdr: Export reset count info to debugfs
  drm/i915/tdr: Enable Engine reset and recovery support
  drm/i915: Disable GuC submission for testing Engine reset patches

Mika Kuoppala (1):
  drm/i915: Skip reset request if there is one already

Tomas Elf (1):
  drm/i915: Reinstate hang recovery work queue.
