      drm/i915: Always backoff after a drm_modeset_lock() deadlock · ee6df569
      Chris Wilson authored
      If drm_modeset_lock() reports a deadlock it sets the ctx->contexted
      field and insists that the caller calls drm_modeset_backoff() or else it
      generates a WARN on cleanup.

      drm/i915: Program EXT2 GC MAX registers · 502da13a
      Uma Shankar authored
      EXT2 GC MAX registers are introduced from Gen10+ to
      program values from 3.0 to 7.0. Enabled the same, but
      currently limiting it to 1.0 as userspace ABI is limited
      at that currently.
      
      v2: Updated the 1.0 programming and aligned as per GLK, also added
      GLK along with GEN10+ check, as per Ville's feedback.

      drm/i915: Fix GCMAX color register programming · 61eae851
      Uma Shankar authored
      GC MAX register is used to program values from 1.0 to
      less than 3.0. A different register was used instead of
      the intended one. Fixed the same.
      
      Currently limiting it to 1.0 due to ABI limitations.
      
      v2: Updated the 1.0 programming and aligned as per GLK, based
      on Ville's feedback.

      drm/i915: fix i9xx irq enable/disable · e15be429
      Daniele Ceraolo Spurio authored
      Those functions are used on gen4 as well and gen4 does have a non-RCS
      engine, so remove the BUG_ON and flip back the logic to what it was
      before the ENGINE_READ/WRITE update
      
      v2: update the posting read as well (Chris, Ville).

      drm/i915: move the edram detection out of uncore init · f6ac993f
      Daniele Ceraolo Spurio authored
      edram is not part of uncore and there is no requirement for the
      detection to be done before we initialize the uncore functions. The
      first check on HAS_EDRAM is in the ggtt_init path, so move it to
      i915_driver_init_hw, where other dram-related detection happens.
      
      While at it, save the size in MB instead of the capabilities because the
      size is the only thing we look at outside of the init function.
