      drm/i915: Drop fb reference on load_detect_pipe failure path · 3e72be17
      Chris Wilson 提交于
      When intel_modeset_setup_plane_state() fails drop the local framebuffer
      reference before jumping to the error, otherwise we leak the framebuffer.

      intel/atomic: Stop updating legacy fb parameters · 7a1530d7
      Daniel Vetter 提交于
      Even fbc isn't using this stuff anymore, so time to remove it.
      
      Cleaning up one small piece of the atomic conversion cruft at the time
      ...
      
      Quick explanation on why the plane->fb assignment is ok to delete: The
      core code takes care of the refcounting and legacy ->fb pointer
      updating, but drivers are allowed to update it ahead of time. Most
      legacy modeset drivers did that as part of their set_config callback
      (since that's how the legacy/crtc helpers worked). In i915 we only
      need that to make the fbc code happy.
      
      v2: don't nuke the assignement of intel_crtc->config, I accidentally
      set CI ablaze :-) Spotted by Maarten. And better explain why nuking
      the ->fb assignement shouldn't set off alarm bells.

      drm/i915: Restore GT performance in headless mode with DMC loaded · b6876374
      Tvrtko Ursulin 提交于
      It seems that the DMC likes to transition between the DC states a lot when
      there are no connected displays (no active power domains) during command
      submission.
      
      This activity on DC states has a negative impact on the performance of the
      chip with huge latencies observed in the interrupt handlers and elsewhere.
      Simple tests like igt/gem_latency -n 0 are slowed down by a factor of
      eight.
      
      Work around it by introducing a new power domain named,
      POWER_DOMAIN_GT_IRQ, associtated with the "DC off" power well, which is
      held for the duration of command submission activity.
      
      CNL has the same problem which will be addressed as a follow-up. Doing
      that requires a fix for a DC6 context corruption problem in the CNL DMC
      firmware which is yet to be released.
      
      v2:
       * Add commit text as comment in i915_gem_mark_busy. (Chris Wilson)
       * Protect macro body with braces. (Jani Nikula)
      
      v3:
       * Add dedicated power domain for clarity. (Chris, Imre)
       * Commit message and comment text updates.
       * Apply to all big-core GEN9 parts apart for Skylake which is pending DMC
         firmware release.
      
      v4:
       * Power domain should be inner to device runtime pm. (Chris)
       * Simplify NEEDS_CSR_GT_PERF_WA macro. (Chris)
       * Handle async DMC loading by moving the GT_IRQ power domain logic into
         intel_runtime_pm. (Daniel, Chris)
       * Include small core GEN9 as well. (Imre)
      
      v5
       * Special handling for async DMC load is not needed since on failure the
         power domain reference is kept permanently taken. (Imre)
      
      v6:
       * Drop the NEEDS_CSR_GT_PERF_WA macro since all firmwares have now been
         deployed. (Imre, Chris)

      drm/i915/execlists: Cache ELSP register offset · 2fc7a06a
      Chris Wilson 提交于
      Currently on every submission, we recalculate the ELSP register offset
      for the engine, after chasing the pointers to find the iomem base. Since
      this is fixed for the lifetime of the driver, record the offset in the
      execlists struct.
      
      In practice the difference is negligible, it just happens to remove 27
      bytes of eyesore pointer dancing from next to the hottest instruction
      (which is itself due to stalling for a cache miss) in perf profiles of
      the execlists_submission_tasklet().
      
      v2: Trim off one more elsp local.

      drm/i915: Refactor common list iteration over GGTT vma · e2189dd0
      Chris Wilson 提交于
      In quite a few places, we have a list iteration over the vma on an
      object that only want to inspect GGTT vma. By construction, these are
      placed at the start of the list, so we have copied that knowledge into
      many callsites. Pull that knowledge back to i915_vma.h and provide a
      for_each_ggtt_vma() to tidy up the code.
      
      v2: Add a backreference from vma_create() to remind ourselves why we put
      ggtt vma at the head of the obj->vma_list (and ppgtt vma at the tail).
