      drm/i915: Rename dev_priv->ring to dev_priv->render_ring. · d3301d86
      Eric Anholt 提交于
      With the advent of the BSD ring, be clear about which ring this is.
      The docs are pretty consistent with calling this the Render engine at
      this point.

      drm/i915: Move ringbuffer-related code to intel_ringbuffer.c. · 62fdfeaf
      Eric Anholt 提交于
      This is preparation for supporting multiple ringbuffers on Ironlake.
      The non-copy-and-paste changes are:
      - de-staticing functions
      - I915_GEM_GPU_DOMAINS moving to i915_drv.h to be used by both files.
      - i915_gem_add_request had only half its implementation
        copy-and-pasted out of the middle of it.

      drm/i915: Fail to load driver if KMS request without GEM · 79a78dd6
      Chris Wilson 提交于
      The i915's implementation of KMS requires GEM in order to manage the
      memory and execution domains of the framebuffer and associated
      resources. By the point at which we detect broken a BIOS and need to
      disable GEM, we have already registered ourselves as a KMS driver with
      several subsystems. Rather than introducing a fragile unwind and attempt
      to continue with UMS, spit out an error and unload the driver.
