2010-05-26drm/i915: add timeout to FBC disable waitsJesse Barnes
FBC disable on 965 can take long enough to trigger latency checks in the kernel so be sure to timeout after a reasonable period. Fixes https://bugzilla.kernel.org/show_bug.cgi?id=15015.

2010-05-26drm/i915: implement BSD ring buffer V2Zou Nan hai
The BSD (bit stream decoder) ring is used for accessing the BSD engine which decodes video bitstream for H.264 and VC1 on G45+. It is asynchronous with the render ring and has access to separate parts of the GPU from it, though the render cache is coherent between the two.

2010-05-26drm/i915: convert some gem structures to per-ring V2Zou Nan hai
The active list and request list move into the ringbuffer structure, so each can track its active objects in the order they are in that ring. The flushing list does not, as it doesn't matter which ring caused data to end up in the render cache. Objects gain a pointer to the ring they are active on (if any).

2010-05-26drm/i915: introduce intel_ring_buffer structure (V2)Zou Nan hai

2010-05-26drm/i915: Rename dev_priv->ring to dev_priv->render_ring.Eric Anholt
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.
2010-05-26drm/i915: Move ringbuffer-related code to intel_ringbuffer.c.Eric Anholt
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.
2010-05-26drm/i915: Fail to load driver if KMS request without GEMChris Wilson
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.

This patch is a combination of the previous two profile patches, but without the index bugs. It cleans up and fixes some issues with pm profile setup on r6xx chips. Some tables have different orderings for the power states, also, r600 only has 1 clock mode per power state. On desktop cards there are no battery modes, so the low and high power states are the same. For the low profile case, choose the lower clock mode.

2010-05-18drm/radeon/kms/pm: rework power managementAlex Deucher
- Separate dynpm and profile based power management methods. You can select the pm method by echoing the selected method ("dynpm" or "profile") to power_method in sysfs. - Expose basic 4 profile in profile method "default" - default clocks "auto" - select between low and high based on ac/dc state "low" - DC, low power mode "high" - AC, performance mode The current base profile is "default", but it should switched to "auto" once we've tested on more systems. Switching the state is a matter of echoing the requested profile to power_profile in sysfs. The lowest power states are selected automatically when dpms turns the monitors off in all states but default. - Remove dynamic fence-based reclocking for the moment. We can revisit this later once we have basic pm in. - Move pm init/fini to modesetting path. pm is tightly coupled with display state. Make sure display side is initialized before pm. - Add pm suspend/resume functions to make sure pm state is properly reinitialized on resume. - Remove dynpm module option. It's now selectable via sysfs. Signed-off-by: Alex Deucher <alexdeucher@gmail.com> Signed-off-by: Dave Airlie <airlied@redhat.com>
