Merge branch 'for-airlied' of git://people.freedesktop.org/~danvet/drm-intel into drm-next 

Daniel writes:

" First -next pull for 3.7. Highlights:
- hsw hdmi improvements (Paulo)
- ips/rps locking rework and cleanups
- rc6 on ilk by default again
- hw context&dp&dpff support for hsw (Ben)
- GET_PARAM_HAS_SEMAPHORES (Chris)
- gen6+ pipe_control improvements (Chris)
- set_cacheing ioctl and assorted support code (Chris)
- cleanups around the busy/idle/pm code (Chris&me)
- flushing_list removal, hopefully for good (Chris)
- read_reg ioctl (Ben)
- support the ns2501 dvo (Thomas Richter)
- avoid the costly gen6+ "missed IRQ" workaround where we don't need a
  race-free seqno readback (Chris)
- various bits&pieces, mostly early patches from the modeset rework branch"

* Set the next domain for the specified object. This
* may not actually perform the necessary flushing/invaliding though,
* as that may want to be batched with other set_domain operations
*
* This is (we hope) the only really tricky part of gem. The goal
* is fairly simple -- track which caches hold bits of the object
* and make sure they remain coherent. A few concrete examples may
* help to explain how it works. For shorthand, we use the notation
* (read_domains, write_domain), e.g. (CPU, CPU) to indicate the
* a pair of read and write domain masks.
*
* Case 1: the batch buffer
*
* 1. Allocated
* 2. Written by CPU
* 3. Mapped to GTT
* 4. Read by GPU
* 5. Unmapped from GTT
* 6. Freed
*
* Let's take these a step at a time
*
* 1. Allocated
* Pages allocated from the kernel may still have
* cache contents, so we set them to (CPU, CPU) always.
* 2. Written by CPU (using pwrite)
* The pwrite function calls set_domain (CPU, CPU) and
* this function does nothing (as nothing changes)
* 3. Mapped by GTT
* This function asserts that the object is not
* currently in any GPU-based read or write domains
* 4. Read by GPU
* i915_gem_execbuffer calls set_domain (COMMAND, 0).
* As write_domain is zero, this function adds in the
* current read domains (CPU+COMMAND, 0).
* flush_domains is set to CPU.
* invalidate_domains is set to COMMAND
* clflush is run to get data out of the CPU caches
* then i915_dev_set_domain calls i915_gem_flush to
* emit an MI_FLUSH and drm_agp_chipset_flush
* 5. Unmapped from GTT
* i915_gem_object_unbind calls set_domain (CPU, CPU)
* flush_domains and invalidate_domains end up both zero
* so no flushing/invalidating happens
* 6. Freed
* yay, done
*
* Case 2: The shared render buffer
*
* 1. Allocated
* 2. Mapped to GTT
* 3. Read/written by GPU
* 4. set_domain to (CPU,CPU)
* 5. Read/written by CPU
* 6. Read/written by GPU
*
* 1. Allocated
* Same as last example, (CPU, CPU)
* 2. Mapped to GTT
* Nothing changes (assertions find that it is not in the GPU)
* 3. Read/written by GPU
* execbuffer calls set_domain (RENDER, RENDER)
* flush_domains gets CPU
* invalidate_domains gets GPU
* clflush (obj)
* MI_FLUSH and drm_agp_chipset_flush
* 4. set_domain (CPU, CPU)
* flush_domains gets GPU
* invalidate_domains gets CPU
* wait_rendering (obj) to make sure all drawing is complete.
* This will include an MI_FLUSH to get the data from GPU
* to memory
* clflush (obj) to invalidate the CPU cache
* Another MI_FLUSH in i915_gem_flush (eliminate this somehow?)
* 5. Read/written by CPU
* cache lines are loaded and dirtied
* 6. Read written by GPU
* Same as last GPU access
*
* Case 3: The constant buffer
*
* 1. Allocated
* 2. Written by CPU
* 3. Read by GPU
* 4. Updated (written) by CPU again
* 5. Read by GPU
*
* 1. Allocated
* (CPU, CPU)
* 2. Written by CPU
* (CPU, CPU)
* 3. Read by GPU
* (CPU+RENDER, 0)
* flush_domains = CPU
* invalidate_domains = RENDER

* drm_agp_chipset_flush
* 4. Updated (written) by CPU again
* (CPU, CPU)
* flush_domains = 0 (no previous write domain)
* invalidate_domains = 0 (no new read domains)
