- * Set the next domain for the specified object. This

- *
- * 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.
- *

- *
- *	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

+ * 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
+ *
