- * 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
- * clflush (obj)
- * MI_FLUSH
- * 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)
- * 5. Read by GPU
- * (CPU+RENDER, 0)
- * flush_domains = CPU
- * invalidate_domains = RENDER
- * clflush (obj)
- * MI_FLUSH
