+/** @file drm_gem.c
+ *
+ * This file provides some of the base ioctls and library routines for
+ * the graphics memory manager implemented by each device driver.
+ *
+ * Because various devices have different requirements in terms of
+ * synchronization and migration strategies, implementing that is left up to
+ * the driver, and all that the general API provides should be generic --
+ * allocating objects, reading/writing data with the cpu, freeing objects.
+ * Even there, platform-dependent optimizations for reading/writing data with
+ * the CPU mean we'll likely hook those out to driver-specific calls. However,
+ * the DRI2 implementation wants to have at least allocate/mmap be generic.
+ *
+ * The goal was to have swap-backed object allocation managed through
+ * struct file. However, file descriptors as handles to a struct file have
+ * two major failings:
+ * - Process limits prevent more than 1024 or so being used at a time by
+ * default.
+ * - Inability to allocate high fds will aggravate the X Server's select()
+ * handling, and likely that of many GL client applications as well.
+ *
+ * This led to a plan of using our own integer IDs (called handles, following
+ * DRM terminology) to mimic fds, and implement the fd syscalls we need as
+ * ioctls. The objects themselves will still include the struct file so
+ * that we can transition to fds if the required kernel infrastructure shows
+ * up at a later date, and as our interface with shmfs for memory allocation.

+ * 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

+ * 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?)

+/** @file i915_gem_tiling.c
+ *
+ * Support for managing tiling state of buffer objects.
+ *
+ * The idea behind tiling is to increase cache hit rates by rearranging
+ * pixel data so that a group of pixel accesses are in the same cacheline.
+ * Performance improvement from doing this on the back/depth buffer are on
+ * the order of 30%.
+ *
+ * Intel architectures make this somewhat more complicated, though, by
+ * adjustments made to addressing of data when the memory is in interleaved
+ * mode (matched pairs of DIMMS) to improve memory bandwidth.
+ * For interleaved memory, the CPU sends every sequential 64 bytes
+ * to an alternate memory channel so it can get the bandwidth from both.
+ *
+ * The GPU also rearranges its accesses for increased bandwidth to interleaved
+ * memory, and it matches what the CPU does for non-tiled. However, when tiled
+ * it does it a little differently, since one walks addresses not just in the
+ * X direction but also Y. So, along with alternating channels when bit
+ * 6 of the address flips, it also alternates when other bits flip -- Bits 9
+ * (every 512 bytes, an X tile scanline) and 10 (every two X tile scanlines)
+ * are common to both the 915 and 965-class hardware.
+ *
+ * The CPU also sometimes XORs in higher bits as well, to improve
+ * bandwidth doing strided access like we do so frequently in graphics. This
+ * is called "Channel XOR Randomization" in the MCH documentation. The result
+ * is that the CPU is XORing in either bit 11 or bit 17 to bit 6 of its address
+ * decode.
+ *
+ * All of this bit 6 XORing has an effect on our memory management,
+ * as we need to make sure that the 3d driver can correctly address object
+ * contents.
+ *
+ * If we don't have interleaved memory, all tiling is safe and no swizzling is
+ * required.
+ *
+ * When bit 17 is XORed in, we simply refuse to tile at all. Bit
+ * 17 is not just a page offset, so as we page an objet out and back in,
+ * individual pages in it will have different bit 17 addresses, resulting in
+ * each 64 bytes being swapped with its neighbor!
+ *
+ * Otherwise, if interleaved, we have to tell the 3d driver what the address
+ * swizzling it needs to do is, since it's writing with the CPU to the pages
+ * (bit 6 and potentially bit 11 XORed in), and the GPU is reading from the
+ * pages (bit 6, 9, and 10 XORed in), resulting in a cumulative bit swizzling
+ * required by the CPU of XORing in bit 6, 9, 10, and potentially 11, in order
+ * to match what the GPU expects.
