+ *
+ * 0 - Everything had to fit into the GTT. Both parties of a memcpy had to
+ * aligned and suitable for fencing, and still fit into the available
+ * mappable space left by the pinned display objects. A classic problem
+ * we called the page-fault-of-doom where we would ping-pong between
+ * two objects that could not fit inside the GTT and so the memcpy
+ * would page one object in at the expense of the other between every
+ * single byte.
+ *
+ * 1 - Objects can be any size, and have any compatible fencing (X Y, or none
+ * as set via i915_gem_set_tiling() [DRM_I915_GEM_SET_TILING]). If the
+ * object is too large for the available space (or simply too large
+ * for the mappable aperture!), a view is created instead and faulted
+ * into userspace. (This view is aligned and sized appropriately for
+ * fenced access.)
+ *
+ * Restrictions:
+ *
+ * * snoopable objects cannot be accessed via the GTT. It can cause machine
+ * hangs on some architectures, corruption on others. An attempt to service
+ * a GTT page fault from a snoopable object will generate a SIGBUS.
+ *
+ * * the object must be able to fit into RAM (physical memory, though no
+ * limited to the mappable aperture).
+ *
+ *
+ * Caveats:
+ *
+ * * a new GTT page fault will synchronize rendering from the GPU and flush
+ * all data to system memory. Subsequent access will not be synchronized.
+ *
+ * * all mappings are revoked on runtime device suspend.
+ *
+ * * there are only 8, 16 or 32 fence registers to share between all users
+ * (older machines require fence register for display and blitter access
+ * as well). Contention of the fence registers will cause the previous users
+ * to be unmapped and any new access will generate new page faults.
+ *
+ * * running out of memory while servicing a fault may generate a SIGBUS,

- * | B | C |
- * - enable pipe A.
- * - pipe B has a reduced DDB allocation that overlaps with the old pipe C

+ * The IC Resizer has a restriction that the output frame from the
+ * resizer must be 1024 or less in both width (pixels) and height
+ * (lines).
+ *
+ * The image converter attempts to split up a conversion when
+ * the desired output (converted) frame resolution exceeds the
+ * IC resizer limit of 1024 in either dimension.
+ *
+ * If either dimension of the output frame exceeds the limit, the
+ * dimension is split into 1, 2, or 4 equal stripes, for a maximum
+ * of 4*4 or 16 tiles. A conversion is then carried out for each
+ * tile (but taking care to pass the full frame stride length to
+ * the DMA channel's parameter memory!). IDMA double-buffering is used
+ * to convert each tile back-to-back when possible (see note below
+ * when double_buffering boolean is set).
+ *
+ * Note that the input frame must be split up into the same number
+ * of tiles as the output frame.
+ *
+ * FIXME: at this point there is no attempt to deal with visible seams
+ * at the tile boundaries when upscaling. The seams are caused by a reset
+ * of the bilinear upscale interpolation when starting a new tile. The
+ * seams are barely visible for small upscale factors, but become
+ * increasingly visible as the upscale factor gets larger, since more
+ * interpolated pixels get thrown out at the tile boundaries. A possilble
+ * fix might be to overlap tiles of different sizes, but this must be done
+ * while also maintaining the IDMAC dma buffer address alignment and 8x8 IRT
+ * alignment restrictions of each tile.
