/*
* GMEM is the small (ie. 256KiB for a200, 512KiB for a220, etc) tile buffer
* inside the GPU. All rendering happens to GMEM. Larger render targets
* are split into tiles that are small enough for the color (and depth and/or
* stencil, if enabled) buffers to fit within GMEM. Before rendering a tile,
* if there was not a clear invalidating the previous tile contents, we need
* to restore the previous tiles contents (system mem -> GMEM), and after all
* the draw calls, before moving to the next tile, we need to save the tile
* contents (GMEM -> system mem).
*
* The code in this file handles dealing with GMEM and tiling.
*
* The structure of the ringbuffer ends up being:
*
* +--<---<-- IB ---<---+---<---+---<---<---<--+
* | | | |
* v ^ ^ ^
* ------------------------------------------------------
* | clear/draw cmds | Tile0 | Tile1 | .... | TileN |
* ------------------------------------------------------
* ^
* |
* address submitted in issueibcmds
*
* Where the per-tile section handles scissor setup, mem2gmem restore (if
* needed), IB to draw cmds earlier in the ringbuffer, and then gmem2mem
* resolve.
