llvmpipe: tweak CMD_BLOCK_MAX and LP_SCENE_MAX_SIZE
We advertise a max texture/surfaces size of 8K x 8K but the old values for these limits didn't actually allow us to handle that surface size. For 8K x 8K we'll have 16384 bins. Each bin needs at least one cmd_block object which was 2192 bytes in size. Since 16384 * 2192 exceeded LP_SCENE_MAX_SIZE we'd silently fail in lp_scene_new_data_block() and not draw the complete scene. By reducing CMD_BLOCK_MAX to 29 we get nice 512-byte cmd_blocks. And by increasing LP_SCENE_MAX_SIZE to 9 MB we can allocate enough command blocks for 8K x 8K, plus a few regular data blocks. Fixes the (improved) piglit fbo-maxsize test. Note: This is a candidate for the stable branches. Reviewed-by: José Fonseca <[email protected]>
