Hi, I have a few questions about the R300 driver. I'm just wondering about a couple of things including the OPTIMIZE_ELTS code (r300_render.c) and R300_VAP_INPUT_ROUTE_0_0 and R300_VAP_INPUT_ROUTE_1_0.
I cleaned up the OPTIMIZE_ELTS code to reduce duplication, and I verified that both the optimized and non-optimized code works with Quake 3 Arena, however, I'm not exactly sure how this optimization works or what it's purpose is? The other question is regarding R300_VAP_INPUT_ROUTE_0_0 and R300_VAP_INPUT_ROUTE_1_0. The values for these registers are constructed in r300_emit.c with the functions t_vir0 and t_vir1, respectively, but I haven't figured these functions out yet. Lots of bitwise operations. I can go through this and figure it out, but if someone else already knows and can explain it that would certainly be helpful. :) I need to understand and extend these functions because r300_ioctl.c:r300EmitClearState writes hard-coded values to these registers, and this should be replaced with calls to (extended) t_vir0 and t_vir1. These probably need to be renamed, too. Thank you. ------------------------------------------------------------------------- This SF.net email is sponsored by DB2 Express Download DB2 Express C - the FREE version of DB2 express and take control of your XML.
