Hey On my i965/SNB system I profiled some games in WINE and saw that some unpack_* functions in src/mesa/main/format_unpack.c show up very highly.
In Day of Defeat: Source and Counter Strike: Source, the _mesa_unpack_uint_z_row function was 10~30%. In Starcraft II, the unpack_ARGB8888 function was 66%! I imagine we could optimize them by checking the value of 'n' and unrolling the loops if it's large enough, but I suspect the thing to do is figure out why they're being called so much to begin with and fix that. Any ideas? I'm also curious, in the case of unpack_ARGB8888 why does the (texture data?) have to be converted from byte integers to floats to begin with? Can't we use the integer data directly, or is this an inefficiency of WINE? Thanks, Matt _______________________________________________ mesa-dev mailing list mesa-dev@lists.freedesktop.org http://lists.freedesktop.org/mailman/listinfo/mesa-dev
