Hi. I've pushed the intel-post-reloc branch with the following stuff:
1) Full backwards compatibility. 2) A new reloc type 1, which is applied _after_ all validations and with slightly different format. 3) If the buffer is idle, type 1 relocations are performed using the new kmap_atomic_prot_pfn if it's available. 4) If the buffer is busy, It's never mapped, and relocations are performed using a single dword 2D blit, and we never have to idle the buffer. This comes at a cost of an additional single MI_FLUSH after all blit-relocations have been performed. This could help avoid pre-validation relocation processing, race conditions due to the relocatee not being on the unfenced list when relocs are applied and unnecessary buffer idling. /Thomas ------------------------------------------------------------------------- This SF.net email is sponsored by: Microsoft Defy all challenges.
