We got a patch from the BSP team of the CPU vendor, which seems solved the problem. The patch replaces both RADEON_GPU_PAGE_SIZE in function r600_copy_blit() with PAGE_SIZE. (We use 16K PAGE_SIZE, and RADEON_GPU_PAGE_SIZE is 4K) Any idea? If it had copy problems, why bo moving test couldn't detect it? Also, after applied the patch, the bo moving test was still passed, curious. BTW, if the patch was correct, then it seems more suitable to be fixed in radeon_move_blit(): * The num_pages field of ttm_mem_reg need to be changed if moved between VRAM and GTT && PAGE != RADEON_GPU_PAGE_SIZE. * What is a drm_mm_node? Represent a block resides at VRAM/GTT/System Mem? --- Regards, Chen Jie _______________________________________________ xorg-driver-ati mailing list [email protected] http://lists.x.org/mailman/listinfo/xorg-driver-ati
