The issue is that that buffer is larger than the pci bar window into vram. The patch forces a scratch copy for all uploads. It would also probably be good to fix the kernel to check the offset in radeon_mode_dumb_mmap() if the domain is vram to see if it's larger than the pci window and return an error if so.</pre> </div> <hr> You are receiving this mail because: <ul> <li>You are the assignee for the bug.</li> </ul> </body> </html>
