And we use it for faster copies on those GPUs, so it makes sense you'd be getting funny rectangles. You can disable it with nouveau.config=PCRYPT=0 which should cause it to use M2MF instead. It's *highly* surprising that you'd be getting that sort of issue though... no clue why that would happen. A few boards are missing PCRYPT, but in that case, it *never* works (including logging similar mmio faults on boot). Perhaps something messed up in the VBIOS init tables? BTW, in newer kernels, this will become PCIPHER instead of PCRYPT (for the nouveau.config line above).</pre> </div> <hr> You are receiving this mail because: <ul> <li>You are the assignee for the bug.</li> </ul> </body> </html>
