The problem described in this report happens because pinning to VRAM fails, because there isn't enough space in VRAM. The patch allows buffers to be pinned to GTT instead of VRAM for scanout. Another DC patch is probably needed to fix the garbled display described in <a href="show_bug.cgi?id=104275#c4">comment 4</a>. Maybe try the patch on top of the amd-staging-drm-next branch.</pre> </div> <hr> You are receiving this mail because: <ul> <li>You are the assignee for the bug.</li> </ul> </body> </html>
