I've rebased following patch series on current (todays) drm-tip: <a href="https://patchwork.freedesktop.org/series/28536">https://patchwork.freedesktop.org/series/28536</a> You can find the branch here: (I applied the patches with std patch, so I lost author information, I added the original author with the signed-off tag, not sure if this is the right thing to do, it's only for discussion anyway) <a href="https://github.com/a1rwulf/drm-tip/commits/yuv420">https://github.com/a1rwulf/drm-tip/commits/yuv420</a> It didn't work out and my system never switched to 4:2:0 until I tried this commit: <a href="https://github.com/a1rwulf/drm-tip/commit/45998e4d79aa20a31594143a3a053279fa52ab87">https://github.com/a1rwulf/drm-tip/commit/45998e4d79aa20a31594143a3a053279fa52ab87</a> According to my dmesg output something seems wrong, though (yuv420_dmesg.log). But this fixes the blackscreen flickering. I'd really like to see progress with this yuv 4:2:0 mode as it seems to fix a big issue for many Intel NUC users that want to use it as a HTPC and have a GUI running in 4k@60.</pre> </div> <hr> You are receiving this mail because: <ul> <li>You are the assignee for the bug.</li> <li>You are the QA Contact for the bug.</li> <li>You are on the CC list for the bug.</li> </ul> </body> </html>
