21:44 <luka177[m]> Hi! I am trying to bringup dual dsi video mode DSC panel on sm8250 device (Xiaomi Pad 6), and having some issues, while sometimes i can see corrupted DSC blocks for some reason moving across the screen to the top, usually i get just a white screen with 4 vertical lines of blue dots (likely each dot is a place where DSC block sjould start) the screen seems to be odly flickering or rather refrashing top to bottom after arond 20 seconds at

21:44 <luka177[m]> that screen on right half (dsi1 one) some cyan dots appear and move horizontaly back and forth. My source https://github.com/pipa-mainline/linux/commits/topic/pipa/panel

21:45 * luka177[m] uploaded an image: (8969KiB) < https://matrix.org/_matrix/media/v3/download/matrix.org/fZfMaEiTuwSCKIbvFuuvOhLa/20231109_224323.jpg >

21:45 <luka177[m]> Here is a photo i really hope you can see blu dots line and cyan dots on both sides of it

21:46 <Marijn[m]> luka177: unfortunately most of this is not imlemented or living on someone's local dev machine :)

21:46 <Marijn[m]> https://gitlab.freedesktop.org/drm/msm/-/issues/42

21:46 <Marijn[m]> https://gitlab.freedesktop.org/drm/msm/-/issues/36

21:47 <Marijn[m]> Oh. You are MollySophia, the person that reported these already, and seem to have found my patches :)

21:47 <Marijn[m]> Let's keep discussions on the drm/msm bugtracker I suppose? I'm still awaiting abhinav__ jessica_24 analyzing the devcoredump to point out where we need to go next

21:47 <luka177[m]> Marijn[m]: > <@marijns95:matrix.org> luka177: unfortunately most of this is not imlemented or living on someone's local dev machine :)... (full message at <https://matrix.org/_matrix/media/v3/download/matrix.org/rRLJuppDbKYRjIFGwwvWwdPc>)

21:48 <Marijn[m]> s/you are/you are using the source from/

21:48 <luka177[m]> once i got something similar tho more corrupted, and after i rebooted i never seen it again. The main issue for me is something causes inconsistency across reboots

21:50 <luka177[m]> Marijn[m]: https://github.com/edk2-porting/linux-next/tree/topic/pipa/panel is what they claim to use

21:53 <luka177[m]> both pclk0 and 1 seems to be same to what i have on downstream

21:56 <luka177[m]> once in +/- 20 boots i get this, i belive those bars to be corrupted DSC blocks, but not sure, fact that they are moving means some sync issue?

21:57 <Marijn[m]> luka177: there is so little implemented to make this possible currently that there's not really a point to look at occasional patterns that appear every ±20 boots, unfortunately

21:58 <luka177[m]> Marijn[m]: From what i have seen in issues on dual dsc dsi it is usually no data on dsi1 (right screen side) and some, partially corrupted data on right one, isnt it?

21:59 <Marijn[m]> Yeah, but that's with far more patches applied to the DSI host, and is only for CMDmode

22:20 <luka177[m]> <Marijn[m]> "Yeah, but that's with far more..." <- Hmm that is very strange as i did see actual image parts few times, on both halfs of the panel

22:21 <luka177[m]> (a slowmotion viseo, hard to see not corrupted blocks even when they appear without it)
