07:27 <mszyprow^> memeka: ping

07:27 <memeka> mszyprow^: hi

07:28 <mszyprow^> memeka: where is the sd card image for reproducing mixer page fault? :)

07:28 <memeka> sorry i got myself busy with the wife leaving for a few days and did not manage to upload the image

07:28 <mszyprow^> memeka: okay, I also wasn't at the office yesterday

07:28 <memeka> plus, i was trying to get to the root cause and establish a simple program that crashes the DRM

07:28 <memeka> instead of "run kodi" :)

07:29 <memeka> so now i am trying to make MPV crash it, but i have to make it run gscaler first :))

07:29 <memeka> mszyprow^: but I have figured out something (after updating kodi too)

07:30 <memeka> with latest kodi, they assign specific planes for GUI and VIDEO

07:30 <memeka> GUI = overlay, VIDEO = primary

07:30 <memeka> as in, they create FB for each plane

07:30 <memeka> I think before there was only one FB

07:31 <memeka> and they were switching planes (somehow)

07:31 <memeka> so i think the DRM crash was happening because of this ...

07:31 <memeka> point in case: if i manually assign both GUI and VIDEO same plane => crash

07:32 <memeka> but now, i have another problem: isolating planes completely => i get only a black screen that can be fixed by reboot

07:32 <memeka> although stuff works (i can see kodi responds to my keypresses correctly)

07:33 <memeka> it's like the DRM and/or GBM drivers are not doing a flip or something

07:33 <memeka> or the FB gets lost

07:33 <memeka> dunno it's weird!

07:37 <memeka> mszyprow^: oh yeah! >> if i assign just GUI (egl gbm) to OVERLAY plane (GRAPHICS1) => the image "trembles" and after few seconds there's kernel crash!

07:38 <memeka> no video playing on PRIMARY plane ... just having EGL content on GRAPHICS1 ...

07:41 <memeka> mszyprow^: it doesn't ALWAYS crashes just by going into the menus ... but there's always a bit of ... small shaking of the image

07:41 <memeka> whereas on the other plane, it's rock solid

07:42 <memeka> looks like the rPi when it's undervolted :)

10:58 <memeka> kernel panic with MFC when stopping the encoder:

10:59 <memeka> https://www.irccloud.com/pastebin/3tridcWy/

10:59 <memeka> on kernel 4.18

11:03 <memeka> command: gst-launch-1.0 filesrc location=sintel_trailer-1080p.mp4 ! parsebin ! v4l2h264dec ! v4l2h264enc extra-controls="encode,frame_level_rate_control_enable=1,video_bitrate=10000000" ! h264parse ! matroskamux ! filesink location=transcoded.mkv

11:04 <memeka> then interrupt it with multiple CTRL-C
