Part Number: DRA746
Tool/software: Linux
Dear Team,
We use custom h/w and software based on DRA746 and SDK 3.02.00.03.
I see following device node related to registered drm device and weston seems to be using card0 from the below log. However I would like to understand which device is registered as drm device with card1 and renderD129?
Is card1 is also being used? If yes then who creates it and how it is being used? What is the purpose of it?
#ls -l /dev/dri/
crw------- 1 root root 226, 0 Jan 1 00:00 card0 (omapdrm device)
crw------- 1 root root 226, 1 Jan 1 00:00 card1 (?)
crw------- 1 root root 226, 64 Jan 1 00:00 controlD64 (control node for card0)
crw------- 1 root root 226, 128 Jan 1 00:00 renderD128 (render node for card 0, which I think is PVR)
crw------- 1 root root 226, 129 Jan 1 00:00 renderD129 (?)
# cat /tmp/weston.log | grep card
[00:00:07.399] using /dev/dri/card0

Thanks & Regards,
