01:24 <naoki> Kwiboo: about u-boot for ROCK Pi S, still do you need Tested-by?

08:23 <qschulz> naoki: Tested-bys are always welcomed

12:22 <minute> why did the collabora rk3588 patchstack nuke any support for hdmi1 since 6.10?

12:30 <rtp> what are you calling hdmi1 ?

12:30 <rtp> hdmi should work on rk3588 iirc

12:40 <minute> rtp: second hdmi controller

12:42 <minute> hdmi@fdea0000

12:56 <sre> minute: the patches Cristian worked on never had support for the second hdmi controller. He is focussing on getting any graphical output working upstream before getting lost in details like audio, CEC, 8K, second controller, ...

12:59 <minute> sre: but it was working, and HDMI1 related bits were in here https://gitlab.collabora.com/hardware-enablement/rockchip-3588/linux/-/blob/rk3588-v6.9/drivers/gpu/drm/rockchip/dw_hdmi-rockchip.c?ref_type=heads#L85

12:59 <minute> sre: as you can see, in the 6.10 branch they're gone https://gitlab.collabora.com/hardware-enablement/rockchip-3588/linux/-/blob/rk3588-v6.10/drivers/gpu/drm/rockchip/dw_hdmi-rockchip.c?ref_type=heads#L57

13:04 <sre> and as you can see the driver went from 3000 loc to 900. As I said the idea is to strip down the unused/untested features to make review easy and get something upstream ASAP.

13:05 <minute> i see. then we'll need to do some forward-porting of the old version until that support comes back

13:11 <sre> If you need all the features in some non-mainline fork, you can also look into forward porting the original vendor driver. Panthor (the open source Mali GPU driver) was developed like that originally.

13:13 <minute> we only need the featureset that was in the 6.9 patchstack...

13:14 <sre> forward porting that should be easy
