08:12 <krzk> Viciouss: the advantage is exactly that you will see which are disabled and they will get disabled to save power. Except this they should be in DT for complete description of HW.

08:27 <chewitt> krzk mszyprow I'm interested to know what happened to this patch series:

08:27 <chewitt> https://patchwork.kernel.org/project/linux-samsung-soc/cover/20190301122055.7135-1-a.hajda@samsung.com/

08:27 <chewitt> I'm not interested in Exynos5433

08:28 <chewitt> but 5422 would need to use similar pluming to get YUV output

08:29 <chewitt> is Andrzej Hajda still around?

08:32 <krzk> chewitt: the DTS parts are merged. The DRM, you would need to ask the Exynos DRM maintainer.

08:33 <krzk> Or just check in Git - did they land in kernel?

08:33 <chewitt> no, there was a v3 resend from Andrzej but I don't think it was merged

08:36 <mszyprow> chewitt: well, Inki (Exynos DRM maintainer) pointed some issues, which were not fixed due to lack of time, then Andrzej was (and still is...) busy with different things

08:37 <mszyprow> chewitt: Andrzej also tried tu get it working on 5422

08:37 <mszyprow> chewitt: but without a luck

08:37 <mszyprow> chewitt: there are some design differences between 5422 and 5433

08:38 <mszyprow> chewitt: and the main problem with 5422 is that there no working reference code

08:38 <chewitt> ahh, that won't help :)

08:38 <chewitt> the goal is (was) to get Kodi usable

08:39 <chewitt> I have been poking panfrost support, which is similarly not good

08:39 <chewitt> but I have kbase/blob working on 5.9

08:40 <chewitt> but Kodi has moved to GBM/V4L2 with DRMPRIME

08:41 <chewitt> "memeka" had a proof of concept for doing RGB > YUV conversion within ffmpeg

08:41 <mps> panfrost is better on 5.10-rc than previous ones, though not yet 'fantastic'

08:41 <chewitt> Kodi faults shortly after you start it

08:42 <chewitt> and I'm having trouble capturing anything useful about what the GPU is doing to feed panfrost devs clues

08:42 <mps> does kodi use Xorg or Wayland, or maybe something 'direct'

08:42 <chewitt> I'm told T628 has lots of errata :)

08:43 <chewitt> I work on LibreELEC which uses GBM

08:43 <chewitt> Kodi also supports Wayland and X11 but neither is needed

08:45 <mps> in previous kernel version I tweaked panfrost with setting frequencies in /sys/class/devfreq/ff9a0000.gpu/

08:47 <chewitt> it's common to see people force "performance" in power management with kbase

16:53 <Viciouss> krzk: it was less of a problem than I thought, it looks like the driver reads the state on boot and can see whether the regulator was on or off to begin with, therefor it didn't disable those that were already unused. I only had to find those that were freezing the system when unpowered and for the rest I could just wait for the shutdown messages and see which were missing
