04:55 <memeka> i saw the IPPv2 patches accepted in 4.18 .... does this mean that now exynos5422 DRM can accept NV12/NV21?

04:56 <memeka> up to 4.17, drm on exynos5x would show only yuv on the (single) plane

04:56 <memeka> also, can gscaler be used as a video drm plane?

07:15 <memeka> mszyprow: hello

07:15 <mszyprow> memeka: hi

07:16 <memeka> mszyprow: i saw the IPPv2 patches accepted in 4.18 .... does this mean that now exynos5422 DRM can accept NV12/NV21?

07:16 <memeka> 2:26 PM also, can gscaler be used as a video drm plane?

07:16 <memeka> 2:26 PM up to 4.17, drm on exynos5x would show only yuv on the (single) plane

07:16 <memeka> 2:57 PM → mszyprow joined ↔ aalm nipped out

07:16 <memeka> 4:45 PM <memeka>

07:16 <mszyprow> memeka: not yet, ippv2 is only mem2mem

07:17 <memeka> mszyprow: i saw there were some patches to add scaler to drm

07:17 <memeka> is that like another drm plane?

07:17 <memeka> also the patch said that gscaler is now correctly working in drm driver

07:17 <mszyprow> memeka: this is mem2mem only scaler

07:18 <mszyprow> memeka: gscaler is also working in mem2mem mode

07:18 <mszyprow> memeka: we did some research on gscaler in local path to display, but it will be first done for exynos5433

07:18 <memeka> mszyprow: isn't MFC -> GScaler -> output m2m ?

07:19 <memeka> oh no :( why not 5422 first? :D

07:19 <memeka> there are more 5422 boards out there :P

07:19 <mszyprow> memeka: 5433 is more important for us

07:19 <mszyprow> once it is done and we have some spare time, we will chekc 5422 again

07:19 <memeka> so this means, even in 4.18, 5422 drm supports only yuv?

07:20 <mszyprow> rgb

07:20 <memeka> no nv21/nv12 :(

07:21 <memeka> so drm prime still won't work :(

07:24 <mszyprow> memeka: we didn't manage to get it working on 5250 or 5422 yet

07:24 <mszyprow> in case of 5433 we had a bit more luck and better documentation

13:22 <memeka> mszyprow: back :D

13:22 <memeka> mszyprow: so the issue was (still) that 5422 drm doesn't accept nv12/nv21?

13:24 <mszyprow> memeka: the issue is that we still don't really know how to program hw registers to get working nv12 plane (despite the fact that hw docs says it should work)

13:25 <mszyprow> memeka: I need to go now

13:25 <memeka> mszyprow: np thanks
