Hey Noralf, all,
I've been digging for a bit on the regression that this patch has
tripped on the HiKey board as reported here: https://lkml.org/lkml/2018/8/16/81
The first issue was that the kirin driver was setting mode_config.max_width/height = 2048, which was causing errors as the the requested resolution was 1920x2160 (due to surfaceflinger requesting y*2 for page flipping).
Hey Noralf, Sorry, I know your probably sick of me. But I just wanted to circle around on this little bit. So part of the issue I found earlier, was that I'm running w/ CONFIG_DRM_FBDEV_OVERALLOC=200, to support Surfaceflinger's request for page flipping.
Possibly slightly out of topic, but we're in 2018, is there any plan to make SurfaceFlinger move away from FBDEV ?
Yes. That is actually work-in-progress for both HiKey and HiKey960, switching to use the drm_hwcomposer once we can get upstream project into a sane state.
thanks -john
