06:35 <sinxq> hi，how to driver mipi lcd on rk3399 debian?

06:36 <sinxq> [ 4.314915] rockchip-drm display-subsystem: bound ff900000.vop (ops 0xffffff8008a687f0) [ 4.316090] rockchip-drm display-subsystem: bound ff8f0000.vop (ops 0xffffff8008a687f0) [ 4.316897] rockchip-drm display-subsystem: failed to bind ff960000.mipi (ops 0xffffff8008a654e0): -517 [ 4.318401] rockchip-drm display-subsystem: master bind failed: -517

06:45 <beeble> sinxq: lot of things that can go wrong .

06:45 <beeble> you could take a look at a working dts and work back from there

06:45 <beeble> https://git.theobroma-systems.com/puma-linux.git/tree/arch/arm64/boot/dts/rockchip/rk3399-puma-mipidsi.dts for example

06:47 <beeble> also take a look at the branch commit log, there are some mipi patches that are not in the rockchip-linux release-4.4 tree

06:51 <sinxq> ok ,thanks beeble

06:58 <sinxq> hi,beeble,i have pathed this commit already before

07:03 <beeble> sinxq: sorry for not being of more help. a colleague has done this stuff and he is out of office today. i only know that it's working

07:36 <wzyy2> You could add some log in mipi bind funciton to see why it failed.

20:30 <oleavr> hi, I'm trying to do H.264 decoding and encoding on a Tinker Board, and keep seeing messages like: "rk-vcodec ff9a0000.vpu-service: can not find 28 buffer in list", and I've also seen quite a few kernel oops when trying to decode and encode in sequence. I'm using the GStreamer elements. are these known to be unstable?
