Custom HDMI timings hints

I just got a copy of the dev branch armbian comipled (2017-04-10).  I'm here with the grand goal of getting libsurvive running with the HTC Vive on the Orange Pi.  In order to do this, I need to coax the OrangePi to output to the vive.

I was skeptical at first, but it appears you guys support 4k@30, so it should be okay on the pixel-clock front. The vive is 2160x1200@90Hz.  You can't underclock it.  Just won't go then.  It's sadly the only mode the thing supports.

I've seen shreds and bits here and there of information about how to do this, but, it seems that most of it is out-of-date for the "dev" branch.  Any hints on how I can get the OrangePi to output as per the following modeline?

Modeline "Mode 0" 297.00 2160 2200 2220 2266 1200 1228 1230 1464 -hsync -vsync

have you looked at h3disp? Without parms it gives you the ones that are available. Your 4kp30 and 4kp25 modes are in there. You have to reboot after running the command as root to get it's affect. It writes to the /boot script and makes a backup in /boot in case you want to go back.

If you are talking about mainline kernel, video driver is in making. In any case, use Armbian forum, development section. First read this: https://forum.armbian.com/index. ... ments#comment-19367

Just FYI for anyone looking here still, Mainline is pretty much good to go! Armbian FTW!

A small update on this ... 4.14.y has DRM video driver, while we won't port it to 4.16.y due to way too much work ... and then its back again in 4.17.y + Simplefb video driver with simple functionality will be present in 4.16.y
