But I did get the 14 LCD patches from that page. >> /dev/dri/* is also still missing - it is still my assumption that this >> should show up if all goes well - is this correct? > > Yeah you should get the unaccelerated dri available: > > $ find /dev/dri/ > /dev/dri/ > /dev/dri/card0 > /dev/dri/by-path > /dev/dri/by-path/platform-omapdrm.0-card > /dev/dri/by-path/platform-omapdrm.0-render > /dev/dri/renderD128 > > Not sure if and why we have some ordering problem with DSS if one of > the dts configured displays is not loaded. This is the output that I get now [1] - seems pretty similar to before I applied the TI LMU backlight patches. Config is here [2] LCD and HDMI do not seem to work yet - any clue what else I might have missed? (Also no /dev/dri entries) I'm also down with trying a slightly older tree (like 4.12) if that's known to work. > Also note that Linux next has the omap4 CEC driver merged that might > provide some fun too once you get things working. That would be fun indeed - but I assume it is unlikely to cause the current (perceived, at least on my end) breakage, right? [1] http://sprunge.us/Xaic [2] http://sprunge.us/AdES
