Hi All,
I have a drm device on the platform bus, similar to the exynos driver. right now libdrm (at least the tests included in libdrm) refuses to open the device because i915, nouveau, radeon and vmwgfx is all they know about. Looking at the libdrm code it is not obvious how to fix this (except for adding "exynos", "mydevice", "myotherdevice" to the module table which seems awkward and not very futureproof). Any hints or thoughts how to proceed here?
Thanks Sascha

libdrm tests aren't really used that much, and it might be easier to just not care.
people just hack on them for their platforms and sometimes someone pushes one in.
You more likely want specific tests for your platform like intel-gpu-tools.
Dave.
Thanks Sascha

Ok, I can keep a local hack. What are your plans for the xf86-modesetting driver? It works nicely after I commented out some pci specific things and replaced drmOpen(NULL, BusID) with open("/dev/dri/card0", O_RDWR). Do you plan to continue on the driver and would accept patches for it?

might be why I added busid to the usb, my memory of why is hazy.
you should have been able to specify /dev/dri/card0 in the xorg.conf Option "kmsdev"
and yes I'll continue working on it, I have to hook it in as a linux fallback driver in the X server.
