Hi Matthew, Trying the latest -next on the Jetson TK1 board (with two different DRM devices and display and render), I noticed that the GPU device probe always failed with error -ENOSPC. After investigating I figured out that this was due to the minor device allocation failing when a second DRM device is added. More precisely, when drm_minor_alloc() is called with DRM_MINOR_PRIMARY (0) as argument for a second time, the call to idr_alloc() (which has a requested range of 0..64) fails instead of returning 1 as expected. Note that the first call is successful. Reverting "reimplement IDR and IDA using the radix tree" on 20161213's next fixes the issue for me, suggesting a bug may have slipped in there. Not sure how this could be fixed, so reporting the issue for now in case it is not known yet. Cheers, Alex. _______________________________________________ dri-devel mailing list dri-devel@xxxxxxxxxxxxxxxxxxxxx https://lists.freedesktop.org/mailman/listinfo/dri-devel
