But more importantly, this will change the "unique" string (see drm_dev_set_unique). Sorry I did not get your comment about updating drm_dev_init/drm_dev_alloc documentation for this change. Do you see any issue if this "unique string " is changed The topic around it rather convoluted and messy, so please check this change doesn't cause subtle regressions. There's a doc hunk in drm_ioctl.c to begin with, plus userspace such as IGT [1] might rely on the current behaviour. HTH Emil [1] https://cgit.freedesktop.org/drm/igt-gpu-tools/ I did run vgem test from IGT to check for regression , do you suspect regression in other tests ?
