You need that anyway for doing the ioctls (if you don't hand-roll the restarting yourself). Also our userspace has gone over to just outright copying the driver headers. Not the generic headers, but for the rendering side of gpus, which is the topic here, there's really not much generic stuff. > Jianxin, are you fixing it? So fix is either to depend upon libdrm for building, or have copies of the headers included in the package for the i915/amdgpu/radeon headers (drm/drm.h probably not so good idea).
