This changes the fb name from "nouveaufb" to "nouveaudrmfb". Aside: I wonder whether the in_interrupt() check is good enough for the nouveau acceleration. Cargo-cult says drm_can_sleep() is needed, which isn't actually working if you pick a .config without PREEMPT. For the generic fbdev defio support we've gone with offloading everything to a worker. For the non-accel callbacks (set_par, blank and friends) checking for oops_in_progress is good enough to catch all the evil calling contexts. v2: Rebase Acked-by: Noralf Trønnes <noralf@tronnes.org> Reviewed-by: Alex Deucher <alexander.deucher@amd.com> Signed-off-by: Daniel Vetter <daniel.vetter@intel.com> Cc: Ben Skeggs <bskeggs@redhat.com> Cc: nouveau@lists.freedesktop.org Link: https://patchwork.freedesktop.org/patch/msgid/20190326132008.11781-14-daniel.vetter@ffwll.ch
