Rework fbdev probing to support fbdev_probe in struct drm_driver and remove the old fb_probe callback. Provide an initializer macro for struct drm_driver that sets the callback according to the kernel configuration. Call drm_client_setup() to run the kernel's default client setup for DRM. Set fbdev_probe in struct drm_driver, so that the client setup can start the common fbdev client....

Hi! While trying to get CLUT support for the atmel_hlcdc driver, and specifically for the emulated fbdev interface, I received some push-back that my feeble in-driver attempts should be solved by the core. This is my attempt to do it right. Boris and Daniel, was this approximately what you had in mind? I have obviously not tested all of this with more than a compile, but the first patch is

As it turns out, on cards that actually have CRTCs on them we're already calling drm_kms_helper_poll_enable(drm_dev) from nouveau_display_resume() before we call it in nouveau_pmops_runtime_resume(). This leads us to accidentally trying to enable polling twice, which results in a potential deadlock between the RPM locks and drm_dev->mode_config.mutex if we end up trying to enable polling

...and also with Xorg + fbdev (startx -> xterm). The latter triggered a > warning in ttm_bo_vm_open that existed before, see > https://lkml.kernel.org/r/1464000533-13140-4-git-send-email-mstaudt at suse.de You can probably get rid of this one if you're refactoring even more. The generic fb_probe implementation (already merged) plus gem-shmem support for it (still in flight) from Noralf should be able to pull that off. That gives you the fb_mmap implementation, but with 100% generic code instead of a driver specific hack like Max did. > > Signed-off-by: Peter Wu <peter at lekenste...

When the fbcon object is initialized, but nouveau_fbcon_create is not called, we run into a NULL pointer access within nouveau_fbcon_create when unloading nouveau. The call to drm_fb_helper_funcs.fb_probe is deferred until there is a display for real since 4.14, that's why fbcon->helper.fb is still not set.
