[PATCH v6 0/7] drm/i915: Convert fbdev to DRM client

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



Convert i915's fbdev code to struct drm_client. Replaces the current
ad-hoc integration. The conversion includes a number of cleanups. The
patchset also enables unloading of driver modules with in-kernel DRM
clients; a feature required by i915.

As with the other drivers' fbdev emulation, fbdev in i915 is now
an in-kernel DRM client that runs after the DRM device has been
registered. This allows to remove the asynchronous initialization.

i915 is the last driver with an fbdev emulation that is not build
upon struct drm_client. Once reviewed, the patches would ideally go
into drm-misc-next, so that the old fbdev helper code can be removed.
We can also attempt to add additional in-kernel clients. A DRM-based
dmesg log or a bootsplash are commonly mentioned. DRM can then switch
easily among the existing clients if/when required.

v6:
	* reorder patches to fix build (Jouni)
	* remove unnecessary handling of non-atomic commits (Jouni, Ville)
	* return errors from callbacks (Jouni)
	* various minor fixes
v5:
	* style fixes (checkpatch)
v4:
	<no changes>
v3:
	* support module unloading (Jani, CI bot)
	* as before, silently ignore devices without displays (CI  bot)
v2:
	* fix error handling (Jani)
	* fix non-fbdev builds
	* various minor fixes and cleanups
