Replaces the current ad-hoc integration. The conversion includes a number of cleanups. As with most other driver's fbdev emulation, fbdev in i915 is now just another DRM client that runs after the DRM device has been registered. This allows to remove the asynchronous initialization. I've long wanted to send out an update for this patchset. 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. v2: * fix error handling (Jani) * fix non-fbdev builds * various minor fixes and cleanups Thomas Zimmermann (4): drm/i915: Move fbdev functions drm/i915: Initialize fbdev DRM client with callback functions drm/i915: Implement fbdev client callbacks drm/i915: Implement fbdev emulation as in-kernel client drivers/gpu/drm/i915/display/intel_display.c | 1 - .../drm/i915/display/intel_display_driver.c | 19 -- drivers/gpu/drm/i915/display/intel_fbdev.c | 250 ++++++++++-------- drivers/gpu/drm/i915/display/intel_fbdev.h | 29 +- drivers/gpu/drm/i915/i915_driver.c | 24 +- 5 files changed, 139 insertions(+), 184 deletions(-) base-commit: f8d21cb17a99b75862196036bb4bb93ee9637b74
