Revision 01b947afaa940327e7adf57070a4bf3d0bed9810 authored by Thomas Zimmermann on 05 July 2019, 07:31:00 UTC, committed by Gerd Hoffmann on 01 August 2019, 13:01:35 UTC 
drm/fb-helper: Instanciate shadow FB if configured in device's mode_config
 
Generic framebuffer emulation uses a shadow buffer for framebuffers with
dirty() function. If drivers want to use the shadow FB without such a
function, they can now set prefer_shadow or prefer_shadow_fbdev in their
mode_config structures. The former flag is exported to userspace, the
latter flag is fbdev-only.

v3:
	* only schedule dirty worker if fbdev uses shadow fb
	* test shadow fb settings with boolean operators
	* use bool for struct drm_mode_config.prefer_shadow_fbdev
	* fix documentation comments
