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
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 Signed-off-by: Thomas Zimmermann <tzimmermann@suse.de> Reviewed-by: Noralf Trønnes <noralf@tronnes.org> Tested-by: Noralf Trønnes <noralf@tronnes.org> Link: https://patchwork.freedesktop.org/patch/315834/ Signed-off-by: Gerd Hoffmann <kraxel@redhat.com>
