[PATCH 09/10] drm/omapdrm: Set fbdev flags

Thomas Zimmermann tzimmermann at suse.de
Tue Jul 4 15:50:06 UTC 2023


Set fbdev default flags FBNFO_DEFAULT and mark the framebuffer with
FBINFO_VIRTFB. The framebuffer range is in DMA-able memory and should
be accessed with the CPU's regular memory ops.
