drm/gma500: Rewrite GTT page insert/remove without struct gtt_range struct gtt_range represents a GEM object and should not be used for GTT setup. Change psb_gtt_insert() and psb_gtt_remove() to receive all necessary parameters from their caller. This also eliminates possible failure from psb_gtt_insert(). There's one exception in psb_gtt_restore(), which requires an upcast from struct resource to struct gtt_range when restoring the GTT after hibernation. A possible solution would track the GEM objects that need restoration separately from the GTT resource. Rename the functions to psb_gtt_insert_pages() and psb_gtt_remove_pages() to reflect their similarity to MMU interfaces. v3: * restore the comments about locking rules (Patrik) Signed-off-by: Thomas Zimmermann <tzimmermann@suse.de> Acked-by: Patrik Jakobsson <patrik.r.jakobsson@gmail.com> Link: https://patchwork.freedesktop.org/patch/msgid/20211015084053.13708-10-tzimmermann@suse.de

gma500: gtt based hardware scrolling console Add support for GTT based scrolling. Instead of pushing bits around we simply use the GTT to change the mappings. This provides us with a very fast way to scroll the display providing we have enough memory to allocate on 4K line boundaries. In practice this seems to be the case except for very big displays such as HDMI, and the usual configurations are netbooks/tablets.
