This is a temporary export that allows to move the DRM I/O helpers for fbdev into drivers. Only fbdev-generic and i915 need them. Both will be updated to implement damage handling by themselves and the exported functions will be removed. v4: * update interfaces Signed-off-by: Thomas Zimmermann Reviewed-by: Sam Ravnborg --- drivers/gpu/drm/drm_fb_helper.c | 22 ++++++++++++++++++++++ include/drm/drm_fb_helper.h | 3 +++ 2 files changed, 25 insertions(+) diff --git a/drivers/gpu/drm/drm_fb_helper.c b/drivers/gpu/drm/drm_fb_helper.c index f0e9549b6bd7..cb03099fd2e3 100644 --- a/drivers/gpu/drm/drm_fb_helper.c +++ b/drivers/gpu/drm/drm_fb_helper.c @@ -670,6 +670,28 @@ static void drm_fb_helper_memory_range_to_clip(struct fb_info *info, off_t off, drm_rect_init(clip, x1, y1, x2 - x1, y2 - y1); } +/* Don't use in new code. */ +void drm_fb_helper_damage_range(struct fb_info *info, off_t off, size_t len) +{ + struct drm_fb_helper *fb_helper = info->par; + struct drm_rect damage_area; + + drm_fb_helper_memory_range_to_clip(info, off, len, &damage_area); + drm_fb_helper_damage(fb_helper, damage_area.x1, damage_area.y1, + drm_rect_width(&damage_area), + drm_rect_height(&damage_area)); +} +EXPORT_SYMBOL(drm_fb_helper_damage_range); + +/* Don't use in new code. */ +void drm_fb_helper_damage_area(struct fb_info *info, u32 x, u32 y, u32 width, u32 height) +{ + struct drm_fb_helper *fb_helper = info->par; + + drm_fb_helper_damage(fb_helper, x, y, width, height); +} +EXPORT_SYMBOL(drm_fb_helper_damage_area); + /** * drm_fb_helper_deferred_io() - fbdev deferred_io callback function * @info: fb_info struct pointer diff --git a/include/drm/drm_fb_helper.h b/include/drm/drm_fb_helper.h index 72032c354a30..7d5804882be7 100644 --- a/include/drm/drm_fb_helper.h +++ b/include/drm/drm_fb_helper.h @@ -253,6 +253,9 @@ void drm_fb_helper_fill_info(struct fb_info *info, struct drm_fb_helper *fb_helper, struct drm_fb_helper_surface_size *sizes); +void drm_fb_helper_damage_range(struct fb_info *info, off_t off, size_t len); +void drm_fb_helper_damage_area(struct fb_info *info, u32 x, u32 y, u32 width, u32 height); + void drm_fb_helper_deferred_io(struct fb_info *info, struct list_head *pagereflist); ssize_t drm_fb_helper_sys_read(struct fb_info *info, char __user *buf,
