From 742547b73d27e7bce2d0dd0f1b95692436f30950 Mon Sep 17 00:00:00 2001 From: Archit Taneja Date: Fri, 31 Jul 2015 16:21:42 +0530 Subject: drm/fb_helper: Create wrappers for blit, copyarea and fillrect funcs drm drivers that emulate fbdev populate their fb_fillrect, fb_copyarea and fb_imageblit fb_ops with the help of cfb_* or sys_* fbdev core helper functions. Create drm_fb_helper functions that wrap around these calls. This is part of an effort to prevent drm drivers from calling fbdev functions directly, in order to make fbdev emulation a top level drm option. v3: - Fixed kerneldoc errors v2: - Added kerneldocs - Follow the drm way of aligning of arguments in func definitions - Remove unnecessary checks for non NULL fb_info Signed-off-by: Archit Taneja Signed-off-by: Daniel Vetter --- include/drm/drm_fb_helper.h | 14 ++++++++++++++ 1 file changed, 14 insertions(+) (limited to 'include/drm/drm_fb_helper.h') diff --git a/include/drm/drm_fb_helper.h b/include/drm/drm_fb_helper.h index fc123685baf4..180290e62918 100644 --- a/include/drm/drm_fb_helper.h +++ b/include/drm/drm_fb_helper.h @@ -152,6 +152,20 @@ ssize_t drm_fb_helper_sys_read(struct fb_info *info, char __user *buf, ssize_t drm_fb_helper_sys_write(struct fb_info *info, const char __user *buf, size_t count, loff_t *ppos); +void drm_fb_helper_sys_fillrect(struct fb_info *info, + const struct fb_fillrect *rect); +void drm_fb_helper_sys_copyarea(struct fb_info *info, + const struct fb_copyarea *area); +void drm_fb_helper_sys_imageblit(struct fb_info *info, + const struct fb_image *image); + +void drm_fb_helper_cfb_fillrect(struct fb_info *info, + const struct fb_fillrect *rect); +void drm_fb_helper_cfb_copyarea(struct fb_info *info, + const struct fb_copyarea *area); +void drm_fb_helper_cfb_imageblit(struct fb_info *info, + const struct fb_image *image); + int drm_fb_helper_setcmap(struct fb_cmap *cmap, struct fb_info *info); int drm_fb_helper_hotplug_event(struct drm_fb_helper *fb_helper); -- cgit v1.2.3
