From 73415b4ea5b5a257db6b5bd135b305cd945e63de Mon Sep 17 00:00:00 2001 From: Sam Ravnborg Date: Sun, 21 Jul 2019 16:06:10 +0200 Subject: [PATCH] drm/fb: remove unused function: drm_gem_fbdev_fb_create() MIME-Version: 1.0 Content-Type: text/plain; charset=utf8 Content-Transfer-Encoding: 8bit After migrating several drivers to the generic fbdev emulation there are no users left of drm_gem_fbdev_fb_create. Delete the function. Noticed that there was no callers while browsing around in the drm_fb* code. The code that referenced the function was removed by: commit 13aff184ed9f ("drm/qxl: remove dead qxl fbdev emulation code") The actual use was removed by: commit 26d4707d445d ("drm/qxl: use generic fbdev emulation") v2: - Updated changelog based on feedback from Noralf Signed-off-by: Sam Ravnborg Reviewed-by: Noralf Trønnes Cc: Gerd Hoffmann Cc: Daniel Vetter Link: https://patchwork.freedesktop.org/patch/msgid/20190721140610.GA20842@ravnborg.org --- drivers/gpu/drm/drm_gem_framebuffer_helper.c | 43 -------------------- include/drm/drm_gem_framebuffer_helper.h | 7 ---- 2 files changed, 50 deletions(-) diff --git a/drivers/gpu/drm/drm_gem_framebuffer_helper.c b/drivers/gpu/drm/drm_gem_framebuffer_helper.c index a6426c95b383..f61304054786 100644 --- a/drivers/gpu/drm/drm_gem_framebuffer_helper.c +++ b/drivers/gpu/drm/drm_gem_framebuffer_helper.c @@ -322,46 +322,3 @@ int drm_gem_fb_simple_display_pipe_prepare_fb(struct drm_simple_display_pipe *pi return drm_gem_fb_prepare_fb(&pipe->plane, plane_state); } EXPORT_SYMBOL(drm_gem_fb_simple_display_pipe_prepare_fb); - -/** - * drm_gem_fbdev_fb_create - Create a GEM backed &drm_framebuffer for fbdev - * emulation - * @dev: DRM device - * @sizes: fbdev size description - * @pitch_align: Optional pitch alignment - * @obj: GEM object backing the framebuffer - * @funcs: Optional vtable to be used for the new framebuffer object when the - * dirty callback is needed. - * - * This function creates a framebuffer from a &drm_fb_helper_surface_size - * description for use in the &drm_fb_helper_funcs.fb_probe callback. - * - * Returns: - * Pointer to a &drm_framebuffer on success or an error pointer on failure. - */ -struct drm_framebuffer * -drm_gem_fbdev_fb_create(struct drm_device *dev, - struct drm_fb_helper_surface_size *sizes, - unsigned int pitch_align, struct drm_gem_object *obj, - const struct drm_framebuffer_funcs *funcs) -{ - struct drm_mode_fb_cmd2 mode_cmd = { 0 }; - - mode_cmd.width = sizes->surface_width; - mode_cmd.height = sizes->surface_height; - mode_cmd.pitches[0] = sizes->surface_width * - DIV_ROUND_UP(sizes->surface_bpp, 8); - if (pitch_align) - mode_cmd.pitches[0] = roundup(mode_cmd.pitches[0], - pitch_align); - mode_cmd.pixel_format = drm_driver_legacy_fb_format(dev, sizes->surface_bpp, - sizes->surface_depth); - if (obj->size < mode_cmd.pitches[0] * mode_cmd.height) - return ERR_PTR(-EINVAL); - - if (!funcs) - funcs = &drm_gem_fb_funcs; - - return drm_gem_fb_alloc(dev, &mode_cmd, &obj, 1, funcs); -} -EXPORT_SYMBOL(drm_gem_fbdev_fb_create); diff --git a/include/drm/drm_gem_framebuffer_helper.h b/include/drm/drm_gem_framebuffer_helper.h index 7f307e834eef..d9f13fd25b0a 100644 --- a/include/drm/drm_gem_framebuffer_helper.h +++ b/include/drm/drm_gem_framebuffer_helper.h @@ -33,11 +33,4 @@ int drm_gem_fb_prepare_fb(struct drm_plane *plane, struct drm_plane_state *state); int drm_gem_fb_simple_display_pipe_prepare_fb(struct drm_simple_display_pipe *pipe, struct drm_plane_state *plane_state); - -struct drm_framebuffer * -drm_gem_fbdev_fb_create(struct drm_device *dev, - struct drm_fb_helper_surface_size *sizes, - unsigned int pitch_align, struct drm_gem_object *obj, - const struct drm_framebuffer_funcs *funcs); - #endif -- 2.30.2
