From dfe63bb0ad9810db13aab0058caba97866e0a681 Mon Sep 17 00:00:00 2001 From: James Simmons Date: Thu, 23 Dec 2010 16:40:37 +0000 Subject: [PATCH] drm: Update fbdev fb_fix_screeninfo If you change the color depth via fbset or some other framebuffer aware userland application struct fb_fix_screeninfo is not updated to this new information. This patch fixes this issue. Also the function is changed to just pass in struct drm_framebuffer so in the future we could use more fields. I'm hoping some day fix->smem* could be set here :-) Signed-off-by: James Simmons Signed-off-by: Dave Airlie --- drivers/gpu/drm/drm_fb_helper.c | 41 +++++++++++++------------ drivers/gpu/drm/i915/intel_fb.c | 1 - drivers/gpu/drm/nouveau/nouveau_fbcon.c | 1 - drivers/gpu/drm/radeon/radeon_fb.c | 2 -- include/drm/drm_fb_helper.h | 3 -- 5 files changed, 21 insertions(+), 27 deletions(-) diff --git a/drivers/gpu/drm/drm_fb_helper.c b/drivers/gpu/drm/drm_fb_helper.c index 5c4f9b9ecdc0..0307d601f5e5 100644 --- a/drivers/gpu/drm/drm_fb_helper.c +++ b/drivers/gpu/drm/drm_fb_helper.c @@ -607,6 +607,25 @@ void drm_fb_helper_fini(struct drm_fb_helper *fb_helper) } EXPORT_SYMBOL(drm_fb_helper_fini); +void drm_fb_helper_fill_fix(struct fb_info *info, struct drm_framebuffer *fb) +{ + info->fix.type = FB_TYPE_PACKED_PIXELS; + info->fix.visual = fb->depth == 8 ?
