From 6ba6d03e69125ef42a63e90d45e49c659ea3c34f Mon Sep 17 00:00:00 2001 From: Ville Syrjälä Date: Mon, 10 Jun 2013 11:15:10 +0300 Subject: drm: Print pretty names for pixel formats MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Rather than just printing the pixel format as a hex number, decode the fourcc into human readable form, and also decode the LE vs. BE flag. Keep printing the raw hex number too in case it contains non-printable characters. Some examples what the new drm_get_format_name() produces: DRM_FORMAT_XRGB8888: "XR24 little-endian (0x34325258)" DRM_FORMAT_YUYV: "YUYV little-endian (0x56595559)" DRM_FORMAT_RGB565|DRM_FORMAT_BIG_ENDIAN: "RG16 big-endian (0xb6314752)" Unprintable characters: "D??? big-endian (0xff7f0244)" v2: Fix patch author Signed-off-by: Ville Syrjälä Signed-off-by: Dave Airlie --- include/drm/drm_crtc.h | 1 + 1 file changed, 1 insertion(+) (limited to 'include/drm') diff --git a/include/drm/drm_crtc.h b/include/drm/drm_crtc.h index adb3f9b625f6..2cbbfd44c6df 100644 --- a/include/drm/drm_crtc.h +++ b/include/drm/drm_crtc.h @@ -1094,5 +1094,6 @@ extern int drm_format_num_planes(uint32_t format); extern int drm_format_plane_cpp(uint32_t format, int plane); extern int drm_format_horz_chroma_subsampling(uint32_t format); extern int drm_format_vert_chroma_subsampling(uint32_t format); +extern char *drm_get_format_name(uint32_t format); #endif /* __DRM_CRTC_H__ */ -- cgit 1.4.1
