So this patch fills out the set by providing both regular and once-only macros for each of the levels INFO, NOTICE, and WARNING, using a common underlying macro that does all the token-pasting. DRM_ERROR is unchanged, as it's not just a printk wrapper. v2: Fix whitespace, missing ## (Eric Engestrom) Signed-off-by: Dave Gordon Reviewed-by: Eric Engestrom Cc: dri-devel@lists.freedesktop.org --- include/drm/drmP.h | 26 ++++++++++++++++++++------ 1 file changed, 20 insertions(+), 6 deletions(-) diff --git a/include/drm/drmP.h b/include/drm/drmP.h index f8e87fd..734e4fb 100644 --- a/include/drm/drmP.h +++ b/include/drm/drmP.h @@ -163,6 +163,26 @@ void drm_err(const char *format, ...); /** \name Macros to make printk easier */ /*@{*/ +#define _DRM_PRINTK(once, level, fmt, ...) \ + do { \ + printk##once(KERN_##level "[" DRM_NAME "] " fmt, \ + ##__VA_ARGS__); \ + } while (0) + +#define DRM_INFO(fmt, ...) \ + _DRM_PRINTK(, INFO, fmt, ##__VA_ARGS__) +#define DRM_NOTE(fmt, ...) \ + _DRM_PRINTK(, NOTICE, fmt, ##__VA_ARGS__) +#define DRM_WARN(fmt, ...) \ + _DRM_PRINTK(, WARNING, fmt, ##__VA_ARGS__) + +#define DRM_INFO_ONCE(fmt, ...) \ + _DRM_PRINTK(_once, INFO, fmt, ##__VA_ARGS__) +#define DRM_NOTE_ONCE(fmt, ...) \ + _DRM_PRINTK(_once, NOTICE, fmt, ##__VA_ARGS__) +#define DRM_WARN_ONCE(fmt, ...) \ + _DRM_PRINTK(_once, WARNING, fmt, ##__VA_ARGS__) + /** * Error output. * @@ -188,12 +208,6 @@ void drm_err(const char *format, ...); drm_err(fmt, ##__VA_ARGS__); \ }) -#define DRM_INFO(fmt, ...) \ - printk(KERN_INFO "[" DRM_NAME "] " fmt, ##__VA_ARGS__) - -#define DRM_INFO_ONCE(fmt, ...) \ - printk_once(KERN_INFO "[" DRM_NAME "] " fmt, ##__VA_ARGS__) - /** * Debug output. *
