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 --- 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 c2fe2cf..1f53cc2 100644 --- a/include/drm/drmP.h +++ b/include/drm/drmP.h @@ -162,6 +162,26 @@ 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. * @@ -187,12 +207,6 @@ 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. *
