From 6bd488db80a4264669a7d612a1be1a91cb941cf6 Mon Sep 17 00:00:00 2001 From: Joe Perches Date: Sun, 25 Sep 2016 19:18:34 -0700 Subject: drm: Simplify drm_printk to reduce object size quite a bit Remove function name and special " *ERROR*" from argument list $ size drivers/gpu/drm/built-in.o* (x86-32 defconfig, most drm selected) text data bss dec hex filename 5635366 182579 14328 5832273 58fe51 drivers/gpu/drm/built-in.o.new 5779552 182579 14328 5976459 5b318b drivers/gpu/drm/built-in.o.old Using "%ps", __builtin_return_address(0) is the same as "%s", __func__ except for static inlines, but it's more or less the same output. Miscellanea: o Convert args... to ##__VA_ARGS__ o The equivalent DRM_DEV_ macros are rarely used and not worth conversion Reviewed-by: Chris Wilson Signed-off-by: Joe Perches Signed-off-by: Sean Paul Link: http://patchwork.freedesktop.org/patch/msgid/01f976d5ab93c985756fc1b2e83656fb0a2a28c8.1474856262.git.joe@perches.com --- include/drm/drmP.h | 30 ++++++++++++++---------------- 1 file changed, 14 insertions(+), 16 deletions(-) (limited to 'include/drm') diff --git a/include/drm/drmP.h b/include/drm/drmP.h index 289207f12adb..0e99669159c1 100644 --- a/include/drm/drmP.h +++ b/include/drm/drmP.h @@ -141,9 +141,8 @@ void drm_dev_printk(const struct device *dev, const char *level, unsigned int category, const char *function_name, const char *prefix, const char *format, ...); -extern __printf(5, 6) +extern __printf(3, 4) void drm_printk(const char *level, unsigned int category, - const char *function_name, const char *prefix, const char *format, ...); /***********************************************************************/ @@ -199,8 +198,7 @@ void drm_printk(const char *level, unsigned int category, drm_dev_printk(dev, KERN_ERR, DRM_UT_NONE, __func__, " *ERROR*",\ fmt, ##__VA_ARGS__) #define DRM_ERROR(fmt, ...) \ - drm_printk(KERN_ERR, DRM_UT_NONE, __func__, " *ERROR*", fmt, \ - ##__VA_ARGS__) + drm_printk(KERN_ERR, DRM_UT_NONE, fmt, ##__VA_ARGS__) /** * Rate limited error output.
