From db87086492581c87f768b7d17d01308153ecffc1 Mon Sep 17 00:00:00 2001 From: Joe Perches Date: Fri, 16 Mar 2018 13:56:27 -0700 Subject: drm: Reduce object size of DRM_DEV_ uses These macros are similar to the DRM_ with the addition of a struct device * to the arguments. Convert the single drm_dev_printk function into 2 separate functions. drm_dev_printk with a KERN_ * for generic use and drm_dev_dbg for conditional masked use. Remove the __func__ argument and use __builtin_return_address(0) to be similar to the DRM_ macros uses. Convert the DRM_DEV_ macros to remove now unnecessary arguments and use a consistent style. These macros are rarely used in the generic gpu/drm code so the code size does not change much for a defconfig, but when more drivers are enabled, there is ~4k savings. Many of these macros have no existing use at all. $ size -t drivers/gpu/drm/built-in.a | tail -1 1877530 44651 995 1923176 1d5868 (TOTALS) $ size -t drivers/gpu/drm/built-in.a | tail -1 1877527 44651 995 1923173 1d5865 (TOTALS) $ size -t drivers/gpu/drm/built-in.a | tail -1 17166750 2689238 108352 19964340 130a1b4 (TOTALS) $ size -t drivers/gpu/drm/built-in.a | tail -1 17168888 2691734 108352 19968974 130b3ce (TOTALS) Signed-off-by: Joe Perches Signed-off-by: Daniel Vetter Link: https://patchwork.freedesktop.org/patch/msgid/e5c164946e15375ac71b69b75f296efdf0b76e6d.1521233717.git.joe@perches.com --- drivers/gpu/drm/drm_print.c | 37 ++++++++++++++++++++++++++++--------- 1 file changed, 28 insertions(+), 9 deletions(-) (limited to 'drivers/gpu/drm') diff --git a/drivers/gpu/drm/drm_print.c b/drivers/gpu/drm/drm_print.c index 79abf6d5b4db..b25f98f33f6c 100644 --- a/drivers/gpu/drm/drm_print.c +++ b/drivers/gpu/drm/drm_print.c @@ -63,16 +63,34 @@ void drm_printf(struct drm_printer *p, const char *f, ...) } EXPORT_SYMBOL(drm_printf); -#define DRM_PRINTK_FMT "[" DRM_NAME ":%s]%s %pV" - void drm_dev_printk(const struct device *dev, const char *level, - unsigned int category, const char *function_name, - const char *prefix, const char *format, ...) + const char *format, ...) +{ + struct va_format vaf; + va_list args; + + va_start(args, format); + vaf.fmt = format; + vaf.va = &args; + + if (dev) + dev_printk(level, dev, "[" DRM_NAME ":%ps] %pV", + __builtin_return_address(0), &vaf); + else + printk("%s" "[" DRM_NAME ":%ps] %pV", + level, __builtin_return_address(0), &vaf); + + va_end(args); +} +EXPORT_SYMBOL(drm_dev_printk); + +void drm_dev_dbg(const struct device *dev, unsigned int category, + const char *format, ...) { struct va_format vaf; va_list args; - if (category != DRM_UT_NONE && !(drm_debug & category)) + if (!(drm_debug & category)) return; va_start(args, format); @@ -80,14 +98,15 @@ void drm_dev_printk(const struct device *dev, const char *level, vaf.va = &args; if (dev) - dev_printk(level, dev, DRM_PRINTK_FMT, function_name, prefix, - &vaf); + dev_printk(KERN_DEBUG, dev, "[" DRM_NAME ":%ps] %pV", + __builtin_return_address(0), &vaf); else - printk("%s" DRM_PRINTK_FMT, level, function_name, prefix, &vaf); + printk(KERN_DEBUG "[" DRM_NAME ":%ps] %pV", + __builtin_return_address(0), &vaf); va_end(args); } -EXPORT_SYMBOL(drm_dev_printk); +EXPORT_SYMBOL(drm_dev_dbg); void drm_dbg(unsigned int category, const char *format, ...) { -- cgit v1.2.3
