2018-03-19drm: Reduce object size of DRM_DEV_<LEVEL> usesJoe Perches1-9/+28
These macros are similar to the DRM_<LEVEL> 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_<LEVEL> * 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_<LEVEL> macros uses. Convert the DRM_DEV_<LEVEL> 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 <joe@perches.com> Signed-off-by: Daniel Vetter <daniel.vetter@ffwll.ch> Link: https://patchwork.freedesktop.org/patch/msgid/e5c164946e15375ac71b69b75f296efdf0b76e6d.1521233717.git.joe@perches.com
2018-03-16drm: Reduce object size of DRM_ERROR and DRM_DEBUG usesJoe Perches1-7/+21
drm_printk is used for both DRM_ERROR and DRM_DEBUG with unnecessary arguments that can be removed by creating separate functins. Create specific functions for these calls to reduce x86/64 defconfig size by ~20k. Modify the existing macros to use the specific calls. new: $ size -t drivers/gpu/drm/built-in.a | tail -1 1876562 44542 995 1922099 1d5433 (TOTALS) old: $ size -t drivers/gpu/drm/built-in.a | tail -1 1897565 44542 995 1943102 1da63e (TOTALS) Miscellanea: o intel_display requires a change to use the specific calls.

2017-10-30drm: Enable pr_debug() for drm_printerChris Wilson1-0/+2
pr_debug() is conditionally compiled and requires either dynamic-debugging to be enabled or for the code to opt-in using #define DEBUG. Since drm_print provides a central debugging facility using pr_debug(), make sure it will always produce output.
