drm: Reduce object size of DRM_DEV_ uses

2018-03-19T14:15:42+00:00

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.

drm: Reduce object size of DRM_ERROR and DRM_DEBUG uses

2018-03-16T07:41:57+00:00

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.

drm/print: Unconfuse kerneldoc

2017-12-15T10:13:39+00:00

It thinks we want to document the __printf(2,0) annotion. Not sure we
want to teach it about all possible gcc-only flags, hence why I opted
for the cheap trick of just moving it ahead of the kerneldoc.

This is only a problem for static inline functions, since for
non-inline function the kerneldoc is in the .c file, but the special
annotations are all in the header.

Cc'ing kernel-doc maintainers as fyi.

drm/doc: use preferred struct reference in kernel-doc

2016-12-30T12:34:59+00:00

sed -e 's/\( \* .*\)struct &\([_a-z]*\)/\1\&struct \2/' -i

Originally I wasnt a friend of this style because I thought a
line-break between the "&struct" and "foo" part would break it. But a
quick test shows that " * &struct \n * foo\n" works pefectly well with
current kernel-doc. So time to mass-apply these changes!
