| H A D | drm_print.h | 84ec6728 Mon Sep 12 00:28:47 CDT 2022 Jim Cromie <jim.cromie@gmail.com> drm_print: wrap drm_*_dbg in dyndbg descriptor factory macro
For CONFIG_DRM_USE_DYNAMIC_DEBUG=y, wrap __drm_dbg() & __drm_dev_dbg()
in one of dyndbg's Factory macros: _dynamic_func_call_no_desc().
This adds the callsite descriptor into the code, and an entry for each
into /proc/dynamic_debug/control.
#> echo class DRM_UT_ATOMIC +p > /proc/dynamic_debug/control
CONFIG_DRM_USE_DYNAMIC_DEBUG=y/n is configurable because of the .data
footprint cost of per-callsite control; 56 bytes/site * ~2k for i915,
~4k callsites for amdgpu. This is large enough that a kernel builder
might not want it.
