From 84ec67288c10fbf136aa050d00b0fe7a89655da0 Mon Sep 17 00:00:00 2001 From: Jim Cromie Date: Sun, 11 Sep 2022 23:28:47 -0600 Subject: 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.
