This patchset does 3 main things.
Adds DEFINE_DYNAMIC_DEBUG_CATEGORIES to define bitmap => category
control of pr_debugs, and to create their sysfs entries.
Uses it in amdgpu, i915 to control existing pr_debugs according to
their ad-hoc categorizations.
Plugs dyndbg into drm-debug framework, in a configurable manner.
v6: cleans up per v5 feedback, and adds RFC stuff:
- test_dynamic_debug.ko: uses tracer facility added in v5:8/9
- prototype print-once & rate-limiting
Hopefully adding RFC stuff doesnt distract too much.
Jim Cromie (11):
moduleparam: add data member to struct kernel_param
dyndbg: add DEFINE_DYNAMIC_DEBUG_CATEGORIES and callbacks
i915/gvt: remove spaces in pr_debug "gvt: core:" etc prefixes
i915/gvt: use DEFINE_DYNAMIC_DEBUG_CATEGORIES to create "gvt:core:"
etc categories
amdgpu: use DEFINE_DYNAMIC_DEBUG_CATEGORIES to control categorized
pr_debugs
drm_print: add choice to use dynamic debug in drm-debug
drm_print: instrument drm_debug_enabled
amdgpu_ucode: reduce number of pr_debug calls
nouveau: fold multiple DRM_DEBUG_DRIVERs together
dyndbg: RFC add debug-trace callback, selftest with it. RFC
dyndbg: RFC add print-once and print-ratelimited features. RFC.
