[PATCH v6 22/22] drm-drivers: DRM_CLASSMAP_USE in 2nd batch of drivers, helpers

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



Add a DRM_CLASSMAP_USE declaration to 2nd batch of helpers and *_drv.c
files.  For drivers, add the decl just above the module's PARAMs,
since it identifies the "inherited" drm.debug param.

Note: with CONFIG_DRM_USE_DYNAMIC_DEBUG=y, a module not also declaring
DRM_CLASSMAP_USE will have its class'd prdbgs stuck in the initial
(disabled, but for DEBUG) state.

The stuck sites are evident in /proc/dynamic_debug/control as:

   class unknown, _id:N		# control's last column

rather than a proper "enumeration":

   class:DRM_UT_CORE

This set of updates was found by choosing M for all DRM-config items I
found (not allmodconfig), building & modprobing them, and grepping
"class unknown," control.  There may yet be others.
