Subject: [PATCH v4 7/7] amdgpu: define a dydbg-bitmap to control categorized pr_debugs
Date: Sat, 31 Jul 2021 15:42:04 -0600 [thread overview]
Message-ID: <20210731214211.657280-8-jim.cromie@gmail.com> (raw)
In-Reply-To: <20210731214211.657280-1-jim.cromie@gmail.com>
logger_types.h defines many DC_LOG_*() categorized debug wrappers.
Many of these use DRM_DEBUG_*, so are controllable using drm.debug,
but others use bare pr_debug()s, each with a different class-prefix
matching "^[\w+]:"
Use DYNDBG_BITMAP_DESC() to create a parameter/debug_dc, and to define
bits to control those pr_debugs by their category.
