Subject: [PATCH v7 3/8] i915/gvt: use DEFINE_DYNAMIC_DEBUG_CATEGORIES to create "gvt:core:" etc categories
Date: Tue, 31 Aug 2021 14:21:28 -0600 [thread overview]
Message-ID: <20210831202133.2165222-4-jim.cromie@gmail.com> (raw)
In-Reply-To: <20210831202133.2165222-1-jim.cromie@gmail.com>
The gvt component of this driver has ~120 pr_debugs, in 9 categories
quite similar to those in DRM. Following the interface model of
drm.debug, add a parameter to map bits to these categorizations.
DEFINE_DYNAMIC_DEBUG_CATEGORIES(debug_gvt, __gvt_debug,
"dyndbg bitmap desc",
{ "gvt:cmd: ", "command processing" },
{ "gvt:core: ", "core help" },
{ "gvt:dpy: ", "display help" },
{ "gvt:el: ", "help" },
{ "gvt:irq: ", "help" },
{ "gvt:mm: ", "help" },
{ "gvt:mmio: ", "help" },
{ "gvt:render: ", "help" },
{ "gvt:sched: " "help" });
The actual patch has a few details different, cmd_help() macro emits
the initialization construct.
if CONFIG_DRM_USE_DYNAMIC_DEBUG, then -DDYNAMIC_DEBUG_MODULE is added
cflags, by gvt/Makefile.

v5:
. static decl of vector of bit->class descriptors - Emil.V
. relocate gvt-makefile chunk from elsewhere
v7:
. move ccflags addition up to i915/Makefile from i915/gvt
