Subject: [RFC][PATCH 06/10] irq/tracing: Export enums in tracepoints to user space
Date: Fri, 27 Mar 2015 17:37:10 -0400 [thread overview]
Message-ID: <20150327213814.093910128@goodmis.org> (raw)
In-Reply-To: 20150327213704.857765144@goodmis.org
[-- Attachment #1: 0006-irq-tracing-Export-enums-in-tracepoints-to-user-spac.patch --]
[-- Type: text/plain, Size: 2075 bytes --]
From: "Steven Rostedt (Red Hat)" <rostedt@goodmis.org>
The enums used by the softirq mapping is what is shown in the output
of the __print_symbolic() and not their values, that are needed
to map them to their strings. Export them to userspace with the
TRACE_DEFINE_ENUM() macro so that user space tools can map the enums
with their values.
