Subject: [PATCH 3/3] xenalyze: handle RTDS scheduler events
Date: Sat, 12 Mar 2016 12:34:13 +0100 [thread overview]
Message-ID: <20160312113412.14480.53700.stgit@Solace.station> (raw)
In-Reply-To: <20160312112621.14480.21747.stgit@Solace.station>
so the trace will show properly decoded info,
rather than just a bunch of hex codes.

Changes from v2:
* use 64 bits ints for time values (now that the scheduler
does that too), as suggested during review.
Changes from v1:
* '} * r =' turned into '} *r =', as requested
during review.
