From 3a07bae7e8539955bc3a0f4bafe82a8ff0e25fa9 Mon Sep 17 00:00:00 2001 From: Daniel Bristot de Oliveira Date: Thu, 25 Jun 2015 16:51:59 -0300 Subject: [PATCH 2/2] docs: upgrade tuna.8 man page with option -r MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Update tuna.8 man page with the descriptions of the new command line options: -r, --run="COMMAND" Run the COMMAND. If arguments are passed, the entire com‐ mand line must be provided inside "quotes". Modifiers -c and -p can be used to set the affinity and scheduler tun‐ ables of the given COMMAND. The arg[0] (i.e. the command) will be set in THREAD-LIST. Likewise the -t, the COMMAND accepts the prefix + and - as wildcards in order to be appended or removed from THREAD-LIST, respectively. And the modifications of -p behavior: -p, --priority=[POLICY:]RTPRIO Set thread scheduler tunables: POLICY and RTPRIO. POLICY is one of OTHER, FIFO, RR, or BATCH. If -t is not set, -p will act as a Modifier, saving the sched tunables for future Actions, for example -r. And -t behavior: -t, --threads=THREAD-LIST THREAD-LIST affected by commands. Requires a thread num‐ ber or thread name, or a comma-separated list of thread numbers and/or names. Thread names may contain wildcards. Be sure to quote or escape any wildcard specifications. If only - is passed as argument, the THREAD-LIST will be cleared.
