second This patch adds support for getopt, and adds two default parameters to it: -h to show usage notes; and -s to allow user to define number of samples to acquire per second. Manpage documentation is also adjusted accordingly. Signed-off-by: Eugeni Dodonov <eugeni.dodonov@intel.com>

Note that idle units are not

displayed, so an entirely idle GPU will only display the ring status and
|
|
header.
|
|
.SH BUGS
|
|
Some GPUs report some units as busy when they aren't, such that even when
|
|
idle and not hung, it will show up as 100% busy.
