The limit removed in sis and tsim is the simulated cpu time used. If not using

Replacing these with a command line argument is probably good but just removing
these mean these simulators will just run much longer before being killed.
How best to capture the distinction between target run time and host run time?
Thank you for the explanation. I was not sure how the option effected things and
yes it does matter we have this set correctly.
Options can be set in the $HOME/.rtemstesterrc is via the --user-config option.
Maybe this can be used to control the time out for specific user tests?
I would not make this more complicated than necessary. We have a --timeout
command line option and the default timeout value can be set by *.ini files. The
simulator speed is just a detail similar to running a target at 100MHz or 1GHz.
It is actually simpler to have this option and to measure time against the cpu
time. The work loads on SMP hosts with qemu shows simulation timeouts are
difficult to get right.
I don't know what is wrong with the patch. Overruling command line
options is just bad.
Sebastian, are some of the standard testsuite test's failing because of this
setting?
Yes, with -O0 and code coverage enabled the tests run longer than usual.
Looks to me like the timeout may need to be adjusted?
One of the performance tests needed 14 minutes on a fast computer. I
would keep the timeouts as is for now. There is more work to do before
the gcov coverage is generally usable.
