dear all,

I have questions about priority inversion condition in realtime system:

1. Is it right that priority inversion condition will be a problem only if
its duration is unbound

2. what is the differences beetwen pcp (priority ceiling protocol), its
emulation, and pip (priority inheritance protocol) because they are same
to me as all of them give the highest process' priority, that are blocked
for a resource, to a process that have lock for that resource so that the
process can't be preempted by any intermediate process.

3. is it right that for rtlinux, priority inversion problem solutions are
hacking and can cause another problems so leave that condition is better
than solve them

thanks
