Hi all,
I was curious about whether a context switch in Linux saves and restores
the MSR registers of the tasks involved in the context switch. I
searched in the source code and could not find this functionality. I'm
not sure if all MSRs need or can be associated to tasks but I understand
that, for example, MSRs related to performance counters should be saved
and restored on context switches to correctly monitor events on a per
PID basis.
Thanks a lot,
Josué
