[PATCH kvm-unit-tests 0/2] arm/arm64: smp: on_cpu improvements

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



After posting on_cpu() support yesterday I thought of some potential
issues.
 1) cpu0 was the only cpu allowed to call on_cpus, and no cpu was
    allowed to call on_cpu on cpu0 (as it'll never idle).
 2) deadlocks are easy with this idle state scheduling model, but
    also easy to detect, so we should.

Andrew Jones (2):
  arm/arm64: smp: cpu0 is special
  arm/arm64: smp: add deadlock detection
