[PATCH v3 09/24] tests: Add test infrastructure for qemuMonitorGetCPUInfo

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

 



As the combination algorithm is rather complex and ugly it's necessary
to make sure it works properly. Add test suite infrastructure for
testing it along with a basic test based on x86_64 platform.

    - shortened very long line
    - already ACKed
