[PATCH v6 0/3] KVM: selftests: randomize memory access of dirty_log_perf_test

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

 



Add the ability to randomize parts of dirty_log_perf_test,
specifically the order pages are accessed and whether pages are read
or written.

v6:

Change default random seed to the constant 0.

Explain why 100% writes in populate phase, why no random access in
populate phase, and why use two random numbers in the guest code.

Colton Lewis (3):
  KVM: selftests: implement random number generation for guest code
  KVM: selftests: randomize which pages are written vs read
  KVM: selftests: randomize page access order
