Subject: [PATCH 0/5] Add a dirty logging performance test
Date: Tue, 27 Oct 2020 16:37:28 -0700 [thread overview]
Message-ID: <20201027233733.1484855-1-bgardon@google.com> (raw)
Currently KVM lacks a simple, userspace agnostic, performance benchmark for
dirty logging. Such a benchmark will be beneficial for ensuring that dirty
logging performance does not regress, and to give a common baseline for
validating performance improvements. The dirty log perf test introduced in
this series builds on aspects of the existing demand paging perf test and
provides time-based performance metrics for enabling and disabling dirty
logging, getting the dirty log, and dirtying memory.
While the test currently only has a build target for x86, I expect it will
work on, or be easily modified to support other architectures.
Ben Gardon (5):
KVM: selftests: Factor code out of demand_paging_test
KVM: selftests: Remove address rounding in guest code
KVM: selftests: Simplify demand_paging_test with timespec_diff_now
KVM: selftests: Add wrfract to common guest code
KVM: selftests: Introduce the dirty log perf test
