[PATCH v2 1/3] Documentation: KUnit: make usage.rst a superset of tips.rst, remove duplication

by Daniel Latypov

usage.rst had most of the content of the tips.rst page copied over. But it's missing https://www.kernel.org/doc/html/v6.0/dev-tools/kunit/tips.html#customizing-… Copy it over so we can retire tips.rst w/o losing content. And in that process, it also gained a duplicate section about how KUNIT_ASSERT_*() exit the test case early. Remove that.

Maybe a convenience switch to Clang/target bpf? :-) I added the same thing selftests/bpf have in their Makefile [2] and that highlighted another issue which is that selftests/net/bpf depends on bpf_helpers.h which in turn depends on the generated file bpf_helper_defs.h...

[PATCH 1/2] KVM: selftests: Allow >1 guest mode in access_tracking_perf_test

by Oliver Upton

As the name implies, for_each_guest_mode() will run the test case for all supported guest addressing modes. On x86 that doesn't amount to anything, but arm64 can handle 4K, 16K, and 64K page sizes on supporting hardware. Blindly attempting to run access_tracking_perf_test on arm64 stalls on the second test case, as the 'done' global remains set between test iterations. Clear it after VM teardown in anticipation of a subsequent test case.

test_cpuset_prs.sh is failing with the following error: test_cpuset_prs.sh: line 29: [[: 8 57%: syntax error in expression (error token is "57%") This is happening because `lscpu | grep "^CPU(s)"` returns two lines in some systems (such as Debian unstable): # lscpu | grep "^CPU(s)" CPU(s): 8 CPU(s) scaling MHz: 55% This is a simple fix that discard the second line.
