Subject: [PATCH 13/14] KVM: selftests: Use wildcards to find targets and test source files
Date: Tue, 13 Dec 2022 00:16:52 +0000 [thread overview]
Message-ID: <20221213001653.3852042-14-seanjc@google.com> (raw)
In-Reply-To: <20221213001653.3852042-1-seanjc@google.com>
Use $(wildcard ...) to find the test targets (.sh files) and test source
files (.c and .S) instead of manually adding files/targets for every
architecture, which is a maintenance burden and error prone, e.g. RISC-V
supports RSEQ but doesn't build the test for reasons unknown.
To deal with common tests that are only supported on a subset of
architectures, add a dummy macro TEST_UNSUPPORTED() that tests can use
to declare the test as unsupported for a given architecture, and filter
out unsupported tests for the target architecture via grep. As a bonus,
explicitly naming unsupported architectures will also force developers to
opt-out of architectures (or opt-out of tests when adding a new arch).
