Subject: [PATCH v3 16/21] kselftest/arm64: Enumerate SME2 in the signal test utility code
Date: Fri, 11 Nov 2022 21:50:21 +0000 [thread overview]
Message-ID: <20221111215026.813348-17-broonie@kernel.org> (raw)
In-Reply-To: <20221111215026.813348-1-broonie@kernel.org>
Support test cases for SME2 by adding it to the set of features that we
enumerate so test cases can check for it.
Signed-off-by: Mark Brown <broonie@kernel.org>
