Subject: [PATCH v1 37/38] selftests: arm64: Add streaming SVE to SVE ptrace tests
Date: Thu, 30 Sep 2021 19:11:43 +0100	[thread overview]
Message-ID: <20210930181144.10029-38-broonie@kernel.org> (raw)
In-Reply-To: <20210930181144.10029-1-broonie@kernel.org>

In order to allow ptrace of streaming mode SVE registers we have added a
new regset for streaming mode which in isolation offers the same ABI as
regular SVE with a different vector type. Add this to the array of regsets
we handle, together with additional tests for the interoperation of the
two regsets.
