Subject: [PATCH v5 36/38] kselftest/arm64: Add streaming SVE to SVE ptrace tests
Date: Wed, 27 Oct 2021 19:44:22 +0100 [thread overview]
Message-ID: <20211027184424.166237-37-broonie@kernel.org> (raw)
In-Reply-To: <20211027184424.166237-1-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.
