Subject: [PATCH v2 7/9] arm64/hwcap: Describe 2024 dpISA extensions to userspace
Date: Wed, 30 Oct 2024 15:34:52 +0000 [thread overview]
Message-ID: <20241030-arm64-2024-dpisa-v2-7-b6601a15d2a5@kernel.org> (raw)
In-Reply-To: <20241030-arm64-2024-dpisa-v2-0-b6601a15d2a5@kernel.org>
The 2024 dpISA introduces a number of architecture features all of which
only add new instructions so only require the addition of hwcaps and ID
register visibility.
