Subject: [PATCH v2 0/2] arm64: Implement support for 2025 dpISA extensions
Date: Mon, 18 May 2026 16:07:28 +0100	[thread overview]
Message-ID: <20260518-arm64-dpisa-2025-v2-0-b3367b73bd00@kernel.org> (raw)

The 2025 dpISA extensions introduce a number of architecture features
all of which are fairly straightforward from a kernel point of view
since they only introduce new instructions, not any architecture state.

Signed-off-by: Mark Brown <broonie@kernel.org>

Changes in v2:
- Rename HWCAP3_LUT6 to HWCAP3_SVE_LUT6 and make it depend on SVE.
- Rebase onto v7.1-rc3.
- Link to v1: https://patch.msgid.link/20260302-arm64-dpisa-2025-v1-0-0855e7f41689@kernel.org
