Subject: [PATCH v2 0/2] arm64: Add decode of ISS2 to data abort reports
Date: Mon, 08 May 2023 22:50:08 +0900 [thread overview]
Message-ID: <20230417-arm64-iss2-dabt-decode-v2-0-84e1c1463d30@kernel.org> (raw)
We provide fairly detailed decode of ESR for data aborts but do not
currently cover the information reported in ISS2 which has had quite a
bit of additional information added to it by recent architecture
extensions. Add decode for this information to aid in debugging, for
completeness including features we don't actually use yet.
Signed-off-by: Mark Brown <broonie@kernel.org>

Changes in v2:
- Rebase onto v6.4-rc1.
- Link to v1: https://lore.kernel.org/r/20230417-arm64-iss2-dabt-decode-v1-0-2138b5668777@kernel.org
