Subject: [PATCH 0/4] arm64: Add workarounds for FUJITSU-MONAKA CPU
Date: Fri, 02 Oct 2026 19:26:48 +0900 [thread overview]
Message-ID: <20261002-monaka-fix-for-upstream-v1-0-4aec0b0cbe34@fujitsu.com> (raw)
This series adds three workarounds for the FUJITSU-MONAKA CPU.
- Patch 1 ... Add the FUJITSU-MONAKA CPU type definition
- Patch 2 ... Add a workaround for TLBI operation on 64k page size
- Patch 3 ... Add a workaround for perf operation
- Patch 4 ... Add a workaround for GIC operation
Although the three workarounds do not depend on each other functionally,
I have combined them into one series because patch 2 and 3
use the CPU type definition added by the first patch, and
all the workarounds update silicon-errata.rst.
If preferred, I will resend them as separate patches.
This series is based on v7.3-rc5.
Best Regards,
Tomohiro Misono
