Subject: [PATCH 00/10] arm64: Self-hosted trace related erratum workarouds
Date: Wed, 28 Jul 2021 14:52:07 +0100 [thread overview]
Message-ID: <20210728135217.591173-1-suzuki.poulose@arm.com> (raw)
This series adds CPU erratum work arounds related to the self-hosted
tracing. The list of affected errata handled in this series are :
* TRBE may overwrite trace in FILL mode
- Arm Neoverse-N2 #2139208
- Cortex-A710 #2119858
* A TSB instruction may not flush the trace completely when executed
in trace prohibited region.
- Arm Neoverse-N2 #2067961
- Cortex-A710 #2054223
The series applies on the self-hosted/trbe fixes posted here [0].
A tree containing both the series is available here [1].

Suzuki K Poulose (10):
coresight: trbe: Add infrastructure for Errata handling
coresight: trbe: Add a helper to calculate the trace generated
coresight: trbe: Add a helper to pad a given buffer area
coresight: trbe: Decouple buffer base from the hardware base

arm64: Add Neoverse-N2, Cortex-A710 CPU part definition
arm64: Add erratum detection for TRBE overwrite in FILL mode
coresight: trbe: Workaround TRBE errat overwrite in FILL mode
arm64: Enable workaround for TRBE overwrite in FILL mode
arm64: errata: Add workaround for TSB flush failures
