Subject: [PATCH v7 00/16] Support Andes PMU extension
Date: Wed, 10 Jan 2024 15:39:01 +0800 [thread overview]
Message-ID: <20240110073917.2398826-1-peterlin@andestech.com> (raw)
Hi All,
This patch series introduces the Andes PMU extension, which serves
the same purpose as Sscofpmf. To use FDT-based probing for hardware
support of the PMU extensions and introduce Andes PMU alternatives,
we first convert T-Head's PMU to CPU feature alternative.
Its non-standard local interrupt is assigned to bit 18 in the
custom S-mode local interrupt enable/pending registers (slie/slip),
while the interrupt cause is (256 + 18).
Linux patches based on:
- ed5b7cf ("riscv: errata: andes: Probe for IOCP only once in boot stage")
It can be found on Andes Technology GitHub:
- https://github.com/andestech/linux/commits/andes-pmu-support-v7
The PMU device tree node used on AX45MP:
- https://github.com/riscv-software-src/opensbi/blob/master/docs/pmu_support.md#example-3
