This enables OpenSBI to expose the SBI PMU extension, allowing Linux perf to use the 4 programmable counters (mhpmcounter3-6) across 3 event classes: instruction commit, microarchitectural, and memory system events. Extend the RISC-V IOMMU device tree bindings to document the Tenstorrent IOMMU used in the Tenstorrent Atlantis SoC. A second register range is added which contains M-mode only registers like PMAs and PMPs. The binding will be used by OpenSBI and potentially other M-mode software. ---------------------------------------------------------------- Michael Neuling (1): riscv: dts: tenstorrent: Add PMU node to blackhole for Linux perf support Nicholas Piggin (1): dt-bindings: iommu: riscv: Add bindings for Tenstorrent RISC-V IOMMU .../devicetree/bindings/iommu/riscv,iommu.yaml | 59 +++++++++++++++++++--- arch/riscv/boot/dts/tenstorrent/blackhole.dtsi | 48 ++++++++++++++++++ 2 files changed, 99 insertions(+), 8 deletions(-)
