The following changes since commit a354a64d91eec3e0f8ef0eed575b480fd75b999c: KVM: arm64: Disable guest access to trace filter controls (2021-03-24 17:26:38 +0000) are available in the Git repository at: git@xxxxxxxxxxxxxxxxxxx:pub/scm/linux/kernel/git/coresight/linux.git next-ETE-TRBE for you to fetch changes up to 7885b4e43231048654c5a80c0a18844ce3185e64: dts: bindings: Document device tree bindings for Arm TRBE (2021-04-05 11:38:04 -0600) ---------------------------------------------------------------- Hi Marc, As previously agreed, here are the changes to support CoreSight ETE and TRBE components submitted here[1]. I draw your attention to these: [PATCH v6 05/20] kvm: arm64: Handle access to TRFCR_EL1 [PATCH v6 06/20] kvm: arm64: Move SPE availability check to VCPU load [PATCH v6 07/20] arm64: kvm: Enable access to TRBE support for host They are KVM specific and will need an SoB tag. Thanks, Mathieu [1]. https://lore.kernel.org/linux-arm-kernel/20210405164307.1720226-1-suzuki.poulose@xxxxxxx/T/#t ---------------------------------------------------------------- Anshuman Khandual (5): arm64: Add TRBE definitions coresight: core: Add support for dedicated percpu sinks coresight: sink: Add TRBE driver Documentation: coresight: trbe: Sysfs ABI description Documentation: trace: Add documentation for TRBE Suzuki K Poulose (15): perf: aux: Add flags for the buffer format perf: aux: Add CoreSight PMU buffer formats arm64: Add support for trace synchronization barrier kvm: arm64: Handle access to TRFCR_EL1 kvm: arm64: Move SPE availability check to VCPU load arm64: kvm: Enable access to TRBE support for host coresight: etm4x: Move ETM to prohibited region for disable coresight: etm-perf: Allow an event to use different sinks coresight: Do not scan for graph if none is present coresight: etm4x: Add support for PE OS lock coresight: ete: Add support for ETE sysreg access coresight: ete: Add support for ETE tracing dts: bindings: Document device tree bindings for ETE coresight: etm-perf: Handle stale output handles dts: bindings: Document device tree bindings for Arm TRBE .../ABI/testing/sysfs-bus-coresight-devices-trbe | 14 + Documentation/devicetree/bindings/arm/ete.yaml | 75 ++ Documentation/devicetree/bindings/arm/trbe.yaml | 49 + Documentation/trace/coresight/coresight-trbe.rst | 38 + MAINTAINERS | 2 + arch/arm64/include/asm/barrier.h | 1 + arch/arm64/include/asm/el2_setup.h | 13 + arch/arm64/include/asm/kvm_arm.h | 2 + arch/arm64/include/asm/kvm_host.h | 8 + arch/arm64/include/asm/sysreg.h | 50 + arch/arm64/kernel/hyp-stub.S | 3 +- arch/arm64/kvm/arm.c | 2 + arch/arm64/kvm/debug.c | 35 +- arch/arm64/kvm/hyp/nvhe/debug-sr.c | 56 +- arch/arm64/kvm/hyp/nvhe/switch.c | 1 + arch/arm64/kvm/sys_regs.c | 1 + drivers/hwtracing/coresight/Kconfig | 24 +- drivers/hwtracing/coresight/Makefile | 1 + drivers/hwtracing/coresight/coresight-core.c | 29 +- drivers/hwtracing/coresight/coresight-etm-perf.c | 119 +- drivers/hwtracing/coresight/coresight-etm4x-core.c | 161 ++- .../hwtracing/coresight/coresight-etm4x-sysfs.c | 19 +- drivers/hwtracing/coresight/coresight-etm4x.h | 83 +- drivers/hwtracing/coresight/coresight-platform.c | 6 + drivers/hwtracing/coresight/coresight-priv.h | 3 + drivers/hwtracing/coresight/coresight-trbe.c | 1157 ++++++++++++++++++++ drivers/hwtracing/coresight/coresight-trbe.h | 152 +++ include/linux/coresight.h | 13 + include/uapi/linux/perf_event.h | 13 +- 29 files changed, 2053 insertions(+), 77 deletions(-) create mode 100644 Documentation/ABI/testing/sysfs-bus-coresight-devices-trbe create mode 100644 Documentation/devicetree/bindings/arm/ete.yaml create mode 100644 Documentation/devicetree/bindings/arm/trbe.yaml create mode 100644 Documentation/trace/coresight/coresight-trbe.rst create mode 100644 drivers/hwtracing/coresight/coresight-trbe.c create mode 100644 drivers/hwtracing/coresight/coresight-trbe.h _______________________________________________ kvmarm mailing list kvmarm@xxxxxxxxxxxxxxxxxxxxx https://lists.cs.columbia.edu/mailman/listinfo/kvmarm
