But as a pre-requisite this changes coresight_platform_data structure assignment for the TRBE device. This series is based on v6.5-rc5 kernel, is also dependent on the following EDK2 changes posted earlier by Sami. https://edk2.groups.io/g/devel/message/107239 https://edk2.groups.io/g/devel/message/107241 Changes in V5: - Detected zeroed parsed GSI as a mismatch but handled all zero scenario - Changed condition check from 'if (ret < 0)' into a 'if (ret)' - Dropped pr_warn() message after platform_device_register() Changes in V4: https://lore.kernel.org/all/20230808082247.383405-1-anshuman.khandual@arm.com/ - Added in-code comment for arm_trbe_device_probe() - Reverted back using IS_ENABLED() for SPE PMU platform device - Replaced #ifdef with IS_ENABLED() for TRBE platform device - Protected arm_trbe_acpi_match with ACPI_PTR() - preventing a build failure when CONFIG_ACPI is not enabled - Added __maybe_unused for arm_acpi_register_pmu_device() and dropped config checks with IS_ENABLED() Changes in V3: https://lore.kernel.org/all/20230803055652.1322801-1-anshuman.khandual@arm.com/ - Changed ARMV8_TRBE_PDEV_NAME from "arm-trbe-acpi" into "arm,trbe" - Dropped local variable 'matched' - Replaced 'matched' with 'valid gsi' as being already matched once - Moved find_acpi_cpu_topology_hetero_id() outside conditional check Changes in V2: https://lore.kernel.org/all/20230801094052.750416-1-anshuman.khandual@arm.com/ - Refactored arm_spe_acpi_register_device() in a separate patch - Renamed trbe_acpi_resources as trbe_resources - Renamed trbe_acpi_dev as trbe_dev Changes in V1: https://lore.kernel.org/all/20230728112733.359620-1-anshuman.khandual@arm.com/ Cc: Sami Mujawar Cc: Catalin Marinas Cc: Will Deacon Cc: Mark Rutland Cc: Suzuki K Poulose Cc: Mike Leach Cc: Leo Yan Cc: Alexander Shishkin Cc: James Clark Cc: coresight@lists.linaro.org Cc: linux-arm-kernel@lists.infradead.org Cc: linux-kernel@vger.kernel.org Anshuman Khandual (4): arm_pmu: acpi: Refactor arm_spe_acpi_register_device() arm_pmu: acpi: Add a representative platform device for TRBE coresight: trbe: Add a representative coresight_platform_data for TRBE coresight: trbe: Enable ACPI based TRBE devices arch/arm64/include/asm/acpi.h | 3 + drivers/hwtracing/coresight/coresight-trbe.c | 26 +++- drivers/hwtracing/coresight/coresight-trbe.h | 2 + drivers/perf/arm_pmu_acpi.c | 142 ++++++++++++++----- include/linux/perf/arm_pmu.h | 1 + 5 files changed, 132 insertions(+), 42 deletions(-) -- 2.25.1
