[PATCH 1/2] perf cs-etm: Change tuple from traceID-CPU# to traceID-metadata

by Salvatore Bonaccorso

From: Leo Yan <leo.yan(a)linaro.org> commit 95c6fe970a0160cb770c5dce9f80311b42d030c0 upstream. If packet processing wants to know the packet is bound with which ETM version, it needs to access metadata to decide that based on metadata magic number; but we cannot simply to use CPU logic ID number as index to access metadata sequential array, especially when system have hotplugged off CPUs, the metadata array are only allocated for online CPUs but not offline CPUs, so the CPU logic number doesn't match with its index in the array. This patch is to change tuple from traceID-CPU# to traceID-metadata, thus it can use the tuple to retrieve metadata pointer according to traceID. For safe accessing metadata fields, this patch provides helper function cs_etm__get_cpu() which is used to return CPU number according to traceID; cs_etm_decoder__buffer_packet() is the first consumer for this helper function.

Cross-compiling perf and using OpenCSD for decoding trace data not working

by Dominik Huber

Hello, I want to capture and decode trace data on a Hikey620 (on Target) with OpenCSD and perf. I have been trying different kernels, compilers and compile options for weeks already, but I can not get it working. If anybody could take a look at my current build process or just provide me a tested combination of kernel, config and compiler, it would be very helpful. I have to cross compile its kernel (and therefore also tools/perf) on a host computer. For that I use a docker container to ensure I have a clean and controlled system. When compiling tools/perf I always get "libopencsd: [ OFF ]", and when executing "perf report" on target I get this error: 178 [0x268]: failed to process type: 70 Error: failed to process sample Therefore I suspect the building process of OpenCSD or tools/perf to be the problem. Trace collection without perf and OpenCSD works just fine. My current build process is: Installing OpenCSD on host: cd OpenCSD/decoder/build/linux/ make -f makefile.dev DEBUG=1 ARCH=arm64 make -f makefile.dev DEBUG=1 ARCH=arm64 install Building kernel on host: cd coresight make -j8 ARCH=arm64 CROSS_COMPILE=aarch64-linux-gnu- Image modules hisilicon/hi6220-hikey.dtb O=./out make INSTALL_MOD_PATH=./modules modules_install O=./out Building /tools/perf on host: mkdir coresight/out/perf make ARCH=arm64 CROSS_COMPILE=aarch64-linux-gnu- -C tools/perf VF=1 CORESIGHT=1 O=/opt/hikey620/coresight/out/perf Installing OpenCSD on target (Hikey620): cd OpenCSD/decoder/build/linux/ make -f makefile.dev make -f makefile.dev install My compiler is the "gcc-linaro-7.5.0-2019.12-x86_64_aarch64-linux-gnu" from Linaro My kernel is the one from Mathieu Poirier: https://git.linaro.org/people/mathieu.poirier/coresight.git (5.1-rc3-cpu-wide-v3) My .config was created by make ARCH=arm64 CROSS_COMPILE=aarch64-linux-gnu- defconfig but whith CoreSight and ARCH_MXC enabled: CONFIG_CORESIGHT=y CONFIG_CORESIGHT_LINKS_AND_SINKS=y CONFIG_CORESIGHT_LINK_AND_SINK_TMC=y CONFIG_CORESIGHT_CATU=y CONFIG_CORESIGHT_SINK_TPIU=y CONFIG_CORESIGHT_SINK_ETBV10=y CONFIG_CORESIGHT_SOURCE_ETM4X=y CONFIG_CORESIGHT_DYNAMIC_REPLICATOR=y CONFIG_CORESIGHT_STM=y CONFIG_CORESIGHT_CPU_DEBUG=y CONFIG_ARCH_MXC=y Thanks, Dominik Huber

perf issue: etm traces are dumped to the wrong AUX buffer

by Zied Guermazi

hi I am using perf syscall to collect etm traces for btraces implementation in GDB running on Linux kernel 5.9.1 on a cortex A7. in this test case, I am debugging a multi-threaded process (2 pthreads). For each thread, GDB is calling the sys call perf_event_open and gives the corresponding thread ptid.lwp as argument. for each syscall, the AUX buffer is mmap(ped) to a dedicated memory. this is working for almost all test cases I have, except this one, where it has 50% failure rate when executed manually. 90% failure rate when executed from a script. the source code for debugged program is listed below. /* This testcase is part of GDB, the GNU debugger.

[RFC 00/11] arm64: coresight: Enable ETE and TRBE

by Anshuman Khandual

This series enables future IP trace features Embedded Trace Extension (ETE) and Trace Buffer Extension (TRBE). This series depends on the ETM system register instruction support series [0] and the v8.4 Self hosted tracing support series (Jonathan Zhou) [1]. The tree is available here [2] for quick access. ETE is the PE (CPU) trace unit for CPUs, implementing future architecture extensions. ETE overlaps with the ETMv4 architecture, with additions to support the newer architecture features and some restrictions on the supported features w.r.t ETMv4. The ETE support is added by extending the ETMv4 driver to recognise the ETE and handle the features as exposed by the TRCIDRx registers. ETE only supports system instructions access from the host CPU. The ETE could be integrated with a TRBE (see below), or with the legacy CoreSight trace bus (e.g, ETRs). Thus the ETE follows same firmware description as the ETMs and requires a node per instance. Trace Buffer Extensions (TRBE) implements a per CPU trace buffer, which is accessible via the system registers and can be combined with the ETE to provide a 1x1 configuration of source & sink. TRBE is being represented here as a CoreSight sink. Primary reason is that the ETE source could work with other traditional CoreSight sink devices. As TRBE captures the trace data which is produced by ETE, it cannot work alone. TRBE representation here have some distinct deviations from a traditional CoreSight sink device. Coresight path between ETE and TRBE are not built during boot looking at respective DT or ACPI entries. Instead TRBE gets checked on each available CPU, when found gets connected with respective ETE source device on the same CPU, after altering its outward connections. ETE TRBE path connection lasts only till the CPU is online. But ETE-TRBE coupling/decoupling method implemented here is not optimal and would be reworked later on. Unlike traditional sinks, TRBE can generate interrupts to signal including many other things, buffer got filled. The interrupt is a PPI and should be communicated from the platform. DT or ACPI entry representing TRBE should have the PPI number for a given platform. During perf session, the TRBE IRQ handler should capture trace for perf auxiliary buffer before restarting it back. System registers being used here to configure ETE and TRBE could be referred in the link below. https://developer.arm.com/docs/ddi0601/g/aarch64-system-registers. This adds another change where CoreSight sink device needs to be disabled before capturing the trace data for perf in order to avoid race condition with another simultaneous TRBE IRQ handling. This might cause problem with traditional sink devices which can be operated in both sysfs and perf mode. This needs to be addressed correctly. One option would be to move the update_buffer callback into the respective sink devices. e.g, disable(). This series is primarily looking from some early feed back both on proposed design and its implementation. It acknowledges, that it might be incomplete and will have scopes for improvement. Things todo: - Improve ETE-TRBE coupling and decoupling method - Improve TRBE IRQ handling for all possible corner cases - Implement sysfs based trace sessions [0] https://lore.kernel.org/linux-arm-kernel/20201028220945.3826358-1-suzuki.po… [1] https://lore.kernel.org/linux-arm-kernel/1600396210-54196-1-git-send-email-… [2] https://gitlab.arm.com/linux-arm/linux-skp/-/tree/coresight/etm/v8.4-self-h… Anshuman Khandual (6): arm64: Add TRBE definitions coresight: sink: Add TRBE driver coresight: etm-perf: Truncate the perf record if handle has no space coresight: etm-perf: Disable the path before capturing the trace data coresgith: etm-perf: Connect TRBE sink with ETE source dts: bindings: Document device tree binding for Arm TRBE Suzuki K Poulose (5): 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 sysreg support coresight: ete: Detect ETE as one of the supported ETMs .../devicetree/bindings/arm/coresight.txt | 3 + Documentation/devicetree/bindings/arm/trbe.txt | 20 + Documentation/trace/coresight/coresight-trbe.rst | 36 + arch/arm64/include/asm/sysreg.h | 51 ++ drivers/hwtracing/coresight/Kconfig | 11 + drivers/hwtracing/coresight/Makefile | 1 + drivers/hwtracing/coresight/coresight-etm-perf.c | 85 ++- drivers/hwtracing/coresight/coresight-etm-perf.h | 4 + drivers/hwtracing/coresight/coresight-etm4x-core.c | 144 +++- drivers/hwtracing/coresight/coresight-etm4x.h | 64 +- drivers/hwtracing/coresight/coresight-platform.c | 9 +- drivers/hwtracing/coresight/coresight-trbe.c | 768 +++++++++++++++++++++ drivers/hwtracing/coresight/coresight-trbe.h | 525 ++++++++++++++ include/linux/coresight.h | 2 + 14 files changed, 1680 insertions(+), 43 deletions(-) create mode 100644 Documentation/devicetree/bindings/arm/trbe.txt 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 -- 2.7.4
