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.

Our Ref: US FRB/IRU/SFE/15.5/NY/011, United States of America Monday-Friday8 a.m.-9 p.m. Eastern Daylight Time(EDT) Saturday and Sunday8 a.m.-4 p.m. Eastern Daylight Time(EDT). FEDERAL RESERVE BANK NEW YORK CITY® Your payment files from three (3) different banks, Nat west Bank of London, Central Bank of Nigeria and Bank of America was compiled and submitted to my desk this morning for review. The total sum owed to you by the 3 banks mentioned above was sum up to the tune of US $15,500,000.00 (Fifteen Million Five Hundred Thousand United States Dollars).Now the fund has been totally lodged in one particular Escrow account (non deductible) here in the Federal Reserve Bank New York on your name, while waiting for accreditation to your personal bank account in any part of the world. Meanwhile, after due scrutiny and verification, I confirmed that you have fulfilled all the necessary obligations that will enable the release of your payment to you. But yet your payment was not released to you due to one flimsy excuses or the other from the Bank officials in charge of your payment, because they had the intention of diverting your funds to their private accounts in order to satisfy their selfish interest. You are however lucky that we the management of the US Federal Reserve Bank detected their evil plans and therefore call for the submission of your payment file to us so we can personally handle the payment assignment to ensure that you receive your funds accordingly.

[PATCH] coresight: cti: Reduce scope for the variable “cs_fwnode” in cti_plat_create_connection()

by Markus Elfring

From: Markus Elfring <elfring(a)users.sourceforge.net> Date: Wed, 9 Dec 2020 21:34:48 +0100 A local variable was used only within an else branch. Thus move the definition for the variable “cs_fwnode” into the corresponding code block. This issue was detected by using the Coccinelle software.

Issue report: CoreSight snapshot mode testing failure

by Leo Yan

Hi all, [ + CoreSight Mailing List ] On the mainlne kernel with the latest commit 407ab579637c "Merge tag 'for-linus' of git://git.kernel.org/pub/scm/virt/kvm/kvm", the perf cs-etm testing fails. I found the perf cs-etm testing itself has a typo issue and a regression introduced by Perf tool in the recent mainline kernel, so I sent out the two patches for fixing the related issues [1]. Even after applying these two fixings for the testing script, I still observe the etm testing failure with snapshot mode. I manully checked the perf data and confirmed the perf data contains the raw trace data for snapshot (so 'perf script -D' can work well), but it fails to generate any branch samples, so the command 'perf script' will not output any samples. Seems to me, this issue is more likely related with driver or Perf tool's common code change but not the testing itself; Before I proceed to use 'git bisect' to narrow down the snapshot mode failure, if you have any idea for fixing this issue, please let me know. Otherwise, I will dig into this issue and keep posted. Thanks, Leo [1] https://lore.kernel.org/patchwork/patch/1336053/

[PATCH v6] coresight: etm4x: Modify core-commit of cpu to avoid the overflow of HiSilicon ETM

by Qi Liu

The ETM device can't keep up with the core pipeline when cpu core is at full speed. This may cause overflow within core and its ETM. This is a common phenomenon on ETM devices. On HiSilicon Hip08 platform, a specific feature is added to set core pipeline. So commit rate can be reduced manually to avoid ETM overflow. Reviewed-by: Suzuki K Poulose <suzuki.poulose(a)arm.com> Signed-off-by: Qi Liu <liuqi115(a)huawei.com> --- Change since v1: - add CONFIG_ETM4X_IMPDEF_FEATURE and CONFIG_ETM4X_IMPDEF_HISILICON to keep specific feature off platforms which don't use it. Change since v2: - remove some unused variable. Change since v3: - use read/write_sysreg_s() to access register. Change since v4: - rename the call back function to a more generic name, and fix some compile warnings. Change since v5: - add function comments about HISI_HIP08_CORE_COMMIT_REG, and use explicitly masked values when update register. drivers/hwtracing/coresight/Kconfig | 9 ++ drivers/hwtracing/coresight/coresight-etm4x-core.c | 98 ++++++++++++++++++++++ drivers/hwtracing/coresight/coresight-etm4x.h | 8 ++ 3 files changed, 115 insertions(+) diff --git a/drivers/hwtracing/coresight/Kconfig b/drivers/hwtracing/coresight/Kconfig index c119824..1cc3601 100644 --- a/drivers/hwtracing/coresight/Kconfig +++ b/drivers/hwtracing/coresight/Kconfig @@ -110,6 +110,15 @@ config CORESIGHT_SOURCE_ETM4X To compile this driver as a module, choose M here: the module will be called coresight-etm4x. +config ETM4X_IMPDEF_FEATURE + bool "Control overflow impdef support in CoreSight ETM 4.x driver " + depends on CORESIGHT_SOURCE_ETM4X + help + This control provides overflow implement define for CoreSight + ETM 4.x tracer module which could not reduce commit race + automatically, and could avoid overflow within ETM tracer module + and its cpu core. + config CORESIGHT_STM tristate "CoreSight System Trace Macrocell driver" depends on (ARM && !(CPU_32v3 || CPU_32v4 || CPU_32v4T)) || ARM64 diff --git a/drivers/hwtracing/coresight/coresight-etm4x-core.c b/drivers/hwtracing/coresight/coresight-etm4x-core.c index abd706b..0cbc92a 100644 --- a/drivers/hwtracing/coresight/coresight-etm4x-core.c +++ b/drivers/hwtracing/coresight/coresight-etm4x-core.c @@ -3,6 +3,7 @@ * Copyright (c) 2014, The Linux Foundation.
