[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.

From: Arnd Bergmann <arnd(a)arndb.de> Functions that are annotated __exit are discarded for built-in drivers, but the .remove callback in a device driver must still be kept around to allow bind/unbind operations. There is now a linker warning for the discarded symbol references: `tmc_remove' referenced in section `.data' of drivers/hwtracing/coresight/coresight-tmc-core.o: defined in discarded section `.exit.text' of drivers/hwtracing/coresight/coresight-tmc-core.o `tpiu_remove' referenced in section `.data' of drivers/hwtracing/coresight/coresight-tpiu.o: defined in discarded section `.exit.text' of drivers/hwtracing/coresight/coresight-tpiu.o `etb_remove' referenced in section `.data' of drivers/hwtracing/coresight/coresight-etb10.o: defined in discarded section `.exit.text' of drivers/hwtracing/coresight/coresight-etb10.o `static_funnel_remove' referenced in section `.data' of drivers/hwtracing/coresight/coresight-funnel.o: defined in discarded section `.exit.text' of drivers/hwtracing/coresight/coresight-funnel.o `dynamic_funnel_remove' referenced in section `.data' of drivers/hwtracing/coresight/coresight-funnel.o: defined in discarded section `.exit.text' of drivers/hwtracing/coresight/coresight-funnel.o `static_replicator_remove' referenced in section `.data' of drivers/hwtracing/coresight/coresight-replicator.o: defined in discarded section `.exit.text' of drivers/hwtracing/coresight/coresight-replicator.o `dynamic_replicator_remove' referenced in section `.data' of drivers/hwtracing/coresight/coresight-replicator.o: defined in discarded section `.exit.text' of drivers/hwtracing/coresight/coresight-replicator.o `catu_remove' referenced in section `.data' of drivers/hwtracing/coresight/coresight-catu.o: defined in discarded section `.exit.text' of drivers/hwtracing/coresight/coresight-catu.o Remove all those annotations.
