[PATCH v5] 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. 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. drivers/hwtracing/coresight/Kconfig | 9 +++ drivers/hwtracing/coresight/coresight-etm4x-core.c | 88 ++++++++++++++++++++++ drivers/hwtracing/coresight/coresight-etm4x.h | 8 ++ 3 files changed, 105 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..fcee27a 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.

Al-Hashimi,I am writing to you to stand as my partner to receive my share of gratification from foreign companies whom I helped during the bidding exercise towards the Dubai World Expo 2020 Committee. Am a women and serving as a Minister, there is a limit to my personal income and investment level and For this reason, I cannot receive such a huge sum back to my country or my personal account, so an agreement was reached with the foreign companies to direct the gratifications to an open beneficiary account with a financial institution where it will be possible for me to instruct further transfer of the fund to a third party account for investment purpose which is the reason i contacted you to receive the fund as my partner for investment in your country. The amount is valued at Eu 47,745,533.00 with a financial institution waiting my instruction for further transfer to a destination account as soon as I have your information indicating interest to receive and invest the fund, I will compensate you with 30% of the total amount and you will also get benefit from the investment. If you can handle the fund in a good investment. reply on this email only: reem.alhashimi(a)kakao.com Regards, Ms. Reem Google Forms: Create and analyze surveys.

[PATCH] coresight: remove broken __exit annotations

by Arnd Bergmann

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.
