[RFC PATCH] perf cs-etm: Handle valid-but-zero timestamps

by James Clark

There is an intermittent issue on Trogdor devices that results in all Coresight timestamps having a value of zero. Because zero is currently treated as "not found" rather than "found but zero", this breaks the decoding flow when it would otherwise work. This patch adds an out parameter and return code so the difference between zero and non-existent timestamps can be determined. There is also a change to fix an underflow. Although this is a workaround, the change is technically a valid way of writing the cs_etm__etmq_get_timestamp() function. It could have been written similarly to this without trying to work around this issue, so it's no less correct. But, because it's a workaround to a problem elsewhere, I will submit this as an RFC for feedback. This patch applies on top of the "[PATCH v2 0/2] perf cs-etm: Set time on synthesised samples to preserve ordering" patchset.

[PATCH v1 0/3] coresight: Support for building more coresight paths

by Tao Zhang

We are trying to achieve more types of Coresight source devices. For example, we have a type of coresight source devic named TPDM. In the process of using, sometimes mulitiple TPDMs need to be connected to the different input ports on the same funnel. Meanwhile, these TPDMs also need to output from different ports on the funnel. But, at present the Coresight driver assumes a) Only support Coresight source type ETM, ETR and ETF b) Funnels only support mulitiple inputs and one output Which doesn't help to add the above feature for our new Coresight source device TPDM. So, in order to accommodate the new device, we develop the following patches. a) Add support more types of Coresight source devices. b) Add support for multiple output ports on funnel and the output ports could be selected by Corsight source. Applies on coresight/next. http://git.linaro.org/kernel/coresight.git/log/?h=next Tao Zhang (3): coresight: add support to enable more coresight paths coresight: funnel: add support for multiple output ports dt-bindings: arm: add property for selecting funnel output port .../devicetree/bindings/arm/coresight.txt | 5 + drivers/hwtracing/coresight/coresight-core.c | 169 ++++++++++++++------- drivers/hwtracing/coresight/coresight-platform.c | 9 ++ include/linux/coresight.h | 2 + 4 files changed, 127 insertions(+), 58 deletions(-) -- The Qualcomm Innovation Center, Inc. is a member of the Code Aurora Forum, a Linux Foundation Collaborative Project
