There are two reasons to do this, firstly there is a shellcheck warning in cs_etm_dev_name(), which can be completely deleted. And secondly the current iteration method doesn't support systems with both ETE and ETM because it picks one or the other. There isn't a known system with this configuration, but it could happen in the future. Iterating over all the sources for each CPU can be done by going through /sys/bus/event_source/devices/cs_etm/cpu* and following the symlink back to the Coresight device in /sys/bus/coresight/devices. This will work whether the device is ETE, ETM or any future name, and is much simpler and doesn't require any hard coded version numbers Suggested-by: Suzuki K Poulose <suzuki.poulose@arm.com> Signed-off-by: James Clark <james.clark@arm.com> Acked-by: Ian Rogers <irogers@google.com> Tested-by: Leo Yan <leo.yan@linaro.org> Cc: tianruidong@linux.alibaba.com Cc: Kajol Jain <kjain@linux.ibm.com> Cc: Anushree Mathur <anushree.mathur@linux.vnet.ibm.com> Cc: Tiezhu Yang <yangtiezhu@loongson.cn> Cc: atrajeev@linux.vnet.ibm.com Cc: coresight@lists.linaro.org Link: https://lore.kernel.org/r/20231023131550.487760-1-james.clark@arm.com Signed-off-by: Namhyung Kim <namhyung@kernel.org> |
