Linux kernel source tree

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> |

Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
