Add the ability to view response codes as well. I dropped the EVENT_CLASS since there is only one event per class. cros_ec_cmd has now been renamed to cros_ec_request_start. Example: $ echo 1 > /sys/kernel/debug/tracing/events/cros_ec/enable $ cat /sys/kernel/debug/tracing/trace 369.416372: cros_ec_request_start: version: 0, command: EC_CMD_USB_PD_POWER_INFO 369.420528: cros_ec_request_done: version: 0, command: EC_CMD_USB_PD_POWER_INFO, ec result: EC_RES_SUCCESS, retval: 16 369.420529: cros_ec_request_start: version: 0, command: EC_CMD_USB_PD_DISCOVERY 369.421383: cros_ec_request_done: version: 0, command: EC_CMD_USB_PD_DISCOVERY, ec result: EC_RES_SUCCESS, retval: 5 Signed-off-by: Raul E Rangel <rrangel@chromium.org> Signed-off-by: Enric Balletbo i Serra <enric.balletbo@collabora.com> |

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.
