tools/thermal: Fix possible path truncations

2022-08-03T17:28:46+00:00

A build with -D_FORTIFY_SOURCE=2 enabled will produce the following warnings: sysfs.c:63:30: warning: '%s' directive output may be truncated writing up to 255 bytes into a region of size between 0 and 255 [-Wformat-truncation=] snprintf(filepath, 256, "%s/%s", path, filename); ^~ Bump up the buffer to PATH_MAX which is the limit and account for all of the possible NUL and separators that could lead to exceeding the allocated buffer sizes.

thermal/tools/tmon: Include pthread and time headers in tmon.h

2022-07-28T15:29:51+00:00

Include sys/time.h and pthread.h in tmon.h, so that types "pthread_mutex_t" and "struct timeval tv" are known when tmon.h references them. Without these headers, compiling tmon against musl-libc will fail with these errors: In file included from sysfs.c:31:0: tmon.h:47:8: error: unknown type name 'pthread_mutex_t' extern pthread_mutex_t input_lock; ^~~~~~~~~~~~~~~ make[3]: *** [: sysfs.o] Error 1 make[3]: *** Waiting for unfinished jobs....

tools/thermal: Add thermal daemon skeleton

2022-05-19T10:11:52+00:00

This change provides a simple daemon skeleton. It is an example of how to use the thermal library which wraps all the complex code related to the netlink and transforms it into a callback oriented code. The goal of this skeleton is to give a base brick for anyone interested in writing its own thermal engine or as an example to rely on to write its own thermal monitoring implementation. In the future, it will evolve with more features and hopefully more logic.

tools/thermal: Add a temperature capture tool

2022-05-19T10:11:52+00:00

The 'thermometer' tool allows to capture the temperature of a set of thermal zones defined in a configuration file at a specified rate. It is designed to have the lowest possible overhead. It will write the captured temperature per thermal zone per file so making easier to write a gnuplot script.
