2015-10-10tools/thermal: tmon: use pkg-config also for CFLAGSOlaf Hering1-0/+3
The header <panel.h> might be in /usr/include/ncursesw, which is not part of the standard include path. This fixes compile on openSUSE. Signed-off-by: Olaf Hering <olaf@aepfle.de> Signed-off-by: Zhang Rui <rui.zhang@intel.com>

2015-02-28tools/thermal: tmon: silence 'set but not used' warningsBrian Norris1-0/+3
gcc complains about the 'cols' variable being unused. This is unavoidable, given the ncurses getmaxyx() macro-based API, which wants to assign to a variable directly, even when we're not going to use it. Warning: gcc -O1 -Wall -Wshadow -W -Wformat -Wimplicit-function-declaration -Wimplicit-int -fstack-protector -D VERSION=\"1.0\" -c -o tui.o tui.c tui.c: In function ‘show_dialogue’: tui.c:288:12: warning: variable ‘cols’ set but not used [-Wunused-but-set-variable] int rows, cols; ^ So, add a hack to get rid of that warning.

2015-02-28tools/thermal: tmon: use pkg-config to determine library dependenciesBrian Norris1-1/+10
Some distros (e.g., Arch Linux) don't package the tinfo library separately from ncurses, so don't unconditionally include it. Instead, use pkg-config. The $(STATIC) ugliness is to handle the reported build case from commit 6b533269fb25 ("tools/thermal: tmon: fix compilation errors when building statically"), where a developer wants to be able to build with: make LDFLAGS=-static which requires an additional pkg-config flag. Finally, support a lowest common denominator fallback (-lpanel -lncurses) for build systems that don't have pkg-config entries for ncurses.

2015-02-28tools/thermal: tmon: fixup tui windowing calculationsBrian Norris1-5/+16
The number of rows in the dialog vary according to the number of cooling devices. However, some of the windowing computations were assuming a fixed number of rows. This computation is OK when we have between 4 and 9 cooling devices (and they wrap to the next column), but with fewer devices, we end up printing off the end of the window. This unifies the row computation into a single function and uses that throughout the TUI code. This also accounts for increasing the number of rows when there are more than 9 total cooling devices.

2015-02-28tools/thermal: tmon: add --target-temp parameterBrian Norris2-2/+14
If we launch in daemon mode (--daemon), we don't have the ncurses UI, but we might want to set the target temperature still. For example, someone might stick the following in their boot script: tmon --control intel_powerclamp --target-temp 90 --log --daemon This would turn on CPU idle injection when we're around 90 degrees celsius, and would log temperature and throttling info to /var/tmp/tmon.log.

2014-07-01tmon: Check log file for common secuirty issuesNeil Horman1-0/+24
The tmon logging system blindly opens its log file on a static path, making it very easy for someone to redirect that log information to inappropriate places or overwrite other users data. Do some easy checking to make sure we're not logging to a symlink or a file owned by another user.

2013-11-07tools/thermal: Introduce tmon, a tool for thermal subsystemJacob Pan8-0/+2160
Increasingly, Linux is running on thermally constrained devices. The simple thermal relationship between processor and fan has become past for modern computers. As hardware vendors cope with the thermal constraints on their products, more sensors are added, new cooling capabilities are introduced. The complexity of the thermal relationship can grow exponentially among cooling devices, zones, sensors, and trip points. They can also change dynamically. To expose such relationship to the userspace, Linux generic thermal layer introduced sysfs entry at /sys/class/thermal with a matrix of symbolic links, trip point bindings, and device instances. To traverse such matrix by hand is not a trivial task. Testing is also difficult in that thermal conditions are often exception cases that hard to reach in normal operations. TMON is conceived as a tool to help visualize, tune, and test the complex thermal subsystem. Signed-off-by: Jacob Pan <jacob.jun.pan@linux.intel.com> Signed-off-by: Zhang Rui <rui.zhang@intel.com>
