These are available only on some hardware such as Intel +Sandybridge and newer, and cover only part of the machine's components such as +CPU, DRAM, and graphics. However, they provide accurate and immediate readings +and don't require a battery at all. + +The output is like @command{vmstat} but also shows power consumption statistics: +at the end of a run, @command{powerstat} will calculate the average, standard +deviation, and minimum and maximum values. It can show a nice histogram too.") + (license license:gpl2))) + (define-public psmisc (package (name "psmisc") |
