Martin Stein 181c78d482 timeout: use uint64_t for all plain time values This enforces the use of unsigned 64-bit values for time in the duration type, the timeout framework, the timer session, the userland timer-drivers, and the alarm framework on all platforms. The commit also adapts the code that uses these tools accross all basic repositories (base, base-, os. gems, libports, ports, dde_) to use unsigned 64-bit values for time as well as far as this does not imply profound modifications.

README

This component obtains the information about the existing trace subjects from
core's "TRACE" service and shows via the LOG session the highest CPU consumer
per CPU in percentage.

Configuration
-------------

The interval of output generation can be defined via the 'period_ms' attribute
of the '<config>' node. The value is specified in milliseconds.
The threads with the top most execution time are shown per CPU. The sorting
of the execution time can be shown per thread ('ec' - execution context) or,
if supported by the kernel, per scheduling context of a thread ('sc').

The following example shows the default values.

! <config period_ms="5000" sort_time="ec"/>
