This change adds rtems_printf and related functions and wraps the RTEMS print plugin support into a user API. All references to the plugin are removed and replaced with the rtems_printer interface. Printk and related functions are made to return a valid number of characters formatted and output. The function attribute to check printf functions has been added to rtems_printf and printk. No changes to remove warrnings are part of this patch set. The testsuite has been moved over to the rtems_printer. The testsuite has a mix of rtems_printer access and direct print control via the tmacros.h header file. The support for begink/endk has been removed as it served no purpose and only confused the code base. The testsuite has not been refactored to use rtems_printf. This is future work.
This directory contains code to report and reset per-task CPU usage.
If the BSP supports nanosecond timestamp granularity, this this information
is very accurate. Otherwise, it is dependendent on the tick granularity.
It provides two primary features:
+ Generate a CPU Usage Report
+ Reset CPU Usage Information
NOTES:
1. If configured for tick granularity, CPU usage is "docked" by a
clock tick at each context switch.
2. If configured for nanosecond granularity, no work is done at each
clock tick. All bookkeeping is done as part of a context switch.
