2020-04-16Canonicalize config.h includeSebastian Huber1-1/+1
Use the following variant which was already used by most source files: #ifdef HAVE_CONFIG_H #include "config.h" #endif
2017-10-12Use right time format in _times()Sebastian Huber1-9/+5
Update #2740. Close #3179.
2017-09-06Fix integer overflow problems in times()Sebastian Huber1-34/+16
An integer overflow may still happen, however, only after 68 years of system uptime. Close #2135.
2016-03-17score: Fix CPU time used by executing threadsSebastian Huber1-15/+11
The CPU time used of a thread was previously maintained per-processor mostly during _Thread_Dispatch(). However, on SMP configurations the actual processor of a thread is difficult to figure out since thread dispatching is a highly asynchronous process (e.g. via inter-processor interrupts). Only the intended processor of a thread is known to the scheduler easily. Do the CPU usage accounting during thread heir updates in the context of the scheduler operations. Provide the function _Thread_Get_CPU_time_used() to get the CPU usage of a thread using proper locks to get a consistent value. Close #2627.
2015-10-26basdefs.h: Add and use RTEMS_UNUSEDSebastian Huber1-1/+1
2015-06-15Remove use ticks for statistics configure option.Joel Sherrill1-38/+30
This was obsolete and broken based upon recent time keeping changes. Thie build option was previously enabled by adding USE_TICKS_FOR_STATISTICS=1 to the configure command line. This propagated into the code as preprocessor conditionals using the __RTEMS_USE_TICKS_FOR_STATISTICS__ conditional.

2012-05-11Remove All CVS Id Strings Possible Using a ScriptJoel Sherrill1-2/+0
Script does what is expected and tries to do it as smartly as possible. + remove occurrences of two blank comment lines next to each other after Id string line removed. + remove entire comment blocks which only exited to contain CVS Ids + If the processing left a blank line at the top of a file, it was removed.

This capability is enabled by default although may be conditionally disabled by the user. It could be too much overhead on small targets but it does not appear to be bad in early testing. Its impact on code size has not been evaluated either. It is possible that both forms of statistics gathering could be disabled with further tweaking of the conditional compilation. * score/src/timespecdividebyinteger.c: New file.

1999-11-17Updated copyright notice.Joel Sherrill1-2/+1
1998-11-23Added base version of file system infrastructure. This includes a majorJoel Sherrill1-12/+24
overhaul of the RTEMS system call interface. This base file system is the "In-Memory File System" aka IMFS. The design and implementation was done by the following people: + Joel Sherrill (joel@OARcorp.com) + Jennifer Averett (jennifer@OARcorp.com) + Steve "Mr Mount" Salitasc (salitasc@OARcorp.com) + Kerwin Wade (wade@OARcorp.com) PROBLEMS ======== + It is VERY likely that merging this will break the UNIX port. This can/will be fixed. + There is likely some reentrancy/mutual exclusion needed. + Eventually, there should be a "mini-IMFS" description table to eliminate links, symlinks, etc to save memory. All you need to have "classic RTEMS" functionality is technically directories and device IO. All the rest could be left out to save memory.
