We must not clear the priority updates in _Thread_queue_Extract_locked()
since this function is used by the priority ceiling surrender operations
after the ceiling priority handover from the previous owner to the new
owner. This is especially important in SMP configurations.
Move the _Thread_queue_Context_clear_priority_updates() invocation to
the callers.
Close#3237.
The thread queue extract operations performed by the
_Thread_queue_Flush_critical() may result in a priority change of the
thread queue owner. Carry out the scheduler priority update operation.
This is especially important in SMP configurations.
Close#3236.
The _Semaphore_Get_operations() must return the proper operations for
priority inheritance semaphores.
Add a test case for rtems_semaphore_flush() with priority inheritance.
Close#3235.
The watchdog routines invoked by the timer server may use mutexes for
synchronization. Ensure that the resource count of the timer server is
zero after each watchdog routine invocation. This helps to detect
broken watchdog routines.
The link time wrap of printf leads to unresolved symbols in the loadable
modules. This resulted in infinite loops and test timeouts. Use
rtems_printf() for output.
Update #3199.
SMP safe by spin-lock protection and semaphore. On spin-lock per SpW/AMBA
port to allow multiple parallel register operations per port. A common
semaphore for general SpW router configuration such as routing table.
Move to a C API instead of using the I/O Manager. The SpW router driver
does not perform any I/O only management of the router.
Update #2355.
- Remove the macro defines and the need for tmacro.h by remapping the
symbols using ld's wrap option.
- Remove FLUSH_OUTPUT, it was empty.
- Move rtems_test_exit to libmisc/testsupport as a function.
Update #3199.
Provide functions to get the version string, major, minor and revision
numbers and the version control identifer that is a unique tag for
the version control system.
Update #3199.
Remove POSIX_API_Control::created_with_explicit_scheduler. Add
Thread_Control::was_created_with_inherited_scheduler. This fixes also
pthread_getattr_np() for Classic tasks.
Update #2514.
In canonical mode, input is made available line by line. We must stop
the canonical buffer filling upon reception of an end-of-line character.
Close#3218.
Change the chain order relation to use a directly specified left hand
side value. This is similar to _RBTree_Insert_inline() and helps the
compiler to better optimize the code.
The previous vprintk() implementation had a questionable licence header,
lacks support for the 'z' and 'j' format specifiers, is not robust
against invalid format specifiers, uses a global variable for output.
Replace it with a stripped down version of the FreeBSD kernel kvprintf()
function.
The new implementation allows a low overhead rtems_snprintf() if
necessary.
Update #3199.
Close#3216.
