Rename PER_CPU_WATCHDOG_MONOTONIC to PER_CPU_WATCHDOG_TICKS. Add new
PER_CPU_WATCHDOG_MONOTONIC which is based on the system uptime (measured
by timecounter).

Rename _Thread_queue_Context_set_do_nothing_enqueue_callout() into
_Thread_queue_Context_set_enqueue_do_nothing_extra(). More

Rename _Watchdog_Ticks_from_*() to _Watchdog_Realtime_from_*().
This highlights that these routines are used for the CLOCK_REALTIME
watchdogs (in contrast to CLOCK_MONOTONIC).

Replace STATES_DELAYING with STATES_WAITING_FOR_TIME.
There is no need for separate timeout thread states. The
Thread_Control::Timer::header and Watchdog_Control::cpu members can be
used to figure out the kind of timeout.

Move thread state for _Thread_queue_Enqueue() to the thread queue
context. This reduces the parameter count of _Thread_queue_Enqueue()
from five to four (ARM for example has only four function parameter
registers). Since the thread state is used after several function calls
inside _Thread_queue_Enqueue() this parameter was saved on the stack
previously.
|
|
|
|
|
| |
Delete unused _Thread_queue_Enqueue() and rename
_Thread_queue_Enqueue_critical() to _Thread_queue_Enqueue().
|
|
|
|
|
|
|
| |
Replace the expected thread dispatch disable level with a thread queue
enqueue callout. This enables the use of _Thread_Dispatch_direct() in
the thread queue enqueue procedure. This avoids impossible exection
paths, e.g. Per_CPU_Control::dispatch_necessary is always true.
|
|
|
|

|

This function is useful for operations which synchronously block, e.g.
self restart, self deletion, yield, sleep. It helps to detect if these
operations are called in the wrong context. Since the thread dispatch
necessary indicator is not used, this is more robust in some SMP
situations.

* Fixes a bug with elapsed time calculations misusing absolute time
arguments in nanosleep_helper by passing the requested relative interval.
* Fixes a bug with truncation of absolute timeouts by passing the
full 64-bit value to Thread_queue_Enqueue.
* Share yield logic between nanosleep and clock_nanosleep.

Sleeping with CLOCK_REALTIME should use the WATCHDOG_ABSOLUTE
clock discipline for the threadq so that the timeout interval
may change in case the clock source changes. Similarly,
CLOCK_MONOTONIC uses the WATCHDOG_RELATIVE threadq that will
only wakeup the thread after the requested count of ticks elapse.

Clock disciplines may be WATCHDOG_RELATIVE, WATCHDOG_ABSOLUTE,
or WATCHDOG_NO_TIMEOUT. A discipline of WATCHDOG_RELATIVE with
a timeout of WATCHDOG_NO_TIMEOUT is equivalent to a discipline
of WATCHDOG_NO_TIMEOUT.

Move the safety check performed by
_CORE_mutex_Check_dispatch_for_seize() out of the performance critical
path and generalize it. Blocking on a thread queue with an unexpected
thread dispatch disabled level is illegal in all system states.
Add the expected thread dispatch disable level (which may be 1 or 2
depending on the operation) to Thread_queue_Context and use it in
_Thread_queue_Enqueue_critical().
|
|
|
|
|
|
|
|
|
|
|
| |
Unify the status codes of the Classic and POSIX API to use the new enum
Status_Control. This eliminates the Thread_Control::Wait::timeout_code
field and the timeout parameter of _Thread_queue_Enqueue_critical() and
_MPCI_Send_request_packet(). It gets rid of the status code translation
tables and instead uses simple bit operations to get the status for a
particular API. This enables translation of status code constants at
compile time. Add _Thread_Wait_get_status() to avoid direct access of
thread internal data structures.
|
|
|
|
|
|
|
|
|
| |
Remove the Thread_queue_Queue::operations field to reduce the size of
this structure. Add a thread queue operations parameter to the
_Thread_queue_First(), _Thread_queue_First_locked(),
_Thread_queue_Enqueue(), _Thread_queue_Dequeue() and
_Thread_queue_Flush() functions. This is a preparation patch to reduce
the size of several synchronization objects.

This resulted in the elapsed time going below 0 and an arbitrarily large
number returned as the time remaining.

Suppose we have two tasks A and B and two processors. Task A is about
to delete task B. Now task B calls rtems_task_wake_after(1) on the
other processor. Task B will block on the Giant lock. Task A
progresses with the task B deletion until it has to wait for
termination. Now task B obtains the Giant lock, sets its state to
STATES_DELAYING, initializes its watchdog timer and waits. Eventually
_Thread_Delay_ended() is called, but now _Thread_Get() returned NULL
since the thread is already marked as deleted. Thus task B remained
forever in the STATES_DELAYING state.
Instead of passing the thread identifier use the thread control block
directly via the watchdog user argument. This makes
_Thread_Delay_ended() also a bit more efficient.

The _Scheduler_Yield() was called by the executing thread with thread
dispatching disabled and interrupts enabled. The rtems_task_suspend()
is explicitly allowed in ISRs:
http://rtems.org/onlinedocs/doc-current/share/rtems/html/c_user/Interrupt-Manager-Directives-Allowed-from-an-ISR.html#Interrupt-Manager-Directives-Allowed-from-an-ISR
Unlike the other scheduler operations the locking was performed inside
the operation. This lead to the following race condition. Suppose a
ISR suspends the executing thread right before the yield scheduler
operation. Now the executing thread is not longer in the set of ready
threads. The typical scheduler operations did not check the thread
state and will now extract the thread again and enqueue it. This
corrupted data structures.
Add _Thread_Yield() and do the scheduler yield operation with interrupts
disabled. This has a negligible effect on the interrupt latency.
|
|
|
|
|
| |
Scheduler operations must be free of a global scheduler context to
enable partitioned/clustered scheduling.

TOD_MILLISECONDS_TO_TICKS().

Move implementation specific parts of thread.h and thread.inl into new
header file threadimpl.h. The thread.h contains now only the
application visible API.
Remove superfluous header file includes from various files.

Move implementation specific parts of watchdog.h and watchdog.inl into
new header file watchdogimpl.h. The watchdog.h contains now only the
application visible API.
|
|
|
|
|
|
| |
The yielding thread of the yield operation is now specified by a
parameter. The tick operation may be performed for each executing
thread in a SMP configuration.

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.
