Updates #3000.

This header file contained timing overhead values which are hard to
maintain.

|
|
The TEST_EXTERN is a used only by the system.h style tests and they use
CONFIGURE_INIT appropriately.

Reduce test context size in non-SMP configurations.
Close #3200.

- Remove the printf support leaving the direct printk support configured
with TESTS_USE_PRINTK and all other output goes via a buffered vsniprintf
call to printk.
- Control the test's single init for functions and global data with
TEST_INIT and not CONFIGURE_INIT. They are now separate.
Updates #3170.

It is getting harder to prevent the compiler from optimizing away the
recursive function calls.

Do not use the processor count to determine if SMP is enabled. Instead
use a dedicated configuration option. Enable SMP by default in SMP
configurations.
Add CONFIGURE_DISABLE_SMP_CONFIGURATION to all test which would fail
otherwise.
Update #3001.
|
|
Enable the SMP configuration by default in case SMP is enabled. Add
configuration option CONFIGURE_DISABLE_SMP_CONFIGURATION to disable it
explicitly.
Add CONFIGURE_DISABLE_SMP_CONFIGURATION to all test which would fail
otherwise.
Update #3001.

errors.
- Add a top level test configuration file for test states that are common
to all BSPs. This saves adding a test configuration (tcfg) file for
every BSP.
- Add the test states 'user-input' and 'benchmark'. This
lets 'rtems-test' stop the test rather than waiting for a timeout or
letting a benchmark run without the user asking for it to run.
- Implement rtems-test-check in Python to make it faster. The shell script
had grown to a point it was noticably slowing the build down.
- Fix the configure.ac and Makefile.am files for a number of the
test directories. The files are difficiult to keep in sync with the
number of tests and mistakes can happen such as tests being left
out of the build. The test fsrofs01 is an example. Also a there was
a mix of SUBDIRS and _SUBDIRS being used and only _SUBDIRS should be
used.
- Fix the test fsrofs01 so it compiles.
Closes #2963.

Rename CONFIGURE_SMP_MAXIMUM_PROCESSORS to CONFIGURE_MAXIMUM_PROCESSORS
since the SMP part is superfluous.
Update #2894.
|
|
Enable the SMP support if CONFIGURE_SMP_MAXIMUM_PROCESSORS > 1.
Update #2893.
|
|
Add _CPU_Get_current_per_CPU_control() on SMP configurations. Use SPRG0
for the current per-CPU control. This reduces the code size by three
instructions and is slightly faster.
Update #2805.

The SMP ticket lock release turned out to be suitable for inlining, e.g.
a hand full of instructions, no branches.
The changes in the screen files do not reflect the changes due to this
commit. However, they are now up to date. Obtained on a T4240 running
at 1.5GHz using GCC 7.0.0 20161108..

Binary semaphores (not simple binary semaphores) maintain the resource
count since 8797c76addf22a2f0ffc3717ff977695e35b9b0b. Do this also for
initially locked binary semaphores.
|
|
Add plot script.

Replace Thread_Scheduler_control::control and
Thread_Scheduler_control::own_control with new
Thread_Scheduler_control::home.
Update #2556.
|
|
This demonstrates the effect of false cache line sharing in case of
Classic mutexes.
|
|
Introduce Thread_queue_Lock_context to contain the context necessary for
thread queue lock and thread wait lock acquire/release operations to
reduce the Thread_Control size.
|
|
Add _Thread_queue_Context_set_MP_callout() to simplify
_Thread_queue_Context_initialize(). This makes it possible to more
easily add additional fields to Thread_queue_Context.
|
|
Drop the multiprocessing (MP) dependent callout parameter from the
thread queue extract, dequeue, flush and unblock methods. Merge this
parameter with the lock context into new structure Thread_queue_Context.
This helps to gets rid of the conditionally compiled method call
helpers.
|
|
Uniformly use *_Get() to get an object by identifier with a lock
context.
|
|
Use _Objects_Get_local() for _Semaphore_Get_interrupt_disable() to get
rid of the location parameter. Move remote object handling to semaphore
MPCI support.

This is a preparation to remove the Giant lock.
Update #2555.

Rename _ISR_Disable() into _ISR_Local_disable(). Rename _ISR_Enable()
into _ISR_Local_enable(). Remove _Debug_Is_owner_of_giant().
This is a preparation to remove the Giant lock.
Update #2555.
|
|
Rename _ISR_Disable_without_giant() into _ISR_Local_disable(). Rename
_ISR_Enable_without_giant() into _ISR_Local_enable().
This is a preparation to remove the Giant lock.
Update #2555.

|
Replace _Thread_Disable_dispatch() with _Thread_Dispatch_disable().
Replace _Thread_Enable_dispatch() with _Thread_Dispatch_enable().
This is a preparation to remove the Giant lock.
Update #2555.

Replace _Thread_Get() with _Thread_Get_interrupt_disable() to avoid the
Giant lock.

In addition protect scheduler of thread by thread state lock. Enables
use of scheduler per-instance locks.

This service was marked as deprecated long prior to the 4.11 release
series and is now being removed.

Test run performed on T4240 running at 1667MHz in uni-processor
configuration.

Notepads where a feature of RTEMS' tasks that simply functioned in
the same way as POSIX keys or threaded local storage (TLS). They were
introduced well before per task variables, which are also deprecated,
and were barely used in favor of their POSIX alternatives.
In addition to their scarce usage, Notepads took up unnecessary memory.
For each task:
- 16 32-bit integers were allocated.
- A total of 64 bytes per task per thread.
This is especially critical in low memory and safety-critical applications.
They are also defined as uint32_t, and therefore are not guaranteed to
hold a pointer.
Lastly, they are not portable solutions for SMP and uniprocessor systems,
like POSIX keys and TLS.
updates #2493.

This define accidentally re-appeared.
|
|
Add rtems_interrupt_local_disable|enable() as suggested by Pavel Pisa to
emphasize that interrupts are only disabled on the current processor.
Do not define the rtems_interrupt_disable|enable|flash() macros and
functions on SMP configurations since they don't ensure system wide
mutual exclusion.

It is wrong to restore the floating point context here. The
_Context_Switch() ends up in _Thread_Handler() which will call
_Thread_Restore_fp(). In _Thread_Do_dispatch() the FP restore is after
the context switch.
|
|
There is no NULL pointer access. Please note that
_Thread_Get_executing() != executing variable in Low_task().
This reverts commit 5611839a7e2e371dd1f327c336c785095f634e55.

These tests intentionally use the deprecated method. Eventually
this code in the sections can be deleted.
|
|
Add rtems_test_parallel_get_task_id().

Deprecate Classic API Notepads. Mark task_set/get_note() with
the deprecated attribute, and also mark the notepads field.
Replace disable with enable option for notepads in confdefs.h,
and make notepads disabled by default. The previous option
CONFIGURE_DISABLE_CLASSIC_API_NOTEPADS is now unused and
will emit a compile-time warning. A new option
CONFIGURE_ENABLE_CLASSIC_API_NOTEPADS is available to turn
on notepads, but it also will emit a compile-time warning
to indicate that notepads are deprecated.
Closes #2265
