Rename _SMP_Get_processor_count() in _SMP_Get_processor_maximum() to be
in line with the API level rtems_scheduler_get_processor_maximum().
Update #3732.
Add rtems_scheduler_get_processor_maximum() as a replacement for
rtems_get_processor_count(). The rtems_get_processor_count() is a bit
orphaned. Adopt it by the Scheduler Manager. The count is also
misleading, since the processor set may have gaps and the actual count
of online processors may be less than the value returned by
rtems_get_processor_count().
Update #3732.
- Use CamelCase as it is not used in our C code. Enables simple search and
replace.
- Prefix with "RTEMS" to aid deployment and integration. It aids
searching and sorting.
Update #3706.
In order to simplify the use of CPU counter values it is beneficial to
have monotonic increasing values within the range of the CPU counter
ticks data type, e.g. 32-bit unsigned integer. This eases the use of
CPU counter timestamps in external tools which do not know the details
of the CPU counter hardware. The CPU counter is the fastest way to get
a time on an RTEMS system.
Such a CPU counter may be also used as the timecounter. Use it on SPARC
for this purpose to simplify the clock drivers.
Update #3456.
The following rtems_cache_*_processor_set() cache manager API functions
are exotic, complex, very hard to use correctly, not used in the RTEMS
code base, and apparently unused by applications.
Close#3622.
The precision clock synthesizer support broke the driver on the QorIQ
P1020. On this device the Alternate Function Register is accessed with
DLAB == 1 instead of the FIFO Control Register (FCR). Restructure the
code to account for this.
Add and use <machine/rtems-bsd-kernel-space.h> and
<machine/rtems-bsd-user-space.h> similar to the libbsd to avoid command
line defines and defines scattered throught the code base.
Simplify cpukit/libnetworking/Makefile.am.
Update #3375.
The genmcf548x partly uses is own implementation of the interrupt
extension API for libbsd support.
This patch is a part of the BSP source reorganization.
Update #3285.
Set the FIFO control register while DLAB == 1 in the line control
register. At least on the QorIQ T4240 the driver still works with the
re-ordered FIFO control register access.
The aim of this clock driver hook was to stop clock tick interrupts at
some late point in the exit() procedure.
The use of atexit() pulls in malloc() which pulls in errno. It is
incompatible with the intention of the
CONFIGURE_DISABLE_NEWLIB_REENTRANCY configuration option.
The exit() function must be called from thread context, so accompanied
clock tick interrupts should cause no harm. On the contrary, someone
may assume a normal operating system operation, e.g. working timeouts.
Remove the Clock_driver_support_shutdown_hardware() clock driver hook.
Close#3436.
Add rtems_counter_frequency() API function. Use it to initialize the
counter value converter via the new system initialization step
(RTEMS_SYSINIT_CPU_COUNTER). This decouples the counter implementation
and the counter converter. It avoids an unnecessary pull in of the
64-bit integer division from libgcc.
Update #3456.
