Check the interrupt stacks of all processors. Set up the interrupt
stack of the current processor for high water testing in the thread
begin extension. This must be done after multi-threading started, since
the initialization stacks may reuse the interrupt stacks. Disable
thread dispatching in SMP configurations to prevent thread migration.
Writing to the interrupt stack is only safe if done from the
corresponding processor in thread context.
Update #3459.
Use the standard ARMv7-M systick module for the ARMv7-M CPU counter
instead of DWT counter since the DWT counter is affected by power saving
states.
Use an inline function for _CPU_Counter_difference() for all ARM BSPs.
Update #3456.
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.
The last installed tool in RTEMS repository is the install-if-change
script. It is not used to build/install BSPs. This script does the
same as the standard "install" program with an additional feature to
install variants via the -V command line option.
This script is used by the standard Makefile support:
c/src/make/host.cfg.in:INSTALL_CHANGE=$(PROJECT_BIN)/install-if-change
The INSTALL_CHANGE is used by:
c/src/make/host.cfg.in:ifndef INSTALL_CHANGE
c/src/make/host.cfg.in:INSTALL_CHANGE=$(PROJECT_BIN)/install-if-change
c/src/make/host.cfg.in:INSTALL_VARIANT=$(INSTALL_CHANGE) -V
"$(LIB_VARIANT)"
Remove the support for variant installation and instead use the standard
"install" program. This breaks application Makefiles using the standard
Makefile support of RTEMS.
Close#3455.
All tools should be removed from the RTEMS source repository at some
point in time. Tools with a BSD-style license will be moved to the
RTEMS tools repository. Unfortunately, this tool has no license
information.
Remove all uses of this tool from the code base. Users of HEX files
should consider to use ELF instead.
Close#3379.
This program has no license information and is unused in the RTEMS
build. Users of HEX files should consider to use ELF instead. Remove
it.
Close#3378.
This program has no license information and is unused in the RTEMS
build. General usability is questionable, for example a
sed -i 's/[[:space:]]*$//' file
performs a similar task. Remove it.
Close#3377.
This program has no license information and is unused in the RTEMS
build. General usability is questionable, for example a
awk 'length($0) > 80' < file
performs a similar task. Remove it.
Close#3376.
All tools should be removed from the RTEMS source repository at some
point in time. Tools with a BSD-style license will be moved to the
RTEMS tools repository. Unfortunately, the this tool is RTEMS GPL
licensed.
If users of this tool still exist, they can reimplement the
functionality using a BSD-style license and add it to the RTEMS tools.
Close#3444.
All tools should be removed from the RTEMS source repository at some
point in time. Tools with a BSD-style license will be moved to the RTEMS
tools repository. Unfortunately, the shgen tool is GPL licensed.
Remove all uses of this tool from the code base. Replace generated files
with stub functions. If users of this BSP still exist, they can
reimplement the functionality using a BSD-style license.
Close#3443.
The ppc405 define must be checked before the ppc403 define. The ppc405
define is provided by <bspopts.h>. The ppc403 define is provided by GCC
as a built-in define if no ppc* or mpc* define is set via the
command line (see GCC sources "gcc/config/rs6000/rtems.h").
Update #3425.
An invalid heap usage such as a double free is usually a fatal error
since this indicates a use after free. Replace the use of printk() in
free() with a fatal error.
Update #3437.
Move _Status_Object_name_errors_to_status to a separate file to avoid a
dependency on errno. Dependencies to errno are hard to be removed by
the linker garbage collection.
_Timespec_Equal_to() does not set errno, hence avoid using perror(),
instead use fprintf() to stderr, and extend the error message to provide
information about what the error is (measured timer value after
re-arming is not equal to the configured interval), and how large of a
difference was measured.

Quite a number of GMAC_... functions had a side effect of enabling the
transmit and receive. During the initialization of the ethernet driver,
that lead to the situation that the receive has been already enabled
while the DMA isn't set up correctly. Therefore the DMA interpreted the
values at address 0 as an DMA descriptor. When a packet is received
during that time, the behaviour is quite undefined.
The d542af2e43 commit was a bad one.
The riscv32 and riscv64 targets share a riscv source directory. The
potential future powerpcspe and powerpc targets need this change as
well.
For example ${target_arch} is "riscv32" and ${cfg_arch} is "riscv".
This allows a user to overwrite some MPU settings. That can for example
be usefull for devices with special requirements that are connected to
the external bus interface.
