Merge the timecounter and CPU counter support for the leon3 BSP family.
Remove now unused functions from the CPU counter support of the erc32
and leon3 BSPs.
Update #4954.
Explicitly test the 64-bit integer division and modulo operations. They
are essential for the timekeeping services. On most 32-bit targets,
they need a software implementation.
Update #3716.
Measure the runtime of 1000 no-operation instructions. This may help to
investigate runtime measurement variations which do not result from code
generation or source code changes.
The runtime measurement of a function which does nothing and just
returns gives an estimate of the measurement overhead.
Update #3716.
The <rtems/test-info.h> header file is required for every RTEMS test
program. Move the RTEMS test printer support to a dedicated header file
<rtems/test-printer.h>. This removes an unnecessary dependency to the
RTEMS printer support in <rtems/test-info.h>.
Tests using the RTEMS Testing Framework no longer depend on the
<rtems/printer.h>.
Doing the enabled-by processing just for the ldflags and just for the
link custom commands is confusing. Use an option instead which is
intended to be used for such use cases.
This adds `-u__extendsfdf2` to the `ldflags` for the dl07, dl08, and
dl09 tests to force the inclusion of `__extendsfdf2` in the base image.
This function is part of the GCC software floating point library and is
used in the tests to convert floats to doubles when calling `printf`.
This change requires an rtems-tools update for symbol generation.
Working architectures:
- aarch64
- arm
- powerpc
- sparc
No newlib TLS support but checked:
- i386
- m69k
Updates #4920
The current ARM support in libdebugger does not cover Cortex-M series
cores since it requires support for CP14 system register accessor
instructions. Cortex-M series cores support debug monitor mode, but its
configuration is accessed by memory mapped registers instead of using
CP14. This omits building libdebugger from BSPs that use a cortex-m ABI
flag.
Updates #4924.
The Regulator is an application support class which is used to
deal with the scenario where there is a bursty input source
which needs to be metered out to a destination sink. The maximum
size of bursts needs to be known and the delivery method must
be configured to deliver messages at a rate that allows the
traffic to not overflow.
Define the RTEMS version in the wscript. Optionally use a VERSION file
to change the default values of the wscript. Allow the command line
option --rtems-version to override __RTEMS_MAJOR__. Remove support for
command line configurable options (--rtems-option).
Rename internal define RTEMS_VERSION_VC_KEY to
RTEMS_VERSION_CONTROL_KEY.
The MCP7940M is a I2C RTC chip. The new driver uses the dev/i2c API to
support the RTC. It is written with the intention, that the driver can
be adapted to other RTCs with a similar register layout by just
replacing the initialization function.
The flash configuration is something very board specific. So move the
file to a board specific location. Beneath that, not all controllers and
configurations need the flash config right at the address 0 of the
flash. For example on the i.MXRT11xx, the config has an offset for some
flash types.
This adds support for the STM32H750B-DK discovery kit. This kit includes
a built-in STLINKv3 debugger which provides a USB serial bridge for
USART3. USART1 is routed to the Arduino header and USART2 is routed to
the STMOD connector. This BSP reuses what would otherwise be duplicated
files from the stm32h747i-disco BSP. Note that system_stm32h7xx.c has
been imported from the STM repository with two minor changes wrapped
with #if __rtems__. This hardware has been tested with hello and ticker.
