There is no need to save the thread pointer in _CPU_Context_switch()
since it is a thread invariant. It is initialized once in
_CPU_Context_Initialize().
Enable/disable vector routines now check for a valid vector. Without
these guards, the enable/disable vector routines will not work with the
interrupt server.
The original CPU_COPY() support of Newlib <sys/cpuset.h> had the
parameters in the wrong order. This is fixed in Newlib since
2017-05-22.
Update #3023.
Move RTEMS specifics to <rtems/rtems_bsdnet.h>.
Introduce rtems_tap_ifreq. The interface tap support is RTEMS-specific
and only available in the legacy network stack.
Update #2833.
Remove obsolete support for OFILL, OFDEL, NLDLY, CRDLY, BSDLY, VTDLY,
and FFDLY which is not present on FreeBSD and not implemented in Linux.
Update #2833.
There are mismatched sections in the bootloader input:
ld: Warning: ticker.exe uses hard float, ticker.ralf uses soft float
ld: ticker.exe: compiled normally and linked with modules compiled with -mrelocatable
ld: failed to merge target specific data of file ticker.exe
Suppress this error explicitly.
Set the proper output format in the linker script for the bootloader.
Otherwise the generic linker is used since Binutils 2.28 which does not
understand the PowerPC-specific relocations.
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.
The SYM define concatenates the input with the compiler set
__USER_LABEL_PREFIX__ define. This define appears to be '_' in GCC but
empty in Clang. Therefore when compiling with Clang/LLVM 'SYM(start)'
and 'start' defines the same symbol, and the compiler complains that the
symbol is defined twice.
- All references of %0 changed to %g0
- 'call label,0' changed to 'call label'. According to the sparc
specification call does not take any registers
- '.seg "text"' changed to '.section ".text"'
- the synonym stub is replaced with stb
- the synonym stuh is replaced with sth
The following functions now reports to the user that an overrun has
occured by returning errno EIO:
* grtc_read, on overrun and no more data in the DMA buffer
* ioctl(GRTC_IOC_RECV), on overrun and no more frames in the DMA buffer
* ioctl(GRTC_IOC_ISSTARTED), EIO is returned on overrun
This driver was initially intended for APBUART access on GRLIB PCI
peripherals (AMBA-over-PCI). There are already many APBUART drivers
for LEON. Instead of using this one the termios APBUART should work
on AMBA-over-PCI systems with recent changes on LEON3, however that
has not been tested yet.
