Do not supsend self while waiting for termination since the
rtems_task_delete() may take place while the rtems_task_suspend() waits
for the Giant lock preventing delivery of the inter-processor interrupt.
The result is a suspended and terminated thread (this is a valid state,
but leads in this case to a test failure).
Add AltiVec and FPU support to the Context_Control in case we use the
e6500 multilib.
Add PPC_MULTILIB_ALTIVEC and PPC_MULTILIB_FPU multilib defines. Add
non-volatile AltiVec and FPU context to Context_Control. Add save/restore of
non-volatile AltiVec and FPU to _CPU_Context_switch(). Add save/restore
of volatile AltiVec and FPU context to the exception code. Adjust data
cache optimizations for the new context and cache line size.
The Coverity issue was an ignored return value from a read()
in a loop which should have been a seek() since the data
read was ignored.
The file itself needed reformatting to conform to RTEMS style.
This allows the BSP to define an optional spin delay which is
useful for making time appear to pass at a rate closer to
wall time. On the Edison, this was used with a polled console
driver to slow polling to a reasonable rate and make time
pass reasonably close to correctly even with no clock tick
support.
This allows the support for the legacy COM1-COM4 serial ports
to be completely disabled. It is needed to prevent hangs on some
hardware. In particular, the Intel Edison where it is not present.
This allows the IDE support to be completely disabled. It is needed to
prevent hangs on some hardware. In particular, the Intel Edison where
it is not present.
This allows the VGA and keyboard console to be completely disabled.
It is useful on PCs without displays and prevents a very slow boot
time on the Intel Edison.
The current algorithm scans all PCI busses (0..ff)
and all devices (0..31) on each bus for bridges
and determines the maximum of all subordinate
busses encountered.
However, the algorithm does not scan all functions
present in multi-function devices -- I have a PCI express
root complex (82801H) where multiple (non-zero index)
functions are 'PCI bridges' whose subordinate bus number is
missed by the original algorithm.
This commit makes sure that the scan
is extended to all functions of multi-function
devices.
See #2067
rtems_dhcp_failsafe() can be configured at compile time with
various options. This change makes it possible to instead configure
it at runtime.
This will make it marginally larger. I haven't measured the difference
but I'll guess it's in the lower hundreds of bytes. The change could be
modified to leave it either compile time or run time configurable,
I prefer the simplicity of a single method.
