[PATCH] score: Add _IO_Relax()

This function may be used to burn a couple of processor cycles with minimum impact on the system bus. It may be used in busy wait loops. Since it is a global function, it is possible to wrap it in device driver test code. --- cpukit/include/rtems/score/io.h | 8 + cpukit/score/src/iorelax.

[PATCH 2/4] bsp/leon3: Use interrupt entry for the SMP support

Using rtems_interrupt_entry_install() instead of rtems_interrupt_handler_install() avoids a dependency on the dynamic memory allocation. --- bsps/sparc/leon3/start/bspsmp.c | 13 + 1 file changed, 9 insertions(+), 4 deletions(-) diff --git a/bsps/sparc/leon3/start/bspsmp.c b/bsps/spar

[PATCH 1/4] bsp/leon3: Use interrupt entry for Clock Driver

Using rtems_interrupt_entry_install() instead of rtems_interrupt_handler_install() avoids a dependency on the dynamic memory allocation. --- bsps/sparc/leon3/clock/ckinit.c | 14 ++ 1 file changed, 10 insertions(+), 4 deletions(-) diff --git a/bsps/sparc/leon3/clock/ckinit.c b/bsps/sp

[PATCH 3/4] bsp/leon3: Use interrupt entry for tm27 support

Using rtems_interrupt_entry_install() instead of rtems_interrupt_handler_install() avoids a dependency on the dynamic memory allocation. Use Interrupt Manager directives instead of a BSP-specific API. Use inline functions. In SMP configurations, set an affinity to all online processors and raise

[PATCH 4/4] bsp/leon3: Do not invalidate cache in SMP start

Since the trap table is now statically initialized, there is no need to invalidate the instruction cache. --- bsps/sparc/leon3/start/bspsmp.c | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) diff --git a/bsps/sparc/leon3/start/bspsmp.c b/bsps/sparc/leon3/start/bspsmp.c index 74f9df5404..acd9

[PATCH] bsps/aarch64: Remove erroneous cache feature

The AArch64 cache implementation does not define rtems_cache_disable_data(), but declares that it does via CPU_CACHE_SUPPORT_PROVIDES_DISABLE_DATA. The existing implementation of _CPU_cache_disable_data() is sufficient to enable this functionality without the erroneous cache feature flag. Closes #
