cobalt/sched: detect preemptible switch support in pipeline

CONFIG_XENO_ARCH_UNLOCKED_SWITCH is merely an alias for
CONFIG_IPIPE_WANT_PREEMPTIBLE_SWITCH, which is only meaningful to the
ARM architecture, now that PowerPC dropped such support.

Use the pipeline symbol directly to make the dependency explicit.

cobalt/sched: detect preemptible switch support in pipeline

CONFIG_XENO_ARCH_UNLOCKED_SWITCH is merely an alias for
CONFIG_IPIPE_WANT_PREEMPTIBLE_SWITCH, which is only meaningful to the
ARM architecture, now that PowerPC dropped such support.

Use the pipeline symbol directly to make the dependency explicit.

cobalt/sched: detect preemptible switch support in pipeline

CONFIG_XENO_ARCH_UNLOCKED_SWITCH is merely an alias for
CONFIG_IPIPE_WANT_PREEMPTIBLE_SWITCH, which is only meaningful to the
ARM architecture, now that PowerPC dropped such support.

Use the pipeline symbol directly to make the dependency explicit.

cobalt/sched: detect preemptible switch support in pipeline

CONFIG_XENO_ARCH_UNLOCKED_SWITCH is merely an alias for
CONFIG_IPIPE_WANT_PREEMPTIBLE_SWITCH, which is only meaningful to the
ARM architecture, now that PowerPC dropped such support.

Use the pipeline symbol directly to make the dependency explicit.

[Xenomai-git] Philippe Gerum : cobalt/sched: detect preemptible switch support in pipeline

2016-09-22 Thread git repository hosting

cobalt/sched: detect preemptible switch support in pipeline

CONFIG_XENO_ARCH_UNLOCKED_SWITCH is merely an alias for
CONFIG_IPIPE_WANT_PREEMPTIBLE_SWITCH, which is only meaningful to the
ARM architecture, now that PowerPC dropped such support.

Use the pipeline symbol directly to make the dependency explicit.
