The once massive overhead imposed on the MMU context switching code for invalidating the cache is long gone with VIPT indexing, and keeping IRQs off while switching the memory context on armv8 these days is not an issue. Actually, the complexity of the code involved in dealing with unlocked switching may overbalance the expected gain. However, the mainline kernel implementation for ASID management in the SMP case currently requires us to keep IRQs enabled when allocating a new MM context over the Xenomai domain, just like it did for aarch32 during the 2.6.3x time frame until the IPI-based approach was eventually dropped. So, let's restrict unlocked switching to the SMP case, forcing it off otherwise, in the hope we can drop it entirely in the future. At this chance, CONFIG_IPIPE_WANT_PREEMPTIBLE_SWITCH moves to the kernel area, where it actually belongs. --- kernel/cobalt/arch/arm64/Kconfig | 21 + 1 file changed, 1 insertion(+), 20 deletions(-) diff --git a/kernel/cobalt/arch/arm64/Kconfig b/kernel/cobalt/arch/arm64/Kconfig index dc6485d..927c647 100644 --- a/kernel/cobalt/arch/arm64/Kconfig +++ b/kernel/cobalt/arch/arm64/Kconfig @@ -1,27 +1,8 @@ source "kernel/xenomai/Kconfig" source "drivers/xenomai/Kconfig" -menu "Machine/platform-specific options" - config XENO_ARCH_UNLOCKED_SWITCH - bool "Unlocked context switch" - default y - help - The Cobalt core may allow non-atomic execution of the - machine-dependent context switching code, so that other CPUs - and/or local interrupts may execute concurrently. - - This option reduces interrupt latency when costly cache and - TLB flushes are required to switch context. - - You definitely want to enable that option on low-end ARM - platforms. -endmenu - -config IPIPE_WANT_PREEMPTIBLE_SWITCH - bool - default y if XENO_ARCH_UNLOCKED_SWITCH - default n if !XENO_ARCH_UNLOCKED_SWITCH + def_bool IPIPE_WANT_PREEMPTIBLE_SWITCH config IPIPE_WANT_ACTIVE_MM def_bool y ___ Xenomai-git mailing list Xenomai-git@xenomai.org https://xenomai.org/mailman/listinfo/xenomai-git

The result would be runtime ld.so errors for the binaries or linking problems with the .so. gcc defaults to "--no-as-needed" that is why we never needed to specify that flag explicitly. But gcc from Ubuntu is patched to default to "--as-needed". This patch enforces "--no-as-needed", which will have no effect on most toolchains.
