Discussion of a RISC-V change revealed that for PPC and RISC-V we don't really set any default, but rather rely on internals of kconfig picking the lowest of the permitted values in such a case. Let's make this explicit, requiring architectures that mean to permit SMP by default to explicitly record some sensible value here.
Leverage the adjustment to the "1" case to simplify all subsequent ones. Signed-off-by: Jan Beulich <[email protected]> --- For not-yet-SMP-capable ports we might go even further and use range 1 1 if !X86 && (!ARM || MPU) at the top. Thoughts? (I've not done this right away as it is liable to get unwieldy when we have a larger number of SMP-capable ports.) --- a/xen/arch/Kconfig +++ b/xen/arch/Kconfig @@ -9,11 +9,11 @@ config NR_CPUS range 1 1 if ARM && MPU range 1 16383 default "256" if X86 - default "1" if ARM && MPU - default "8" if ARM && RCAR3 - default "4" if ARM && QEMU - default "4" if ARM && MPSOC - default "128" if ARM + default "1" if !ARM || MPU + default "8" if RCAR3 + default "4" if QEMU + default "4" if MPSOC + default "128" help Controls the build-time size of various arrays and bitmaps associated with multiple-cpu management.
