Whitespace issues aside, I have applied the patch on top of kernel 6.1.55 and tested on both a dual-socket Ampere Altra machine with < 256 CPUs, and a dual-socket AmpereOne machine with > 256 CPUs. Works as expected, with all CPUs visible and functional.
config NR_CPUS int "Maximum number of CPUs (2-4096)" range 2 4096 - default "256" + default 512
Nit: the new default value should be in quotation marks, if we want to be pedantic Tested-by: Eric Mackay <redacted> _______________________________________________ linux-arm-kernel mailing list linux-arm-kernel@lists.infradead.org http://lists.infradead.org/mailman/listinfo/linux-arm-kernel
