Sandro Posted May 8, 2015 Report Share Posted May 8, 2015 Hello; Gentoo-sources the maximum number of CPU "visible" is 512. in Fedora for example is 4096. This is related to some setting in my custom kernel or depends on some additional patch? Excuse my curiosity :) Link to comment Share on other sites More sharing options...
spectromas Posted May 8, 2015 Report Share Posted May 8, 2015 nconfig gives this information for that option: This allows you to specify the maximum number of CPUs which this kernel will support. If CPUMASK_OFFSTACK is enabled, the maximum supported value is 4096, otherwise the maximum value is 512. The minimum value which makes sense is 2.
