Hi,
I have multicore machines with greater than 8 CPUs
I would like to support more than the default 8 CPUs (i.e. CONFIG_NR_CPUS=8)
When I run make linux-xconfig and search for the following parameter "X86_BIGSMP"; unable to set.
The search/find actually discovers "X86_BIGSMP" and gives a description only. :(
Support for big SMP systems with more than 8 CPUs (X86_BIGSMP)
CONFIG_X86_BIGSMP:
This option is needed for the systems that have more than 8 CPUs
Symbol: X86_BIGSMP [=n]
Type : boolean
Prompt: Support for big SMP systems with more than 8 CPUs
Location:
-> Processor type and features
Defined at arch/x86/Kconfig:330
Depends on: X86_32 [=n] && SMP [=y]
How can I find and set this parameter?
Or should I just select "CONFIG_MAXSMP" and call it a day?
Thanks in advance for your help.
Cheers,
Ernesto
