If you have 135 a system with only one CPU, like most personal computers, say N. If 136 you have a system with more than one CPU, say Y. 137 138 If you say N here, the kernel will run on single and multiprocessor 139 machines, but will use only one CPU of a multiprocessor machine. If 140 you say Y here, the kernel will run on many, but not all, 141 singleprocessor machines. On a singleprocessor machine, the kernel 142 will run faster if you say N here. 143 144 See also the <file:Documentation/smp.txt>, 145 <file:Documentation/nmi_watchdog.txt> and the SMP-HOWTO available 146 at <http://www.tldp.org/docs.html#howto>. 147 148 If you don't know what to do here, say N. 149 150config HOTPLUG_CPU 151 bool 152 default y if SMP 153 select HOTPLUG 154 155config ARCH_DISCONTIGMEM_ENABLE 156 bool "Discontiguous memory support (EXPERIMENTAL)" 157 depends on 64BIT && EXPERIMENTAL 158 help 159 Say Y to support efficient handling of discontiguous physical memory, 160 for architectures which are either NUMA (Non-Uniform Memory Access) 161 or have huge holes in the physical address space for other reasons. 162 See <file:Documentation/vm/numa> for more. 163 164source "kernel/Kconfig.hz" 165source "mm/Kconfig" 166 167config PREEMPT 168 bool 169# bool "Preemptible Kernel" 170 default n 171 172config COMPAT 173 def_bool y 174 depends on 64BIT 175 176config HPUX 177 bool "Support for HP-UX binaries" 178 depends on !64BIT 179 180config NR_CPUS 181 int "Maximum number of CPUs (2-32)" 182 range 2 32 183 depends on SMP 184 default "32" 185 186endmenu 187 188 189source "drivers/parisc/Kconfig" 190 191 192menu "Executable file formats" 193 194source "fs/Kconfig.binfmt" 195 196endmenu 197 198source "net/Kconfig" 199 200source "drivers/Kconfig" 201 202source "fs/Kconfig" 203 204source "arch/parisc/oprofile/Kconfig" 205 206source "arch/parisc/Kconfig.debug" 207 208source "security/Kconfig" 209 210source "crypto/Kconfig" 211 212source "lib/Kconfig" 213
