31 performance and low power across a wide variety of applications.

103 string "Default kernel command string"
106 On some platforms, there is currently no way for the boot loader
107 to pass arguments to the kernel. For these, you should supply some
108 command-line options at build time by entering them here. At a
109 minimum, you should specify the memory size and the root device
110 (e.g., mem=64M root=/dev/nfs).
113 bool "Multi-Processing support"
115 Enables SMP support in the kernel. If unsure, say "Y"
118 int "Maximum number of CPUs" if SMP
123 This allows you to specify the maximum number of CPUs which this
124 kernel will support. The maximum supported value is 6 and the
125 minimum value which makes sense is 2.
127 This is purely to save memory - each supported CPU adds
128 approximately eight kilobytes to the kernel image.
131 prompt "Kernel page size"
132 default PAGE_SIZE_4KB
134 Changes the default page size; use with caution.
