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

138 string "Default kernel command string"
141 On some platforms, there is currently no way for the boot loader
142 to pass arguments to the kernel. For these, you should supply some
143 command-line options at build time by entering them here. At a
144 minimum, you should specify the memory size and the root device
145 (e.g., mem=64M root=/dev/nfs).
147 config HEXAGON_ANGEL_TRAPS
148 bool "Use Angel Traps"
151 Enable angel debug traps (for printk's).
154 bool "Multi-Processing support"
156 Enables SMP support in the kernel. If unsure, say "Y"
159 int "Maximum number of CPUs" if SMP
164 This allows you to specify the maximum number of CPUs which this
165 kernel will support. The maximum supported value is 6 and the
166 minimum value which makes sense is 2.
168 This is purely to save memory - each supported CPU adds
169 approximately eight kilobytes to the kernel image.

175 Changes the default page size; use with caution.
