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

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

175 default PAGE_SIZE_4KB
177 Changes the default page size; use with caution.
