105 menu "Processor type and features"
108 prompt "Processor type"
114 This is the processor type of your CPU. This information is
115 used for optimizing purposes. In order to compile a kernel
116 that can run on all 32-bit PA CPUs (albeit not optimally fast),
117 you can specify "PA7000" here.
119 Specifying "PA8000" here will allow you to select a 64-bit kernel
120 which is required on some machines.
125 Select this option for the PCX-L processor, as used in the
126 712, 715/64, 715/80, 715/100, 715/100XC, 725/100, 743, 748,

132 Select this option for the PCX-T' processor, as used in the
133 C100, C110, J100, J110, J210XC, D250, D260, D350, D360,
134 K100, K200, K210, K220, K400, K410 and K420

165 bool "Enable the -mlong-calls compiler option for big kernels"
166 def_bool y if (!MODULES)
169 If you configure the kernel to include many drivers built-in instead
170 as modules, the kernel executable may become too big, so that the
171 linker will not be able to resolve some long branches and fails to link
172 your vmlinux kernel. In that case enabling this option will help you
173 to overcome this limit by using the -mlong-calls compiler option.
175 Usually you want to say N here, unless you e.g. want to build
176 a kernel which includes all necessary drivers built-in and which can
177 be used for TFTP booting without the need to have an initrd ramdisk.
179 Enabling this option will probably slow down your kernel.
185 Enable this if you want to support 64bit kernel on PA-RISC platform.
187 At the moment, only people willing to use more than 2GB of RAM,
188 or having a 64bit-only capable PA-RISC machine should say Y here.
190 Since there is no 64bit userland on PA-RISC, there is no point to
191 enable this option otherwise. The 64bit kernel is significantly bigger
192 and slower than the 32bit one.
195 prompt "Kernel page size"
196 default PARISC_PAGE_SIZE_4KB
198 config PARISC_PAGE_SIZE_4KB
201 This lets you select the page size of the kernel. For best
202 performance, a page size of 16KB is recommended. For best
203 compatibility with 32bit applications, a page size of 4KB should be
204 selected (the vast majority of 32bit binaries work perfectly fine
205 with a larger page size).
207 4KB For best 32bit compatibility
208 16KB For best performance
209 64KB For best performance, might give more overhead.
211 If you don't know what to do, choose 4KB.

224 bool "Symmetric multi-processing support"
225 select USE_GENERIC_SMP_HELPERS
227 This enables support for systems with more than one CPU. If you have
228 a system with only one CPU, like most personal computers, say N. If
229 you have a system with more than one CPU, say Y.
231 If you say N here, the kernel will run on single and multiprocessor
232 machines, but will use only one CPU of a multiprocessor machine. If
233 you say Y here, the kernel will run on many, but not all,
234 singleprocessor machines. On a singleprocessor machine, the kernel
235 will run faster if you say N here.

238 available at <http://www.tldp.org/docs.html#howto>.
