115 prompt "Processor type"
121 This is the processor type of your CPU. This information is
122 used for optimizing purposes. In order to compile a kernel
123 that can run on all 32-bit PA CPUs (albeit not optimally fast),
124 you can specify "PA7000" here.
126 Specifying "PA8000" here will allow you to select a 64-bit kernel
127 which is required on some machines.
132 Select this option for the PCX-L processor, as used in the

172 bool "Enable the -mlong-calls compiler option for big kernels"
173 def_bool y if (!MODULES)
176 If you configure the kernel to include many drivers built-in instead
177 as modules, the kernel executable may become too big, so that the
178 linker will not be able to resolve some long branches and fails to link
179 your vmlinux kernel. In that case enabling this option will help you
180 to overcome this limit by using the -mlong-calls compiler option.
182 Usually you want to say N here, unless you e.g. want to build
183 a kernel which includes all necessary drivers built-in and which can
184 be used for TFTP booting without the need to have an initrd ramdisk.
186 Enabling this option will probably slow down your kernel.
192 Enable this if you want to support 64bit kernel on PA-RISC platform.
194 At the moment, only people willing to use more than 2GB of RAM,
195 or having a 64bit-only capable PA-RISC machine should say Y here.
197 Since there is no 64bit userland on PA-RISC, there is no point to
198 enable this option otherwise. The 64bit kernel is significantly bigger
199 and slower than the 32bit one.
202 prompt "Kernel page size"
203 default PARISC_PAGE_SIZE_4KB
205 config PARISC_PAGE_SIZE_4KB
208 This lets you select the page size of the kernel. For best
209 performance, a page size of 16KB is recommended. For best
210 compatibility with 32bit applications, a page size of 4KB should be
211 selected (the vast majority of 32bit binaries work perfectly fine
212 with a larger page size).
214 4KB For best 32bit compatibility
215 16KB For best performance
216 64KB For best performance, might give more overhead.
218 If you don't know what to do, choose 4KB.

231 bool "Symmetric multi-processing support"
233 This enables support for systems with more than one CPU. If you have
234 a system with only one CPU, say N. If you have a system with more
237 If you say N here, the kernel will run on uni- and multiprocessor
238 machines, but will use only one CPU of a multiprocessor machine. If
239 you say Y here, the kernel will run on many, but not all,
240 uniprocessor machines. On a uniprocessor machine, the kernel
241 will run faster if you say N here.
243 See also <file:Documentation/nmi_watchdog.txt> and the SMP-HOWTO
244 available at <http://www.tldp.org/docs.html#howto>.
246 If you don't know what to do here, say N.
249 bool "Use separate kernel stacks when processing interrupts"
252 If you say Y here the kernel will use separate kernel stacks
253 for handling hard and soft interrupts. This can help avoid
254 overflowing the process kernel stacks.
