105 prompt "Processor type"
111 This is the processor type of your CPU. This information is
112 used for optimizing purposes. In order to compile a kernel
113 that can run on all 32-bit PA CPUs (albeit not optimally fast),
114 you can specify "PA7000" here.
116 Specifying "PA8000" here will allow you to select a 64-bit kernel
117 which is required on some machines.
122 Select this option for the PCX-L processor, as used in the
123 712, 715/64, 715/80, 715/100, 715/100XC, 725/100, 743, 748,

165 Enable this if you want to support 64bit kernel on PA-RISC platform.
167 At the moment, only people willing to use more than 2GB of RAM,
168 or having a 64bit-only capable PA-RISC machine should say Y here.
170 Since there is no 64bit userland on PA-RISC, there is no point to
171 enable this option otherwise. The 64bit kernel is significantly bigger
172 and slower than the 32bit one.
175 prompt "Kernel page size"
176 default PARISC_PAGE_SIZE_4KB
178 config PARISC_PAGE_SIZE_4KB
181 This lets you select the page size of the kernel. For best
182 performance, a page size of 16KB is recommended. For best
183 compatibility with 32bit applications, a page size of 4KB should be
184 selected (the vast majority of 32bit binaries work perfectly fine
185 with a larger page size).
187 4KB For best 32bit compatibility
188 16KB For best performance
189 64KB For best performance, might give more overhead.
191 If you don't know what to do, choose 4KB.

204 bool "Symmetric multi-processing support"
205 select USE_GENERIC_SMP_HELPERS
207 This enables support for systems with more than one CPU. If you have
208 a system with only one CPU, like most personal computers, say N. If
209 you have a system with more than one CPU, say Y.
211 If you say N here, the kernel will run on single and multiprocessor
212 machines, but will use only one CPU of a multiprocessor machine. If
213 you say Y here, the kernel will run on many, but not all,
214 singleprocessor machines. On a singleprocessor machine, the kernel
215 will run faster if you say N here.

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