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

127 C100, C110, J100, J110, J210XC, D250, D260, D350, D360,
128 K100, K200, K210, K220, K400, K410 and K420

135 D220, D230, D320 and D330.

162 Enable this if you want to support 64bit kernel on PA-RISC platform.
164 At the moment, only people willing to use more than 2GB of RAM,
165 or having a 64bit-only capable PA-RISC machine should say Y here.
167 Since there is no 64bit userland on PA-RISC, there is no point to
168 enable this option otherwise. The 64bit kernel is significantly bigger
169 and slower than the 32bit one.
172 prompt "Kernel page size"
173 default PARISC_PAGE_SIZE_4KB
175 config PARISC_PAGE_SIZE_4KB
178 This lets you select the page size of the kernel. For best
179 performance, a page size of 16KB is recommended. For best
180 compatibility with 32bit applications, a page size of 4KB should be
181 selected (the vast majority of 32bit binaries work perfectly fine
182 with a larger page size).
184 4KB For best 32bit compatibility
185 16KB For best performance
186 64KB For best performance, might give more overhead.
188 If you don't know what to do, choose 4KB.

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

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