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

134 D220, D230, D320 and D330.

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

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

214 available at <http://www.tldp.org/docs.html#howto>.
216 If you don't know what to do here, say N.
