104 prompt "Processor type"
110 This is the processor type of your CPU. This information is
111 used for optimizing purposes. In order to compile a kernel
112 that can run on all 32-bit PA CPUs (albeit not optimally fast),
113 you can specify "PA7000" here.
115 Specifying "PA8000" here will allow you to select a 64-bit kernel
116 which is required on some machines.
121 Select this option for the PCX-L processor, as used in the
122 712, 715/64, 715/80, 715/100, 715/100XC, 725/100, 743, 748,
123 D200, D210, D300, D310 and E-class
128 Select this option for the PCX-T' processor, as used in the
129 C100, C110, J100, J110, J210XC, D250, D260, D350, D360,
130 K100, K200, K210, K220, K400, K410 and K420

137 D220, D230, D320 and D330.

164 Enable this if you want to support 64bit kernel on PA-RISC platform.
166 At the moment, only people willing to use more than 2GB of RAM,
167 or having a 64bit-only capable PA-RISC machine should say Y here.
169 Since there is no 64bit userland on PA-RISC, there is no point to
170 enable this option otherwise. The 64bit kernel is significantly bigger
171 and slower than the 32bit one.
174 prompt "Kernel page size"
175 default PARISC_PAGE_SIZE_4KB
177 config PARISC_PAGE_SIZE_4KB
180 This lets you select the page size of the kernel. For best
181 performance, a page size of 16KB is recommended. For best
182 compatibility with 32bit applications, a page size of 4KB should be
183 selected (the vast majority of 32bit binaries work perfectly fine
184 with a larger page size).
186 4KB For best 32bit compatibility
187 16KB For best performance
188 64KB For best performance, might give more overhead.
190 If you don't know what to do, choose 4KB.

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

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