22 The PA-RISC microprocessor is designed by Hewlett-Packard and used
23 in many of their workstations & servers (HP9000 700 and 800 series,
24 and later HP3000 series). The PA-RISC Linux project home page is

111 menu "Processor type and features"
114 prompt "Processor type"
120 This is the processor type of your CPU. This information is
121 used for optimizing purposes. In order to compile a kernel
122 that can run on all 32-bit PA CPUs (albeit not optimally fast),
123 you can specify "PA7000" here.
125 Specifying "PA8000" here will allow you to select a 64-bit kernel
126 which is required on some machines.
131 Select this option for the PCX-L processor, as used in the
132 712, 715/64, 715/80, 715/100, 715/100XC, 725/100, 743, 748,
133 D200, D210, D300, D310 and E-class
138 Select this option for the PCX-T' processor, as used in the
139 C100, C110, J100, J110, J210XC, D250, D260, D350, D360,
140 K100, K200, K210, K220, K400, K410 and K420
145 Select this option for the PCX-L2 processor, as used in the
146 744, A180, B132L, B160L, B180L, C132L, C160L, C180L,
147 D220, D230, D320 and D330.
152 Select this option for PCX-U to PCX-W2 processors.

174 Enable this if you want to support 64bit kernel on PA-RISC platform.
176 At the moment, only people willing to use more than 2GB of RAM,
177 or having a 64bit-only capable PA-RISC machine should say Y here.
179 Since there is no 64bit userland on PA-RISC, there is no point to
180 enable this option otherwise. The 64bit kernel is significantly bigger
181 and slower than the 32bit one.
184 prompt "Kernel page size"
185 default PARISC_PAGE_SIZE_4KB if !64BIT
186 default PARISC_PAGE_SIZE_4KB if 64BIT
187 # default PARISC_PAGE_SIZE_16KB if 64BIT
189 config PARISC_PAGE_SIZE_4KB
192 This lets you select the page size of the kernel. For best
193 performance, a page size of 16KB is recommended. For best
194 compatibility with 32bit applications, a page size of 4KB should be
195 selected (the vast majority of 32bit binaries work perfectly fine
196 with a larger page size).
198 4KB For best 32bit compatibility
199 16KB For best performance
200 64KB For best performance, might give more overhead.
202 If you don't know what to do, choose 4KB.

215 bool "Symmetric multi-processing support"
216 select USE_GENERIC_SMP_HELPERS
218 This enables support for systems with more than one CPU. If you have
219 a system with only one CPU, like most personal computers, say N. If
220 you have a system with more than one CPU, say Y.
222 If you say N here, the kernel will run on single and multiprocessor
223 machines, but will use only one CPU of a multiprocessor machine. If
224 you say Y here, the kernel will run on many, but not all,
225 singleprocessor machines. On a singleprocessor machine, the kernel
226 will run faster if you say N here.

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