23 The PA-RISC microprocessor is designed by Hewlett-Packard and used

25 and later HP3000 series). The PA-RISC Linux project home page is

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

169 depends on PA8X00 || PA7200
175 Enable this if you want to support 64bit kernel on PA-RISC platform.
177 At the moment, only people willing to use more than 2GB of RAM,
178 or having a 64bit-only capable PA-RISC machine should say Y here.
180 Since there is no 64bit userland on PA-RISC, there is no point to
181 enable this option otherwise. The 64bit kernel is significantly bigger
182 and slower than the 32bit one.
185 prompt "Kernel page size"
186 default PARISC_PAGE_SIZE_4KB if !64BIT
187 default PARISC_PAGE_SIZE_4KB if 64BIT
188 # default PARISC_PAGE_SIZE_16KB if 64BIT
190 config PARISC_PAGE_SIZE_4KB
193 This lets you select the page size of the kernel. For best
194 performance, a page size of 16KB is recommended. For best
195 compatibility with 32bit applications, a page size of 4KB should be
196 selected (the vast majority of 32bit binaries work perfectly fine
197 with a larger page size).
199 4KB For best 32bit compatibility
200 16KB For best performance
201 64KB For best performance, might give more overhead.
203 If you don't know what to do, choose 4KB.

216 bool "Symmetric multi-processing support"
217 select USE_GENERIC_SMP_HELPERS
219 This enables support for systems with more than one CPU. If you have
220 a system with only one CPU, like most personal computers, say N. If
221 you have a system with more than one CPU, say Y.
223 If you say N here, the kernel will run on single and multiprocessor
224 machines, but will use only one CPU of a multiprocessor machine. If
225 you say Y here, the kernel will run on many, but not all,
226 singleprocessor machines. On a singleprocessor machine, the kernel
227 will run faster if you say N here.
229 See also <file:Documentation/nmi_watchdog.txt> and the SMP-HOWTO
230 available at <http://www.tldp.org/docs.html#howto>.
232 If you don't know what to do here, say N.
