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

114 menu "Processor type and features"
117 prompt "Processor type"
123 This is the processor type of your CPU. This information is
124 used for optimizing purposes. In order to compile a kernel
125 that can run on all 32-bit PA CPUs (albeit not optimally fast),
126 you can specify "PA7000" here.
128 Specifying "PA8000" here will allow you to select a 64-bit kernel
129 which is required on some machines.
134 Select this option for the PCX-L processor, as used in the
135 712, 715/64, 715/80, 715/100, 715/100XC, 725/100, 743, 748,
136 D200, D210, D300, D310 and E-class
141 Select this option for the PCX-T' processor, as used in the
142 C100, C110, J100, J110, J210XC, D250, D260, D350, D360,
143 K100, K200, K210, K220, K400, K410 and K420
148 Select this option for the PCX-L2 processor, as used in the
149 744, A180, B132L, B160L, B180L, C132L, C160L, C180L,
150 D220, D230, D320 and D330.
155 Select this option for PCX-U to PCX-W2 processors.

171 depends on PA8X00 || PA7200
177 Enable this if you want to support 64bit kernel on PA-RISC platform.
179 At the moment, only people willing to use more than 2GB of RAM,
180 or having a 64bit-only capable PA-RISC machine should say Y here.
182 Since there is no 64bit userland on PA-RISC, there is no point to
183 enable this option otherwise. The 64bit kernel is significantly bigger
184 and slower than the 32bit one.
187 prompt "Kernel page size"
188 default PARISC_PAGE_SIZE_4KB if !64BIT
189 default PARISC_PAGE_SIZE_4KB if 64BIT
190 # default PARISC_PAGE_SIZE_16KB if 64BIT
192 config PARISC_PAGE_SIZE_4KB
195 This lets you select the page size of the kernel. For best
196 performance, a page size of 16KB is recommended. For best
197 compatibility with 32bit applications, a page size of 4KB should be
198 selected (the vast majority of 32bit binaries work perfectly fine
199 with a larger page size).
201 4KB For best 32bit compatibility
202 16KB For best performance
203 64KB For best performance, might give more overhead.
205 If you don't know what to do, choose 4KB.

213 depends on PA8X00 && EXPERIMENTAL
218 bool "Symmetric multi-processing support"
219 select USE_GENERIC_SMP_HELPERS
221 This enables support for systems with more than one CPU. If you have
222 a system with only one CPU, like most personal computers, say N. If
223 you have a system with more than one CPU, say Y.
225 If you say N here, the kernel will run on single and multiprocessor
226 machines, but will use only one CPU of a multiprocessor machine. If
227 you say Y here, the kernel will run on many, but not all,
228 singleprocessor machines. On a singleprocessor machine, the kernel
229 will run faster if you say N here.
231 See also <file:Documentation/nmi_watchdog.txt> and the SMP-HOWTO
232 available at <http://www.tldp.org/docs.html#howto>.
234 If you don't know what to do here, say N.
