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

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

175 depends on PA8X00 || PA7200
181 Enable this if you want to support 64bit kernel on PA-RISC platform.
183 At the moment, only people willing to use more than 2GB of RAM,
184 or having a 64bit-only capable PA-RISC machine should say Y here.
186 Since there is no 64bit userland on PA-RISC, there is no point to
187 enable this option otherwise. The 64bit kernel is significantly bigger
188 and slower than the 32bit one.
191 prompt "Kernel page size"
192 default PARISC_PAGE_SIZE_4KB if !64BIT
193 default PARISC_PAGE_SIZE_4KB if 64BIT
194 # default PARISC_PAGE_SIZE_16KB if 64BIT
196 config PARISC_PAGE_SIZE_4KB
199 This lets you select the page size of the kernel. For best
200 performance, a page size of 16KB is recommended. For best
201 compatibility with 32bit applications, a page size of 4KB should be
202 selected (the vast majority of 32bit binaries work perfectly fine
203 with a larger page size).
205 4KB For best 32bit compatibility
206 16KB For best performance
207 64KB For best performance, might give more overhead.
209 If you don't know what to do, choose 4KB.

212 bool "16KB (EXPERIMENTAL)"

216 bool "64KB (EXPERIMENTAL)"
217 depends on PA8X00 && EXPERIMENTAL
222 bool "Symmetric multi-processing support"
223 select USE_GENERIC_SMP_HELPERS
225 This enables support for systems with more than one CPU. If you have
226 a system with only one CPU, like most personal computers, say N. If
227 you have a system with more than one CPU, say Y.
229 If you say N here, the kernel will run on single and multiprocessor
230 machines, but will use only one CPU of a multiprocessor machine. If
231 you say Y here, the kernel will run on many, but not all,
232 singleprocessor machines. On a singleprocessor machine, the kernel
233 will run faster if you say N here.
235 See also <file:Documentation/nmi_watchdog.txt> and the SMP-HOWTO
236 available at <http://www.tldp.org/docs.html#howto>.
238 If you don't know what to do here, say N.
