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

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

170 depends on PA7000 || PA7100LC || PA7200 || PA7300LC
174 depends on PA8X00 || PA7200
180 Enable this if you want to support 64bit kernel on PA-RISC platform.
182 At the moment, only people willing to use more than 2GB of RAM,
183 or having a 64bit-only capable PA-RISC machine should say Y here.
185 Since there is no 64bit userland on PA-RISC, there is no point to
186 enable this option otherwise. The 64bit kernel is significantly bigger
187 and slower than the 32bit one.
190 prompt "Kernel page size"
191 default PARISC_PAGE_SIZE_4KB if !64BIT
192 default PARISC_PAGE_SIZE_4KB if 64BIT
193 # default PARISC_PAGE_SIZE_16KB if 64BIT
195 config PARISC_PAGE_SIZE_4KB
198 This lets you select the page size of the kernel. For best
199 performance, a page size of 16KB is recommended. For best
200 compatibility with 32bit applications, a page size of 4KB should be
201 selected (the vast majority of 32bit binaries work perfectly fine
202 with a larger page size).
204 4KB For best 32bit compatibility
205 16KB For best performance
206 64KB For best performance, might give more overhead.
208 If you don't know what to do, choose 4KB.

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