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

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

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

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