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

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

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

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