6 mainmenu "Linux/PA-RISC Kernel Configuration"
13 The PA-RISC microprocessor is designed by Hewlett-Packard and used
14 in many of their workstations & servers (HP9000 700 and 800 series,
15 and later HP3000 series). The PA-RISC Linux project home page is
16 at <http://www.parisc-linux.org/>.

99 prompt "Processor type"
105 This is the processor type of your CPU. This information is
106 used for optimizing purposes. In order to compile a kernel
107 that can run on all 32-bit PA CPUs (albeit not optimally fast),
108 you can specify "PA7000" here.
110 Specifying "PA8000" here will allow you to select a 64-bit kernel
111 which is required on some machines.
116 Select this option for the PCX-L processor, as used in the
117 712, 715/64, 715/80, 715/100, 715/100XC, 725/100, 743, 748,
118 D200, D210, D300, D310 and E-class
123 Select this option for the PCX-T' processor, as used in the
124 C100, C110, J100, J110, J210XC, D250, D260, D350, D360,
125 K100, K200, K210, K220, K400, K410 and K420
130 Select this option for the PCX-L2 processor, as used in the
131 744, A180, B132L, B160L, B180L, C132L, C160L, C180L,
132 D220, D230, D320 and D330.
137 Select this option for PCX-U to PCX-W2 processors.

159 Enable this if you want to support 64bit kernel on PA-RISC platform.
161 At the moment, only people willing to use more than 2GB of RAM,
162 or having a 64bit-only capable PA-RISC machine should say Y here.
164 Since there is no 64bit userland on PA-RISC, there is no point to
165 enable this option otherwise. The 64bit kernel is significantly bigger
166 and slower than the 32bit one.
169 prompt "Kernel page size"
170 default PARISC_PAGE_SIZE_4KB if !64BIT
171 default PARISC_PAGE_SIZE_4KB if 64BIT
172 # default PARISC_PAGE_SIZE_16KB if 64BIT
174 config PARISC_PAGE_SIZE_4KB
177 This lets you select the page size of the kernel. For best
178 performance, a page size of 16KB is recommended. For best
179 compatibility with 32bit applications, a page size of 4KB should be
180 selected (the vast majority of 32bit binaries work perfectly fine
181 with a larger page size).
183 4KB For best 32bit compatibility
184 16KB For best performance
185 64KB For best performance, might give more overhead.
187 If you don't know what to do, choose 4KB.

200 bool "Symmetric multi-processing support"
201 select USE_GENERIC_SMP_HELPERS
203 This enables support for systems with more than one CPU. If you have
204 a system with only one CPU, like most personal computers, say N. If
205 you have a system with more than one CPU, say Y.
207 If you say N here, the kernel will run on single and multiprocessor
208 machines, but will use only one CPU of a multiprocessor machine. If
209 you say Y here, the kernel will run on many, but not all,
210 singleprocessor machines. On a singleprocessor machine, the kernel
211 will run faster if you say N here.
213 See also <file:Documentation/nmi_watchdog.txt> and the SMP-HOWTO
214 available at <http://www.tldp.org/docs.html#howto>.
216 If you don't know what to do here, say N.
