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

101 prompt "Processor type"
107 This is the processor type of your CPU. This information is
108 used for optimizing purposes. In order to compile a kernel
109 that can run on all 32-bit PA CPUs (albeit not optimally fast),
110 you can specify "PA7000" here.
112 Specifying "PA8000" here will allow you to select a 64-bit kernel
113 which is required on some machines.
118 Select this option for the PCX-L processor, as used in the
119 712, 715/64, 715/80, 715/100, 715/100XC, 725/100, 743, 748,
120 D200, D210, D300, D310 and E-class
125 Select this option for the PCX-T' processor, as used in the
126 C100, C110, J100, J110, J210XC, D250, D260, D350, D360,
127 K100, K200, K210, K220, K400, K410 and K420
132 Select this option for the PCX-L2 processor, as used in the
133 744, A180, B132L, B160L, B180L, C132L, C160L, C180L,
134 D220, D230, D320 and D330.
139 Select this option for PCX-U to PCX-W2 processors.

161 Enable this if you want to support 64bit kernel on PA-RISC platform.
163 At the moment, only people willing to use more than 2GB of RAM,
164 or having a 64bit-only capable PA-RISC machine should say Y here.
166 Since there is no 64bit userland on PA-RISC, there is no point to
167 enable this option otherwise. The 64bit kernel is significantly bigger
168 and slower than the 32bit one.
171 prompt "Kernel page size"
172 default PARISC_PAGE_SIZE_4KB if !64BIT
173 default PARISC_PAGE_SIZE_4KB if 64BIT
174 # default PARISC_PAGE_SIZE_16KB if 64BIT
176 config PARISC_PAGE_SIZE_4KB
179 This lets you select the page size of the kernel. For best
180 performance, a page size of 16KB is recommended. For best
181 compatibility with 32bit applications, a page size of 4KB should be
182 selected (the vast majority of 32bit binaries work perfectly fine
183 with a larger page size).
185 4KB For best 32bit compatibility
186 16KB For best performance
187 64KB For best performance, might give more overhead.
189 If you don't know what to do, choose 4KB.

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