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/>.

94 menu "Processor type and features"
97 prompt "Processor type"
103 This is the processor type of your CPU. This information is
104 used for optimizing purposes. In order to compile a kernel
105 that can run on all 32-bit PA CPUs (albeit not optimally fast),
106 you can specify "PA7000" here.
108 Specifying "PA8000" here will allow you to select a 64-bit kernel
109 which is required on some machines.
114 Select this option for the PCX-L processor, as used in the
115 712, 715/64, 715/80, 715/100, 715/100XC, 725/100, 743, 748,
116 D200, D210, D300, D310 and E-class
121 Select this option for the PCX-T' processor, as used in the
122 C100, C110, J100, J110, J210XC, D250, D260, D350, D360,
123 K100, K200, K210, K220, K400, K410 and K420
128 Select this option for the PCX-L2 processor, as used in the
129 744, A180, B132L, B160L, B180L, C132L, C160L, C180L,
130 D220, D230, D320 and D330.
135 Select this option for PCX-U to PCX-W2 processors.

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

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