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

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

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

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