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/>.

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

154 depends on PA8X00 || PA7200
160 Enable this if you want to support 64bit kernel on PA-RISC platform.
162 At the moment, only people willing to use more than 2GB of RAM,
163 or having a 64bit-only capable PA-RISC machine should say Y here.
165 Since there is no 64bit userland on PA-RISC, there is no point to
166 enable this option otherwise. The 64bit kernel is significantly bigger
167 and slower than the 32bit one.
170 prompt "Kernel page size"
171 default PARISC_PAGE_SIZE_4KB if !64BIT
172 default PARISC_PAGE_SIZE_4KB if 64BIT
173 # default PARISC_PAGE_SIZE_16KB if 64BIT
175 config PARISC_PAGE_SIZE_4KB
178 This lets you select the page size of the kernel. For best
179 performance, a page size of 16KB is recommended. For best
180 compatibility with 32bit applications, a page size of 4KB should be
181 selected (the vast majority of 32bit binaries work perfectly fine
182 with a larger page size).
184 4KB For best 32bit compatibility
185 16KB For best performance
186 64KB For best performance, might give more overhead.
188 If you don't know what to do, choose 4KB.

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