110 menu "Processor type and features"
113 prompt "Processor type"
119 This is the processor type of your CPU. This information is
120 used for optimizing purposes. In order to compile a kernel
121 that can run on all 32-bit PA CPUs (albeit not optimally fast),
122 you can specify "PA7000" here.
124 Specifying "PA8000" here will allow you to select a 64-bit kernel
125 which is required on some machines.
130 Select this option for the PCX-L processor, as used in the
131 712, 715/64, 715/80, 715/100, 715/100XC, 725/100, 743, 748,

139 K100, K200, K210, K220, K400, K410 and K420

170 bool "Enable the -mlong-calls compiler option for big kernels"
171 def_bool y if (!MODULES)
174 If you configure the kernel to include many drivers built-in instead
175 as modules, the kernel executable may become too big, so that the
176 linker will not be able to resolve some long branches and fails to link
177 your vmlinux kernel. In that case enabling this option will help you
178 to overcome this limit by using the -mlong-calls compiler option.
180 Usually you want to say N here, unless you e.g. want to build
181 a kernel which includes all necessary drivers built-in and which can
182 be used for TFTP booting without the need to have an initrd ramdisk.
184 Enabling this option will probably slow down your kernel.
190 Enable this if you want to support 64bit kernel on PA-RISC platform.
192 At the moment, only people willing to use more than 2GB of RAM,
193 or having a 64bit-only capable PA-RISC machine should say Y here.
195 Since there is no 64bit userland on PA-RISC, there is no point to
196 enable this option otherwise. The 64bit kernel is significantly bigger
197 and slower than the 32bit one.
200 prompt "Kernel page size"
201 default PARISC_PAGE_SIZE_4KB
203 config PARISC_PAGE_SIZE_4KB
206 This lets you select the page size of the kernel. For best
207 performance, a page size of 16KB is recommended. For best
208 compatibility with 32bit applications, a page size of 4KB should be
209 selected (the vast majority of 32bit binaries work perfectly fine
210 with a larger page size).
212 4KB For best 32bit compatibility
213 16KB For best performance
214 64KB For best performance, might give more overhead.
216 If you don't know what to do, choose 4KB.
218 config PARISC_PAGE_SIZE_16KB
222 config PARISC_PAGE_SIZE_64KB
229 bool "Symmetric multi-processing support"
230 select USE_GENERIC_SMP_HELPERS
232 This enables support for systems with more than one CPU. If you have
233 a system with only one CPU, like most personal computers, say N. If
234 you have a system with more than one CPU, say Y.
236 If you say N here, the kernel will run on single and multiprocessor
237 machines, but will use only one CPU of a multiprocessor machine. If
238 you say Y here, the kernel will run on many, but not all,
239 singleprocessor machines. On a singleprocessor machine, the kernel
240 will run faster if you say N here.
242 See also <file:Documentation/nmi_watchdog.txt> and the SMP-HOWTO
243 available at <http://www.tldp.org/docs.html#howto>.
245 If you don't know what to do here, say N.
248 bool "Use separate kernel stacks when processing interrupts"
251 If you say Y here the kernel will use separate kernel stacks
252 for handling hard and soft interrupts. This can help avoid
253 overflowing the process kernel stacks.
