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

169 bool "Enable the -mlong-calls compiler option for big kernels"
170 def_bool y if (!MODULES)
173 If you configure the kernel to include many drivers built-in instead
174 as modules, the kernel executable may become too big, so that the
175 linker will not be able to resolve some long branches and fails to link
176 your vmlinux kernel. In that case enabling this option will help you
177 to overcome this limit by using the -mlong-calls compiler option.
179 Usually you want to say N here, unless you e.g. want to build
180 a kernel which includes all necessary drivers built-in and which can
181 be used for TFTP booting without the need to have an initrd ramdisk.
183 Enabling this option will probably slow down your kernel.
189 Enable this if you want to support 64bit kernel on PA-RISC platform.
191 At the moment, only people willing to use more than 2GB of RAM,
192 or having a 64bit-only capable PA-RISC machine should say Y here.
194 Since there is no 64bit userland on PA-RISC, there is no point to
195 enable this option otherwise. The 64bit kernel is significantly bigger
196 and slower than the 32bit one.
199 prompt "Kernel page size"
200 default PARISC_PAGE_SIZE_4KB
202 config PARISC_PAGE_SIZE_4KB
205 This lets you select the page size of the kernel. For best
206 performance, a page size of 16KB is recommended. For best
207 compatibility with 32bit applications, a page size of 4KB should be
208 selected (the vast majority of 32bit binaries work perfectly fine
209 with a larger page size).
211 4KB For best 32bit compatibility
212 16KB For best performance
213 64KB For best performance, might give more overhead.
215 If you don't know what to do, choose 4KB.
217 config PARISC_PAGE_SIZE_16KB
221 config PARISC_PAGE_SIZE_64KB
228 bool "Symmetric multi-processing support"
229 select USE_GENERIC_SMP_HELPERS
231 This enables support for systems with more than one CPU. If you have
232 a system with only one CPU, like most personal computers, say N. If
233 you have a system with more than one CPU, say Y.
235 If you say N here, the kernel will run on single and multiprocessor
236 machines, but will use only one CPU of a multiprocessor machine. If
237 you say Y here, the kernel will run on many, but not all,
238 singleprocessor machines. On a singleprocessor machine, the kernel
239 will run faster if you say N here.
241 See also <file:Documentation/nmi_watchdog.txt> and the SMP-HOWTO
242 available at <http://www.tldp.org/docs.html#howto>.
244 If you don't know what to do here, say N.
247 bool "Use separate kernel stacks when processing interrupts"
250 If you say Y here the kernel will use separate kernel stacks
251 for handling hard and soft interrupts. This can help avoid
252 overflowing the process kernel stacks.
