124 menu "Processor type and features"
127 prompt "Processor type"
133 This is the processor type of your CPU. This information is
134 used for optimizing purposes. In order to compile a kernel
135 that can run on all 32-bit PA CPUs (albeit not optimally fast),
136 you can specify "PA7000" here.
138 Specifying "PA8000" here will allow you to select a 64-bit kernel
139 which is required on some machines.
144 Select this option for the PCX-L processor, as used in the

184 bool "Enable the -mlong-calls compiler option for big kernels"
185 def_bool y if (!MODULES)
188 If you configure the kernel to include many drivers built-in instead
189 as modules, the kernel executable may become too big, so that the
190 linker will not be able to resolve some long branches and fails to link
191 your vmlinux kernel. In that case enabling this option will help you
192 to overcome this limit by using the -mlong-calls compiler option.
194 Usually you want to say N here, unless you e.g. want to build
195 a kernel which includes all necessary drivers built-in and which can
196 be used for TFTP booting without the need to have an initrd ramdisk.
198 Enabling this option will probably slow down your kernel.
204 Enable this if you want to support 64bit kernel on PA-RISC platform.
206 At the moment, only people willing to use more than 2GB of RAM,
207 or having a 64bit-only capable PA-RISC machine should say Y here.
209 Since there is no 64bit userland on PA-RISC, there is no point to
210 enable this option otherwise. The 64bit kernel is significantly bigger
211 and slower than the 32bit one.
214 prompt "Kernel page size"
215 default PARISC_PAGE_SIZE_4KB
217 config PARISC_PAGE_SIZE_4KB
220 This lets you select the page size of the kernel. For best
221 performance, a page size of 16KB is recommended. For best
222 compatibility with 32bit applications, a page size of 4KB should be
223 selected (the vast majority of 32bit binaries work perfectly fine
224 with a larger page size).
226 4KB For best 32bit compatibility
227 16KB For best performance
228 64KB For best performance, might give more overhead.
230 If you don't know what to do, choose 4KB.

243 bool "Symmetric multi-processing support"
245 This enables support for systems with more than one CPU. If you have
246 a system with only one CPU, say N. If you have a system with more
249 If you say N here, the kernel will run on uni- and multiprocessor
250 machines, but will use only one CPU of a multiprocessor machine. If
251 you say Y here, the kernel will run on many, but not all,
252 uniprocessor machines. On a uniprocessor machine, the kernel
253 will run faster if you say N here.
255 See also <file:Documentation/nmi_watchdog.txt> and the SMP-HOWTO
256 available at <http://www.tldp.org/docs.html#howto>.
258 If you don't know what to do here, say N.
261 bool "Use separate kernel stacks when processing interrupts"
264 If you say Y here the kernel will use separate kernel stacks
265 for handling hard and soft interrupts. This can help avoid
266 overflowing the process kernel stacks.

335 prompt "Enable seccomp to safely compute untrusted bytecode"
337 This kernel feature is useful for number crunching applications
338 that may need to compute untrusted bytecode during their
339 execution. By using pipes or other transports made available to
340 the process as file descriptors supporting the read/write
341 syscalls, it's possible to isolate those applications in
342 their own address space using seccomp. Once seccomp is
343 enabled via prctl(PR_SET_SECCOMP), it cannot be disabled
344 and the task is only allowed to execute a few safe syscalls
345 defined by each seccomp mode.
347 If unsure, say Y. Only embedded should say N here.
