151 This is the processor type of your CPU. This information is
152 used for optimizing purposes. In order to compile a kernel
153 that can run on all 32-bit PA CPUs (albeit not optimally fast),
154 you can specify "PA7000" here.
156 Specifying "PA8000" here will allow you to select a 64-bit kernel
157 which is required on some machines.
162 Select this option for the PCX-L processor, as used in the

202 bool "Enable the -mlong-calls compiler option for big kernels"
203 def_bool y if (!MODULES)
206 If you configure the kernel to include many drivers built-in instead
207 as modules, the kernel executable may become too big, so that the
208 linker will not be able to resolve some long branches and fails to link
209 your vmlinux kernel. In that case enabling this option will help you
210 to overcome this limit by using the -mlong-calls compiler option.
212 Usually you want to say N here, unless you e.g. want to build
213 a kernel which includes all necessary drivers built-in and which can
214 be used for TFTP booting without the need to have an initrd ramdisk.
216 Enabling this option will probably slow down your kernel.
222 Enable this if you want to support 64bit kernel on PA-RISC platform.
224 At the moment, only people willing to use more than 2GB of RAM,
225 or having a 64bit-only capable PA-RISC machine should say Y here.
227 Since there is no 64bit userland on PA-RISC, there is no point to
228 enable this option otherwise. The 64bit kernel is significantly bigger
229 and slower than the 32bit one.
232 prompt "Kernel page size"
233 default PARISC_PAGE_SIZE_4KB
235 config PARISC_PAGE_SIZE_4KB
238 This lets you select the page size of the kernel. For best
239 performance, a page size of 16KB is recommended. For best
240 compatibility with 32bit applications, a page size of 4KB should be
241 selected (the vast majority of 32bit binaries work perfectly fine
242 with a larger page size).
244 4KB For best 32bit compatibility
245 16KB For best performance
246 64KB For best performance, might give more overhead.
248 If you don't know what to do, choose 4KB.

261 bool "Build kernel as self-extracting executable"
264 Say Y if you want to build the parisc kernel as a kind of
265 self-extracting executable.
267 If you say N here, the kernel will be compressed with gzip
268 which can be loaded by the palo bootloader directly too.
270 If you don't know what to do here, say Y.
273 bool "Symmetric multi-processing support"
275 This enables support for systems with more than one CPU. If you have
276 a system with only one CPU, say N. If you have a system with more
279 If you say N here, the kernel will run on uni- and multiprocessor
280 machines, but will use only one CPU of a multiprocessor machine. If
281 you say Y here, the kernel will run on many, but not all,
282 uniprocessor machines. On a uniprocessor machine, the kernel
283 will run faster if you say N here.
285 See also <file:Documentation/nmi_watchdog.txt> and the SMP-HOWTO
286 available at <http://www.tldp.org/docs.html#howto>.
288 If you don't know what to do here, say N.
291 bool "Use separate kernel stacks when processing interrupts"
294 If you say Y here the kernel will use separate kernel stacks
295 for handling hard and soft interrupts. This can help avoid
296 overflowing the process kernel stacks.

367 This kernel feature is useful for number crunching applications
368 that may need to compute untrusted bytecode during their
369 execution. By using pipes or other transports made available to
370 the process as file descriptors supporting the read/write
371 syscalls, it's possible to isolate those applications in
372 their own address space using seccomp. Once seccomp is
373 enabled via prctl(PR_SET_SECCOMP), it cannot be disabled
374 and the task is only allowed to execute a few safe syscalls
375 defined by each seccomp mode.
377 If unsure, say Y. Only embedded should say N here.
