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

183 bool "Enable the -mlong-calls compiler option for big kernels"
184 def_bool y if (!MODULES)
187 If you configure the kernel to include many drivers built-in instead
188 as modules, the kernel executable may become too big, so that the
189 linker will not be able to resolve some long branches and fails to link
190 your vmlinux kernel. In that case enabling this option will help you
191 to overcome this limit by using the -mlong-calls compiler option.
193 Usually you want to say N here, unless you e.g. want to build
194 a kernel which includes all necessary drivers built-in and which can
195 be used for TFTP booting without the need to have an initrd ramdisk.
197 Enabling this option will probably slow down your kernel.
203 Enable this if you want to support 64bit kernel on PA-RISC platform.
205 At the moment, only people willing to use more than 2GB of RAM,
206 or having a 64bit-only capable PA-RISC machine should say Y here.
208 Since there is no 64bit userland on PA-RISC, there is no point to
209 enable this option otherwise. The 64bit kernel is significantly bigger
210 and slower than the 32bit one.
213 prompt "Kernel page size"
214 default PARISC_PAGE_SIZE_4KB
216 config PARISC_PAGE_SIZE_4KB
219 This lets you select the page size of the kernel. For best
220 performance, a page size of 16KB is recommended. For best
221 compatibility with 32bit applications, a page size of 4KB should be
222 selected (the vast majority of 32bit binaries work perfectly fine
223 with a larger page size).
225 4KB For best 32bit compatibility
226 16KB For best performance
227 64KB For best performance, might give more overhead.
229 If you don't know what to do, choose 4KB.

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

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