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

190 bool "Enable the -mlong-calls compiler option for big kernels"
191 def_bool y if (!MODULES)
194 If you configure the kernel to include many drivers built-in instead
195 as modules, the kernel executable may become too big, so that the
196 linker will not be able to resolve some long branches and fails to link
197 your vmlinux kernel. In that case enabling this option will help you
198 to overcome this limit by using the -mlong-calls compiler option.
200 Usually you want to say N here, unless you e.g. want to build
201 a kernel which includes all necessary drivers built-in and which can
202 be used for TFTP booting without the need to have an initrd ramdisk.
204 Enabling this option will probably slow down your kernel.
210 Enable this if you want to support 64bit kernel on PA-RISC platform.
212 At the moment, only people willing to use more than 2GB of RAM,
213 or having a 64bit-only capable PA-RISC machine should say Y here.
215 Since there is no 64bit userland on PA-RISC, there is no point to
216 enable this option otherwise. The 64bit kernel is significantly bigger
217 and slower than the 32bit one.
220 prompt "Kernel page size"
221 default PARISC_PAGE_SIZE_4KB
223 config PARISC_PAGE_SIZE_4KB
226 This lets you select the page size of the kernel. For best
227 performance, a page size of 16KB is recommended. For best
228 compatibility with 32bit applications, a page size of 4KB should be
229 selected (the vast majority of 32bit binaries work perfectly fine
230 with a larger page size).
232 4KB For best 32bit compatibility
233 16KB For best performance
234 64KB For best performance, might give more overhead.
236 If you don't know what to do, choose 4KB.

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

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