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

182 bool "Enable the -mlong-calls compiler option for big kernels"
183 def_bool y if (!MODULES)
186 If you configure the kernel to include many drivers built-in instead
187 as modules, the kernel executable may become too big, so that the
188 linker will not be able to resolve some long branches and fails to link
189 your vmlinux kernel. In that case enabling this option will help you
190 to overcome this limit by using the -mlong-calls compiler option.
192 Usually you want to say N here, unless you e.g. want to build
193 a kernel which includes all necessary drivers built-in and which can
194 be used for TFTP booting without the need to have an initrd ramdisk.
196 Enabling this option will probably slow down your kernel.
202 Enable this if you want to support 64bit kernel on PA-RISC platform.
204 At the moment, only people willing to use more than 2GB of RAM,
205 or having a 64bit-only capable PA-RISC machine should say Y here.
207 Since there is no 64bit userland on PA-RISC, there is no point to
208 enable this option otherwise. The 64bit kernel is significantly bigger
209 and slower than the 32bit one.
212 prompt "Kernel page size"
213 default PARISC_PAGE_SIZE_4KB
215 config PARISC_PAGE_SIZE_4KB
218 This lets you select the page size of the kernel. For best
219 performance, a page size of 16KB is recommended. For best
220 compatibility with 32bit applications, a page size of 4KB should be
221 selected (the vast majority of 32bit binaries work perfectly fine
222 with a larger page size).
224 4KB For best 32bit compatibility
225 16KB For best performance
226 64KB For best performance, might give more overhead.
228 If you don't know what to do, choose 4KB.

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

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