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

181 bool "Enable the -mlong-calls compiler option for big kernels"
182 def_bool y if (!MODULES)
185 If you configure the kernel to include many drivers built-in instead
186 as modules, the kernel executable may become too big, so that the
187 linker will not be able to resolve some long branches and fails to link
188 your vmlinux kernel. In that case enabling this option will help you
189 to overcome this limit by using the -mlong-calls compiler option.
191 Usually you want to say N here, unless you e.g. want to build
192 a kernel which includes all necessary drivers built-in and which can
193 be used for TFTP booting without the need to have an initrd ramdisk.
195 Enabling this option will probably slow down your kernel.
201 Enable this if you want to support 64bit kernel on PA-RISC platform.
203 At the moment, only people willing to use more than 2GB of RAM,
204 or having a 64bit-only capable PA-RISC machine should say Y here.
206 Since there is no 64bit userland on PA-RISC, there is no point to
207 enable this option otherwise. The 64bit kernel is significantly bigger
208 and slower than the 32bit one.
211 prompt "Kernel page size"
212 default PARISC_PAGE_SIZE_4KB
214 config PARISC_PAGE_SIZE_4KB
217 This lets you select the page size of the kernel. For best
218 performance, a page size of 16KB is recommended. For best
219 compatibility with 32bit applications, a page size of 4KB should be
220 selected (the vast majority of 32bit binaries work perfectly fine
221 with a larger page size).
223 4KB For best 32bit compatibility
224 16KB For best performance
225 64KB For best performance, might give more overhead.
227 If you don't know what to do, choose 4KB.

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

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