126 menu "Processor type and features"
129 prompt "Processor type"
135 This is the processor type of your CPU. This information is
136 used for optimizing purposes. In order to compile a kernel
137 that can run on all 32-bit PA CPUs (albeit not optimally fast),
138 you can specify "PA7000" here.
140 Specifying "PA8000" here will allow you to select a 64-bit kernel
141 which is required on some machines.
146 Select this option for the PCX-L processor, as used in the
147 712, 715/64, 715/80, 715/100, 715/100XC, 725/100, 743, 748,

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

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

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