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

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

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

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