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

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

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

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