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

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

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

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