128 menu "Processor type and features"
131 prompt "Processor type"
137 This is the processor type of your CPU. This information is
138 used for optimizing purposes. In order to compile a kernel
139 that can run on all 32-bit PA CPUs (albeit not optimally fast),
140 you can specify "PA7000" here.
142 Specifying "PA8000" here will allow you to select a 64-bit kernel
143 which is required on some machines.
148 Select this option for the PCX-L processor, as used in the
149 712, 715/64, 715/80, 715/100, 715/100XC, 725/100, 743, 748,

188 bool "Enable the -mlong-calls compiler option for big kernels"
189 def_bool y if (!MODULES)
192 If you configure the kernel to include many drivers built-in instead
193 as modules, the kernel executable may become too big, so that the
194 linker will not be able to resolve some long branches and fails to link
195 your vmlinux kernel. In that case enabling this option will help you
196 to overcome this limit by using the -mlong-calls compiler option.
198 Usually you want to say N here, unless you e.g. want to build
199 a kernel which includes all necessary drivers built-in and which can
200 be used for TFTP booting without the need to have an initrd ramdisk.
202 Enabling this option will probably slow down your kernel.
208 Enable this if you want to support 64bit kernel on PA-RISC platform.
210 At the moment, only people willing to use more than 2GB of RAM,
211 or having a 64bit-only capable PA-RISC machine should say Y here.
213 Since there is no 64bit userland on PA-RISC, there is no point to
214 enable this option otherwise. The 64bit kernel is significantly bigger
215 and slower than the 32bit one.
218 prompt "Kernel page size"
219 default PARISC_PAGE_SIZE_4KB
221 config PARISC_PAGE_SIZE_4KB
224 This lets you select the page size of the kernel. For best
225 performance, a page size of 16KB is recommended. For best
226 compatibility with 32bit applications, a page size of 4KB should be
227 selected (the vast majority of 32bit binaries work perfectly fine
228 with a larger page size).
230 4KB For best 32bit compatibility
231 16KB For best performance
232 64KB For best performance, might give more overhead.
234 If you don't know what to do, choose 4KB.

240 config PARISC_PAGE_SIZE_64KB
247 bool "Symmetric multi-processing support"
249 This enables support for systems with more than one CPU. If you have
250 a system with only one CPU, say N. If you have a system with more
253 If you say N here, the kernel will run on uni- and multiprocessor
254 machines, but will use only one CPU of a multiprocessor machine. If
255 you say Y here, the kernel will run on many, but not all,
256 uniprocessor machines. On a uniprocessor machine, the kernel
257 will run faster if you say N here.
259 See also <file:Documentation/nmi_watchdog.txt> and the SMP-HOWTO
260 available at <http://www.tldp.org/docs.html#howto>.
262 If you don't know what to do here, say N.
265 bool "Use separate kernel stacks when processing interrupts"
268 If you say Y here the kernel will use separate kernel stacks
269 for handling hard and soft interrupts. This can help avoid
270 overflowing the process kernel stacks.

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