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

178 bool "Enable the -mlong-calls compiler option for big kernels"
179 def_bool y if (!MODULES)
182 If you configure the kernel to include many drivers built-in instead
183 as modules, the kernel executable may become too big, so that the
184 linker will not be able to resolve some long branches and fails to link
185 your vmlinux kernel. In that case enabling this option will help you
186 to overcome this limit by using the -mlong-calls compiler option.
188 Usually you want to say N here, unless you e.g. want to build
189 a kernel which includes all necessary drivers built-in and which can
190 be used for TFTP booting without the need to have an initrd ramdisk.
192 Enabling this option will probably slow down your kernel.
198 Enable this if you want to support 64bit kernel on PA-RISC platform.
200 At the moment, only people willing to use more than 2GB of RAM,
201 or having a 64bit-only capable PA-RISC machine should say Y here.
203 Since there is no 64bit userland on PA-RISC, there is no point to
204 enable this option otherwise. The 64bit kernel is significantly bigger
205 and slower than the 32bit one.
208 prompt "Kernel page size"
209 default PARISC_PAGE_SIZE_4KB
211 config PARISC_PAGE_SIZE_4KB
214 This lets you select the page size of the kernel. For best
215 performance, a page size of 16KB is recommended. For best
216 compatibility with 32bit applications, a page size of 4KB should be
217 selected (the vast majority of 32bit binaries work perfectly fine
218 with a larger page size).
220 4KB For best 32bit compatibility
221 16KB For best performance
222 64KB For best performance, might give more overhead.
224 If you don't know what to do, choose 4KB.

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

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