120 menu "Processor type and features"
123 prompt "Processor type"
129 This is the processor type of your CPU. This information is
130 used for optimizing purposes. In order to compile a kernel
131 that can run on all 32-bit PA CPUs (albeit not optimally fast),
132 you can specify "PA7000" here.
134 Specifying "PA8000" here will allow you to select a 64-bit kernel
135 which is required on some machines.
140 Select this option for the PCX-L processor, as used in the
141 712, 715/64, 715/80, 715/100, 715/100XC, 725/100, 743, 748,

149 K100, K200, K210, K220, K400, K410 and K420

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

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

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