16 The PA-RISC microprocessor is designed by Hewlett-Packard and used
17 in many of their workstations & servers (HP9000 700 and 800 series,
18 and later HP3000 series). The PA-RISC Linux project home page is
19 at <http://www.parisc-linux.org/>.

102 prompt "Processor type"
108 This is the processor type of your CPU. This information is
109 used for optimizing purposes. In order to compile a kernel
110 that can run on all 32-bit PA CPUs (albeit not optimally fast),
111 you can specify "PA7000" here.
113 Specifying "PA8000" here will allow you to select a 64-bit kernel
114 which is required on some machines.
119 Select this option for the PCX-L processor, as used in the
120 712, 715/64, 715/80, 715/100, 715/100XC, 725/100, 743, 748,
121 D200, D210, D300, D310 and E-class
126 Select this option for the PCX-T' processor, as used in the
127 C100, C110, J100, J110, J210XC, D250, D260, D350, D360,
128 K100, K200, K210, K220, K400, K410 and K420
133 Select this option for the PCX-L2 processor, as used in the
134 744, A180, B132L, B160L, B180L, C132L, C160L, C180L,
135 D220, D230, D320 and D330.
140 Select this option for PCX-U to PCX-W2 processors.

162 Enable this if you want to support 64bit kernel on PA-RISC platform.
164 At the moment, only people willing to use more than 2GB of RAM,
165 or having a 64bit-only capable PA-RISC machine should say Y here.
167 Since there is no 64bit userland on PA-RISC, there is no point to
168 enable this option otherwise. The 64bit kernel is significantly bigger
169 and slower than the 32bit one.
172 prompt "Kernel page size"
173 default PARISC_PAGE_SIZE_4KB if !64BIT
174 default PARISC_PAGE_SIZE_4KB if 64BIT
175 # default PARISC_PAGE_SIZE_16KB if 64BIT
177 config PARISC_PAGE_SIZE_4KB
180 This lets you select the page size of the kernel. For best
181 performance, a page size of 16KB is recommended. For best
182 compatibility with 32bit applications, a page size of 4KB should be
183 selected (the vast majority of 32bit binaries work perfectly fine
184 with a larger page size).
186 4KB For best 32bit compatibility
187 16KB For best performance
188 64KB For best performance, might give more overhead.
190 If you don't know what to do, choose 4KB.

203 bool "Symmetric multi-processing support"
204 select USE_GENERIC_SMP_HELPERS
206 This enables support for systems with more than one CPU. If you have
207 a system with only one CPU, like most personal computers, say N. If
208 you have a system with more than one CPU, say Y.
210 If you say N here, the kernel will run on single and multiprocessor
211 machines, but will use only one CPU of a multiprocessor machine. If
212 you say Y here, the kernel will run on many, but not all,
213 singleprocessor machines. On a singleprocessor machine, the kernel
214 will run faster if you say N here.
216 See also <file:Documentation/nmi_watchdog.txt> and the SMP-HOWTO
217 available at <http://www.tldp.org/docs.html#howto>.
219 If you don't know what to do here, say N.
