6 mainmenu "Linux/PA-RISC Kernel Configuration"
11 The PA-RISC microprocessor is designed by Hewlett-Packard and used
12 in many of their workstations & servers (HP9000 700 and 800 series,
13 and later HP3000 series). The PA-RISC Linux project home page is
14 at <http://www.parisc-linux.org/>.

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

155 Enable this if you want to support 64bit kernel on PA-RISC platform.
157 At the moment, only people willing to use more than 2GB of RAM,
158 or having a 64bit-only capable PA-RISC machine should say Y here.
160 Since there is no 64bit userland on PA-RISC, there is no point to
161 enable this option otherwise. The 64bit kernel is significantly bigger
162 and slower than the 32bit one.
165 prompt "Kernel page size"
166 default PARISC_PAGE_SIZE_4KB if !64BIT
167 default PARISC_PAGE_SIZE_4KB if 64BIT
168 # default PARISC_PAGE_SIZE_16KB if 64BIT
170 config PARISC_PAGE_SIZE_4KB
173 This lets you select the page size of the kernel. For best
174 performance, a page size of 16KB is recommended. For best
175 compatibility with 32bit applications, a page size of 4KB should be
176 selected (the vast majority of 32bit binaries work perfectly fine
177 with a larger page size).
179 4KB For best 32bit compatibility
180 16KB For best performance
181 64KB For best performance, might give more overhead.
183 If you don't know what to do, choose 4KB.

186 bool "16KB (EXPERIMENTAL)"

189 config PARISC_PAGE_SIZE_64KB
190 bool "64KB (EXPERIMENTAL)"
191 depends on PA8X00 && EXPERIMENTAL
196 bool "Symmetric multi-processing support"
198 This enables support for systems with more than one CPU. If you have
199 a system with only one CPU, like most personal computers, say N. If
200 you have a system with more than one CPU, say Y.
202 If you say N here, the kernel will run on single and multiprocessor
203 machines, but will use only one CPU of a multiprocessor machine. If
204 you say Y here, the kernel will run on many, but not all,
205 singleprocessor machines. On a singleprocessor machine, the kernel
206 will run faster if you say N here.
