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/>.

78 menu "Processor type and features"
81 prompt "Processor type"
87 This is the processor type of your CPU. This information is
88 used for optimizing purposes. In order to compile a kernel
89 that can run on all 32-bit PA CPUs (albeit not optimally fast),
90 you can specify "PA7000" here.
92 Specifying "PA8000" here will allow you to select a 64-bit kernel
93 which is required on some machines.
98 Select this option for the PCX-L processor, as used in the
99 712, 715/64, 715/80, 715/100, 715/100XC, 725/100, 743, 748,
100 D200, D210, D300, D310 and E-class
105 Select this option for the PCX-T' processor, as used in the
106 C100, C110, J100, J110, J210XC, D250, D260, D350, D360,
107 K100, K200, K210, K220, K400, K410 and K420
112 Select this option for the PCX-L2 processor, as used in the
113 744, A180, B132L, B160L, B180L, C132L, C160L, C180L,
114 D220, D230, D320 and D330.
119 Select this option for PCX-U to PCX-W2 processors.

141 Enable this if you want to support 64bit kernel on PA-RISC platform.
143 At the moment, only people willing to use more than 2GB of RAM,
144 or having a 64bit-only capable PA-RISC machine should say Y here.
146 Since there is no 64bit userland on PA-RISC, there is no point to
147 enable this option otherwise. The 64bit kernel is significantly bigger
148 and slower than the 32bit one.
151 prompt "Kernel page size"
152 default PARISC_PAGE_SIZE_4KB if !64BIT
153 default PARISC_PAGE_SIZE_4KB if 64BIT
154 # default PARISC_PAGE_SIZE_16KB if 64BIT
156 config PARISC_PAGE_SIZE_4KB
159 This lets you select the page size of the kernel. For best
160 performance, a page size of 16KB is recommended. For best
161 compatibility with 32bit applications, a page size of 4KB should be
162 selected (the vast majority of 32bit binaries work perfectly fine
163 with a larger page size).
165 4KB For best 32bit compatibility
166 16KB For best performance
167 64KB For best performance, might give more overhead.
169 If you don't know what to do, choose 4KB.
171 config PARISC_PAGE_SIZE_16KB
172 bool "16KB (EXPERIMENTAL)"
173 depends on PA8X00 && EXPERIMENTAL
175 config PARISC_PAGE_SIZE_64KB
176 bool "64KB (EXPERIMENTAL)"
177 depends on PA8X00 && EXPERIMENTAL
182 bool "Symmetric multi-processing support"
184 This enables support for systems with more than one CPU. If you have
185 a system with only one CPU, like most personal computers, say N. If
186 you have a system with more than one CPU, say Y.
188 If you say N here, the kernel will run on single and multiprocessor
189 machines, but will use only one CPU of a multiprocessor machine. If
190 you say Y here, the kernel will run on many, but not all,
191 singleprocessor machines. On a singleprocessor machine, the kernel
192 will run faster if you say N here.
