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/>.

81 menu "Processor type and features"
84 prompt "Processor type"
90 This is the processor type of your CPU. This information is
91 used for optimizing purposes. In order to compile a kernel
92 that can run on all 32-bit PA CPUs (albeit not optimally fast),
93 you can specify "PA7000" here.
95 Specifying "PA8000" here will allow you to select a 64-bit kernel
96 which is required on some machines.
101 Select this option for the PCX-L processor, as used in the
102 712, 715/64, 715/80, 715/100, 715/100XC, 725/100, 743, 748,
103 D200, D210, D300, D310 and E-class
108 Select this option for the PCX-T' processor, as used in the
109 C100, C110, J100, J110, J210XC, D250, D260, D350, D360,
110 K100, K200, K210, K220, K400, K410 and K420
115 Select this option for the PCX-L2 processor, as used in the
116 744, A180, B132L, B160L, B180L, C132L, C160L, C180L,
117 D220, D230, D320 and D330.
122 Select this option for PCX-U to PCX-W2 processors.

138 depends on PA8X00 || PA7200
144 Enable this if you want to support 64bit kernel on PA-RISC platform.
146 At the moment, only people willing to use more than 2GB of RAM,
147 or having a 64bit-only capable PA-RISC machine should say Y here.
149 Since there is no 64bit userland on PA-RISC, there is no point to
150 enable this option otherwise. The 64bit kernel is significantly bigger
151 and slower than the 32bit one.
154 prompt "Kernel page size"
155 default PARISC_PAGE_SIZE_4KB if !64BIT
156 default PARISC_PAGE_SIZE_4KB if 64BIT
157 # default PARISC_PAGE_SIZE_16KB if 64BIT
159 config PARISC_PAGE_SIZE_4KB
162 This lets you select the page size of the kernel. For best
163 performance, a page size of 16KB is recommended. For best
164 compatibility with 32bit applications, a page size of 4KB should be
165 selected (the vast majority of 32bit binaries work perfectly fine
166 with a larger page size).
168 4KB For best 32bit compatibility
169 16KB For best performance
170 64KB For best performance, might give more overhead.
172 If you don't know what to do, choose 4KB.
174 config PARISC_PAGE_SIZE_16KB
175 bool "16KB (EXPERIMENTAL)"
176 depends on PA8X00 && EXPERIMENTAL
178 config PARISC_PAGE_SIZE_64KB
179 bool "64KB (EXPERIMENTAL)"
180 depends on PA8X00 && EXPERIMENTAL
185 bool "Symmetric multi-processing support"
187 This enables support for systems with more than one CPU. If you have
188 a system with only one CPU, like most personal computers, say N. If
189 you have a system with more than one CPU, say Y.
191 If you say N here, the kernel will run on single and multiprocessor
192 machines, but will use only one CPU of a multiprocessor machine. If
193 you say Y here, the kernel will run on many, but not all,
194 singleprocessor machines. On a singleprocessor machine, the kernel
195 will run faster if you say N here.
