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/>.

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

143 depends on PA8X00 || PA7200
149 Enable this if you want to support 64bit kernel on PA-RISC platform.
151 At the moment, only people willing to use more than 2GB of RAM,
152 or having a 64bit-only capable PA-RISC machine should say Y here.
154 Since there is no 64bit userland on PA-RISC, there is no point to
155 enable this option otherwise. The 64bit kernel is significantly bigger
156 and slower than the 32bit one.
159 prompt "Kernel page size"
160 default PARISC_PAGE_SIZE_4KB if !64BIT
161 default PARISC_PAGE_SIZE_4KB if 64BIT
162 # default PARISC_PAGE_SIZE_16KB if 64BIT
164 config PARISC_PAGE_SIZE_4KB
167 This lets you select the page size of the kernel. For best
168 performance, a page size of 16KB is recommended. For best
169 compatibility with 32bit applications, a page size of 4KB should be
170 selected (the vast majority of 32bit binaries work perfectly fine
171 with a larger page size).
173 4KB For best 32bit compatibility
174 16KB For best performance
175 64KB For best performance, might give more overhead.
177 If you don't know what to do, choose 4KB.
179 config PARISC_PAGE_SIZE_16KB
180 bool "16KB (EXPERIMENTAL)"
181 depends on PA8X00 && EXPERIMENTAL
183 config PARISC_PAGE_SIZE_64KB
184 bool "64KB (EXPERIMENTAL)"
185 depends on PA8X00 && EXPERIMENTAL
190 bool "Symmetric multi-processing support"
192 This enables support for systems with more than one CPU. If you have
193 a system with only one CPU, like most personal computers, say N. If
194 you have a system with more than one CPU, say Y.
196 If you say N here, the kernel will run on single and multiprocessor
197 machines, but will use only one CPU of a multiprocessor machine. If
198 you say Y here, the kernel will run on many, but not all,
199 singleprocessor machines. On a singleprocessor machine, the kernel
200 will run faster if you say N here.
