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/>.

90 menu "Processor type and features"
93 prompt "Processor type"
99 This is the processor type of your CPU. This information is
100 used for optimizing purposes. In order to compile a kernel
101 that can run on all 32-bit PA CPUs (albeit not optimally fast),
102 you can specify "PA7000" here.
104 Specifying "PA8000" here will allow you to select a 64-bit kernel
105 which is required on some machines.
110 Select this option for the PCX-L processor, as used in the
111 712, 715/64, 715/80, 715/100, 715/100XC, 725/100, 743, 748,
112 D200, D210, D300, D310 and E-class
117 Select this option for the PCX-T' processor, as used in the
118 C100, C110, J100, J110, J210XC, D250, D260, D350, D360,
119 K100, K200, K210, K220, K400, K410 and K420
124 Select this option for the PCX-L2 processor, as used in the
125 744, A180, B132L, B160L, B180L, C132L, C160L, C180L,
126 D220, D230, D320 and D330.
131 Select this option for PCX-U to PCX-W2 processors.
135 # Define implied options from the CPU selection here

147 depends on PA8X00 || PA7200
153 Enable this if you want to support 64bit kernel on PA-RISC platform.
155 At the moment, only people willing to use more than 2GB of RAM,
156 or having a 64bit-only capable PA-RISC machine should say Y here.
158 Since there is no 64bit userland on PA-RISC, there is no point to
159 enable this option otherwise. The 64bit kernel is significantly bigger
160 and slower than the 32bit one.
163 prompt "Kernel page size"
164 default PARISC_PAGE_SIZE_4KB if !64BIT
165 default PARISC_PAGE_SIZE_4KB if 64BIT
166 # default PARISC_PAGE_SIZE_16KB if 64BIT
168 config PARISC_PAGE_SIZE_4KB
171 This lets you select the page size of the kernel. For best
172 performance, a page size of 16KB is recommended. For best
173 compatibility with 32bit applications, a page size of 4KB should be
174 selected (the vast majority of 32bit binaries work perfectly fine
175 with a larger page size).
177 4KB For best 32bit compatibility
178 16KB For best performance
179 64KB For best performance, might give more overhead.
181 If you don't know what to do, choose 4KB.
183 config PARISC_PAGE_SIZE_16KB
184 bool "16KB (EXPERIMENTAL)"
185 depends on PA8X00 && EXPERIMENTAL
187 config PARISC_PAGE_SIZE_64KB
188 bool "64KB (EXPERIMENTAL)"
189 depends on PA8X00 && EXPERIMENTAL
194 bool "Symmetric multi-processing support"
196 This enables support for systems with more than one CPU. If you have
197 a system with only one CPU, like most personal computers, say N. If
198 you have a system with more than one CPU, say Y.
200 If you say N here, the kernel will run on single and multiprocessor
201 machines, but will use only one CPU of a multiprocessor machine. If
202 you say Y here, the kernel will run on many, but not all,
203 singleprocessor machines. On a singleprocessor machine, the kernel
204 will run faster if you say N here.
