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/>.

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

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