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/>.

69 menu "Processor type and features"
72 prompt "Processor type"
78 This is the processor type of your CPU. This information is
79 used for optimizing purposes. In order to compile a kernel
80 that can run on all 32-bit PA CPUs (albeit not optimally fast),
81 you can specify "PA7000" here.
83 Specifying "PA8000" here will allow you to select a 64-bit kernel
84 which is required on some machines.
89 Select this option for the PCX-L processor, as used in the
90 712, 715/64, 715/80, 715/100, 715/100XC, 725/100, 743, 748,
91 D200, D210, D300, D310 and E-class
96 Select this option for the PCX-T' processor, as used in the
97 C100, C110, J100, J110, J210XC, D250, D260, D350, D360,
98 K100, K200, K210, K220, K400, K410 and K420
103 Select this option for the PCX-L2 processor, as used in the
104 744, A180, B132L, B160L, B180L, C132L, C160L, C180L,
105 D220, D230, D320 and D330.
110 Select this option for PCX-U to PCX-W2 processors.
114 # Define implied options from the CPU selection here
122 depends on PA7000 || PA7100LC || PA7200 || PA7300LC
132 Enable this if you want to support 64bit kernel on PA-RISC platform.
134 At the moment, only people willing to use more than 2GB of RAM,
135 or having a 64bit-only capable PA-RISC machine should say Y here.
137 Since there is no 64bit userland on PA-RISC, there is no point to
138 enable this option otherwise. The 64bit kernel is significantly bigger
139 and slower than the 32bit one.
142 prompt "Kernel page size"
143 default PARISC_PAGE_SIZE_4KB if !64BIT
144 default PARISC_PAGE_SIZE_4KB if 64BIT
145 # default PARISC_PAGE_SIZE_16KB if 64BIT
147 config PARISC_PAGE_SIZE_4KB
150 This lets you select the page size of the kernel. For best
151 performance, a page size of 16KB is recommended. For best
152 compatibility with 32bit applications, a page size of 4KB should be
153 selected (the vast majority of 32bit binaries work perfectly fine
154 with a larger page size).
156 4KB For best 32bit compatibility
157 16KB For best performance
158 64KB For best performance, might give more overhead.
160 If you don't know what to do, choose 4KB.
162 config PARISC_PAGE_SIZE_16KB
163 bool "16KB (EXPERIMENTAL)"
164 depends on PA8X00 && EXPERIMENTAL
166 config PARISC_PAGE_SIZE_64KB
167 bool "64KB (EXPERIMENTAL)"
168 depends on PA8X00 && EXPERIMENTAL
173 bool "Symmetric multi-processing support"
175 This enables support for systems with more than one CPU. If you have
176 a system with only one CPU, like most personal computers, say N. If
177 you have a system with more than one CPU, say Y.
179 If you say N here, the kernel will run on single and multiprocessor
180 machines, but will use only one CPU of a multiprocessor machine. If
181 you say Y here, the kernel will run on many, but not all,
182 singleprocessor machines. On a singleprocessor machine, the kernel
183 will run faster if you say N here.

186 <file:Documentation/nmi_watchdog.txt> and the SMP-HOWTO available

189 If you don't know what to do here, say N.
