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/>.

73 menu "Processor type and features"
76 prompt "Processor type"
82 This is the processor type of your CPU. This information is
83 used for optimizing purposes. In order to compile a kernel
84 that can run on all 32-bit PA CPUs (albeit not optimally fast),
85 you can specify "PA7000" here.
87 Specifying "PA8000" here will allow you to select a 64-bit kernel
88 which is required on some machines.
93 Select this option for the PCX-L processor, as used in the
94 712, 715/64, 715/80, 715/100, 715/100XC, 725/100, 743, 748,
95 D200, D210, D300, D310 and E-class
100 Select this option for the PCX-T' processor, as used in the
101 C100, C110, J100, J110, J210XC, D250, D260, D350, D360,
102 K100, K200, K210, K220, K400, K410 and K420
107 Select this option for the PCX-L2 processor, as used in the
108 744, A180, B132L, B160L, B180L, C132L, C160L, C180L,
109 D220, D230, D320 and D330.
114 Select this option for PCX-U to PCX-W2 processors.

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

190 <file:Documentation/nmi_watchdog.txt> and the SMP-HOWTO available
191 at <http://www.tldp.org/docs.html#howto>.
193 If you don't know what to do here, say N.
