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/>.

59 menu "Processor type and features"
62 prompt "Processor type"
68 This is the processor type of your CPU. This information is
69 used for optimizing purposes. In order to compile a kernel
70 that can run on all 32-bit PA CPUs (albeit not optimally fast),
71 you can specify "PA7000" here.
73 Specifying "PA8000" here will allow you to select a 64-bit kernel
74 which is required on some machines.
79 Select this option for the PCX-L processor, as used in the
80 712, 715/64, 715/80, 715/100, 715/100XC, 725/100, 743, 748,
81 D200, D210, D300, D310 and E-class
86 Select this option for the PCX-T' processor, as used in the
87 C100, C110, J100, J110, J210XC, D250, D260, D350, D360,
88 K100, K200, K210, K220, K400, K410 and K420
93 Select this option for the PCX-L2 processor, as used in the
94 744, A180, B132L, B160L, B180L, C132L, C160L, C180L,
95 D220, D230, D320 and D330.
100 Select this option for PCX-U to PCX-W2 processors.
104 # Define implied options from the CPU selection here
112 depends on PA7000 || PA7100LC || PA7200 || PA7300LC
122 Enable this if you want to support 64bit kernel on PA-RISC platform.
124 At the moment, only people willing to use more than 2GB of RAM,
125 or having a 64bit-only capable PA-RISC machine should say Y here.
127 Since there is no 64bit userland on PA-RISC, there is no point to
128 enable this option otherwise. The 64bit kernel is significantly bigger
129 and slower than the 32bit one.
132 bool "Symmetric multi-processing support"
134 This enables support for systems with more than one CPU. If you have
135 a system with only one CPU, like most personal computers, say N. If
136 you have a system with more than one CPU, say Y.
138 If you say N here, the kernel will run on single and multiprocessor
139 machines, but will use only one CPU of a multiprocessor machine. If
140 you say Y here, the kernel will run on many, but not all,
141 singleprocessor machines. On a singleprocessor machine, the kernel
142 will run faster if you say N here.
144 See also the <file:Documentation/smp.txt>,
145 <file:Documentation/nmi_watchdog.txt> and the SMP-HOWTO available
146 at <http://www.tldp.org/docs.html#howto>.
148 If you don't know what to do here, say N.
155 config ARCH_DISCONTIGMEM_ENABLE
156 bool "Discontiguous memory support (EXPERIMENTAL)"
157 depends on 64BIT && EXPERIMENTAL
159 Say Y to support efficient handling of discontiguous physical memory,
160 for architectures which are either NUMA (Non-Uniform Memory Access)
161 or have huge holes in the physical address space for other reasons.
162 See <file:Documentation/vm/numa> for more.
