81 If you have one of the following DECstation Models you definitely
82 want to choose R4xx0 for the CPU Type:
83
84 DECstation 5000/50
85 DECstation 5000/150
86 DECstation 5000/260
87 DECsystem 5900/260

Ralf Baechle5e83d432005-10-29 19:32:41 +0100317 Qemu is a software emulator which among other architectures also
318 can simulate a MIPS32 4Kc system. This patch adds support for the
319 system architecture that currently is being simulated by Qemu. It
320 will eventually be removed again when Qemu has the capability to
321 simulate actual MIPS hardware platforms. More information on Qemu
322 can be found at http://www.linux-mips.org/wiki/Qemu.

924 Choose this option to build a kernel for release 1 or later of the
925 MIPS64 architecture. Many modern embedded systems with a 64-bit
926 MIPS processor are based on a MIPS64 processor. If you know the
927 specific type of processor in your system, choose those that one
928 otherwise CPU_MIPS64_R1 is a safe bet for any MIPS64 system.
Ralf Baechle1e5f1ca2005-07-12 14:51:22 +0000929 Release 2 of the MIPS64 architecture is available since several
930 years so chances are you even have a MIPS64 Release 2 processor
931 in which case you should choose CPU_MIPS64_R2 instead for better
932 performance.

956 Please make sure to pick the right CPU type. Linux/MIPS is not
957 designed to be generic, i.e. Kernels compiled for R3000 CPUs will
958 *not* work on R4000 machines and vice versa. However, since most
959 of the supported machines have an R4000 (or similar) CPU, R4x00
960 might be a safe bet. If the resulting kernel does not work,
961 try to recompile with R3000.

1370 if the target TC is interrupt-inhibited (IXMT). In the first
