80 If you have one of the following DECstation Models you definitely
81 want to choose R4xx0 for the CPU Type:

Ralf Baechle5e83d432005-10-29 19:32:41 +0100316 Qemu is a software emulator which among other architectures also
317 can simulate a MIPS32 4Kc system. This patch adds support for the
318 system architecture that currently is being simulated by Qemu. It
319 will eventually be removed again when Qemu has the capability to
320 simulate actual MIPS hardware platforms. More information on Qemu
321 can be found at http://www.linux-mips.org/wiki/Qemu.

927 Choose this option to build a kernel for release 1 or later of the
928 MIPS64 architecture. Many modern embedded systems with a 64-bit
929 MIPS processor are based on a MIPS64 processor. If you know the
930 specific type of processor in your system, choose those that one
931 otherwise CPU_MIPS64_R1 is a safe bet for any MIPS64 system.
Ralf Baechle1e5f1ca2005-07-12 14:51:22 +0000932 Release 2 of the MIPS64 architecture is available since several
933 years so chances are you even have a MIPS64 Release 2 processor
934 in which case you should choose CPU_MIPS64_R2 instead for better
935 performance.

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