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.

928 Choose this option to build a kernel for release 1 or later of the
929 MIPS64 architecture. Many modern embedded systems with a 64-bit
930 MIPS processor are based on a MIPS64 processor. If you know the
931 specific type of processor in your system, choose those that one
932 otherwise CPU_MIPS64_R1 is a safe bet for any MIPS64 system.
Ralf Baechle1e5f1ca2005-07-12 14:51:22 +0000933 Release 2 of the MIPS64 architecture is available since several
934 years so chances are you even have a MIPS64 Release 2 processor
935 in which case you should choose CPU_MIPS64_R2 instead for better
936 performance.

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

1374 if the target TC is interrupt-inhibited (IXMT). In the first
1375 SMTC prototypes, these queued IPIs were serviced on return
1376 to user mode, or on entry into the kernel idle loop. The
