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 +0100318 Qemu is a software emulator which among other architectures also
319 can simulate a MIPS32 4Kc system. This patch adds support for the
320 system architecture that currently is being simulated by Qemu. It
321 will eventually be removed again when Qemu has the capability to
322 simulate actual MIPS hardware platforms. More information on Qemu
323 can be found at http://www.linux-mips.org/wiki/Qemu.

921 Choose this option to build a kernel for release 1 or later of the
922 MIPS64 architecture. Many modern embedded systems with a 64-bit
923 MIPS processor are based on a MIPS64 processor. If you know the
924 specific type of processor in your system, choose those that one
925 otherwise CPU_MIPS64_R1 is a safe bet for any MIPS64 system.
Ralf Baechle1e5f1ca2005-07-12 14:51:22 +0000926 Release 2 of the MIPS64 architecture is available since several
927 years so chances are you even have a MIPS64 Release 2 processor
928 in which case you should choose CPU_MIPS64_R2 instead for better
929 performance.

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

1367 if the target TC is interrupt-inhibited (IXMT). In the first
1368 SMTC prototypes, these queued IPIs were serviced on return
1369 to user mode, or on entry into the kernel idle loop. The
