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.

923 Choose this option to build a kernel for release 1 or later of the
924 MIPS64 architecture. Many modern embedded systems with a 64-bit
925 MIPS processor are based on a MIPS64 processor. If you know the
926 specific type of processor in your system, choose those that one
927 otherwise CPU_MIPS64_R1 is a safe bet for any MIPS64 system.
Ralf Baechle1e5f1ca2005-07-12 14:51:22 +0000928 Release 2 of the MIPS64 architecture is available since several
929 years so chances are you even have a MIPS64 Release 2 processor
930 in which case you should choose CPU_MIPS64_R2 instead for better
931 performance.

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

1369 if the target TC is interrupt-inhibited (IXMT). In the first
1370 SMTC prototypes, these queued IPIs were serviced on return
1371 to user mode, or on entry into the kernel idle loop. The
1372 INSTANT_REPLAY option dispatches them as part of local_irq_restore()

David Sterba3dde6ad2007-05-09 07:12:20 +02001720 but it is independent of the system firmware. And like a reboot
