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

357 can simulate a MIPS32 4Kc system. This patch adds support for the
358 system architecture that currently is being simulated by Qemu. It
359 will eventually be removed again when Qemu has the capability to
360 simulate actual MIPS hardware platforms. More information on Qemu

996 Please make sure to pick the right CPU type. Linux/MIPS is not
997 designed to be generic, i.e. Kernels compiled for R3000 CPUs will
998 *not* work on R4000 machines and vice versa. However, since most
999 of the supported machines have an R4000 (or similar) CPU, R4x00
1000 might be a safe bet. If the resulting kernel does not work,
1001 try to recompile with R3000.

1409 SMTC pseudo-interrupts between TCs are deferred and queued
1410 if the target TC is interrupt-inhibited (IXMT). In the first
1411 SMTC prototypes, these queued IPIs were serviced on return
1412 to user mode, or on entry into the kernel idle loop. The
1413 INSTANT_REPLAY option dispatches them as part of local_irq_restore()
1414 processing, which adds runtime overhead (hence the option to turn
1415 it off), but ensures that IPIs are handled promptly even under
