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

998 Please make sure to pick the right CPU type. Linux/MIPS is not
999 designed to be generic, i.e. Kernels compiled for R3000 CPUs will
1000 *not* work on R4000 machines and vice versa. However, since most
1001 of the supported machines have an R4000 (or similar) CPU, R4x00
1002 might be a safe bet. If the resulting kernel does not work,
1003 try to recompile with R3000.

1411 SMTC pseudo-interrupts between TCs are deferred and queued
1412 if the target TC is interrupt-inhibited (IXMT). In the first
1413 SMTC prototypes, these queued IPIs were serviced on return
1414 to user mode, or on entry into the kernel idle loop. The
1415 INSTANT_REPLAY option dispatches them as part of local_irq_restore()
1416 processing, which adds runtime overhead (hence the option to turn
1417 it off), but ensures that IPIs are handled promptly even under

1623 a system with only one CPU, like most personal computers, say N. If
1624 you have a system with more than one CPU, say Y.
1625
1626 If you say N here, the kernel will run on single and multiprocessor
1627 machines, but will use only one CPU of a multiprocessor machine. If
1628 you say Y here, the kernel will run on many, but not all,
1629 singleprocessor machines. On a singleprocessor machine, the kernel
1630 will run faster if you say N here.
