351 can simulate a MIPS32 4Kc system. This patch adds support for the
352 system architecture that currently is being simulated by Qemu. It
353 will eventually be removed again when Qemu has the capability to
354 simulate actual MIPS hardware platforms. More information on Qemu
355 can be found at http://www.linux-mips.org/wiki/Qemu.

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

1404 SMTC pseudo-interrupts between TCs are deferred and queued
1405 if the target TC is interrupt-inhibited (IXMT). In the first
1406 SMTC prototypes, these queued IPIs were serviced on return
1407 to user mode, or on entry into the kernel idle loop. The
1408 INSTANT_REPLAY option dispatches them as part of local_irq_restore()

Linus Torvalds1da177e2005-04-16 15:20:36 -07001615 This enables support for systems with more than one CPU. If you have
1616 a system with only one CPU, like most personal computers, say N. If
1617 you have a system with more than one CPU, say Y.
1618
1619 If you say N here, the kernel will run on single and multiprocessor
1620 machines, but will use only one CPU of a multiprocessor machine. If
1621 you say Y here, the kernel will run on many, but not all,
1622 singleprocessor machines. On a singleprocessor machine, the kernel
1623 will run faster if you say N here.
1624
1625 People using multiprocessor machines who say Y here should also say
1626 Y to "Enhanced Real Time Clock Support", below.
