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

914 Choose this option to build a kernel for release 1 or later of the
915 MIPS64 architecture. Many modern embedded systems with a 64-bit
916 MIPS processor are based on a MIPS64 processor. If you know the
917 specific type of processor in your system, choose those that one
918 otherwise CPU_MIPS64_R1 is a safe bet for any MIPS64 system.
Ralf Baechle1e5f1ca2005-07-12 14:51:22 +0000919 Release 2 of the MIPS64 architecture is available since several
920 years so chances are you even have a MIPS64 Release 2 processor
921 in which case you should choose CPU_MIPS64_R2 instead for better
922 performance.

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

1359 SMTC pseudo-interrupts between TCs are deferred and queued
1360 if the target TC is interrupt-inhibited (IXMT). In the first
1361 SMTC prototypes, these queued IPIs were serviced on return
1362 to user mode, or on entry into the kernel idle loop. The
1363 INSTANT_REPLAY option dispatches them as part of local_irq_restore()
1364 processing, which adds runtime overhead (hence the option to turn
1365 it off), but ensures that IPIs are handled promptly even under
