1014 Please make sure to pick the right CPU type. Linux/MIPS is not
1015 designed to be generic, i.e. Kernels compiled for R3000 CPUs will
1016 *not* work on R4000 machines and vice versa. However, since most
1017 of the supported machines have an R4000 (or similar) CPU, R4x00
1018 might be a safe bet. If the resulting kernel does not work,
1019 try to recompile with R3000.

1440 help
1441 SMTC pseudo-interrupts between TCs are deferred and queued
1442 if the target TC is interrupt-inhibited (IXMT). In the first
1443 SMTC prototypes, these queued IPIs were serviced on return
1444 to user mode, or on entry into the kernel idle loop. The
1445 INSTANT_REPLAY option dispatches them as part of local_irq_restore()
1446 processing, which adds runtime overhead (hence the option to turn
1447 it off), but ensures that IPIs are handled promptly even under
1448 heavy I/O interrupt load.

1454 help
1455 To support multiple TC microthreads acting as "CPUs" within
1456 a VPE, VPE-wide interrupt mask bits must be specially manipulated
1457 during interrupt handling. To support legacy drivers and interrupt
1458 controller management code, SMTC has a "backstop" to track and
1459 if necessary restore the interrupt mask. This has some performance
1460 impact on interrupt service overhead. Disable it only if you know

1960 Select this option if you want Linux/MIPS 32-bit binary
1961 compatibility. Since all software available for Linux/MIPS is
1962 currently 32-bit you should say Y here.

1978 Select this option if you want to run o32 binaries. These are pure
1979 32-bit binaries as used by the 32-bit Linux/MIPS port. Most of
1980 existing binaries are in this format.

1989 64-bit binaries using 32-bit quantities for addressing and certain
