1031 Please make sure to pick the right CPU type. Linux/MIPS is not
1032 designed to be generic, i.e. Kernels compiled for R3000 CPUs will
1033 *not* work on R4000 machines and vice versa. However, since most
1034 of the supported machines have an R4000 (or similar) CPU, R4x00
1035 might be a safe bet. If the resulting kernel does not work,
1036 try to recompile with R3000.

1457 help
1458 SMTC pseudo-interrupts between TCs are deferred and queued
1459 if the target TC is interrupt-inhibited (IXMT). In the first
1460 SMTC prototypes, these queued IPIs were serviced on return
1461 to user mode, or on entry into the kernel idle loop. The
1462 INSTANT_REPLAY option dispatches them as part of local_irq_restore()
1463 processing, which adds runtime overhead (hence the option to turn
1464 it off), but ensures that IPIs are handled promptly even under
1465 heavy I/O interrupt load.

1472 To support multiple TC microthreads acting as "CPUs" within
1473 a VPE, VPE-wide interrupt mask bits must be specially manipulated
1474 during interrupt handling. To support legacy drivers and interrupt
1475 controller management code, SMTC has a "backstop" to track and
1476 if necessary restore the interrupt mask. This has some performance
1477 impact on interrupt service overhead. Disable it only if you know

1927 The EISA bus provided some of the features of the IBM MicroChannel
1928 bus while maintaining backward compatibility with cards made for
1929 the older ISA bus. The EISA bus saw limited use between 1988 and
1930 1995 when it was made obsolete by the PCI bus.
1931
1932 Say Y here if you are building a kernel for an EISA-based machine.
1933
1934 Otherwise, say N.
