1273 Please make sure to pick the right CPU type. Linux/MIPS is not
1274 designed to be generic, i.e. Kernels compiled for R3000 CPUs will
1275 *not* work on R4000 machines and vice versa. However, since most
1276 of the supported machines have an R4000 (or similar) CPU, R4x00
1277 might be a safe bet. If the resulting kernel does not work,
1278 try to recompile with R3000.

1837 marketesed into SMVP.
1838 Virtual SMP uses the processor's VPEs to implement virtual
1839 processors. In currently available configuration of the 34K processor
1840 this allows for a dual processor. Both processors will share the same
1841 primary caches; each will obtain the half of the TLB for it's own
1842 exclusive use. For a layman this model can be described as similar to
1843 what Intel calls Hyperthreading.

1912 To support multiple TC microthreads acting as "CPUs" within
1913 a VPE, VPE-wide interrupt mask bits must be specially manipulated
1914 during interrupt handling. To support legacy drivers and interrupt
1915 controller management code, SMTC has a "backstop" to track and
1916 if necessary restore the interrupt mask. This has some performance

2284 It is an ongoing process to be certain the hardware in a machine
2285 is properly shutdown, so do not be surprised if this code does not
2286 initially work for you. It may help to enable device hotplugging
2287 support. As of this writing the exact hardware interface is
2288 strongly in flux, so no good recommendation can be made.

2295 This kernel feature is useful for number crunching applications
2296 that may need to compute untrusted bytecode during their
2297 execution. By using pipes or other transports made available to
2298 the process as file descriptors supporting the read/write
2299 syscalls, it's possible to isolate those applications in
2300 their own address space using seccomp. Once seccomp is
2301 enabled via /proc/<pid>/seccomp, it cannot be disabled
2302 and the task is only allowed to execute a few safe syscalls
2303 defined by each seccomp mode.

2367 The EISA bus provided some of the features of the IBM MicroChannel
