1271 Please make sure to pick the right CPU type. Linux/MIPS is not
1272 designed to be generic, i.e. Kernels compiled for R3000 CPUs will
1273 *not* work on R4000 machines and vice versa. However, since most
1274 of the supported machines have an R4000 (or similar) CPU, R4x00
1275 might be a safe bet. If the resulting kernel does not work,
1276 try to recompile with R3000.

1835 marketesed into SMVP.
1836 Virtual SMP uses the processor's VPEs to implement virtual
1837 processors. In currently available configuration of the 34K processor
1838 this allows for a dual processor. Both processors will share the same
1839 primary caches; each will obtain the half of the TLB for it's own
1840 exclusive use. For a layman this model can be described as similar to
1841 what Intel calls Hyperthreading.

1910 To support multiple TC microthreads acting as "CPUs" within
1911 a VPE, VPE-wide interrupt mask bits must be specially manipulated
1912 during interrupt handling. To support legacy drivers and interrupt
1913 controller management code, SMTC has a "backstop" to track and
1914 if necessary restore the interrupt mask. This has some performance

2282 It is an ongoing process to be certain the hardware in a machine
2283 is properly shutdown, so do not be surprised if this code does not
2284 initially work for you. It may help to enable device hotplugging
2285 support. As of this writing the exact hardware interface is
2286 strongly in flux, so no good recommendation can be made.

2293 This kernel feature is useful for number crunching applications
2294 that may need to compute untrusted bytecode during their
2295 execution. By using pipes or other transports made available to
2296 the process as file descriptors supporting the read/write
2297 syscalls, it's possible to isolate those applications in
2298 their own address space using seccomp. Once seccomp is
2299 enabled via /proc/<pid>/seccomp, it cannot be disabled
2300 and the task is only allowed to execute a few safe syscalls
2301 defined by each seccomp mode.
