1291 Please make sure to pick the right CPU type. Linux/MIPS is not
1292 designed to be generic, i.e. Kernels compiled for R3000 CPUs will
1293 *not* work on R4000 machines and vice versa. However, since most
1294 of the supported machines have an R4000 (or similar) CPU, R4x00
1295 might be a safe bet. If the resulting kernel does not work,
1296 try to recompile with R3000.

1518 Loongson 2F01 / 2F02 processors have the NOP & JUMP issues which
1519 require workarounds. Without workarounds the system may hang
1520 unexpectedly. For more information please refer to the gas
1521 -mfix-loongson2f-nop and -mfix-loongson2f-jump options.
1522
1523 Loongson 2F03 and later have fixed these issues and no workarounds
1524 are needed. The workarounds have no significant side effect on them
1525 but may decrease the performance of the system so this option should
1526 be disabled unless the kernel is intended to be run on 2F01 or 2F02
1527 systems.

Ralf Baechle25f12b32010-09-16 11:40:41 +01001869 This is a kernel model which is known a VSMP but lately has been
1870 marketesed into SMVP.
1871 Virtual SMP uses the processor's VPEs to implement virtual
1872 processors. In currently available configuration of the 34K processor
1873 this allows for a dual processor. Both processors will share the same
1874 primary caches; each will obtain the half of the TLB for it's own
1875 exclusive use. For a layman this model can be described as similar to
1876 what Intel calls Hyperthreading.

1893 This is a kernel model which is known a SMTC or lately has been
1894 marketesed into SMVP.
Ralf Baechle25f12b32010-09-16 11:40:41 +01001895 is presenting the available TC's of the core as processors to Linux.
1896 On currently available 34K processors this means a Linux system will
1897 see up to 5 processors. The implementation of the SMTC kernel differs
1898 significantly from VSMP and cannot efficiently coexist in the same
1899 kernel binary so the choice between VSMP and SMTC is a compile time
1900 decision.

2294 help
2295 kexec is a system call that implements the ability to shutdown your
2296 current kernel, and to start another kernel. It is like a reboot
David Sterba3dde6ad2007-05-09 07:12:20 +02002297 but it is independent of the system firmware. And like a reboot
Atsushi Nemotoea6e9422007-01-16 23:29:11 +09002298 you can start any kernel with it, not just Linux.
2299
Matt LaPlante01dd2fb2007-10-20 01:34:40 +02002300 The name comes from the similarity to the exec system call.
Atsushi Nemotoea6e9422007-01-16 23:29:11 +09002301
2302 It is an ongoing process to be certain the hardware in a machine
2303 is properly shutdown, so do not be surprised if this code does not
2304 initially work for you. It may help to enable device hotplugging
2305 support. As of this writing the exact hardware interface is
2306 strongly in flux, so no good recommendation can be made.

2312 help
2313 This kernel feature is useful for number crunching applications
2314 that may need to compute untrusted bytecode during their
2315 execution. By using pipes or other transports made available to
2316 the process as file descriptors supporting the read/write
2317 syscalls, it's possible to isolate those applications in
2318 their own address space using seccomp. Once seccomp is
2319 enabled via /proc/<pid>/seccomp, it cannot be disabled
2320 and the task is only allowed to execute a few safe syscalls
2321 defined by each seccomp mode.

2388 The EISA bus provided some of the features of the IBM MicroChannel
2389 bus while maintaining backward compatibility with cards made for
2390 the older ISA bus. The EISA bus saw limited use between 1988 and
