1292 Please make sure to pick the right CPU type. Linux/MIPS is not
1293 designed to be generic, i.e. Kernels compiled for R3000 CPUs will
1294 *not* work on R4000 machines and vice versa. However, since most
1295 of the supported machines have an R4000 (or similar) CPU, R4x00
1296 might be a safe bet. If the resulting kernel does not work,
1297 try to recompile with R3000.

1516 Loongson 2F01 / 2F02 processors have the NOP & JUMP issues which
1517 require workarounds. Without workarounds the system may hang
1518 unexpectedly. For more information please refer to the gas
1519 -mfix-loongson2f-nop and -mfix-loongson2f-jump options.
1520
1521 Loongson 2F03 and later have fixed these issues and no workarounds
1522 are needed. The workarounds have no significant side effect on them
1523 but may decrease the performance of the system so this option should
1524 be disabled unless the kernel is intended to be run on 2F01 or 2F02
1525 systems.
1526
1527 If unsure, please say Y.

Ralf Baechle25f12b32010-09-16 11:40:41 +01001865 This is a kernel model which is known a VSMP but lately has been
1866 marketesed into SMVP.
1867 Virtual SMP uses the processor's VPEs to implement virtual
1868 processors. In currently available configuration of the 34K processor
1869 this allows for a dual processor. Both processors will share the same
1870 primary caches; each will obtain the half of the TLB for it's own
1871 exclusive use. For a layman this model can be described as similar to
1872 what Intel calls Hyperthreading.

1889 This is a kernel model which is known a SMTC or lately has been
1890 marketesed into SMVP.
Ralf Baechle25f12b32010-09-16 11:40:41 +01001891 is presenting the available TC's of the core as processors to Linux.
1892 On currently available 34K processors this means a Linux system will
1893 see up to 5 processors. The implementation of the SMTC kernel differs
1894 significantly from VSMP and cannot efficiently coexist in the same
1895 kernel binary so the choice between VSMP and SMTC is a compile time
1896 decision.

2296 kexec is a system call that implements the ability to shutdown your
2297 current kernel, and to start another kernel. It is like a reboot
David Sterba3dde6ad2007-05-09 07:12:20 +02002298 but it is independent of the system firmware. And like a reboot
Atsushi Nemotoea6e9422007-01-16 23:29:11 +09002299 you can start any kernel with it, not just Linux.
2300
Matt LaPlante01dd2fb2007-10-20 01:34:40 +02002301 The name comes from the similarity to the exec system call.
Atsushi Nemotoea6e9422007-01-16 23:29:11 +09002302
2303 It is an ongoing process to be certain the hardware in a machine
2304 is properly shutdown, so do not be surprised if this code does not
2305 initially work for you. It may help to enable device hotplugging
2306 support. As of this writing the exact hardware interface is

2314 This kernel feature is useful for number crunching applications
2315 that may need to compute untrusted bytecode during their
2316 execution. By using pipes or other transports made available to
2317 the process as file descriptors supporting the read/write
2318 syscalls, it's possible to isolate those applications in
2319 their own address space using seccomp. Once seccomp is
2320 enabled via /proc/<pid>/seccomp, it cannot be disabled
2321 and the task is only allowed to execute a few safe syscalls
2322 defined by each seccomp mode.
