332 can simulate a MIPS32 4Kc system. This patch adds support for the
333 system architecture that currently is being simulated by Qemu. It
334 will eventually be removed again when Qemu has the capability to
335 simulate actual MIPS hardware platforms. More information on Qemu
336 can be found at http://www.linux-mips.org/wiki/Qemu.

932 Choose this option to build a kernel for release 1 or later of the
933 MIPS64 architecture. Many modern embedded systems with a 64-bit
934 MIPS processor are based on a MIPS64 processor. If you know the

Ralf Baechle1e5f1ca2005-07-12 14:51:22 +0000937 Release 2 of the MIPS64 architecture is available since several

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

1378 if the target TC is interrupt-inhibited (IXMT). In the first
1379 SMTC prototypes, these queued IPIs were serviced on return

1740 kexec is a system call that implements the ability to shutdown your

David Sterba3dde6ad2007-05-09 07:12:20 +02001742 but it is independent of the system firmware. And like a reboot

1745 The name comes from the similiarity to the exec system call.

1747 It is an ongoing process to be certain the hardware in a machine
1748 is properly shutdown, so do not be surprised if this code does not
1749 initially work for you. It may help to enable device hotplugging
