It is like a reboot - but it is indepedent of the system firmware. And like a reboot - you can start any kernel with it, not just Linux. - - The name comes from the similiarity to the exec system call. - - It is an ongoing process to be certain the hardware in a machine - is properly shutdown, so do not be surprised if this code does not - initially work for you. It may help to enable device hotplugging - support. As of this writing the exact hardware interface is - strongly in flux, so no good recommendation can be made. - -source "drivers/cpufreq/Kconfig" - -config CPU_FREQ_PMAC64 - bool "Support for some Apple G5s" - depends on CPU_FREQ && PMAC_SMU && PPC64 - select CPU_FREQ_TABLE - help - This adds support for frequency switching on Apple iMac G5, - and some of the more recent desktop G5 machines as well. - -config IBMVIO - depends on PPC_PSERIES || PPC_ISERIES - bool - default y - -config U3_DART - bool - depends on PPC_MULTIPLATFORM - default n - -config MPIC_BROKEN_U3 - bool - depends on PPC_MAPLE - default y - -config GENERIC_TBSYNC - def_bool n - -config PPC_PMAC64 - bool - depends on PPC_PMAC - default y - -config BOOTX_TEXT - bool "Support for early boot text console" - depends PPC_OF - help - Say Y here to see progress messages from the boot firmware in text - mode.

If you have - a system with only one CPU, say N. If you have a system with more - than one CPU, say Y. - - If you say N here, the kernel will run on single and multiprocessor - machines, but will use only one CPU of a multiprocessor machine.

By using pipes or other transports made available to - the process as file descriptors supporting the read/write - syscalls, it's possible to isolate those applications in - their own address space using seccomp.
