If you have a system with only one CPU, like most personal computers, 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. If you say Y here, the kernel will run on many, but not all, singleprocessor machines. On a singleprocessor machine, the kernel will run faster if you say N here. People using multiprocessor machines who say Y here should also say Y to "Enhanced Real Time Clock Support", below. See also the SMP-HOWTO available at .

The maximum supported value is 32 for 32-bit kernel and 64 for 64-bit kernels; the minimum value which makes sense is 1 for Qemu (useful only for kernel debugging purposes) and 2 for all others. This is purely to save memory - each supported CPU adds approximately eight kilobytes to the kernel image.

It is like a reboot but it is independent of the system firmware. And like a reboot you can start any kernel with it, not just Linux. The name comes from the similarity 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. config CRASH_DUMP bool "Kernel crash dumps" help Generate crash dump after being started by kexec. This should be normally only set in special crash dump kernels which are loaded in the main kernel with kexec-tools into a specially reserved region and then later executed after a crash by kdump/kexec. The crash dump kernel must be compiled to a memory address not used by the main kernel or firmware using PHYSICAL_START. config PHYSICAL_START hex "Physical address where the kernel is loaded" default "0xffffffff84000000" if 64BIT default "0x84000000" if 32BIT depends on CRASH_DUMP help This gives the CKSEG0 or KSEG0 address where the kernel is loaded. If you plan to use kernel for capturing the crash dump change this value to start of the reserved region (the "X" value as specified in the "crashkernel=YM@XM" command line boot parameter passed to the panic-ed kernel). config SECCOMP bool "Enable seccomp to safely compute untrusted bytecode" depends on PROC_FS default y help This kernel feature is useful for number crunching applications that may need to compute untrusted bytecode during their execution. 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. Once seccomp is enabled via /proc//seccomp, it cannot be disabled and the task is only allowed to execute a few safe syscalls defined by each seccomp mode. If unsure, say Y.
