generate incorrect output with certain kernel constructs when
-mregparm=3 is used.
-config KERN_PHYS_OFFSET
- int "Physical address where the kernel is loaded (1-112)MB"
- range 1 112
- default "1"
- help
- This gives the physical address where the kernel is loaded.
- Primarily used in the case of kexec on panic where the
- recovery kernel needs to run at a different address than
- the panic-ed kernel.
-
-config KEXEC
- bool "kexec system call (EXPERIMENTAL)"
- depends on EXPERIMENTAL
- help
- kexec is a system call that implements the ability to shutdown your
- current kernel, and to start another kernel. 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.
-
-config CRASH_DUMP
- bool "kernel crash dumps (EXPERIMENTAL)"
- depends on KEXEC
- help
- Generate crash dump using kexec.
-
-config BACKUP_BASE
- int "location from where the crash dumping kernel will boot (MB)"
- depends on CRASH_DUMP
- default 16
- help
- This is the location where the second kernel will boot from.
-
-config BACKUP_SIZE
- int "Size of memory used by the crash dumping kernel (MB)"
- depends on CRASH_DUMP
- range 16 64
- default 32
- help
- The size of the second kernel's memory.
