Subject: [PATCH v4 08/13] mips/kexec: refactor for kernel/Kconfig.kexec
Date: Wed, 5 Jul 2023 10:19:59 -0400 [thread overview]
Message-ID: <20230705142004.3605799-9-eric.devolder@oracle.com> (raw)
In-Reply-To: <20230705142004.3605799-1-eric.devolder@oracle.com>
The kexec and crash kernel options are provided in the common
kernel/Kconfig.kexec. Utilize the common options and provide
the ARCH_SUPPORTS_ and ARCH_SELECTS_ entries to recreate the
equivalent set of KEXEC and CRASH options.

- bool "Kexec system call"
- select KEXEC_CORE
- 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 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. 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.
