Subject: [PATCH v6 10/14] powerpc/kexec: refactor for kernel/Kconfig.kexec
Date: Wed, 12 Jul 2023 12:15:41 -0400 [thread overview]
Message-ID: <20230712161545.87870-11-eric.devolder@oracle.com> (raw)
In-Reply-To: <20230712161545.87870-1-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.

- 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.

- for kernel and initramfs as opposed to a list of segments as is the
