Subject: [RFC][PATCH 0/8] kexec/kdump support for ppc32
Date: Fri, 1 Aug 2008 18:13:06 +0400 [thread overview]
Message-ID: <20080801141306.GA29127@polina.dev.rtsoft.ru> (raw)
Hi all,
I refreshed some Dale Farnsworth's kexec/kdump patches[1] against
the latest kernel, and here they are.
There is a difference though. Dale's patches were using
kmap_atomic_pfn() to map oldmem memory, while for this patches
I took PPC64 approach to use ioremap(). This is done to be able
to support kdump on !HIGHMEM kernels.
Also, please take a special look into 8/8 patch, there is a hunk
marked with "XXX:", which I don't quite understand for PPC64 case
(this hunk also persist in the original Dale's patch, and w/o it
the capturing kernel doesn't boot on ppc32).
I'll try to refresh BookE support as soon as I'll find some BookE
board.
The patchset includes:
- Kexec support
[PATCH 1/8] powerpc: set up OF properties for ppc32 kexec
[PATCH 2/8] powerpc: make default kexec/crash_kernel ops implicit
[PATCH 3/8] powerpc: remove default kexec/crash_kernel ops assignments
2/8 and 3/8 patches are used to avoid adding lots of default ops
to the board files.
- Kdump support
[PATCH 4/8] powerpc: add the ability for a classic ppc kernel to be loaded at 32M
[PATCH 5/8] powerpc: allow to ioremap RAM addresses for kdump kernel on ppc32
[PATCH 6/8] powerpc: set up OF properties for ppc32 kdump
[PATCH 7/8] powerpc: implement crash_setup_regs for ppc32
[PATCH 8/8] powerpc: last bits to support kdump on ppc32
