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 [1] http://ozlabs.org/pipermail/linuxppc-dev/2007-November/046739.html -- Anton Vorontsov email: [EMAIL PROTECTED] irc://irc.freenode.net/bd2 _______________________________________________ Linuxppc-dev mailing list Linuxppc-dev@ozlabs.org https://ozlabs.org/mailman/listinfo/linuxppc-dev
