[Crash-utility] [PATCH 0/4] crash utility: add ARM crashdump support

Hello Dave, First of all, thanks for the great tool! It is the best post-mortem analysis tool I've ever used. This series implements ARM support for the crash utility. Current implementation provides following: o Virtual to physical address translation through page tables o Stack unwinding support using ARM unwind tables o And some more to get minimal support for ARM architecture There are limitations, however: o Only one CPU is supported (I don't have access to ARM SMP hardware) o No support for stack unwinding with CONFIG_FRAMEPOINTER o Only diskdump format is supported (generated by makedumpfile) These apply on top of crash 5.0.5 sources. Please let me know, if there is something that needs to be changed. It would be great if you would consider taking these in upstream crash. With these patches, the crash utility can analyze ARM crashdumps pretty well (at least in my testing environment). What is missing, can be implemented later on when we have kernel[1] support and users. After this, all necessary userspace components should be ready for ARM architecture (kexec-tools, makedumpfile and crash utility). I've tested this on OMAP3 based platforms with 2.6.32 and latest mainline kernels (with the kdump patches). Regards, MW [1] Note that kernel crashdump support is not yet in mainline but I'm hoping that it will be merged eventually (patches are in RMK's patch tracker already).
