Add -git to version so it doesn't look like a release. This is just so when people built stuff from git it can be identified as such from the version string. Signed-off-by: Simon Horman <horms@verge.net.au>

2008-02-19Add ARM support to kexecRichard Purdie
Add ARM support to kexec including commandline support through ATAGs. The kernel syscall support has already been merged and kernel ATAG exporting is queued for 2.6.25 (its optional for kexec). Based on work by various people, notably Uli Luckas <u.luckas@road.de> for adding ATAG support. Signed-off-by: Richard Purdie <rpurdie@rpsys.net> Signed-off-by: Simon Horman <horms@verge.net.au>
2008-02-19sh: Remove hardcoded PAGE_SIZE in NetBSD loaderPaul Mundt
The Linux host supports a multitude of page sizes, so having this hardcoded doesn't really help matters. This also has the benefit of killing off dependence on asm/ headers when none is needed. While I'm not suggesting that anyone actually boot NetBSD, without this, my build also ends up breaking.

2008-02-19Use zlib if presentSimon Horman
Hi, This fixes a minor regression that occured with Jeremy's recent reworking of the build system. I guess he wasn't dealing with compressed images and thus didn't notice that zlib support had been disabled. The fix involves updating an #ifdef to use the new symbol, and ensuring that -lz is passed to the linker as neccessary.

2008-01-18Log unknown reloc name instead of its numberKevin Tegtmeier
I included a one-line patch to kexec-tools-testing, at Bernhard Walle's request. This prints the relocation type as a string. I noticed that other architectures do not use reloc_name, but instead just print the r_type. I find the reloc_name useful.

2007-12-19Don't assume we can re-make MakefileJeremy Kerr
We currently assume that we can recreate the Makefile by running ./configure, but we don't have the args available, so it's likely that the Makefile will be generated incorrectly. This change depends on config.status instead. We won't get the configure re-run if configure.ac is updated, but we still have the Makefile.in dependency.

2007-12-19Build system simplification/standardisationJeremy Kerr
This change makes kexec-tools work more like a standard configure-make- make-install-type project: * Remove $(OBJDIR) stuff. To do an out-of-tree build, just configure from a different directory. * Use the implicit Makefile rules more, and just edit the compiler flags for specific targets. * Simplify compiler/linker flags - no need for EXTRA_* * Add TARGET_CC, and improve checks for BUILD_CC too. * Set arch-specific flags in arch-specific makefiles, not conditional on $(ARCH). * Generate dependency files in the main compile, rather than as a separate step. * Don't #include sha256.c, but re-build it into the purgatory. Still a work-in-progress. Signed-off-by: Jeremy Kerr <jk@ozlabs.org> Signed-off-by: Simon Horman <horms@verge.net.au>

2007-12-19Use --target for target architecture specificationJeremy Kerr
Instead of using a combination of ARCH and --host, use --target. It's possible to have host != target. For example, building a ppc kexec binary for a ppc64 kernel. In this case, the kexec binary is compiled for 32-bit, while the purgatory object is 64-bit. Signed-off-by: Jeremy Kerr <jk@ozlabs.org> Signed-off-by: Simon Horman <horms@verge.net.au>

2007-11-14Fix the feature determining ELF32/ELF64 automaticallyKen'ichi Ohmichi
Hi, This patch fixes the problem that the kexec command cannot determine ELF32/ELF64 automatically. On i386 system, the kexec command always determined an ELF32 /proc/vmcore even if the memory is 4GB or larger, because of referring the outside of the array "range[]".

There is a compatibility problem that the kexec command fails on kernels which don't have /sys/kernel/vmcoreinfo: # ls /sys/kernel/ debug kexec_crash_loaded kexec_loaded security uevent_helper uevent_seqnum # (There is not /sys/kernel/vmcoreinfo.) # # kexec -p --args-linux vmlinuz --initrd=initrd.img Could not open "/sys/kernel/vmcoreinfo": No such file or directory # To fix the problem, could you please apply the attached patch ?

2007-10-18Pass vmcoreinfo's address and sizeKen'ichi Ohmichi
The patch is for kexec-tools-testing-20070330. (http://www.kernel.org/pub/linux/kernel/people/horms/kexec-tools/) The kexec command gets the address and size of the vmcoreinfo data from /sys/kernel/vmcoreinfo, and passes them to the second kernel through ELF header of /proc/vmcore. When the second kernel is booting, the kernel gets them from the ELF header and creates vmcoreinfo's PT_NOTE segment into /proc/vmcore.

Use /proc/iomem_machine for ia64 xen where pysical and machine efi maps differ. Without this kexec gets a very jaded view of the world, and /proc/vmcore after a kdump will only have a partial memory dump. Requires a companion patch to kexec-tools.

2007-10-17Allow architectures to specify the location of /proc/iomemSimon Horman
On ia64 XEN it is sometimes neccessary to use an alternate location for the information that is usually provided by /proc/iomem. By having the path returned by a function, which can be overriden on a per-architecture basis, it is possible for ia64 XEN to make use of existing generic code. Hopefully other achitectures can use this infastructure as the need arises. If the machine parameter is zero, then iomem file relating to the currently running kernel should be returned. If the machine parameter is non-zero then iomem file, relating to the underlying hypervisor, should be returned. In the simple case, these will be the same file.

2007-07-27Determine ELF32/ELF64 automatically on i386Bernhard Walle
On i386, kexec generates ELF64 core headers by default if the user doesn't override this via a command line option. Because GDB cannot analyse ELF64 core dumps on 32 bit platforms, it's a bad idea to use ELF64 if it's not needed. This patch selects ELF32 if the biggest memory address fits in 32 bit address space, which should be the case on non PAE systems. If the user specifies a command line option, that option overrides the detection. Signed-off-by: Bernhard Walle <bwalle@suse.de> Signed-off-by: Simon Horman <horms@verge.net.au>
2007-06-19kexec ppc64: fix misaligned cmdlineMichael Neuling
If the cmdline changes between boots, we can get misalignment of the bootargs entry, which in turn corrupts our device tree blob and hence kills our kexec boot. Also, if there was no /chosen/bootargs previously, we'd never add a new one. This ignores the bootargs while parsing the tree and inserts it later.
