Hi,
Following set of patches go one step ahead in restoring the broken kdump functionality in -mm tree on x86. Most of the kdump functionality has now moved to kexec user space (kexec-tools).
This patch set performs following.
kexec-tool-1.101 (http://www.xmission.com/~ebiederm/files/kexec/kexec-tools-1.101.tar.gz) -----------------------------------------------------------------------
- Create a backup region and copy the first 640K of memory to backup region over a crash. - Generate Elf headers representing crashed memory and store in reserved region. Also appends the memmap= and elfcorehdr= parameters to command line internally to be passed to capture kernel.
2.6.11-rc4-mm1 -------------- - Export address of start of crash notes section (crash_notes) to user space through sysfs
I look forward for comments and suggestions. I have done basic testing on uni and 4way (SMT) systems.
2.6.11-rc4-mm1 does not boot if booted with kexec enabled and crashkernel=X@Y is passed as command line parameter. Following patch needs to be applied to rectify the problem.
