kdump saves the first 640kB physical memory in some backup region. The question of mine is how to find the backup region from vmcore.
First let me explain why I have such question. Fujitsu has sadump, Stand Alone Dump, which runs independently of kernel logic, and the generated vmcore contains a whole part of physical memory. The issue happens when sadump is triggered after kdump has run and passed the processing of saving the 640 kB memory in some backup region. The 640 kB memory contains the data used for paging, and if it's unavailable, we cannot access the region not straight mapped, for example, the regions allocated using valloc() such as kernel module data. According to a part of kexec-tools/kexec/crashdump-elf.c below, PT_LOAD entry in ELF segment corresponding to the 640kB backup region has offset to the backup region in p_offset. /* Setup PT_LOAD type program header for every system RAM chunk. * A seprate program header for Backup Region*/ for (i = 0; i < ranges; i++, range++) { unsigned long long mstart, mend; if (range->type != RANGE_RAM) continue; mstart = range->start; mend = range->end; if (!mstart && !mend) continue; phdr = (PHDR *) bufp; bufp += sizeof(PHDR); phdr->p_type = PT_LOAD; phdr->p_flags = PF_R|PF_W|PF_X; phdr->p_offset = mstart; if (mstart == info->backup_src_start && (mend - mstart + 1) == info->backup_src_size) phdr->p_offset = info->backup_start; /* We already prepared the header for kernel text. Map * rest of the memory segments to kernel linearly mapped * memory region. */ phdr->p_paddr = mstart; I've confirmed this on most of RHEL versions. But strangely, on RHEL6, kernel 2.6.32-71.34.1.el6.i686, I cannot find the PT_LOAD corresponding to the backup region. Here are sample ouput of crash utility. Complete ones are attached to this mail and contains all commands to search vmcore for the PT_LOAD corresponding to backup region. * 2.6.18-238.el5PAE RHEL5.6 struct elf64_phdr { p_type = 0x1, p_flags = 0x7, p_offset = 0x20f60000, p_vaddr = 0xc0000000, p_paddr = 0x0, p_filesz = 0xa0000, p_memsz = 0xa0000, p_align = 0x0 } * 2.6.32-71.34.1.el6.i686 RHEL6.0 struct elf64_phdr { p_type = 0x1, p_flags = 0x7, p_offset = 0x1000, p_vaddr = 0xc0001000, p_paddr = 0x1000, p_filesz = 0x98c00, p_memsz = 0x98c00, p_align = 0x0 } The above RHEL 5.6 kernel is just as I expect, but the below RHEL6.0 is different in that p_offset has the same value as p_paddr, and it is not the address of 640kB backup region. I don't know what's happening on RHEL6.0. Could anyone tell me this? Thanks. HATAYAMA, Daisuke
