Hi, This patch uses the kernel start address from the dump header on IA64 instead of the default value. This has been reported as bug on a SGI machine -- lcrash was able to open the dump because it uses the start address of the header, crash was not. Troy, ACK? Dave: That's my last LKCD patch for now. ;-) Signed-off-by: Bernhard Walle <bwalle(a)suse.de&gt; --- defs.h | 2 ++ ia64.c | 11 ++++++++++- lkcd_common.c | 21 +++++++++++++++++++++ lkcd_fix_mem.c | 10 ++++++++++ 4 files changed, 43 insertions(+), 1 deletion(-) --- a/defs.h +++ b/defs.h @@ -3874,6 +3874,7 @@ int fix_addr_v8(struct _dump_header_asm_ int lkcd_dump_init_v8_arch(struct _dump_header_s *dh); int fix_addr_v7(int); int get_lkcd_regs_for_cpu_arch(int cpu, ulong *eip, ulong *esp); +int lkcd_get_kernel_start_v8(ulong *addr); /* * lkcd_v8.c @@ -4144,6 +4145,7 @@ int lkcd_load_dump_page_header(void *, u void lkcd_dumpfile_complaint(uint32_t, uint32_t, int); int set_mb_benchmark(ulong); ulonglong fix_lkcd_address(ulonglong); +int lkcd_get_kernel_start(ulong *addr); int get_lkcd_regs_for_cpu(struct bt_info *bt, ulong *eip, ulong *esp); /* --- a/ia64.c +++ b/ia64.c @@ -3810,7 +3810,16 @@ ia64_calc_phys_start(void) phys_start); } return; - } + } else if (LKCD_DUMPFILE()) { + + if (lkcd_get_kernel_start(&phys_start)) { + machdep->machspec->phys_start = phys_start; + if (CRASHDEBUG(1)) + fprintf(fp, + "LKCD dump: phys_start: %lx\n", + phys_start); + } + } if ((vd = get_kdump_vmcore_data())) { /* --- a/lkcd_common.c +++ b/lkcd_common.c @@ -787,6 +787,27 @@ get_offset(uint64_t paddr) } +#ifdef IA64 + +int +lkcd_get_kernel_start(ulong *addr) +{ + if (!addr) + return 0; + + switch (lkcd->version) + { + case LKCD_DUMP_V8: + case LKCD_DUMP_V9: + return lkcd_get_kernel_start_v8(addr); + + default: + return 0; + } +} + +#endif + int lkcd_lseek(physaddr_t paddr) --- a/lkcd_fix_mem.c +++ b/lkcd_fix_mem.c @@ -97,4 +97,14 @@ get_lkcd_switch_stack(ulong task) return 0; } +int lkcd_get_kernel_start_v8(ulong *addr) +{ + if (!addr) + return 0; + + *addr = ((dump_header_asm_t *)lkcd->dump_header_asm)->dha_kernel_addr; + + return 1; +} + #endif // IA64
