Subject: [PATCH] Add quirk for SLES9 LKCD header
|
||
|
|
Upstream: never
|
||
|
|
|
||
|
|
On SLES9, we have a different header on IA64:
|
||
|
|
|
||
|
|
SLES 10:
|
||
|
|
|
||
|
|
typedef struct __dump_header_asm {
|
||
|
|
uint64_t dha_magic_number;
|
||
|
|
uint32_t dha_version;
|
||
|
|
uint32_t dha_header_size;
|
||
|
|
uint64_t dha_pt_regs;
|
||
|
|
struct pt_regs dha_regs;
|
||
|
|
uint64_t dha_rnat;
|
||
|
|
uint64_t dha_pfs;
|
||
|
|
uint64_t dha_bspstore;
|
||
|
|
uint32_t dha_smp_num_cpus;
|
||
|
|
uint32_t dha_dumping_cpu;
|
||
|
|
struct pt_regs dha_smp_regs[NR_CPUS];
|
||
|
|
uint64_t dha_smp_current_task[NR_CPUS];
|
||
|
|
uint64_t dha_stack[NR_CPUS];
|
||
|
|
uint64_t dha_stack_ptr[NR_CPUS];
|
||
|
|
uint64_t dha_kernel_addr;
|
||
|
|
} __attribute__((packed)) dump_header_asm_t;
|
||
|
|
|
||
|
|
SLES 9:
|
||
|
|
typedef struct __dump_header_asm {
|
||
|
|
uint64_t dha_magic_number;
|
||
|
|
uint32_t dha_version;
|
||
|
|
uint32_t dha_header_size;
|
||
|
|
uint64_t dha_kernel_addr;
|
||
|
|
uint64_t dha_pt_regs;
|
||
|
|
struct pt_regs dha_regs;
|
||
|
|
uint64_t dha_rnat;
|
||
|
|
uint64_t dha_pfs;
|
||
|
|
uint64_t dha_bspstore;
|
||
|
|
uint32_t dha_smp_num_cpus;
|
||
|
|
uint32_t dha_dumping_cpu;
|
||
|
|
struct pt_regs dha_smp_regs[NR_CPUS];
|
||
|
|
uint64_t dha_smp_current_task[NR_CPUS];
|
||
|
|
uint64_t dha_stack[NR_CPUS];
|
||
|
|
uint64_t dha_stack_ptr[NR_CPUS];
|
||
|
|
} __attribute__((packed)) dump_header_asm_t;
|
||
|
|
|
||
|
|
That patch tries to guess if it's a SLES 9 or a SLES 10 header
|
||
|
|
at runtime.
