acessin the kernel register inside panic function

[balajinr]

Hi,

I want to dump the kernel register values in the SRAM during , when the kernel panic occurs .

I want to read the values of this structure (ie) pt_regs_data and dump its value in the SRAM inside the panic fuction of the kernel .

I tried to use the in the linux/kernel/panic.c file .


thread_info = current_thread_info();

pt_regs_data = (struct pt_regs*)((unsigned long)thread_info+THREAD_SIZE);

memcpy((char *)SRAM,(char*)pt_regs_data,sizeof(struct pt_regs));

if I am not wrong this shall give the register values of the panic thread not the register values of the thread that caused the panic .



Thanks

Doesn't this information get saved in the kernel crash dump file?
