Hi all,
I want to get the task_struct entry of running process under arm
platform in gem5. How can I get the entry?
In kernel mode, I can get the thread_info struct by operating the
kernel stack pointer stored in the r13 (SP) register. And the task_struct is
stored in the thread_info struct. The code is :
addr = context->readIntReg(INTREG_SP) & (~0x1fff);
task_addr = vp.readGtoH<int32_t>(addr + 0xc); //task_struct
If using the same method in user mode, how can I get the content of
kernel r13 register?
Or are there other methods in order to get the task_struct entry of
current running process? For example, in x86 platform, there is a kernel
symbol indicating to the task_struct entry directly.
Thanks!
Best regards,
Yongbing Huang
