Would like to store the CPU context of prev and next tasks in the function __switch_to()

[prasad sodagudi]

Hi,

Would like to store the previous and next tasks CPU contexts in a specific
location for snooping the task context information.

This would help me to debug  from RAM contents when cpu hang cases.



ENTRY(__switch_to)
 UNWIND(.fnstart        )
 UNWIND(.cantunwind     )
        add     ip, r1, #TI_CPU_SAVE
        ldr     r3, [r2, #TI_TP_VALUE]
 ARM(   stmia   ip!, {r4 - sl, fp, sp, lr} )    @ Store most regs on stack
< code >

Could you please share any code reference for this ?

-Thanks, Prasad
