Part Number: AM5706
Tool/software: Linux
Hi everybody:
I learnt that the AM5706 has the spinlock feature implemented in the silicon.
So in principle, any operating system can make use of it. The think is that if you want to
use them, you first need to disable interrupts, then get the spinlock.
Once you got the spinlock, you have to run fast code and then release the spinlock and
leave the interrupts as they were at the beginning.
My question is:
I have Linux in the A15 and TI-RTOS in the DSP. I want to use the spinlock to protect
some access to share memory, but I want to make sure tha Linux is using the hardware
spinlock provided by the AM5706 and not a software spinlock.
How can I do this in both, user and kernel space?
Regards
Billa
