| |
Would there be any issues for optimization purpose I do a mmap to a peripheral register to directly access it from userspace ? This is considering the peripheral already has a Kernel driver through which you can set the register bit.
Basically I want to avoid the additional context switch on entering the Kernel to set that one bit in the Peripheral register.
I request you to please share your thoughts.
Best regards, Krishna
