Subject[RFC 0/2] SRAMFS a direct mapped SRAM pages into user space
Date
Hi all,

This patch set tries to introduce a direct mapping mechanism of SRAM
memory regions directly into user space.
This is a draft of some reaserch work which I am going to continue.
Since it is my last day in the office I have publish it as a RFC.

Benefits of having SRAM memory in the user space:
- lower latency access
- lower power usage
- managable scratchpad which could be sharable between processes
- could be used toughether with dedicated instructions like dot product
calculation

Regards,
Lukasz Luba
