| |
We are using part of DRAM as shared memory between DSP and SoC. However, DSP can only access higher 1GB of DRAM.
In order to map the aforementioned memory I tried using ioremap and it blurted out the warning as mentioned in this article. https://lwn.net/Articles/409700/
What is the alternative to using ioremap to map specific RAM memory region for use in the driver as shared memory?
I tried memremap + reserved memory as well and it failed.
