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. _______________________________________________ Kernelnewbies mailing list Kernelnewbies@xxxxxxxxxxxxxxxxx https://lists.kernelnewbies.org/mailman/listinfo/kernelnewbies
