I have a custom design with 1GB of RAM on i.MX8MM however the dtsi file is setting the shared-dma-pool with a quiet huge size.
/* global autoconfigured region for contiguous allocations */
compatible = "shared-dma-pool";
size = <0 0x28000000>;
alloc-ranges = <0 0x40000000 0 0x60000000>;
I don't have video processing, how could I decrease it to its minimal value in a good way and with which values ?
