Greetings, We are in the middle of developing a chassis which will be using Embedded Linux and during the course of configuration we've come across some questions that would need to be answered to ensure that we make the right system for current development and future deployment.
One of these things is the DMA pool that needs to be allocated for PCI devices DMA between system memory and device memory (if present). I've been trying to search but haven't found any document or anything that describes what a reasonable size of memory should be. As we are configuring a custom kernel, we'd like to know what the minimum is so that we don't run out of DMA pages, and what a reasonable maximum would be so that we don't waste memory. The chassis we are building will be a telecom chassis running various switch/routing applications. Any and all help and direction would be greatly appreciated.
