Hello, I am learning to program Radeon HD 7350 by reading the radeon driver source in Linux, and the guides/manuals from AMD.
I understand the general flow of initialization the driver performs. I have also been able to understand and re-implement the ATOM BIOS virtual machine. I am trying to program the device up from scratch (i.e. bare-metal). Do I need to perform all those steps that the driver does? Reading the evergreen_gpu_init function is demotivating; it initializes many fields and registers which I suspect may not be required for a minimal setup. Is posting the BIOS and loading the microcode enough to get me started with running basic tasks (DMA transfers, simple packet processing, etc.)? Thanks, Amol
