Mark, do you think it is possible for a QEMU command line option to actually load the saved OpenBIOS settings from a file and restore them into memory? I'm thinking something along the lines of -prom-memory <file name>.
From memory the reason this hasn't been done is because the NVRAM
interface is used across multiple architectures and there hasn't been a solution devised that would work well enough for all of them. Then again as the BIOSs involved have continued to develop, it may be now that some of the issues can now be solved so it never hurts to ask on the -devel list.
I'm wondering, why wouldn't it be enough to memmap a nvram file instead of mallocing (or whatever) the memory area?
