Hi again, everyone; A question about kseg0: Do system designers usually set things up such that kseg0 begins at the start of physical memory, regardless of the xkphys offset at which RAM starts? Or is it necessary to add the offset at which RAM starts to the kseg0 base, making it possible that the system designers could start RAM addresses high enough (above 512M) to make kseg0 unusable? Does anyone have an implementation in which this is the case? If kseg0 provides a window beginning at physical address 0, that means I'm going to try using Ralf's mapped kernel option, or I'll have to get the kernel up and running in 64 bit only mode (I believe 32 bit compat binaries would still work, since kuseg can be mapped).
