[Xen-devel] Re: Mini-OS in dom0 - virtual memory problems

Mini-OS assumes that the start of the text section is also the beginning of virtual address space[1]. However, it is generally bad idea not to start virtual address space at 4Mb boundary. The easiest way to fix your problem is to move text to 0xc0000000 or 0xc0400000. More extensive fix, which decouples VIRT_START from &_text is also possible, but I don't see a reason why it would be needed. Instead I've included a runtime check. Keir could you apply the patch?

I changed the beginning of text to 0xC0000000 and the page table setup seems to work, as does the rest of Mini-OS (except XenBus of course). Thank you very much!
