[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index] [Xen-devel] new hypercall implementation question
Is it safe to pass three guest virtual addresses via a hypercall to Xen and expect Xen to safely copy data (two scalars and one array of pagesize-bytes... not necessarily aligned on a page boundary) back to the guest, or do I need to do something fancy to avoid weird corner cases, e.g. to ensure restartabililty in case of guest page fault? This is a privileged-only hypercall used only as part of save/restore/live-migrate (for tmem) if that is relevant.
