Currently it is only possible to set mem_access restrictions only for a contiguous range of GFNs (or, as a particular case, for a single GFN). This patch introduces a new libxc function taking an array of GFNs. The alternative would be to set each page in turn, using a userspace-HV roundtrip for each call, and triggering a TLB flush per page set.Signed-off-by: Razvan Cojocaru <rcojoc...@bitdefender.com> Acked-by: Wei Liu <wei.l...@citrix.com> --- Changes since V3: - Fixed ARM compilation (replaced ENOTSUP with EOPNOTSUPP, which is #defined in the in-tree errno.h). The multi code remains unimplemented for ARM (it depends on " [RFC 21/22] xen/arm: p2m: Re-implement p2m_set_mem_access using p2m_{set, get}_entry", and Julien Grall has gracefully accepted to defer implementation until after both patches go in).
