Hey! Please see the two RFC patches to add in the XENMEM_exchange hypercall another argument to get MFNs which are size aligned.
The use case is also attached - which is to provide the framework for dma_alloc_coherent which sets certain guarantees that were not provided by Linux Xen-SWIOTLB leading to driver corruptions. Thanks! _______________________________________________ Xen-devel mailing list Xen-devel@lists.xen.org https://lists.xen.org/xen-devel
