If default variant is not filtered by only or no filters then only default variant is chosen. This behavior was used for optimizing of speed of Cartesian config. If variants don't have default variant then everything works as usual. Default variant must be in variants with with_default exactly one

[PATCHv2] KVM: Allow cross page reads and writes from cached translations.

2013-03-29 Thread Andrew Honig
This patch adds support for kvm_gfn_to_hva_cache_init functions for reads and writes that will cross a page. If the range falls within the same memslot, then this will be a fast operation. If the range is split between two memslots, then the slower kvm_read_guest and kvm_write_guest are used. Te

Best way to busy-wait for a virtio queue?

2013-03-29 Thread H. Peter Anvin
