Subject: [Qemu-devel] [PATCH qemu v5 0/2] vfio-pci: Allow mmap of MSIX BAR
Date: Tue, 30 Jan 2018 14:55:25 +1100 [thread overview]
Message-ID: <20180130035527.47336-1-aik@ozlabs.ru> (raw)
This is to enable MSIX BAR mapping to the guest and by the same time
avoid failing on p2p DMA mappings. This attempt makes a try to
separate p2p handling from msix.
This is based on sha1
a6506a9 Suraj Jitindar Singh "target/ppc/spapr: Add H-Call H_GET_CPU_CHARACTERISTICS".
Please comment. Thanks.
