similar to: [PATCH v3 0/6] virtio 1.0 enhancements

transports need to be able to detect legacy-only devices (ATM balloon only) to use legacy path to drive them. Add a core API to do just that. The implementation just blacklists balloon: not too pretty, but let's not over-engineer. Signed-off-by: Michael S.

This patchset tries to go towards implementing both virtio-1 compliant and transitional virtio drivers in Linux. Branch available at git://git.kernel.org/pub/scm/linux/kernel/git/kvms390/linux virtio-1 This is based on some old patches by Rusty to handle extended feature bits and endianness conversions. Thomas implemented the new virtio-ccw transport revision command, and I hacked up some

Aiming these for coming merge window. Nothing should change, but get ready for a non-guest-endian config transports, and > 32 features bits. Final one is just an overdue consolidation. Cheers, Rusty. Rusty Russell (7): virtio_config: introduce size-based accessors. virtio: use size-based config accessors. virtio_config: helpers for non-converting accessors. virtio_config: make

At this point, no transports set any of the high 32 feature bits. Since transports generally can't (yet) cope with such bits, add BUG_ON checks to make sure they are not set by mistake.

Hi all: This series try to share MSIX irq for each tx/rx queue pair. This is done through: - introducing virtio pci channel which are group of virtqueues that sharing a single MSIX irq (Patch 1) - expose channel setting to virtio core api (Patch 2) - try to use channel setting in virtio-net (Patch 3) For the transport that does not support channel, channel paramters were simply ignored.
