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. For devices that does not use channel, it can simply pass NULL or zero to virito core. With the patch, 1 MSIX irq were saved for each TX/RX queue pair. Please review. Thanks Jason Wang (3): virtio-pci: introduce channels virtio: let vp_find_vqs accept channel setting paramters virtio-net: using single MSIX irq for each TX/RX queue pair drivers/block/virtio_blk.c | 3 +- drivers/char/virtio_console.c | 3 +- drivers/lguest/lguest_device.c | 5 +- drivers/misc/mic/card/mic_virtio.c | 5 +- drivers/net/caif/caif_virtio.c | 3 +- drivers/net/virtio_net.c | 26 ++++- drivers/remoteproc/remoteproc_virtio.c | 5 +- drivers/rpmsg/virtio_rpmsg_bus.c | 3 +- drivers/s390/kvm/kvm_virtio.c | 5 +- drivers/s390/kvm/virtio_ccw.c | 5 +- drivers/scsi/virtio_scsi.c | 3 +- drivers/virtio/virtio_balloon.c | 3 +- drivers/virtio/virtio_mmio.c | 5 +- drivers/virtio/virtio_pci_common.c | 207 ++++++++++++++++++++------------- drivers/virtio/virtio_pci_common.h | 19 ++- include/linux/virtio_config.h | 8 +- 16 files changed, 208 insertions(+), 100 deletions(-) -- 1.8.3.1 -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majord...@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
