virtio: Add a Sandbox transport driver

2018-11-14T17:16:28Z

This driver provides support for Sandbox implementation of virtio transport driver which is used for testing purpose only. Two drivers are provided. The 2nd one is a driver that lacks the 'notify' op. Signed-off-by: Bin Meng Reviewed-by: Simon Glass

virtio: net: Support non-legacy device

2018-11-14T17:16:28Z

For v1.0 compliant device, it always assumes the member 'num_buffers' exists in the struct virtio_net_hdr while the legacy driver only presented 'num_buffers' when VIRTIO_NET_F_MRG_RXBUF was negotiated. Without that feature the structure was 2 bytes shorter. Update the driver to support the non-legacy device. Signed-off-by: Bin Meng Reviewed-by: Simon Glass

virtio: pci: Support non-legacy PCI transport device

2018-11-14T17:16:28Z

By default QEMU creates legacy PCI transport devices, but we can ask QEMU to create non-legacy one if we pass additional device property/value pairs in the command line: -device virtio-blk-pci,disable-legacy=true,disable-modern=false This adds a new driver driver to support non-legacy (modern) device mode. Previous driver/file name is changed accordingly. Signed-off-by: Bin Meng Reviewed-by: Simon Glass

virtio: Add virtio over pci transport driver

2018-11-14T17:16:28Z

This adds a transport driver that implements UCLASS_VIRTIO for virtio over pci, which is commonly used on x86. It only supports the legacy interface of the pci transport, which is the default device that QEMU emulates. Signed-off-by: Bin Meng Reviewed-by: Simon Glass

virtio: Add virtio over mmio transport driver

2018-11-14T17:16:27Z

VirtIO can use various different buses and virtio devices are commonly implemented as PCI devices. But virtual environments without PCI support (a common situation in embedded devices models) might use simple memory mapped device (“virtio-mmio”) instead of the PCI device. This adds a transport driver that implements UCLASS_VIRTIO for virtio over mmio. Signed-off-by: Tuomas Tynkkynen Signed-off-by: Bin Meng Reviewed-by: Simon Glass

virtio: Add codes for virtual queue/ring management

2018-11-14T17:16:27Z

This adds support for managing virtual queue/ring, the channel for high performance I/O between host and guest. Signed-off-by: Tuomas Tynkkynen Signed-off-by: Bin Meng Reviewed-by: Simon Glass

dm: Add a new uclass driver for VirtIO transport devices

2018-11-14T17:16:27Z

This adds a new virtio uclass driver for “virtio” [1] family of devices that are are found in virtual environments like QEMU, yet by design they look like physical devices to the guest. The uclass driver provides child_pre_probe() and child_post_probe() methods to do some common operations for virtio device drivers like device and driver supported feature negotiation, etc. [1] http://docs.oasis-open.org/virtio/virtio/v1.0/virtio-v1.0.pdf Signed-off-by: Tuomas Tynkkynen Signed-off-by: Bin Meng Reviewed-by: Simon Glass
