8b6c724c - virtio: vdpa: vDPA driver for Marvell OCTEON DPU devices

Fri, 14 Jun 2024 14:46:59 +0000

virtio: vdpa: vDPA driver for Marvell OCTEON DPU devicesThis commit introduces a new vDPA driver specifically designed formanaging the virtio control plane over the vDPA bus for OCTEON DPUdevices. The driver consists of two layers:1. Octep HW Layer (Octeon Endpoint): Responsible for handling hardwareoperations and configurations related to the DPU device.2. Octep Main Layer: Compliant with the vDPA bus framework, this layerimplements device operations for the vDPA bus. It handles deviceprobing, bus attachment, vring operations, and other relevant tasks.Signed-off-by: Srujana Challa Signed-off-by: Vamsi Attunuru Signed-off-by: Shijith Thotton Signed-off-by: Nithin Dabilpuram Acked-by: Jason Wang Message-Id: <20240614144659.1776067-1-schalla@marvell.com>Signed-off-by: Michael S.

a16291b5 - pds_vdpa: Add new vDPA driver for AMD/Pensando DSC

Fri, 19 May 2023 21:56:24 +0000

pds_vdpa: Add new vDPA driver for AMD/Pensando DSCThis is the initial auxiliary driver framework for a new vDPAdevice driver, an auxiliary_bus client of the pds_core driver.The pds_core driver supplies the PCI services for the VF deviceand for accessing the adminq in the PF device.This patch adds the very basics of registering for the auxiliarydevice and setting up debugfs entries.Signed-off-by: Shannon Nelson Acked-by: Jason Wang Message-Id: <20230519215632.12343-4-shannon.nelson@amd.com>Signed-off-by: Michael S.

c8a6153b - vduse: Introduce VDUSE - vDPA Device in Userspace

Tue, 31 Aug 2021 10:36:33 +0000

vduse: Introduce VDUSE - vDPA Device in UserspaceThis VDUSE driver enables implementing software-emulated vDPAdevices in userspace. The vDPA device is created byioctl(VDUSE_CREATE_DEV) on /dev/vduse/control. Then a char deviceinterface (/dev/vduse/$NAME) is exported to userspace for deviceemulation.In order to make the device emulation more secure, the device'scontrol path is handled in kernel. A message mechnism is introducedto forward some dataplane related control messages to userspace.And in the data path, the DMA buffer will be mapped into userspaceaddress space through different ways depending on the vDPA bus towhich the vDPA device is attached. In virtio-vdpa case, the MMU-basedsoftware IOTLB is used to achieve that. And in vhost-vdpa case, theDMA buffer is reside in a userspace memory region which can be sharedto the VDUSE userspace processs via transferring the shmfd.For more details on VDUSE design and usage, please see the follow-onDocumentation commit.NB(mst): when merging this withb542e383d8c0 ("eventfd: Make signal recursion protection a task bit")replace eventfd_signal_count with eventfd_signal_allowed,and drop the previous("eventfd: Export eventfd_wake_count to modules").Signed-off-by: Xie Yongji Acked-by: Jason Wang Link: https://lore.kernel.org/r/20210831103634.33-13-xieyongji@bytedance.comSigned-off-by: Michael S.

vdpa: introduce virtio pci driverThis patch introduce a vDPA driver for virtio-pci device. It bridgesthe virtio-pci control command to the vDPA bus. This will be used forfeatures prototyping and testing.Note that get/restore virtqueue state is not supported which needsextension on the virtio specification.Signed-off-by: Jason Wang Link: https://lore.kernel.org/r/20210223061905.422659-4-jasowang@redhat.comSigned-off-by: Michael S.

c9b9f5f8 - vdpa: move to drivers/vdpa

Tue, 31 Mar 2020 19:15:14 +0000

vdpa: move to drivers/vdpaWe have both vhost and virtio drivers that depend on vdpa.It's easier to locate it at a top level directory otherwisewe run into issues e.g. if vhost is built-in but virtiois modular. Let's just move it up a level.Reported-by: Randy Dunlap Signed-off-by: Michael S. Tsirkin List of files: /linux-6.15/drivers/vdpa/Makefile
