2021-09-05virtio/vsock: rename 'EOR' to 'EOM' bit.Arseny Krasnov3-14/+14
This current implemented bit is used to mark end of messages ('EOM' - end of message), not records('EOR' - end of record). Also rename 'record' to 'message' in implementation as it is different things.

2021-09-05virtio: Bind virtio device to device-tree nodeViresh Kumar1-3/+54
Bind the virtio devices with their of_node. This will help users of the virtio devices to mention their dependencies on the device in the DT itself. Like GPIO pin users can use the phandle of the device node, or the node may contain more subnodes to add i2c or spi eeproms and other users.

2021-09-05vdpa_sim: Use iova_shift() for the size passed to alloc_iova()Xie Yongji1-1/+2
The size passed to alloc_iova() should be the size of page frames. Now we use byte granularity for the iova domain, so it's safe to pass the size in bytes to alloc_iova(). But it would be better to use iova_shift() for the size to avoid future bugs if we change granularity.

2021-09-05vdpa/mlx5: Add multiqueue supportEli Cohen3-31/+169
Multiqueue support requires additional virtio_net_q objects to be added or removed per the configured number of queue pairs. In addition the RQ tables needs to be modified to match the number of configured receive queues so the packets are dispatched to the right virtqueue according to the hash result. Note: qemu v6.0.0 is broken when the device requests more than two data queues; no net device will be created for the vdpa device. To avoid this, one should specify mq=off to qemu. In this case it will end up with a single queue. Signed-off-by: Eli Cohen <[email protected]> Link: https://lore.kernel.org/r/[email protected] Signed-off-by: Michael S. Tsirkin <[email protected]>
2021-09-05vdpa/mlx5: Add support for control VQ and MAC settingEli Cohen5-32/+329
Add support to handle control virtqueue configurations per virtio specification. The control virtqueue is implemented in software and no hardware offloading is involved. Control VQ configuration need task context, therefore all configurations are handled in a workqueue created for the purpose. Modifications are made to the memory registration code to allow for saving a copy of itolb to be used by the control VQ to access the vring. The max number of data virtqueus supported by the driver has been updated to 2 since multiqueue is not supported at this stage and we need to ensure consistency of VQ indices mapping to either data or control VQ.

Instead, define an array of struct vdpa_callback on struct mlx5_vdpa_net and use it to store callbacks for any virtqueue provided. This is required due to the fact that callback configurations arrive before feature negotiation.

The problem is that request is freed regardless of usb_ep_dequeue(), which ends up badly if the request is not actually dequeued yet.

2021-08-27PCI/MSI: Skip masking MSI-X on Xen PVMarek Marczykowski-Górecki1-0/+3
When running as Xen PV guest, masking MSI-X is a responsibility of the hypervisor. The guest has no write access to the relevant BAR at all - when it tries to, it results in a crash like this: BUG: unable to handle page fault for address: ffffc9004069100c #PF: supervisor write access in kernel mode #PF: error_code(0x0003) - permissions violation RIP: e030:__pci_enable_msix_range.part.0+0x26b/0x5f0 e1000e_set_interrupt_capability+0xbf/0xd0 [e1000e] e1000_probe+0x41f/0xdb0 [e1000e] local_pci_probe+0x42/0x80 (...) The recently introduced function msix_mask_all() does not check the global variable pci_msi_ignore_mask which is set by XEN PV to bypass the masking of MSI[-X] interrupts. Add the check to make this function XEN PV compatible.
