vdpa/mlx5: Fix MQ to support non power of two num queues

2022-09-27T22:32:45Z

RQT objects require that a power of two value be configured for both rqt_max_size and rqt_actual size. For create_rqt, make sure to round up to the power of two the value of given by the user who created the vdpa device and given by ndev->rqt_size. The actual size is also rounded up to the power of two using the current number of VQs given by ndev->cur_num_vqs. Same goes with modify_rqt where we need to make sure act size is power of two based on the new number of QPs. Without this patch, attempt to create a device with non power of two QPs would result in error from firmware.

vdpa/mlx5: Fix possible uninitialized return value

2022-08-11T14:00:36Z

Initialize err local variable to return -EAGAIN if the asid cannot be found thus avoiding returning uninitialized value.

vdpa/mlx5: Support different address spaces for control and data

2022-08-11T08:26:08Z

Partition virtqueues to two different address spaces: one for control virtqueue which is implemented in software, and one for data virtqueues.

vdpa/mlx5: Implement susupend virtqueue callback

2022-08-11T08:26:08Z

Implement the suspend callback allowing to suspend the virtqueues so they stop processing descriptors. This is required to allow to query a consistent state of the virtqueue while live migration is taking place.

vdpa/mlx5: Initialize CVQ vringh only once

2022-06-24T06:49:47Z

Currently, CVQ vringh is initialized inside setup_virtqueues() which is called every time a memory update is done. This is undesirable since it resets all the context of the vring, including the available and used indices. Move the initialization to mlx5_vdpa_set_status() when VIRTIO_CONFIG_S_DRIVER_OK is set.

vdpa/mlx5: Update Control VQ callback information

2022-06-24T06:49:47Z

The control VQ specific information is stored in the dedicated struct mlx5_control_vq. When the callback is updated through mlx5_vdpa_set_vq_cb(), make sure to update the control VQ struct.
