[PATCH] vdpa/mlx5: Support interrupt bypassing

2023-06-07 Thread Dragos Tatulea via Virtualization
From: Eli Cohen Add support for generation of interrupts from the device directly to the VM to the VCPU thus avoiding the overhead on the host CPU. When supported, the driver will attempt to allocate vectors for each data virtqueue. If a vector for a virtqueue cannot be provided it will use the
