The following four patch series adds support to read vendor statistics for a vdpa device.
The first patch is just a cleanup fix. The second patch lays the ground to allow an upstream driver to provide statistics in the form of an attribute name/attribute value pairs.
The third patch makes changes to locking scheme to use readers/writers semaphore instead if mutex.
The fourth patch implements this for mlx5_vdpa which gives received descriptors and completed descriptors information for all the virtqueues.
The fifth patch changes reslock mutex to readers/writers semaphore to achieve the same goal as done in vdpa core.
Eli Cohen (5): vdpa: Fix error logic in vdpa_nl_cmd_dev_get_doit vdpa: Add support for querying vendor statistics net/vdpa: Use readers/writers semaphore instead of mutex vdpa/mlx5: Add support for reading descriptor statistics vdpa/mlx5: Use readers/writers semaphore instead of mutex
v6 -> v7: 1. Add a new mlx5 patch to modify reslock from a mutex to rw_semaphore 2. Clean old comments 3. Move VDPA_ATTR_DEV_NET_CFG_MAX_VQP attribute insertion from mlx5 to vdpa core.
