mlx5dv_get_vfio_device_list - Get list of available devices to be used over VFIO

attr Describe the VFIO devices to return in list. attr argument struct mlx5dv_vfio_context_attr { const char *pci_name; uint32_t flags; uint64_t comp_mask; }; pci_name The PCI name of the required device. flags A bitwise OR of the various values described below. *MLX5DV_VFIO_CTX_FLAGS_INIT_LINK_DOWN*: Upon device initialization link should stay down. comp_mask Bitmask specifying what fields in the structure are valid.

Returns a NULL-terminated array of devices based on input attr.

mlx5dv_get_vfio_device_list - Get list of available devices to be used over VFIO

Client code should open all the devices it intends to use with ibv_open_device() before calling ibv_free_device_list(). Once it frees the array with ibv_free_device_list(), it will be able to use only the open devices; pointers to unopened devices will no longer be valid.

Returns the array of the matching devices, or sets errno and returns NULL if the request fails.
