STRUCT VIRTCHNL2_QUEUE_VECTOR_MAPS(9)

💖 NAME 💖

bestie, welcome to the struct virtchnl2_queue_vector_maps(9) page in the Kernel API Manual — yes, it’s that kernel-API manual energy, and this struct is literally Map/unmap queues info. 💅

🦋 SYNOPSIS 🦋

okay so here’s the shape of it, character-for-character:

struct virtchnl2_queue_vector_maps {
    __le32 vport_id;
    __le16 num_qv_maps;
    u8 pad[10];
    struct virtchnl2_queue_vector qv_maps[];
};

🌸 Members 🌸

• vport_id — Vport id. that’s the whole note, bestie.
• num_qv_maps — Number of queue vector maps. count those maps, periodt.
• pad — Padding. it’s giving “we reserved some space” energy, no thoughts.
• qv_maps — Queue to vector maps. the actual queue-to-vector map payload, iykyk.

💅 Description 💅

So the PF sends this message to map or unmap queues to vectors and interrupt throttling rate index registers. The external data buffer contains a virtchnl2_queue_vector_maps structure, and that structure contains num_qv_maps of virtchnl2_queue_vector structures. Then CP maps the requested queue vector maps after validating the queue and vector ids and returns a status code. that’s the flow, no cap.

It’s associated with VIRTCHNL2_OP_MAP_QUEUE_VECTOR and VIRTCHNL2_OP_UNMAP_QUEUE_VECTOR. ✨
