STRUCT MLXBF_TMFIFO_VDEV(9)

🦋 struct mlxbf_tmfifo_vdev(9) 🦋

okay so bestie, welcome to the Kernel API Manual — this page is all about struct mlxbf_tmfifo_vdev, aka the structure of the TmFifo virtual device, and it is lowkey iconic. no cap, every field is right here 💅✨

🌸 NAME 🌸

struct mlxbf_tmfifo_vdev — Structure of the TmFifo virtual device. periodt.

✨ SYNOPSIS ✨

       struct mlxbf_tmfifo_vdev {
           struct virtio_device vdev;
           u8 status;
           u64 features;
           struct mlxbf_tmfifo_vring vrings[MLXBF_TMFIFO_VRING_MAX];
           union {
             struct virtio_console_config cons;
             struct virtio_net_config net;
           } config;
           struct circ_buf tx_buf;
        };

💖 Members 💖

• vdev — the virtio device, and inside it the vdev.id.device field carries the VIRTIO_ID_xxx id that distinguishes the virtual device. literally the ID era 🫶
• status — the status of the device. keeping tabs, yk?
• features — the supported features of the device. slay.
• vrings — an array of tmfifo vrings of this device. the whole little squad 🌈
• config — a non-anonymous union for cons and net. it's giving “pick a lane” energy.
• config.cons — virtual console config, and you select it if vdev.id.device is VIRTIO_ID_CONSOLE. console bestie hours 🎀
• config.net — virtual network config, and you select it if vdev.id.device is VIRTIO_ID_NET. network bestie hours 🦋
• tx_buf — tx buffer used to buffer data before writing into the FIFO. it holds the data pre-FIFO, no big deal 💅
