STRUCT NFP_NET_VF(9)

💅 struct nfp_net_vf(9) — Kernel API Manual 💅

Okay bestie, this is the kernel API manual page for struct nfp_net_vf, aka the NFP VF-specific device structure. It’s giving “small struct, very specific job,” and we’re gonna read it together. 🦋

✨ NAME ✨

struct nfp_net_vf — NFP VF-specific device structure. Periodt.

🎀 SYNOPSIS 🎀

Here’s the struct exactly as it rolls, no cap:

       struct nfp_net_vf {
           struct nfp_net *nn;
           struct msix_entry irq_entries[NFP_NET_NON_Q_VECTORS +
       NFP_NET_MAX_TX_RINGS];
           u8 __iomem *q_bar;
           struct dentry *ddir;
        };

💖 Members 💖

Okay so this struct has four members, and each one is doing its own little thing:

• nn — the NFP Net structure for this device. Main character energy for the device itself, fr fr. 💅
• irq_entries — a pre-allocated array of MSI-X entries. Think pre-booked VIP seating for interrupts ✨. Its size is NFP_NET_NON_Q_VECTORS + NFP_NET_MAX_TX_RINGS.
• q_bar — pointer to mapped QC memory. Important caveat bestie: it’s NULL if TX/RX are mapped directly. So if you see NULL, that’s literally why. 😭
• ddir — per-device debugfs directory. Your little debugfs home base 🎀.
