STRUCT XE_SRIOV_PF_SERVICE(9)

💖 NAME 💖

okay so bestie, gather round — struct xe_sriov_pf_service is literally just Data used by the PF service. that's the whole vibe. it's the little info packet the PF keeps around about itself. no cap.

✨ SYNOPSIS ✨

here's the whole shape of it, exactly as it lives in the kernel, not me paraphrasing one single character 👑

struct xe_sriov_pf_service {
    struct {
      struct xe_sriov_pf_service_version base;
      struct xe_sriov_pf_service_version latest;
    } version;
 };

lowkey it's giving nesting doll energy — a struct inside a struct, and both of the inner ones are struct xe_sriov_pf_service_version. iconic behavior honestly 🎀

🌸 Members 🌸

• version — this is the one and only member, and it's carrying all the info about VF/PF ABI versions for the current platform. it's the main character of this struct fr fr.
  • version.base — the lowest VF/PF ABI version that could be negotiated with the VF. think of it as the floor, the bare minimum handshake the PF is willing to do 🫶
  • version.latest — the latest VF/PF ABI version supported by the PF driver. that's the ceiling bestie, the freshest thing the PF knows how to speak ⭐

so yeah — base down low, latest up high, and somewhere in between is the version they'll actually agree on. iykyk 💅
