xe_gt_sriov...nfig_get_dbs(9)

💅 NAME 💅

okay so bestie, welcome to the Kernel API Manual ✨ — this one's about xe_gt_sriov_pf_config_get_dbs — the little function that gets a VF's GuC doorbells IDs quota. that's it, that's the whole vibe 🎀

---

🦋 SYNOPSIS 🦋

u32 xe_gt_sriov_pf_config_get_dbs (struct xe_gt *gt , unsigned int vfid );

like, that's the whole signature. copy it exact, no cap 🫶

---

🌸 ARGUMENTS 🌸

• gt — the xe_gt 🚪 like the actual GT object you're poking at
• vfid — the VF identifier 🔢 which VF are we talking about bestie

---

💖 DESCRIPTION 💖

okay so here's the tea ☕ — this function can only be called on PF. that's a real rule, not a suggestion, periodt 💀

and if vfid happens to represent a PF, then what comes back is the number of PF's spare GuC doorbells IDs. literally that's it. iconic behavior, no notes ✨

---

🔥 RETURN 🔥

you get back the VF's quota — or, in the PF case, the PF's spare. whichever one applies, slay 💅
