qed_iov_config_perm_table(9)

💅 NAME 💅

qed_iov_config_perm_table — ok so this is the function that configures the permission zone table ✨ literally its whole job 🎀

---

🌸 SYNOPSIS 🌸

void qed_iov_config_perm_table (struct qed_hwfn *p_hwfn , struct qed_ptt
* p_ptt , struct qed_vf_info *vf , u8 enable );

bestie it returns void, so like… don't go looking for a return value, there isn't one 🫶

---

🦋 ARGUMENTS 🦋

• p_hwfn — the HW device data 💖 that's your hardware function handle, your main character struct.
• p_ptt — the PTT window for writing the registers ✨ this is the window you poke the registers through, no window no writing, periodt.
• vf — the VF info data 👑 all the deets about this particular virtual function.
• enable — the actual permission for this VF 🌈 typed as a u8, it's literally the permission value you're setting. the real one. the actual one.

⭐ DESCRIPTION ⭐

okay so here's the lore 🧚 in E4, the queue zone permission table size is 320x9. not 319, not 321. 320x9. write that down 💀

and there are 320 VF queues for a single engine device — but heads up, it's 256 for dual engine device 🙈 so the count is not the same everywhere, iykyk.

each entry has the following format: {Valid, VF[7:0]} 🔥 so that's a Valid field plus the VF field going from bit 7 down to bit 0, no cap.
