adf_recv_vf2pf_msg(9)

💖 adf_recv_vf2pf_msg(9) — like, the Kernel API Manual page you actually wanna read 💖

okay bestie, so this one lives in the Kernel API Manual (section 9, that's the kernel-functions girlies 🧚) and it's literally all about the PF catching a message from a VF. stay with me, it's gonna slay ✨

🌸 NAME 🌸

adf_recv_vf2pf_msg — receive a VF to PF message 🫶

✨ SYNOPSIS ✨

struct pfvf_message adf_recv_vf2pf_msg (struct adf_accel_dev *accel_dev
, u8 vf_nr );

that's the whole vibe check right there — it hands you back a struct pfvf_message. no cap 💅

🎀 ARGUMENTS 🎀

• accel_dev — Pointer to acceleration device. yeah, the accel dev itself, the main character of this whole situation 👑
• vf_nr — Number of the VF from where the message will be received. like, which VF is sending you mail, bestie 📬

🦋 DESCRIPTION 🦋

the way that this function just lets the PF receive a message from a specific VF 😭 that's it. that's the whole job. PF on one side, one very specific VF on the other, message goes through. iconic behaviour, honestly.

🔥 RETURN 🔥

• a valid message on success 💖
• zero otherwise 💀

so like — got a message? valid. no message? zero. simple as. periodt.

🌈 SEE ALSO 🌈

• Kernel file ./drivers/crypto/intel/qat/qat_common/adf_pfvf_pf_proto.c — yeah, go read the source, iykyk 🧚
• adf_send_pf2vf_msg(9) — the other direction bestie, the send side 🫶
• adf_enable_pf2vf_comms(9) — turn the comms on first, obviously ✨
