💅 adf_send_pf2vf_msg — bestie's guide to the kernel API manual, bestie

okay so picture this: it's a whole kernel API manual page, the title is adf_send_pf2vf_msg(9), and the vibe is "the PF has something to say and the VF is gonna hear it." main character energy fr fr 🫶

✨ NAME ✨

adf_send_pf2vf_msg — send PF to VF message 💌

🌸 SYNOPSIS 🌸

int adf_send_pf2vf_msg (struct adf_accel_dev *accel_dev , u8 vf_nr ,
struct pfvf_message msg );

bestie look at that signature. three things go in, one int comes out. that's it, that's the whole function 🎀

🦋 ARGUMENTS 🦋

• accel_dev — pointer to the acceleration device, aka the whole reason we're here. hand it over and we're cookin' 🔥
• vf_nr — the VF number, like which VF is getting the message. a u8, so keep it cute and small ✨
• msg — the message itself, a struct pfvf_message. the actual ✨content✨ being delivered 🍓

💜 DESCRIPTION 💜

so here's the tea: this function lets the PF send a message to a specific VF. that's the whole thing. no cap. one PF, one chosen VF, one message sliding into its inbox 😭💅

it's giving "passing notes in class but make it kernel." iconic behavior honestly 👑

💖 RETURN 💖

• 0 on success 🎉 (slay)
• an error code otherwise 💀 (not slay, but at least you know)

🌈 SEE ALSO 🌈

• Kernel file ./drivers/crypto/intel/qat/qat_common/adf_pfvf_pf_proto.c — go read it, iykyk 📖
• adf_recv_vf2pf_msg(9) — the other direction bestie, the reply arc 🫶
• adf_enable_pf2vf_comms(9) — you kinda need comms enabled first, just saying ✨

🧚 reminder: 0 is the good ending. anything else means the message did not land, and no amount of manifesting will change your return value 💀

okay that's the page!! mwah 💋 source/version is that cheeky ./drivers/crypto/intel/qat/qat... path and the date on the calendar is October 2026 — put it in your planner, bestie, and stay iconic out there 👑💜
