Okay bestie, welcome to the glow-up zone ✨ This is the page for ishtp_hbm_dma_xfer_ack(9) from the Kernel API Manual, and it’s literally about catching an ACK. No cap.

🌸 NAME 🌸

ishtp_hbm_dma_xfer_ack — Receive transfer ACK. That’s the whole errand, babe 🫶

✨ SYNOPSIS ✨

void ishtp_hbm_dma_xfer_ack (struct ishtp_device *dev , struct
       dma_xfer_hbm *dma_xfer );

Lowkey iconic signature, highkey exact. Don’t touch the spacing, iykyk 💅

🎀 ARGUMENTS 🎀

• dev — ISHTP device instance. It’s the main-character device energy 👑
• dma_xfer — HBM transfer message. This is the message carrying the transfer vibes.

💫 DESCRIPTION 💫

Receive ack for ISHTP-over-DMA client message. That’s it, that’s the function — it catches the acknowledgment for the ISHTP-over-DMA client message and does its little kernel thing 💖

No extra lore here, bestie: the original page keeps this description short and sweet. Respect.
