gsi_trans_read_byte(9)

💖 NAME 💖

Okay bestie, welcome to the Kernel API Manual page for gsi_trans_read_byte(9) ✨. This function issues a single byte read TRE on a channel — that's the whole gig, and it ate 💅.

✨ SYNOPSIS ✨

int gsi_trans_read_byte (struct gsi *gsi , u32 channel_id , dma_addr_t
       addr );

🫶 ARGUMENTS 🫶

• gsi — the GSI pointer, your main character here 👑.
• channel_id — the channel on which to read a byte, slay 💖.
• addr — the DMA address into which to transfer the one byte, periodt ✨.

🦋 DESCRIPTION 🦋

Plot twist, bestie: this is not a transaction operation at all 😭. It's defined here because it needs to be done in coordination with other transaction activity. That's the vibe — lowkey important, highkey not a transaction op 🙈.
