💅 xgene_chan_xfer_ld_pending — a little intro bestie

okay so this is a page from the Kernel API Manual (manual name, folded in like a little name tag 🎀) and it's about xgene_chan_xfer_ld_pending, which sounds like a spell from a very niche wizard school but is actually a real function. let's get into it, no cap.

✨ NAME ✨

xgene_chan_xfer_ld_pending — push any pending transactions to hw

like, the whole job is literally shoving the queued-up stuff over to the hardware. that's it. that's the vibe. 💅

---

🦋 SYNOPSIS 🦋

void xgene_chan_xfer_ld_pending (struct xgene_dma_chan *chan );

look at her go. returns void — she gives nothing back, she's just doing the work. main character energy fr fr ✨

---

🎀 ARGUMENTS 🎀

• chan — the X-Gene DMA channel. that's your girl right there, the channel you're operating on 🫶

---

🌸 DESCRIPTION 🌸

LOCKING: must hold chan->lock

not me putting this in all caps because it's genuinely all caps in the source 😭 this is a hard requirement, bestie — you must be holding chan->lock when you call this. no lock, no function. it's giving "read the room" but for concurrency. 🔥

foreal foreal, this isn't a suggestion, it's a locking contract. hold chan->lock or don't call it at all 💀
