💅 ppc440spe_ad...ssue_pending(9) 💅

okay so this is a page out of the Kernel API Manual bestie, and it's literally the manual page for ppc440spe_ad...ssue_pending(9). pull up a chair, we're getting into it ✨

🌸 NAME 🌸

ppc440spe_adma_issue_pending — flush all pending descriptors to h/w

like, all of them. flushed. to the hardware. no leftovers, no "oops forgot one" energy 💅

🦋 SYNOPSIS 🦋

void ppc440spe_adma_issue_pending (struct dma_chan *chan );

that's it. that's the whole signature. returns void, so don't be out here expecting a return value, because there isn't one 🎀

🫶 ARGUMENTS 🫶

  • chan — -- undescribed --

and yes bestie, the original page literally says -- undescribed -- for this one 😭 the docs said "we're not telling you" and honestly? iconic of them. it's a struct dma_chan * and that's all the page gives us, so that's all we're passing along. no cap, no invented lore 💀

real talk: don't make up what chan does beyond what's written here — the page is silent on it, so we stay silent too 🙈

👑 SEE ALSO 👑

first up, the kernel file this whole thing lives in:

Kernel file ./drivers/dma/ppc4xx/adma.c

and then the full squad — every single sibling function, no skipping, no summarising, because we don't do that here 🔥:

that's the whole page bestie, short and sweet, and every single reference is accounted for 🌈

and for the cute sign-off: this one's from ./drivers/dma/ppc4xx, dated October 2026 💖 go read it, slay, and don't forget to actually flush your pending descriptors 🎀✨
