💅 bam_init(9) — a Kernel API Manual moment 🎀

ok so bestie, we're in the Kernel API Manual today and the star of the show is bam_init(9). yes it's a real section 9 manpage, yes we're gonna read it together, no you cannot skip it 💖

✨ NAME ✨

bam_init —

so like... the name field is literally just vibing there with nothing after the dash 🙈 that's not me being lazy, that's genuinely how the page is written. the description slot is empty. a mystery. a blank canvas. main character energy but make it silent 🫶

⭐ SYNOPSIS ⭐

int bam_init (struct bam_device *bdev );

it returns an int, it takes exactly one thing, and that thing is a <italic>bdev</italic>. short and iconic, honestly 💅

🌸 ARGUMENTS 🌸

  • bdev — the bam device. that's it. that's the whole argument. it's a struct bam_device * and it's the one (1) thing you gotta hand over 💜

🦋 DESCRIPTION 🦋

ok so real talk: this one is an initialization helper for the global bam registers ✨ it's the "get the global stuff set up" function — not the channels, not the transfers, the global registers. lowkey the opening act before everything else gets its moment 👑

🔥 SEE ALSO 🔥

first up, the source file itself lives right here in the kernel tree:

Kernel file ./drivers/dma/qcom/bam_dma.c

and now the whole friend group, in the exact order the page gives them — no cap, all of these are listed:

that's nineteen functions, bestie, and every single one of them made the list 🌈 go read them, iykyk

ngl there's no explicit return-value section and no error list on this page, so i'm not gonna invent one for you 🫶 what you see is what's on the page, periodt.

and that's the whole page!! 💀 literally the shortest read ever, you ate that. this edition comes courtesy of ./drivers/dma/qcom and it's dated October 2026 — so like, mark your calendar queen, see you then 👑💖
