💖 acpi_dma_parse_fixed_dma(9) 💖

okay so bestie, welcome to the Kernel API Manual — this page is literally all about turning ACPI FixedDMA resources into a DMA specifier, and it's giving very niche, very iconic kernel energy. no cap, it's a small function but it's doing Real Work. 🎀

✨ NAME ✨

acpi_dma_parse_fixed_dma — parse FixedDMA ACPI resources into a DMA specifier. that's the whole vibe. it reads the resource, it hands you back a specifier. slay. 💅

🌸 SYNOPSIS 🌸

int acpi_dma_parse_fixed_dma (struct acpi_resource *res , void *data );

🦋 ARGUMENTS 🦋

• res — the struct acpi_resource you're pulling FixedDMA resources out of. that's your source material, your main character. 🔥
• data — a pointer to a helper struct, struct acpi_dma_parser_data. it's the little buddy that carries stuff around for the parsing. 🫶

ngl, if you're here you're probably deep in drivers/dma territory, and honestly? respect. 🧚

that's the page, bestie!! this one lives in ./drivers/dma, and the version vibes are dated October 2026 — so mark your calendars, screenshot it, put it on the fridge. 🌈💖 mwah, go parse some resources! 🍓✨
