STRUCT BCM2835_DMADEV(9)

💖 NAME 💖

okay so bestie, this is struct bcm2835_dmadev(9) from the Kernel API Manual — it's literally the BCM2835 DMA controller struct and she's iconic ✨

🌸 SYNOPSIS 🌸

       struct bcm2835_dmadev {
           struct dma_device ddev;
           void __iomem *base;
           dma_addr_t zero_page;
        };

• ddev — the DMA device, periodt 💅
• base — base address of the register map, no cap 📍
• zero_page — bus address of the zero page (this one's lowkey doing detective work: it detects transactions copying from the zero page and avoids accessing memory if so) 🔍✨

🦋 SEE ALSO 🦋

• Kernel file ./drivers/dma/bcm2835-dma.c
• bcm2835_dma_create_cb_chain(9)

and that's the whole vibe 🎀 this cutie lives under ./drivers/dma, dated October 2026, and she's still out here being struct bcm2835_dmadev(9) — slay, fr fr 💜👑
