STRUCT XDMA_DESC_BLOCK(9)

🎀 NAME 🎀

okay so bestie, this is the struct xdma_desc_block(9) page from the Kernel API Manual — and it's literally giving Descriptor block energy 💅. The name is struct xdma_desc_block, and the whole vibe is just: Descriptor block ✨.

✨ SYNOPSIS ✨

here's the icon in code form, exactly as the manual drops it:

struct xdma_desc_block {
    void *virt_addr;
    dma_addr_t dma_addr;
 };

💅 Members 💅

this struct is serving two fields and a dream 🎀:

• virt_addr — Virtual address of block start
• dma_addr — DMA address of block start
