🌸 NAME 🌸

struct mtk_cqdma_vchan — the struct that's literally holding all the info describing a virtual channel (VC). that's it. that's the whole job. and it slays at it. 💅

🦋 SYNOPSIS 🦋

here's the whole thing, character for character, no notes:

struct mtk_cqdma_vchan {
    struct virt_dma_chan vc;
    struct mtk_cqdma_pchan *pc;
    struct completion issue_completion;
    bool issue_synchronize;
};

🎀 Members 🎀

okay so let's go through each one because they all matter, periodt:

• vc — an instance for struct virt_dma_chan. she's the virt_dma_chan girlie of the group. 🧚
• pc — the pointer to the underlying PC. just pointing at her PC bestie, that's the whole thing. 🫶
• issue_completion — the wait for all issued descriptors completited. yes that's the original wording, yes i'm keeping it, it's iconic and i don't make the rules. 😭 literally the "we're waiting on everything we issued" field.
• issue_synchronize — a bool indicating channel synchronization starts. bool!! tiny little true-or-false icon. ⭐

fr fr bestie, don't invent extra meaning for these — the manpage says exactly this and nothing more, and we respect the source. 💀
