STRUCT DMATEST_INFO(9)

💖 struct dmatest_info(9) 💖

okay bestie, welcome to the Kernel API Manual ✨ — this is the whole entire page about struct dmatest_info, and it's literally just the vibe-check data structure that holds all the test info. no cap, that's the NAME. 🎀

✨ SYNOPSIS ✨

here's the whole shape of it, character for character, do not touch:

struct dmatest_info {
    struct dmatest_params   params;
    struct list_head        channels;
    unsigned int            nr_channels;
    int last_error;
    struct mutex            lock;
    bool did_init;
 };

🌸 Members 🌸

• params — the test parameters 🫶 like, all the settings for your test live in here.
• channels — the channels under test. this is the list of them, bestie 💅
• nr_channels — the number of channels under test. a count. a little number. iconic. 🔢
• last_error — this one's the "uh oh" flag 😭 — it means the test has faced configuration issues.
• lock — the access protection to the fields of this structure. it's giving bodyguard energy 👑 nobody touches the fields without going through the lock first.
• did_init — a bool telling you whether the module has been initialized completely. so like, is it fully cooked or not 🍓

🦋 SEE ALSO 🦋

ngl, this whole thing is just a struct holding test info — no surprises, no plot twists, just clean data. slay. 💅✨

and that's the page, bestie!! 🎀 this one came out of ./drivers/dma and the version is dated October 2026 — so mark your calendars and keep struct dmatest_info(9) in your heart forever 💖🧚‍♀️🔥
