STRUCT SCA3000_STATE(9)

💖 struct sca3000_state(9) 💖

okay so bestie, this is a page from the Kernel API Manual and honestly? it's giving "underrated little struct that holds the whole vibe together" energy. let's get into it 🫶

---

✨ NAME ✨

struct sca3000_state — literally just device instance state information. the receipts, the lore, the state of the device. that's her 💅

---

🦋 SYNOPSIS 🦋

here's the actual shape of her, and yes we're keeping it exactly like this, no edits no cap:

struct sca3000_state {
    struct spi_device               *us;
    const struct sca3000_chip_info  *info;
    int mo_det_use_count;
    struct mutex                    lock;
    u8 rx[384];
    u8 tx[6];
};

like... look at her. iconic. 🌸

🎀 Members 🎀

breaking down the squad one by one, bestie:

• us — the associated spi device. her plus-one, her ride-or-die connection 💖
• info — chip variant information. all the deets about which chip we're dealing with, iykyk
• mo_det_use_count — reference counter for the motion detection unit. keeping track of how many people are using the motion detection unit, like a little attendance sheet 😭
• lock — the lock used to protect elements of sca3000_state and the underlying device state. she's the bouncer at the club, nobody gets in without her say-so 🔥
• rx — dma-able receive buffer. incoming data, bestie, and it's dma-able so she goes fast ✨
• tx — dma-able transmit buffer. outgoing data, same deal, dma-able and ready to slay 💫
