STRUCT QCOM_SMEM(9)

✨ struct qcom_smem(9) ✨

okay bestie, so this is struct qcom_smem from the Kernel API Manual (the qcom_smem(9) girly herself 💅), and she's literally the device data for the smem device. no cap. she's giving main character energy in a shared-memory kind of way and we're gonna learn her together 🫶

🌸 NAME 🌸

struct qcom_smem — device data for the smem device ✨

---

🎀 SYNOPSIS 🎀

struct qcom_smem {
    struct device *dev;
    struct hwspinlock *hwlock;
    u32 item_count;
    struct platform_device *socinfo;
    struct smem_ptable *ptable;
    struct smem_partition global_partition;
    struct xarray partitions;
    struct dentry *debugfs_dir;
    unsigned int num_regions;
    struct smem_region regions[];
 };

like... look at her. iconic. 🔥

go read the actual kernel file before you @ me, bestie — the struct is only half the story 📖✨

okay that's the whole page!! sign-off time: this little beauty lives under ./drivers/soc/qcom, dated October 2026, and it's the struct qcom_smem(9) page. slay, study her, and you're gonna eat this exam fr fr 💜🌈🎀
