STRUCT SMEM_PARTITION(9)

💖 struct smem_partition(9) 💖

okay so this is the Kernel API Manual entry for struct smem_partition(9) — literally the little struct that describes an smem partition. Bestie, it’s giving “small but important kernel data structure” energy, and we’re gonna read it together. 🎀

✨ NAME ✨

struct smem_partition — describes smem partition. That’s the whole name vibe: it’s a struct, and it describes an smem partition. iconic. 💅

🦋 SYNOPSIS 🦋

       struct smem_partition {
           void __iomem *virt_base;
           phys_addr_t phys_base;
           size_t cacheline;
           size_t size;
        };

💅 Members 💅

These are the four fields, and yes, we’re listing every single one because we do not skip. 🫶

• virt_base — the starting virtual address of the partition. like the partition’s virtual-address origin point ✨
• phys_base — the starting physical address of the partition. the physical-address origin point, matching energy 💫
• cacheline — the alignment for "cached" entries. yes, with the quotes, that’s the detail 🎀
• size — size of the partition. literally the size, no plot twist 💀

okay bestie, if u wanna go deeper (and we know u do), the kernel file to peek at is ./drivers/soc/qcom/smem.c. Also these iconic references are right there in the manual: struct smem_proc_comm(9), struct smem_global_entry(9), struct smem_header(9), struct smem_ptable_entry(9), struct smem_ptable(9), struct smem_partition_header(9), struct smem_private_entry(9), struct smem_info(9), struct smem_region(9), struct qcom_smem(9), qcom_smem_bust_hwspin_lock_by_host(9), qcom_smem_is_available(9), qcom_smem_alloc(9), qcom_smem_get(9), qcom_smem_get_free_space(9), qcom_smem_virt_to_phys(9), qcom_smem_get_soc_id(9), qcom_smem_get_feature_code(9).

that’s the whole page, bestie. source/version: ./drivers/soc/qcom; date: October 2026. go forth and slay ur kernel reading 💅💖
