STRUCT TEGRA241_VINTF(9)

💅 struct tegra241_vintf(9) — Kernel API Manual

okay so bestie, welcome to the Virtual Interface page 💖 this is struct tegra241_vintf from the Kernel API Manual and it's honestly kind of the main character of the CMDQV situation. let's get into it ✨

---

✨ SYNOPSIS ✨

here's the whole vibe, copied exactly, no cap:

struct tegra241_vintf {
    struct arm_vsmmu vsmmu;
    u16 idx;
    bool enabled;
    bool hyp_own;
    struct tegra241_cmdqv *cmdqv;
    struct tegra241_vcmdq **lvcmdqs;
    struct mutex lvcmdq_mutex;
    void __iomem *base;
    unsigned long mmap_offset;
    struct ida sids;
 };

like, she's got range 🎀 and yes the trailing }; is indented like that in the original, we don't judge, we respect 🫶

🦋 Members 🦋

let's do a member-by-member vibe check, one bullet each, nobody gets left behind 💜

• vsmmu — the embedded arm_vsmmu structure. she's living inside, it's giving nested-struct realness 😭
• idx — global index in the CMDQV. literally just her number in the group chat 🔥
• enabled — enable status. is she on or is she off, that's the whole question 👑
• hyp_own — owned by hypervisor (in-kernel). so like, the hypervisor is her parent, in-kernel specifically, iykyk 🧚
• cmdqv — parent CMDQV pointer. every icon has a parent 💅
• lvcmdqs — list of logical VCMDQ pointers. a whole list of them, ** and everything, obsessed ⭐
• lvcmdq_mutex — lock to serialize user-allocated lvcmdqs. safety first bestie, no chaotic concurrent energy allowed 🌸
• base — MMIO base address. that's the void __iomem * one, respect the __iomem 🙈
• mmap_offset — offset argument for the mmap syscall. yes, that mmap syscall, the actual one 💀
• sids — stream ID mapping resources. a struct ida full of stream IDs, slay 🍓

🔥 SEE ALSO 🔥

go read these next, fr fr, the lore is deep:

• Kernel file ./drivers/iommu/arm/arm-smmu-v3/tegra241-cmdqv.c
• struct tegra241_vcmdq(9)
• struct tegra241_vintf_sid(9)
• struct tegra241_cmdqv(9)

---

ngl that whole SEE ALSO list is a little reading rainbow situation 🌈 but you got this bestie, one struct at a time 💖

okay that's the whole page, mwah 🎀 this came from ./drivers/iommu/arm/arm-smmu-v3 and it's dated October 2026, and yes the footer also says struct tegra241_vintf(9) again because the manpage said it twice and we keep every detail, periodt ✨💅
