STRUCT UACCE_QUEUE(9)

💖 NAME 💖

okay so this is struct uacce_queue(9), and it comes from the Kernel API Manual, bestie. We're folding that manual name in right here so the header line can stay un-copied, periodt. 💅

struct uacce_queue — (the source leaves the description after the dash blank, and I am not gonna invent one, no cap).

✨ SYNOPSIS ✨

Here's the exact struct, copied character-for-character, no vibes-based renaming, fr fr:

       struct uacce_queue {
           struct uacce_device *uacce;
           void *priv;
           wait_queue_head_t wait;
           struct list_head list;
           struct uacce_qfile_region *qfrs[UACCE_MAX_REGION];
           struct mutex mutex;
           enum uacce_q_state state;
           u32 pasid;
           struct iommu_sva *handle;
           struct address_space *mapping;
        };

🎀 Members 🎀

• uacce — pointer to uacce. literally just a pointer to it, bestie 🫶
• priv — private pointer. your lil private pointer moment 🙈
• wait — wait queue head. the wait queue head is here, slay ✨
• list — index into uacce queues list. it's an index into the uacce queues list, iykyk
• qfrs — pointer of qfr regions. pointer of qfr regions, and yes it's the UACCE_MAX_REGION array situation from up top 👀
• mutex — protects queue state. this mutex protects queue state, periodt 🔥
• state — queue state machine. queue state machine energy 💅
• pasid — pasid associated to the mm. pasid associated to the mm, exactly that 🦋
• handle — iommu_sva handle returned by iommu_sva_bind_device. an iommu_sva handle returned by iommu_sva_bind_device 🎀
• mapping — user space mapping of the queue. user space mapping of the queue, iconic 🌸

okay bye bestie — this page's source/version is ./include/linux, it's dated October 2026, and the main character is struct uacce_queue(9). 💖✨🫶
