ENUM KFD_QUEUE_TYPE(9)

💅 enum kfd_queue_type(9) 💅

okay so this is a page straight out of the Kernel API Manual bestie, and it's literally just the enum that lists every queue type a KFD queue can be. that's the whole vibe. let's get into it 🫶

✨ NAME ✨

enum kfd_queue_type — the enum for various queue types. yes queen, that's it, that's the summary ✨

🦋 SYNOPSIS 🦋

enum kfd_queue_type {
    KFD_QUEUE_TYPE_COMPUTE ,
    KFD_QUEUE_TYPE_SDMA ,
    KFD_QUEUE_TYPE_HIQ ,
    KFD_QUEUE_TYPE_SDMA_XGMI ,
    KFD_QUEUE_TYPE_SDMA_BY_ENG_ID ,
    KFD_QUEUE_TYPE_MAX

};

look at her go 💅 six constants, all in a row, no cap.

🎀 Constants 🎀

• KFD_QUEUE_TYPE_COMPUTE — the regular user mode queue type. the main character energy of queue types honestly 🌟
• KFD_QUEUE_TYPE_SDMA — the SDMA user mode queue type. iconic, does what it says 💖
• KFD_QUEUE_TYPE_HIQ — the HIQ queue type. short, sweet, slay 💜
• KFD_QUEUE_TYPE_SDMA_XGMI — a special SDMA queue, specifically for the XGMI interface. fancy 😌✨
• KFD_QUEUE_TYPE_SDMA_BY_ENG_ID — an SDMA user mode queue that's targeted by SDMA engine ID. iykyk 🦋
• KFD_QUEUE_TYPE_MAX — -- undescribed -- 😭 yeah bestie the docs literally say nothing about this one. not me leaving it exactly as-is 🙈

fr fr don't go inventing a meaning for KFD_QUEUE_TYPE_MAX — the manpage itself gives you nothing, and i'm not about to make something up 💀
