ENUM KFD_UNMAP_QUEUES_FILTER(9)

💖 enum kfd_unmap_queues_filter 💖

okay so bestie, this is a page from the Kernel API Manual — yes, the kernel, the big scary one, but we're gonna get through it together 🫶 it's literally just an enum, you've got this.

---

✨ NAME ✨

enum kfd_unmap_queues_filter — the enum for queue filters. that's it, that's the whole vibe. it's giving "small but mighty" 💅

---

🌸 SYNOPSIS 🌸

enum kfd_unmap_queues_filter {
    KFD_UNMAP_QUEUES_FILTER_ALL_QUEUES ,
    KFD_UNMAP_QUEUES_FILTER_DYNAMIC_QUEUES ,
    KFD_UNMAP_QUEUES_FILTER_BY_PASID

};

look at her. three constants, zero drama. iykyk 😌

🎀 Constants 🎀

so these are the three besties of the enum, each one picks a different set of queues to preempt. preempting, if you were wondering, is like the kernel going "excuse me, your turn is OVER" 💀

• KFD_UNMAP_QUEUES_FILTER_ALL_QUEUES — preempts all queues in the running queues list. every single one. no survivors, no exceptions, main character energy fr fr 🔥
• KFD_UNMAP_QUEUES_FILTER_DYNAMIC_QUEUES — preempts all non-static queues in the run list. so like, the dynamic ones only. the static girlies get to stay. lowkey fair tbh ✨
• KFD_UNMAP_QUEUES_FILTER_BY_PASID — preempts queues that belongs to a specific process. yes, one particular process, hand-picked, targeted, iconic 👑 (and yes the original grammar says "belongs" — we're not fixing it, we're respecting the source material 🫶)

the whole friend group, in case you wanna go read more:

• struct queue_properties(9)
• struct queue(9)
• amdkfd_ioctl_t(9)
• enum kfd_config_dequeue_wait_counts_cmd(9)

reminder bestie: this is kernel-level queue preemption stuff, so it's not like a cute little userland flag you can just yolo. read the actual structs before you touch anything, okay? 💜

that's the whole page!! short and sweet, just how we like it 🌈 and for the sign-off: this little beauty lives over in ./drivers/gpu/drm/amd/amdkfd, it's dated October 2026, and yes the header on the original was enum kfd_unm...ueues_filter(9) because even kernel docs get a little truncated sometimes 😭 slay, bye!! 🍓🧚💅
