amdgpu_devi..._job_running(9)

🎀 amdgpu_devi..._job_running(9) 🎀

okay so this is a page from the Kernel API Manual (yes, that Kernel API Manual 💅) and it's all about one tiny little boolean function that has a lot of feelings. hang with me bestie, it's short but it matters.

---

✨ NAME ✨

amdgpu_device_has_job_running — literally just check if there is any unfinished job 👀 like, is anything still cooking on this GPU or nah

---

🌸 SYNOPSIS 🌸

bool amdgpu_device_has_job_running (struct amdgpu_device *adev );

it returns a bool, she takes one argument, she's lowkey iconic like that 🫶

---

🦋 ARGUMENTS 🦋

• adev — amdgpu_device pointer. that's it. that's the whole argument. it's giving minimalism ✨

---

💜 DESCRIPTION 💜

so here's the vibe check: this function checks if there is any job running on the device when the guest driver receives an FLR notification from the host driver. 🧚

and why do we care?? because if there are still jobs running, then the guest driver will not respond to the FLR reset. nope. not today. 🙈 instead, the move is to let the job hit the timeout, and then the guest driver issues the reset request. main character problem-solving energy, fr fr 💅

no cap, the "just let it time out" part is the whole personality of this function — don't expect an immediate FLR response if jobs are still in flight 😭
