💅 amdgpu_gfx_...wait_for_kfd(9)

okay so real talk, this is a page from the Kernel API Manual and it's literally all about one little function that manages the KFD wait period for process isolation. buckle up bestie, it's short but it ate 🎀

✨ NAME ✨

amdgpu_gfx_enforce_isolation_wait_for_kfd — Manage KFD wait period for process isolation 💫

🌸 SYNOPSIS 🌸

void amdgpu_gfx_enforce_isolation_wait_for_kfd (struct amdgpu_device
*adev , u32 idx );

no cap, that's the whole signature. she's void, she takes two things, she doesn't return anything back to you 😌

🦋 ARGUMENTS 🦋

  • adev — amdgpu_device pointer 🫶 like, the device itself, obviously
  • idx — Index of the GPU partition 👑

💖 DESCRIPTION 💖

okay so here's the vibe 🧚 when kernel submissions come in, the jobs are given a time slice. iconic. but once that time slice is up, if there are KFD user queues active, kernel submissions get blocked until KFD has had its time slice. the way that works is so satisfying honestly.

and then! once the KFD time slice is up, KFD user queues are preempted and kernel submissions are unblocked and allowed to run again. slay. everyone gets their turn, it's giving polite mutual cooperation 🔥
