πŸ’… amdgpu_vmid_reset(9)

okay so bestie, welcome to the Kernel API Manual β€” this one's a tiny little function page and honestly it's giving "short but important" energy. It lives in the kernel docs, and we're gonna go through it together, no cap. πŸŽ€


✨ NAME ✨

amdgpu_vmid_reset β€” reset VMID to zero

that's it, that's the whole name section. iconic brevity. πŸ‘‘


🌸 SYNOPSIS 🌸

void amdgpu_vmid_reset (struct amdgpu_device *adev , unsigned vmhub ,
       unsigned vmid );

so it returns void, meaning it literally gives nothing back β€” no return value, no drama, it just does the thing. πŸ’…


πŸ¦‹ ARGUMENTS πŸ¦‹

  • adev β€” the amdgpu device structure. like, the whole device, bestie. it's the main character of this call. 🌟
  • vmhub β€” the vmhub type. yes, that's exactly as vague as the original is, and we're respecting it. 🫢
  • vmid β€” the vmid number to use. the actual number you're handing over. πŸ”’

πŸ’– DESCRIPTION πŸ’–

okay so here's the tea: this function resets saved GDW, GWS and OA β€” all three, together, on purpose β€” and the whole point is to force a switch on the next flush. that's the vibe. nothing more, nothing less. it's a clean slate moment. ✨

no hidden caveats, no warning labels, no "don't do this at home" β€” just a straight-up reset. periodt. πŸ’€
