💅 gmc_v8_0_flush_gpu_tlb_pasid(9) — tlb flush via pasid

okay so bestie, we're deep in the Kernel API Manual today, and this one is literally a lil' function that clears out the TLB for one specific PASID 🎀 no cap, that's the whole vibe. let's get into it ✨

✨ NAME ✨

gmc_v8_0_flush_gpu_tlb_pasid — tlb flush via pasid 🦋

🌸 SYNOPSIS 🌸

void gmc_v8_0_flush_gpu_tlb_pasid (struct amdgpu_device *adev , uint16_t
pasid , uint32_t flush_type , bool all_hub , uint32_t inst );

like… five whole arguments, she's highkey doing the most 😭 but it's fine, we go through them one by one 💖

🎀 ARGUMENTS 🎀

  • adev — your amdgpu_device pointer, aka the whole GPU situation 👑
  • pasid — the pasid to be flush 🫧 (yes bestie, that's the one getting flushed)
  • flush_type — the type of flush, iykyk 💅
  • all_hub — flush all hubs ⭐ like, every single hub, no crumbs left
  • inst — is used to select which instance of KIQ to use for the invalidation 🔥 (picking your fighter, fr fr)

🌈 DESCRIPTION 🌈

Flush the TLB for the requested pasid. periodt. 💀✨

that's it, that's the description — she's short, she's sweet, she's an icon, and she does exactly one (1) job: nuking the TLB entries for the pasid you asked about and nothing else 🙈

🦋 SEE ALSO 🦋

Kernel file ./drivers/gpu/drm/amd/amdgpu/gmc_v8_0.c — the mothership, go read her 💜

and the whole friend group:

ngl bestie, take the pasid and hub stuff seriously — this is real kernel code, not a vibe 🌸
