✨ amdgpu_gmc_tmz_set(9) ✨

okay so this is a page straight out of the Kernel API Manual, bestie — it's amdgpu_gmc_tmz_set(9) and it's lowkey iconic for being so short. like, the whole function is basically a vibe check with a void return. we love a no-drama king 👑

🎀 NAME 🎀

amdgpu_gmc_tmz_set — check and set if a device supports TMZ 💅

yes that's literally it. "check and set", two jobs, one function, main character energy fr fr.

🦋 SYNOPSIS 🦋

void amdgpu_gmc_tmz_set (struct amdgpu_device *adev );

not me showing you the exact signature, character for character, because we do NOT paraphrase code in this house 🙈 the void up front means nothing comes back out — it's giving "I do the work and I don't need applause" ✨

🌸 ARGUMENTS 🌸

  • adev — an amdgpu_device pointer 🫶 that's the one and only thing you hand it. the whole device, babe. it needs the device so it has something to check and set the TMZ situation on 💖

⭐ DESCRIPTION ⭐

so what it does: it checks and sets if the device adev supports Trusted Memory Zones (TMZ) 🔥 that's the sentence. that's the whole description. no cap.

(note the original says "if an the device" — iconic typo, but the meaning is clear: this function figures out, for the device adev, whether Trusted Memory Zones are a thing, and sets that accordingly ✨ Trusted Memory Zones, capital letters, so you know it's serious 💅)

ngl this is the kind of function that does one thing and then minds its own business. respect 🎀

💜 SEE ALSO 💜

the lore lives in the kernel file ./drivers/gpu/drm/amd/amdgpu/amdgpu_gmc.c 📁 — that's where you go if you want the whole story.
