💅 NAME 💅

okay so bestie, sdma_v7_1_inst_load_microcode — it's the one that loads the sDMA ME ucode. that's it. that's the whole job. and honestly? it does it flawlessly. periodt. ✨

this little icon lives in the Kernel API Manual, iykyk 🎀

🦋 SYNOPSIS 🦋

int sdma_v7_1_inst_load_microcode (struct amdgpu_device *adev , uint32_t
inst_mask );

like look at her. tiny. powerful. main character energy fr fr. 💜

🌸 ARGUMENTS 🌸

• adev — an amdgpu_device pointer. your device. your whole entire GPU situation. she needs to know who we're loading ucode for, okay?? 🫶
• inst_mask — a mask of which dma engine instances you want enabled. it's giving "pick your faves" energy. mask on, mask off, your choice. 💅

---

✨ DESCRIPTION ✨

so basically: this function loads the sDMA0/1 ucode. that's it. that's the mission. and she nails it. 👑

returns 0 for success — slay, we love a clean return 🎀 — or -EINVAL if the ucode isn't available. and yeah, if it's not available, she can't load it. that's literally just how it is bestie. 😭 no ucode, no vibe. it's giving "the file said no". 💀

ngl, the -EINVAL is your red flag moment — the ucode you were expecting to be there? not there. check yourself before you wreck your resume. 🙈
