🌸 NAME 🌸

smu_reset_sdma_is_supported — literally just checks if the SMU can reset the SDMA engine. that's the whole vibe. 🦋

---

✨ SYNOPSIS ✨

bool smu_reset_sdma_is_supported (struct smu_context *smu );

copy it exactly like that, spacing and all, no cap 🙈

🫶 ARGUMENTS 🫶

• smu — a smu_context pointer. that's it. that's the argument. she's a pointer to the smu context and she knows it 👑

---

💖 DESCRIPTION 💖

so like, this function checks whether the SMU supports resetting the SDMA engine. if it's supported it returns true, and if it's not it returns false. literally that simple, no plot twist, no hidden lore 🧚

ngl it's the kind of function that just answers yes or no and then minds her own business. icon behavior honestly ⭐
