amdgpu_pm_dev_state_check(9)

💅 amdgpu_pm_dev_state_check — like, the whole kernel API manual vibe

okay so bestie, welcome to the amdgpu_pm_dev_state_check(9) page, straight out of the Kernel API Manual ✨ this one's a little check-in function and honestly it's giving bodyguard energy 🫶

---

✨ NAME ✨

amdgpu_pm_dev_state_check — Check if device can be accessed. that's it, that's the whole job 💅

---

🌸 SYNOPSIS 🌸

int amdgpu_pm_dev_state_check (struct amdgpu_device *adev , bool runpm
);

like yes, two arguments, one int coming back at you, no cap 🌈

---

🎀 ARGUMENTS 🎀

• adev — Target device. the main character of this whole situation 👑
• runpm — Check runpm status for suspend state checks. so like, when you set this, it's also doing a vibe check on the runpm status for the suspend state checks 🦋

---

💖 DESCRIPTION 💖

okay so here's the tea 🍓 — this function checks the state of the adev for access. that's the whole plot.

• returns 0 if the device is accessible ✅ slay
• returns a negative error code otherwise 😭 not slay

literally that's it, no hidden lore, no secret extra params, periodt 💀

ngl bestie, always check that return value — a negative error code means the device said "not rn" and you gotta respect that 🙈
