💅 amdgpu_acpi_is_pcie_performance_request_supported — Kernel API Manual (9)

okay so bestie, welcome to the amdgpu_acpi corner of the kernel 🌸 this one lives in the Kernel API Manual, section 9, and it's literally the vibe-check function for your GPU's ACPI performance-request support. let's go 🎀

---

✨ NAME ✨

amdgpu_acpi_is_pcie_performance_request_supported — and yeah, the original leaves the description blank after the dash, so we're matching that energy exactly: it's giving "name only, no notes" 💅 (the description slot is genuinely empty up there, fr fr, not me being lazy 🙈)

---

🦋 SYNOPSIS 🦋

bool amdgpu_acpi_is_pcie_performance_request_supported(struct amdgpu_device *adev);

---

💖 ARGUMENTS 💖

• adev — an amdgpu_device pointer 🫶 that's it, that's the whole argument list, she's low maintenance.

---

👑 DESCRIPTION 👑

so what does she do? she checks whether the ATCS pcie_perf_req and pcie_dev_rdy methods are supported — and yes, on all asics, no exceptions, everybody gets checked ✨

returns true if it's supported, false if it's not. simple as that. no cap. 🧚

ok real talk: the only things this page guarantees are the two ATCS methods being checked, the bool return, and that it applies to all asics. everything else is vibes 💀
