radeon_acpi...st_supported(9)

💅 radeon_acpi_is_pcie_performance_request_supported(9)

okay so welcome to the Kernel API Manual, bestie — yes the actual manual name, we're in the kernel docs now, very main character energy 🎀

---

✨ NAME ✨

radeon_acpi_is_pcie_performance_request_supported — and that's it. That's the whole name section. No little tagline, no description, nothing. It just drops the function name and leaves 💀 iconic minimalism honestly.

---

🦋 SYNOPSIS 🦋

bool radeon_acpi_is_pcie_performance_request_supported (struct
       radeon_device *rdev );

so it returns a bool, it takes one arg, that's the whole vibe check 🫶

---

🌸 ARGUMENTS 🌸

• rdev — a radeon_device pointer. literally just a pointer to your radeon device, no cap ✨

---

💖 DESCRIPTION 💖

okay so this one is a little checker function and it's lowkey important 👑

It checks whether the ATCS pcie_perf_req and pcie_dev_rdy methods are supported — on all asics, no exceptions, everybody's invited to this party 🌈

If they're supported it returns true. If not, false. That's the whole plot, fr fr 🎯
