acpi_is_root_bridge(9)

🌸 NAME 🌸

okay bestie, welcome to the Kernel API Manual page for acpi_is_root_bridge — it determines whether an ACPI CA node is a PCI root bridge. literally that's the whole mission 💅

✨ SYNOPSIS ✨

int acpi_is_root_bridge (acpi_handle handle );

🎀 ARGUMENTS 🎀

• handle — the ACPI CA node in question. that's the one you're vibe-checking 🫶

💅 NOTE 💅

so like, we could make this API take a struct acpi_device * instead, but for now, it's more convenient to operate on an acpi_handle. no cap, that's the note 📝✨

🦋 SEE ALSO 🦋

• Kernel file ./drivers/acpi/pci_root.c
• acpi_dev_get_pci_dev(9)
