ENUM PCI_EPC_AUX_RESOURCE_TYPE(9)

💖 enum pci_epc_aux_resource_type(9) 💖

okay bestie, this is straight out of the Kernel API Manual — we're talking enum pci_epc_aux_resource_type, and it's giving auxiliary resource type identifiers. no cap, this one is short and iconic.

✨ NAME ✨

enum pci_epc_aux_resource_type — auxiliary resource type identifiers

🎀 SYNOPSIS 🎀

enum pci_epc_aux_resource_type {
    PCI_EPC_AUX_DOORBELL_MMIO

};

🌸 Constants 🌸

• PCI_EPC_AUX_DOORBELL_MMIO — Doorbell MMIO, that might be outside the DMA controller register window 👀🔥

🫶 Description 🫶

okay so here's the tea: EPC backends may expose auxiliary blocks (e.g. DMA engines) by mapping their register windows and descriptor memories into BAR space. This enum identifies the type of each exposable resource. literally that's the whole vibe — it's the label maker for each exposable resource type 💅
