💖 pci_ide_stream_setup(9) 💖

okay so this page is from the Kernel API Manual, and it's literally about programming settings into the Selective IDE Stream registers. bestie, that's the whole vibe. ✨

🎀 NAME 🎀

pci_ide_stream_setup — program settings to Selective IDE Stream registers 💅

---

🌸 SYNOPSIS 🌸

void pci_ide_stream_setup (struct pci_dev *pdev , struct pci_ide *ide );

---

🦋 ARGUMENTS 🦋

• pdev — the PCIe device object, and it's for either a Root Port or an Endpoint Partner Port. yep, both are valid here.
• ide — the registered IDE settings descriptor. that's the settings bundle, no cap.

---

🔥 DESCRIPTION 🔥

so here's the tea: when pdev is a PCI_EXP_TYPE_ENDPOINT, the PCI_IDE_EP partner settings are written to pdev's Selective IDE Stream register block. periodt. 💖

and when pdev is a PCI_EXP_TYPE_ROOT_PORT, the PCI_IDE_RP settings are the ones selected. slay. 👑

lowkey important: those are the two cases the page gives us, so that's the whole story here. 💅
