ne_submit_request(9)

💅 ne_submit_request(9) — like, the Kernel API Manual page you actually wanna read 🎀

okay bestie, so this is ne_submit_request from the Kernel API Manual, and it's genuinely not that deep — it submits a command request to a PCI device, and what kind of request it is gets decided by the command type. that's the whole vibe. ✨

---

✨ NAME ✨

ne_submit_request — submit a command request over to the PCI device, based on whatever the command type says it is. sending it off, no cap. 💌

---

🌸 SYNOPSIS 🌸

void ne_submit_request (struct pci_dev *pdev , enum ne_pci_dev_cmd_type
cmd_type , void *cmd_request , size_t cmd_request_size );

she returns void, she takes four things, she's an icon. periodt. 👑

---

🦋 ARGUMENTS 🦋

• pdev — the PCI device you're sending the command to. like, the actual destination of the whole operation. 📬
• cmd_type — the command type of the request being sent to the PCI device. it's giving "what are we even doing here" energy, and it's an enum ne_pci_dev_cmd_type. 🏷️
• cmd_request — the command request payload. the actual contents, the main character of the packet. 💖
• cmd_request_size — the size of the command request payload. a size_t, bestie, because we measure things properly in this house. 📏

---

🌈 CONTEXT 🌈

process context, okay? and listen — this function is called with the ne_pci_dev mutex held. so whoever's calling, they already grabbed that lock. not your job, don't touch it, iykyk. 🔒

fr fr, respect the mutex situation or things get weird.
