DEVICE COMMANDS - PAYLOAD STRUCTURE FOR REQUESTS AND REPLIES.(9)

🧚 Device comm...and replies. — Kernel API Manual, section (9)

okay so bestie, real talk: the title up top literally reads Device comm...and replies.(9) — yes, it's cut off mid-word, and no, we are not fixing it. That's just how it lives in the Kernel API Manual, and it's a section 9 page. Iconic behavior, honestly. 🎀

And what's it about? One line, one vibe: device commands — payload structure for requests and replies. That's the whole thing. It's your cheat sheet for how the request/reply payloads get shaped. That's it, that's the page. 🫶

🌸 SEE ALSO 🌸

bestie this page is basically a SEE ALSO — it's giving "my job here is to point you at the real main characters." So here's the full crew, in order, no skips, no cap. 👑

📁 the kernel file

• the kernel file ./drivers/virt/nitro_enclaves/ne_pci_dev.h — the source of truth, the whole reason we're here 💖

🦋 the device, its registers, and its commands

• Nitro Enclaves (NE) PCI device(9)
• PCI_DEVICE_ID_NE(9)
• PCI_BAR_NE(9)
• Device registers in the NE PCI device MMIO BAR(9)
• NE_ENABLE(9)
• NE_VERSION(9)
• NE_COMMAND(9)
• NE_EVTCNT(9)
• NE_SEND_DATA(9)
• NE_RECV_DATA(9)

🍓 the MMIO buffer sizes

• Device MMIO buffer sizes(9)
• NE_SEND_DATA_SIZE(9)
• NE_RECV_DATA_SIZE(9)

✨ the MSI-X interrupt vectors

• MSI-X interrupt vectors(9)
• NE_VEC_REPLY(9)
• NE_VEC_EVENT(9)

💅 the structs and the function (the actual payload players)

• enum ne_pci_dev_cmd_type(9)
• struct enclave_start_req(9)
• struct enclave_get_slot_req(9)
• struct enclave_stop_req(9)
• struct slot_alloc_req(9)
• struct slot_free_req(9)
• struct slot_add_mem_req(9)
• struct slot_add_vcpu_req(9)
• struct slot_count_req(9)
• struct next_slot_req(9)
• struct slot_info_req(9)
• struct slot_add_bulk_vcpus_req(9)
• struct ne_pci_dev_cmd_reply(9)
• struct ne_pci_dev(9)
• ne_do_request(9)

🌈 that's the list, and yes, you're gonna want to read basically all of them — each one is a different little envelope for a request or a reply, and this page is just the girl standing at the door telling you who's who. no cap, go click through them.

and that's the whole page, bestie — short, sweet, absolutely serving as a directory and nothing more. 💜

sign-off time 🎀 this one lives under ./drivers/virt/nitro_enclaves, it's stamped October 2026, and the footer still calls itself Device comm...and replies.(9) — truncated title and all, and we love her for it. periodt. 💅✨
