📦 version 7.3.1, in nixpkgs unstable

💖 hisi_qm_sriov_enable 💖

okay so bestie, welcome to the Kernel API Manual — yes, that's the actual manual name, we're being official today 💅 — and this one little page is all about one function that does Exactly One Thing.

✨ NAME ✨

hisi_qm_sriov_enable — enable virtual functions 🦋

✨ SYNOPSIS ✨

int hisi_qm_sriov_enable (struct pci_dev *pdev , int max_vfs );

look at her. two arguments, one int coming back at you. she's simple, she's focused, she's the moment. 🎀

✨ ARGUMENTS ✨

  • pdev — the PCIe device 👑 like, the actual hardware bestie we're doing the thing to.
  • max_vfs — the number of virtual functions to enable 🔢 that's how many VFs you're asking for, bestie, so choose wisely.

✨ DESCRIPTION ✨

okay so the tea ☕ — this function returns the number of enabled VFs. that's the whole win. that's the slay.

but listen, there are two situations where it does NOT do that and instead returns failure 😭:

  • if there are VFs enabled already (like, girl, they're already on, we can't re-enable what's enabled 🙈), or
  • if max_vfs is more than the total number of VFs the device can enable (you're asking for more than the device can give, and no amount of manifesting is fixing that 💀).
lowkey important: those are the only two failure conditions on the page, so don't go inventing more, iykyk.
