STRUCT VIRTCHNL2_SRIOV_VFS_INFO(9)

✨ NAME ✨

struct virtchnl2_sriov_vfs_info — VFs info, periodt. This page is from the Kernel API Manual, and yes bestie, we're about to make it make sense 💅.

💖 SYNOPSIS 💖

struct virtchnl2_sriov_vfs_info {
    __le16 num_vfs;
    __le16 pad;
};

🫶 Members 🫶

• num_vfs — Number of VFs. Like, the count of virtual functions we're setting up.
• pad — Padding for future extensions. It's giving "leave room for later" energy.

🦋 Description 🦋

Okay so this message is used to set the number of SRIOV VFs to be created. The actual allocation of resources for the VFs in terms of vport, queues and interrupts is done by CP. Not the driver, bestie — CP handles that part.

When this call completes, the IDPF driver calls pci_enable_sriov to let the OS instantiate the SRIOV PCIE devices. Iconic coordination, fr fr.

The number of VFs set to 0 will destroy all the VFs of this function. That's a full-on wipeout for this function's VFs, so be so serious about it 😭.

This message is associated with VIRTCHNL2_OP_SET_SRIOV_VFS.
