xe_gt_sriov_pf_assert_vfid(9)

✨ NAME ✨

xe_gt_sriov_pf_assert_vfid — okay so this one warns you if &id is not a supported VF number, but only when you're debugging 💅

🌸 SYNOPSIS 🌸

xe_gt_sriov_pf_assert_vfid (gt , vfid );

🎀 ARGUMENTS 🎀

• gt — the PF xe_gt you wanna assert on, bestie 🫶
• vfid — the VF number to assert, like, the actual number okurrr

💖 DESCRIPTION 💖

So what this does is assert that gt belongs to the Physical Function (PF) device, and that the vfid you handed it is within the range of supported VF numbers — up to the maximum number of VFs the driver can support, including VF0 which represents the PF itself ✨

It's giving "trust but verify" energy. Lowkey iconic 👑

🦋 NOTE 🦋

This is effective only on debug builds, no cap. See Xe Asserts_ for more information 🔥
