💾 xe_gt_sriov_pf_config_save(9) — Kernel API Manual 💾

okay bestie, welcome to the Kernel API Manual page for xe_gt_sriov_pf_config_save(9). This one is giving “save the VF provisioning config as a binary blob” energy, and we’re gonna get through every arg, return value, and reference without losing a single crumb. no cap. ✨

✨ NAME ✨

xe_gt_sriov_pf_config_save — Save a VF provisioning config as binary blob.

Like, it’s the save button for a VF provisioning config, but make it raw bytes, bestie. 💅

🎀 SYNOPSIS 🎀

here’s the signature, character-for-character:

ssize_t xe_gt_sriov_pf_config_save (struct xe_gt *gt , unsigned int vfid
       , void *buf , size_t size );

💅 ARGUMENTS 💅

  • gt — the xe_gt. The GT object in question, front and center.
  • vfid — the VF identifier. can't be PF — the page is loud about that, so don’t try it. 🫶
  • buf — the buffer to save a config to, or NULL if you’re querying the buf size.
  • size — the size of the buffer, or 0 if you’re querying the buf size.

🦋 DESCRIPTION 🦋

This function can only be called on PF.

That’s the whole vibe check, bestie: PF only. If you’re not on PF, this function is not the move. periodt. 🦋

🔥 RETURN 🔥

It returns the minimum size of the buffer, or the number of bytes saved, or a negative error code on failure. So you’re either getting size info, actual saved bytes, or a lil negative error telling you it didn’t slay. 😭
