🦋 ixgbe_dbg_netdev_ops_read(9) — the kernel API manual page, bestie edition 🦋

Okay so picture this: you're deep in the ixgbe debugfs situation, section 9 of the Kernel API Manual, and you meet this little function. Her whole name is ixgbe_dbg_netdev_ops_read, and honestly? She's the read side of the netdev_ops debugfs datum. That's it, that's her whole job description. Slay.

✨ NAME ✨

ixgbe_dbg_netdev_ops_read — read for netdev_ops datum 💅

Like, literally the read handler. For the netdev_ops datum. No cap.

🌸 SYNOPSIS 🌸

ssize_t ixgbe_dbg_netdev_ops_read (struct file *filp , char __user
*buffer , size_t count , loff_t *ppos );

Look at her go. ssize_t return type, four arguments, main character energy fr fr. 🫶

🎀 ARGUMENTS 🎀

Bestie, let's do a vibe check on each one:

  • filp — the opened file. Yeah. The file that's open. That's the one. 🙈
  • buffer — where to write the data for the user to read. (Yes, write-for-reading, it's giving kernel-space chaos and we respect it. 😭)
  • count — the size of the user's buffer. Don't overflow it, that's not the move. 💀
  • ppos — file position offset. The little "where are we" bookmark. 🎀

🌈 SEE ALSO 🌈

And her whole friend group, the iconic ixgbe debugfs lineup:

All of them, together, one big debugfs family reunion. 🔥👑

Lowkey a note: the source path in the footer gets cut off as ./drivers/net/ethernet/intel/i... — that's just how it got rendered, not me being lazy, I promise 🫶

Okay that's the page!! Dated October 2026, pulled from the Kernel API Manual, source path ./drivers/net/ethernet/intel/i... ✨ Stay hydrated, go read some debugfs, mwah 💖🧚‍♀️
