πŸ“¦ version 7.3.1, in nixpkgs unstable

πŸ’… igb_set_d0_lplu_state_82575 β€” from the Kernel API Manual ✨

okay so bestie, welcome to the group chat for igb_set_d0_lplu_state_82575(9). this is a kernel API manual page, it's giving very "deep in the driver, do not touch unless you know what you're doing" energy, and honestly? we're gonna get through it together 🫢


✨ NAME ✨

igb_set_d0_lplu_state_82575 β€” Set Low Power Linkup D0 state πŸŽ€


🌸 SYNOPSIS 🌸

s32 igb_set_d0_lplu_state_82575 (struct e1000_hw *hw , bool active );

like, that's the whole thing. two arguments. we love a low-argument function fr fr πŸ’–


πŸ¦‹ ARGUMENTS πŸ¦‹

  • hw β€” pointer to the HW structure. it's your whole hardware situation, the main character of the driver πŸ‘‘
  • active β€” true to enable LPLU, false to disable. yes queen, a boolean, we love clarity πŸ’…

πŸ”₯ DESCRIPTION πŸ”₯

so the way this works is β€” it sets the LPLU D0 state according to the active flag. that's the whole vibe check. when you're activating LPLU, this function also disables smart speed, and vice versa. so it's a package deal, no cap, they flip together πŸ™ˆβœ¨

but here's the catch bestie, and it's giving gatekeeping: LPLU will not be activated unless the device autonegotiation advertisement meets standards of either 10 or 10/100 or 10/100/1000 at all duplexes. like if the advertisement doesn't meet spec, it's just not happening, periodt.

also very important: this is a function pointer entry point only, called by PHY setup routines. so it's not a "hey let me just call this from my own code" situation, it's an internal gig. iykyk πŸ’œ
