__e1000_write_phy_reg_hv(9)

πŸ“¦ version 7.3.1, in nixpkgs unstable

✨ __e1000_write_phy_reg_hv β€” the Kernel API Manual entry you didn't know you needed ✨

Okay bestie, sit down, grab a strawberry drink πŸ“, because we're diving into a Kernel API Manual page for a lil function called __e1000_write_phy_reg_hv. Yes it has two underscores, no we're not renaming it, that's its whole thing πŸ’…


🌸 NAME 🌸

__e1000_write_phy_reg_hv β€” literally just writes an HV PHY register. That's it, that's the job 🫢


πŸ¦‹ SYNOPSIS πŸ¦‹

s32 __e1000_write_phy_reg_hv (struct e1000_hw *hw , u32 offset , u16
data , bool locked , bool page_set );

Look at her. Five whole parameters. Main character signature energy fr fr πŸ‘‘


πŸŽ€ ARGUMENTS πŸŽ€

  • hw β€” pointer to the HW structure. The hardware bestie we're working with πŸ’–
  • offset β€” the register offset you're writing to. Where the data's gonna live ✨
  • data β€” the actual data being written at that register offset. The content itself, the substance, the moment πŸ“
  • locked β€” tells you whether the semaphore has already been acquired or not. Like, is the door already open or do we need to knock? πŸšͺ
  • page_set β€” BM_WUC_PAGE is already set and access is enabled. Already prepped, already slay 🌈

πŸ’œ DESCRIPTION πŸ’œ

So here's the vibe: it acquires the semaphore if necessary, then writes the data to the PHY register at the offset. And then β€” super important β€” it releases any acquired semaphores before exiting. No semaphore left behind, no leaked locks, we are responsible in this household 😀✨

That's genuinely the whole description. Short. Efficient. It's giving minimalism πŸŽ€


πŸ”₯ SEE ALSO πŸ”₯

Okay this is the long part, and yes we're doing all of them, don't @ me πŸ’€ First up, the source file itself:

Kernel file ./drivers/net/ethernet/intel/e1000e/phy.c

And now the full friendship circle 🫢:

That's seventy-something cross references and we listed every single one because that's what she deserves πŸ‘‘βœ¨


πŸ’€ Real talk though: this page is from ./drivers/net/ethernet/intel/e... (the path got cut off in the footer, rip 😭), dated October 2026, and it lives under the Kernel API Manual name. So when you cite it, cite it right, iykyk 🧚

Stay hydrated, release your semaphores, and remember: acquire if necessary, release before exiting. Periodt πŸ’…πŸ¦‹πŸŒΈ
