💅 ixgbe_acquire_swfw_sync — a Kernel API Manual moment

okay so bestie, we're in the Kernel API Manual today and this page is literally about grabbing a semaphore. not the vibe-y "semaphore" you're thinking of, it's the SWFW one. let's go 🫶

🌸 NAME 🌸

ixgbe_acquire_swfw_sync — acquire the SWFW semaphore. that's it, that's the whole name. iconic minimalism.

✨ SYNOPSIS ✨

int ixgbe_acquire_swfw_sync (struct ixgbe_hw *hw , u32 mask );

it returns an int, it takes two things, and yes the spacing is a little quirky. we respect the spacing. 💅

🎀 ARGUMENTS 🎀

  • hw — pointer to the hardware structure. your main character struct fr fr, the one that knows where all the registers live 🌈
  • mask — the mask that specifies which semaphore you're trying to acquire. pick your fighter 🔥

🦋 DESCRIPTION 🦋

so what does it actually do? it acquires the SWFW semaphore through the GSSR register, and it does it for the specified function. and the functions on the menu are, in the original's exact words: CSR, PHY0, PHY1, EEPROM, Flash. five little guys, one register, one semaphore, no cap 💖

that's the whole description, and honestly? she said what she said. short, sweet, does the job ✨

👑 SEE ALSO 👑

bestie buckle up, this list is enormous and every single one of these is coming with us. no skipping, no summarising, we ride at dawn 🧚

first up, the source file itself:

  • Kernel file ./drivers/net/ethernet/intel/ixgbe/ixgbe_common.c

and now the whole extended family 😭:

like I said. enormous. she has a big family and she loves them all 💜

real talk for a sec: the original page gives us no error codes, no return values beyond the int in the synopsis, no environment variables, no files beyond the one source path, and no warnings. so we're not inventing any. we just vibe with what's there ✨ no cap.

and that's the page, bestie! this one came from ./drivers/net/ethernet/intel/i... — yes the path got a little truncated in the footer, she's mysterious like that 💅 — and the footer dates it October 2026 under the title ixgbe_acquire_swfw_sync(9). go forth and acquire your semaphores, periodt 🦋🎀
