✨ ahci_platform_assert_rsts(9) ✨

okay so bestie, welcome to the Kernel API Manual entry for ahci_platform_assert_rsts — yes the name is a mouthful, yes it's iconic, no we are not skipping any of it 💅

🌸 NAME 🌸

ahci_platform_assert_rsts — assert/rearm platform resets

like literally it asserts resets. or rearms them. both. it's giving multitasking queen 👑

🎀 SYNOPSIS 🎀

int ahci_platform_assert_rsts (struct ahci_host_priv *hpriv );

that's the whole vibe. one function, one argument, returns an int. short and slay ✨

🦋 ARGUMENTS 🦋

  • hpriv — the host private area where config values get stored. she's the storage unit, the little home for all your settings 🏠💖

💜 DESCRIPTION 💜

so what does she actually do? ahci_platform_assert_rsts asserts — or, for self-deasserting resets, rearms — all the reset controls it can find for the AHCI device. all of them. not some. not a few. all. periodt 🔥

ngl the "self-deasserting" part is the key detail here: some resets handle their own deassert, so for those this function rearms them instead. iykyk 🧚

⭐ RETURN ⭐

  • 0 if it went off without a hitch — success, we love to see it 🫶
  • otherwise, a negative error code — so like, if it's not zero, something went sideways, and it's negative. clock that 😭
