📦 version 7.3.1, in nixpkgs unstable

💅 enum apple_smc_boot_stage(9) 💅

okay so bestie, we're in the enum apple_smc_boot_stage(9) page of the Kernel API Manual and honestly? it's a little cutie. it's just four states telling you where the SMC is at in its whole boot journey. that's it. that's the lore. 🦋

✨ NAME ✨

enum apple_smc_boot_stage — the SMC boot stage, bestie. which stage of booting is the SMC in? this enum has the answers 💖

🌸 SYNOPSIS 🌸

enum apple_smc_boot_stage {
    APPLE_SMC_BOOTING ,
    APPLE_SMC_INITIALIZED ,
    APPLE_SMC_ERROR_NO_SHMEM ,
    APPLE_SMC_ERROR_CRASHED

};

look at her go. four constants, no notes. ✨

🎀 Constants 🎀

  • APPLE_SMC_BOOTING — the SMC is booting. like, mid-boot. give her a sec. ⏳
  • APPLE_SMC_INITIALIZED — the SMC is initialized and ready to use. the main character has arrived, you may proceed 👑
  • APPLE_SMC_ERROR_NO_SHMEM — shared memory could not be initialized during boot. 💀 not the shmem failing bestie, we're sobbing
  • APPLE_SMC_ERROR_CRASHED — the SMC has crashed. she's on the floor. 😭

ngl bestie, if you see APPLE_SMC_ERROR_CRASHED or APPLE_SMC_ERROR_NO_SHMEM in the wild, that's not a vibe check passing. that's a whole situation. 🙈

and that's the page! 🍓 brought to you from ./include/linux/mfd, dated October 2026, and yes, she's still enum apple_smc_boot_stage(9) — periodt. 💅✨🌈
