panic_nand_wait(9)

📦 version 7.3.1, in nixpkgs unstable

okay so bestie, we are deep in the Kernel API Manual today — that's the manual, yes, the whole vibe — and section 9's main character is panic_nand_wait(9). she's not famous but she's important okay 💅

🎀 NAME

panic_nand_wait — [GENERIC] wait until the command is done ✨

that's it. that's the whole pitch. wait until the command is done. lowkey iconic in its simplicity 🦋

🌸 SYNOPSIS

void panic_nand_wait (struct nand_chip *chip , unsigned long timeo );

not me copying the spacing exactly because we do not mess with the source 🫶

💖 ARGUMENTS

  • chip — the NAND chip structure 💫 like, the actual chip we're talking about here.
  • timeo — the timeout ⏳ your girl needs to know how long to wait before she gives up.

🔥 DESCRIPTION

okay so here's the tea: this function waits for command done. periodt.

she's a helper function for nand_wait — a little support system, a hype squad of one 🫶 — and she specifically gets called when we are in interrupt context. which, ngl, is already a spicy situation.

and when does that happen? may happen when in panic and we're trying to write an oops through mtdoops. so like, the kernel is literally having a whole crisis 😭 and we're still trying to get the oops out through mtdoops. main character energy in the middle of an emergency, honestly 💀

no cap, this is the "everything is on fire but the NAND write still needs to finish" function. respect her fr fr 🎀

like I said. a lot. but we read all of them, because that's what besties do 💜
