💅 pdcs_fastsize_read(9) — like, the Kernel API Manual, but make it cute

okay so bestie, welcome to pdcs_fastsize_read, straight out of the Kernel API Manual ✨ this one is a read function and it's giving "quiet little register reporter" energy and honestly? iconic.

✨ NAME ✨

pdcs_fastsize_read — Stable Storage FastSize register output. that's it, that's the whole vibe 🎀

🌸 SYNOPSIS 🌸

ssize_t pdcs_fastsize_read (struct kobject *kobj , struct kobj_attribute
*attr , char *buf );

literally just that. three args, one ssize_t return, no cap 💅

🦋 ARGUMENTS 🦋

  • kobj — the kobject that's used to share data with userspace. think of it as the little go-between that carries messages between kernel-land and the userspace girlies 🫶
  • attr — the kobject attributes. the ~metadata~ bestie, the whole personality of the thing ✨
  • buf — the output buffer you write to. this is where the tea gets poured 🍓

💜 DESCRIPTION 💜

so this register holds the amount of system RAM to be tested during the boot sequence. that's the whole thing! the FastSize register is basically the bouncer at the club going "okay how much RAM are we testing tonight" 🌈 and this function is the one handing that info back out. main character energy, honestly 👑
