💅 parport_ip32_read_control 💅

okay so bestie, welcome to a section 9 kernel API page from the Kernel API Manual, all about parport_ip32_read_control — yes that's a mouthful, yes you're gonna say it in your head three times before it sticks, and yes it's iconic 🎀

✨ NAME ✨

parport_ip32_read_control — returns the cached contents of the DCR register 💾✨

like, it doesn't go poke the hardware fresh, it hands you what's already been remembered. lowkey efficient, honestly.

🌸 SYNOPSIS 🌸

unsigned char parport_ip32_read_control (struct parport *p );

one function, one argument, returns an unsigned char, periodt 💅

🦋 ARGUMENTS 🦋

  • p — pointer to struct parport. that's it, that's the whole argument list. your friendly neighborhood parport pointer 🫶

⭐ DESCRIPTION ⭐

okay so here's the tea 🍵 — the return value is masked, so it only hands you back the values of these four bad boys:

  • DCR_STROBE
  • DCR_AUTOFD
  • DCR_nINIT
  • DCR_SELECT

the way that it filters out everything else… selective queen behavior, we love to see it 👑 anything outside those four bits? not invited to the function's return party 🙈

🔥 SEE ALSO 🔥

buckle up bestie, this list is long — like a group chat that just keeps adding people 😭 but every single one of them matters, no cap:

first up, the source file itself:

  • Kernel file ./drivers/parport/parport_ip32.c struct

then the whole friend group 💜:

iykyk 💫 that's the whole parport_ip32 cinematic universe and this function is absolutely a main character in it.

and that's the page, bestie!! 🫶 this lil beauty lives in ./drivers/parport and it's dated October 2026 — so go forth, read your cached DCR register contents, and slay 💖✨🌸
