📦 version 7.3.1, in nixpkgs unstable

💅 omap4_cminst...isable_hwsup(9) — from the Kernel API Manual, bestie 🎀

okay so real talk, this one lives in the Kernel API Manual and the name got chopped for the header which is honestly iconic of it. let's get into it ✨

🌸 NAME 🌸

omap4_cminst_clkdm_disable_hwsup — the function that puts a clockdomain into swsup-idle mode. yes girl, we're turning off the hardware's autopilot and handing the wheel to software 🫶

✨ SYNOPSIS ✨

void omap4_cminst_clkdm_disable_hwsup (u8 part , u16 inst , u16 cdoffs );

three little args, zero return value, one very specific job. no cap 💅

🦋 ARGUMENTS 🦋

  • part — the PRCM partition ID, aka the neighborhood where this clockdomain's registers actually live 🏠
  • inst — the CM instance register offset, and it's literally the *_INST macro, iykyk
  • cdoffs — the Clockdomain register offset, that's the *_CDOFFS macro, don't forget the asterisk bestie ⭐

💖 DESCRIPTION 💖

so what this does is: it takes the clockdomain that (part, inst, cdoffs) points at and drops it into software-supervised idle mode. which lowkey means the Linux OMAP clockdomain code is the one controlling it manually now — hardware supervision? not invited. it's giving "I'll take it from here" energy 👑

and no, there's no return value. it just does the thing. periodt 💀

🔥 SEE ALSO 🔥

the source file is ./arch/arm/mach-omap2/cminst44xx.c and the whole friend group is here, go say hi 🫶

ngl if you need the opposite of this function, omap4_cminst_clkdm_enable_hwsup(9) is literally right there in the list, matching energy 🌈

🧚 cute little sign-off 🧚

that's the whole page! brought to you from ./arch/arm/mach-omap2, dated October 2026, and no I will not be taking questions about how a manual page from the future got in your terminal 💜✨ bye bestie, slay your clockdomains responsibly 🎀
