✨ omap4_cminst_clkdm_enable_hwsup ✨

okay so bestie, we're in the Kernel API Manual today — pull up a chair, grab a lil snack 🍓, and let me tell you about omap4_cminst_clkdm_enable_hwsup(9) because this one is literally so simple it's almost iconic for it.

💖 NAME 💖

omap4_cminst_clkdm_enable_hwsup — put a clockdomain in hwsup-idle mode

like. that's it. that's the whole vibe. hwsup-idle mode ✨

🎀 SYNOPSIS 🎀

void omap4_cminst_clkdm_enable_hwsup (u8 part , u16 inst , u16 cdoffs );

note the void bestie — this one is not coming back with an answer. it just does its thing 💅

🌸 ARGUMENTS 🌸

three lil guys walk into a clockdomain, and they are:

  • part — the PRCM partition ID where the clockdomain registers live. like, which neighbourhood we're in 🏡
  • inst — the CM instance register offset (that's the *_INST macro, iykyk)
  • cdoffs — the Clockdomain register offset (and that's the *_CDOFFS macro, no cap)

🦋 DESCRIPTION 🦋

ok so what does it actually do?? it takes the clockdomain that you pointed at with (part, inst, cdoffs) and puts it into hardware-supervised idle mode. that's the whole storyline. no plot twist, no return value. 🫶

the way that it's lowkey just three arguments and a dream 😭

mwah 💋 that's the page! it came from ./arch/arm/mach-omap2 and it's dated October 2026 — so basically a time traveller 🧚 stay hydrated, keep your clockdomains supervised, and I'll see you in the next manpage bestie 💖✨🎀
