💖 _enable_wakeup — Kernel API Manual energy 💖

okay so bestie, we're in the <pink>Kernel API Manual</pink> today and I need you to lock in, because this one is short but it's doing exactly what it says on the tin. no lore, no mystery, just one bit that needs flipping. 🦋

✨ NAME ✨

_enable_wakeup — set the OCP_SYSCONFIG.ENAWAKEUP bit in the hardware. that's it. that's the whole personality. 💅

🌸 SYNOPSIS 🌸

int _enable_wakeup (struct omap_hwmod *oh , u32 *v );

🎀 ARGUMENTS 🎀

  • oh — a struct omap_hwmod *. this is the hardware module we're talking about, the main character of this function. 👑
  • v — the manpage literally just says -- undescribed -- and honestly? iconic of it. no description provided, bestie, the docs said "figure it out." 💀

🧚 DESCRIPTION 🧚

so what this does is it lets the hardware module oh send wakeups. that's the vibe. it returns -EINVAL if something goes wrong (error moment 😭) or 0 if it all worked out (slay ✨).

like, no cap, that's the entire description. some functions have paragraphs of behaviour and edge cases and this one is just "flip the bit, allow the wakeups, return 0 or -EINVAL." lowkey refreshing ngl. 🫶

💜 SEE ALSO 💜

the kernel file in question lives at ./arch/arm/mach-omap2/omap_hwmod.c — that's the home base, your girl's address, iykyk. 🏠

and now the full friend group, because apparently everyone in omap_hwmod knows each other and they ALL showed up to the function: 😭

and that's the whole page, bestie. go flip your ENAWAKEUP bit, you're gonna do great. 🫶✨

sign-off szn: this little number comes from ./arch/arm/mach-omap2, and it's dated October 2026 — mark your calendars, the future is now, periodt. 💅🎀
