💅 _setup_reset(9) — like, the whole vibe

okay so real talk: you're in the Kernel API Manual, section 9, and the star of the show today is _setup_reset. she resets an IP block during the setup process and honestly? she ate. let's get into it 🫶

✨ SYNOPSIS ✨

int _setup_reset (struct omap_hwmod *oh );

that's it. that's the whole signature. iconic behaviour, no notes. 💅

🎀 ARGUMENTS 🎀

  • oh — type struct omap_hwmod *. yes bestie, that's the whole description. she's a pointer to a hwmod struct, that's the moment, that's the assignment. 🦋

🌸 DESCRIPTION 🌸

okay so picture this: you've got an IP block, right? and you want it reset — but specifically during the setup process, not whenever you feel like it. _setup_reset is the girl for that job. she takes the hwmod oh, finds the IP block that corresponds to it, and resets it. periodt. 👑

and here's the lil detail that matters (iykyk): the IP block gets first enabled so that it can actually be successfully reset. you can't reset a block that's asleep, that's not a vibe, that's just chaos. so she wakes her up first, then does the reset. 💖

what does she give you back? returns 0 upon success, or a negative error code upon failure. so like — check your return values, bestie. no cap, 0 is the green flag, negative is the "we need to talk" text. 😭

🔥 SEE ALSO 🔥

so there's a lot here and I'm not skipping a single one, because every single one is part of the family. also heads up: the kernel file for all this is ./arch/arm/mach-omap2/omap_hwmod.c — that's the address, that's where the lore lives. 🧚

like I said. entire family. every single cousin showed up to the function call. 💀

ok that's the page bestie, go reset something responsibly 💜
