psb_spank(9)

💅 psb_spank(9) — like, the Kernel API Manual one, bestie 🎀

okay so picture this: you're deep in the kernel, the graphics engine is being A Whole Thing, and you just need it to soft reset and chill. that's literally this function's entire job. main character energy only ✨

🌸 NAME 🌸

psb_spank — reset the 2D engine 💫

not me reading "spank" and giggling. anyway. it resets the 2D engine. periodt.

---

✨ SYNOPSIS ✨

void psb_spank (struct drm_psb_private *dev_priv );

like, that's the whole signature. no return value (it's void, she gives nothing back and we respect that 🫶). copy it exactly, spaces and all — do not "fix" the space before that closing paren, iykyk 💅

---

🦋 ARGUMENTS 🦋

• dev_priv — our PSB DRM device 💖 like, our device. the one we're working with. it's a struct drm_psb_private * and it's the only thing you gotta hand over. she's lowkey the main character here ngl 👑

---

🔥 DESCRIPTION 🔥

soft reset the graphics engine, then reload the necessary registers. 💫

that's it. that's the vibe. soft reset — not a full dramatic meltdown reset, just a gentle "bestie, breathe, we're reloading the registers" moment 🧚✨

no cap, the registers do need reloading after. don't skip that part or it's giving chaos 😭

🌈 SEE ALSO 🌈

• Kernel file ./drivers/gpu/drm/gma500/psb_drv.c 👀 — go read it, fr fr, that's where the lore lives 📖

and that's the whole page, bestie!! short and iconic, just like her 💜 literally the entire manual in one function. slay.
