dpu_encoder_...periph_flush(9)

💅 dpu_encoder_needs_periph_flush — bestie edition

okay so real talk, you're looking at the kernel API page for dpu_encoder_needs_periph_flush, living under the dpu_encoder_...periph_flush(9) manual name in the Kernel API Manual. she's a little function with one job and she does it, periodt ✨

---

🌸 NAME 🌸

dpu_encoder_needs_periph_flush — returns true if the physical encoder requires a peripheral flush 💅

like, that's it. that's the whole vibe check. true or false, no in-between, no maybe.

---

✨ SYNOPSIS ✨

bool dpu_encoder_needs_periph_flush (struct dpu_encoder_phys *phys_enc
);

she takes one thing, she gives you back a bool. iconic behavior honestly 🎀

---

🦋 ARGUMENTS 🦋

• phys_enc — pointer to the physical encoder structure. yeah. that one. hand her the pointer and she'll tell you what's up 🫶

ngl there is exactly one argument here and it's this one. no hidden extras, no surprise guests.
