💅 PVR_CR_FIELD_GET(9)

okay so bestie, this is a page from the Kernel API Manual and it's about one tiny little macro that does one tiny little job, and honestly? she ate. ✨

---

🌸 NAME 🌸

PVR_CR_FIELD_GET — literally extracts a single field from a PowerVR control register 🎀

---

🦋 SYNOPSIS 🦋

PVR_CR_FIELD_GET (val , field );

---

✨ ARGUMENTS ✨

• val — the value of the target register. like, the actual number you're digging into 🫶
• field — the field specifier, as defined in "pvr_rogue_cr_defs.h". that's where all the field definitions live, iykyk 💅

---

👑 RETURN 👑

the extracted field. that's it. that's the whole vibe. 🌈
