👑 PVR_HAS_ENHANCEMENT(9) — Kernel API Manual 👑

okay so bestie, welcome to the PVR_HAS_ENHANCEMENT(9) page from the Kernel API Manual — it's literally the vibe check for hardware enhancements, and we're gonna read it together 💅✨

✨ NAME ✨

PVR_HAS_ENHANCEMENT — Tests whether a physical device has a given enhancement 🎀

🌸 SYNOPSIS 🌸

PVR_HAS_ENHANCEMENT (pvr_dev , enhancement );

🦋 ARGUMENTS 🦋

• pvr_dev — [IN] Target PowerVR device. 🫶
• enhancement — [IN] Hardware enhancement name. ✨

💖 DESCRIPTION 💖

okay so here's the lore: enhancement numbers are derived from those found in #pvr_device_enhancements by dropping the 'has_ern' prefix, which is applied by this macro. That prefix situation is handled for you, bestie — iconic behavior, honestly 💅

🌈 Returns 🌈

• true if the enhancement is present in the hardware, or
• false if the enhancement is not present in the hardware. 😭
