pvr_meta_cr_read32(9) 🌈

okay bestie, welcome to the Kernel API Manual page for pvr_meta_cr_read32 — yes, the META-register-via-Slave-Port girlies are thriving today 💅. this is the function that does exactly what the NAME says, no cap.

✨ NAME ✨

pvr_meta_cr_read32 - Read a META register via the Slave Port. periodt 💖

💅 SYNOPSIS 💅

the signature is giving exactly this, so copy it character-for-character, bestie:

int pvr_meta_cr_read32 (struct pvr_device *pvr_dev , u32 reg_addr , u32
*reg_value_out );

🎀 ARGUMENTS 🎀

okay so here's the cast of this little function, fr fr:

• pvr_dev — Device pointer. main character energy, lowkey.
• reg_addr — Address of register to read. the “where we’re looking” of it all 👀.
• reg_value_out — Pointer to location to store register value. yes, it's a pointer-to-the-spot situation, iconic ✨.

🔥 RETURN 🔥

vibe check on the return value:

• 0 on success, or
• Any error returned by pvr_cr_poll_reg32.

so if it's not 0, bestie, that error is coming straight from pvr_cr_poll_reg32 — no extra lore added by me 🙈.
