rpi_firmware_property(9)

💖 NAME 💖

okay so bestie, this is rpi_firmware_property(9) from the Kernel API Manual — the icon that submits a single firmware property. The name is literally:

rpi_firmware_property - Submit single firmware property

periodt, it’s giving exactly what it says 💅

✨ SYNOPSIS ✨

int rpi_firmware_property (struct rpi_firmware *fw , u32 tag , void
       *tag_data , size_t buf_size );

🎀 ARGUMENTS 🎀

• fw — pointer to firmware structure from rpi_firmware_get. like, the firmware handle you already grabbed, bestie.
• tag — one of enum_mbox_property_tag. pick your tag, no cap ✨
• tag_data — tag data buffer. this is where the tag’s data lives.
• buf_size — buffer size. yes, the size of the buffer, she said what she said 🫶

🦋 DESCRIPTION 🦋

so here’s the vibe: this function submits a single tag to the VPU firmware through the mailbox property interface. that’s the whole thing.

It’s a convenience wrapper around rpi_firmware_property_list to avoid some of the boilerplate in property calls. lowkey helpful, highkey iconic 💖
