pvr_build_firmware_filename(9)

💖 NAME 💖

okay bestie, welcome to the pvr_build_firmware_filename(9) page from the Kernel API Manual ✨ this one is literally about constructing a PowerVR firmware filename, and it's giving "small helper, big filename energy" 🎀

📜 SYNOPSIS 📜

char * pvr_build_firmware_filename (struct pvr_device *pvr_dev , const
       char *base , u8 major );

🧩 ARGUMENTS 🧩

• pvr_dev — target PowerVR device 🎯
• base — first part of the filename 🧵
• major — major version number 🔢

🌸 DESCRIPTION 🌸

okay so a PowerVR firmware filename is made of three parts separated by underscores ('_'), plus a .fw file suffix. no cap 🦋

1. the first part is the exact value of base — like, whatever string you passed in, that's what goes there 💅
2. the second part is the hardware version string derived from pvr_fw 🛠️
3. the final part is the firmware version number constructed from major with a 'v' prefix 🔥

so for example, it can come out looking like powervr/rogue_4.40.2.51_v1.fw — iconic format, honestly ✨

bestie, the returned string will have been slab allocated and must be freed with kfree. do not forget, or it's leak vibes 😭💀

🎀 RETURN 🎀

• the constructed filename on success ✅
• any error returned by kasprintf 😭
