pruss_cfg_update(9)

okay so bestie, this is pruss_cfg_update(9) from the Kernel API Manual, and it's literally here to configure a PRUSS CFG sub-module register with main-character energy 👑✨

🌸 NAME 🌸

pruss_cfg_update — configure a PRUSS CFG sub-module register. That's the whole vibe: it configures one register in the PRUSS CFG sub-module, periodt 💅

✨ SYNOPSIS ✨

int pruss_cfg_update (struct pruss *pruss , unsigned int reg , unsigned
int mask , unsigned int val );

🫶 ARGUMENTS 🫶

• pruss — the pruss instance handle. Your handle to the pruss instance, iykyk 🦋
• reg — register offset within the CFG sub-module. It tells you where the register lives 💖
• mask — bit mask to use for programming the val. The mask that goes with the write, no cap 🎀
• val — value to write. The actual value going in, slay ✨

💅 DESCRIPTION 💅

It programs a given register within the PRUSS CFG sub-module. That's it, that's the function — you bring the pruss, reg, mask, and val, and it programs that given register inside the PRUSS CFG sub-module, slay 🔥✨

🎀 RETURN 🎀

Returns 0 on success, or an error code otherwise 😭. So 0 is the happy path, and anything else is the "bestie something went sideways" path 💀
