hl_unsecure_register(9)

okay so bestie, welcome to hl_unsecure_register(9) from the Kernel API Manual 💅✨ this page is short but it still ate, and we are keeping every single detail. no cap.

bestie, it’s a kernel function page — no options, no defaults, no environment variables, just the signature, the arguments, and the see-also squad. we’re still gonna make it cute 🫶

💖 NAME 💖

hl_unsecure_register — locate the relevant block for this register and remove corresponding protection bit 🎀

✨ SYNOPSIS ✨

it’s giving “kernel function that returns int”, and the signature is exactly this, bestie:

int hl_unsecure_register (struct hl_device *hdev , u32 mm_reg_addr , int offset , const u32 pb_blocks[] , struct hl_block_glbl_sec sgs_array[] , int array_size );

🎀 ARGUMENTS 🎀

• hdev — pointer to hl_device structure. main-character device-pointer energy 👑
• mm_reg_addr — register address to unsecure. 💅
• offset — additional offset to the register address. ✨
• pb_blocks — blocks array.
• sgs_array — pb array.
• array_size — blocks array size. 🦋
