hl_unsecure_register_range(9)

🎀 NAME 🎀

okay so bestie, welcome to hl_unsecure_register_range(9) from the Kernel API Manual 💖. the whole vibe is: locate the relevant block for this register range and remove corresponding protection bit. that's it, no cap — very "find the block, yeet the protection bit" energy ✨.

✨ SYNOPSIS ✨

the signature is literally:

int hl_unsecure_register_range (struct hl_device *hdev , struct range
mm_reg_range , int offset , const u32 pb_blocks[] , struct
hl_block_glbl_sec sgs_array[] , int array_size );

💅 ARGUMENTS 💅

• hdev — pointer to hl_device structure 🫶
• mm_reg_range — register address range to unsecure 💅
• offset — additional offset to the register address ✨
• pb_blocks — blocks array 🎀
• sgs_array — pb array 🦋
• array_size — blocks array size 🌸
