📦 version 7.3.1, in nixpkgs unstable

💖 hl_init_pb_single_dcore — a kernel API manual moment 💖

okay so bestie, we're in the <pink>Kernel API Manual</pink> and today's main character is hl_init_pb_single_dcore(9). yes it's a mouthful. no you may not shorten it. she earned that name ✨

🌸 NAME 🌸

hl_init_pb_single_dcore — sets the pb for a single dcore in HW, according to the given configuration. that's it, that's the vibe 🎀

✨ SYNOPSIS ✨

int hl_init_pb_single_dcore (struct hl_device *hdev , u32 dcore_offset ,
u32 num_instances , u32 instance_offset , const u32 pb_blocks[] , u32
blocks_array_size , const u32 *user_regs_array , u32
user_regs_array_size );

she's an int, she takes eight things, and honestly? she ate 💅

🦋 ARGUMENTS 🦋

  • hdev — pointer to the hl_device structure. your main character struct fr fr 🫶
  • dcore_offset — the offset from the dcore0, iykyk 💜
  • num_instances — how many instances you want the config applied to. count 'em bestie 🔥
  • instance_offset — the offset between instances ⭐
  • pb_blocks — the blocks array 🎀
  • blocks_array_size — the blocks array size. yes, it's the size of the blocks array. we love a self-explanatory queen 👑
  • user_regs_array — the unsecured register array 🙈
