hl_ack_pb_single_dcore(9)

📦 version 7.3.1, in nixpkgs unstable

💅 hl_ack_pb_single_dcore 💅

okay so bestie, welcome to the Kernel API Manual ✨ we're in the kernel-adjacent part of the manual-page world today, and this function is a whole vibe. Let's get into it 🫶

✨ NAME ✨

hl_ack_pb_single_dcore — ack pb for single docre in HW according to given configuration 💖

(yes that's the actual name and the actual job description, no cap — it acks the pb for a single dcore in the hardware, all according to whatever configuration you hand it 🌸)

🌈 SYNOPSIS 🌈

void hl_ack_pb_single_dcore (struct hl_device *hdev , u32 dcore_offset ,
u32 num_instances , u32 instance_offset , const u32 pb_blocks[] , u32
blocks_array_size );

it returns void, so like... it's giving "I do the work, I don't do the receipts" 💀 no return value to check, she just goes. 👑

🎀 ARGUMENTS 🎀

  • hdev — pointer to hl_device structure. this is the device handle bestie, the main character of the whole operation 🦋
  • dcore_offset — offset from dcore0. that's where we start counting from, the origin story fr fr ✨
  • num_instances — number of instances to apply configuration to. how many times we're doing the thing 💅
  • instance_offset — offset between instances. the lil gap between each one, iykyk 🌸
  • pb_blocks — blocks array. literally the array of blocks, she's right there 🎀
  • blocks_array_size — blocks array size. the size of that array, we love a matching pair 😭

the kernel file lives at ./drivers/accel/habanalabs/common/security.c — go read her, she's iconic 📖✨

and the whole friend group, in order, because we don't leave anyone out 🫶:

ngl, this is kernel-adjacent hardware security territory, so like... read the siblings before you start poking the pb blocks, bestie. safety first, slay second 💀💖
