💖 panthor_gpu_block_power_on — it's giving "wake up bestie" ✨

okay so this is a page from the Kernel API Manual (yes, the Kernel API Manual, we're in the big leagues now 🎀) and it's literally just about turning ON one specific block of the GPU. that's it. that's the whole vibe check. and honestly? iconic. 🔥

✨ NAME ✨

panthor_gpu_block_power_on — Power-on a specific block of the GPU 💅

like, one block. not all the blocks. a block. main character energy but make it targeted. 🫶

🌸 SYNOPSIS 🌸

int panthor_gpu_block_power_on (struct panthor_device *ptdev , const
char *blk_name , u32 pwron_reg , u32 pwrtrans_reg , u32 rdy_reg , u64
mask , u32 timeout_us );

returns an int. seven arguments. yes SEVEN, don't @ me, we'll go through them one by one bestie 🦋

💜 ARGUMENTS 💜

  • ptdev — the Device. the whole device. the moment. 🫶
  • blk_name — the Block name. so we can call the block by name like a real one.
  • pwron_reg — the Power-on register for this block. this is the one that does the thing.
  • pwrtrans_reg — the Power transition register for this block. the transition. the glow-up. 🔥
  • rdy_reg — the Power transition ready register. it tells you when the block is done transitioning, i.e. when it's ready to slay.
  • mask — the Sub-elements to power-on. an u64 bitmask, so you can pick exactly which little sub-elements come to the party 💅
  • timeout_us — Timeout in microseconds. because we are NOT waiting forever, no cap. 😭

⭐ RETURN ⭐

0 on success, a negative error code otherwise 💀

fr fr, check that return value. 0 = slay. negative = not slay. that's the whole vibe check right there.
