💅 hl_fw_dynamic_wait_for_status — Kernel API Manual ✨

okay so bestie, picture this: you're loading firmware onto a habanalabs device and you just gotta sit there and wait for the FW to report back that it's in the status you asked for. that's this function. she's the patient queen of the dynamic FW load world 👑

🌸 NAME 🌸

hl_fw_dynamic_wait_for_status — wait for status in dynamic FW load. literally what it says on the tin, no notes 💖

🎀 SYNOPSIS 🎀

int hl_fw_dynamic_wait_for_status (struct hl_device *hdev , struct
       fw_load_mgr *fw_loader , enum comms_sts expected_status , u32 timeout );

like, four whole arguments. she's got range ✨

🦋 ARGUMENTS 🦋

  • hdev — pointer to the habanalabs device structure. the main character, the device herself 💅
  • fw_loader — managing structure for loading device's FW. think of it as the little organizer tote bag for the whole firmware-loading situation 🎀
  • expected_status — expected status to wait for. this is the vibe we're holding out for, the one we want FW to hit 🎯
  • timeout — timeout for status wait. the clock is ticking bestie, we are not waiting forever ⏰

💜 DESCRIPTION 💜

returns 0 on success, otherwise a non-zero error code. periodt. 🙌

and like — the waiting for status from FW includes polling the FW status register until the expected_status is received or the timeout occurs (whichever occurs first, no cap, the universe decides 🌀). so she's just out here checking the register on loop like "are we there yet? are we there yet?" until either the answer is yes or the clock runs out 😭

fr fr though, whichever happens first wins — got a status? slay. timed out? non-zero error code, that's the whole deal 💀
