hl_fw_dynami...t_descriptor(9) β from the Kernel API Manual β¨
okay so bestie, welcome to the group chat π this one's short and sweet β it's literally just the handshake with the CPU to get the FW descriptor. yes, that handshake. no cap.
πΈ NAME πΈ
hl_fw_dynamic_request_descriptor β handshake with CPU to get FW descriptor π«Ά
β¨ SYNOPSIS β¨
int hl_fw_dynamic_request_descriptor (struct hl_device *hdev , struct
fw_load_mgr *fw_loader , size_t next_image_size );
that's the whole vibe, three args, she's giving "small function, big responsibility" π
π ARGUMENTS π
hdevβ pointer to thehabanalabsdevice structure π¦ this is the main character, the device herselffw_loaderβ the managing structure for loading the device's FW, lowkey the handler that keeps everything togethernext_image_sizeβ the size to allocate for the next FW component π this is how much room the next piece gets
π DESCRIPTION π
it returns 0 on success, otherwise a non-zero error code. that's it, that's the whole description fr fr π
so like β 0 means slay, anything else means something went sideways. check your error code, bestie, don't just assume π
π SEE ALSO π
okay the friend group here is huge, brace yourself π
