hl_fw_dynamic_send_msg(9)
π hl_fw_dynamic_send_msg(9) β kernel API manual, bestie edition π
okay so literally welcome to the kernel API manual, this one's about hl_fw_dynamic_send_msg(9) and honestly? it slays in the most niche way possible. it's a habanalabs firmware thing, iykyk. let's get into it β¨
πΈ NAME πΈ
hl_fw_dynamic_send_msg β bestie, this is the one that sends a COMMS message with attached data. like it literally ships the message AND the data together, no cap π«Ά
β¨ SYNOPSIS β¨
int hl_fw_dynamic_send_msg (struct hl_device *hdev , struct fw_load_mgr
*fw_loader , u8 msg_type , void *data );
that's the whole signature, copy it exactly, do not freestyle it π
π¦ ARGUMENTS π¦
hdevβ pointer to the habanalabs device structure. it's giving "the device, the main character" πfw_loaderβ managing structure for loading device's FW. yes FW = firmware, she's in charge of the whole load-up vibe πmsg_typeβ message type. au8, so keep it smol πdataβ data to be sent. it's avoid *, she's flexible like that π
π DESCRIPTION π
return 0 on success, otherwise non-zero error code. that's it, that's the description, and honestly? iconic minimalism. zero = we ate, non-zero = we did not eat ππ₯
π₯ SEE ALSO π₯
the kernel file, right here, go look at her:
./drivers/accel/habanalabs/common/firmware_if.c

ngl these are all cross-references to other kernel API pages in section 9, so if a name looks like a whole sentence, that's just how kernel devs name things, we don't question it π
and that's the page!! tiny but mighty π this cutie lives in ./drivers/accel/habanalabs/common and the doc says October 2026, so write that down bestie. mwah, study hard, slay the kernel πΈπππ¦
