Hi Oded Gabbay and habanalabs folks.
I'm insterested in this kind of AI acceralator.
After scanning the driver code.
It seems that there are a linux firmware which is loaded by
coprocessor(an slave cpu ?).
shows in the code.
./goya/goya.c:74:#define GOYA_LINUX_FW_FILE "habanalabs/goya/goya-fit.itb"
./goya/goya.c:2436: return hl_fw_load_fw_to_device(hdev, GOYA_LINUX_FW_FILE, dst, 0, 0);
./goya/goya.c:2507: fw_loader->linux_img.image_name = GOYA_LINUX_FW_FILE;
./gaudi/gaudi.c:63:#define GAUDI_LINUX_FW_FILE "habanalabs/gaudi/gaudi-fit.itb"
./gaudi/gaudi.c:3945: return hl_fw_load_fw_to_device(hdev, GAUDI_LINUX_FW_FILE, dst, 0, 0);
./gaudi/gaudi.c:4011: fw_loader->linux_img.image_name = GAUDI_LINUX_FW_FILE;
And the host driver(/driver/misc/habanalabs) communicate with the slave firmware
by MMIO or share memory, right?
If that, would you mind provide the source code of linux firmware
to avoid the confusion from code reading.
BTW, where can I find the register description datasheet
Many Thanks,
Cai

Hi Cai,
You can download the source code from:
https://vault.habana.ai/artifactory/misc/hl-linux.bz2

We don't supply this information.
Thanks,
Oded

Thanks, that's what I need, pretty nice code!
And I will be glad to see you taking it into the linux mailine soon.
Thanks,
