Interesting - Nvidia RTX Ada 4000 RmInitAdapter failed when installed in a pci switch

Hi,

I’m developing a pre-Si PCie Switch in emulation environment (FPGA) with a dedicated board that serves as a PCIe bridge connected to the emulator with RTL of the switch.
the GPU is Nvidia RTX 4000 Ada. the emulator is connected to a Supermicro X11DAi-N.
Nvidia Driver version is 550.107.02 on Fedora 37 system.
When the host boots, dmesg shows several issues with the GPU initialization process like: RmInitAdapter: Cannot initialize GSP firmware RM.
when the GPU is connected directly to the host - it works fine!
I’ve attached the dmesg , lspci dump of the GPU and the Nvidia debug log.
I think that maybe because the GPU is slow because its connected an emulator so there are issues with timeout…
Please help me figure this out!

This is the Jetosn forum which is not able to support your RTX 4000 Ada issue.
Sorry for that.
