versions using ioctl is not possible to insert to the kernel

[vysocky]

We have two system using the same CentOS 7 with old kernel (3.10.0-1160.80.1.el7.x86_64). One of the systems works perfectly with the master version of the amd_hsmp, however the other one (2x7763 + 8x A100 per node) fails when inserting the kernel module. It results in the following error:

insmod: ERROR: could not insert module amd_hsmp/4276242/amd_hsmp.ko: No such device

I have tested older versions of the code, and found out that only the very old version without ioctl interface (5d590b2) is possible to insert, and works fine.

Do you have a clue why the ioctl versions do not work? Thanks

Can you tell us the Fam/Model number of the system where this driver does not work.

As mentioned in the initial text, it is a system powered by two 7763 CPUs with Nvidia GPUs. Let me know what additional information you need.

Hi Vysocky,
7763 should be Milan, did you check if HSMP interface is enabled in the BIOS. Note: BIOS config options vary among ODMs.
Can you share the dmesg logs around the error while inserting.
