Configure BIOS

[Congyu Liu]

Hi,

(I previously sent this request in another thread but it may have been missed, so I am re-sending here.)

Experiment: https://www.cloudlab.us/status.php?uuid=d1a06068-b415-11f0-bc80-e4434b2381fc

I'd like to request the following BIOS configuration changes on n0 (node 0):

Could you please:

• Enable TME-MK (Multi-Key Total Memory Encryption),

• Enable TME Encryption Bypass for KeyID 0,

• Ensure that TME-MK Integrity Mode and Intel TDX are disabled,

• Disable Node Interleaving

• Enable Sub NUMA Cluster

Thank you so much!

Best,

Congyu

This is done.

Hi Administrators,

Sorry to reach out again — could you help me disable the TME Encryption Bypass setting on node 0 (n0)?

Feel free to reboot the machine at any convenient time to apply the change. 

Thanks again for your help!

Best,

Actually, ignore my previous message...

The issue is that Intel TDX is still enabled. Could you help me disable the TDX (and keep everything else the s

Thanks!

Following up on my previous request about TDX, I can only see one NUMA node, but there should be 2 or 4 with Sub NUMA Clustering enabled...

When you get a chance, could you please help me check that the following three settings are active in the BIOS?
* TDX: disabled
* Node Interleaving: disabled
* Sub NUMA Clustering: enabled

Thank you!

Best,
Congyu

Hi Cloudlab Administrators,

Just wanted to follow up on this request. Please let me know if you need any additional information or assistance.

Also, would it be possible for you configure this on a new experiment instead? That way, I can reserve it for a longer period. If that works better, I’ll create a new experiment and send over the full instructions.

Thanks so much for your help,

Congyu

I disabled TDX and enabled sub numa clustering. I did not see an option
for node interleaving.
