MSR access

[Ferdi]

Dear all,

is it possible to get access to the MSR registers for the devcloud?

I would like to measure some intercore latencies on Skylake-SP

Best regards

Hi,

Thanks for reaching out.

Regarding MSR access in devcloud we will check with the admin team and let you know.

Hi,

Note that DevCloud policy does not allow root access to users.

As shown below user processes are allowed to read the first 64 Bytes of each PCI devices configuration space, but root permission is needed to read past that point.

$ lspci | grep :1e.3
16:1e.3 System peripheral: Intel Corporation Sky Lake-E PCU Registers (rev 04)

$ setpci -s 16:1e.3 0x9c.l
ffffffff

Thanks.
