Can I get CXL read information with pcm-sensor-server?

[hyeongtakji]

Hello,

d2a8e58 added CXL metrics, but as far as I can see, I can only check CXL write information with pcm-sensor-server. Is there any specific reason why CXL read has not been added?

there are some HW limitations of the PMU. But we can add system-wide CXL read metric in pcm-sensor-server (similar to the one in the pcm-memory).

Hello Dementiev, thank you for your reply.

Great to hear that! Is there any plan for support?

Hi Roman,
Can you advise whether the CXL read metrics limitation is addressed with Emerald Rapids?
Thanks, Dave

Hi Dave, (sorry for the late response) Emerald Rapids has the same limitation.
