[RFC 0/3] Dynanmic SSEU

[Navik, Ankit P]

Hi Tvrtko,



Following are my observation with the patch on drm-tip.

1. Switching  of SSEU is happening in the idle case.

i.e. Terminal is opened to collect the dmesg log on Ubuntu with GUI

     I am attaching dmesg log for more details.



2. manhattan results and power consumption:

I am not seeing any power difference with and without
drm-tip:
Power (mW)

Perf (fps)

With DEU patch:
Power (mW)

Perf (fps)

14972.35

62.71

14975.11

58.67

14975.22

62.67

14972.52

58.68


*Power numbers are collected using socwatach.



Regards,
Ankit
