Open-Source Support For AMD "Richland" APUs

[madbiologist]

So who here has a Trinity APU based laptop and does suspend/hibernate work for you? My Asus N56DP never comes back from suspend successfully, the display never turns on. (But the system is awake, you can ssh into it, etc.)

I'm wondering if any of this new Richland support will also make Trinity behave better.

The 3.10 kernel contains a couple of Radeon suspend/resume fixes which might help.

Also make sure you have the latest BIOS update available at http://www.asus.com/Notebooks_Ultrab...pport_Download
One of the BIOS updates listed there mentions "Fix S4 Resume fail".

I think you need to mess with some package, I think its called radeon-tool or something. This tool can powerup the display and must be configured to be called. I forgot how its done, but I had *same*? problem with Xi 1554 - and that solved it.

Thanks for the suggestion. I just checked, and I've already got BIOS 214, which is the latest on the download site.

OK, I'll search for this, thanks for the hint.
