Is there an easy way to monitor how many PCI-E lanes are being used? That way once KMS and everything are in and we get more power saving options it'd be interesting to see how it scales (and verify that it's working).
Is there a command I can use to print the currently active number of lanes? Just kinda curious.
I think agd5f created a patch which would indicate power state (and pcie lane) changes in your xorg log. It's not standard code because it's not considered nice to write an infinite number of lines to the log under normal conditions
Cool, I'll check the gitweb if it's in there.
It won't be AFAIK, I think he posted it here. Check the original power management thread from a couple of months ago.
@bridgman and agd5f
When disabling the function call to change number of active pcie lanes, within the ForceLowPowerMode function in radeon_pm.c, everything works fine.
I can suspend, reboot, shutdown and there aren't any corruptions whatsoever.
Thats with ForceLowPowerMode enabled btw.
