A Look At Nouveau Driver Power Usage
Phoronix: A Look At Nouveau Driver Power Usage
There's been many individuals asking how the work is going in tracking down the major Linux kernel power regression I brought to light late last month (actually, there's at least two power regressions in the kernel). Not much progress has been made since then as I've been out of the office (and country) so I've been preoccupied with other matters, but I do happen to have another power test today to satisfy other reader requests.
What was this benchmark about?
Since noveau does not have power management enabled it was clear from the beginning it will perform similar to the blob with power management disabled. I was expecting a test with power management enabled (if noveau has this implemented, otherwise maybe for radeon that does have at least a basic implementation).
