https://bugzilla.kernel.org/show_bug.cgi?id=30922 --- Comment #4 from Denis Washington <denisw@xxxxxxxxx> 2011-05-27 09:30:10 --- I have talked to Dave Airlie on IRC (#radeon at freenode) today and it seems that my assumption that thermal sensor access is needed for proper fan control is wrong. Rather, the GPU seems to do fan control automatically and can only be influenced by the driver by giving a new policy table to the graphics card's BIOS. The radeon driver doesn't currently do this, however, and relies on the BIOS' defaults, which however seem to be bad on my machine. This is why my fan mostly runs in full speed. Dave says he thinks that there's some of the code lying around inside AMD to do proper fan control setup, but still in need of a lot of review. If this is the case, I would be happy to test the code once it's published in git. (Please correct me if I am wrong about anything I've written here.) -- Configure bugmail: https://bugzilla.kernel.org/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are watching the assignee of the bug. ------------------------------------------------------------------------------ vRanger cuts backup time in half-while increasing security.
