https://bugzilla.kernel.org/show_bug.cgi?id=91861 --- Comment #13 from Mike S. <michael.selig@xxxxxxxxx> --- Wow, thank you very much for the detailed explanation :-) Though all I was really expecting was a "yes/no or not sure" answer to whether the new higher values of fb_dev & ref_div on my RS780 could be responsible for pushing the PLL "closer to the edge" than with the driver on kernel 3.14, and therefore maybe less stable and/or produce more heat. So, from your explanation, using a ref_div of 7 compared to 2, means that the VCO is running at a higher frequency, and hence, higher voltage. So I assume that would mean the GPU would be drawing more power & therefore run hotter, though I am not sure how significant this is to its overall power use. Is that right? The reason I would like to know this is to determine whether the new divider numbers would cause the GPU to be less stable & hotter, which is fairly important in a HTPC where I am trying to keep fan noise to a minimum. If so, I might then try to force the ref_div below 7 in the driver (as I know it has been stable for several years at 2). -- You are receiving this mail because: You are watching the assignee of the bug. _______________________________________________ dri-devel mailing list dri-devel@xxxxxxxxxxxxxxxxxxxxx http://lists.freedesktop.org/mailman/listinfo/dri-devel
