[Intel-gfx] 830GM still woes

Hi Daniel, hi folks, still a couple of observations from my side on this. The 1024x786x24 mode here uses a clock of 65MHz (65000kHz), if that is inserted into the watermark computation, it computes from that a prefetch of 40 entries, and thus a watermark level of four, which is much much too hi

Hi Daniel, dear list, just tried the latest nightly build of 3.15.0+, and I'm sorry to say that the watermark configuration of the 830GM is still off. This is what I get from the kernel: (not to be taken too serious, but humor is the only thing that keeps me from getting seriously anoyed afte
