2008/6/24 Jiri Palecek <jpalecek@web.de>:Last, would it be possible to make it also consider the maximum pixelclock ofthe CRT (for example, if you want the maximum pixelclock of the CRT, the algorithm might get a higher frequency)?The algorithm is limited by the range of clocks that the pll is able to produce. Presumably mode validation has culled out any modes that the monitor is not able to handle.
True, but I was thinking about cases where monitor can handle some (upper limit) frequency, but the pll cannot produce it, and can produce some higher frequency (which can be the best match).
PS: As I think about it once more, I think the line + max_ref_div = 2*max_ref_div - min_ref_div;is an error. I added it to ensure the algorithm wouldn't cut the range of ref_divs if they are all valid, but now I think it's unneeded and errorneous.
