# viafb clock/PLL patches - List: linux-fbdev - 5 messages, 1 author - Page: https://ratatoskr.run/linux-fbdev/2011/03/3689148/t ## viafb clock/PLL patches - From: Florian Tobias Schandinat \ - Date: 2011-03-12 21:31:11 - Message: https://ratatoskr.run/linux-fbdev/2011/03/3689148.md ```text This patch series contains major changes in the way clocks are managed. A lot of duplicated and inaccurate values were removed and the behaviour for clocks without an exact match was improved. This causes some calculation overhead on each mode change but should allow easier extension and have always a behaviour that is at least as good as the old one but is much saner for some clocks. This will allow - easier adding of modes - using generic mode tables - easier adding of PLL configs - generate PLL values on-the-fly - use different clock sources Best regards, Florian Tobias Schandinat ``` ## \[PATCH 1/4\] viafb: remove duplicated clock information - From: Florian Tobias Schandinat \ - Date: 2011-03-12 21:31:32 - Message: https://ratatoskr.run/linux-fbdev/2011/03/3689150.md ```text This patch removes the direct lookup table for resolution+refresh and pixclock by calculating this information from the mode table. Removes a lot of dupllication and error potential by just doing a little more calculations on each mode change.

This allows easy adding of other known good pll values. Additionally it made it possible to remove invalid configurations resulting in better behaviour for such cases. The resulting clocks are no longer stored resulting in some computing overhead on each mode change.

From: Florian Tobias Schandinat \ - Date: 2011-03-12 21:31:41 - Message: https://ratatoskr.run/linux-fbdev/2011/03/3689152.md ```text Before this patch only clocks that perfectly match were used and if none existed this was not handled properly. This patch changes this to always use the closest clock supported. This should behave like before for clocks that have a perfect match but be much saner for clocks which are slightly off.
