Hi, I'm working with the arago omapl1 kernel on a custom OMAP-L138 board.
http://arago-project.org/git/projects/?p=linux-omapl1.git Recently I made some testing with the PREEMPT_RT patches (that were also applied in a branch in the arago kernel). The Kernel seems to behave correctly but I have issues with the GPIO interface. E.G. I'm using the "gpio-keys" and "matrix-keypad" drivers and they don't behave correctly. The symptoms are : Just after boot, I can press a button attached to a GPIO and get an event through the input subsystem, but after a few presses (few being random) the button doesn't generate an event any-more. (the interrupt is also not reported in /proc/interrupts). By browsing the mailing list archives I saw these old patches for the davinci tree and the omap tree : http://linux.omap.com/pipermail/davinci-linux-open-source/2007-October/004283.html http://marc.info/?l=linux-omap&m=119634477133936&w=2 (both are also listed here https://rt.wiki.kernel.org/index.php/CONFIG_PREEMPT_RT_Patch) Of course quite a lot of things changed since 2.6.23 so it's difficult to just adapt the patches (I don't even know if they are still required or if I'm facing another issue). Anyway just wanted to know if someone is having the same issues or if there is a new version of the patches for the latest davinci kernel that I may have missed.
