There is a better solution, which is to use threaded interrupts where needed. But I must confess that I am disappointed that you still fail to see how the pca953x patch actually eliminates the need for serialization. But I don't think there is much point in going on about that. The phy driver should be rewritten to use a threaded handler, it will solve my particular problem. And in the meantime, I have been promised to get the phy interrupts ofloaded to real CPU interrupt lines :-) Oh, I still think that the disable_irq_nosync documentaiton is misleading. Functions that are allowed in a particular context should not call functions that are not allowed to be called in that context. But now I know :-) /Esben -- Esben Haabendal, Senior Software Consultant DoréDevelopment ApS, Ved Stranden 1, 9560 Hadsund, DK-Denmark Phone: +45 51 92 53 93, E-mail: e...@doredevelopment.dk WWW: http://www.doredevelopment.dk _______________________________________________ Linuxppc-dev mailing list Linuxppc-dev@lists.ozlabs.org https://lists.ozlabs.org/listinfo/linuxppc-dev
