I don't have any more protection than any other driver that accesses SOC registers directly. Last I heard, Zhang's DMA driver was in limbo, and that driver would be the best place to arbitrate DMA register access. I was planning on adding arbitration support to that driver after both drivers were applied. As for the GUTS driver, well, I just program a few registers at startup, and I don't think any other driver touches them. -- Timur Tabi Linux kernel developer at Freescale _______________________________________________ Alsa-devel mailing list Alsa-devel@xxxxxxxxxxxxxxxx http://mailman.alsa-project.org/mailman/listinfo/alsa-devel
