Hi all, Thanks to Christoph's latest series, I'm reminded that, if we're going to give the ARM DMA ops some cleanup this cycle, it's as good a time as any to dust off these old patches and add them on top as well. I've based these on the arm-dma-direct branch which I assume matches the patches posted at [1].All these do look sensible to me. But weren't you working on replacing the ARM iommu dma_ops with dma-іommu anyway?
Yes, that's somewhat entangled with the IOMMU bus ops stuff, so I'll probably get to the point of having to revisit it in a couple of months or so. These patches are off the bottom of that stack from my first attempt, where the aim was to make the current ops the same shape first so that the switch is then easier to reason about (particularly in terms of sounding out any issues with the hooking up of dev->dma_coherent, although your series will now be taking most of the load off there). Cheers, Robin. _______________________________________________ linux-arm-kernel mailing list linux-arm-kernel@lists.infradead.org http://lists.infradead.org/mailman/listinfo/linux-arm-kernel
