Ok, ide-lib.c can call blk_queue_bounce_limit with only 3 different args:
1) BLK_BOUNCE_HIGH (--> blk_max_pfn) 2) BLK_BOUNCE_ANY (--> blk_max_lo_pfn) 3) pci_dev->dma_mask
David, you're not setting PCI_DMA_BUS_IS_PHYS properly. For IOMMU it should be set to zero. This tells the block layer if you're IOMMU or not.
I knew it would be a bug like this.
Anyways, the problem case is #3 above and that will never happen if you start setting PCI_DMA_BUS_IS_PHYS to zero as appropriate. - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
