Hi, here's the qemu patch that implements the new adapter indicators ccw in virtio-ccw and injects adapter interrupts for the devices enabled for it. Cornelia Huck (1): s390/virtio-ccw: Adapter interrupt support. hw/s390x/css.c | 10 ++++++++ hw/s390x/css.h | 2 ++ hw/s390x/virtio-ccw.c | 66 ++++++++++++++++++++++++++++++++++++++++++++++++- hw/s390x/virtio-ccw.h |

Hi, here's the current implementation of virtio-ccw adapter interrupts in qemu. Code is unchanged, only rebased against current master.

Hi all, this series replaced the DMA_ATTR_NON_CONSISTENT flag to dma_alloc_attrs with a separate new dma_alloc_pages API, which is available on all platforms. In addition to cleaning up the convoluted code path, this ensures that other drivers that have asked for better support for non-coherent DMA to pages with incurring bounce buffering over can finally be properly supported.
