tools/virtio: fix build breakage

2017-05-02T20:41:43+00:00

Previous commit ("virtio: add context flag to find vqs") added a new 'context' flag to vring_new_virtqueue(), but the corresponding API in tools/virtio/ is not updated causing build errors due to conflicting declarations. Bring code in tools/virtio in sync with that in kernel. I have used 'false' for the value of the new boolean 'context' flag as that seems to be the best way to preserve existing behavior. Tested with: $ make -C tools/virtio clean all ARCH=x86 Signed-off-by: Sekhar Nori Signed-off-by: Michael S. Tsirkin

tools/virtio: use {READ,WRITE}_ONCE() in uaccess.h

2016-12-15T22:13:37+00:00

As a step towards killing off ACCESS_ONCE, use {READ,WRITE}_ONCE() for the virtio tools uaccess primitives, pulling these in from . With this done, we can kill off the now-unused ACCESS_ONCE() definition. Signed-off-by: Mark Rutland Cc: Jason Wang Cc: Michael S.

tools/virtio: fix READ_ONCE()

2016-12-15T22:13:36+00:00

The virtio tools implementation of READ_ONCE() has a single parameter called 'var', but erroneously refers to 'val' for its cast, and thus won't work unless there's a variable of the correct type that happens to be called 'var'. Fix this with s/var/val/, making READ_ONCE() work as expected regardless. Fixes: a7c490333df3cff5 ("tools/virtio: use virt_xxx barriers") Signed-off-by: Mark Rutland Cc: Jason Wang Cc: Michael S.

tools/virtio: add dma stubs

Fixes build after recent IOMMU-related changes, mustly by adding more stubs. Signed-off-by: Michael S. Tsirkin

virtio_ring: Support DMA APIs

2016-03-02T15:01:57+00:00

virtio_ring currently sends the device (usually a hypervisor) physical addresses of its I/O buffers. This is okay when DMA addresses and physical addresses are the same thing, but this isn't always the case. For example, this never works on Xen guests, and it is likely to fail if a physical "virtio" device ever ends up behind an IOMMU or swiotlb. The immediate use case for me is to enable virtio on Xen guests. For that to work, we need vring to support DMA address translation as well as a corresponding change to virtio_pci or to another driver. Signed-off-by: Andy Lutomirski Signed-off-by: Michael S.

tools/virtio: fix byteswap logic

2015-12-07T15:28:10+00:00

commit cf561f0d2eb74574ad9985a2feab134267a9d298 ("virtio: introduce virtio_is_little_endian() helper") changed byteswap logic to skip feature bit checks for LE platforms, but didn't update tools/virtio, so vring_bench started failing. Update the copy under tools/virtio/ (TODO: find a way to avoid this code duplication). Cc: Greg Kurz Signed-off-by: Michael S. Tsirkin
