6 daystools/virtio: add device, device_driver stubsMichael S. Tsirkin

6 daystools/virtio: fix up oot buildMichael S. Tsirkin
oot build tends to help uncover bugs so it's worth keeping around, as long as it's low effort. add stubs for a couple of macros virtio gained recently, and disable vdpa in the test build.

6 daystools/virtio: switch to kernel's virtio_config.hMichael S. Tsirkin
Drops stubs in virtio_config.h, use the kernel's version instead - we are now activly developing it, so the stub became too hard to maintain.

6 daystools/virtio: stub might_sleep and synchronize_rcuMichael S. Tsirkin
Add might_sleep() and synchronize_rcu() stubs needed by virtio_config.h. might_sleep() is a no-op, synchronize_rcu doesn't work but we don't need it to. Created using Cursor CLI.

2025-09-12kmsan: convert kmsan_handle_dma to use physical addressesLeon Romanovsky
Convert the KMSAN DMA handling function from page-based to physical address-based interface. The refactoring renames kmsan_handle_dma() parameters from accepting (struct page *page, size_t offset, size_t size) to (phys_addr_t phys, size_t size). The existing semantics where callers are expected to provide only kmap memory is continued here.

2023-06-09tools/virtio: use canonical ftrace pathRoss Zwisler
The canonical location for the tracefs filesystem is at /sys/kernel/tracing. But, from Documentation/trace/ftrace.rst: Before 4.1, all ftrace tracing control files were within the debugfs file system, which is typically located at /sys/kernel/debug/tracing. For backward compatibility, when mounting the debugfs file system, the tracefs file system will be automatically mounted at: /sys/kernel/debug/tracing A few spots in tools/virtio still refer to this older debugfs path, so let's update them to avoid confusion.

2022-08-11virtio_ring: split: stop __vring_new_virtqueue as export symbolXuan Zhuo
There is currently only one place to reference __vring_new_virtqueue() directly from the outside of virtio core. And here vring_new_virtqueue() can be used instead. Subsequent patches will modify __vring_new_virtqueue, so stop it as an export symbol for now.

2022-03-06tools/virtio: fix virtio_test executionStefano Garzarella
virtio_test hangs on __vring_new_virtqueue() because `vqs_list_lock` is not initialized. Let's initialize it in vdev_info_init().
