[PATCH 00/14] tools/virtio: cleanups, fixes

From: Michael S. Tsirkin

Date: Thu Dec 04 2025 - 13:46:06 EST


Recent virtio changes brought about build errors for tools/virtio,
as usual. I did some refactoring to hopefully reduce maintainance
load going forward.

Adding stubs is tedious and seemed a perfect fit for cursor -
so I used it for that, then rewrote some commits and accepted
others. commit logs I've rewritten.

Found and fixed a couple of minor bugs while doing this - that
part's all mine.

Michael S. Tsirkin (14):
tools/virtio: fix up compiler.h stub
virtio: make it self-contained
tools/virtio: use kernel's virtio.h
tools/virtio: add struct module forward declaration
tools/virtio: stub DMA mapping functions
tools/virtio: add dev_WARN_ONCE and is_vmalloc_addr stubs
tools/virtio: add ucopysize.h stub
tools/virtio: pass KCFLAGS to module build
tools/virtio: add struct cpumask to cpumask.h
tools/virtio: stub might_sleep and synchronize_rcu
tools/virtio: switch to kernel's virtio_config.h
virtio_features: make it self-contained
tools/virtio: fix up oot build
tools/virtio: add device, device_driver stubs
