tools/virtio: remove smp_read_barrier_depends()

2022-12-28T10:28:11+00:00

This gets rid of the last references to smp_read_barrier_depends()
 which for the kernel side was removed in v5.9. The serialization
required for Alpha is done inside READ_ONCE() instead of having
users deal with it. Simply use a full barrier, the architecture
does not have rmb in the first place.

tools/virtio: initialize spinlocks in vring_test.c

2022-12-28T10:09:47+00:00

The virtio_device vqs_list spinlocks must be initialized before use to
prevent functions that manipulate the device virtualqueues, such as
vring_new_virtqueue(), from blocking indefinitely.

virtio_ring: split: stop __vring_new_virtqueue as export symbol

2022-08-11T08:06:38+00:00

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.

tools/virtio: compile with -pthread

2022-03-28T20:52:59+00:00

When using pthreads, one has to compile and link with -lpthread,
otherwise e.g. glibc is not guaranteed to be reentrant.

This replaces -lpthread.
