tools/virtio: initialize spinlocks in vring_test.c

2023-01-24T06:24:30+00:00

[ Upstream commit c262f75cb6bb5a63828e72ce3b8fe808e5029479 ] 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.

Fix the build caused by the following changes: - phys_addr_t is now defined in tools/include/linux/types.h - dev_warn_once() is used in drivers/virtio/virtio_ring.c - linux/uio.h included by vringh.h use INT_MAX defined in limits.h Signed-off-by: Stefano Garzarella Message-Id: <20220705072249.7867-1-sgarzare@redhat.com> Signed-off-by: Michael S.

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. Reported-by: Matthew Wilcox Signed-off-by: Michael S. Tsirkin
