tools/virtio: stub might_sleep and synchronize_rcu

2025-12-24T13:02:56+00:00

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.

tools/virtio: add dev_WARN_ONCE and is_vmalloc_addr stubs

2025-12-24T13:02:56+00:00

Add dev_WARN_ONCE and is_vmalloc_addr stubs needed by virtio_ring.c. is_vmalloc_addr stub always returns false - that's fine since it's merely a sanity check. Created using Cursor CLI.

tools/virtio: fix build caused by virtio_ring changes

2023-04-21T07:02:35+00:00

Fix the build dependency for virtio_test. The virtio_ring that is used from the test requires container_of_const(). Change to use container_of.h kernel header directly and adapt related codes.

tools/virtio: fix the vringh test for virtio ring changes

2023-01-27T11:18:41+00:00

Fix the build caused by missing kmsan_handle_dma() and is_power_of_2() that are used in drivers/virtio/virtio_ring.c. Signed-off-by: Shunsuke Mie Message-Id: <20230110034310.779744-1-mie@igel.co.jp> Signed-off-by: Michael S. Tsirkin

tools/virtio: fix build

2022-08-11T08:26:07+00:00

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.

tools/virtio: add krealloc_array

2020-12-18T21:14:30+00:00

krealloc_array is used in drivers/vhost/vringh.c, add it to avoid build failure. Drop WARN_ON_ONCE, because duplicated with the one in bug.h Signed-off-by: Peng Fan Link: https://lore.kernel.org/r/20201209084205.24062-3-peng.fan@oss.nxp.com Signed-off-by: Michael S. Tsirkin

compiler: Remove uninitialized_var() macro

2020-07-16T19:35:31+00:00

Using uninitialized_var() is dangerous as it papers over real bugs[1] (or can in the future), and suppresses unrelated compiler warnings (e.g. "unused variable"). If the compiler thinks it is uninitialized, either simply initialize the variable or make compiler changes. As recommended[2] by[3] Linus[4], remove the macro. With the recent change to disable -Wmaybe-uninitialized in v5.7 in commit 78a5255ffb6a ("Stop the ad-hoc games with -Wno-maybe-initialized"), this is likely the best time to make this treewide change.

tools/virtio: Use tools/include/list.h instead of stubs

It should not make any significant difference but reduce stub code. Signed-off-by: Eugenio Pérez Link: https://lore.kernel.org/r/20200418102217.32327-9-eperezma@redhat.com Signed-off-by: Michael S. Tsirkin
