virtio_ring: fix avail_wrap_counter in virtqueue_add_packed (2023-09-03 18:10:24 -0400)
----------------------------------------------------------------
virtio: features
a small pull request this time around, mostly because the
vduse network got postponed to next relase so we can be sure
we got the security store right.

Hi,
above patch (upstream commit 295525e29a5b) seems causing a virtnet
related Call Trace after WARNING from kernel/dma/debug.c.
details (log and test setup) tracked in
https://bugzilla.kernel.org/show_bug.cgi?id=218204
it's recently noticed in a TDX guest testing since v6.6.0 release cycle
and can still be reproduced in latest v6.7.0-rc3.
as local bisects results show, above WARNING and Call Trace is linked
with this patch, do you mind to take a look?
Looks like virtqueue_dma_sync_single_range_for_cpu() use
DMA_BIDIRECTIONAL unconditionally.
We should use dir here.
Mind to try?
Thanks
sure, but what I see in the code
virtqueue_dma_sync_single_range_for_cpu() is using DMA_FROM_DEVICE,
probably I misunderstood your point?
Please let me know any patch/setting to try here.
