[PATCH 0/2] net: Update MemReentrancyGuard for NIC

Posted by Akihiko Odaki 11 months, 2 weeks ago

Recently MemReentrancyGuard was added to DeviceState to record that the
device is engaging in I/O. The network device backend needs to update it
when delivering a packet to a device.

This implementation follows what bottom half does, but it does not add
a tracepoint for the case that the network device backend started
delivering a packet to a device which is already engaging in I/O. This
is because such reentrancy frequently happens for
qemu_flush_queued_packets() and is insignificant.

This series consists of two patches. The first patch makes a bulk change to
add a new parameter to qemu_new_nic() and does not contain behavioral changes.
The second patch actually implements MemReentrancyGuard update.
