[Qemu-devel] Kernel requirement for membarriers feature

Hi, When the membarriers feature was introduced, the kernel requirement was set to 4.14, however if my understanding of what is needed is correct that is rather strict? http://lists.gnu.org/archive/html/qemu-devel/2018-03/msg02748.html As far as i can tell the feature was introduced in 4.3 see:

[Qemu-devel] qemu-multi-configs.diff

Hi there There should exist a patch to get more than one usb device in Qemu, but all the links I can find are broken :( Could you guys help with that? Best regards Kim Højgaard-Hansen
