[Qemu-devel] [PATCH 2/7] s390x/3270: fix instruction interception handler

[Christian Borntraeger]

From: Dong Jia Shi <address@hidden>

Commit bab482d7405f ("s390x/css: ccw translation infrastructure")
introduced instruction interception handler for different types of
subchannels. For emulated 3270 devices, we should assign the virtual
subchannel handler to them during device realization process, or 3270
will not work.
