[Qemu-devel] QTest with TCG?

["Edgar E. Iglesias" <edgar.iglesias@gmail.com>]

Hi,

I would like to use qtest for testing hw-models in combination with firmware.

At the moment I'm using the following patch to allow qtest to run without
accel=qtest. I'm mostly interested in the mem access functions and the
interrupt interception. I guess time stepping wouldnt work without
accel=qtest, but maybe that could be an acceptable limitation.

Is there anything in principle with such a setup that would cause problems?

Thanks,
Edgar
