I need demodulated data in my board emulation. The aim of my project is to emulate a PCI board which does not exist at this time, to help working on the driver.

I'm looking for realistic behaviour, performances is not a priority Jérôme _______________________________________________ Qemu-devel mailing list Qemu-devel@nongnu.org http://lists.nongnu.org/mailman/listinfo/qemu-devel
