[Barrelfish-users] Barrelfish networking and the rtl8029 driver

[Georgios Varisteas]

Hi,

My name is Georgios Varisteas and I recently started work on Barrelfish as a PhD student at KTH. I have been trying to set up Barrelfish in a virtual machine with networking enabled but I have run into various troubles. I am using barrelfish-20100810 snapshot. All three virtualization options available to me (Qemu, Vmware and Virtualbox) emulate a single network chipset for which there is a driver included in my snapshot and that is rtl8029. However, trying to build the driver has resulted in compilation errors which I do not really know how I should treat. After going through the source of the driver I've come to the conclusion that it is incomplete as there are data types being used that are not defined anywhere else in Barrelfish; I've relied on grep to verify this though. I include the GCC output at the end. Is it possible to somehow acquire the full version of the driver? What about the emulated e1000 chipsets: 82540EM, 82543GC and 82545EM? How easy would it be to extend the e1000n driver to support them? Finally, it would really help to know what to expect to see as output when a supported adapter is found by the PCI module and how addressing works inside Barrelfish.

regards,
Georgios
