Drivers

Thanks to rapido, it’s become much simpler to test Linux device drivers for real PCIe devices in VMs.

The advantages of this approach are:

• the host is protected from memory corruption errors caused by buggy kernel drivers

• the development cycle is short and simple - rapid even :)

I’ll be speaking at linux.conf.au 2018 in Sydney. Jittertrap testing infrastructure is slowly improving. The idea is to include known test data so that the front-end rendering can be verified and refactored. I expect a sprint over the holidays and some new bugs for lca. :) Clean up of the tn40xx dri…
