LCE-EU 2015

Testing software against obscure inputs to find bugs is very important. The same thing can be done for certain hardware drivers, where the "input" is the driven device itself. In this talk, Marek will first explain how to attach an FPGA to a board and model hardware in the FPGA. Afterward, he will explain how to use this model for fuzz testing of a driver. This approach is useful in particular for testing storage bus drivers -- SD controller drivers, SPI bus drivers, NAND controller drivers. Such testing method is not specific to Linux, but can be used for testing drivers elsewhere as well, for example in U-Boot bootloader or RTOSes.

At the end of the talk, there will be a short demo of an emulated SD card plugged into a Linux system.
