PCIem is a tool that allows you to create virtual hardware. This hardware is then seen by the kernel as one more PCI device. The idea of the tool is to be able to test drivers without having to use the actual hardware. It handles the typical characteristics of a PCIe device such as BARs, interrupts and DMAs among others.

Wine 11 available

With Wine 11, the API that allows you to run Windows programs on Linux is one step away from no longer needing 32-bit libraries to function since with the new WoW64 mode, it is possible to run 16 and 32-bit programs using only 64-bit libraries.
