GenWQE (Generic Work Queue Engine) is a PCIe acceleration card. This repository contains the source code to test, maintain and update the GenWQE PCIe card. Furthermore a zlib version with hardware acceleration is provided to do zlib style compression/decompression according to RFC1950, RFC1951 and RFC1952. This can be used as alternative to the traditional software zlib.

The GenWQE PCIe card can currently be aquired as an option to the latest IBM System p machines:
- EJ12 regular height: PCIe3 FPGA Accelerator Adapter (FC EJ12; CCIN 59AB)
- EJ13 low profile: PCIe3 LP FPGA Accelerator Adapter (FC EJ13; CCIN 59AB)
On modern IBM System p servers, the accelerator card can use the new
CAPI interface. Install the libcxl
library into the toplevel genwqe-user directory and build the library
via make before compiling the genwqe tools.
