> Subject: [dpdk-dev] [PATCH v3 2/2] eal: handle compressed firmwares
> 
> Introduce an internal firmware loading helper to remove code duplication
> in our drivers and handle xz compressed firmwares by calling libarchive.
> 
> This helper tries to look for .xz suffixes so that drivers are not aware
> the firmwares have been compressed.
> 
> libarchive is set as an optional dependency: without libarchive, a
> runtime warning is emitted so that users know there is a compressed
> firmware.
> 
> Windows implementation is left as an empty stub.

> Changes since v2:
> - added a comment on libarchive link dependency,
> 
> Changes since v1:
> - used pkg-config for libarchive detection,
> - updated doxygen annotations,
> - added internal helpers in eal_firmware.c to enhance readability,
> - dropped whitespace damage in version.map,
