> Subject: [dpdk-dev] [PATCH v5] devtools: add tags and cscope index file
> generation support
> X-Mailer: git-send-email 2.5.5
>
> This script generates cscope, gtags, and tags index files based on
> EAL environment(architecture and OS(linux/bsd)).
>
> Selection of the architecture and OS environment is based on dpdk
> configuration target(T=).If EAL environment(T=) is not specified,
> the script generates tag files based on available source code.
>
> Usage: make tags|cscope|gtags|etags [T=config]
>
> example usage:
> make cscope
> make tags T=x86_64-native-linuxapp-gcc
> make gtags T=arm64-armv8a-linuxapp-gcc
