RFE - debuginfo access - linux - via debuginfod protocol

Please consider adding debuginfod protocol client support to the debuginfo consumer tools such as vtune. An increasing number of linux distros/isvs are posting their debugging data in this format, and it's useful in workgroups too.

Hi,

Thanks for the suggestion.

We would like to know the kind of usecase in which you are trying to include this feature.

Also how would you like to include this in vtune?Can you elaborate on this?

In any DWARF consuming situation where the debuginfo data is not already found on your workstation, this facility allows the tool to quickly query online systems to download the specific bits, without need for privileged operations.

Whereever vtune-analyzer needs to find DWARF data - or source code - but fails, and if $DEBUGINFOD_URLS is set, it can make the HTTP webapi requests to fetch the content by hex buildid. The elfutils package has a client-side C library to automate this part, and includes a command line equivalent.
