Sorry about that. Do you mind if I add a note about it, or > alternatively will you be ok with pushing your tool to libdrm ?

So i do not want to commit to do such thing. But i definitly use the bof feature, last time was a month or so ago to debug something. It have been very usefull to me in the past and i expect for as long as the radeon ddx stays releavant it will be in the future. But with the advance of the modesetting ddx and glamor, the tracing that does exist in mesa will be as easy as the bof tracing. If not easier. So i am not sure of the value there is into putting effort into this. This kind of feature is really usefull when debugging lockup, at least this allow me to bisect offend command stream to pin point the last dword before lockup and thus get a clue about what kind of cmd is the root cause. Dunno how others dev do such thing. > I'm not sure that your suggestion will work - one cannot exclude bof.h > (and bof.c) from the distribution as it's used by radeon_cs_gem.c. > Annotating the symbols as hidden/private should work for everyone. How > does that sound ? I do not see how this is an issue, symbol needed by radeon_cs_gem can be hidden from other and thus there is no point into shipping bof.h Really no symbol need to be exported, iirc i tend to ln -s the bof files in my tools or simply cp the lastest version from libdrm into a local copy but i still need bof.h to have all symbol listed.
