> There have been plenty of reports opened wrt libudev/libgcc_s/libstdc++ on their trackers and seemingly limited interest to fix things. Yes, there are a bunch of issues reported for this already. But it looks like Valve has no plan to fix these issues. For example, https://github.com/ValveSoftware/steam-runtime/issues/13 IMHO, we can probably use sysfs first, and when the issue is solved by Valve, we can switch to the udev solution later.

But we ran into some problems with these options for example when run Steam games which ships 32bit libraries (including libudev) in the steam runtime, so finally we decided to use sysfs directly to avoid introducing some additional dependencies into libdrm. >>> >>> The reason sounds wrong.

This is a catch 20/20 afaics. "FOSS drivers do not work thus they are s**t" is how a sizeable hunk of people think. They rarely consider what the actual issue might be, because "I installed the nvidia/amd proprietary drivers and things work now". > Anyway, this was just my two cents and you can obviously decide in any > way you deem to be the best. > Personally, I'd love if there was no "options" and we can just use libfoo. Who knows Valve devs might get a wake up call and fix the problem ? -Emil P.S. Fun fact: Valve's annual "TI" Dota2 tournament managed to accumulate some 66 million USD gross income, over 100 days. _______________________________________________ dri-devel mailing list dri-devel@xxxxxxxxxxxxxxxxxxxxx http://lists.freedesktop.org/mailman/listinfo/dri-devel
