Documentation request: AMD debug variables
The environment variable page on mesa3d.org[1] is a nice, centralized resource for debug variables and what they do, but there is no info for r600, radeonsi, or radv.
I found some incomplete attempts to document this at Padoka's PPA info page[2] and Gentoo's wiki[3], but they could have dated info.
Please consider adding a couple sections for these drivers to the mesa webpage.
