I've been using my apitrace-based shader-db so far, but it's slow (apitrace decompression), intrusive (apitrace windows spamming the screen), and doesn't have much coverage. The original shader-db provides a lot more coverage and compiles faster, at the expense of not having the actual runtime variant key. As v3d has a lot less runtime variation than vc4 did, this tradeoff makes more sense.
