I have patches to remove them, so feel free to ignore this problem for now. Sure, this is just getting the basic infrastructure in place. I'm ignoring e.g. the RECT pointers that aren't necessarily valid after the present call finishes as well, until the actual multi-threaded implementation comes along.

Afaics the main implication will be that functions that are called through the CS shouldn't place any commands into the stream. Depending on the synchronization between writer and reader this may work, but waiting for the CS to finish inside the command stream will never work right. -BEGIN PGP SIGNATURE- Version: GnuPG v2.0.20 (GNU/Linux) Comment: Using GnuPG with Thunderbird - http://www.enigmail.net/ iQIcBAEBAgAGBQJSRYblAAoJEN0/YqbEcdMw7IoQAJLgxf8nlDl+wGcdBlZlFhF1 nAL67t31vRSVONK/gjffW5P8V7dwNGw39gwh5sFt08Bsj0by4KAkhQ0N7Rnb6peL 7WzQdqhGWGlg+9RVUgZJeNo1LcWlglWxskfU+33wBbo6yMI3NGoKS+xF0wE1s5dS UHeuXr/2aJU9rYzcJCXTjtm294kO6r1ortk0n4+ucdg+oK7RB63sVHZaYmP3757m IDNs26+3YQFGxN49JFRZSAnbc9591QVM5sNp5UUnQkKP2GyV0r4qRO+ZJkAhnRKk hF59lCkf7+t038/LjcHB2PEvgmmL6rODc6hAPS1T9OsfomGfCnNZcKDe+X8SEpVC keKWO5OMc1h12D0DUQN9jjIaGOw7r2/zrYv8lWwU6sodFMInxhZaECGaF4edkmmb kUGuqyFp8I4+OErQbkGPgh5U9srK6866TX6dBzCaLDAxwskk5m2J1Y/ZC2EYS+Eo Lf88dLDohNg6LARyrIWDO+4ujUtbeCmCe+/UQ5bVPr1K4/3n2/HJY7Ekq1qkpdpr t7FY5KsqXuC9b38M4UN3SOlGv1juM8n1LYb7rHETYuXqFxrOFHXqapiomrqNBSZt CaA6OqDfWgq4f4YsAdvuA5J8ihn0TtMKFKV9y1krCowHk15bE8puYbZ37zYQlNDP mlSk+X5yt03k+WK1T+xu =6HrB -END PGP SIGNATURE-

Yeah, the main things I can think of is that you shouldn't generally generate CS ops from inside the CS, and you can't access device state. I'm not sure in how far those are going to be issues that require this kind of annotation though. The only things that should access device state are going to be the various device getters and stateblock capture, but those should only ever have external callers. The main cases for generating CS ops from inside the CS are probably blits, and perhaps resource maps. The basic rule should probably be that anything that makes wined3d_cs_emit_*() calls should only have callers outside of wined3d, which shouldn't be too hard to verify.
