Wine test week 2 - nice apparent progress
by Jeremy White 18 Apr '14

18 Apr '14

My script results are here: http://www.winehq.org/~jwhite/ebd5f96aea22.html We had a lot of tests that had failed on Windows 7 ultimate that we now skip; that has reduced the number of apparent failures on the new testbot machines down under 20. We've also had some nice work from folks like Dmitry (thanks!). I'll keep annotating the failures until they all have notes. I do have one that could use a sucker^H^H^H^H^H^Hvolunteer: http://test.winehq.org/data/ebd5f96aea22f4093d4ceb109bdead2657666c57/xp_new… I had asked Misha Koshelev (the apparent last person to meaningfully change those tests) if he wanted to look into it, but he's in the middle of a medical internship working brutal hours, so he demurred. Cheers, Jeremy

At some point wined3d_texture_get_sub_resource() will go away of course, but I don't think there's a reason we can't e.g. have a wined3d_resource_get_sub_resource_desc(), or alternatively just store the information on d3d9 volume creation.

Note that you can't expose these formats without also implementing "Fetch-4", since that's implied by DF24. See also http://developer.amd.com/wordpress/media/2012/10/Advanced-DX9-Capabilities-…. Does this patch help any application?

Hi, While running your changed tests on Windows, I think I found new failures. Being a bot and all I'm not very good at pattern recognition, so I might be wrong, but could you please double-check?

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 Fyi, doing the same for surfaces will take a while because a number of surface-related functions have to be moved out of the way first.
