[PATCH 0/1] MR3491: winegstreamer: Leave media source critical section before unlocking workqueue.
by Bernhard Kölbl (＠besentv) 02 Aug '23

02 Aug '23

Today, if media_source_Shutdown is called around the same time as a work item is put on the async_commands_queue, we end up in a deadlock if Shutdown enters media source's cs first, as it waits for the queue's callback to finish, which, in turn, waits for the object's cs to be released. To avoid this leave the cs, before unlocking the workqueue, to let any callback on the queue finish running.

[PATCH v3 0/2] MR2853: Draft: win32u: Implement EVENT_SYSTEM_FOREGROUND
by Esme Povirk (＠madewokherd) 02 Aug '23

02 Aug '23

I expect this is going to be tricky to get in. I ran into the following issues: * test_ShowWindow behaves very strangely on Windows. It seems this isn't typical behavior, and is caused by an interaction with test_SetFocus, but I'm not sure exactly what it does to the thread state that causes this. * Many of the SetWindowPos flag combinations tested don't actually show the window on Windows, therefore they don't send EVENT_SYSTEM_FOREGROUND. I was able to reproduce this with a stand-alone test, so it seems to be normal behavior. * Windows can show a window without activating it, and Wine on X11 can't do that reliably for managed windows. * There are a couple of cases where Windows sends an event and Wine doesn't. I figure it's OK to not cover every case, but I can go back and investigate those if needed. This interacts with https://gitlab.winehq.org/wine/wine/-/merge_requests/2314, in that the tests don't really test much without it. I applied that MR for my own testing. -- v3: win32u: Implement EVENT_SYSTEM_FOREGROUND. user32: Run tests that notice focus changes early. https://gitlab.winehq.org/wine/wine/-/merge_requests/2853

[PATCH 0/1] MR3485: msxml3/tests: Use wide strings to generate BSTRs in schema.c.
by Michael Stefaniuc (＠mstefani) 02 Aug '23

02 Aug '23

Gets rid of an a2bstr() like helper. _bstr_() helper is kept as it is used to simplify the clean up of the generated BSTRs. -- https://gitlab.winehq.org/wine/wine/-/merge_requests/3485

[PATCH v8 0/5] MR280: vkd3d-shader: sm1 semantic matching.
by Zebediah Figura (＠zfigura) 02 Aug '23

02 Aug '23

This is probably the most ugly and controversial bit of API. I don't really know if this is the right approach to solving this. sm4 registers match by register index, such that shaders can mostly be compiled in isolation. sm1 does not—registers may be specified in any order in the vertex and pixel shaders, and will be matched by usage and usage index. By itself this is not much of a problem. Where it gets hairy is that we want to do some degree of caching, as well as pre-compilation, and avoid recompiling either shader every time it's matched with a new one. Wine currently deals with this problem, for GLSL, by generating a "main" GLSL shader for the vertex shader, and then an extra function setup_vs_output(), and linking the two together every time a new pixel shader is used. This could in theory be used for SPIR-V, but it requires the use of extra, probably external, code to link SPIR-V shaders together, which I do not particularly anticipate being well-received. (I'm not sure how Wine deals with this problem in the ARB backend. It seems to take the pixel shader signature into account when generating the vertex shader— cf. init_output_registers()—but it doesn't take it into account when looking up a vertex shader variant? I didn't look too closely at the code, so maybe I'm missing something.) -- The vkd3d parts of this patch are quite straightforward, and looking at them, I think the design is quite intuitive in isolation. There may be some room for internal refactoring (in particular with an eye to not so much overloading the "register_index" field of struct shader_signature_element) but I'm relatively happy with the way it turned out. In isolation, that is. The Wine part is worse. I've uploaded branches for vkd3d and Wine that use this API, and correctly handle shaders with some nontrivial reordering: https://gitlab.winehq.org/zfigura/vkd3d/-/commits/himavant5 https://gitlab.winehq.org/zfigura/wine/-/commits/himavant_cb The test can be run, as before, like so: make tests/shader_runner.exe && WINE_D3D_CONFIG=renderer=vulkan wine tests/shader_runner.exe ../vkd3d/tests/hlsl/sm1-interstage-interface.shader_test The interesting Wine parts are concentrated in a single patch, 5cfb9d930f11e. The patch takes a few shortcuts, partly because I wanted not to block the vkd3d API design questions, but also because while writing it I came up with a couple of problems that I wasn't sure how to fix. There are two main problems I see: (1) This patch has the user pass the signature from the pixel shader when compiling the vertex shader, and looks up register indices already arbitrarily allocated by the pixel shader. This is problematic when trying to use this signature as a cache key, by virtue of it not being clear (or even defined) which fields are key elements and which aren't. It's also not particularly kind to lookup, on account of not being directly comparable with memcmp(). There are a few options I see: (a) Provide an internal function to compare key elements. This feels... odd, like a very special-purpose function, but perhaps workable. (b) Just make the user deal with it, and assert that all fields are key elements. (c) Use some alternative, perhaps shortened structure as a field of vkd3d_shader_next_stage_info. This has the disadvantage that it is not as simple for a hypothetical user to retrieve from the pixel shader, but we would presumably provide a function to generate one from a shader signature. This would probably also be kinder to cache lookup if it's shorter. (d) Make caching vkd3d's responsibility, to some degree. This seems daunting, but the more we optimize, the more difficult it may be to design API that allows for nice caching. (2) Assuming we use signatures, there is a memory management problem that 5cfb9d930f11e spells out. This is probably a matter of "just fix it", but I suppose another option is to take the GLSL or ARB architecture. -- April is the cruellest month, breeding Lilacs out of the dead land, mixing Memory and desire, stirring Dull roots with spring rain. -- v8: vkd3d-shader: Introduce a function to build a varying map between sm1 stages. vkd3d-shader/spirv: Make output varyings not consumed by the next stage private variables. vkd3d-shader: Implement remapping shader output registers to match the next shader's semantics. https://gitlab.winehq.org/wine/vkd3d/-/merge_requests/280

It's no problem to send fewer of these per MR. I have included the complete set because all but the last introduce no functional changes, and upstreaming a smaller set would leave the changes in a half-done state with unnecessary buffering. -- This merge request has too many patches to be relayed via email.
