This is usually prefered above GetVersion(). I must say that I do see other GetVersion() calls in the kernel32 tests. The fact that you are using win_skip will make the tests fail if you run Wine in Win98 mode, but I guess nobody does that. -- Cheers, Paul.

I don't think we want to use any random mono dll we find, especially in a way where we can't predict which one will be used. -- Alexandre Julliard julliard(a)winehq.org

Re: About the Gallium Direct3D 10/11 work

If you want to use the Gallium D3D10/11 implementation on Mac OS X, you will need a Gallium driver that can run on Mac OS X. The software renderers probably already work. For hardware acceleration, my proposal is to write a new Gallium driver that uses OpenGL underneath and can thus run on any platform providing OpenGL. I think that implementing such a Gallium driver is easier than implementing D3D10/11 from scratch, and will also benefit Mesa, since it will be possible to test additions to the Gallium interface without needing to write hardware-specific code or writing software rasterization code. I'm not sure if I'll write such a Gallium driver myself. Contributions would be greatly welcome. It's a fun project and certainly much easier than writing an actual hardware driver. Alternatively, you could port the kernel DRM and drivers to Mac OS X and other systems, but that's much harder and much less user friendly. At any rate, nothing stops Wine from also implementing D3D10/11 using WineD3D or OpenGL, and using that if a Gallium driver is not available. Note however that D3D10/11 are totally different from D3D9, so I'm not sure how much you can share (especially if you want a fast implementation, which may be impossible anyway over OpenGL).

About the Gallium Direct3D 10/11 work
by Luca Barbieri 22 Sep '10

22 Sep '10

> If any one wishes to make any comments I'll include those as well as > contacting Luca Barbieri (?) or who ever is relevant to this over at > Gallium3D. Here I am :) As you have read, this is an initial (but working and with most of the code there) implementation of the D3D10/11 APIs. The plan is to ship all the core interfaces (ID3D10Device, ID3D11Device, ID3D11DeviceContext and supporting ones) in Mesa/Gallium, and make it available to native Linux applications. In addition, some Wine dlls will be provided with just the minimal amount of code to hook the Gallium implementation to Wine's HWNDs. They could be shipped either as part of Mesa or as part of Wine. The initial plan would be to ship them as part of Mesa, but if having anything else than Wine ship Wine DLLs is a problem, this could be revisited. Wine would however need to provide all the non-core APIs, such as D3DX and effects, which I don't think anyone will implement for Gallium. The HLSL compiler might come from the GLSL compiler, especially if the Intel team writing it were to decide to support Cg in addition to GLSL. Alternatively Wine could provide it. In the meantime, Microsoft DLLs will be used for all these. > like the fact that it's C++ C++ dramatically increases productivity, especially when implementing COM interfaces, which in C require a lot of unnecessary boilerplate. >needs X11 windows, The current implementation does, but it's very easy to port to anything else supported by Gallium (currently KMS consoles, fbdev and GDI). > and is limited to Mesa drivers, It's limited to Gallium drivers. If desired, this limitation can be circumvented by writing a Gallium driver that uses GL3/4 underneath. I think this could be the best way forward. Even if Wine were to finish its own D3D10/11 implementation over OpenGL, Gallium would still have its own implementation, because going through OpenGL causes massive unnecessary overhead, reliability problems and difficulty of debugging. Furthermore, this allows to provide Direct3D 10/11 features even if Mesa doesn't yet support the corresponding OpenGL features. In fact it's possible that Mesa will make available features like Direct3D 11 tessellation first in the d3d11 state tracker, and only later in the OpenGL state tracker. >from talking to Luca on IRC it sounds > like this is just the "easy" parts like e.g. resource transfers, > texture format conversion and basic draw calls Not at all. This is a full implementation of ID3D10Device, ID3D11Device, ID3D11DeviceContext and all the interfaces required by them, except for deferred contexts and things not yet supported by Gallium. It should support almost everything in the D3D 9.3 feature level, some of the D3D10.0 feature level and almost nothing of the D3D11 feature level. This is mostly due to the current limitations of Gallium. It includes a shader translator which supports all SM4 opcodes, although not all addressing modes and declarations are supported, and it has been tested quite little. Also some things like resinfo and switch/case/default/endswitch aren't yet implemented by most Gallium drivers. It supports texturing with separate resource and samplers by putting every (resource, sampler) pair in a traditional "texture unit". This will change for DX10 hardware once Gallium gets support for distinct resources and samplers. Of course, it's a very young implementation with almost no tests, so it will surely need a lot of small bug fixes to get fully working. It's much more advanced than the Wine implementation, which apparently doesn't seem to even implement OMSetRenderTargets, which is obviously essential for rendering anything. > The *hard* parts are figuring out things > like the shader and effect formats in a clean way. Both are fully documented. Microsoft ships an header for the shaders and source code for Effects11 at least. Shader parsing is already fully done. The "hard part" is doing the Gallium hardware drivers, and making them competitive with the proprietary ones. Implementing Direct3D 10/11 doesn't really have any truly hard part, just a lot of work, especially for the auxiliary parts like the HLSL compiler, D3DX and effects. >Luca took a bit of > a shortcut there by not doing effects at all, and using the DDK for > the shader format. Yes, and that's seem a reasonable move. Effects can be layered on top of the core API and thus are out of the scope of a Gallium state tracker. > That may or may not be ok, depending on what's > actually in the DDK, but I'm not going to take that risk for no good > reason. As far as I can tell, there is no risk. The EULA doesn't even attempt to prevent alternative implementations and it's just an header file, not source code. As far as I can tell, the DDK license does not seem more restrictive than the Windows SDK one > To my knowledge the effect format > isn't documented anywhere.) As far as I know, Microsoft ships full source code for the Direct3D 11 effects implementation at least, and thus it is fully documented in that. Even if Wine developers don't want to just read the Microsoft source code, you can have someone read it and document it. At any rate, reading source code and implementing based on the ideas learned is perfectly legal. Note however that this has _not_ been done for the code in Gallium, especially because it only implements core APIs, and Microsoft (obviously) doesn't release source code for them at all. Even the C++ IUnknown implementation and COM smart pointer is _not_ based on the ones in ATL or MFC, which I haven't even examined. > Suffice it to say that I'm extremely unhappy with > the way D3D development is currently going. I think this is unjustified. Getting a new, working, Direct3D 10 and 11 implementation seems to me quite a positive thing for Wine. It would be great if we could get past this initial impression and have Mesa and Wine work together on this. If you have any concerns, they can be addressed.

Hi Vitaly. Thanks for fixing printing issues. You use sizeof(DEVMODEW) in you patch, but the correct size is: devmodeW->dmSize + devmodeW->dmDriverExtra You should change the FIXME in the comment of get_job_info_2 to a real FIXME, when unicode is FALSE I'm fine with the unicode - only patch for now, as the related code has to move to localspl later (localspl is unicode only). Thanks -- By by ... Detlef

I don't know much about > the subject yet, but I'm reading programming the wdm atm. Firstly I'd like to find a cheap simple USB device that we can actually get working quickly. Earlier I was experimenting with my Blackberry driver, but that's not going far quickly, since it's a multi-protocol device (modem, mass storage, and proprietary protocols, etc.). I've got a USB scanner that's unsupported by SANE, but that needs ReadFile/WriteFile which is a lot of work by itself. Same with USB flash sticks. I can get hold of an iPod but that's probably the most complex, needing to stack on top of USBSTOR.SYS IIRC. Ironically drivers for the easy hardware (USB mice) are unnecessary anyway, since the Linux drivers are good enough, and the Windows drivers probably need to be driven from user-space by bits Wine doesn't have. Maybe I should give up and just get something partially working, add the rest later gradually. Any ideas? Then it's largely a matter of design. I think Alexandre's idea (process per driver, host all USB code in USBD.SYS) is good enough initially. Essentially the first steps would be: 1. libusb integration 2. driver loading hacks 3. driver -> devices lookup 4. usb bus enumeration for devices 5. create pdo and fdo for each device 6. AddDevice to driver 7. perform I/O for IRPs coming down from the driver using libusb I/O functions That should get a very basic driver (that only uses the control pipe) working. I'll try to get some of this done later this week/weekend. Damjan
