1 Quickstart Guide 2 3 *** Configure and build mesa 4 CFLAGS="-m32" CXXFLAGS="-m32" ./autogen.sh --prefix=/usr \ 5 --with-gallium-drivers=nouveau,r600,swrast --enable-nine \ 6 --enable-debug --enable-texture-float --with-dri-drivers= --disable-dri \ 7 --disable-opengl --disable-egl --disable-vdpau --disable-xvmc --disable-gbm \ 8 --disable-llvm 9 make 10 11 *** Then we create some symlinks to mesa: 12 ln -s "`pwd`/lib/gallium/libd3dadapter9.so.0.0.0" /usr/lib/ 13 ln -s "`pwd`/lib/gallium/libd3dadapter9.so.0" /usr/lib/ 14 ln -s "`pwd`/lib/gallium/libd3dadapter9.so" /usr/lib/ 15 ln -s "`pwd`/include/d3dadapter" /usr/include/ 16 17 *** Clone and build a patched wine 18 git clone git (a] github.com:iXit/wine.git 19 ./configure 20 make 21 22 *** And finally we create some symlinks to our patched wine files: 23 for f in d3d9.dll gdi32.dll user32.dll wineps.drv winex11.drv; 24 do 25 mv /usr/lib/wine/$f.so /usr/lib/wine/$f.so.old 26 ln -s "`pwd`/dlls/`basename -s .dll $f`/$f.so" /usr/lib/wine/ 27 done 28 29 *** Activating it within wine 30 regedit 31 Navigate to HKCU\Software\Wine\Direct3D 32 If it's not there, create it 33 Create a new DWORD value called UseNative 34 Set its value to 1 35 36 Every Direct3D9 program will now try using nine before wined3d 37 38 If you want to selectively enable it per-exe instead, use the key: 39 HKCU\Software\Wine\AppDefaults\app.exe\Direct3D\UseNative 40 where app.exe is the name of your .exe file 41 42 43 *** HOW IT WORKS *** 44 45 Nine implements the full IDirect3DDevice9 COM interface and a custom COM 46 interface called ID3DAdapter9 which is used to implement a final IDirect3D9Ex 47 COM interface. 48 ID3DAdapter9 is completely devoid of window system code, meaning this can be 49 provided by wine, Xlib, Wayland, etc. It's inadvisible to write a non-Windows 50 backend though, as we don't want to encourage linux developers to use this API. 51 52 The state tracker is compiled, along with pipe-loader, into a library called 53 libd3dadapter9.so. This library loads pipe_[driver].so drivers on demand and 54 exports a single symbol for getting a subsystem driver. Currently only DRM is 55 supported. 56 This library is then linked to the library implementing the IDirect3D9[Ex] 57 interface and the actual Direct3D9 entry points (Direct3DCreate9[Ex]) 58 59 The implementation of IDirect3D9[Ex] lies within wine and coexists with 60 wined3d. It's loaded on demand and so if it's not there, it doesn't have any 61 drivers or something else is wrong, d3d9.dll will automatically revert to using 62 wined3d. 63 Whether or not it's even tried is determined by 2 DWORD registry keys. 64 > HKCU\Software\Wine\Direct3D\UseNative 65 > HKCU\Software\Wine\AppDefaults\app.exe\Direct3D\UseNative 66 The former is the global on-switch. The latter is per-exe. 67 68 The driver search path can be set at configure time with 69 --with-gallium-driver-dir and overridden at runtime with D3D9_DRIVERS_PATH. 70 Debugging information can be gotten with the WINEDEBUG channels d3d9 and 71 d3dadapter, and state_tracker debug information can be gotten with NINE_DEBUG. 72 Help on NINE_DEBUG is shown through NINE_DEBUG=help 73 74 Finally, the ID3DPresent[Group] and ID3DAdapter9 interfaces are not set in 75 stone, so feel free to hack on those as well as st/nine. 76 77 Happy Hacking! 78
