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 --with-gallium-driver-dir="`pwd`/src/gallium/targets/pipe-loader/.libs" \ 7 --enable-debug --enable-texture-float --with-dri-drivers= --disable-dri \ 8 --disable-opengl --disable-egl --disable-vdpau --disable-xvmc --disable-gbm \ 9 --disable-gallium-llvm 10 make 11 12 *** Then we create some symlinks to mesa: 13 ln -s "`pwd`/lib/gallium/libd3dadapter9.so.0.0.0" /usr/lib/ 14 ln -s "`pwd`/lib/gallium/libd3dadapter9.so.0" /usr/lib/ 15 ln -s "`pwd`/lib/gallium/libd3dadapter9.so" /usr/lib/ 16 ln -s "`pwd`/include/d3dadapter" /usr/include/ 17 18 *** Clone and build a patched wine 19 git clone git (a] github.com:iXit/wine.git 20 ./configure 21 make 22 23 *** And finally we create some symlinks to our patched wine files: 24 for f in d3d9.dll gdi32.dll user32.dll wineps.drv winex11.drv; 25 do 26 mv /usr/lib/wine/$f.so /usr/lib/wine/$f.so.old 27 ln -s "`pwd`/dlls/`basename -s .dll $f`/$f.so" /usr/lib/wine/ 28 done 29 30 *** Activating it within wine 31 regedit 32 Navigate to HKCU\Software\Wine\Direct3D 33 If it's not there, create it 34 Create a new DWORD value called UseNative 35 Set its value to 1 36 37 Every Direct3D9 program will now try using nine before wined3d 38 39 If you want to selectively enable it per-exe instead, use the key: 40 HKCU\Software\Wine\AppDefaults\app.exe\Direct3D\UseNative 41 where app.exe is the name of your .exe file 42 43 44 *** HOW IT WORKS *** 45 46 Nine implements the full IDirect3DDevice9 COM interface and a custom COM 47 interface called ID3DAdapter9 which is used to implement a final IDirect3D9Ex 48 COM interface. 49 ID3DAdapter9 is completely devoid of window system code, meaning this can be 50 provided by wine, Xlib, Wayland, etc. It's inadvisible to write a non-Windows 51 backend though, as we don't want to encourage linux developers to use this API. 52 53 The state tracker is compiled, along with pipe-loader, into a library called 54 libd3dadapter9.so. This library loads pipe_[driver].so drivers on demand and 55 exports a single symbol for getting a subsystem driver. Currently only DRM is 56 supported. 57 This library is then linked to the library implementing the IDirect3D9[Ex] 58 interface and the actual Direct3D9 entry points (Direct3DCreate9[Ex]) 59 60 The implementation of IDirect3D9[Ex] lies within wine and coexists with 61 wined3d. It's loaded on demand and so if it's not there, it doesn't have any 62 drivers or something else is wrong, d3d9.dll will automatically revert to using 63 wined3d. 64 Whether or not it's even tried is determined by 2 DWORD registry keys. 65 > HKCU\Software\Wine\Direct3D\UseNative 66 > HKCU\Software\Wine\AppDefaults\app.exe\Direct3D\UseNative 67 The former is the global on-switch. The latter is per-exe. 68 69 The driver search path can be set at configure time with 70 --with-gallium-driver-dir and overridden at runtime with D3D9_DRIVERS_PATH. 71 Debugging information can be gotten with the WINEDEBUG channels d3d9 and 72 d3dadapter, and state_tracker debug information can be gotten with NINE_DEBUG. 73 Help on NINE_DEBUG is shown through NINE_DEBUG=help 74 75 Finally, the ID3DPresent[Group] and ID3DAdapter9 interfaces are not set in 76 stone, so feel free to hack on those as well as st/nine. 77 78 Happy Hacking! 79
