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@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.

78 Happy Hacking!
