| Name | Current Status |
|---|---|
| General | |
| Website localization | Website translators are needed! Please contact your language maintainer. |
| Operating system localization | Depends on language. Ask appropriate language maintainer. |
| Software compatibility | Please help us to test what already works in ReactOS. Share your tests here or report bugs: JIRA |
| Win32 Subsystem | |
| Win32 DLLs | See Testman reports |
| Win32k |
Support for User mode printer drivers: unimplemented. |
| Core | |
| Bootloader | In a rather good shape, needs further development in terms of adding some more features and fixing existing. We switched to the NT-compatible booting method with r43273. Old bootmethod has been removed in r52491. |
| Kernel | |
| Memory manager (MM) | In a process of a soft rewrite, resulting in a functional equivalent of NT's (2003's) memory manager, without made up ROS-specific implementations and assumptions. |
| Object manager (OB) | Nearly perfect. Functionally equivalent to 2003's OB. Tested code, works very good. Experienced only bugfixes during the last two years. |
| Common Cache (CC) | Stays as it is for now, adapting to the changing memory manager. There exist three rewrites: No-Cc (a version of the kernel which does no caching at all, very slow); cache-manager-rewrite, started long time ago, but still occasionally maintained in a working condition; arty-cc by Art Yerkes, totally new Cc with a good, separated from Mm architecture, WIP. |
| File system support - File Systems | |
| FAT32 | Needs a rewrite of a file system driver (fastfat), test it against windows 2003. Started in r38693 |
| NTFS | Completely missing (not to count a very simple stubbed IFS driver). It would make sense to use NTFS 3g from Linux and develop an own driver, also should be developed against Windows 2003. |
| Ext2 | Support in the kernel is missing for a good/known to work driver. |
| Driver support | |
| PNP manager | Supports all driver operations. However, the functional logic is not always the same as in Windows. Implementation is also still very different from Windows PNP. A complete rewrite of the kernel part is planned in the future. |
| VXD | Not planned at all, it's a Win9x thing. |
| 2D/3D Graphics | |
| GDI | Pretty good shape overall, missing Metafile support. Relies heavily on win32k. |
| GDI+ | Completely shared with Wine, relies on GDI. |
| OpenGL | Uses software rendering by default, via Mesa3D ICD driver. API is almost complete, only few wgl* functions are missing. Can load various ICD drivers and works fine on WinXP too. |
| ReactX | D3D9, D3D8 & DDraw APIs are supported via WineD3D - wrapper translating DirectX functions to OpenGL. |
| Sound | |
| Portcls | Is a class driver for the audio driver subsystem. MIDI support is missing. HW testing needed for port driver implementation (IPortWavePci & IPortWaveRT). Portcls / sysaudio also need testing & bugfixing for WaveIn (audio recording). |
| Sysaudio | Handles access to the audio port drivers by managing the device interfaces. Needs to map multiple audiostream to a virtual audio pin in kmixer. Portcls / sysaudio also need testing & bugfixing for WaveIn (audio recording). |
| Wdmaud | Is a kernel mode component of wdmaud.drv . Implements the Wave / Mixer / MIDI API. Needs MIDI APIs implemented and WaveIn support + Mixer support. |
| Kmixer | Performs mixing / conversions of streams. Currently very poorly implemented. Needs Kernel FPU float saving support before more work can be done. |
