Platforms and Drivers
|
|
=====================
|
|
|
|
Mesa is primarily developed and used on Linux systems. But there's also
|
|
support for Windows, other flavors of Unix and other systems such as
|
|
Haiku. We're actively developing and maintaining several hardware and
|
|
software drivers.
|
|
|
|
The primary API is OpenGL but there's also support for OpenGL ES 1, ES2
|
|
and ES 3, OpenCL, VDPAU, XvMC and the EGL interface.
|
|
|
|
Hardware drivers include:
|
|
|
|
- Intel GMA, HD Graphics, Iris. See `Intel's
|
|
Website <https://01.org/linuxgraphics>`__
|
|
- AMD Radeon series. See
|
|
`RadeonFeature <https://www.x.org/wiki/RadeonFeature>`__
|
|
- NVIDIA GPUs (Riva TNT and later). See `Nouveau
|
|
Wiki <https://nouveau.freedesktop.org>`__
|
|
- Qualcomm Adreno A2xx-A6xx. See `Freedreno
|
|
Wiki <https://github.com/freedreno/freedreno/wiki>`__

|
Software drivers include:
|
|
|
|
- :doc:`llvmpipe <drivers/llvmpipe>` - uses LLVM for x86 JIT code generation
|
|
and is multi-threaded
|
|
- softpipe - a reference Gallium driver
|
|
- :doc:`svga <drivers/vmware-guest>` - driver for VMware virtual GPU
|
|
- `swr <https://www.openswr.org/>`__ - x86-optimized software renderer
|
|
for visualization workloads
|
|
- `virgl <https://virgil3d.github.io/>`__ - research project for
|
|
accelerated graphics for qemu guests
|
|
- swrast - the legacy/original Mesa software rasterizer
|
|

Deprecated Systems and Drivers
|
|
------------------------------
|
|
|
|
In the past there were other drivers for older GPUs and operating
|
|
systems. These have been removed from the Mesa source tree and
|
|
distribution. If anyone's interested though, the code can be found in
|
|
the Git repo. The list includes:
|
|
|
|
- 3dfx/glide
|
|
- Matrox
|
|
- ATI R128
|
|
- Savage
|
|
- VIA Unichrome
|
|
- SIS
|
|
- 3Dlabs gamma
|
|
- DOS
|
|
- fbdev
|
|
- DEC/VMS
