OpenGL pass-through in QEMU
The OpenGL pass-through in QEMU is used to 'redirect' the OpenGL calls running on the emulated target to the host's native OpenGL library. This brings an important speed up on the execution speed of the target applications that use OpenGL. It is currently available only for x86 targets. It consists on a number of a set of QEMU patches.
Edwin Zhai created an in-depth presentation about the OpenGL pass-through (see attachment below).
