Note:
PCIe: Tegra TX1 does not have any path from AHB-DMA or APB-DMA engines to PCIe IP as PCIe is connected directly to MSELECT and AHB-DMA and APB DMA engines only interact with IPs connected to respective AHB and APB buses. So it is not possible to use either AHB or APB engines for PCIe.

EGL and OpenGL ES Support
EGL is an interface between Khronos rendering APIs, such as OpenGL ES, and the underlying native platform window system. It handles graphics context management, surface/buffer binding, and rendering synchronization. EGL enables high-performance, accelerated, mixed-mode 2D and 3D rendering using other Khronos APIs.
L4T supports the EGL 1.4 specification, Khronos Native Platform Graphics Interface (EGL 1.4 Specification).
The OpenGL ES driver in this release supports the following OpenGL ES specifications:
•OpenGL ES Common Profile Specification 2.0
•OpenGL 4.5
For more information on OpenGL ES, see the Khronos OpenGL ES API Registry.
