The Adreno series of graphics processing units (GPUs) are semiconductor intellectual property cores developed by Qualcomm and used in various of their SoCs. The core was initially developed under the Imageon brand name by ATI Technologies, which was acquired by AMD in 2006. After the buyout in 2008, Qualcomm renamed the Imageon products to Adreno. Adreno is an anagram of Radeon.
The company offers the chip in various flavors as component of their Snapdragon SoCs:

Operating system support
There are proprietary drivers for the Linux-based mobile operating system Android available from Qualcomm themselves. There are no drivers available for any other Linux-based operating systems, but through libhybris, it became possible to use the Android drivers. Especially mer-based systems such as the Sailfish OS rely on this solution.
There is an ongoing endeavor of writing free and open-source device drivers for the Adreno series of GPUs called
freedreno. The project utilizes Gallium3D, but the code can of course be ported to Mesa as well.
As of September 2013, freedreno has been adopted into mainline Linux, and will be part of Linux 3.12.
The Imageon (previously ATI Imageon) is a line of media processors developed by ATI providing graphics acceleration and other multimedia features for handheld devices such as mobile phones and Personal Digital Assistants (PDA).
Designed as system-on-a-chip (SoC), the Imageon line of media processors was introduced in 2002 to bring integrated graphics (from 2D in 2002 to 3D in latest products) to handheld devices, cellphones and tablet PCs.
The system-on-a-chip design incorporates an embedded CPU core, baseband sub-system CPU interface, memory controller, power management (ATI PowerPlay), internal RAM and stacked RAM with memory buffer, two display engines (for dual monitors on cellphones), imaging engine, image/video/audio capture engine, TV and audio output, dual digital signal processors for audio and video, and video acceleration engine.
The Imageon line was rebranded under AMD, after AMD acquired ATI in Q3 2006, as AMD Imageon, with official claims to have shipped nearly 250 million Imageon units to customers since 2003. However as a result of company restructuring, AMD divested the handheld chipset business starting from the second quarter of 2008, thus the line is deemed officially discontinued.
At the end of 2008, the handheld branch was sold off to Qualcomm, following an earlier sale of the Xilleon branch to Broadcom. AMD retained the Imageon name and will provide support for existing customers, although no future Imageon products will be introduced.
