AMD announced the Brazos-T platform on 9 October 2012. It comprised the 4.5-watt AMD Z-Series APU (codenamed Hondo) and the A55T Fusion Controller Hub (FCH), designed for the tablet computer market. [42] [43] The Hondo APU is a redesign of the Desna APU. AMD lowered energy use by optimizing the APU and FCH for tablet computers. [44] [45]
AMD Software (formerly known as Radeon Software) is a device driver and utility software package for AMD's Radeon graphics cards and APUs. Its graphical user interface is built with Qt [ 6 ] and is compatible with 64-bit Windows and Linux distributions .
Most free and open-source graphics device drivers are developed by the Mesa project. The driver is made up of a compiler, a rendering API, and software which manages access to the graphics hardware. Drivers without freely (and legally) -available source code are commonly known as binary drivers.
The so-called HSA kernel driver resides in the directory /drivers/gpu/hsa, while the DRM graphics device drivers reside in /drivers/gpu/drm [21] and augment the already existing DRM drivers for Radeon cards. [22] This very first implementation focuses on a single "Kaveri" APU and works alongside the existing Radeon kernel graphics driver (kgd).
The Fusion was later renamed the AMD APU (Accelerated Processing Unit). [133] Llano was AMD's first APU built for laptops. Llano was the second APU released, [134] targeted at the mainstream market. [133] It incorporated a CPU and GPU on the same die, as well as northbridge functions, and used "Socket FM1" with DDR3 memory.
Integrated custom ARM Cortex-A5 co-processor [45] with TrustZone Security Extensions [46] in select APU models, except the Performance APU models. [47] Select models support Hybrid Graphics technology by using a Radeon R7 240 or R7 250 discrete graphics card. [48] Display controller: AMD Eyefinity 2, 4K Ultra HD support, DisplayPort 1.2 Support ...
Although AMD strongly considered making the functional part of the ATI drivers "open source", [18] before the merger with AMD, ATI had no plans to release their graphics drivers as free software: Proprietary, patented optimizations are part of the value we provide to our customers and we have no plans to release these drivers to open source.
AMD's proprietary device driver AMD Catalyst is available for multiple operating systems and support for VCE was added to it [citation needed]. Additionally, a free device driver is available. This driver also supports the VCE hardware.
