AMD Outlines HSA Roadmap: Unified Memory for CPU/GPU in 2013, HSA GPUs in 2014

AMD's CTO Mark Papermaster just put up this slide that shows its HSA (Heterogeneous Systems Architecture) roadmap through 2014. This year we got Graphics Core Next, but next year we'll see a unified address space that both AMD CPUs and GPUs can access (today CPUs and GPUs mostly store separate copies of data in separate memory spaces). In 2014 AMD plans to deliver HSA compatible GPUs that allow for true heterogeneous computing where workloads will run, seamlessly, on both CPUs and GPUs in parallel. The latter is something we've been waiting on for years now but AMD seems committed to delivering it in a major way in just two years.

iBoot 2.5 - Unified Graphics Support

type="html">

Today, iBoot has received a major update.  No longer will there be multiple versions of iBoot, but one unified version for any supported Intel CPU with either ATI or NVIDIA graphics.  The new version is a permanent replacement for all previous versions of iBoot, including iBoot-NVIDIA, iBoot-ATI, iBoot-ATI-5xxx, and iBoot-Supported. 

Download iBoot

We've rolled in the latest pre-release version of Chameleon 2.0 RC5, and for ethernet, the latest beta version of Lnx2Mac's RealtekRTL81xx.kext.  For desktops and laptops using unsupported Intel CPUs and graphics, a legacy version of iBoot can be downloaded here.

As always, follow the iBoot + MultiBeast method for installation.  Please note that iBoot is an installation tool, and is not intended as a substitute for installing Chameleon to your hard drive or EFI partition. 

If iBoot has helped you, please consider a contribution to support further development.  Thanks in advance, and enjoy!

UPDATE: iBoot 2.5.1 now includes 10.5.0 kernel and updated USB support for 10.6.5.

New Unified Realtek Onboard Audio Solution: ALC8xxHDA

type="html">

Introducing MacMan's ALC8xxHDA.kext, a single combined LegacyHDA replacement for Realtek ALC888, ALC887/888b, ALC889, ALC885/889a, and ALC892 high-definition audio codecs.  In order to initiate audio, this driver must be combined with a DSDT from the DSDT Database or HDAEnabler.  For any codecs other than the native ALC885/889a, AppleHDA Rollback must also be used.  All options now available in the latest MultiBeast.

To update from an existing MultiBeast LegacyHDA + AppleHDA rollback:

1. Delete LegacyHDA from /Extra/Extenisons
2. Open MultiBeast
3. Select ALC8xxHDA + AppleHDA Rollback + System Utilities
4. Reboot

To update from an existing MultiBeast VoodooHDA:

1. Delete VoodooHDA from System/Library/Extensions.
2. Open MultiBeast
3. Select ALC8xxHDA + AppleHDA Rollback + System Utilities
4. Reboot

Realtek ALC888, ALC887/888b, ALC889, ALC885/889a support:

OUTPUTS: Analog Front Headphone/Green Line-out, Orange Line-out, Grey Line-out, Digital SPDIF-OUT
INPUTS: Analog Pink Microphone, Blue Line-in, Digital SPDIF-IN

Realtek ALC892 support:
OUTPUTS: Analog Front Headphone/Green Line-out, Digital SPDIF-OUT

INPUTS: Analog Pink Microphone, Blue Line-in, Digital SPDIF-IN

Please report your results with this new method in the forum.  Special thanks to complx for the ALC8xxHDA logo.  Enjoy!
