[News] Linux 2.6.28 Gets Graphics Execution Manager

Hash: SHA1

GEM Patches Submitted For Linux 2.6.28-rc1

,----[ Quote ]
| Earlier this month we shared that Intel's GEM would be in Linux 2.6.28 and 
| today the patches that add this have been submitted to Linus Torvalds for 
| inclusion into the Linux 2.6.28-rc1 kernel. GEM, the Graphics Execution 
| Manager, is the kernel memory manager for graphics drivers on Linux that 
| replaced Tungsten's TTM in Intel's driver and it's beginning to appear 
| elsewhere.     



Intel's GEM Coming In Linux 2.6.28 Kernel

,----[ Quote ]
| Since May when Intel first introduced their Graphics Execution Manager after
| X.Org developers were enraged over Tungsten's TTM memory manager and its
| development challenges, we've been talking about GEM several times since
| then.
| Intel's Graphics Execution Manager is a kernel memory manager for graphics
| processors and has since overtaken TTM in what will become the de facto
| standard for GPU memory management. A technical explanation of GEM can be
| found here.


The State of Kernel Mode-Setting

,----[ Quote ]
| All of the kernel-based mode-setting excitement in Fedora 9 was limited to
| those using Intel's integrated graphics hardware. With Fedora 10 not only can
| Intel users benefit but so can those with ATI Radeon hardware. Jerome Glisse
| has been working on Radeon kernel mode-setting code since December of last
| year, and in recent months David Airlie and Adam Jackson have joined in on
| this work. For those using an ATI R300 GPU to R500 will have kernel-based
| mode-setting support enabled by default in this next Fedora release. A few
| months back AMD had released a new AtomBIOS parser to the open-source
| community, which is being used for the KMS driver and should enter the
| mainline Linux kernel -- likely with Linux 2.6.28.


Kernel Log: 2.6.27 nearing completion; Btrfs to be added to the kernel?

,----[ Quote ]
| Chris Mason has transferred the source code of the experimental Btrfs file
| system into a Git repository. This move is intended to make it easier for
| other kernel hackers to evaluate the file system and to stimulate discussions
| about incorporating it into the Linux main development branch. Mason believes
| that it would be best to continue development of the file system from now on
| within the framework of the official Linux kernel. If this were to happen, it
| should be with the caveat that Btrfs is not intended for everyday use, in
| much the same way that developers treat the Ext4 file system, which kernel
| hackers have been working to complete within the framework of the Linux main
| development branch since version 2.6.19.

Version: GnuPG v1.4.9 (GNU/Linux)
