Linux: First Release Of nftables
,----[ Quote ]
| Netfilter maintainer Patrick McHardy
| recently announced a first alpha-release
| of nftables, slated to eventually replace
| iptables as the standard Linux packet
| filtering engine. Nftables aims to
| simplify the kernel ABI, reduce code
| duplication, improve error reporting, and
| provide more efficient execution, storage
| and updates of filtering rules. Patrick
| began with a high level overview of the
| three pieces that comprise the firewall,
| "the kernel provides a netlink
| configuration interface, as well as
| runtime ruleset evaluation using a small
| classification language interpreter. libnl
| contains the low-level functions for
| communicating with the kernel, the
| nftables frontend is what the user
| interacts with." An insightful overview
| can be found on lwn.net.

R600/700 Mesa Driver Picks Up Blit Support
,----[ Quote ]
| While a blitter module was introduced for
| Gallium3D that uses the 3D engine for
| blitting, this doesn't help those without blit
| support that are still running the "classic"
| Mesa driver stack. Over the night, however,
| blit support has arrived for the ATI R600/700
| Mesa driver. This support arrived in the form
| of three commits (1, 2, 3) that increase the
| driver's code-base by around 2,000 lines of
| code.

Mesa 7.8 In March; Mesa 8.0 To Have OpenGL 3
,----[ Quote ]
| This week in the Mesa world Gallium3D feature
| levels came about and a new EGL state tracker
| was released. The week though is not over and
| there are more announcements coming out for
| this free software OpenGL stack used on Linux
| and other operating systems.

The State Of OpenGL 3.x in Mesa Core
,----[ Quote ]
| While ATI R600 users only recently received
| OpenGL 2.0 hardware support within the open-
| source Radeon 3D stack and there is many more
| OpenGL extensions to be implemented just not
| for the ATI Mesa driver but the other DRI
| drivers as well, Brian Paul has published a
| document that lays out the current state of
| OpenGL 3.x within the classic Mesa core. This
| document lays out what core Mesa supports and
| not necessarily that any of the drivers are
| implementing the said support at this time.
| Granted, with Mesa not really being very
| performance-efficient at this time or capable
| of running most games, a majority of users
| will be waiting for the OpenGL 3.x state
| tracker for Gallium3D.

Mesa 7.6 Gets Pulled Into Ubuntu 9.10
,----[ Quote ]
| Mesa 7.6 does not drastically change the level of
| performance compared to the older Mesa snapshot
| that was found in Ubuntu Karmic up until today,
| but there are improvements in a few areas. In the
| below example from an Intel G43 system we
| compared the Ubuntu 9.04, Ubuntu 9.10 Beta, and
| Ubuntu 9.10 Beta with Mesa 7.6 performance using
| the Phoronix Test Suite. With the Urban Terror
| game there were performance improvements already
| to be found in Ubuntu 9.10 compared to Ubuntu
| 9.04 with Mesa 7.4, but this latest code steps up
| the performance one bit more.
