Save Power with Linux

,----[ Quote ]
| Linux has its own advantages. It sure is 
| geeky, it is powerful and now you can even 
| do your bit to help the deteriorating 
| environment. The folks at lesswatts.org 
| have devised a number of ways to save power 
| with Linux. The results have been obtained 
| from continued stress-testing on all 
| mobile, desktop and server machines and 
| have been favorable so far. The kernel used 
| for these tests are the 2.6.22 version but 
| they are hoping that the power-saver 
| features will go into the kernel 2.6.23.

Mandriva: nouveau now default NVIDIA driver

,----[ Quote ]
| Nouveau is now used by default as the driver 
| for NVIDIA cards, when proprietary driver is 
| not in use [2].



Linux 2.6.33-rc3

,----[ Quote ]
| It's been quiet due to the holidays, so -rc3
| is reasonably small despite  being a few days
| over the normal one-week mark. And most of the
| changes  are pretty trivial, although both
| ext4 and reiserfs had some trouble in  -rc2,
| hopefully all fixed now.


Linux 2.6.33-rc2 - Merry Christmas ...

,----[ Quote ]
| .. or wahetever it is you'll be celebrating
| today/tomorrow.
| And if you aren't celebrating anything at
| all, but instead sitting in your dark
| basement feeling lonely and bored, you can at
| least try out the latest -rc kernel. Because
| it's better than moping around doing nothing.


Nouveau: A 2.6.33 Surprise

,----[ Quote ]
| Linus has released the 2.6.33-rc1 prepatch,
| closing the merge window for this development
| cycle. This kernel has a few features which
| will shake things up, with dynamic tracing
| being near the top as far as I am concerned.
| But, perhaps, the most interesting addition is
| one that almost nobody expected: a reverse-
| engineered driver for NVIDIA graphics chipsets
| called âNouveau.â


Nouveau To Go Into Linux 2.6.33 Kernel!

,----[ Quote ]
| Wow, the day has come, open-source fans with
| NVIDIA hardware that run Linux have quite the
| present this holiday season. Yesterday there
| was the first DRM pull request for the Linux
| 2.6.33 kernel that brought many changes to the
| ATI/AMD and Intel DRM along with other core DRM
| improvements (such as to the TTM memory
| manager). These changes were quite significant
| and we even called it a great present in the
| Linux 2.6.33 kernel.
| These DRM changes were accepted, but Linus
| Torvalds went off on a bit of rant wanting
| Nouveau merged into the kernel. A discussion
| ensued and after blaming Nouveau's lack of
| upstreaming on wanting the kernel/user-space
| API to potentially change in the future and
| then with Red Hat disclosing the Nouveau
| microcode problem that seemed to be pretty
| much that and we had not expected any
| immediate activity on the matter.


Linus Torvalds Accepts DRBD into Linux Kernel

,----[ Quote ]
| Linus Torvalds, lead developer of the Linux
| kernel community, has merged DRBD, an open
| source data replication solution, into Linux as
| a fully supported component. After exactly 10
| years of ongoing development work - software
| developer Phil Reisner wrote the first line of
| code on December 8, 1999 - Torvalds'
| acknowledgment means DRBD has become a fixture
| on the storage market.


Linus Wants Nouveau Merged Into Kernel

,----[ Quote ]
| This morning the first DRM pull request went
| in for the Linux 2.6.33 kernel that brings
| many nice graphics changes for Intel,
| ATI/AMD, and VMware users. Anything for
| NVIDIA hardware through Novueau was not
| mentioned as there is no readied support, but
| as we stated in our article this morning, its
| unlikely to see Nouveau's DRM in the mainline
| kernel before the Linux 2.6.34 kernel. This
| is even though Fedora has been shipping
| Nouveau support for a few releases now and
| even Canonical is pulling in Nouveau KMS
| support for Ubuntu 10.04.


Part 2 Of Nouveau Saga: The Microcode

,----[ Quote ]
| Following a feature-packed DRM pull request
| this morning for the Linux 2.6.33 kernel,
| Linus Torvalds became frustrated that the
| Nouveau driver for supporting NVIDIA hardware
| was still not to be found in this most recent
| pull request. Linus wants Nouveau in the
| mainline kernel especially as Red Hat has
| already been shipping this free software
| driver in Fedora for two releases.


Nouveau Companion 41

,----[ Quote ]
| Just in time for the holidays is a new Nouveau Companion newsletter to update
| the community on the status of this open-source 2D/3D NVIDIA driver that is
| written by clean room reverse-engineering of NVIDIA's binary driver. It has
| been a while since Nouveau Companion 40, but there is still active work going
| into this X.Org driver. Among the topics covered in the 41st edition of the
| Nouveau Companion is kernel mode-setting, Gallium3D, layering GEM on top of
| TTM (similar to the GEM-ified TTM Radeon driver), and thermal monitoring code
| for the Nouveau driver.
| Well, I bet most of you did not expect me to show up shortly before the end
| of the year with yet another TiNDC. There has been some turmoil regarding my
| job. At first it was too much work followed by a somewhat unexpected folding
| of the company. So I had to find a new job, which is why I never turned up
| for quite some time.
