Just what is âLinuxâ?

| Think about itâtechnically you can break 
| the operating system into many constituent 
| pieces:
|     * Kernel
|     * HAL
|     * Desktop
|     * Subsytems
| and more. You can also break the human 
| body into pieces:
|     * Brain
|     * Eyes
|     * Skeleton
|     * Nerves
|     * Heart
| and more. And like the operating system, 
| each piece is worthless alone. What 
| exactly can you do with the Linux kernel 
| without the other pieces around it? Not 
| much. There are plenty of desktop 
| environments and window managers 
| available, but none of them will run 
| without X Windows, which will not run 
| without the kernel.


Kernel Log: Coming in 2.6.33 (Part 2) - Storage

,----[ Quote ]
| Extended discard support means that Linux 
| now supports ATA TRIM, which can increase 
| SSD lifespan and throughput. New additions 
| to the Linux kernel include HA solution 
| DRBD and drivers for HP, LSI and VMware 
| storage hardware. The new kernel version, 
| expected in early March, also includes 
| many minor improvements to the code for 
| the Btrfs, Ext4 and ReiserFS file systems.



Linux 2.6.33-rc5

,----[ Quote ]
| Hmm. I don't think there is anything earth-
| shaking here, although the i915 KMS changes
| might be noticeable. Notably if you have eDP
| ("embedded DisplayPort" - I think mainly a
| feature you'd find on a new imac), in which
| case it now hopefully works, but more
| commonly if you saw the flickering on your
| laptop panel due to LVDS downclocking (which
| saves power, but is now disabled by default
| until that thing is resolved).


Subject Linux 2.6.33-rc4

,----[ Quote ]
| Hmm. Odd release. Something like 40% of the
| patches are in DRM (mostly  nouveau and radeon,
| both staging, so it's a bit less scary than it
| sounds.  But there's a noticeable i915
| component too). That's all pretty unusual,
| afaik.


Kernel Log: Coming in 2.6.33 (Part 1) - Networking

,----[ Quote ]
| Linux 2.6.33 will have new and improved
| drivers for Wi-Fi chips by Intel, Ralink and
| Realtek. Several drivers for old Wi-Fi
| hardware have been moved to the staging area
| and will probably soon be discarded. New
| additions include various LAN chip drivers
| and several improvements to the network
| stack.


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.

Version: GnuPG v1.4.9 (GNU/Linux)
