Linux Kernel v3

Este Hybrid sleep é basicamente o quê?
É estilo aquilo do windows 8 do boot?

Cumps.

Numa suspensão normal, os dados do computador são guardados na RAM mas se por algum motivo, como falta de bateria, o computador se desligar, perdes tudo. O Hybrid Sleep guarda os dados não só na RAM como no disco para evitar perda de dados em casos como este.
 
É um ponto bem visto, mas neste caso irá demorar mais tempo a suspender certo?

Cumps..

Sim, está no artigo que mostrei da H-Online:

In a short test on a slightly older system with a 250GB hard disk, Suspend-to-Both worked as intended; it required about 16 seconds to go to sleep – four times as long as with Suspend-to-RAM and about as long as is needed for Suspend-to-Disk.
 
Linux 3.7 arrives with broader ARM support, optionally signed kernel code

If you're the sort of Linux user who won't even wait for a packaged distribution to update, you'll be happy to hear that Linux 3.7 has hit the servers. The updated foundation puts ARM chips on a footing much closer to that of their x86 counterparts: the code now supports a true multi-platform model that will load on multiple ARM designs. It's also the first instance of Linux to natively support 64-bit memory for newer ARM-based hardware.

No matter what circuitry you're running, there's also a big boost to security by allowing signed kernel modules that will only accept approved code, even if a curious user gains root access. There are many (many, many) more tweaks and tune-ups in store, so those who like to push their OS limits can check release details from Linus Torvalds and developers at the source links.

Bye bye Intel 386

Merge branch 'x86-nuke386-for-linus' of git://git./linux/kernel/git/tip/tip

Pull "Nuke 386-DX/SX support" from Ingo Molnar:
"This tree removes ancient-386-CPUs support and thus zaps quite a bit
of complexity:


24 files changed, 56 insertions(+), 425 deletions(-)


... which complexity has plagued us with extra work whenever we wanted
to change SMP primitives, for years.


Unfortunately there's a nostalgic cost: your old original 386 DX33
system from early 1991 won't be able to boot modern Linux kernels
anymore. Sniff."


I'm not sentimental. Good riddance.

The Best Features Of The Linux 3.10 Kernel

The Linux 3.10 kernel is slowly getting ready for release in the coming weeks. If you haven't been closely following Phoronix in the past few months of Linux 3.10 feature development, here's a brief overview of some of the best and most interesting features to be found in the next version of the Linux kernel.

- The BCache SSD/HDD caching framework has been merged. For those with systems boasting a mix of solid-state drives and traditional hard drives, BCache allows for SSDs to act as a cache to larger but slower traditional HDDs.

- Power management improvements are to be found in the next kernel release. Reducing the Linux kernel's power consumption and making it more competitive to Windows and OS X is always welcome. With the Linux 3.10 kernel is a new AMD frequency-sensitivity power-save bias that should work well on AMD CPUs. Separately, there's ARM improvements too for those out of the x86 world. On a semi-related note, the Linux kernel now has full dynticks support.

- Various DRM driver changes, but perhaps most interesting in the open-source Linux graphics driver world with the Linux 3.10 kernel is UVD video decoding support finally being present. The Linux 3.10 kernel is needed in conjunction with an updated Mesa/Gallium3D stack for taking advantage of hardware-based video playback exposed over VDPAU with Gallium3D.

- Better Intel Haswell Linux support and performance for the brand new CPUs.

- File-system improvements including skinny extents for Btrfs, F2FS changes, and extra XFS protection.

- Many other changes. This kernel actually yields the biggest Linux changes in years.

Linux 3.10 out with better SSD caching and Radeon support

Linux 3.10 was released by Linus Torvalds last night, bringing with it a new method of SSD caching and some upgrades to the Radeon graphics driver. "This release has been pretty typical and not particularly prone to problems," Torvalds wrote in his e-mail announcing the release. "No major new subsystems this time around, although there are individual new features."

As you may recall, Linux 3.9 (released in April) included an experimental feature called dm-cache that allows SSDs to act as caches for other storage devices. An additional SSD caching technology known as Bcache was also in the works for more than a year and has now merged into the Linux kernel with the newly released 3.10.

"Linux 3.10 will include the 'block-layer cache' Bcache, which can be used to configure one disk as a cache for another disk; a fast SSD, for example, could be used as a cache for a slower hard drive with more capacity," H-Online editor Thorsten Leemhuis wrote in his thorough roundup of the new kernel version."This kind of SSD cache can speed up access to frequently read data and take on write requests until a quieter moment when they can be written to the slower disk."
Early benchmark tests have not found a clear winner between dm-cache and Bcache. Tests have found "that each solution works well in some situations and unexpectedly badly in others—clearly, they all could still stand to improve a bit," Leemhuis wrote. "t remains to be seen how well Bcache, which Google has already been using in-house for some time, handles situations outside of a data processing centre's clearly defined parameters."

The two most significant changes in Linux 3.10 are the aforementioned SSD caching "and support for the newer Radeon graphics cores' video decoder," Leemhuis wrote. "The Radeon driver in the Linux kernel now offers interfaces for interacting with the Unified Video Decoder on Radeon HD 4000 and later HD graphics cards. An open source UVD driver which uses this interface will be included in the next major revision to Mesa 3D (version 9.2 or 10.0). The kernel now supports the graphics chip on the recently released Richland processor family, otherwise known as A4, A6, A8, and A10 series APUs. Linux can also now address Radeon Hainan GPUs."

Other changes allow newer Intel GPUs to be overclocked. Systems with Intel GPUs can also now wake from standby faster.
Looking ahead, Linux 3.11 will likely include patches that let the Radeon driver make better use of power management features.

Kernel 3.11 RC2 já anda por aí.

É o kernel que estou a usar de momento e para já feedback muito positivo.
Ao contrário do 3.10 que é stable, com o 3.11 todas as keys FN do meu portátil funcionam (brilho, touchpad, sleep, etc).

E como é que se porta a nivel de consumo de energia? li algures que este ultimo kernel está a gastar energia com niveis mt elevados.

Ao contrario do teu feedback o meu é muito negative testei ele só para ver as novidades e ó coisa mais bugada xD testei apenas no meu desktop...
Depois testo o 3.10... Neste momento estou com o 3.09 e não tem dado nenhum problema.

Abraços.

Que problemas é que tiveste?
Eu já estou a usar o 3.10 e o único problema que tive foi com a placa gráfica (Nvidia GeForce 6100).
Coloquei uma Nvidia GeForce 210 e ficou tudo a bombar.
No portátil (Packard Bell TJ65) não tive qualquer problema.

O Kernel 3.10 ainda não testei.
Os problemas que o outro deu foram vários deu problemas no Gnome Shell e Cinnamon problemas de drives etc...

Abraços.
