2.6.19 Linux Kernel Released

diegocgteleline.es writes, "After two months, Linux 2.6.19 has been released. It includes the clustering GFS2 filesystem, Ecryptfs, the first developer-oriented version of EXT4, support for the Atmel AVR32 architecture, sleepable RCU, improvements for NUMA-based systems, an "-o flush" mount option aimed at FAT-based hotpluggable media devices (mp3), physical CPU hotplug and memory hot-add in x86-64, support for compiling x86 kernels with the GCC stack protection, and many other things. You can check the full list of changes in LinuxChanges."

Re:Atmel AVR32

The Atmel AVR butterfly is an insanely cheap development platform (20 dollars). It comes with more things than you can shake your fist at. They are also extremely popular and sell out quick so good luck finding one! Speaking of... what do they mean by "AVR support"? They are true microcontrollers with very low clock speeds and very low amounts of storage and memory. Do they mean linux can now run natively on an ATMEGA in the same manner it runs on say a gumstix?! SWEET!!!!

You can get the starter kit from Digi-Key here [digikey.com]. I only knew about this because I bought the AVR starter kit (not AVR32) which was dramatically cheaper - $100 rather than $550. Not sure if this even comes with an AVR32 chip, probably not, but they have that too (133MHz for $37.63 [digikey.com].) Not sure how hard these are to program, but the normal AVR has support for serial in-system programming and if you know your way around an AVR you might be able to use an AVR to make an ISP chip for an AVR32. :)

Most people are familiar with the 8-bit Atmel AVR [atmel.com] microcontrollers, similar to the Microchip 8-bit PIC [microchip.com] microcontollers. The AVR32 [atmel.com] is a 32-bit microcontoller. I believe it was developed by Atmel to be a easy to mirgrate to target to compete with Freescale's 32-bit [freescale.com] offerings, and various manufacturers' low cost 32-bit ARM [arm.com] processors.

Atmel AVR32 not AVR butterfly

[FuzzyDaddy]

The AVR butterfly is from the 8 bit line of microcontrollers. The AVR32 is a much more power beast - the dev kit [atmel.com] sells for $499 ($544 at Digikey [digikey.com]).

Don't get me wrong, I love the AVR microcontrollers - but we're talking a few K of RAM, 8 to 128K of Flash for the program, a smattering of EEPROM and a top speed of 16MHz. I would be impressed if you could run the Linux kernel on that.

Meh, enterprise platforms like Solaris has been doing this for years. If you want to do real HA, it's a very important feature to have.
