Linux 4.14 Has Been Released (kernelnewbies.org)

Posted by EditorDavid on from the fearless-coyotes dept.

diegocg quotes Kernel Newbies: Linux 4.11 has been released. This release adds support for bigger memory limits in x86 hardware (128PiB of virtual address space, 4PiB of physical address space); support for AMD Secure Memory Encryption; a new unwinder that provides better kernel traces and a smaller kernel size; support for the zstd compression algorithm has been added to Btrfs and Squashfs; support for zero-copy of data from user memory to sockets; support for Heterogeneous Memory Management that will be needed in future GPUs; better cpufreq behaviour in some corner cases; faster TBL flushing by using the PCID instruction; asynchronous non-blocking buffered reads; and many new drivers and other improvements.
Phoronix has more on the changes in Linux 4.14 -- and notes that its codename is still "Fearless Coyote."

    4.14 or 4.11?

    (I expect the summary will eventually get fixed, followed by someone replying to me “WTF are you talking about?”)

    Linux 4.11 was released last May. 4.14 is the version that's coming out today.

    " the Linux kernel itself lacks any support for any type of journaled filesystem, memory protection, SMP support..."

    I think my bullshit meter just broke. I guess if I knew VB, I could do some low level kernel hacking to fix it. I have proof!

    > OTOH, I have my doubts that they actually have 64TB of RAM.

    I don't. It seems that you can fit 12TB of RAM (128GB*96) into this fairly standard high-end server: http://www.dell.com/en-us/work/shop/povw/poweredge-r930 . I expect that there are niche vendors that sell absolutely _massive_ machines for people who absolutely _must_ work with huge datasets in memory.

    Amusingly, NT4 is where they merged the Kernel and GDI memory spaces in pursuit of graphics performance. Well, they got it, but they also absolutely destroyed NT's reliablity. 3.51 was a rock. Granted, a rock with a 2GB filesystem limit...
