Linux 3.11 added respective support, so I think we should follow suit. 1: xen: add LZ4 decompression support 2: libxc: add LZ4 decompression support Signed-off-by: Jan Beulich <jbeulich@suse.com>

WARNING: This is not compatible with the previous lz4 patchset. If you''re using experimental compression that isn''t in mainline kernels, be prepared to backup and restore or decompress before upgrading, and have backups in case it eats data (which appears not to be a problem any more, but has been during development). These patches add lz4 and lz4hc compression

Hi, so here it is, LZ4 compression method inside btrfs. The patchset is based on top of current Chris'' for-linus + Andi''s snappy implementation + the fixes from Li Zefan. Passes xfstests and stresstests. I haven''t measured performance on wide range of hardware or workloads, rather wanted to publish the patches before I get distracted again. I''d like to ask

Hello, Is there some version of FLAC that allows very very fast encoding (i.e. able to process at least 150 MB / second of .wav input data on a standard computer : laptop computer, Core i5/i7, Windows 7 64 bit, 8 GB RAM) ? (It's ok to have a compression ratio which is a little bit lower than traditionnal FLAC) I'm looking for something which is between FLAC (very good ratio, slower than

I am running XEN on CentOS Linux release 7.8.2003 I have a Debian 7, and two Gentoo DomU Guests running fine. I am trying to get an Ubuntu 20.04 DomU Guest running but I get this error when trying to run the netboot kernel image xc_dom_probe_bzimage_kernel unable to LZ4 decompress kernel I understand that CentOS Xen does not support LZ4 decompression. Is there a workaround for this?

Hi, I am dealing with very large datasets and it takes a long time to save a workspace image. The options to save compressed data are: "gzip", "bzip2" or "xz", the default being gzip. I wonder if it's possible to include the pbzip2 (http://compression.ca/pbzip2/) algorithm as an option when saving. "PBZIP2 is a parallel implementation of the bzip2

All, having successfully compiled and set up Dovecot 2.2.29.1 on my Thecus NAS as a newbie without any further hassle, and already imported an external mail archive of ~15 GB into a lz4-compressed mdbox (with impressive performance on the old Intel Atom CPU!), I stumbled into a minor, but reproducible issue that might well be already known, but I haven't managed to find any pointers

I'm a long time user of openssh and I was wondering if there is any work towards supporting alternative compression methods in openssh like LZ4? Regards, Mark -- Mark E.

Compression has some problematic interactions with encryption that OpenSSH seems to have handled far before anyone else (by having it off by default).

Hi, Running 9.2-PRERELEASE #19 r253313 I got the following panic Fatal trap 12: page fault while in kernel mode cpuid = 22; apic id = 46 fault virtual address = 0xffffff827ebca30c fault code = supervisor read data, page not present instruction pointer = 0x20:0xffffffff81983055 stack pointer = 0x28:0xffffffcf75bd60a0 frame pointer = 0x28:0xffffffcf75bd68f0

I've been trying to upgrade Dovecot-ee package (on EL6/x86_64) from 2.2.15.8-1 to 2.2.16.2-1. It's complaining on these two dependencies: liblz4.so.1 libtextcat.so.0 These would both seem to be related to plugins, and don't seem to be required as package dependencies by the RPM from what I can see from the SRPM. Anyone know what packages I need to satisfy these dependencies?
