Bug 415531 – sys-kernel/uksm-sources - Full Linux sources including the Gentoo patchset and UKSM patch

• Product: Gentoo Linux
• Status: UNCONFIRMED ---

[Description Gao Xiang 2012-05-12 01:12:04 UTC]

the UKSM project replace the official KSM algorithms with a hash algorithms.  This patch brings a big improvement of KSM.  According to an unofficial test done on CPU Intel core 2 Q9300, the official's KSM merging speed is about 260M/s, while the average merging speed in the real work is only several tens of megabytes per second.  The UKSM's merging speed achieve 477MB/sec ~ 923MB/sec.  For pages without duplicated data, the scanning speed can reach 627MB/sec ~ 2445MB/sec.
The project's homepage is at: http://kerneldedup.org
This project is started and maintained by several Chinese people right now.  It has released several stable versions.  Because of lacking in contributers the project's maintainer is now mainly focused on develop. Works expanding to English community and merging with mainline will be done in the future.

Reproducible: Always

Don't use pastebin as it expires after a while. Please attach your ebuilds using the bugzilla functionality

And please don't CC random arches on your own. Let bug-wranglers handle your bug

DESCRIPTION="Full sources including the Gentoo patchset and UKSM patch for the ${KV_MAJOR}.${KV_MINOR} kernel tree"

Don't use variables here. Also, it's entirely unnecessary to refer to specific versions in generic descriptions.

OK, I will fix it.
the fixed version (with your and other people's advice) is temporary stored here (in pastebin, I was advised using paste service instead of upload temporary versions as attachments. I will upload the final version here as attachment.)
