Hi Linux kernel folks and Xen folks -- Effective July 5, I will be resigning from Oracle and "retiring" for a minimum of 12-18 months and probably/hopefully much longer. Between now and July 5, I will be tying up loose ends related to my patches but also using up accrued vacation days. If you have a loose end you''d like to see tied, please let me know ASAP and I will do my

At last year''s Xen North America Summit in Boston, I gave a talk about memory overcommitment in Xen. I showed that the basic mechanisms for moving memory between domains were already present in Xen and that, with a few scripts, it was possible to roughly load-balance memory between domains. During this effort, I discovered that "ballooning" had a lot of weaknesses, even though

Hmmm... It appears I never posted the corrected version of this patch so it never made it upstream. See: http://lists.xen.org/archives/html/xen-devel/2011-11/msg00587.html http://lists.xen.org/archives/html/xen-devel/2011-11/msg02145.html It would be good if this very minor fix was also applied to 4.2 (and, if possible, 4.1).

__map_domain_page() *must* be matched with an unmap_domain_page(). These five static inline functions each map a page (or two), then throw away the context needed to unmap it. Each of the changes are limited to their respective functions. In two cases, this involved replacing a large amount of pointer arithmetic with memcpy() (all callers were relying on memcpy() semantics of positive/negative

I've posted this before being subscribed but was thwarted by moderation. I have a new UPS, actual manufacturer unknown. It comes with USB and serial connections, and a CD with windows software and some old unix software for serial support only. I'm using pretty much bleeding edge linux, and I want to avoid rs-232 if possible. Am I hopelessly naive? This is what lsusb says: Bus 006

Hello, Darik Horn sent a pull request adding support for LZ4. LZ4 is supposed to be a very fast compression algorithm, especially when it comes to decompression. I did a quick benchmark with zlib, LZO and LZ4. Now, there are many benchmarks you can find online, but most of them deal with compressing large files. Tinc on the other hand has to compress small packets individually. So I did the

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

Prevent xl from doing any operation if xend daemon is running. That prevents bugs that happened when xl and xend raced to close a domain. Changes since v1: * Add documentation to xl man page. * Permit the execution of commands that don''t modify anything. * Indent error message.

This is a fourth cut of the hypervisor patch of the proposed XENMEM_claim_pages hypercall/subop, taking into account feedback from Jan and Keir and IanC, plus some fixes found via runtime debugging (using privcmd only) and some added comments/cleanup. [Logistical note: I will be out tomorrow (Friday) plus US holidays next week so my responsiveness to comments may be slower for awhile. --djm]

Hi, I managed to run United Devices client on Redhat 6.1 with wine-20010326 (after applying a patch that was posted here), but on Mandrake I get errors (below). It brings up the application, but sometimes gets stuck and doesn't open a System Tray window, as it does on the RedHat. (So once you "minimize" the app it's gone for good). Any help appreciated Zeev $

Hey Linus, Please git pull the following tag: git://git.kernel.org/pub/scm/linux/kernel/git/konrad/xen.git stable/for-linus-3.10-rc5-tag which has two fixes for regressions that occured in v3.10.
