Hi, I am profiling some workloads for the voluntary and involuntary context switches. I am interested in finding out the reasons causing these two types of context switches. As far as I understand, involuntary context switch happens on expiration of time slice or when a higher priority process comes in. While the voluntary switch generally happens when a process is...

I'm getting constantly high numbers of page reclaims & involuntary context switches for dovecot/auth. page reclaims = minor faults = cpu switching back to system-mode, But why is the auth process doing that so excessively? Same for the large number of involuntary context switches... Attached is my "dovecot -n" output. Date: Sun, 07 Nov 2010 20:40:34 +...

HI, Is it possible to specify CONFIG_PREEMPT_RT=y in the Dom0 kernel? It seems that it is forbidden as it is not a menu option in make menuconfig and gets removed if I manually add it to the .config. I want to run a sound server on Dom0 and am having problems with xruns at present, so need to be able to run a preemptive kernel. Thanks, Chris _______________________________________________

Btw., another question that made me wonder already when doing the original patch: why is it that x86-64 properly uses locking for mm_pin_all(), yet i386 doesn''t need to?

...urprise there is public concern about lack of proper scrutiny, the capacity to re-offend and misuse of the legal process by using insanity as a defence. IN the general quest to improve treatment provisions for patients the 2000 Act says: "The new legislation provides for involuntary treatment in the community as an alternative to being an in-patient in a mental health service which reflects contemporary clinical practice and the principle of reform that involuntary treatment must be in the least restrictive form." Perhaps the overwhelmi...

Since version 20020509 I've had nothing but problems, so I decided to reinstall the OS, format all partitions, and reinstall all drivers and programs and updates in the hope that wine will then work correctly. It's taken about 11 hours; I've now installed wine again, but for some reason I had to do make install --ignore-errors; wine did not start after wineinstall; I now get this

Hi, I am running ClamAV process which is invoked by Cron scheduler around 3:00 AM ( Midnight) on remote server running CentOS Linux release 7.6.1810 (Core). Is there a way to measure what was the system resources consumptions like CPU, Network, I/O, Memory and Computing load is being used and is it possible to find out how much time it took to complete the scan? Any help will be highly

hi everyone, first of all i'm using ubuntu. i had the wine menu in the top of all other menus (inside Applications menu), and i dragged it on the bottom of the list under Applications menu (in the "Main Menu" editor), just where it was before deleting it involuntary, but it finished inside the Universal Access menu. then i opened application.menu file where i tried to take this action back, and well, i did that, but in the Universal Access menu remained an item called "wine-wine". i had probably messed something up in the "application.menu"...

It took much more time than I expected, and it is currently less complete than I have hoped, but I've finaly made a first draft of the Markdown Extra spec. You can find it at <http://michelf.com/specs/markdown-extra/ > Currently, the specification defines its goals and a document model for Markdown Extra. It lacks the most important part though: the parsing section, which
