similar to: CONFIG_PREEMPT_RT=y possible in Dom0 kernel?

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 waiting for I/O etc. So to

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?

Now that the scheduler can deal with migrate disable properly, there is no real compelling reason to make it only available for RT. There are quite some code pathes which needlessly disable preemption in order to prevent migration and some constructs like kmap_atomic() enforce it implicitly. Making it available independent of RT allows to provide a preemptible variant of kmap_atomic() and makes

Hi. I'm trying to use CentOS4.2 for some audio work (ie. sound editing, etc.). I found a site called PlanetCCRMA (http://ccrma.stanford.edu/planetccrma/software/) and decided that I would give some of their applications a try (hoping that it would not affect my system greatly!). At first I tried the Fedora 3 packages (and they do work), but what I really wanted to do is to download the

I have two models: assets and makes. Make has many assets and an asset belongs to one make. I am calling this part of my asset controller from a search form with the parameters "search" (search term) and "field" (database field heading) which then renders a partial with the search results on it. ######################################################## if

Hi to all, I'm trying to run Battery3 with Wine, but I'm experiencing some problems. 1. When I launch Battery (command line) I see these messages: --- fixme:win:RegisterDeviceNotificationW (hwnd=0x50062, filter=0x32fcb0,flags=0x00000004) returns a fake device notification handle!

Hi folks. My first post over here. While working on a music server optimzation (which ususally goes hand in hand with running pretty low buffers on realtime streams) I figured that certain HiRez flacs were causing XRUNS/hickups on my Linux server platform. The interesting thing is to run into XRUNS even though the stream gets send to a Squeezebox Touch which got a 20s buffer on its receiving

Hi, I am attempting to port the speex library to TI Davinci DM35x Family. My questions are: 1. What is the best ./configure option for it? Is it ARM5e / ARM4 ? when I tried these two the during the compiled a warning "I suppose you can have a [ARM4/ARM5E/Blackfin] that has float instructions?" 2. is there any available demos for the echo cancellation because I can get it

I've been having a problem where ices-kh (the jack'ified version) disconnects from its jack input source unexpectedly. This happens mainly while other jack clients are being started/stopped, or connected/disconnected, but also at other times (e.g. switching between different X sessions). I'm planning to do a bit more work on tuning up the jack setup to see if I can get rid of the

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 +0100 type real

Even better you can set your firefly softphone to auto answer so that you don't even need to be near the pc to answer.

hi, I posted about a week ago, when i had updated to wine1.2-rc6. I had warned that i had seen regressions in wine. This applied to Commercial VST instruments that i have been using in linux for about 2 years. At first, when using Jack-audio-connection kit (after the upgrade) i began to notice certain plugins were now causing Xruns, when they started up. this never used to happen. so i posted.

I wasn't able to find anything in the list archives, please forgive me if this question has been asked before... Our app needs to support multiple media types, so GStreamer would seem to be the obvious choice. However, voice quality is paramount for us. Are there any disadvantages to using the Speex plugin for GStreamer as opposed to directly coding to the Speex API? In
