Hi all, I have dom0 and a guest on the same cpu: cpu0. However, when I look at interrupts and ipis (with Xenperf) I get the following. There is nothing going on Cpu3 so why the high number of IPIs? I have done a reset of the counters, but after I run my workload on the guest cpu3 IPIS go from 0 to 210276 (Dom- has only 1 cpu and xm vcpu-list shows the other 3 cpus in blocked state. The

Hi all, Which is the practical (from your experience) limit of the number of X100P cards installed in a single Asterisk box? Asterisk can work reliable with 6 X100P cards in the same box? Anyone know when the 4 ports FXO Digium card will be available on the market? Many thanks, Dan P.S. Please do not aswer with RTFG ...tried before without success...:-))

...with no one to reclaim them soon enough under polling mode. Multiple choices have been suggested, and some actually implemented in some drivers: . A timeout thread that just reclaims periodically . Reclaim some descriptors at the beginning of or before returning from the tx routine . Turn on tx interrrupts per transmit ring. . Have a single NIC-wide interrupt shared for all tx ring''s transmit completion events, and turn that interrupt ON. . Have a high water mark/low water mark for triggering the reclaiming from the transmit routine. . Some internal tunables to choose one or a combination...

...ile doing 20 iterations of make -j6 of kernel works. C) Xen + 2.6.32.24 pvops dom0 + 2.6.37-merge-window kernel DomU: Videograbbing while doing 20 iterations of make -j6 still freezes the machine without a trace after a short while. An other interesting thing is the interrupt rate i see in /proc/interrrupts for the xhci controller, i measured for 5 minutes each time. In situation: A) About 3200 Interrupts/second B) About 3200 Interrupts/second C) About 7800 Interrupts/second, what would be 7.8 interrupt per ms which seems to work as long as you don''t stress the rest to the limit. Which pro...

The delay scheduler dequeue routine has some code cut&pasted from the TBF scheduler that caused a race with E1000 when ring got full. It looks like net schedulers should never be calling netif_queue_stopped because the queue may get unstopped by interrrupt or receive soft irq (NAPI) which races with the dequeue in the transmit scheduler. Also, if requeuing the packet fails, it is probably

yes, the cause of BSOD 0x101 is that watchdog time interrupt was not received by the vcpu in a certain timeout in Windows kernel . this is taken place especially in vista kernel. Generally speaking, we have some ways to fix this, one is that we an write a programme whitch can intercept the trigger of BSOD 0x101, on the other word, we make kernel don''t care the watchdog time interrrupt.

Hi all, We are running Asterisk 1.2.7.1 on our Dell Poweredge 2850 and are having massive sound quality issues. We are experiencing call quality issues for our remote location, namely calls cutting out and breaking up for our agents. The two main issues seem to be 'popping' and 'dropping' - popping would be pops and crackles on the line, where dropping would be complete audio

I'm confused by the page documenting tryCatch and friends. I think it describes 3 separate mechanisms: tryCatch (in which control returns to the invoking tryCatch), withCallHandlers (in which control goes up to the calling handler/s but then continues from the point at which signalCondition() was invoked), and withRestarts (I can't tell where control ends up). For tryCatch the docs say

Hi All I am using version 0.3.13.3 and since there is no logging support for win32 application. I was wondering if it was possible to get any kind of logging at all. I have tried to these two options 1. Stream redirection using "mongrel_rails start -c C:/myspace/snapshot -p 4111 -t 70 -e production -P log/mongrel-1.pid > C:\temp\mongrel-1.log" The console print the output stream
