I have noticed that my pvr-350 is generating about 400 interrupts per second when apparently idle. I know this was a possible issue in (way) past versions of driver. I lost track of the thread from long ago so I don't know what ever became of it. It was something about vsync if I remember correctly.
I am running X over the TV-out and figure that might be what they are for. It appears that encoding a video stream only generates maybe 10-30 IRQs per second. My new pvr-150 is completely silent unless in use. Everything appears to be working fine. I figured I would mention it just incase an old bug happens to be rearing its head again. I am using 'procinfo -dn1' btw incase you need to know. Also, semi related but probably more of a kernel question, what happens to the IRQ counter when it overflows? My box has been up about 2 days and has generated ~80 million irqs since then. By crude calculations my computer would overflow a 32 bit integer in about 100 days. The box has operated that long without reboot before (rare but...). Are we talking about a silent rollover or a kernel oops/eek/panic? It might have explained some weirdness with the previous incarnation(knoppmyth r4v5) of mythtv. When left without reboot for long periods of time, the ivtv drivers told mythtv tuners were in use but nothing was recording. I could do the 'dd' tests and stuff fine. A warm reboot fixed it and I have not seen the same problem in current incarnation.
