I had added irqpoll to the domU when it should have been dom0.Now I have irqpoll in the dom0, tuner interrupts are being sent to the domU, and more importantly no longer getting the "nobody cared" message. # cat /proc/interrupts CPU0 16: 440 Phys-irq saa7130[0] 256: 6187 Dynamic-irq timer0 257: 0 Dynamic-irq resched0 258: 0 Dynamic-irq callfunc0 259: 689 Dynamic-irq xenbus 260: 296 Dynamic-irq xencons 261: 6624 Dynamic-irq blkif 262: 32 Dynamic-irq blkif 263: 24 Dynamic-irq blkif 264: 713 Dynamic-irq eth0Thinking about the IRQ sharing, the SATA controller was giving about 6000 interrupts/second yesterday during expansion of a raid array, that is obviously quite exceptional, but sending so many unwanted interrupts via pciback/front is not a good thing, I'll have to do some tests later to see if it's a disastrously bad thing, for now I've moved the PCI card into the slot with less shared interrupts. dvbscan still won't talk to the device but femon does, my second tuner is currently in a different machine, so I can compare and contrast. # femon -h FE: Philips TDA10046H DVB-T (DVBT) status | signal 0% | snr 100% | ber 0001fffe | unc 00000000 |I connected the aerial to it, and despite what dvbscan/femon said, I thought I'd try a channel scan with mythtv anyway and it found one mux and has started populating the EPG, it should find several muxes (it's fed from the same amplifier as my other machine/tv) but I'll class that as "initially working" :-) _______________________________________________ Xen-devel mailing list Xen-devel@xxxxxxxxxxxxxxxxxxx http://lists.xensource.com/xen-devel
