Hi, I've tryed AverTV Stereo on my 4.8 cvsuped to STABLE (to get DRM modules) both src and ports. /kernel: bktr0: <BrookTree 878> mem 0xe3023000-0xe3023fff irq 5 at device 9.0 on pci0 /kernel: iicbb0: <I2C bit-banging driver> on bti2c0 /kernel: iicbus0: <Philips I2C bus> on iicbb0 master-only /kernel: iicsmb0: <I2C to SMB bridge> on iicbus0 /kernel: smbus0: <System Management Bus> on iicsmb0 /kernel: smb0: <SMBus general purpose I/O> on smbus0 /kernel: iic0: <I2C general purpose I/O> on iicbus0 /kernel: iicbus1: <Philips I2C bus> on iicbb0 master-only /kernel: iicsmb1: <I2C to SMB bridge> on iicbus1 /kernel: smbus1: <System Management Bus> on iicsmb1 /kernel: smb1: <SMBus general purpose I/O> on smbus1 /kernel: iic1: <I2C general purpose I/O> on iicbus1 /kernel: smbus2: <System Management Bus> on bti2c0 /kernel: smb2: <SMBus general purpose I/O> on smbus2 /kernel: bktr0: AVer Media TV/FM, Philips NTSC tuner. /kernel: pci0: <unknown card> (vendor=0x109e, dev=0x0878) at 9.1 irq 5 systat(vmstat) shows constant IRQ rate at 95 per sec om mux irq5. I suspect this is <unknown card>. Any idea what it is and why it generates IRQ permanently? TV related ports experience: 1. xawtv/motv works unstable (need to get "right" resize to get clear picture, fullscreen is junk, every channel requires adjustment). 2. fxtv works fine (did not test fs yet), but does not have deinterlacing 3. mplayer -tv works fine and gives good picture while height less than 240. As I set it to any value greater than 240 the frame rate drops to 1 fps or so. At the same time the CPU consumption is less than 5%. AverTV spec says that is is able to get full size 720x480 picture, so I do not think that 240 lisne is HW limitation. Any idea what have I missed? Thank you, Sergey. __________________________________ Do you Yahoo!? The New Yahoo! Search - Faster. Easier. Bingo. http://search.yahoo.com
