Than you have another problem. If you get such a warning with a buffer of 658kB, interrupts wasn't deliver to the dvb-driver for more than 85..106ms. > 5) > > You asked for dumps.

Thanks, I need only the dump with the running application and with the i2c-address 0xc (tda10021). I forgot, that exists some more devices on the i2c-bus. The windows driver uses a small buffer (188kB), in odd/even buffer mode. The line width is 188 Byte. The line count is a multiple of 512 like the current linux driver. The interesting thing is: the register 0x12 of the tda10021 is set to 0xa1. Before my change, the linux driver has used 0xa1 without a CI/CAM and 0xa0 with a CI/CAM. Some of the registers (0x20 and 0x2c), which are also responsible for the output configuration of the tda10021, make no sense. The value 0x95 is to often and always on a multiple of 4 within the dump. Can you create such a dump again? Currently, I've no idea why it works in single buffer mode and why not with odd/even buffers. - Hartmut _______________________________________________ linux-dvb mailing list linux-dvb@xxxxxxxxxxx http://www.linuxtv.org/cgi-bin/mailman/listinfo/linux-dvb
