Mantis DMA interrupt with FTRGT flag?

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



Hi Manu.

Here is Mantis debug messages at verbose level 7:

Jun 28 20:01:53 koivu kernel: -- Stat=<3c00000a> Mask=<802>
--<DMA><FTRGT><RISCI><Unknown> Stat=<30000000> Mask=<802>
Jun 28 20:01:53 koivu kernel: mantis_dma_xfer (0): last block=[2]
finished block=[3]
Jun 28 20:01:53 koivu kernel: demux: skipped 148 bytes at 9497: 00 ..
Jun 28 20:01:53 koivu kernel: TS packet counter mismatch. PID=0x2b2
expected 0xa got 0xb

What FTRGT message means?

Those errors come seemingly randomly at blocks 0, 1, 2 and 3:
56 Stat=<20000000>
68
71 Stat=<10000000>
73 Stat=<30000000>

So above, Stat=<00000000> is hidden.

With bttv, FTRGT means something like FIFO overflow.
How can I make the error more rare?

Regards,
Marko Ristola
