saa716x driver

saa716x driver

[Marcel Sebek]

Hi.

I have a card named "AverMedia TV Hybrid Speedy PCI-E" and I'm tryiing
to make it working under linux. I've found the drivers at

http://jusst.de/hg/saa716x/

The drivers hangs on loading, this is the output:

saa716x_pci_init (0): found a Avermedia H788 PCIe card
SAA716x Hybrid 0000:03:00.0: PCI INT A -> GSI 17 (level, low) -> IRQ 17

100 mS!
saa716x_i2c_hwinit (0): Adapter (c000) SAA716x I2C Core 0 RESET

this repeats many times, modprobe hangs for a few minutes

saa716x_i2c_hwinit (0): Adapter (c000) SAA716x I2C Core 0 RESET
saa716x_eeprom_header (0): ERROR: Header size mismatch! Read size=8 bytes, Expected=65535
saa716x_eeprom_data (0): ERROR: Header Read failed <-1>

DVB: registering new adapter (SAA716x dvb adapter)

I've also tried various int_type values but with no success. After some
experiments, I've found that reverting patches "Fix BUS ordering" and
"Fix swapped I2C buses" fixed the hang during module loading, now it
the output is:

After that, there are created some device nodes in /dev/dvb/adapter0
(demux0, dvr0, net0) but no frontend device node. It looks like the
drivers are not yet fully working. Is there a chance that the card will
be usable under linux?
