Hi,
I have failed to make SAA7134 to work and would be grateful for
any suggestions. The steps thus far are:
Linux-2.4.18-pre8 was patched with:
10_videodev-2.4.18-pre8.diff
11_v4l2-2.4.18-pre8.diff
15_pci-2.4.18-pre8.diff
The kernel was configured with: I2C, I2C bit-banging
Phillips style parallel port adapter, I2C device interface and
I2C /proc interface.
Devfs is in operation (this may be the problem) and V4L2 backward
compatability.
saa7134-20020205 was built and inatalled as well as xawtv-3.69
Various boot and module loading messages are:
i2c-core.o: i2c core module
i2c-dev.o: i2c /dev entries driver module
i2c-core.o: driver i2c-dev dummy driver registered.
i2c-algo-bit.o: i2c bit algorithm module

I have a FlyVideo-3000 card installed and all modules are installed by
hand. Before testing, lsmod shows:
Module Size Used by
saa7134 45120 0 (unused)

and xawtv -hwscan gives:
This is xawtv-3.69, running on Linux/i686 (2.4.18-pre8)

A simple xawtv command produces:

v4l2: framebuffer info

and any attempt to gain further information via strace or gdb
on an unstripped xawtv executable, freezes the system !
Thanks in advance,
