Hi Ferenc,
Thanks a lot for your skeleton driver, I was waiting for this kind of
activity for two years now. I own a Elsa Victory Erazor with a Riva 128
chip and a Micronas VPX 3225 for video in and out, this card up to now
had no V4L support. I tested your skeleton with 2.4.0test1.ac20 and got
the following result:
lsmod:
Module Size Used by
rivatv 6076 0 (unused)
i2c-algo-bit 7560 1 [rivatv]
i2c-core 12928 0 [rivatv i2c-algo-bit]
videodev 4768 0 [rivatv]
cat /proc/bus/i2c*:
i2c-0 i2c Riva 128/TNT/TNT2 bus 0 Bit-shift algorithm
The other commands you mentioned didn't show anything. If i understand
this right the I2C bus is detected, but the chips hanging on the bus (e.g.
VPX3255) are not ? What needs to be done for detecting them ?
Since my Erazor will need some support of the VPX3255 chip when it will
finally be able to access it via I2C, I tried to compile Jens Seidl's
vpx3255 module ( http://www.gilfillan.org/ftp-pub/ ), but it didn't
compile with the new kernel and I2C drivers:
vpx322x.c:353: `I2C_DRIVERID_DECODER' undeclared here (not in a function)
vpx322x.c:353: initializer element for `i2c_driver_vpx322x.id' is not
constant
Some hints on this ?
Is there some activity to have the VPX322x chips as official Linux I2C
devices in the kernel ? - I think a lot of TV cards use them.
Bye Hubertus
