So it seemed to close the file automatically after first irq.
There indeed was a wrong return value in irq handler (in 2.4 it was void).
Corrected it, hopefully we get again further :)
Test this patch.
I'm afraid it still doesn't work. Log attached (with debug=2).
Here is a new patch to test (debug=2). I slightly changed the kfir_read function and also put a BUG() in kfir_close so that the kernel dumps a backtrace in a log when the device closes, so that we can see what closes it.
Looks like we're finally getting somewhere here!
After loading the driver successfully I did
cat /dev/video > x.x
and it actually wrote TS data into that file. After a while I did Ctrl+C to cancel the 'cat', but that completely froze the entire system :-(
The log file is attached.
