I have tried to profile a program that uses the linux-dvb drivers and find that many of the ioctl's break.
Looking at the kernel code I see that there are a few interruptable waits which perhaps are related to the problem. Especially the READ_STATUS ioctl. Under profiling this ioctl always returns successfully but the status is always 0. However, the front end seems to tune successfully, and data gets delivered, but it is just the status ioctl's which appear to break when profiling is enabled (gcc -pg). Is this a known problem? _______________________________________________ linux-dvb mailing list [email protected] http://www.linuxtv.org/cgi-bin/mailman/listinfo/linux-dvb
