Hi there,
I am modifying the DaVinci audio driver; the kernel is Montavista Pro 4. I am trying to use the mmap() functionality in DaVinci audio driver. When I make a mmap() call from the application, the system either hangs up or gets spurious interrupts continuously(Message printed is-> IRQ: spurious interrupt 1431655765). If I remove all the functionality from the audio_mmap function and just return zero, then also the same results are observed. The debug messages added in the audio_mmap function are also not getting printed. So please tell me what all are possible causes for this behavior and what should I do to implement the mmap() function correctly. If anyone has used the davinci_audio driver with mmap functionality, then please provide your feedback on the same. Thanks in advance for your guidance.
