Hi!
I am writing a device driver of a video capture card.
The kernel is 2.2.13-rtl2.0.
The BIOS of my PC allocates the same irq number to
the video capture card and the on-board sound device.
The ALSA(Advanced Linux Sound Architecture)-driver is used for
the on-board sound device.
Activating both devices resulted in hanging down the system.
Is it possible to share the same interrupt between the RTL driver
and the plain linux driver ?
I know two plain linux drivers can share the same interrupt
by setting SA_SHIRQ bit when request_irq() is called.
Any help or comments will be very appreciated.
Bye.
