| |
I'm writing a driver for DVB-C PCI receiving cards these days and I found a tricky problem of interrupts. Since kernel-2.6.19 the interrupt handlers get rid of "struct pt_regs*" argument and I think it will be easy for me to modify the driver to fit for the recent kernel. I simply delete the "struct pt_regs *" argument of my interrupt handler and compile the driver again. But then I met a rather tricky problem. I cann't get the PCI intterrupt now! I found that the chip on the card actually had generate an interrupt and it should not be the hardware problem. I'm get seriously confused. My driver works well under kernel-2.6.18 but not generates a single interrupt signal when works above kernel-2.6.19. Does anybody meet similar problems? Sincerely Yours, Lost Graden. 1,21. 2008
