Hi Max, Thanks for the comments. I looked through the existing CIMaX driver and came to the conclusion that it can be implemented either with the IRQs or then just to rely on the polling like the USB devices have to do. I don't think it's that important, as the user probably will not add/remove th

Hello, In hardware design, the CI host controller is wired with GPIO_0 of CX23885. The GPIO_0 can be configed as the interrupt source. Interrupt mode in PCIe driver is more faster than poll mode to detect CAM insert/remove operations etc. >Add CI support for DVBSky T980C. > >I used the new host d
