ClearFog PCIe not working with v2.21-core126
by Luís Mendes 15 Feb '19

Hi all, I noticed that the ipfire kernel configuration doesn't include the driver for I2C GPIO expander chip PCA9655 which is a required dependency for the PCIe controller. Since the PCIe card reset and clock request signals are provided by this expander chip, without such driver, Linux simply ignores the entire PCIe subsystem. I've tested that adding the following options to the kernel configuration fixes the issue: CONFIG_GPIO_PCA953X=y CONFIG_GPIO_PCA953X_IRQ=y Unfortunately IRQ option is only available is module is complied as kernel built-in. IRQ is relevant, because the USB subsystem relies on it to monitor USB port OverCurrent conditions, through the same GPIO expander chip. Can these kernel configurations option be added to ipfire? It would be relevant to allow for additional Ethernet ports. Regards, Luís Mendes
