[Voyage-linux] ALIX leds and voyage kernel v3.14.12

[Ted Hess]

Hi all -

Again, it seems that the ALIX leds are broken in the latest experimental kernel build (voyage v3.14.12_15.0) -- /sys/class/leds is an empty directory. The problem is the PCI GPIO driver, selected by GPIO_CS5535, is missing. This driver cannot be selected or built in the kernel via menuconfig, or even by manually editing .config, due to a recursive dependency caused by the LEDS_APU option in the driver/leds/Kconfig settings.

Fix: In driver/leds/Kconfig, in the LEDS_APU option, change
    select GPIOLIB –> depends on GPIOLIB    (note: select causes a reverse dependency)


Run ‘make menuconfig’ again and select the PCI GPIO driver for the AMD CS5535 in the Drivers –> GPIO section. Rebuild the kernel, install and boot -- you now have ALIX leds!

As an added benefit, the netdev led trigger now appears to be fixed in this kernel version and you can set VOYAGE_LEDS=”YES” once again in your voyage-util config file (/etc/default/voyage-util).

Regards,
/ted
