http://phk.freebsd.dk/patch/cpu_elan.patch http://phk.freebsd.dk/patch/CPU_ELAN.4 The major new things are: ELAN_XTAL option now called CPU_ELAN_XTAL ELAN_PPS option now called CPU_ELAN_PPS /dev/led/error for the error LED. More LEDs can be configured on the GPIO pins, for instance: sysctl machdep.elan_gpio_config="-----LLLE--lp--------LL---------" Configures active high LEDS on GPIO5,6,7,21 & 22, an active low LED on GPIO11. These will appear as devices "/dev/led/gpio5" etc. The 'p' on GPIO12 and 'E' on GPIO8 are PPS input and PPS-echo configurations (enabled by CPU_ELAN_PPS option). The led(4) interface is of course not only useful with lamps, you can use it with any sort of gadget connected to a GPIO pin. I can not guarantee that these patches will make it into FreeBSD 5.2. -- Poul-Henning Kamp | UNIX since Zilog Zeus 3.20 phk@FreeBSD.ORG | TCP/IP since RFC 956 FreeBSD committer | BSD since 4.3-tahoe Never attribute to malice what can adequately be explained by incompetence.
