Hello All,
I need to implement a gtod/clocksource/clockevents implementation for the Atmel ARM AT91SAM9261 CPU, and I am looking for some kernel (interface) documentation about these mechanisms.
I already investigated the 'examples'/implementations of other architectures in the kernel, but that did not really help me... I also looked at the patch for the AT91RM9200 CPU posted by David Brownell... I hacked something which now makes the RT kernel to boot, but the time-of-day warps several minutes per second, back and forward in time... ;-)
So, Can anybody please give me pointer to some useful documentation and/or examples?
The reason behind this initiative is to make the RT-preempt patch compile and work on this architecture. Currently the GENERIC_TIME is not set, which results in several unresolved externals at compile time, and I believe the best way to fix this is to implement proper gtod/clocksource/clockevents to allow the enabling of GENERIC_TIME
Kind Regards,
