Well, I started thinking about possible solutions for mpc824x by looking at the only available sleep implementation for ppc in the kernel - powermac. As was suggested I looked under drivers/macintosh. As an example I took powerbook_sleep_grackle() (I think, grackle is also installed in "blue and white" G3's, right?). There I see various calls to pmu_request() with macros as parameters and some comments, so, most things can be understood and mapped to another hardware (if still relevant under the new power-management interface). But then come some things that I don't understand: /* Ask the PMU to put us to sleep */ pmu_request(&req, NULL, 5, PMU_SLEEP, 'M', 'A', 'T', 'T'); So, what exactly does this command do? Next I'll dig the real low-level stuff low_sleep_handler(); I am already excited about getting my hands dirty with ppc assembly:-) Thanks Guennadi --- Guennadi Liakhovetski
