I has hacking on swsusp2 to ppc for whole day. Here is the update swsusp2-asm.S. First I can true suspend is ok, the data and CPU context are full write to disk. Then in resume, the copyback function works. How I know it? I'm adding printk before do_swsusp2_lowleve finished, I has printf the r1, That is the pointer to cpu context, it must right on resume, when resume it'll triger xmon, I d pm_sleep_storage, and check the pointer, I see that same things, So I true the copyback is ok, at least the cpu context memory has backed. very tire day. The current problem that is, In resume, It stop with all register (r0-r32) is zero. I don't known where I am. :) > I'll keep you informed of my progress I'm too. :) -- Hu Gang / Steve Linux Registered User 204016 GPG Public Key: http://soulinfo.com/~hugang/HuGang.asc
