| |
The first [draft] version of software suspend released.
It's against 2.1.125, full of FIXMEs, TODOs and XXXs.. only for i386 [yet]... but basically works.
What is does: It makes possible to suspend a machine even without apm on any platform that linux supports. It shrinks memory [drops unused buffers, inodes, etc and swaps out as many pages as it can] then from the rest it makes a copy in memory [so that its state changes we don't mind -- we have to save the image]. Then it reboots. It resumes the following way: after initializing kernel before execing init we check wheter we have a saved image [can be disabled]. If so we load its pages and copy them to their original place, then we reactivate current task, registers and it may continue its work.
What I need: ppl interested about this feature, testing, poiniting for bugs, resolving my notes [whether that solution works ok].
Upgrading to recent kernels should be here soon [I hope]. I just wanted to make my first release and get finally feedbacks.
