comp.os.linux.embedded - Linux operating system on embedded hardware.
Hello I am little confused about the memory managent in Embedded Linux. My understanding is that, one of the properties of embedded OS it predictability. And the demand-paging/swapping is something that brings in un-predictability. But in practical situations how is demand-paging handled in embedded linux ? Is it disabled? Are all the pages needed by a process loaded earlier itself?? Is MMU used in such embedded devices? Can we have a system where MMU is enabled but demand-paging/swapping is disabled ? Just how does the whole thing work in embedded Linux system like a mobile phone???? thanx Vinay
Hi All, Embedded Devices don't have swap device, so how demand paging is done? - A
Does anyone have experience with power management on embedded linux systems? Is it mature and working? I specifically need my platform to do a hibernate where the system state is saved to a ram disk and then restored very quickly to wake up. I know there are alot of issues with getting various devices to sleep and wake but I think we can handle that. I'm mostly interested in the kernel itself. Any tips are appreciated. Thanks, Clark
