[RFC] Snapshot boot for OSK5912

[RFC] Snapshot boot for OSK5912

[Hiroki Kaminaga]

Hi,

I made a page describing snapshot boot. Patch and instructions are
available here:

http://tree.celinuxforum.org/CelfPubWiki/SuspendToDiskForARM

Snapshot boot is essentially a resume-from-disk operation, which is a
system resume from a semi-permanent snapshot image stored on flash
memory for OSK5912, that restores the machine to a known running
state. As opposed to a standard resume operation, a snapshot image is
made only once, stored on flash memory, and same image is used
repeatedly, every time the system is powered on.

The purpose of this is to achieve faster startup time of linux on
OSK5912. It is still OSK5912 specific, but would like to hear
comments.


Best Regards,

(Hiroki Kaminaga)

Do you have any startup time comparisons?

Just fyi: The proceedings of this years Linux Symposium are 
online [1]. Volume two contains a paper from Hiroki Kaminaga 
"Improving Linux Startup Time Using Software Resume (and 
other techniques)"

Cheers
