Subject: SMP suspend/resume.
Hi, I managed to make suspend and resume work on SMP system.
The patch following is a bit crude patch, but it begin
to work on my ThinkPad X61 (core2duo system).
TODO:
1. Suspend/resume path it self is simular to AP boot path.
Some of code may be integrated.
2. More context, like MTRR or npx context should be saved on
suspend.
3. Make acpi suspend resume path more ABI aware: needless
register recoverly or special register context saving
(the value itself is usually constant) should be removed.
4. Make same binary module work on both UP or SMP case.
(Or is it time to give up using acpi module on also on i386?)
