| |
Seems that my first per-IRQ stack hack is running stable now! Cool!!
For SMP it alloc 4kbyte * 64 interrupt * 32 cpu = 8Mbyte of ram. I' ll find a way to alloc the memory only for running CPU soon. Now I am worried about stability of the mechanism.
For UP the space alloced by the irq stack is 64kbyte so it doesn' t harm at all.

I' d like to hear comments about this hack. I' d like if people would try the patch in a SMP system too. But backup your HD before try it (should not cause fs corruption but sure can lock your machine at any time)!
