[PATCH][VT] Multithread IDE device model ( was: RE: [PATCH]Make IDE dma tranfer run in another thread inqemu)
Keir:
This is to to make the IDE device model multithreading so that
the VMX domain IO access completion (triggering DMA operation) can be
asynchronize with the completion of DMA operation. With this patch we
get 8%--14% performance gain for kernel build.
Thanks,
eddie
