Changeset 37466 in vbox for trunk/src/VBox/VMM/VMMAll/IOMAllMMIO.cpp

Timestamp:

Message:

VMM,Devices: Automatically use a per-device lock instead of the giant IOM lock. With exception of the PIC, APIC, IOAPIC and PCI buses which are all using the PDM crit sect, there should be no calls between devices. So, this change should be relatively safe.
