Subject: [Qemu-devel] [patch 18/24] QEMU/KVM: notify _EJ0 through _SEJ OperationRegion
Date: Tue, 11 Mar 2008 17:12:09 -0300	[thread overview]
Message-ID: <20080311201418.642592930@localhost.localdomain> (raw)

The _EJ0 method is executed by the OS once it has successfully finished
device removal. Inform that event through IO port space so QEMU 
can free the associated data.
