Subject: [Qemu-devel] [PATCH 0/1] ahci: do not remap clb/fis unconditionally
Date: Tue, 12 May 2015 18:36:12 -0400 [thread overview]
Message-ID: <1431470173-30847-1-git-send-email-jsnow@redhat.com> (raw)
This continues the IOMMU fix from 2.3, where we should not attempt
to remap the CLB or FIS RX buffers if the AHCI device is currently
running.
The same applies to migration: keep our mitts off these registers
unless the device is supposed to be on.
Does not impact backwards compatibility for the AHCI device.
