[Qemu-devel] [PATCH 0/1] ahci: do not remap clb/fis unconditionally

From: John Snow

Date: Tue, 12 May 2015 18:36:12 -0400

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

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.

For convenience, this branch is available at:
https://github.com/jnsnow/qemu.git branch ahci-iommu

This version is tagged ahci-iommu-v1:
