Subject: [GIT PULL] various IOMMU updates for 2.6.29
Hi Linus,
The following changes since commit 6680598b44ed3c0052d155522eb21fc5a00de5f3:
Ingo Molnar (1):
Disallow gcc versions 3.{0,1}
are available in the git repository at:
git://git.kernel.org/pub/scm/linux/kernel/git/joro/linux-2.6-iommu.git for-linus
The changes include:
- VT-d updates for 2.6.29
- multiple device assignment support for KVM from Han Weidong
- refactoring of the VT-d functions for KVM into a generic iommu api
and necessary KVM changes (required for amd iommu support in KVM)
- AMD IOMMU support for the iommu api (makes AMD IOMMU usable for pci
device assignment in kvm)
- other AMD IOMMU updates for 2.6.29 including:
+ cleanups and minor improvements
+ a debugfs stats interface
This code touches areas of various subsystem maintainers. Because it
would have required some special care if we merged this code over the
different subsystems I agreed with David Woodhouse and Avi Kivity that I
send you a seperate pull request for this stuff. The iommu api was
reviewed, discussed with and acked by Greg Kroah-Hartman.
Please pull.
