Subject: [git pull] IOMMU updates for 3.3-rc1
Hi Linus,
The following changes since commit dc47ce90c3a822cd7c9e9339fe4d5f61dcb26b50:
Linux 3.2-rc5 (2011-12-09 15:09:32 -0800)
are available in the git repository at:
git://git.kernel.org/pub/scm/linux/kernel/git/joro/iommu.git next
The most important changes for this merge window in the IOMMU tree are:
* Generic support for multiple page-sizes. The iommu-layer now
gets a bitmap from the iommu-driver about the supported
page-sizes and the generic code splits the map-requests
accordingly (by Ohad Ben-Cohen)
* Device-group code, the iommu-drivers now export information
which devices the iommu hardware can safely isolate and which
not. Devices which can't be safely isolated with the hardware
belong to the same group. This will be used by the VFIO
driver (by Alex Williamson)
* AMD IOMMU driver extensions to support the version 2 of
AMD IOMMU hardware. With hardware that can make use of it this
is a step towards demand-paging for device-dma (by me)
* Other random fixes and improvements
You also find a few patches in this pull-request which are from the PCI
tree. I pulled in the patches into the x86/amd branch from the
pri-changes branch kindly provided by Jesse Barnes. The patches in this
branch should also be in the PCI tree. I had to do this because patches
in the PCI tree renamed some constants I use in my new code. Doing it
this way makes sure that everything still compiles when this tree is
pulled.
The top-commit of the next branch on my local machine is
f4e8a3c5e33972dc78f042f9e839b33e213325d0
When I did a test-pull of the branch against v3.2 there was a conflict
in drivers/pci/hotplug/acpiphp_glue.c (due to the changes I pulled in
from the PCI tree). Please let me know in case you want me to fix that.
Thanks,
Joerg
