similar to: AMD iommu

Introduce a new flag to disable iommu emulation on old iommu systems. This patch is taken from my v4 patch queue, which is till pending, to make old or non-iommu system to run cleanly without interfered by iommuv2 codes. This might be helpful to isolate iommuv2 code in debugging unstable regressions. The reset part of v4 will be re-based. Thanks, Wei Signed-off-by: Wei Wang

Tom, next time please cc Jerg as the AMD IOMMU maintainer. Joerg, any chance you could review this? Toms patches to convert the AMD and Intel IOMMU drivers to the dma-iommu code are going to make my life in DMA land significantly easier, so I have a vested interest in this series moving forward :)

Hi Christoph, I quit my job and am having a great time traveling South East Asia. I definitely don't want this work to go to waste and I hope to repost it later this week but I can't guarantee it. Let me know if you need this urgently. Thanks, Tom On Sat 10 Aug 2019, 3:20 p.m. Christoph Hellwig, <hch at infradead.org> wrote: > On Sun, Jun 23, 2019 at 11:19:45PM -0700,

Dave, Joerg, Robin: is there any chance we could at least pick up patches 2 and 4 ASAP as they are clearly fixes for current deficits, even without the amd conversion?

Changeset 20514 implemented deallocation for msi interrupt remapping entries. Attached patch adds the same support for amd iommu to fix a xen crash on amd iommu systems.

Hi, amdgpu + IOMMU + SME is now working for me on 5.7, yay! But, it is broken on torvalds master, boo. On boot, depending on which exact commit I test, it either hangs immediately (with built-in driver, before starting initramfs), displays some errors then hangs, or spams the screen with many amdgpu errors. I bisected the black screen hang to: commit dce8d6964ebdb333383bacf5e7ab8c27df151218
