Some warnings may be from an existing SoC .dtsi. Or perhaps the warnings are fixed by another series. Ultimately, it is up to the platform maintainer whether these warnings are acceptable or not. No need to reply unless the platform maintainer has comments.

That might makes sense for the vPCI function, but not the vIOMMU. A secure VIOMMU needs to be running at all times while the guest is running. Perhaps it has no devices it can be used with, but it's functionality has to be there because a driver in the VM will be connected to it. At most "bind" should only tell the already existing secure vIOMMU that it is allowed to translate for a specific vPCI function. Jason

See sendfile() is the designated Linux uAPI for moving data between two files, maybe splice() is also appropriate. The memory file descriptor and your destination file are both a files. So those uAPIs apply. Now what you suggest is to add a new IOCTL to do this in a very specific manner just for the system DMA-buf heap. And as far as I can see that is in general a complete no-go. I mean I understand why you do this. Instead of improving the existing functionality you're just hacking something together because it is simple for you. It might be possible to implement that generic for DMA-buf heaps if udmabuf allocation overhead can't be reduced, but that is then just the second step. Regards, Christian.

Sharing dma-bufs using a driver-private interconnect

by Thomas Hellström

Hi! I previously discussed this with Simona on IRC but would like to get some feedback also from a wider audience: We're planning to share dma-bufs using a fast interconnect in a way similar to pcie-p2p: The rough plan is to identify dma-bufs capable of sharing this way by looking at the address of either the dma-buf ops and / or the importer_ops to conclude it's a device using the same driver (or possibly child driver) and then take special action when the dma- addresses are obtained. Nothing visible outside of the xe driver or its child driver. Are there any absolute "DON'T"s or recommendations to keep in mind WRT to this approach? Thanks, Thomas

The vPCI function is visible to the guest from the very start, even though it is in T=0 mode. If a platform does not require any special CC steps prior to KVM run then it just has a NOP for these functions.

I'm also seeing a splat when running this, see below. I haven't got my head around how this is happening, but I see it when glmark quits at the end of the test.

I'm not sure this is fully true, this could be a Intel thing. When the vPCI is created the host can already know it shouldn't touch the PCI device anymore and the secure world would enforce that when it gets a bind command. The fact it hasn't been locked out immediately at vPCI creation time is sort of a detail that doesn't matter, IMHO. > > It might be reasonable to have VFIO reach into iommufd to do that on > > an already existing iommufd VDEVICE object.

It won't get destroyed until the iommufd closes, so iommufd will be holding the kvm and it will do the final put. Jason

Those aren't valid, you are comparing different functionalities here. Please try using udmabuf with sendfile() as confirmed to be working by T.J. Regards, Christian.
