I might be repeating myself, but I think what you do here is a no-go and reimplements core system call functionality by a way which we certainly shouldn't allow. T.J's testing shows that sendfile() seems to work at least in one direction. The other use case can certainly be optimized. So if you want to improve this work on that instead.

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

Does sendfile achieve zero-copy? > sendfile reduces memory copies (from 2 to 1) for network sockets, > but still requires one copy and cannot achieve zero copies. Well why not? 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. What you have here is some new BIND operation against the already existing vdevice as we discussed earlier. > 16. *attach vdev > 17. *setup CC viommu > 18 *tsm_bind > 19. *bind > 20.*Attest > 21. *GHCI get CC info > 22. *get CC info > 23. *vdev guest req > 24. *guest req > 25.*Accept > 26. *GHCI accept MMIO/DMA > 27. *accept MMIO/DMA > 28. *vdev guest req > 29. *guest req > 30. *map private MMIO > 31. *GHCI start tdi > 32. *start tdi > 33. *vdev guest req > 34. *guest req This seems reasonable you want to have some generic RPC scheme to carry messages fro mthe VM to the TSM tunneled through the iommufd vdevice (because the vdevice has the vPCI ID, the KVM ID, the VIOMMU id and so on) > 35.Workload... > 36.*disconnect(Unbind) > 37. *GHCI unbind > 38. *Unbind > 39. *detach vdev unbind vdev. vdev remains until kvm is stopped. > 40. *tsm_unbind > 41. *TDX stop tdi > 42. *TDX disable mmio cb > 43. *cb dmabuf revoke > 44. *unmap private MMIO > 45. *TDX disable dma cb > 46. *cb disable CC viommu I don't know why you'd disable a viommu while the VM is running, doesn't make sense. > 47. *TDX tdi free > 48. *enable mmio > 49. *cb dmabuf recover > 50.workable shared dev This is a nice chart, it would be good to see a comparable chart for AMD and ARM Jason
