...ms to write its internal memory which is mapped to host memory space via pci transaction. But there is no mapping in IOMMU''s page table, so that page fault occurs in IOMMU. I think that MMIO resource mapped via p2m table should be mapped via IOMMU''s page table too. In other word, XEN_DOMCTL_memory_mapping hypercall should update not only p2m table, but also IOMMU''s page table. What do you think about this? Does anyone see the same issue? /var/log/message on guest linux: Aug 28 11:53:28 localhost kernel: Emulex LightPulse Fibre Channel SCSI driver 8.2.0.22 Aug 28 11:53:28 localhost kerne...

Hi Guys, ich_force_enable_hpet() in linux wants to do mmio. It calls ioremap_pte_range to map phys addr to a VA. Xen then updates the PV dom0''s L1 with requested io attributes. I''m trying to figure how to do this for PV in HVM container. I was hoping to update the EPT directly. I was thinking of just doing guest_physmap_add_entry() but the mfn is not going to be valid. Is there

These two patches were originally part of the XSM series that I have posted, and remain prerequisites for that series. However, they are independent of the XSM changes and are a useful simplification regardless of the use of XSM. The Acked-bys on these patches were provided before rebasing them over the copyback changes in 26268:1b72138bddda, which had minor conflicts that I resolved. [PATCH

I just built 4.3.0 in order to get > 2GB of RAM in domU with GPU passthrough without crashes. Unfortunately, the same crashes still happen. Massive frame buffer corruption on domU before it locks up solid. It seems the PCI memory stomp is still happening. I am using qemu-dm, as I did on Xen 4.2.x. So whatever fix for this went into 4.3.0 didn''t fix it for me. Passing less than 2GB

*RESEND* due to exceeding the mailinglists limit for attachment size. Hi, I''m trying to get secondary vga-passthrough on a HVM guest to work with a AMD HD6570 and the native kernel radeon driver and kernel modesetting. So the guest still gets the emulated stdvga or cirrus device(used in my case here) as primary/boot vga adapter. - When i don''t passthrough the radeon card, the
