intel_iommu: scalable mode emulation Intel(R) VT-d 3.0 spec introduces scalable mode address translation to replace extended context mode. This patch extends current emulator to support Scalable Mode which includes root table, context table and new pasid table format change. Now intel_iommu emulates both legacy mode and scalable mode (with legacy-equivalent capability set). The key points are below: 1. Extend root table operations to support both legacy mode and scalable mode. 2. Extend context table operations to support both legacy mode and scalable mode. 3. Add pasid tabled operations to support scalable mode.

intel-iommu: trace domain id during page walk This patch only modifies the trace points. Previously we were tracing page walk levels. They are redundant since we have page mask (size) already. Now we trace something much more useful which is the domain ID of the page walking. That can be very useful when we trace more than one devices on the same system, so that we can know which map is for which domain.

intel-iommu: rework the page walk logic This patch fixes a potential small window that the DMA page table might be incomplete or invalid when the guest sends domain/context invalidations to a device. This can cause random DMA errors for assigned devices. This is a major change to the VT-d shadow page walking logic. It includes but is not limited to: - For each VTDAddressSpace, now we maintain what IOVA ranges we have mapped and what we have not. With that information, now we only send MAP or UNMAP when necessary. Say, we don't send MAP notifies if we know we have already mapped the range, meanwhile we don't send UNMAP notifies if we know we never mapped the range at all. - Introduce vtd_sync_shadow_page_table[_range] APIs so that we can call in any places to resync the shadow page table for a device. - When we receive domain/context invalidation, we should not really run the replay logic, instead we use the new sync shadow page table API to resync the whole shadow page table without unmapping the whole region. After this change, we'll only do the page walk once for each domain invalidations (before this, it can be multiple, depending on number of notifiers per address space). While at it, the page walking logic is also refactored to be simpler.

intel_iommu: allow dynamic switch of IOMMU region This is preparation work to finally enabled dynamic switching ON/OFF for VT-d protection. The old VT-d codes is using static IOMMU address space, and that won't satisfy vfio-pci device listeners. Let me explain. vfio-pci devices depend on the memory region listener and IOMMU replay mechanism to make sure the device mapping is coherent with the guest even if there are domain switches. And there are two kinds of domain switches: (1) switch from domain A -> B (2) switch from domain A -> no domain (e.g., turn DMAR off) Case (1) is handled by the context entry invalidation handling by the VT-d replay logic. What the replay function should do here is to replay the existing page mappings in domain B. However for case (2), we don't want to replay any domain mappings - we just need the default GPA->HPA mappings (the address_space_memory mapping). And this patch helps on case (2) to build up the mapping automatically by leveraging the vfio-pci memory listeners. Another important thing that this patch does is to seperate IR (Interrupt Remapping) from DMAR (DMA Remapping). IR region should not depend on the DMAR region (like before this patch). It should be a standalone region, and it should be able to be activated without DMAR (which is a common behavior of Linux kernel - by default it enables IR while disabled DMAR).

intel_iommu: enable remote IOTLB This patch is based on Aviv Ben-David (<bd.aviv@gmail.com>)'s patch upstream: "IOMMU: enable intel_iommu map and unmap notifiers" https://lists.gnu.org/archive/html/qemu-devel/2016-11/msg01453.html However I removed/fixed some content, and added my own codes. Instead of translate() every page for iotlb invalidations (which is slower), we walk the pages when needed and notify in a hook function. This patch enables vfio devices for VT-d emulation. And, since we already have vhost DMAR support via device-iotlb, a natural benefit that this patch brings is that vt-d enabled vhost can live even without ATS capability now. Though more tests are needed.

intel_iommu: relax iq tail check on VTD_GCMD_QIE enable The VT-d spec (section 6.5.2) prescribes software to zero the Invalidation Queue Tail Register before enabling the VTD_GCMD_QIE Global Command Register bit. Windows Server 2012 R2 and possibly other older Windows versions violate the protocol and set a non-zero queue tail first, which in effect makes them crash early on boot with -device intel-iommu,intremap=on. This commit relaxes the check and instead of failing to enable VTD_GCMD_QIE with vtd_err_qi_enable, it behaves as if the tail register was set just after enabling VTD_GCMD_QIE (see vtd_handle_iqt_write).

intel_iommu: switching the rest DPRINTF to trace We have converted many of the DPRINTF() into traces. This patch does the last 100+ ones. To debug VT-d when error happens, let's try enable: -trace enable="vtd_err*" This should works just like the old GENERAL but of course better, since we don't need to recompile. Similar rules apply to the other modules. I was trying to make the prefix good enough for sub-module debugging. Signed-off-by: Peter Xu <peterx@redhat.com> Reviewed-by: Michael S.

intel_iommu: convert dbg macros to traces for inv VT-d codes are still using static DEBUG_INTEL_IOMMU macro. That's not good, and we should end the day when we need to recompile the code before getting useful debugging information for vt-d. Time to switch to the trace system. This is the first patch to do it.

trace: Avoid abuse of amdvi_mmio_read hw/i386/trace-events has an amdvi_mmio_read trace that is used for both normal reads (listing the register name, address, size, and offset) and for an error case (abusing the register name to show an error message, the address to show the maximum value supported, then shoehorning address and size into the size and offset parameters). The change from a wide address to a narrower size parameter could truncate a (rather-large) bogus read attempt, so it's better to create a separate dedicated trace with correct types, rather than abusing the trace mechanism. Broken since its introduction in commit d29a09c. [Change trace event argument type from hwaddr to uint64_t since user-defined types should not be used for trace events.
