2023-01-05drm/fourcc: Document open source user waiverDaniel Vetter
It's a bit a FAQ, and we really can't claim to be the authoritative source for allocating these numbers used in many standard extensions if we tell closed source or vendor stacks in general to go away. Iirc this was already clarified in some vulkan discussions, but I can't find that anywhere anymore. At least not in a public link.

2022-11-09drm/amdgpu: Set MTYPE in PTE based on BO flagsFelix Kuehling
The same BO may need different MTYPEs and SNOOP flags in PTEs depending on its current location relative to the mapping GPU. Setting MTYPEs from clients ahead of time is not practical for coherent memory sharing. Instead determine the correct MTYPE for the desired coherence model and current BO location when updating the page tables. To maintain backwards compatibility with MTYPE-selection in AMDGPU_VA_OP_MAP, the coherence-model-based MTYPE selection is only applied if it chooses an MTYPE other than MTYPE_NC (the default). Add two AMDGPU_GEM_CREATE_... flags to indicate the coherence model. The default if no flag is specified is non-coherent (i.e. coarse-grained coherent at dispatch boundaries). Update amdgpu_amdkfd_gpuvm.c to use this new method to choose the correct MTYPE depending on the current memory location. v2: * check that bo is not NULL (e.g. PRT mappings) * Fix missing ~ bitmask in gmc_v11_0.c v3: * squash in "drm/amdgpu: Inherit coherence flags on dmabuf import" Suggested-by: Christian König <christian.koenig@amd.com> Signed-off-by: Felix Kuehling <Felix.Kuehling@amd.com> Acked-by: Christian König <christian.koenig@amd.com> Signed-off-by: Alex Deucher <alexander.deucher@amd.com>

2022-11-07drm/panfrost: Remove type name from internal struct againSteven Price

2022-10-27drm/i915/perf: Apply Wa_18013179988Umesh Nerlige Ramappa
OA reports in the OA buffer contain an OA timestamp field that helps user calculate delta between 2 OA reports. The calculation relies on the CS timestamp frequency to convert the timestamp value to nanoseconds. The CS timestamp frequency is a function of the CTC_SHIFT value in RPM_CONFIG0. In DG2, OA unit assumes that the CTC_SHIFT is 3, instead of using the actual value from RPM_CONFIG0. At the user level, this results in an error in calculating delta between 2 OA reports since the OA timestamp is not shifted in the same manner as CS timestamp. Also the periodicity of the reports is different from what the user configured because of mismatch in the CS and OA frequencies. The issue also affects MI_REPORT_PERF_COUNT command. To resolve this, return actual OA timestamp frequency to the user in i915_getparam_ioctl, so that user can calculate the right OA exponent as well as interpret the reports correctly.

__le32 and __le64 types aren't portable and are not available on FreeBSD (which uses the same uAPI). Instead of attempting to always output little endian, just use native endianness in the dumps.

2022-10-19dmaengine: idxd: Do not enable user type Work Queue without Shared Virtual ↵Fenghua Yu
Addressing When the idxd_user_drv driver is bound to a Work Queue (WQ) device without IOMMU or with IOMMU Passthrough without Shared Virtual Addressing (SVA), the application gains direct access to physical memory via the device by programming physical address to a submitted descriptor. This allows direct userspace read and write access to arbitrary physical memory. This is inconsistent with the security goals of a good kernel API. Unlike vfio_pci driver, the IDXD char device driver does not provide any ways to pin user pages and translate the address from user VA to IOVA or PA without IOMMU SVA. Therefore the application has no way to instruct the device to perform DMA function. This makes the char device not usable for normal application usage. Since user type WQ without SVA cannot be used for normal application usage and presents the security issue, bind idxd_user_drv driver and enable user type WQ only when SVA is enabled (i.e. user PASID is enabled).

2022-10-14drm/i915: enable PS64 support for DG2Matthew Auld
It turns out that on production DG2/ATS HW we should have support for PS64. This feature allows to provide a 64K TLB hint at the PTE level, which is a lot more flexible than the current method of enabling 64K GTT pages for the entire page-table, since that leads to all kinds of annoying restrictions, as documented in: commit caa574ffc4aaf4f29b890223878c63e2e7772f62 Author: Matthew Auld <matthew.auld@intel.com> Date: Sat Feb 19 00:17:49 2022 +0530 drm/i915/uapi: document behaviour for DG2 64K support On discrete platforms like DG2, we need to support a minimum page size of 64K when dealing with device local-memory. This is quite tricky for various reasons, so try to document the new implicit uapi for this. With PS64, we can now drop the 2M GTT alignment restriction, and instead only require 64K or larger when dealing with lmem. We still use the compact-pt layout when possible, but only when we are certain that this doesn't interfere with userspace. Note that this is a change in uAPI behaviour, but hopefully shouldn't be a concern (IGT is at least able to autodetect the alignment), since we are only making the GTT alignment constraint less restrictive. Based on a patch from CQ Tang. v2: update the comment wrt scratch page v3: (Nirmoy) - Fix the selftest to actually use the random size, plus some comment improvements, also drop the rem stuff.

Pull VFIO updates from Alex Williamson: - Prune private items from vfio_pci_core.h to a new internal header, fix missed function rename, and refactor vfio-pci interrupt defines (Jason Gunthorpe) - Create consistent naming and handling of ioctls with a function per ioctl for vfio-pci and vfio group handling, use proper type args where available (Jason Gunthorpe) - Implement a set of low power device feature ioctls allowing userspace to make use of power states such as D3cold where supported (Abhishek Sahu) - Remove device counter on vfio groups, which had restricted the page pinning interface to singleton groups to account for limitations in the type1 IOMMU backend. Document usage as limited to emulated IOMMU devices, ie. traditional mdev devices where this restriction is consistent (Jason Gunthorpe) - Correct function prefix in hisi_acc driver incurred during previous refactoring (Shameer Kolothum) - Correct typo and remove redundant warning triggers in vfio-fsl driver (Christophe JAILLET) - Introduce device level DMA dirty tracking uAPI and implementation in the mlx5 variant driver (Yishai Hadas & Joao Martins) - Move much of the vfio_device life cycle management into vfio core, simplifying and avoiding duplication across drivers. This also facilitates adding a struct device to vfio_device which begins the introduction of device rather than group level user support and fills a gap allowing userspace identify devices as vfio capable without implicit knowledge of the driver (Kevin Tian & Yi Liu) - Split vfio container handling to a separate file, creating a more well defined API between the core and container code, masking IOMMU backend implementation from the core, allowing for an easier future transition to an iommufd based implementation of the same (Jason Gunthorpe) - Attempt to resolve race accessing the iommu_group for a device between vfio releasing DMA ownership and removal of the device from the IOMMU driver. Follow-up with support to allow vfio_group to exist with NULL iommu_group pointer to support existing userspace use cases of holding the group file open (Jason Gunthorpe) - Fix error code and hi/lo register manipulation issues in the hisi_acc variant driver, along with various code cleanups (Longfang Liu) - Fix a prior regression in GVT-g group teardown, resulting in unreleased resources (Jason Gunthorpe) - A significant cleanup and simplification of the mdev interface, consolidating much of the open coded per driver sysfs interface support into the mdev core (Christoph Hellwig) - Simplification of tracking and locking around vfio_groups that fall out from previous refactoring (Jason Gunthorpe) - Replace trivial open coded f_ops tests with new helper (Alex Williamson) * tag 'vfio-v6.1-rc1' of https://github.com/awilliam/linux-vfio: (77 commits) vfio: More vfio_file_is_group() use cases vfio: Make the group FD disassociate from the iommu_group vfio: Hold a reference to the iommu_group in kvm for SPAPR vfio: Add vfio_file_is_group() vfio: Change vfio_group->group_rwsem to a mutex vfio: Remove the vfio_group->users and users_comp vfio/mdev: add mdev available instance checking to the core vfio/mdev: consolidate all the description sysfs into the core code vfio/mdev: consolidate all the available_instance sysfs into the core code vfio/mdev: consolidate all the name sysfs into the core code vfio/mdev: consolidate all the device_api sysfs into the core code vfio/mdev: remove mtype_get_parent_dev vfio/mdev: remove mdev_parent_dev vfio/mdev: unexport mdev_bus_type vfio/mdev: remove mdev_from_dev vfio/mdev: simplify mdev_type handling vfio/mdev: embedd struct mdev_parent in the parent data structure vfio/mdev: make mdev.h standalone includable drm/i915/gvt: simplify vgpu configuration management drm/i915/gvt: fix a memory leak in intel_gvt_init_vgpu_types ...
