2022-09-13drm/amd/display: Enable dlg and vba compilation for dcn314Rodrigo Siqueira1-0/+3
We were not using the VBA and DLG files for DCN314, but the next sequence of changes for DCN314 will require those files. This commit adds the necessary files to the Makefile.

2022-09-11iommu: Fix false ownership failure on AMD systems with PASID activatedJason Gunthorpe2-2/+21
The AMD IOMMU driver cannot activate PASID mode on a RID without the RID's translation being set to IDENTITY. Further it requires changing the RID's page table layout from the normal v1 IOMMU_DOMAIN_IDENTITY layout to a different v2 layout. It does this by creating a new iommu_domain, configuring that domain for v2 identity operation and then attaching it to the group, from within the driver. This logic assumes the group is already set to the IDENTITY domain and is being used by the DMA API. However, since the ownership logic is based on the group's domain pointer equaling the default domain to detect DMA API ownership, this causes it to look like the group is not attached to the DMA API any more. This blocks attaching drivers to any other devices in the group. In a real system this manifests itself as the HD-audio devices on some AMD platforms losing their device drivers. Work around this unique behavior of the AMD driver by checking for equality of IDENTITY domains based on their type, not their pointer value. This allows the AMD driver to have two IDENTITY domains for internal purposes without breaking the check. Have the AMD driver properly declare that the special domain it created is actually an IDENTITY domain.

2022-09-11iommu/vt-d: Fix possible recursive locking in intel_iommu_init()Lu Baolu3-26/+12
The global rwsem dmar_global_lock was introduced by commit 3a5670e8ac932 ("iommu/vt-d: Introduce a rwsem to protect global data structures"). It is used to protect DMAR related global data from DMAR hotplug operations. The dmar_global_lock used in the intel_iommu_init() might cause recursive locking issue, for example, intel_iommu_get_resv_regions() is taking the dmar_global_lock from within a section where intel_iommu_init() already holds it via probe_acpi_namespace_devices(). Using dmar_global_lock in intel_iommu_init() could be relaxed since it is unlikely that any IO board must be hot added before the IOMMU subsystem is initialized. This eliminates the possible recursive locking issue by moving down DMAR hotplug support after the IOMMU is initialized and removing the uses of dmar_global_lock in intel_iommu_init().

2022-09-10arm64: mm: fix resume for 52-bit enabled buildsJoey Gouly1-0/+3
__cpu_setup() was changed to take the actual number of VA bits in x0, however the resume path was not updated at the same time. Load `vabits_actual` in the resume path, to ensure that the correct number of VA bits is used. This fixes booting v6.0-rc kernels on my Juno.

2022-09-10mksysmap: Fix the mismatch of 'L0' symbols in System.mapYouling Tang1-1/+1
When System.map was generated, the kernel used mksysmap to filter the kernel symbols, we need to filter "L0" symbols in LoongArch architecture. $ cat System.map | grep L0 9000000000221540 t L0 The L0 symbol exists in System.map, but not in .tmp_System.map. When "cmp -s System.map .tmp_System.map" will show "Inconsistent kallsyms data" error message in link-vmlinux.sh script.

Included in here are: - multiple attempts to get the arch_topology code to work properly on non-cluster SMT systems. First attempt caused build breakages in linux-next and 0-day, second try worked. - debugfs fixes for a long-suffering memory leak. The pattern of debugfs_remove(debugfs_lookup(...)) turns out to leak dentries, so add debugfs_lookup_and_remove() to fix this problem. Also fix up the scheduler debug code that highlighted this problem. Fixes for other subsystems will be trickling in over the next few months for this same issue once the debugfs function is merged.
