2022-09-14drm/amdgpu: make sure to init common IP before gmcAlex Deucher
Move common IP init before GMC init so that HDP gets remapped before GMC init which uses it. This fixes the Unsupported Request error reported through AER during driver load. The error happens as a write happens to the remap offset before real remapping is done. Link: https://bugzilla.kernel.org/show_bug.cgi?id=216373 The error was unnoticed before and got visible because of the commit referenced below. This doesn't fix anything in the commit below, rather fixes the issue in amdgpu exposed by the commit. The reference is only to associate this commit with below one so that both go together.

2022-09-14drm/amdgpu: move nbio sdma_doorbell_range() into sdma code for vegaAlex Deucher
This mirrors what we do for other asics and this way we are sure the sdma doorbell range is properly initialized. There is a comment about the way doorbells on gfx9 work that requires that they are initialized for other IPs before GFX is initialized. However, the statement says that it applies to multimedia as well, but the VCN code currently initializes doorbells after GFX and there are no known issues there. In my testing at least I don't see any problems on SDMA. This is a prerequisite for fixing the Unsupported Request error reported through AER during driver load.

2022-09-14drm/rockchip: Fix return type of cdn_dp_connector_mode_validNathan Huckleberry
The mode_valid field in drm_connector_helper_funcs is expected to be of type: enum drm_mode_status (* mode_valid) (struct drm_connector *connector, struct drm_display_mode *mode); The mismatched return type breaks forward edge kCFI since the underlying function definition does not match the function hook definition. The return type of cdn_dp_connector_mode_valid should be changed from int to enum drm_mode_status.

2022-09-13drm/amd/display: Mark dml30's UseMinimumDCFCLK() as noinline for stack usageNathan Chancellor
This function consumes a lot of stack space and it blows up the size of dml30_ModeSupportAndSystemConfigurationFull() with clang: drivers/gpu/drm/amd/amdgpu/../display/dc/dml/dcn30/display_mode_vba_30.c:3542:6: error: stack frame size (2200) exceeds limit (2048) in 'dml30_ModeSupportAndSystemConfigurationFull' [-Werror,-Wframe-larger-than] void dml30_ModeSupportAndSystemConfigurationFull(struct display_mode_lib *mode_lib) ^ 1 error generated. Commit a0f7e7f759cf ("drm/amd/display: fix i386 frame size warning") aimed to address this for i386 but it did not help x86_64. To reduce the amount of stack space that dml30_ModeSupportAndSystemConfigurationFull() uses, mark UseMinimumDCFCLK() as noinline, using the _for_stack variant for documentation. While this will increase the total amount of stack usage between the two functions (1632 and 1304 bytes respectively), it will make sure both stay below the limit of 2048 bytes for these files. The aforementioned change does help reduce UseMinimumDCFCLK()'s stack usage so it should not be reverted in favor of this change.

2022-09-11iommu: Fix false ownership failure on AMD systems with PASID activatedJason Gunthorpe
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 Baolu
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().
