Pull drm fixes from Dave Airlie: "Regular weekly pull request, from sunny San Diego. Usual suspects in xe/i915/amdgpu with small fixes all over, then some minor fixes across a few other drivers. It's probably a bit on the heavy side, but most of the fix seem well contained, core: - drm_dev_unplug UAF fix pagemap: - lock handling fix xe: - A number of teardown fixes - Skip over non-leaf PTE for PRL generation - Fix an uninitialized variable - Fix a missing runtime PM reference i915/display: - Fix #15771: Screen corruption and stuttering on P14s w/ 3K display - Fix for PSR entry setup frames count on rejected commit - Fix OOPS if firmware is not loaded and suspend is attempted - Fix unlikely NULL deref due to DC6 on probe amdgpu: - Fix gamma 2.2 colorop TFs - BO list fix - LTO fix - DC FP fix - DisplayID handling fix - DCN 2.01 fix - MMHUB boundary fixes - ISP fix - TLB fence fix - Hainan pm fix radeon: - Hainan pm fix vmwgfx: - memory leak fix - doc warning fix imagination: - deadlock fix - interrupt handling fixes dw-hdmi-qp: - multi channel audio fix" * tag 'drm-fixes-2026-03-21' of https://gitlab.freedesktop.org/drm/kernel: (40 commits) drm/xe: Fix missing runtime PM reference in ccs_mode_store drm/xe: Open-code GGTT MMIO access protection drm/xe/lrc: Fix uninitialized new_ts when capturing context timestamp drm/xe/oa: Allow reading after disabling OA stream drm/xe: Skip over non leaf pte for PRL generation drm/xe/guc: Ensure CT state transitions via STOP before DISABLED drm/xe: Trigger queue cleanup if not in wedged mode 2 drm/xe: Forcefully tear down exec queues in GuC submit fini drm/xe: Always kill exec queues in xe_guc_submit_pause_abort drm/xe/guc: Fail immediately on GuC load error drm/i915/gt: Check set_default_submission() before deferencing drm/radeon: apply state adjust rules to some additional HAINAN vairants drm/amdgpu: apply state adjust rules to some additional HAINAN vairants drm/amdgpu: rework how we handle TLB fences drm/bridge: dw-hdmi-qp: fix multi-channel audio output drm: Fix use-after-free on framebuffers and property blobs when calling drm_dev_unplug drm/amdgpu: Fix ISP segfault issue in kernel v7.0 drm/amdgpu/gmc9.0: add bounds checking for cid drm/amdgpu/mmhub4.2.0: add bounds checking for cid drm/amdgpu/mmhub4.1.0: add bounds checking for cid ...

d>Suravee Suthikulpanit invalidation Each nested domain is assigned guest domain ID (gDomID), which guest OS programs into guest Device Table Entry (gDTE). For each gDomID, the driver assigns a corresponding host domain ID (hDomID), which will be programmed into the host Device Table Entry (hDTE). The hDomID is allocated during amd_iommu_alloc_domain_nested(), and free during nested_domain_free(). The gDomID-to-hDomID mapping info (struct guest_domain_mapping_info) is stored in a per-viommu xarray (struct amd_iommu_viommu.gdomid_array), which is indexed by gDomID. Note also that parent domain can be shared among struct iommufd_viommu. Therefore, when hypervisor invalidates the nest parent domain, the AMD IOMMU command INVALIDATE_IOMMU_PAGES must be issued for each hDomID in the gdomid_array. This is handled by the iommu_flush_pages_v1_hdom_ids(), where it iterates through struct protection_domain.viommu_list.

Information in the nest parent is needed when setting up the nested translation. Note that the viommu initialization will be introduced in subsequent commit.

The IOMMU driver checks each feature-specific bits before enabling each feature at run time. For IOMMUFD, the hypervisor passes the raw value of amd_iommu_efr and amd_iommu_efr2 to VMM via iommufd IOMMU_DEVICE_GET_HW_INFO ioctl.
