Checkpoint BOs last. That way we don't need to close dmabuf FDs if something else fails later. This avoids problematic access to user mode memory in the error handling code path. criu_checkpoint_bos has its own error handling and cleanup that does not depend on access to user memory. In the private data, keep BOs before the remaining objects. This is necessary to restore things in the correct order as restoring events depends on the events-page BO being restored first.

The recent change brought a bug on SRIOV envrionment. It caused unloading amdgpu failed on Guest VM. The reason is that the VF FLR was requested while unloading amdgpu driver, but the VF FLR of SRIOV sequence is wrong while removing PCI device. For SRIOV, the guest driver should not trigger the whole XGMI hive to do the reset. Host driver control how the device been reset.

If a system does not have swap and memory is under 100% usage, amdgpu will fail to evict resources. Currently the suspend carries on proceeding to reset the GPU: ``` [drm] evicting device resources failed [drm:amdgpu_device_ip_suspend_phase2 [amdgpu]] *ERROR* suspend of IP block <vcn_v3_0> failed -12 [drm] free PSP TMR buffer [TTM] Failed allocating page table [drm] evicting device resources failed amdgpu 0000:03:00.0: amdgpu: MODE1 reset amdgpu 0000:03:00.0: amdgpu: GPU mode1 reset amdgpu 0000:03:00.0: amdgpu: GPU smu mode1 reset ``` At this point if the suspend actually succeeded I think that amdgpu would have recovered because the GPU would have power cut off and restored. However the kernel fails to continue the suspend from the memory pressure and amdgpu fails to run the "resume" from the aborted suspend. ``` ACPI: PM: Preparing to enter system sleep state S3 SLUB: Unable to allocate memory on node -1, gfp=0xdc0(GFP_KERNEL|__GFP_ZERO) cache: Acpi-State, object size: 80, buffer size: 80, default order: 0, min order: 0 node 0: slabs: 22, objs: 1122, free: 0 ACPI Error: AE_NO_MEMORY, Could not update object reference count (20210730/utdelete-651) [drm:psp_hw_start [amdgpu]] *ERROR* PSP load kdb failed!

This will let the system gracefully recover and the user can try suspend again when the memory pressure is relieved.

Call intel_sdvo_select_ddc_bus() before initializing any of the outputs. And before that is functional (assuming no VBT) we have to set up the controlled_outputs thing. Otherwise DDC won't be functional during the output init but LVDS really needs it for the fixed mode setup. Note that the whole multi output support still looks very bogus, and more work will be needed to make it correct. But for now this should at least fix the LVDS EDID fixed mode setup.

Robert Beckett authored
swiotlb_max_segment used to return either the maximum size that swiotlb could bounce, or for Xen PV PAGE_SIZE even if swiotlb could bounce buffer larger mappings. This made i915 on Xen PV work as it bypasses the coherency aspect of the DMA API and can't cope with bounce buffering and this avoided bounce buffering for the Xen/PV case. So instead of adding this hack back, check for Xen/PV directly in i915 for the Xen case and otherwise use the proper DMA API helper to query the maximum mapping size. Replace swiotlb_max_segment() calls with dma_max_mapping_size(). In i915_gem_object_get_pages_internal() no longer consider max_segment only if CONFIG_SWIOTLB is enabled. There can be other (iommu related) causes of specific max segment sizes.

Imre Deak authored
Accessing the TypeC DKL PHY registers during modeset-commit, -verification, DP link-retraining and AUX power well toggling is racy due to these code paths being concurrent and the PHY register bank selection register (HIP_INDEX_REG) being shared between PHY instances (aka TC ports) and the bank selection being not atomic wrt. the actual PHY register access. Add the required locking around each PHY register bank selection-> register access sequence. Kudos to Ville for noticing the race conditions. v2: - Add the DKL PHY register accessors to intel_dkl_phy.[ch]. (Jani) - Make the DKL_REG_TC_PORT macro independent of PHY internals. - Move initing the DKL PHY lock to a more logical place. v3: - Fix parameter reuse in the DKL_REG_TC_PORT definition. - Document the usage of phy_lock. v4: - Fix adding TC_PORT_1 offset in the DKL_REG_TC_PORT definition.

Hector Martin authored
drm_fb_build_fourcc_list() currently returns all emulated formats unconditionally as long as the native format is among them, even though not all combinations have conversion helpers. Although the list is arguably provided to userspace in precedence order, userspace can pick something out-of-order (and thus break when it shouldn't), or simply only support a format that is unsupported (and thus think it can work, which results in the appearance of a hang as FB blits fail later on, instead of the initialization error you'd expect in this case). Add checks to filter the list of emulated formats to only those supported for conversion to the native format. This presumes that there is a single native format (only the first is checked, if there are multiple). Refactoring this API to drop the native list or support it properly (by returning the appropriate emulated->native mapping table) is left for a future patch. The simpledrm driver is left as-is with a full table of emulated formats. This keeps all currently working conversions available and drops all the broken ones (i.e. this a strict bugfix patch, adding no new supported formats nor removing any actually working ones). In order to avoid proliferation of emulated formats, future drivers should advertise only XRGB8888 as the sole emulated format (since some userspace assumes its presence). This fixes a real user regression where the ?RGB2101010 support commit started advertising it unconditionally where not supported, and KWin decided to start to use it over the native format and broke, but also the fixes the spurious RGB565/RGB888 formats which have been wrongly unconditionally advertised since the dawn of simpledrm.
