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.

2022-11-02drm/amd: Fail the suspend if resources can't be evictedMario Limonciello1-5/+10
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.

2022-10-31drm/i915: stop abusing swiotlb_max_segmentRobert Beckett5-32/+29
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.

2022-10-31drm/i915/tgl+: Add locking around DKL PHY register accessesImre Deak9-76/+204
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.

2022-10-31drm/format-helper: Only advertise supported formats for conversionHector Martin1-19/+47
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.

2022-10-29drm/rockchip: vop2: disable planes when disabling the crtcMichael Tretter1-0/+4
The vop2 driver needs to explicitly disable the planes if the crtc is disabled. Unless the planes are explicitly disabled, the address of the last framebuffer is kept in the registers of the VOP2. When re-enabling the encoder after it has been disabled by the driver, the VOP2 will start and read the framebuffer that has been freed but is still pointed to by the register. The iommu will catch these read accesses and print errors. Explicitly disable the planes when the crtc is disabled to reset the registers.

2022-10-29drm/rockchip: vop2: fix null pointer in plane_atomic_disableMichael Tretter1-2/+4
If the vop2_plane_atomic_disable function is called with NULL as a state, accessing the old_pstate runs into a null pointer exception. However, the drm_atomic_helper_disable_planes_on_crtc function calls the atomic_disable callback with state NULL. Allow to disable a plane without passing a plane state by checking the old_pstate only if a state is passed.

2022-10-29drm/rockchip: fix fbdev on non-IOMMU devicesJohn Keeping1-1/+4
When switching to the generic fbdev infrastructure, it was missed that framebuffers were created with the alloc_kmap parameter to rockchip_gem_create_object() set to true. The generic infrastructure calls this via the .dumb_create() driver operation and thus creates a buffer without an associated kmap. alloc_kmap only makes a difference on devices without an IOMMU, but when it is missing rockchip_gem_prime_vmap() fails and the framebuffer cannot be used. Detect the case where a buffer is being allocated for the framebuffer and ensure a kernel mapping is created in this case.

2022-10-29drm/rockchip: dsi: Force synchronous probeBrian Norris1-0/+6
We can't safely probe a dual-DSI display asynchronously (driver_async_probe='*' or driver_async_probe='dw-mipi-dsi-rockchip' cmdline), because dw_mipi_dsi_rockchip_find_second() pokes one DSI device's drvdata from the other device without any locking. Request synchronous probe, at least until this driver learns some appropriate locking for dual-DSI initialization.

2022-10-29drm/rockchip: dsi: Clean up 'usage_mode' when failing to attachBrian Norris1-4/+12
If we fail to attach the first time (especially: EPROBE_DEFER), we fail to clean up 'usage_mode', and thus will fail to attach on any subsequent attempts, with "dsi controller already in use". Re-set to DW_DSI_USAGE_IDLE on attach failure. This is especially common to hit when enabling asynchronous probe on a duel-DSI system (such as RK3399 Gru/Scarlet), such that we're more likely to fail dw_mipi_dsi_rockchip_find_second() the first time.
