5 daysRevert "drm/amd/display: pause the workload setting in dm"Alex Deucher
This reverts commit bc6d54ac7e7436721a19443265f971f890c13cc5. The workload profile needs to be in the default state when the dc idle optimizaion state is entered. However, when jobs come in for video or GFX or compute, the profile may be set to a non-default profile resulting in the dc idle optimizations not taking affect and resulting in higher power usage. As such we need to pause the workload profile changes during this transition. When this patch was originally committed, it caused a regression with a Dell U3224KB display, but no other problems were reported at the time. When it was reapplied (this patch) to address increased power usage, it seems to have caused additional regressions. This change seems to have a number of side affects (audio issues, stuttering, etc.). I suspect the pause should only happen when all displays are off or in static screen mode, but I think this call site gets called more often than that which results in idle state entry more often than intended. For now revert.

5 daysdrm, drm/xe: Fix xe userptr in the absence of CONFIG_DEVICE_PRIVATEThomas Hellström
CONFIG_DEVICE_PRIVATE is not selected by default by some distros, for example Fedora, and that leads to a regression in the xe driver since userptr support gets compiled out. It turns out that DRM_GPUSVM, which is needed for xe userptr support compiles also without CONFIG_DEVICE_PRIVATE, but doesn't compile without CONFIG_ZONE_DEVICE. Exclude the drm_pagemap files from compilation with !CONFIG_ZONE_DEVICE, and remove the CONFIG_DEVICE_PRIVATE dependency from CONFIG_DRM_GPUSVM and the xe driver's selection of it, re-enabling xe userptr for those configs. v2: - Don't compile the drm_pagemap files unless CONFIG_ZONE_DEVICE is set. - Adjust the drm_pagemap.h header accordingly.

6 daysdrm/amd/pm: Workaround SI powertune issue on Radeon 430 (v2)Timur Kristóf
Radeon 430 and 520 are OEM GPUs from 2016~2017 They have the same device id: 0x6611 and revision: 0x87 On the Radeon 430, powertune is buggy and throttles the GPU, never allowing it to reach its maximum SCLK. Work around this bug by raising the TDP limits we program to the SMC from 24W (specified by the VBIOS on Radeon 430) to 32W. Disabling powertune entirely is not a viable workaround, because it causes the Radeon 520 to heat up above 100 C, which I prefer to avoid. Additionally, revise the maximum SCLK limit. Considering the above issue, these GPUs never reached a high SCLK on Linux, and the workarounds were added before the GPUs were released, so the workaround likely didn't target these specifically. Use 780 MHz (the maximum SCLK according to the VBIOS on the Radeon 430). Note that the Radeon 520 VBIOS has a higher maximum SCLK: 905 MHz, but in practice it doesn't seem to perform better with the higher clock, only heats up more. v2: Move the workaround to si_populate_smc_tdp_limits.

6 daysdrm/xe: Update wedged.mode only after successful reset policy changeLukasz Laguna
Previously, the driver's internal wedged.mode state was updated without verifying whether the corresponding engine reset policy update in GuC succeeded. This could leave the driver reporting a wedged.mode state that doesn't match the actual reset behavior programmed in GuC. With this change, the reset policy is updated first, and the driver's wedged.mode state is modified only if the policy update succeeds on all available GTs. This patch also introduces two functional improvements: - The policy is sent to GuC only when a change is required. An update is needed only when entering or leaving XE_WEDGED_MODE_UPON_ANY_HANG, because only in that case the reset policy changes. For example, switching between XE_WEDGED_MODE_UPON_CRITICAL_ERROR and XE_WEDGED_MODE_NEVER doesn't affect the reset policy, so there is no need to send the same value to GuC. - An inconsistent_reset flag is added to track cases where reset policy update succeeds only on a subset of GTs. If such inconsistency is detected, future wedged mode configuration will force a retry of the reset policy update to restore a consistent state across all GTs.

6 daysdrm/xe/uapi: disallow bind queue sharingMatthew Auld
Currently this is very broken if someone attempts to create a bind queue and share it across multiple VMs. For example currently we assume it is safe to acquire the user VM lock to protect some of the bind queue state, but if allow sharing the bind queue with multiple VMs then this quickly breaks down. To fix this reject using a bind queue with any VM that is not the same VM that was originally passed when creating the bind queue. This a uAPI change, however this was more of an oversight on kernel side that we didn't reject this, and expectation is that userspace shouldn't be using bind queues in this way, so in theory this change should go unnoticed. Based on a patch from Matt Brost. v2 (Matt B): - Hold the vm lock over queue create, to ensure it can't be closed as we attach the user_vm to the queue. - Make sure we actually check for NULL user_vm in destruction path. v3: - Fix error path handling.

Unfortunately, for this driver it wasn't possible to directly use the drm_gem_dma_helper callbacks (apart from .print_info), as the DMA mapping here is done on specific dma devices instead of the main DRM device. Also, since the mtk_gem_obj structure is no more, also migrate the mtk_plane.c code to grab the DMA address from a drm_gem_dma_object and replace the inclusion of the custom mtk_gem.h header (as it is now unneeded) with the DRM API provided drm_gem_dma_helper. While at it, also set DRM_GEM_DMA_HELPER as an unconditional dependency (remove the `if DRM_FBDEV_EMULATION` from the select DRM_GEM_DMA_HELPER statement in Kconfig). This resolves an issue pointed by UBSAN, as when using drm_fbdev_dma the drm_gem_object is supposed to be child of a drm_gem_dma_object instead of a custom mtk_gem_obj (or the mtk_gem_obj should have been reordered to have the same fields as drm_gem_dma_object, but that would have been too fragile and generally a bad idea anyway).

8 daysdrm/mediatek: dpi: Find next bridge during probeChen-Yu Tsai
Trying to find the next bridge and deferring probe in the bridge attach callback is much too late. At this point the driver has already finished probing and is now running the component bind code path. What's even worse is that in the specific case of the DSI host being the last component to be added as part of the dsi_host_attach callback, the code path that this is in: -> devm_drm_of_get_bridge() mtk_dpi_bridge_attach() drm_bridge_attach() mtk_dpi_bind() ... component_add() mtk_dsi_host_attach() anx7625_attach_dsi() anx7625_link_bridge() - done_probing callback for of_dp_aux_populate_bus() of_dp_aux_populate_bus() anx7625_i2c_probe() _cannot_ return probe defer: anx7625 4-0058: [drm:anx7625_bridge_attach] drm attach mediatek-drm mediatek-drm.15.auto: bound 14014000.dsi (ops mtk_dsi_component_ops) mediatek-drm mediatek-drm.15.auto: error -EPROBE_DEFER: failed to attach bridge /soc/dpi@14015000 to encoder TMDS-37 [drm:mtk_dsi_host_attach] *ERROR* failed to add dsi_host component: -517 anx7625 4-0058: [drm:anx7625_link_bridge] *ERROR* fail to attach dsi to host. panel-simple-dp-aux aux-4-0058: DP AUX done_probing() can't defer panel-simple-dp-aux aux-4-0058: probe with driver panel-simple-dp-aux failed with error -22 anx7625 4-0058: [drm:anx7625_i2c_probe] probe done This results in the whole display driver failing to probe. Perhaps this was an attempt to mirror the structure in the DSI driver; but in the DSI driver the next bridge is retrieved in the DSI attach callback, not the bridge attach callback. Move the code finding the next bridge back to the probe function so that deferred probing works correctly. Also rework the fallback to the old OF graph endpoint numbering scheme so that deferred probing logs in both cases. This issue was found on an MT8183 Jacuzzi device with an extra patch enabling the DPI-based external display pipeline. Also tested on an MT8192 Hayato device with both DSI and DPI display pipelines enabled.

13 daysdrm/amdgpu/userq: Fix fence reference leak on queue teardown v2Srinivasan Shanmugam
The user mode queue keeps a pointer to the most recent fence in userq->last_fence. This pointer holds an extra dma_fence reference. When the queue is destroyed, we free the fence driver and its xarray, but we forgot to drop the last_fence reference. Because of the missing dma_fence_put(), the last fence object can stay alive when the driver unloads. This leaves an allocated object in the amdgpu_userq_fence slab cache and triggers This is visible during driver unload as: BUG amdgpu_userq_fence: Objects remaining on __kmem_cache_shutdown() kmem_cache_destroy amdgpu_userq_fence: Slab cache still has objects Call Trace: kmem_cache_destroy amdgpu_userq_fence_slab_fini amdgpu_exit __do_sys_delete_module Fix this by putting userq->last_fence and clearing the pointer during amdgpu_userq_fence_driver_free().

13 daysdrm/amd/display: Initialise backlight level values from hwVivek Das Mohapatra
Internal backlight levels are initialised from ACPI but the values are sometimes out of sync with the levels in effect until there has been a read from hardware (eg triggered by reading from sysfs). This means that the first drm_commit can cause the levels to be set to a different value than the actual starting one, which results in a sudden change in brightness. This path shows the problem (when the values are out of sync): amdgpu_dm_atomic_commit_tail() -> amdgpu_dm_commit_streams() -> amdgpu_dm_backlight_set_level(..., dm->brightness[n]) This patch calls the backlight ops get_brightness explicitly at the end of backlight registration to make sure dm->brightness[n] is in sync with the actual hardware levels.
