2026-01-19drm/imagination: Validate fw trace group_maskMatt Coster
This value can come from two places: a module parameter or a debugfs file.

2026-01-19drm/display: hdmi_state_helper: split InfoFrame functions per typeDmitry Baryshkov
Havign a single set of InfoFrame callbacks doesn't provide enough information to the DRM framework about the InfoFrame types that are actually supported. Also it's not really future-proof: it provides a way to program only a single Vendor-Specific frame, however we might need to support multiple VSIs at the same time (e.g. HDMI vs HDMI Forum VSIs). Provide separate sets of callbacks, one per the InfoFrame type.

2026-01-19drm/bridge: refactor HDMI InfoFrame callbacksDmitry Baryshkov
Having only a single set of callbacks, hdmi_clear_infoframe and hdmi_write_infoframe, bridge drivers don't have an easy way to signal to the DRM framework, which InfoFrames are actually supported by the hardware and by the driver and which are not. Also, it makes it extremely easy for HDMI bridge drivers to skip implementing the seemingly required InfoFrames (e.g. HDMI VSI). Last, but not least, those callbacks take a single 'type' parameter, which makes it impossible to implement support for multiple VSIs (which will be required once we start working on HDMI Forum VSI). Split the callbacks into a per-InfoFrame-kind pairs, letting the bridge drivers actually signal supported features. The implementation follows the overall drm_bridge design, where the bridge has a single drm_bridge_funcs implementation and signals, which functions are to be called using the drm_bridge->ops flags. The AVI and HDMI VSI are assumed to be required for a normal HDMI operation (with the drivers getting a drm_warn_once() stub implementation if one is missing). The Audio InfoFrame is handled by the existing DRM_BRIDGE_OP_HDMI_AUDIO, while the SPD and HDR DRM InfoFrames got new drm_bridge_ops values.

With some panels informing support for Panel Replay we are observing problems if having Panel Replay enable bit set on sink when forced to use PSR instead of Panel Replay.

2026-01-18drm/mediatek: mtk_gem: Partial refactor and use drm_gem_dma_objectAngeloGioacchino Del Regno
Partially refactor mtk_gem to stop using (and remove) the unneeded custom mtk_gem_obj structure and migrate drivers to use the API defined drm_gem_dma_object structure instead, and to align all of the functions to be similar to the logic from drm_gem_dma_helper. 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).

2026-01-18drm/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.

2026-01-18drm/msm: Replace custom dumb_map_offset with generic helperSwaraj Gaikwad
The msm driver implements a custom dumb_map_offset callback. This implementation acquires the msm_gem_lock, but the underlying drm_gem_create_mmap_offset() function is already thread-safe regarding the VMA offset manager (it acquires the mgr->vm_lock internally). Switching to the generic drm_gem_dumb_map_offset() helper provides several benefits: 1. Removes the unnecessary locking overhead (locking leftovers). 2. Adds a missing check to reject mapping of imported objects, which is invalid for dumb buffers. 3. Allows for the removal of the msm_gem_dumb_map_offset() wrapper and the msm_gem_mmap_offset() helper function. The logic from msm_gem_mmap_offset() has been inlined into msm_ioctl_gem_info() to maintain functionality without the separate helper.

2026-01-16drm/mediatek: mtk_dsi: Add support for High Speed (HS) modeAngeloGioacchino Del Regno
Up until now, the MediaTek DSI Controller has always been working in Low Power Mode (LPM), as this driver has always ignored the MIPI_DSI_MSG_USE_LPM flag hence never setting HS mode. In the current state of the driver the only thing that is needed to add support for DSI High Speed (HS) transmit is to simply set the "HSTX" config bit in the configuration register. Check if flag MIPI_DSI_MSG_USE_LPM is set and, if not, set HSTX.

2026-01-16drm: Discard pm_runtime_put() return valueRafael J. Wysocki
Multiple DRM drivers use the pm_runtime_put() return value for printing debug or even error messages and all of those messages are at least somewhat misleading. Returning an error code from pm_runtime_put() merely means that it has not queued up a work item to check whether or not the device can be suspended and there are many perfectly valid situations in which that can happen, like after writing "on" to the devices' runtime PM "control" attribute in sysfs for one example. It also happens when the kernel has been configured with CONFIG_PM unset. For this reason, modify all of those drivers to simply discard the pm_runtime_put() return value which is what they should be doing. This will facilitate a planned change of the pm_runtime_put() return type to void in the future. Signed-off-by: Rafael J.

2026-01-16drm: Account property blob allocations to memcgXiao Kan
DRM_IOCTL_MODE_CREATEPROPBLOB allows userspace to allocate arbitrary-sized property blobs backed by kernel memory. Currently, the blob data allocation is not accounted to the allocating process's memory cgroup, allowing unprivileged users to trigger unbounded kernel memory consumption and potentially cause system-wide OOM. Mark the property blob data allocation with GFP_KERNEL_ACCOUNT so that the memory is properly charged to the caller's memcg. This ensures existing cgroup memory limits apply and prevents uncontrolled kernel memory growth without introducing additional policy or per-file limits.

2026-01-16drm: renesas: rz-du: mipi_dsi: fix kernel panic when rebooting for some panelsHugo Villeneuve
Since commit 56de5e305d4b ("clk: renesas: r9a07g044: Add MSTOP for RZ/G2L") we may get the following kernel panic, for some panels, when rebooting: systemd-shutdown[1]: Rebooting. Call trace: ... do_serror+0x28/0x68 el1h_64_error_handler+0x34/0x50 el1h_64_error+0x6c/0x70 rzg2l_mipi_dsi_host_transfer+0x114/0x458 (P) mipi_dsi_device_transfer+0x44/0x58 mipi_dsi_dcs_set_display_off_multi+0x9c/0xc4 ili9881c_unprepare+0x38/0x88 drm_panel_unprepare+0xbc/0x108 This happens for panels that need to send MIPI-DSI commands in their unprepare() callback. Since the MIPI-DSI interface is stopped at that point, rzg2l_mipi_dsi_host_transfer() triggers the kernel panic. Fix by moving rzg2l_mipi_dsi_stop() to new callback function rzg2l_mipi_dsi_atomic_post_disable(). With this change we now have the correct power-down/stop sequence: systemd-shutdown[1]: Rebooting. rzg2l-mipi-dsi 10850000.dsi: rzg2l_mipi_dsi_atomic_disable(): entry ili9881c-dsi 10850000.dsi.0: ili9881c_unprepare(): entry rzg2l-mipi-dsi 10850000.dsi: rzg2l_mipi_dsi_atomic_post_disable(): entry reboot: Restarting system Suggested-by: Biju Das <biju.das.jz@bp.renesas.com> Signed-off-by: Hugo Villeneuve <hvilleneuve@dimonoff.com> Tested-by: Biju Das <biju.das.jz@bp.renesas.com> Link: https://patch.msgid.link/20260112154333.655352-1-hugo@hugovil.com Signed-off-by: Biju Das <biju.das.jz@bp.renesas.com>

2026-01-15drm/msm/a6xx: fix bogus hwcg register updatesJohan Hovold
The hw clock gating register sequence consists of register value pairs that are written to the GPU during initialisation. The a690 hwcg sequence has two GMU registers in it that used to amount to random writes in the GPU mapping, but since commit 188db3d7fe66 ("drm/msm/a6xx: Rebase GMU register offsets") they trigger a fault as the updated offsets now lie outside the mapping. This in turn breaks boot of machines like the Lenovo ThinkPad X13s. Note that the updates of these GMU registers is already taken care of properly since commit 40c297eb245b ("drm/msm/a6xx: Set GMU CGC properties on a6xx too"), but for some reason these two entries were left in the table.

2026-01-15drm/xe: Cleanup unused header includesMatt Roper
clangd reports many "unused header" warnings throughout the Xe driver. Start working to clean this up by removing unnecessary includes in our .c files and/or replacing them with explicit includes of other headers that were previously being included indirectly. By far the most common offender here was unnecessary inclusion of xe_gt.h. That likely originates from the early days of xe.ko when xe_mmio did not exist and all register accesses, including those unrelated to GTs, were done with GT functions. There's still a lot of additional #include cleanup that can be done in the headers themselves; that will come as a followup series. v2: - Squash the 79-patch series down to a single patch.

2026-01-14drm/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().
