2025-02-27drm/nouveau: Avoid multiple -Wflex-array-member-not-at-end warningsGustavo A. R. Silva
-Wflex-array-member-not-at-end was introduced in GCC-14, and we are getting ready to enable it, globally. So, in order to avoid ending up with flexible-array members in the middle of other structs, we use the `struct_group_tagged()` helper to separate the flexible arrays from the rest of the members in the flexible structures. We then use the newly created tagged `struct nvif_ioctl_v0_hdr` and `struct nvif_ioctl_mthd_v0_hdr` to replace the type of the objects causing trouble in multiple structures. We also want to ensure that when new members need to be added to the flexible structures, they are always included within the newly created tagged structs. For this, we use `static_assert()`. This ensures that the memory layout for both the flexible structure and the new tagged struct is the same after any changes. So, with these changes, fix the following warnings: drivers/gpu/drm/nouveau/nvif/object.c:60:38: warning: structure containing a flexible array member is not at the end of another structure [-Wflex-array-member-not-at-end] drivers/gpu/drm/nouveau/nvif/object.c:233:38: warning: structure containing a flexible array member is not at the end of another structure [-Wflex-array-member-not-at-end] drivers/gpu/drm/nouveau/nvif/object.c:214:38: warning: structure containing a flexible array member is not at the end of another structure [-Wflex-array-member-not-at-end] drivers/gpu/drm/nouveau/nvif/object.c:152:38: warning: structure containing a flexible array member is not at the end of another structure [-Wflex-array-member-not-at-end] drivers/gpu/drm/nouveau/nvif/object.c:138:38: warning: structure containing a flexible array member is not at the end of another structure [-Wflex-array-member-not-at-end] drivers/gpu/drm/nouveau/nvif/object.c:104:38: warning: structure containing a flexible array member is not at the end of another structure [-Wflex-array-member-not-at-end] drivers/gpu/drm/nouveau/nouveau_svm.c:83:35: warning: structure containing a flexible array member is not at the end of another structure [-Wflex-array-member-not-at-end] drivers/gpu/drm/nouveau/nouveau_svm.c:82:30: warning: structure containing a flexible array member is not at the end of another structure [-Wflex-array-member-not-at-end] Signed-off-by: Gustavo A.

2025-02-27accel/amdxdna: Check interrupt register before mailbox_rx_worker exitsLizhi Hou
There is a timeout failure been found during stress tests. If the firmware generates a mailbox response right after driver clears the mailbox channel interrupt register, the hardware will not generate an interrupt for the response. This causes the unexpected mailbox command timeout. To handle this failure, driver checks the interrupt register before exiting mailbox_rx_worker(). If there is a new response, driver goes back to process it.

2025-02-27drm/rockchip: Fix shutdown when no drm-device is set upHeiko Stuebner
When the drm-driver probes, it mainly creates the component device, where all the sub-drivers (vops, hdmi, etc) hook into. This will cause the shutdown handler to get called on shutdown, even though the drm-device might not have been set up, or the component bind might have failed. So use the new component helper to check whether the drm-device is up and only then call the drm-atomic helper to release all the drm magic. This prevents failures when the drm-device is never set, or has been freed up already for example by a probe-defer during the component bind.

2025-02-27drivers: base: component: add function to query the bound statusHeiko Stuebner
The component helpers already expose the bound status in debugfs, but at times it might be necessary to also check that state in the kernel and act differently depending on the result. For example the shutdown handler of a drm-driver might need to stop a whole output pipeline if the drm device is up and running, but may run into problems if that drm-device has never been set up before, for example because the binding deferred. So add a little helper that returns the bound status for a componet device.

2025-02-25drm/msm/dp: Add support for LTTPR handlingAbel Vesa
Link Training Tunable PHY Repeaters (LTTPRs) are defined in DisplayPort 1.4a specification. As the name suggests, these PHY repeaters are capable of adjusting their output for link training purposes. According to the DisplayPort standard, LTTPRs have two operating modes: - non-transparent - it replies to DPCD LTTPR field specific AUX requests, while passes through all other AUX requests - transparent - it passes through all AUX requests. Switching between these two modes is done by the DPTX by issuing an AUX write to the DPCD PHY_REPEATER_MODE register. The msm DP driver is currently lacking any handling of LTTPRs. This means that if at least one LTTPR is found between DPTX and DPRX, the link training would fail if that LTTPR was not already configured in transparent mode. The section 3.6.6.1 from the DisplayPort v2.0 specification mandates that before link training with the LTTPR is started, the DPTX may place the LTTPR in non-transparent mode by first switching to transparent mode and then to non-transparent mode. This operation seems to be needed only on first link training and doesn't need to be done again until device is unplugged. It has been observed on a few X Elite-based platforms which have such LTTPRs in their board design that the DPTX needs to follow the procedure described above in order for the link training to be successful. So add support for reading the LTTPR DPCD caps to figure out the number of such LTTPRs first. Then, for platforms (or Type-C dongles) that have at least one such an LTTPR, set its operation mode to transparent mode first and then to non-transparent, just like the mentioned section of the specification mandates.

2025-02-25drm/i915/dp: Use the generic helper to control LTTPR transparent modeAbel Vesa
LTTPRs operating modes are defined by the DisplayPort standard and the generic framework now provides a helper to switch between them, which is handling the explicit disabling of non-transparent mode and its disable->enable sequence mentioned in the DP Standard v2.0 section 3.6.6.1. So use the new drm generic helper instead as it makes the code a bit cleaner. Since the driver specific implementation holds the lttrp_common_caps, if the call to the drm generic helper fails, the lttrp_common_caps need to be updated as the helper has already rolled back to transparent mode.

2025-02-25drm/nouveau/dp: Use the generic helper to control LTTPR transparent modeAbel Vesa
LTTPRs operating modes are defined by the DisplayPort standard and the generic framework now provides a helper to switch between them, which is handling the explicit disabling of non-transparent mode and its disable->enable sequence mentioned in the DP Standard v2.0 section 3.6.6.1. So use the new drm generic helper instead as it makes the code a bit cleaner.

2025-02-25drm/dp: Add helper to set LTTPRs in transparent modeAbel Vesa
According to the DisplayPort standard, LTTPRs have two operating modes: - non-transparent - it replies to DPCD LTTPR field specific AUX requests, while passes through all other AUX requests - transparent - it passes through all AUX requests. Switching between this two modes is done by the DPTX by issuing an AUX write to the DPCD PHY_REPEATER_MODE register. Add a generic helper that allows switching between these modes. Also add a generic wrapper for the helper that handles the explicit disabling of non-transparent mode and its disable->enable sequence mentioned in the DP Standard v2.0 section 3.6.6.1. Do this in order to move this handling out of the vendor specific driver implementation into the generic framework.

2025-02-24drm/repaper: fix integer overflows in repeat functionsNikita Zhandarovich
There are conditions, albeit somewhat unlikely, under which right hand expressions, calculating the end of time period in functions like repaper_frame_fixed_repeat(), may overflow. For instance, if 'factor10x' in repaper_get_temperature() is high enough (170), as is 'epd->stage_time' in repaper_probe(), then the resulting value of 'end' will not fit in unsigned int expression. Mitigate this by casting 'epd->factored_stage_time' to wider type before any multiplication is done. Found by Linux Verification Center (linuxtesting.org) with static analysis tool SVACE.

2025-02-24drm/bridge: ti-sn65dsi86: Check for CONFIG_PWM using IS_REACHABLE()Uwe Kleine-König
Currently CONFIG_PWM is a bool but I intend to change it to tristate. If CONFIG_PWM=m in the configuration, the cpp symbol CONFIG_PWM isn't defined and so the PWM code paths in the ti-sn65dsi86 driver are not used. The correct way to check for CONFIG_PWM is using IS_REACHABLE which does the right thing for all cases CONFIG_DRM_TI_SN65DSI86 ∈ { y, m } x CONFIG_PWM ∈ { y, m, n }. There is no change until CONFIG_PWM actually becomes tristate.

Idea is to add helpers for peeking and popping jobs from entities with the goal of decoupling the hidden assumption in the code that queue_node is the first element in struct drm_sched_job. That assumption usually comes in the form of: while ((job = to_drm_sched_job(spsc_queue_pop(&entity->job_queue)))) Which breaks if the queue_node is re-positioned due to_drm_sched_job being implemented with a container_of. This also allows us to remove duplicate definitions of to_drm_sched_job.
