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.

2025-02-24drm/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.

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.

2025-02-24drm/xe/userptr: fix EFAULT handlingMatthew Auld
Currently we treat EFAULT from hmm_range_fault() as a non-fatal error when called from xe_vm_userptr_pin() with the idea that we want to avoid killing the entire vm and chucking an error, under the assumption that the user just did an unmap or something, and has no intention of actually touching that memory from the GPU. At this point we have already zapped the PTEs so any access should generate a page fault, and if the pin fails there also it will then become fatal. However it looks like it's possible for the userptr vma to still be on the rebind list in preempt_rebind_work_func(), if we had to retry the pin again due to something happening in the caller before we did the rebind step, but in the meantime needing to re-validate the userptr and this time hitting the EFAULT.

For the actual pin, so long as the vma is tracked on either list it should get picked up on the next pin, however it looks possible for the vma to get nuked but still be present on this per vm pin_list leading to corruption. An alternative might be then to instead just remove the link when destroying the vma. v2: - Also add some asserts. - Keep the overzealous locking so that we are consistent with the docs; updating the docs and related bits will be done as a follow up.

2025-02-24drm/sched: Add internal job peek/pop APITvrtko Ursulin
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.

git://git.kernel.org/pub/scm/linux/kernel/git/trace/linux-trace Pull tracing fixes from Steven Rostedt: "Function graph accounting fixes: - Fix the manage ops hashes The function graph registers a "manager ops" and "sub-ops" to ftrace. The manager ops does not have any callback but calls the sub-ops callbacks. The manage ops hashes (what is used to tell ftrace what functions to attach to) is built on the sub-ops it manages. There was an error in the way it built the hash. An empty hash means to attach to all functions. When the manager ops had one sub-ops it properly copied its hash. But when the manager ops had more than one sub-ops, it went into a loop to make a set of all functions it needed to add to the hash. If any of the subops hashes was empty, that would mean to attach to all functions. The error was that the first iteration of the loop passed in an empty hash to start with in order to add the other hashes. That starting hash was mistaken as to attach to all functions. This made the manage ops attach to all functions whenever it had two or more sub-ops, even if each sub-op was attached to only a single function. - Do not add duplicate entries to the manager ops hash If two or more subops hashes trace the same function, an entry for that function will be added to the manager ops for each subops. This causes waste and extra overhead. Fprobe accounting fixes: - Remove last function from fprobe hash Fprobes has a ftrace hash to manage which functions an fprobe is attached to. It also has a counter of how many fprobes are attached. When the last fprobe is removed, it unregisters the fprobe from ftrace but does not remove the functions the last fprobe was attached to from the hash. This leaves the old functions attached. When a new fprobe is added, the fprobe infrastructure attaches to not only the functions of the new fprobe, but also to the functions of the last fprobe. - Fix accounting of the fprobe counter When a fprobe is added, it updates a counter. If the counter goes from zero to one, it attaches its ops to ftrace. When an fprobe is removed, the counter is decremented. If the counter goes from 1 to zero, it removes the fprobes ops from ftrace. There was an issue where if two fprobes trace the same function, the addition of each fprobe would increment the counter. But when removing the first of the fprobes, it would notice that another fprobe is still attached to one of its functions no it does not remove the functions from the ftrace ops. But it also did not decrement the counter, so when the last fprobe is removed, the counter is still one. This leaves the fprobes callback still registered with ftrace and it being called by the functions defined by the fprobes ops hash. Worse yet, because all the functions from the fprobe ops hash have been removed, that tells ftrace that it wants to trace all functions. Thus, this puts the state of the system where every function is calling the fprobe callback handler (which does nothing as there are no registered fprobes), but this causes a good 13% slow down of the entire system. Other updates: - Add a selftest to test the above issues to prevent regressions. - Fix preempt count accounting in function tracing Better recursion protection was added to function tracing which added another layer of preempt disable. As the preempt_count gets traced in the event, it needs to subtract the amount of preempt disabling the tracer does to record what the preempt_count was when the trace was triggered. - Fix memory leak in output of set_event A variable is passed by the seq_file functions in the location that is set by the return of the next() function. The start() function allocates it and the stop() function frees it. But when the last item is found, the next() returns NULL which leaks the data that was allocated in start(). The m->private is used for something else, so have next() free the data when it returns NULL, as stop() will then just receive NULL in that case" * tag 'ftrace-v6.14-rc3' of git://git.kernel.org/pub/scm/linux/kernel/git/trace/linux-trace: tracing: Fix memory leak when reading set_event file ftrace: Correct preemption accounting for function tracing. selftests/ftrace: Update fprobe test to check enabled_functions file fprobe: Fix accounting of when to unregister from function graph fprobe: Always unregister fgraph function from ops ftrace: Do not add duplicate entries in subops manager ops ftrace: Fix accounting of adding subops to a manager ops
