Rename them active_links, stream_encoders[] and mgr for clarity. Note that is_mst and mst_detect are not included, as they're also relevant for non-mst. The sub-struct is for active mst.

2025-02-28drm/i915/display: Make POWER_DOMAIN_*() always result in enum ↵Gustavo Sousa
intel_display_power_domain In the hope of contributing to type safety in our code, let's ensure that the type returned by the POWER_DOMAIN_*() macros is always of type enum intel_display_power_domain. v2: - Remove accidental +1 in definition of POWER_DOMAIN_PIPE().

2025-02-28drm/i915/display: Use explicit base values in POWER_DOMAIN_*() macrosGustavo Sousa
Although we have comments in intel_display_limits.h saying that the code expects PIPE_A and TRANSCODER_A to be zero, it doesn't hurt to add them as explicit base values for calculating the power domain offset in POWER_DOMAIN_*() macros. On the plus side, we have that this: * Fixes a warning reported by kernel test robot <lkp@intel.com> about doing arithmetic with two different enum types. * Makes the code arguably more robust (in the unlikely event of those bases becoming non-zero). v2: - Prefer using explicit base values instead of simply casting the macro argument to int. (Ville) - Update commit message to match the new approach (for reference, the old message subject was "drm/i915/display: Use explicit cast in POWER_DOMAIN_*() macros").

2025-02-28drm/i915/display: Use IP version check for Wa_14020863754Gustavo Sousa
Wa_14020863754 applies to the display IP, so we should be checking on display IP version instead of platform. So, let's replace display->platform.battlemage with the proper IP version check (14.01 for Xe2_HPD). Furthermore, for workarounds, we should be checking on full IP versions to avoid applying the workaround to some variant of the IP that could theoretically appear in the future (which is likely to have a different minor release number), since the issue addressed by the workaround could be fixed in such new release.

2025-02-27drm/i915/dsb: Allow DSB based commits when scalers are in useVille Syrjälä
Have DSB perform plane scaler programming as well. Changes to pfit/pipe scaler are not being done on the dsb since those take the fastset path. However we do now allow DSB based plane updates when the pfit/pipe scaler is currently enabled (the pfit/pipe scaler just won't be touched by the DSB). Fortunately the hardware issue where some scaler registers are latched at frame start and some at start of vblank has been fixed on icl+ (IIRC), and since DSB is tgl+ only we don't have to do any changes to the DSB vblank evasion. Not that we handle that hardware issue correctly in the CPU vblank evasion either...

2025-02-27drm/i915/dsb: Allow DSB based updates without planesVille Syrjälä
We don't actually need any planes to get updated in order to perform the commit on the DSB. Allow DSB based updates even when we don't touch planes. The main benefit here is that pure LUT updates will now go through the DSB path and therefore we don't have to do vblank evasion/etc. on the CPU. I think the reason I had this excluded was that I was originally contemplating using frame/flip timestamps as a way to complete the commits. But I had to scrap that idea when it turned out that those timestamp get corrupted when DSB is poking at random registers.

2025-02-25drm/i915/dp_mst: Fix encoder HW state readout for UHBR MSTImre Deak
The encoder HW/SW state verification should use a SW state which stays unchanged while the encoder/output is active. The intel_dp::is_mst flag used during state computation to choose between the DP SST/MST modes can change while the output is active, if the sink gets disconnected or the MST topology is removed for another reason. A subsequent state verification using intel_dp::is_mst leads then to a mismatch if the output is disabled/re-enabled without recomputing its state. Use the encoder's active MST link count instead, which will be always non-zero for an active MST output and will be zero for SST. Fixes: 35d2e4b75649 ("drm/i915/ddi: start distinguishing 128b/132b SST and MST at state readout") Fixes: 40d489fac0e8 ("drm/i915/ddi: handle 128b/132b SST in intel_ddi_read_func_ctl()") Cc: Jani Nikula <jani.nikula@intel.com> Reviewed-by: Jani Nikula <jani.nikula@intel.com> Signed-off-by: Imre Deak <imre.deak@intel.com> Link: https://patchwork.freedesktop.org/patch/msgid/20250224093242.1859583-1-imre.deak@intel.com

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
