2024-12-03drm/xe: Move the coredump registration to the worker threadJohn Harrison
Adding lockdep checking to the coredump code showed that there was an existing violation. The dev_coredumpm_timeout() call is used to register the dump with the base coredump subsystem. However, that makes multiple memory allocations, only some of which use the GFP_ flags passed in. So that also needs to be deferred to the worker function where it is safe to allocate with arbitrary flags. In order to not add protoypes for the callback functions, moving the _timeout call also means moving the worker thread function to later in the file. v2: Rebased after other changes to the worker function.

The msm_dp_utils_pack_sdp_header() accepts an unlimited-size u32 pointer for the header output, while it expects a two-element array. It performs a sizeof check which is always true on 64-bit platforms (since sizeof(u32*) is 8) and is always false on 32-bit platforms. It returns an error code which nobody actually checks.

2024-12-02drm/xe: Add mutex locking to devcoredumpJohn Harrison
There are now multiple places that can trigger a coredump. Some of which can happen in parallel. There is already a check against capturing multiple dumps sequentially, but without locking it doesn't guarantee to work against concurrent dumps. And if two dumps do happen in parallel, they can end up doing Bad Things such as one call stack freeing the data the other call stack is still processing. Which leads to a crashed kernel. Further, it is possible for the DRM timeout to expire and trigger a free of the capture while a user is still reading that capture out through sysfs. Again leading to dodgy pointer problems. So, add a mutext lock around the capture, read and free functions to prevent inteference. v2: Swap tiny scope spin_lock for larger scope mutex and fix kernel-doc comment (review feedback from Matthew Brost) v3: Move mutex locks to exclude worker thread and add reclaim annotation (review feedback from Matthew Brost) v4: Fix typo.

2024-12-02drm/amd/pm: fix and simplify workload handlingAlex Deucher
smu->workload_mask is IP specific and should not be messed with in the common code. The mask bits vary across SMU versions. Move all handling of smu->workload_mask in to the backends and simplify the code. Store the user's preference in smu->power_profile_mode which will be reflected in sysfs. For internal driver profile switches for KFD or VCN, just update the workload mask so that the user's preference is retained. Remove all of the extra now unused workload related elements in the smu structure. v2: use refcounts for workload profiles v3: rework based on feedback from Lijo v4: fix the refcount on failure, drop backend mask v5: rework custom handling v6: handle failure cleanup with custom profile v7: Update documentation Reviewed-by: Lijo Lazar <lijo.lazar@amd.com> Signed-off-by: Alex Deucher <alexander.deucher@amd.com> Cc: Kenneth Feng <kenneth.feng@amd.com> Cc: Lijo Lazar <lijo.lazar@amd.com> Cc: stable@vger.kernel.org # 6.11.x

2024-12-01Get rid of 'remove_new' relic from platform driver structLinus Torvalds
The continual trickle of small conversion patches is grating on me, and is really not helping. Just get rid of the 'remove_new' member function, which is just an alias for the plain 'remove', and had a comment to that effect: /* * .remove_new() is a relic from a prototype conversion of .remove(). * New drivers are supposed to implement .remove(). Once all drivers are * converted to not use .remove_new any more, it will be dropped. */ This was just a tree-wide 'sed' script that replaced '.remove_new' with '.remove', with some care taken to turn a subsequent tab into two tabs to make things line up. I did do some minimal manual whitespace adjustment for places that used spaces to line things up. Then I just removed the old (sic) .remove_new member function, and this is the end result. No more unnecessary conversion noise. Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>
2024-11-30drm/xe/display: Flush DMC wakelock release work on runtime suspendGustavo Sousa
We currently are not calling display runtime suspend functions when D3cold is not allowed. Because of that, we end up not disabling dynamic DC states (and do not go to DC9). With dynamic DC states enabled, we will also have DMC wakelock enabled. Since we use a delayed work to release the DMC wakelock, the work might get executed a little too late (after the PCI device has been put to D3hot) and we get a timeout warning ("DMC wakelock release timed out") because the MMIO for releasing the wakelock will be invalid after that point. To fix that, make sure we flush the release work at the end of xe_display_pm_runtime_suspend_late(). We can do that unconditionally because, if there is no pending work, that turns into a no-op.

2024-11-30drm/xe/display: Extract xe_display_pm_runtime_suspend_late()Gustavo Sousa
The current behavior for the runtime suspend case is that xe_display_pm_suspend_late() is only called when D3cold is allowed. Let's incorporate that behavior into a function specific to runtime PM and call it xe_display_pm_runtime_suspend_late(). With that, we keep stuff a bit more self-contained and allow having a place for adding more "late display runtime suspend"-related logic that isn't dependent on the "D3cold allowed" state. v2: - Fix typo in that caused xe_display_pm_runtime_suspend_late() to call itself instead of xe_display_pm_suspend_late(). - Add the empty version of xe_display_pm_runtime_suspend_late() for the !CONFIG_DRM_XE_DISPLAY case.
