2025-02-20drm/ast: cursor: Move format conversion to shared helperThomas Zimmermann3-55/+89
User-space cursor-image data is encoded in ARBG8888, while hardware supports ARGB4444. Implement the format conversion as part of the format-helper framework, so that other drivers can benefit. This allows to respect the damage area of the cursor update. In previous code, all cursor image data had to be converted on each update. Now, only the changed areas require an update. The hardware image is always updated completely, as it is required for the checksum update. The format-conversion helper still contains the old implementation's optimization of writing 2 output pixels at the same time.

2025-02-19drm/amdkfd: Fix error handling for missing PASID in 'kfd_process_device_init_vm'Srinivasan Shanmugam1-0/+1
In the kfd_process_device_init_vm function, a valid error code is now returned when the associated Process Address Space ID (PASID) is not present. If the address space virtual memory (avm) does not have an associated PASID, the function sets the ret variable to -EINVAL before proceeding to the error handling section. This ensures that the calling function, such as kfd_ioctl_acquire_vm, can appropriately handle the error, thereby preventing any issues during virtual memory initialization.

2025-02-19drm/amdgpu: Replace Mutex with Spinlock for RLCG register access to avoid ↵Srinivasan Shanmugam3-4/+6
Priority Inversion in SRIOV RLCG Register Access is a way for virtual functions to safely access GPU registers in a virtualized environment., including TLB flushes and register reads. When multiple threads or VFs try to access the same registers simultaneously, it can lead to race conditions. By using the RLCG interface, the driver can serialize access to the registers. This means that only one thread can access the registers at a time, preventing conflicts and ensuring that operations are performed correctly. Additionally, when a low-priority task holds a mutex that a high-priority task needs, ie., If a thread holding a spinlock tries to acquire a mutex, it can lead to priority inversion. register access in amdgpu_virt_rlcg_reg_rw especially in a fast code path is critical. The call stack shows that the function amdgpu_virt_rlcg_reg_rw is being called, which attempts to acquire the mutex. This function is invoked from amdgpu_sriov_wreg, which in turn is called from gmc_v11_0_flush_gpu_tlb. The [ BUG: Invalid wait context ] indicates that a thread is trying to acquire a mutex while it is in a context that does not allow it to sleep (like holding a spinlock).

2025-02-19drm/i915/dp: Fix error handling during 128b/132b link trainingImre Deak1-1/+14
At the end of a 128b/132b link training sequence, the HW expects the transcoder training pattern to be set to TPS2 and from that to normal mode (disabling the training pattern). Transitioning from TPS1 directly to normal mode leaves the transcoder in a stuck state, resulting in page-flip timeouts later in the modeset sequence. Atm, in case of a failure during link training, the transcoder may be still set to output the TPS1 pattern. Later the transcoder is then set from TPS1 directly to normal mode in intel_dp_stop_link_train(), leading to modeset failures later as described above. Fix this by setting the training patter to TPS2, if the link training failed at any point. The clue in the specification about the above HW behavior is the explicit mention that TPS2 must be set after the link training sequence (and there isn't a similar requirement specified for the 8b/10b link training), see the Bspec links below. v2: Add bspec aspect/link to the commit log.
