2023-09-26drm/amd/display: determine fast update only before commit minimal transition ↵Wenjing Liu
state [why] commit minimal transition state would update current state to new state with surface and stream update applied. If we determine fast update only after we have committed the minimal transition state based on new state, we will skip committing the full new state. [how] determine fast update only earlier based on the actaul currents state. Only skip full commit when the transition between actual current state and new state is fast update only.

2023-09-26drm/amdkfd: fix some race conditions in vram buffer alloc/free of svm codeXiaogang Chen
This patch fixes: 1: ref number of prange's svm_bo got decreased by an async call from hmm. When wait svm_bo of prange got released we shoul also wait prang->svm_bo become NULL, otherwise prange->svm_bo may be set to null after allocate new vram buffer. 2: During waiting svm_bo of prange got released in a while loop should reschedule current task to give other tasks oppotunity to run, specially the the workque task that handles svm_bo ref release, otherwise we may enter to softlock.

2023-09-26i915/guc: Get runtime pm in busyness worker only if already activeUmesh Nerlige Ramappa
Ideally the busyness worker should take a gt pm wakeref because the worker only needs to be active while gt is awake. However, the gt_park path cancels the worker synchronously and this complicates the flow if the worker is also running at the same time. The cancel waits for the worker and when the worker releases the wakeref, that would call gt_park and would lead to a deadlock. The resolution is to take the global pm wakeref if runtime pm is already active. If not, we don't need to update the busyness stats as the stats would already be updated when the gt was parked. Note: - We do not requeue the worker if we cannot take a reference to runtime pm since intel_guc_busyness_unpark would requeue the worker in the resume path. - If the gt was parked longer than time taken for GT timestamp to roll over, we ignore those rollovers since we don't care about tracking the exact GT time. We only care about roll overs when the gt is active and running workloads. - There is a window of time between gt_park and runtime suspend, where the worker may run. This is acceptable since the worker will not find any new data to update busyness. v2: (Daniele) - Edit commit message and code comment - Use runtime pm in the worker - Put runtime pm after enabling the worker - Use Link tag and add Fixes tag v3: (Daniele) - Reword commit and comments and add details Link: https://gitlab.freedesktop.org/drm/intel/-/issues/7077 Fixes: 77cdd054dd2c ("drm/i915/pmu: Connect engine busyness stats from GuC to pmu") Signed-off-by: Umesh Nerlige Ramappa <umesh.nerlige.ramappa@intel.com> Reviewed-by: Daniele Ceraolo Spurio <daniele.ceraolospurio@intel.com> Link: https://patchwork.freedesktop.org/patch/msgid/20230925192117.2497058-1-umesh.nerlige.ramappa@intel.com (cherry picked from commit e2f99b79d4c594cdf7ab449e338d4947f5ea8903) Signed-off-by: Rodrigo Vivi <rodrigo.vivi@intel.com>

Rename struct drm_gpuva_manager to struct drm_gpuvm including corresponding functions. This way the GPUVA manager's structures align very well with the documentation of VM_BIND [1] and VM_BIND locking [2]. It also provides a better foundation for the naming of data structures and functions introduced for implementing a common dma-resv per GPU-VM including tracking of external and evicted objects in subsequent patches.

2023-09-25drm/imx/dcss: Call drm_atomic_helper_shutdown() at shutdown timeDouglas Anderson
Based on grepping through the source code this driver appears to be missing a call to drm_atomic_helper_shutdown() at system shutdown time. Among other things, this means that if a panel is in use that it won't be cleanly powered off at system shutdown time. The fact that we should call drm_atomic_helper_shutdown() in the case of OS shutdown/restart comes straight out of the kernel doc "driver instance overview" in drm_drv.c.

2023-09-25drm/i915/irq: Clear GFX_MSTR_IRQ as part of IRQ resetGustavo Sousa
Starting with Xe_LP+, GFX_MSTR_IRQ contains status bits that have W1C behavior. If we do not properly reset them, we would miss delivery of interrupts if a pending bit is set when enabling IRQs. As an example, the display part of our probe routine contains paths where we wait for vblank interrupts. If a display interrupt was already pending when enabling IRQs, we would time out waiting for the vblank. Avoid the potential issue by clearing GFX_MSTR_IRQ as part of the IRQ reset. v2: - Move logic from gen11_gt_irq_reset() to dg1_irq_reset().

2023-09-25drm/i915/gt: remove a static inline that requires including i915_drv.hJani Nikula
It's actively harmful to add static inlines in headers that require you to pull in more headers. Remove the include added in commit f1530f912ed8 ("drm/i915/gt: Apply workaround 22016122933 correctly"). We see that there's already an implicit dependency on the i915_drv.h that we need to address too.

2023-09-25drm/simpledrm: Add support for multiple "power-domains"Janne Grunau
Multiple power domains need to be handled explicitly in each driver. The driver core can not handle it automatically since it is not aware of power sequencing requirements the hardware might have. This is not a problem for simpledrm since everything is expected to be powered on by the bootloader. simpledrm has just ensure it remains powered on during its lifetime. This is required on Apple silicon M2 and M2 Pro/Max/Ultra desktop systems. The HDMI output initialized by the bootloader requires keeping the display controller and a DP phy power domain on.
