2024-11-04drm/amdkfd: Use dynamic allocation for CU occupancy array in ↵Srinivasan Shanmugam
'kfd_get_cu_occupancy()' The `kfd_get_cu_occupancy` function previously declared a large `cu_occupancy` array as a local variable, which could lead to stack overflows due to excessive stack usage. This commit replaces the static array allocation with dynamic memory allocation using `kcalloc`, thereby reducing the stack size. This change avoids the risk of stack overflows in kernel space, in scenarios where `AMDGPU_MAX_QUEUES` is large. The allocated memory is freed using `kfree` before the function returns to prevent memory leaks.

2024-11-04drm/amdgpu: prevent NULL pointer dereference if ATIF is not supportedAntonio Quartulli
acpi_evaluate_object() may return AE_NOT_FOUND (failure), which would result in dereferencing buffer.pointer (obj) while being NULL. Although this case may be unrealistic for the current code, it is still better to protect against possible bugs. Bail out also when status is AE_NOT_FOUND.

2024-11-04drm/amd/display: Prune Invalid Modes For HDMI OutputFangzhi Zuo
[Why] 1. HDMI does not have 6 bpc support. Having 6 bpc pass validation does not comply with spec. 2. Validate 420 only for native HDMI, but not apply to pcon use case. 3. Current mode validation log is not readable. [how] 1. Cap 8 bpc for dp-hdmi converter. 2. Validate yuv420 for pcon use case as well, if rgb/yuv444 8bpc cannot fit into pcon bw limitation of the link from the converter to HDMI sink. 3.

2024-11-04drm/amd/display: Don't write DP_MSTM_CTRL after LTWayne Lin
[Why] Observe after suspend/resme, we can't light up mst monitors under specific mst hub. The reason is that driver still writes DPCD DP_MSTM_CTRL after LT. It's forbidden even we write the same value for that dpcd register. [How] We already resume the mst branch device dpcd settings during resume_mst_branch_status(). Leverage drm_dp_mst_topology_queue_probe() to only probe the topology, not calling drm_dp_mst_topology_mgr_resume() which will set DP_MSTM_CTRL as well.
