2023-08-24drm/nouveau: sched: avoid job races between entitiesDanilo Krummrich
If a sched job depends on a dma-fence from a job from the same GPU scheduler instance, but a different scheduler entity, the GPU scheduler does only wait for the particular job to be scheduled, rather than for the job to fully complete. This is due to the GPU scheduler assuming that there is a scheduler instance per ring. However, the current implementation, in order to avoid arbitrary amounts of kthreads, has a single scheduler instance while scheduler entities represent rings. As a workaround, set the DRM_SCHED_FENCE_DONT_PIPELINE for all out-fences in order to force the scheduler to wait for full job completion for dependent jobs from different entities and same scheduler instance. There is some work in progress [1] to address the issues of firmware schedulers; once it is in-tree the scheduler topology in Nouveau should be re-worked accordingly.

2023-08-23drm/i915: Fix HPD polling, reenabling the output poll work as neededImre Deak
After the commit in the Fixes: line below, HPD polling stopped working on i915, since after that change calling drm_kms_helper_poll_enable() doesn't restart drm_mode_config::output_poll_work if the work was stopped (no connectors needing polling) and enabling polling for a connector (during runtime suspend or detecting an HPD IRQ storm). After the above change calling drm_kms_helper_poll_enable() is a nop after it's been called already and polling for some connectors was disabled/re-enabled.

2023-08-23platform: mellanox: mlx-platform: Modify power off callbackVadim Pasternak
Extend platform power off callback with kernel_halt() call. When powering off, the process involves setting a halt bit in the register space, which is then activated after a certain delay and power off auxiliary power. By invoking `kernel_halt()` within this timeframe, the intention is to facilitate a clean system power-off sequence.
