Currently, NO_PREFETCH is passed implicitly through drm_nouveau_gem_pushbuf_push::length and drm_nouveau_exec_push::va_len. Since this is a direct representation of how the HW is programmed it isn't really future proof for a uAPI. Hence, fix this up for the new uAPI and split up the va_len field of struct drm_nouveau_exec_push, such that we keep 32bit for va_len and 32bit for flags. For drm_nouveau_gem_pushbuf_push::length at least provide NOUVEAU_GEM_PUSHBUF_NO_PREFETCH to indicate the bit shift. While at it, fix up nv50_dma_push() as well, such that the caller doesn't need to encode the NO_PREFETCH flag into the length parameter. Signed-off-by:

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.

Add the device link when panel bridge is attached and delete the link when panel bridge is detached. The drm device is the consumer while the panel device is the supplier. This makes sure that the drm device suspends eariler and resumes later than the panel device, hence resolves problems where the order is reversed, like the problematic case mentioned in the below link.

atomic_get_input_bus_fmts is only implemented for LVDS decoders, resulting that LVDS encoders only support bus format MEDIA_BUS_FMT_FIXED. This results in warnings like: mxsfb 21c8000.lcdif: Bridge does not provide bus format, assuming MEDIA_BUS_FMT_RGB888_1X24. Please fix bridge driver by handling atomic_get_input_bus_fmts. Fix this by reusing lvds_codec_atomic_get_input_bus_fmts currently used for LVDS decoders. Use RGB888_1X24 for LVDS encoders.
