[RFC v2 18/18] drm/display/dp_mst: Move all payload info into the atomic state

Now that we've finally gotten rid of the non-atomic MST users leftover in the kernel, we can finally get rid of all of the legacy payload code we have and move as much as possible into the MST atomic state structs. The main purpose of this is to make the MST code a lot less confusing to work on, as

Currently, we set drm_dp_atomic_payload->time_slots to 0 in order to indicate that we're about to delete a payload in the current atomic state. Since we're going to be dropping all of the legacy code for handling the payload table however, we need to be able to ensure that we still keep track of th

Right now, radeon is technically the only non-atomic driver still making use of the MST helpers - and thus the final user of all of the legacy MST helpers. Originally I was going to look into seeing if we could move legacy MST into the radeon driver itself, however: * SI and CIK both can use amdgp

This isn't a very typical scenario an

[RFC v2 10/18] drm/display/dp_mst: Fix modeset tracking in drm_dp_atomic_release_vcpi_slots()

Currently with the MST helpers we avoid releasing payloads _and_ avoid pulling in the MST state if there aren't any actual payload changes. While we want to keep the first step, we need to now make sure that we're always pulling in the MST state on all modesets that can modify payloads - even if th

[RFC v2 09/18] drm/display/dp_mst: Don't open code modeset checks for releasing time slots

I'm not sure why, but at the time I originally wrote the find/release time slot helpers I thought we should avoid keeping modeset tracking out of the MST helpers. In retrospect though there's no actual good reason to do this, and the logic has ended up being identical across all the drivers using t

For some reason we mention returning 0 if "slots have been added back to drm_dp_mst_topology_state->avail_slots". This is totally misleading, avail_slots is simply for figuring out the total number of slots available in total on the topology and has no relation to the current payload allocations.

[PATCH 2/2] [WIP]: media: Add Synaptics compressed tiled format

From: "Hsia-Jun(Randy) Li" The most of detail has been written in the drm. Please notice that the tiled formats here request one more plane for storing the motion vector metadata. This buffer won't be compressed, so you can't append it to luma or chroma plane. Signed-off-by: Hsia-Jun(Randy) Li
