Unfortunately the DP MST helpers do not have much in the way of debugging utilities. So, let's add some! This adds basic debugging output for down sideband requests that we send from the driver, so that we can actually discern what's happening when sideband requests timeout. Since there wasn't really a good way of testing that any of this worked, I ended up writing simple selftests

Noticed this while working on adding a drm_dp_decode_sideband_req(). DP_POWER_DOWN_PHY/DP_POWER_UP_PHY both use the same struct, so we can just combine their cases.

Once upon a time, hotplugging devices on MST branches actually worked in DRM. Now, it only works in amdgpu (likely because of how it's hotplug handlers are implemented). On both i915 and nouveau, hotplug notifications from MST branches are noticed - but trying to respond to them causes messaging timeouts and causes the whole topology state to go out of sync with reality, usually resulting in

Which reduces indentation and makes this function more legible.

This is the large series for adding MST suspend/resume reprobing that I've been working on for quite a while now. In addition, I: - Refactored and cleaned up any code I ended up digging through in the process of understanding how some parts of these helpers worked. - Added some debugging tools along the way that I ended up needing to figure out some issues in my own code Note that

There's a couple of changes here, so to summarize: * Remove the big ugly mgr->up_req_recv.have_eomt conditional to save on indenting * Store &mgr->up_req_recv.initial_hdr in a variable so we don't keep going over 80 character long lines * De-duplicate code for calling drm_dp_send_up_ack_reply() and getting the MSTB via it's GUID * Remove all of the duplicate calls to

This set contains fixes for some "wouldn't it be nice if" issues, however most of the patches seen here have been on the MLs, but were left unreviewed. Lee Jones (42): drm/amd/amdgpu/atombios_encoders: Remove set but unused variable 'backlight_level' drm/armada/armada_overlay: Staticify local function 'armada_overlay_duplicate_state'

This is a complicated one. Essentially, there's currently a problem in the MST core that hasn't really caused any issues that we're aware of (emphasis on "that we're aware of"): locking. When we go through and probe the link addresses and path resources in a topology, we hold no locks when updating ports with said information. The members I'm referring to in
