VCPI is only sort of the correct term here, originally the majority of this
code simply referred to timeslots vaguely as "slots" - and since I started
working on it and adding atomic functionality, the name "VCPI slots" has
been used to represent time slots.
Now that we actually have consistent
In retrospect, the name I chose for this originally is confusing, as
there's a lot more info in here then just the VCPI. This really should be
called a payload. Let's make it more obvious that this is meant to be
related to the atomic state and is about payloads by renaming it to
As Daniel Vetter pointed out, if we only use the atomic modesetting locks
with MST it's technically possible for a driver with non-blocking modesets
to race when it comes to MST displays - as we make the mistake of not doing
our own CRTC commit tracking in the topology_state object.

We already open-code this quite often, and will be iterating through
payloads even more once we've moved all of the payload tracking into the
atomic state. So, let's add a helper for doing this.

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.
Since we're going to be relying on atomic locking for payloads now (and the
MST mgr needs to track CRTCs), pull in the topology state for all modesets
in nv50_msto_atomic_check().

For quite a while we've been carrying around a lot of legacy modesetting
code in the MST helpers that has been rather annoying to keep around,
and very often gets in the way of trying to implement additional
functionality in MST such as fallback link rate retraining, dynamic BPC
management and DSC
This function isn't too confusing if you see the comment around the
call-site for it, but if you don't then it's not at all obvious this is
meant to copy DRM's payload table over to DC's internal state structs.
Seeing this function before finding that comment definitely threw me into a
loop a few
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
There's another kind of situation where we could potentially race with
nonblocking modesets and MST, especially if we were to only use the locking
provided by atomic modesetting:
* Display 1 begins as enabled on DP-1 in SST mode
* Display 1 switches to MST mode, exposes one sink in MST mode
*
We want to start cutting down on all of the places that we use port
validation, so that ports may be removed from the topology as quickly as
possible to minimize the number of errors we run into as a result of being
out of sync with the current topology status. This isn't a very typical
scenario
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
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
Post-NV50, the only kind of encoder you'll find for DP connectors on Nvidia
GPUs are SORs (serial output resources). Because SORs have fixed
associations with their connectors, we can correctly assume that any DP
connector on a nvidia GPU will have exactly one SOR encoder routed to it

Now that we've finally gotten rid of the non-atomic MST users leftover in

64 DRM device nodes is not enough for everyone.
Upgrade it to 512K (which definitely is more than enough).
Additionally - one minor tweak around minor IDR locking.

Operating on drm minor is not done in IRQ context, which means that we

But we can also go further and drop the idr_preload tricks by just using

While we still need to preserve render nodes numbering, there's no need
to reserve the range formerly used for control. Let's repurpose it to be
used by primary and remove control remains from the code entirely.

Because there could be transient votes from other drivers/tz/hyp which
may keep the cx gdsc enabled, we should poll until cx gdsc collapses.
We can use the reset framework to poll for cx gdsc collapse from gpucc
clk driver.
This feature requires support from the platform's gpucc driver.
