On seqno rollover, we need to allocate ourselves a new cacheline. This might incur grabbing a new page and pinning it into the GGTT, with some rather unfortunate lockdep implications. To avoid a mutex, and more specifically pinning in the GGTT from inside the kernel context being used to flush the GGTT in emergencies, we will likely need to lift the next-cacheline allocation to a pre-reservation.

Inside the intel_timeline_get_seqno(), we currently track the retirement of the old cachelines by listening to the new request. This requires that the new request is ready to be used and so requires a minimum bit of initialisation prior to getting the new seqno.

The workarounds are a common "feature" across gens and submission mechanisms and we already call the other WA related functions from common engine ones (<setup/cleanup>_common), so it makes sense to do the same with WA application. Medium-term, This will help us reduce the duplication once the GuC resume function is added, but short term it will also allow us to use the workaround lists for pre-gen8 engine workarounds.

To enable non-persistent contexts, we require a means of cancelling any inflight work from that context. This is first done "gracefully" by using preemption to kick the active context off the engine, and then forcefully by resetting the engine if it is active. If we are unable to reset the engine to remove hostile userspace, we should not allow userspace to opt into using non-persistent contexts. If the per-engine reset fails, we still do a full GPU reset, but that is rare and usually indicative of much deeper issues. The damage is already done. However, the goal of the interface to allow long running compute jobs without causing collateral damage elsewhere, and if we are unable to support that we should make that known by not providing the interface (and falsely pretending we can).

Let's add a copy of the active_pipes bitmask into the cdclk_state. While this is duplicating a bit of information we may already have elsewhere, I think it's worth it to decopule the cdclk stuff from whatever else wants to use that bitmask. Also we want to get rid of all the old ad-hoc global state which is what the current bitmask is, so this removes one obstacle. The one extra thing we have to remember is write locking the cdclk state whenever the bitmask changes.

Now that we have the more formal global state thing let's use if for memory bandwidth tracking. No real difference to the current private object usage since we already tried to avoid taking the single serializing lock needlessly. But since we're going to roll the global state out to more things probably a good idea to unify the approaches a bit.

Our current global state handling is pretty ad-hoc. Let's try to make it better by imitating the standard drm core private object approach. The reason why we don't want to directly use the private objects is locking; Each private object has its own lock so if we introduce any global private objects we get serialized by that single lock across all pipes. The global state apporoach instead uses a read/write lock type of approach where each individual crtc lock counts as a read lock, and grabbing all the crtc locks allows one write access.

I want to have a higher level cdclk state object so let's rename the current lower level thing to cdclk_config (because I lack imagination).

intel_cdclk_needs_cd2x_update() is named rather confusingly. We don't have to do a cd2x update, rather we are allowed to do one (as opposed to a full PLL reprogramming with its heavy handed modeset). So let's rename the function to intel_cdclk_can_cd2x_update().

Move the min_cdclk[] and min_voltage_level[] arrays under the rest of the cdclk state.

Move the initial setup of state->{cdclk,min_cdclk[],min_voltage_level[]} into intel_modeset_calc_cdclk(), and we'll move the counterparts into intel_cdclk_swap_state(). This encapsulates the cdclk state much better.

The linetime watermarks really have very little in common with the plane watermarks. It looks to be cleaner to simply track them in the crtc_state and program them from the normal modeset/fastset paths. The only dark cloud comes from the fact that the register is still supposedly single buffered. So in theory it might still need some form of two stage programming. Note that even though HSW/BDWhave two stage programming we never computed any special intermediate values for the linetime watermarks, and on SKL+ we don't even have the two stage stuff plugged in since everything else is double buffered. So let's assume it's all fine and continue doing what we've been doing. Actually on HSW/BDW the value should not even change without a full modeset since it doesn't account for pfit downscaling. Thus only fastboot might be affected. But on SKL+ the pfit scaling factor is take into consideration so the value may change during any fastset. As a bonus we'll plug this thing into the state checker/dump now. v2: Rebase due to bigjoiner prep v2: Only compute ips linetime for IPS capable pipes. Bspec says the register values is ignored for other pipes, but in fact it can't even be written so the state checker becomes unhappy if we don't compute it as zero.
