Allow encoders to customize their hotplug processing by moving the intel_hpd_irq_event() code into an encoder hotplug vfunc. Currently only SDVO needs this to re-enable hotplug signalling in the SDVO chip. We'll use this same hook for DP/HDMI link management later. Reviewed-by:

Previously, we would spin waiting for all waiters to wake up and notice their request had completed before we would reset the seqno upon wraparound. However, we can mark their waits as complete and wake them up directly using the existing machinery for handling the flushing of missed wakeups when idling. Suggested-by:

Since commit fd10e2ce ("drm/i915/breadcrumbs: Ignore unsubmitted signalers"), we cancel the signaler when retiring the request and so upon wraparound, where we wait for all requests to be retired, we no longer need to spin waiting for the signaling thread to release its references to the in-flight requests, and so we can assert that the signaler is idle.

When parking the engines and their breadcrumbs, if we have waiters left then they missed their wakeup. Verify that each waiter's seqno did complete. Signed-off-by:

Chris Wilson authored
The goal here is to try and reduce the latency of signaling additional requests following the wakeup from interrupt by reducing the list of to-be-signaled requests from an rbtree to a sorted linked list. The original choice of using an rbtree was to facilitate random insertions of request into the signaler while maintaining a sorted list. However, if we assume that most new requests are added when they are submitted, we see those new requests in execution order making a insertion sort fast, and the reduction in overhead of each signaler iteration significant. Since commit 56299fb7 ("drm/i915: Signal first fence from irq handler if complete"), we signal most fences directly from notify_ring() in the interrupt handler greatly reducing the amount of work that actually needs to be done by the signaler kthread. All the thread is then required to do is operate as the bottom-half, cleaning up after the interrupt handler and preparing the next waiter. This includes signaling all later completed fences in a saturated system, but on a mostly idle system we only have to rebuild the wait rbtree in time for the next interrupt. With this de-emphasis of the signaler's role, we want to rejig it's datastructures to reduce the amount of work we require to both setup the signal tree and maintain it on every interrupt.

During reset/wedging, we have to clean up the requests on the timeline and flush the pending interrupt state. Currently, we are abusing the irq disabling of the timeline spinlock to protect the irq state in conjunction to the engine's timeline requests, but this is accidental and conflates the spinlock with the irq state. A baffling state of affairs for the reader. Instead, explicitly disable irqs over the critical section, and separate modifying the irq state from the timeline's requests. Suggested-by:

Chris Wilson authored
Although this state (execlists->active and engine->irq_posted) itself is not protected by the engine->timeline spinlock, it does conveniently ensure that irqs are disabled. We can use this to protect our manipulation of the state and so ensure that the next IRQ to arrive sees consistent state and (hopefully) ignores the reset engine. Suggested-by:

The race is horrible as it results from calling set-wedged on active HW (the GPU reset failed) and as such we need to be careful as the HW state changes beneath us. Fortunately, it's the same scary conditions as affect normal reset, so we can reuse the same machinery to disable state tracking as we clobber it.

Enabling FBC on a plane having a Y-offset that isn't divisible by 4 may cause pipe FIFO underruns and flickers, so disable FBC on such a config. I tried the followings to work around the issue: - enable each HW work around in ILK_DPFC_CHICKEN - disable each compression algorithm in ILK_DPFC_CONTROL - disable low-power watermarks None of the above got rid of the problem. I haven't found this issue in the Bspec/WA database either. Besides the igt testcase below (yet to be merged) an easy way to reproduce the issue is to enable a plane with FBC and a plane Y-offset not aligned to 4 and then just enable/disable FBC in a loop, keeping the plane enabled. I could trigger the problem on BXT/GLK/SKL/CNL, so assume for now that it's only present on GEN9 and GEN10. v2: (Ville) - Run the test/apply the WA on CNL as well. - Use IS_GEN() instead of INTEL_GEN(). - Fix spelling.

We're seeing on CI that some contexts don't have the programmed OA period timer that directs the OA unit on how often to write reports. The issue is that we're not holding the drm lock from when we edit the context images down to when we set the exclusive_stream variable.

Localize link rate arrays by moving them to the functions where they're used. Further clarify the distinction between source and sink capabilities. Split pre and post Haswell arrays, and get rid of the array size arithmetics. Use a direct rate value in the paranoia case of no common rates find.

While it seems totally unlikely that any system would mix a cpu/north aux channel with a pch/south port (or vice versa) we should still consult intel_dp->aux_ch rather than encoder->port when figuring out which clock is actually used by the aux ch. Signed-off-by:

Although we protect the request itself, we don't lock inside intel_engine_dump() and so the request maybe retired as we peek into it. One consequence is that the request->ctx may be freed before we dereference it, leading to a use-after-free. Replace the hw_id we are peeking from inside request->ctx with the request->fence.context, with which we can still track from which context the request originated (although to tie to HW reports requires a little more legwork, but is good enough to follow the GEM traces).

On pre-HSW we have dedicated hardware for the RGB limited range handling, and so we don't want to compress with the CSC matrix. Toss in a FIXME about gamma LUT vs. limited range using the CSC.
