Since unifying ringbuffer/execlist submission to use engine->pin_context, we ensure that the intel_ring is available before we start constructing the request. We can therefore move the assignment of the request->ring to the central i915_gem_request_alloc() and not require it in every engine->request_alloc() callback. Another small step towards simplification (of the core, but at a cost of handling error pointers in less important callers of engine->pin_context). v2: Rearrange a few branches to reduce impact of PTR_ERR() on gcc's code generation.

Now that everything is in place let's register a PCM device for each port of the display engine. This will make it possible to actually output audio to multiple displays at the same time.

vlv_display_irq_postinstall() enables the LPE audio interrupts regardless of whether the LPE audio irq chip has masked/unmasked them. Also the irqchip masking/unmasking doesn't consider the state of the display power well or the device, and hence just leads to dmesg spew when it tries to access the hardware while it's powered down. If the current way works, then we don't need to do anything in the mask/unmask hooks. If it doesn't work, well, then we'd need to properly track whether the irqchip has masked/unmasked the interrupts when we enable display interrupts. And the mask/unmask hooks would need to check whether display interrupts are even enabled before frobbing with he registers. So let's just assume the current way works and neuter the mask/unmask hooks. Also clean up vlv_display_irq_postinstall() a bit and stop it from trying to unmask/enable the LPE C interrupt on VLV since it doesn't exist.

Not calling pm_runtime_enable() means that runtime PM can't be enabled at all via sysfs. So we definitely need to call it from somewhere. Calling it from the driver seems like a bad idea because it would have to be paired with a pm_runtime_disable() at driver unload time, otherwise the core gets upset. Also if there's no LPE audio driver loaded then we couldn't runtime suspend i915 either. So it looks like a better plan is to call it from i915 when we register the platform device. That seems to match how pci generally does things. I cargo culted the pm_runtime_forbid() and pm_runtime_set_active() calls from pci as well. The exposed runtime PM API is massive an thorougly misleading, so I don't actually know if this is how you're supposed to use the API or not. But it seems to work. I can now runtime suspend i915 again with or without the LPE audio driver loaded, and reloading the LPE audio driver also seems to work. Note that powertop won't auto-tune runtime PM for platform devices, which is a little annoying. So I'm not sure that leaving runtime PM in "on" mode by default is the best choice here. But I've left it like that for now at least. Also remove the comment about there not being much benefit from LPE audio runtime PM. Not allowing runtime PM blocks i915 runtime PM, which will also block s0ix, and that could have a measurable impact on power consumption.

Track the latest fence waited upon on each context, and only add a new asynchronous wait if the new fence is more recent than the recorded fence for that context. This requires us to filter out unordered timelines, which are noted by DMA_FENCE_NO_CONTEXT. However, in the absence of a universal identifier, we have to use our own i915->mm.unordered_timeline token. v2: Throw around the debug crutches v3: Inline the likely case of the pre-allocation cache being full. v4: Drop the pre-allocation support, we can lose the most recent fence in case of allocation failure -- it just means we may emit more awaits than strictly necessary but will not break. v5: Trim allocation size for leaf nodes, they only need an array of u32 not pointers. v6: Create mock_timeline to tidy selftest writing v7: s/intel_timeline_sync_get/intel_timeline_sync_is_later/ (Tvrtko) v8: Prune the stale sync points when we idle. v9: Include a small benchmark in the kselftests v10: Separate the idr implementation into its own compartment.

Currently we filter out repeated use of the same timeline in the low level i915_gem_request_await_request(), after having added the dependency on the old request. However, we can lift this to i915_gem_request_await_dma_fence() (before the dependency is added) using the observation that requests along the same timeline are explicitly ordered via i915_add_request (along with the dependencies).

By first unwrapping an incoming fence-array into its child fences, we can simplify the internal branching, and so avoid triggering a potential bug in the next patch when not squashing the child fences on the same timeline. It will also have the advantage of keeping the (top-level) fence arrays out of any fence/timeline caching since these are unordered timelines but with a random context id. Signed-off-by:

2 clflushes on two different objects are not ordered, and so do not belong to the same timeline (context). Either we use a unique context for each, or we reserve a special global context to mean unordered. Ideally, we would reserve 0 to mean unordered (DMA_FENCE_NO_CONTEXT) to have the same semantics everywhere. Signed-off-by:

Replace the handcrafter loop when checking for fifo slots with atomic wait for. This brings this wait in line with the other waits on register access. We also get a readable timeout constraint, so make it to fail after 10ms. Chris suggested that we should fail silently as the fifo debug handler, now attached to unclaimed mmio handling, will take care of the possible errors at later stage. Note that the decision to wait was changed so that we avoid allocating the first reserved entry. Nor do we reduce the count if we fail the wait, removing the possiblity to wrap the count if the hw fifo returned zero. v2: remove unclaimed check on timeout (Chris) v3: use void return (Chris) References: https://bugs.freedesktop.org/show_bug.cgi?id=100247Signed-off-by:

So far we only allowed for 1 retry and just failed the query - and thereby high precision vblank timestamping - if we did not get a reasonable result, as such a failure wasn't considered all too horrible. There are a few NVidia gpu models out there which may need a bit more than 1 retry to get a successful query result under some conditions. Since Linux 4.4 the update code for vblank counter and timestamp in drm_update_vblank_count() changed so that the implementation assumes that high precision vblank timestamping of a kms driver either consistently succeeds or consistently fails for a given video mode and encoder/connector combo. Iow. switching from success to fail or vice versa on a modeset or connector change is ok, but spurious temporary failure for a given setup can confuse the core code and potentially cause bad miscounting of vblanks and confusion or hangs in userspace clients which rely on vblank stuff, e.g., desktop compositors. Therefore change the max retry count to a larger number - more than any gpu so far is known to need to succeed, but still low enough so that these queries which do also happen in vblank interrupt are still fast enough to be not disastrously long if something would go badly wrong with them. As such sporadic retries only happen seldom even on affected gpu's, this could mean a vblank irq could take a few dozen microseconds longer every few hours of uptime -- better than a desktop compositor randomly hanging every couple of hours or days of uptime in a hard to reproduce manner.
