The commit 213e08ad ("drm/i915/bxt: add bxt dsi gpio element support") enables GPIO support for Broxton based platforms. While using that API we might get into troubles in the future, because we can't rely on label name in the driver since vendor firmware might provide any GPIO pin there, e.g. "reset", and even mark it in _DSD (in which case the request will fail). To avoid inconsistency and potential issues we have two options: a) generate GPIO ACPI mapping table and supply it via acpi_dev_add_driver_gpios(), or b) just pass NULL as connection ID. The b) approach is much simpler and would work since the driver relies on GPIO indices only. Moreover, the _CRS fallback mechanism, when requesting GPIO, has been made stricter, and supplying non-NULL connection ID when neither _DSD, nor GPIO ACPI mapping is present, is making request fail.

In a synchronous setup, we may retire the last request before we complete allocating the next request. As the last request is retired, we queue a timer to mark the device as idle, and promptly have to execute ad cancel that timer once we complete allocating the request and need to keep the device awake. If we rearrange the mark_busy() to occur before we retire the previous request, we can skip this ping-pong. v2: Joonas pointed out that unreserve_seqno() was now doing more than doing seqno handling and should be renamed to reflect its wider purpose. That also highlighted the new asymmetry with reserve_seqno(), so fixup that and rename both to [un]reserve_engine(). Signed-off-by:

This was the competing idea long ago, but it was only with the rewrite of the idr as an radixtree and using the radixtree directly ourselves, along with the realisation that we can store the vma directly in the radixtree and only need a list for the reverse mapping, that made the patch performant enough to displace using a hashtable. Though the vma ht is fast and doesn't require any extra allocation (as we can embed the node inside the vma), it does require a thread for resizing and serialization and will have the occasional slow lookup. That is hairy enough to investigate alternatives and favour them if equivalent in peak performance. One advantage of allocating an indirection entry is that we can support a single shared bo between many clients, something that was done on a first-come first-serve basis for shared GGTT vma previously. To offset the extra allocations, we create yet another kmem_cache for them. Signed-off-by:

Since the introduction of being able to perform a lockless lookup of an object (i915_gem_object_get_rcu() in fbbd37b3 ("drm/i915: Move object release to a freelist + worker") we no longer need to split the object/vma lookup into 3 phases and so combine them into a much simpler single loop.

When userspace is doing most of the work, avoiding relocs (using NO_RELOC) and opting out of implicit synchronisation (using ASYNC), we still spend a lot of time processing the arrays in execbuf, even though we now should have nothing to do most of the time. One issue that becomes readily apparent in profiling anv is that iterating over the large execobj[] is unfriendly to the loop prefetchers of the CPU and it much prefers iterating over a pair of arrays rather than one big array. v2: Clear vma[] on construction to handle errors during vma lookup Signed-off-by:

Forcewake is not affected by the engine reset on gen6+. Indeed the reason why we added intel_uncore_forcewake_reset() to gen6_reset_engines() was to keep the bookkeeping intact because the reset did not touch the forcewake bit (yet we cancelled the forcewake consumers)! This was done in commit 521198a2: Author: Mika Kuoppala <mika.kuoppala@linux.intel.com> Date: Fri Aug 23 16:52:30 2013 +0300 drm/i915: sanitize forcewake registers on reset In reset we try to restore the forcewake state to pre reset state, using forcewake_count. The reset doesn't seem to clear the forcewake bits so we get warn on forcewake ack register not clearing. That futzing of the forcewake bookkeeping was dropped in commit 0294ae7b ("drm/i915: Consolidate forcewake resetting to a single function"), but it did not make the realisation that the remaining intel_uncore_forcewake_reset() was redundant. The new danger with using intel_uncore_forcewake_reset() with per-engine resets is that the driver and hw are still in an active state as we perform the reset. We may be using the forcewake to read protected registers elsewhere and those results may be clobbered by the concurrent dropping of forcewake. Reported-by:

For a bunch of reasons[1] I've decided to step down as maintainer and let some other folks enjoy the reputation and hang out in the spotlight. Jani is going to stick around with his expertise in kms and having done the fixes flow for a long time now. Joonas will join and bring in his knowledge on all things GEM. Rodrigo has been less visible because he's been doing tons of work taking care of the internal branch, and it'd be good to have more continuity between these two worlds also on the maintainer side. 1: They all boil down to: This is going to happen sooner or later anyway, we have a great team, with the process improvements over the last few years things work rather well, now is as good as any time to do this. With that change I'll have more time for other aspects of the stack development than maintainership.
