2020-11-13drm/i915/gvt: return error when failing to take the module referenceXiongfeng Wang1-1/+3
When we fail to take the module reference, we go to the 'undo*' branch and return. But the returned variable 'ret' has been set as zero by the above code. Change 'ret' to '-ENODEV' in this situation.

2020-11-13drm/i915/gem: Pull phys pread/pwrite implementations to the backendChris Wilson2-26/+55
Move the specialised interactions with the physical GEM object from the pread/pwrite ioctl handler into the phys backend. Currently, if one is able to exhaust the entire aperture and then try to pwrite into an object not backed by struct page, we accidentally invoked the phys pwrite handler on a non-phys object; calamitous.

2020-11-04drm/i915/gt: Use the local HWSP offset during submissionChris Wilson3-16/+31
We wrap the timeline on construction of the next request, but there may still be requests in flight that have not yet finalized the breadcrumb. (The breadcrumb is delayed as we need engine-local offsets, and for the virtual engine that is not known until execution.) As such, by the time we write to the timeline's HWSP offset it may have changed, and we should use the value we preserved in the request instead. Though the window is small and infrequent (at full flow we can expect a timeline's seqno to wrap once every 30 minutes), the impact of writing the old seqno into the new HWSP is severe: the old requests are never completed, and the new requests are completed before they are even submitted.

2020-11-04drm/i915/gem: Flush coherency domains on first set-domain-ioctlChris Wilson1-15/+13
Avoid skipping what appears to be a no-op set-domain-ioctl if the cache coherency state is inconsistent with our target domain. This also has the utility of using the population of the pages to validate the backing store. The danger in skipping the first set-domain is leaving the cache inconsistent and submitting stale data, or worse leaving the clean data in the cache and not flushing it to the GPU. The impact should be small as it requires a no-op set-domain as the very first ioctl in a particular sequence not found in typical userspace.

The job queue needs to be cleaned up using vc4_gem_destroy, but it's not used consistently (vc4_drv's bind calls it in its error path, but doesn't in unbind), and we can make that automatic through a managed action. Let's remove the requirement to call vc4_gem_destroy. Fixes: d5b1a78a772f ("drm/vc4: Add support for drawing 3D frames.")
