drm/i915: Fix mismatch between misplaced vma check and vma insert
When inserting a VMA, we restrict the placement to the low 4G unless the caller opts into using the full range. This was done to allow usersapce the opportunity to transition slowly from a 32b address space, and to avoid breaking inherent 32b assumptions of some commands. However, for insert we limited ourselves to 4G-4K, but on verification we allowed the full 4G. This causes some attempts to bind a new buffer to sporadically fail with -ENOSPC, but at other times be bound successfully. commit |

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.

drm/i915/gem: Flush coherency domains on first set-domain-ioctl
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.

drm/i915/gem: Perform all asynchronous waits prior to marking payload start
The initial breadcrumb marks the transition from context wait and setup into the request payload. We use the marker to determine if the request is merely waiting to begin, or is inside the payload and hung. Forgetting to include a breadcrumb before the user payload would mean we do not reset the guilty user request, and conversely if the initial breadcrumb is too early we blame the user for a problem elsewhere.

drm/i915/gem: Avoid synchronous binds deep within locks
On bxt, we require a VT'd w/a to serialise all GGTT updates with memory
transfers, and use stop_machine() for this purpose. stop_machine() is a
global serialisation barrier and so dangerous to use from within
critical sections, as the stop_machine() will wait for all cpus to enter
the stop_machine callback, and those cpus may be waiting for the
critical section already held.

drm/i915: Exclude low pages (128KiB) of stolen from use
The GPU is trashing the low pages of its reserved memory upon reset. If
we are using this memory for ringbuffers, then we will dutiful resubmit
the trashed rings after the reset causing further resets, and worse. We
must exclude this range from our own use. The value of 128KiB was found
by empirical measurement (and verified now with a selftest) on gen9.

drm/i915: use vmap in i915_gem_object_map
i915_gem_object_map implements fairly low-level vmap functionality in a driver. Split it into two helpers, one for remapping kernel memory which can use vmap, and one for I/O memory that uses vmap_pfn. The only practical difference is that alloc_vm_area prefeaults the vmalloc area PTEs, which doesn't seem to be required here for the kernel memory case (and could be added to vmap using a flag if actually required).

i915: use find_lock_page instead of find_lock_entry
i915 does not want to see value entries. Switch it to use find_lock_page() instead, and remove the export of find_lock_entry(). Move find_lock_entry() and find_get_entry() to mm/internal.h to discourage any future use.

drm/i915: Fix DMA mapped scatterlist lookup
As the previous patch fixed the places where we walk the whole scatterlist for DMA addresses, this patch fixes the random lookup functionality. To achieve this we have to add a second lookup iterator and add a i915_gem_object_get_sg_dma helper, to be used analoguous to existing i915_gem_object_get_sg_dma. Therefore two lookup caches are maintained per object and they are flushed at the same point for simplicity. (Strictly speaking the DMA cache should be flushed from i915_gem_gtt_finish_pages, but today this conincides with unsetting of the pages in general.) Partial VMA view is then fixed to use the new DMA lookup and properly query sg length. v2: * Checkpatch.

lib/scatterlist: Add support in dynamic allocation of SG table from pages
Extend __sg_alloc_table_from_pages to support dynamic allocation of SG table from pages. It should be used by drivers that can't supply all the pages at one time. This function returns the last populated SGE in the table. Users should pass it as an argument to the function from the second call and forward. As before, nents will be equal to the number of populated SGEs (chunks). With this new extension, drivers can benefit the optimization of merging contiguous pages without a need to allocate all pages in advance and hold them in a large buffer. E.g. with the Infiniband driver that allocates a single page for hold the pages. For 1TB memory registration, the temporary buffer would consume only 4KB, instead of 2GB.

drm/i915/gem: Avoid implicit vmap for highmem on x86-32
On 32b, highmem using a finite set of indirect PTE (i.e. vmap) to provide virtual mappings of the high pages. As these are finite, map_new_virtual() must wait for some other kmap() to finish when it runs out. If we map a large number of objects, there is no method for it to tell us to release the mappings, and we deadlock. However, if we make an explicit vmap of the page, that uses a larger vmalloc arena, and also has the ability to tell us to release unwanted mappings. Most importantly, it will fail and propagate an error instead of waiting forever. Fixes: |

drm/i915: Introduce GEM object functions
GEM object functions deprecate several similar callback interfaces in struct drm_driver.

drm/i915/selftest: Create mock_destroy_device
Just some prep work before we rework the lifetime handling, which requires replacing all the drm_dev_put in selftests by something else. v2: Don't go with a static inline, upsets the header tests and separation.

drm/i915/gem: Reduce context termination list iteration guard to RCU
As we now protect the timeline list using RCU, we can drop the timeline->mutex for guarding the list iteration during context close, as we are searching for an inflight request. Any new request will see the context is banned and not be submitted. In doing so, pull the checks for a concurrent submission of the request (notably the i915_request_completed()) under the engine spinlock, to fully serialise with __i915_request_submit()). That is in the case of preempt-to-busy where the request may be completed during the __i915_request_submit(), we need to be careful that we sample the request status after serialising so that we don't miss the request the engine is actually submitting.

drm/i915/gem: Delay tracking the GEM context until it is registered
Avoid exposing a partially constructed context by deferring the list_add() from the initial construction to the end of registration. Otherwise, if we peek into the list of contexts from inside debugfs, we may see the partially constructed context and chase down some dangling incomplete pointers.

drm/i915/gem: Avoid implicit vmap for highmem on x86-32
On 32b, highmem using a finite set of indirect PTE (i.e. vmap) to provide virtual mappings of the high pages. As these are finite, map_new_virtual() must wait for some other kmap() to finish when it runs out. If we map a large number of objects, there is no method for it to tell us to release the mappings, and we deadlock. However, if we make an explicit vmap of the page, that uses a larger vmalloc arena, and also has the ability to tell us to release unwanted mappings. Most importantly, it will fail and propagate an error instead of waiting forever. Fixes: |
