2020-09-07drm/i915/gt: Switch to object allocations for page directoriesChris Wilson1-17/+20
The GEM object is grossly overweight for the practicality of tracking large numbers of individual pages, yet it is currently our only abstraction for tracking DMA allocations. Since those allocations need to be reserved upfront before an operation, and that we need to break away from simple system memory, we need to ditch using plain struct page wrappers. In the process, we drop the WC mapping as we ended up clflushing everything anyway due to various issues across a wider range of platforms. Though in a future step, we need to drop the kmap_atomic approach which suggests we need to pre-map all the pages and keep them mapped. v2: Verify our large scratch page is suitably DMA aligned; and manually clear the scratch since we are allocating plain struct pages full of prior content.

2020-09-07drm/i915: Preallocate stashes for vma page-directoriesChris Wilson1-33/+27
We need to make the DMA allocations used for page directories to be performed up front so that we can include those allocations in our memory reservation pass. The downside is that we have to assume the worst case, even before we know the final layout, and always allocate enough page directories for this object, even when there will be overlap. This unfortunately can be quite expensive, especially as we have to clear/reset the page directories and DMA pages, but it should only be required during early phases of a workload when new objects are being discovered, or after memory/eviction pressure when we need to rebind. Once we reach steady state, the objects should not be moved and we no longer need to preallocating the pages tables. It should be noted that the lifetime for the page directories DMA is more or less decoupled from individual fences as they will be shared across objects across timelines. v2: Only allocate enough PD space for the PTE we may use, we do not need to allocate PD that will be left as scratch. v3: Store the shift unto the first PD level to encapsulate the different PTE counts for gen6/gen8.

2020-05-28drm/i915/gt: Remove local entries from GGTT on suspendChris Wilson1-2/+21
Across suspend/resume, we clear the entire GGTT and rebuild from scratch. In particular, we want to only preserve the global entries for use by the HW, and delay reinstating the local binds until required by the user. This means that we can evict any local binds in the global GTT, saving any time in preserving their state, as they will be rebound on demand.

2020-02-28drm/i915/ggtt: do not set bits 1-11 in gen12 ptesDaniele Ceraolo Spurio1-3/+10
On TGL, bits 2-4 in the GGTT PTE are not ignored anymore and are instead used for some extra VT-d capabilities. We don't (yet?) have support for those capabilities, but, given that we shared the pte_encode function betweed GGTT and PPGTT, we still set those bits to the PPGTT PPAT values. The DMA engine gets very confused when those bits are set while the iommu is enabled, leading to errors. E.g. when loading the GuC we get: [ 9.796218] DMAR: DRHD: handling fault status reg 2 [ 9.796235] DMAR: [DMA Write] Request device [00:02.0] PASID ffffffff fault addr 0 [fault reason 02] Present bit in context entry is clear [ 9.899215] [drm:intel_guc_fw_upload [i915]] *ERROR* GuC firmware signature verification failed To fix this, just have dedicated gen8_pte_encode function per type of gtt. Also, explicitly set vm->pte_encode for gen8_ppgtt, even if we don't use it, to make sure we don't accidentally assign it to the GGTT one, like we do for gen6_ppgtt, in case we need it in the future.

On Braswell and Broxton (also known as Valleyview and Apollolake), we need to serialise updates of the GGTT using the big stop_machine() hammer. This has the side effect of appearing to lockdep as a possible reclaim (since it uses the cpuhp mutex and that is tainted by per-cpu allocations). However, we want to use vm->mutex (including ggtt->mutex) from within the shrinker and so must avoid such possible taints. For this purpose, we introduced the asynchronous vma binding and we can apply it to the PIN_GLOBAL so long as take care to add the necessary waits for the worker afterwards.

2020-01-10drm/i915/gt: Hold rpm wakeref before taking ggtt->vm.mutexChris Wilson1-23/+5
We need to hold the runtime-pm wakeref to update the global PTEs (as they exist behind a PCI BAR). However, some systems invoke ACPI during runtime resume and so require allocations, which is verboten inside the vm->mutex. Ergo, we must not use intel_runtime_pm_get() inside the mutex, but lift the call outside.

2020-01-10drm/i915: Start chopping up the GPU error captureChris Wilson1-0/+3
In the near future, we will want to start a GPU error capture from a new context, from inside the softirq region of a forced preemption. To do so requires us to break up the monolithic error capture to provide new entry points with finer control; in particular focusing on one engine/gt, and being able to compose an error state from little pieces of HW capture.

2020-01-10drm/i915/gt: Skip trying to unbind in restore_ggtt_mappingsChris Wilson1-5/+2
Currently we first to try to unbind the VMA (and lazily rebind on next use) as an optimisation during restore_ggtt_mappings. Ideally, the only objects in the GGTT upon resume are the pinned kernel objects which can't be unbound and need to be restored. As the unbind interferes with the plan to mark those objects as active for error capture, forgo the optimisation.
