* drm/i915: Use maximum write flush for pwrite_gttChris Wilson2019-07-181-2/+3
| | | | | | | | | | | | | | As recently disovered by forcing big-core (!llc) machines to use the GTT paths, we need our full GTT write flush before manipulating the GTT PTE or else the writes may be directed to the wrong page.

| | | | | | | | | | | | | | | | | | | | The "misc" terminology doesn't clearly explain what we intend to cover in this phase. The only thing we used ot do in there apart from FW fetch was initializing the log workqueue, with the latter being required only in the very rare case where we enable the log relay. As we no longer create our own workqueue, piggybacking on the system_highpri_wq instead, we can rename the function to clarify that they only fetch/release the blobs. v2: only create log wq when needed (Michal), reword commit msg accordingly v3: after rebase the wq is gone, reword commit msg accordingly Signed-off-by: Daniele Ceraolo Spurio <daniele.ceraolospurio@intel.com> Cc: Michal Wajdeczko <michal.wajdeczko@intel.com> Reviewed-by: Chris Wilson <chris@chris-wilson.co.uk> Reviewed-by: Michal Wajdeczko <michal.wajdeczko@intel.com> Link: https://patchwork.freedesktop.org/patch/msgid/20190713100016.8026-2-chris@chris-wilson.co.uk Signed-off-by: Chris Wilson <chris@chris-wilson.co.uk>

* drm/i915/gem: Free pages before rcu-freeing the objectChris Wilson2019-07-031-2/+6
| | | | | | | | | | | | | | | | | | | | | | | As we have dropped the final reference to the object, we do not need to wait until after the rcu grace period to drop its pages. We still require struct_mutex to completely unbind the object to release the pages, so we still need a free-worker to manage that from process context. By scheduling the release of pages before waiting for the rcu should mean that we are not trapping those pages from beyond the reach of the shrinker. v2: Pass along the request to skip if the vma is busy to the underlying unbind routine, to avoid checking the reservation underneath the i915->mm.obj_lock which may be used from inside irq context. v3: Flip the bit for unbinding while active, for later convenience.

* drm/i915: Keep contexts pinned until after the next kernel context switchChris Wilson2019-06-141-4/+0
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | We need to keep the context image pinned in memory until after the GPU has finished writing into it. Since it continues to write as we signal the final breadcrumb, we need to keep it pinned until the request after it is complete. Currently we know the order in which requests execute on each engine, and so to remove that presumption we need to identify a request/context-switch we know must occur after our completion. Any request queued after the signal must imply a context switch, for simplicity we use a fresh request from the kernel context. The sequence of operations for keeping the context pinned until saved is: - On context activation, we preallocate a node for each physical engine the context may operate on. This is to avoid allocations during unpinning, which may be from inside FS_RECLAIM context (aka the shrinker) - On context deactivation on retirement of the last active request (which is before we know the context has been saved), we add the preallocated node onto a barrier list on each engine - On engine idling, we emit a switch to kernel context. When this switch completes, we know that all previous contexts must have been saved, and so on retiring this request we can finally unpin all the contexts that were marked as deactivated prior to the switch. We can enhance this in future by flushing all the idle contexts on a regular heartbeat pulse of a switch to kernel context, which will also be used to check for hung engines. v2: intel_context_active_acquire/_release Signed-off-by: Chris Wilson <chris@chris-wilson.co.uk> Cc: Mika Kuoppala <mika.kuoppala@linux.intel.com> Reviewed-by: Mika Kuoppala <mika.kuoppala@linux.intel.com> Link: https://patchwork.freedesktop.org/patch/msgid/20190614164606.15633-1-chris@chris-wilson.co.uk

| | | | | | | | | | | | | We cannot allow ourselves to wait on the GPU while holding any lock as we may need to reset the GPU. While there is not an explicit lock between the two operations, lockdep cannot detect the dependency. So let's tell lockdep about the wait/reset dependency with an explicit lockmap.

* drm/i915: Report all objects with allocated pages to the shrinkerChris Wilson2019-05-311-11/+12
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Currently, we try to report to the shrinker the precise number of objects (pages) that are available to be reaped at this moment. This requires searching all objects with allocated pages to see if they fulfill the search criteria, and this count is performed quite frequently. (The shrinker tries to free ~128 pages on each invocation, before which we count all the objects; counting takes longer than unbinding the objects!) If we take the pragmatic view that with sufficient desire, all objects are eventually reapable (they become inactive, or no longer used as framebuffer etc), we can simply return the count of pinned pages maintained during get_pages/put_pages rather than walk the lists every time. The downside is that we may (slightly) over-report the number of objects/pages we could shrink and so penalize ourselves by shrinking more than required. This is mitigated by keeping the order in which we shrink objects such that we avoid penalizing active and frequently used objects, and if memory is so tight that we need to free them we would need to anyway. v2: Only expose shrinkable objects to the shrinker; a small reduction in not considering stolen and foreign objects. v3: Restore the tracking from a "backup" copy from before the gem/ split Signed-off-by: Chris Wilson <chris@chris-wilson.co.uk> Cc: Joonas Lahtinen <joonas.lahtinen@linux.intel.com> Cc: Matthew Auld <matthew.auld@intel.com> Reviewed-by: Matthew Auld <matthew.auld@intel.com> Link: https://patchwork.freedesktop.org/patch/msgid/20190530203500.26272-2-chris@chris-wilson.co.uk
* drm/i915: Track the purgeable objects on a separate eviction listChris Wilson2019-05-311-2/+18
| | | | | | | | | | | | | | | | | | | | Currently the purgeable objects, I915_MADV_DONTNEED, are mixed in the normal bound/unbound lists. Every shrinker pass starts with an attempt to purge from this set of unneeded objects, which entails us doing a walk over both lists looking for any candidates. If there are none, and since we are shrinking we can reasonably assume that the lists are full!, this becomes a very slow futile walk. If we separate out the purgeable objects into own list, this search then becomes its own phase that is preferentially handled during shrinking. Instead the cost becomes that we then need to filter the purgeable list if we want to distinguish between bound and unbound objects.

| | | | | | | | | | | | | | | | | | In order to support driver hot unbind, some cleanup operations, now performed on PCI driver remove, must be called later, after all device file descriptors are closed. Split out those operations from the tail of pci_driver.remove() callback and put them into drm_driver.release() which is called as soon as all references to the driver are put. As a result, those cleanups will be now run on last drm_dev_put(), either still called from pci_driver.remove() if all device file descriptors are already closed, or on last drm_release() file operation.
