[PATCH v3 0/5] mm/migrate: avoid device private invalidations
The goal for this series is to avoid device private memory TLB
invalidations when migrating a range of addresses from system
memory to device private memory and some of those pages have already
been migrated. The approach taken is to introduce a new mmu notifier
invalidation event type and use that in the device driver to skip
invalidation callbacks from migrate_vma_setup(). The device driver is

[PATCH 0/3] drm/nouveau: extend the lifetime of nouveau_drm
Hi folks,
Currently, when the device is removed (or the driver is unbound) the
nouveau_drm structure de-allocated. However, it's still accessible from
and used by some DRM layer callbacks. For example, file handles can be
closed after the device has been removed (physically or otherwise). This
series converts the Nouveau device structure to be allocated and
de-allocated with the

[PATCH v6 0/6] mm/hmm/test: add self tests for HMM
This series adds new functions to the mmu interval notifier API to
allow device drivers with MMUs to dynamically mirror a process' page
tables based on device faults and invalidation callbacks. The Nouveau
driver is updated to use the extended API and a set of stand alone self
tests is added to help validate and maintain correctness.
The patches are based on linux-5.5.0-rc6 and are for

[PATCH hmm v3 00/14] Consolidate the mmu notifier interval_tree and locking
From: Jason Gunthorpe <jgg at mellanox.com>
8 of the mmu_notifier using drivers (i915_gem, radeon_mn, umem_odp, hfi1,
scif_dma, vhost, gntdev, hmm) drivers are using a common pattern where
they only use invalidate_range_start/end and immediately check the
invalidating range against some driver data structure to tell if the
driver is interested. Half of them use an interval_tree, the others
