Subject: [RFC PATCH v2 0/8] Support DEVICE_GENERIC memory in migrate_vma_*
Date: Mon, 7 Jun 2021 15:42:18 -0500 [thread overview]
Message-ID: <20210607204226.7743-1-alex.sierra@amd.com> (raw)
v1:
https://lore.kernel.org/linux-mm/20210529064022.GB15834@lst.de/T/
v2:
This patch series version has merged "[RFC PATCH v3 0/2]
mm: remove extra ZONE_DEVICE struct page refcount" patch series made by
Ralph Campbell. It also applies at the top of these series, our changes
to support device generic type in migration_vma helpers.
This has been tested in systems with device memory that has coherent
access by CPU.
Also addresses the following feedback made in v1:
- Isolate in one patch kernel/resource.c modification, based
on Christoph's feedback.
- Add helpers check for generic and private type to avoid
duplicated long lines.
I like to provide an overview of what each of the patches does in a series:
Patches 1-2: Rebased Ralph Campbell's ZONE_DEVICE page refcounting patches
Patch 3: Export lookup_resource
Patches 4-5: AMDGPU driver changes to register and use DEVICE_GENERIC memory
Patches 6-8: Handle DEVICE_GENERIC memory in migration helpers
Alex Sierra (6):
kernel: resource: lookup_resource as exported symbol
drm/amdkfd: add SPM support for SVM
drm/amdkfd: generic type as sys mem on migration to ram
include/linux/mm.h: helpers to check zone device generic type
mm: add generic type support to migrate_vma helpers
mm: call pgmap->ops->page_free for DEVICE_GENERIC pages
Ralph Campbell (2):
ext4/xfs: add page refcount helper
mm: remove extra ZONE_DEVICE struct page refcount
