This series adds support for transparent huge page migration to migrate_vma_*() and adds nouveau SVM and HMM selftests as consumers. Earlier versions were posted previously [1] and [2]. The patches apply cleanly to the linux-mm 5.10.0-rc2 tree. There are a lot of other THP patches being posted. I don't think there are any semantic conflicts but there may be some merge conflicts depending on

This series adds support for transparent huge page migration to migrate_vma_*() and adds nouveau SVM and HMM selftests as consumers. An earlier version was posted previously [1]. This version now supports splitting a THP midway in the migration process which led to a number of changes. The patches apply cleanly to the current linux-mm tree. Since there are a couple of patches in linux-mm from Dan

These patches apply to linux-5.8.0-rc1. Patches 1-3 should probably go into 5.8, the others can be queued for 5.9. Patches 4-6 improve the HMM self tests. Patch 7-8 prepare nouveau for the meat of this series which adds support and testing for compound page mapping of system memory (patches 9-11) and compound page migration to device private memory (patches 12-16). Since these changes are split

Another revision of this patchset critical for GK20A to operate. Previous attempts were exclusively using either TTM's regular page allocator or the DMA API one. Both have their advantages and drawbacks: the page allocator is fast but requires explicit synchronization on non-coherent architectures, whereas the DMA allocator always returns coherent memory, but is also slower, creates a

In the trace below, swiotlb_alloc() is called with __GFP_NOWARN, it ors attrs with DMA_ATTR_NO_WARN and passes it to swiotlb_alloc_buffer(), which does NOT pass it on to swiotlb_tbl_map_single(), leading to an ever repeating warning that the caller of swiotlb_alloc() explicitly asked to be squelched. Pass the caller's request for silence onward. Xorg-3170 [006] .... 963.866098:

There is currently a mixture of octal and symbolic permissions uses in files in drivers/gpu/drm and one file in drivers/gpu. There are ~270 existing octal uses and ~115 S_<FOO> uses. Convert all the S_<FOO> symbolic permissions to their octal equivalents as using octal and not symbolic permissions is preferred by many as more readable. see: https://lkml.org/lkml/2016/8/2/1945 Done

Unfortunately AGP is still to widely used as we could just drop support for using its GART. Not using the AGP GART also doesn't mean a loss in functionality since drivers will just fallback to the driver specific PCI GART. For now just deprecate the code and don't enable the AGP GART in TTM even when general AGP support is available. Please comment, Christian.

I''ve noticed with xen-unstable on my quad-core x dual-thread (that''s 8 processors to xen), the boot info spewed for all the C-state/P-state stuff quickly fills the xm dmesg buffer and I lose some of the early-in-boot lines. Do we really need to know "reg.{space_id,bit_width,bit_offset,access_size, address}" and all that other info? Even if so, is there a more compact

Well I think we rejected that multiple times now. At least I find the symbolic permissions easier to read and I absolutely don't see any reason why we should only use one form. Christian.

The jazzdma ops implement support for a very basic IOMMU. Thus we really should not use the dma-direct code that takes physical address limits into account. This survived through the great MIPS DMA ops cleanup mostly because I was lazy, but now it is time to fully split the implementations.

Even when core AGP support is compiled in Radeon and Nouveau can also work with the PCI GART. The AGP support was notorious unstable and hard to maintain, so deprecate it for now and only enable it if there is a good reason to do so.

Hello, Last December I wrote to the list asking about obnoxiously long freezes when using Windows 7's "explorer" to browse a samba repository. While Windows was frozen, samba's log was filling with smbd_dirptr_get_entry messages -- one for each file in a particular directory. Since I had some directories with 10,000 files, this was a slow process. Amusingly, I was not
