When swapping in, or under memory pressure ttm_tt_populate() may sleep
for a substantiable amount of time. Allow interrupts during the sleep.
This will also allow us to inject -EINTR errors during swapin in upcoming
patches.
Also avoid returning VM_FAULT_OOM, since that will confuse the core
mm, making it print out a confused message and retrying the fault.
Return VM_FAULT_SIGBUS also under OOM conditions.

When swapping out, we will split multi-order pages both in order to
move them to the swap-cache and to be able to return memory to the
swap cache as soon as possible on a page-by-page basis.
Reduce the page max order to the system PMD size, as we can then be nicer
to the system and avoid splitting gigantic pages.
Looking forward to when we might be able to swap out PMD size folios
without splitting, this will also be a benefit.
v2:
- Include all orders up to the PMD size (Christian König)
v3:
- Avoid compilation errors for architectures with special PFN_SHIFTs

When hitting an error, the error path forgot to unmap dma mappings and
could call set_pages_wb() on already uncached pages.
Fix this by introducing a common ttm_pool_free_range() function that
does the right thing.

- Simplify that common function (Christian König)
v3:
- Rename that common function to ttm_pool_free_range() (Christian König)

The LRU mechanism may look up a resource in the process of being removed
from an object. The locking rules here are a bit unclear but it looks
currently like res->bo assignment is protected by the LRU lock, whereas
bo->resource is protected by the object lock, while *clearing* of
bo->resource is also protected by the LRU lock. This means that if
we check that bo->resource points to the LRU resource under the LRU
lock we should be safe.
So perform that check before deciding to swap out a bo. That avoids
dereferencing a NULL bo->resource in ttm_bo_swapout().

The ttm BO now initially has NULL bo->resource, and leaves the driver
the handle that. However it looks like we forgot to handle that for
ttm_bo_move_memcpy() users, like with vram-gem, since it just silently
returns zero. This seems to then trigger warnings like:
WARNING: CPU: 0 PID: 1 at drivers/gpu/drm/drm_gem_vram_helper.c:255 drm_gem_vram_offset (??:?)
Fix this by calling move_null() if the new resource is TTM_PL_SYSTEM,
otherwise do the multi-hop sequence to ensure can safely call into
ttm_bo_move_memcpy(), since it might also need to clear the memory.
This should give the same behaviour as before.
While we are here let's also treat calling ttm_bo_move_memcpy() with
NULL bo->resource as programmer error, where expectation is that upper
layers should now handle it.

In the next few patches, when initially creating a ttm BO, the
bo->resource is NULL, and the driver is then expected to handle the
initial dummy move. However, if this is created as a system resource
the first ttm_tt we create will always have the clear value set to
false. Previously the initial ttm_tt would be created in
ttm_bo_validate() with the clear parameter always set to true.

Fixes: d91c411c744b ("drm/ttm: update bulk move object of ghost BO")
|
|
[Why]
Ghost BO is released with non-empty bulk move object. There is a
warning trace:
WARNING: CPU: 19 PID: 1582 at ttm/ttm_bo.c:366 ttm_bo_release+0x2e1/0x2f0 [amdttm]
Call Trace:
amddma_resv_reserve_fences+0x10d/0x1f0 [amdkcl]
amdttm_bo_put+0x28/0x30 [amdttm]
amdttm_bo_move_accel_cleanup+0x126/0x200 [amdttm]
amdgpu_bo_move+0x1a8/0x770 [amdgpu]
ttm_bo_handle_move_mem+0xb0/0x140 [amdttm]
amdttm_bo_validate+0xbf/0x100 [amdttm]
[How]
The resource of ghost BO should be moved to LRU directly, instead of
using bulk move. The bulk move object of ghost BO should set to NULL
before function ttm_bo_move_to_lru_tail_unlocked.
v2: set bulk move to NULL manually if no resource associated with ghost BO

Pull MM updates from Andrew Morton:
"Most of the MM queue. A few things are still pending.
Liam's maple tree rework didn't make it. This has resulted in a few
other minor patch series being held over for next time.
Multi-gen LRU still isn't merged as we were waiting for mapletree to
stabilize. The current plan is to merge MGLRU into -mm soon and to
later reintroduce mapletree, with a view to hopefully getting both
into 6.1-rc1.
Summary:
- The usual batches of cleanups from Baoquan He, Muchun Song, Miaohe
Lin, Yang Shi, Anshuman Khandual and Mike Rapoport
- Some kmemleak fixes from Patrick Wang and Waiman Long
- DAMON updates from SeongJae Park
- memcg debug/visibility work from Roman Gushchin
- vmalloc speedup from Uladzislau Rezki
- more folio conversion work from Matthew Wilcox
- enhancements for coherent device memory mapping from Alex Sierra
- addition of shared pages tracking and CoW support for fsdax, from
Shiyang Ruan
- hugetlb optimizations from Mike Kravetz
- Mel Gorman has contributed some pagealloc changes to improve
latency and realtime behaviour.
- mprotect soft-dirty checking has been improved by Peter Xu
- Many other singleton patches all over the place"

Rename ttm_bo_init to ttm_bo_init_validate since that better matches
what the function is actually doing.
Remove the unused size parameter, move the function's kerneldoc to the
implementation and cleanup the whole error handling.

Currently shrinkers are anonymous objects. For debugging purposes they
can be identified by count/scan function names, but it's not always
useful: e.g. for superblock's shrinkers it's nice to have at least an
idea of to which superblock the shrinker belongs.
This commit adds names to shrinkers. register_shrinker() and
prealloc_shrinker() functions are extended to take a format and arguments
to master a name.
In some cases it's not possible to determine a good name at the time when
a shrinker is allocated. For such cases shrinker_debugfs_rename() is
provided.
The expected format is:
<subsystem>-<shrinker_type>[:<instance>]-<id>
For some shrinkers an instance can be encoded as (MAJOR:MINOR) pair.
After this change the shrinker debugfs directory looks like:
$ cd /sys/kernel/debug/shrinker/
$ ls
