[PATCH v15 0/9] TTM shrinker helpers and xe buffer object shrinker

[Thomas Hellström]

This series implements TTM shrinker / eviction helpers and an xe bo
shrinker. It builds on a previous series, *and obsoletes that one*.

now addressed, and this version also implements shmem objects for backup
rather than direct swap-cache insertions, which was used in the previuos
series. It turns out that with per-page backup / shrinking, shmem objects
appears to work just as well as direct swap-cache insertions with the
added benefit that was introduced in the previous TTM shrinker series to
avoid running out of swap entries isn't really needed.

The series earlier consisted of a LRU traversal part and the current part.
The LRU traversal part is merged, but is still mentioned in the history
below.

Patch 1 balances ttm_resource_cursor_fini() with an init function. It
makes patch 5 more straightforward.

Patch 2 introduces a backup implemententaion.

Patch 3 reworks the structure of ttm_pool_alloc in preparation for patch 4.

Patch 4 introduces functionality in the ttm_pool code for page-by-page shrinking
and recovery. It avoids having to temporarily allocate a huge amount of
memory to be able to shrink a buffer object. It also introduces the
possibility to immediately write-back pages if needed.

Patch 5 Adds a simple error injection to the above code to help increase
test coverage.

Patch 6 Implements a macro for LRU iteration.

Patch 7 Introduces driver-facing helpers for shrinking.

Patch 8 Implements the xe bo shrinker.

Patch 9 Increases (removes) the XE_PL_TT watermark.

v2:
- Squash obsolete revision history in the patch commit messages.
- Fix a couple of review comments by Christian
- Don't store the mem_type in the TTM managers but in the
  resource cursor.
- Rename introduced TTM *back_up* function names to *backup*
- Add ttm pool recovery fault injection.
- Shrinker xe kunit test
- Various bugfixes

v3:
- Address some review comments from Matthew Brost and Christian König.
- Use the restartable LRU walk for TTM swapping and eviction.
- Provide a POC drm_exec locking implementation for exhaustive
  eviction. (Christian König).

v4:
- Remove the RFC exhaustive eviction part. While the path to exhaustive
  eviction is pretty clear and demonstrated in v3, there is still some
  drm_exec work that needs to be agreed and implemented.
- Add shrinker power management. On some hw we need to wake when shrinking.
- Fix the lru walker helper for -EALREADY errors.
- Add drm/xe: Increase the XE_PL_TT watermark.

v5:
- Update also TTM kunit tests
- Handle ghost- and zombie objects in the shrinker.
- A couple of compile- and UAF fixes reported by Kernel Build Robot and
  Dan Carpenter.

v6:
- Address review comments from Matthew Brost on the
  restartable LRU traversal path.

v7:
- Split out TTM restartable LRU traversal path and merge that.
- Adapt the review comments on that series.

v8:
- Address review comments from Matthew Brost as detailed in the
  respective patches.

v9:
- Rebase and fix compilation errors

v10:
- Use a LRU iteration macro rather than a function with a callback.
- Rebasing and cleanups
- Address some additional review comments from Matt Brost.
- Drop the shrinker selftest. It was already merged as a swapout
  self-test.

v11:
- Move more core interaction to additional TTM helpers.
- Don't back up without __GFP_FS, and don't start writeback without __GFP_IO.
- Rebase.

v12:
- Fix an indentation flaw.
- Rebase

v13:
- Remove the backup base-class, and use direct calls for ttm_backup
  (Christian König).
- Rebase on the ttm_backup changes.
- Move shrunken bos from the LRU list to the unevictable list.
- Provide an accessor function with sanity checks to set the
- ttm_tt::backup field.
- Update documentation.

v14:
- Update documentation of ttm_backup_bytes_avail().
- Work around converting between struct file * and struct ttm-backup *.
- Don't set up backup for imported buffers.

v15:
- ttm_backup return value change. (Christian König)
- ttm_pool restore/alloc implementation rework (Christian König)
- Documentation update.
- Remove cond_resched (Christian König)

[PATCH v15 2/9] drm/ttm: Provide a shmem backup implementation

[Thomas Hellström]

Provide a standalone shmem backup implementation.
Given the ttm_backup interface, this could
later on be extended to providing other backup
implementation than shmem, with one use-case being
GPU swapout to a user-provided fd.

v5:
- Fix a UAF. (kernel test robot, Dan Carptenter)
v6:
- Rename ttm_backup_shmem_copy_page() function argument
  (Matthew Brost)
- Add some missing documentation
v8:
- Use folio_file_page to get to the page we want to writeback
  instead of using the first page of the folio.
v13:
- Remove the base class abstraction (Christian König)
- Include ttm_backup_bytes_avail().
v14:
- Fix kerneldoc for ttm_backup_bytes_avail() (0-day)
- Work around casting of __randomize_layout struct pointer (0-day)
v15:
- Return negative error code from ttm_backup_backup_page()
  (Christian König)
- Doc fixes. (Christian König).

[PATCH v15 3/9] drm/ttm/pool: Restructure the pool allocation code

[Thomas Hellström]

Simplify the pool allocation code somewhat by merging loop arguments
used by multiple functions together in a struct and simplifying the
loop. Also add documentation.
This hopefully makes the behaviour of the allocation loop
simplier to understand, but above all paves the way for upcoming
restore-while-allocating functionality.

There are no functional changes, but the "allow_pools" bool
introduced to keep current functionality could be removed as a
follow up, which would enable using write-back cached pools when
allocating memory for other caching modes, rather than to resort
to allocating from the system directly.

v15:
- Introduce this patch to simplify the upcoming patch that introduces
  restore while allocating.

[PATCH v15 4/9] drm/ttm/pool, drm/ttm/tt: Provide a helper to shrink pages

[Thomas Hellström]

Provide a helper to shrink ttm_tt page-vectors on a per-page
basis. A ttm_backup backend could then in theory get away with
allocating a single temporary page for each struct ttm_tt.

This is accomplished by splitting larger pages before trying to
back them up.

In the future we could allow ttm_backup to handle backing up
large pages as well, but currently there's no benefit in
doing that, since the shmem backup backend would have to
split those anyway to avoid allocating too much temporary
memory, and if the backend instead inserts pages into the
swap-cache, those are split on reclaim by the core.

Due to potential backup- and recover errors, allow partially swapped
out struct ttm_tt's, although mark them as swapped out stopping them
from being swapped out a second time. More details in the ttm_pool.c
DOC section.

v2:
- A couple of cleanups and error fixes in ttm_pool_back_up_tt.
- s/back_up/backup/
- Add a writeback parameter to the exported interface.
v8:
- Use a struct for flags for readability (Matt Brost)
- Address misc other review comments (Matt Brost)
v9:
- Update the kerneldoc for the ttm_tt::backup field.
v10:
- Rebase.
v13:
- Rebase on ttm_backup interface change. Update kerneldoc.
- Rebase and adjust ttm_tt_is_swapped().
v15:
- Rebase on ttm_backup return value change.
- Rebase on previous restructuring of ttm_pool_alloc()
- Rework the ttm_pool backup interface (Christian König)
- Remove cond_resched() (Christian König)
- Get rid of the need to allocate an intermediate page array
  when restoring a multi-order page (Christian König)
- Update documentation.

[PATCH v15 5/9] drm/ttm: Use fault-injection to test error paths

[Thomas Hellström]

Use fault-injection to test partial TTM swapout and interrupted swapin.
Return -EINTR for swapin to test the callers ability to handle and
restart the swapin, and on swapout perform a partial swapout to test that
the swapin and release_shrunken functionality.

v8:
- Use the core fault-injection system.
v9:
- Fix compliation failure for !CONFIG_FAULT_INJECTION

[PATCH v15 6/9] drm/ttm: Add a macro to perform LRU iteration

[Thomas Hellström]

Following the design direction communicated here:

https://lore.kernel.org/linux-mm/b7491378-defd-4f1c-31e2-29e4c77e2d67@amd.com/T/#ma918844aa8a6efe8768fdcda0c6590d5c93850c9

Export a LRU walker for driver shrinker use. The walker
initially supports only trylocking, since that's the
method used by shrinkes. The walker makes use of
scoped_guard() to allow exiting from the LRU walk loop
without performing any explicit unlocking or
cleanup.

v8:
- Split out from another patch.
- Use a struct for bool arguments to increase readability (Matt Brost).
- Unmap user-space cpu-mappings before shrinking pages.
- Explain non-fatal error codes (Matt Brost)

v10:
- Instead of using the existing helper, Wrap the interface inside out and
  provide a loop to de-midlayer things the LRU iteration (Christian König).
- Removing the R-B by Matt Brost since the patch was significantly changed.

v11:
- Split the patch up to include just the LRU walk helper.

v12:
- Indent after scoped_guard() (Matt Brost)

v15:
- Adapt to new definition of scoped_guard()

[PATCH v15 7/9] drm/ttm: Add helpers for shrinking

[Thomas Hellström]

Add a number of helpers for shrinking that access core TTM and
core MM functionality in a way that make them unsuitable for
driver open-coding.

v11:
- New patch (split off from previous) and additional helpers.
v13:
- Adapt to ttm_backup interface change.
- Take resource off LRU when backed up.

[PATCH v15 8/9] drm/xe: Add a shrinker for xe bos

[Thomas Hellström]

Rather than relying on the TTM watermark accounting add a shrinker
for xe_bos in TT or system memory.

Leverage the newly added TTM per-page shrinking and shmem backup
support.

Although xe doesn't fully support WONTNEED (purgeable) bos yet,
introduce and add shrinker support for purgeable ttm_tts.

v2:
- Cleanups bugfixes and a KUNIT shrinker test.
- Add writeback support, and activate if kswapd.
v3:
- Move the try_shrink() helper to core TTM.
- Minor cleanups.
v4:
- Add runtime pm for the shrinker. Shrinking may require an active
  device for CCS metadata copying.
v5:
- Separately purge ghost- and zombie objects in the shrinker.
- Fix a format specifier - type inconsistency. (Kernel test robot).
v7:
- s/long/s64/ (Christian König)
- s/sofar/progress/ (Matt Brost)
v8:
- Rebase on Xe KUNIT update.
- Add content verifying to the shrinker kunit test.
- Split out TTM changes to a separate patch.
- Get rid of multiple bool arguments for clarity (Matt Brost)
- Avoid an error pointer dereference (Matt Brost)
- Avoid an integer overflow (Matt Auld)
- Address misc review comments by Matt Brost.
v9:
- Fix a compliation error.
- Rebase.
v10:
- Update to new LRU walk interface.
- Rework ghost-, zombie and purged object shrinking.
- Rebase.
v11:
- Use additional TTM helpers.
- Honor __GFP_FS and __GFP_IO
- Rebase.
v13:
- Use ttm_tt_setup_backup().
v14:
- Don't set up backup on imported bos.
v15:
- Rebase on backup interface changes.

[PATCH v15 9/9] drm/xe: Increase the XE_PL_TT watermark

[Thomas Hellström]

The XE_PL_TT watermark was set to 50% of system memory.
The idea behind that was unclear since the net effect is that
TT memory will be evicted to TTM_PL_SYSTEM memory if that
watermark is exceeded, requiring PPGTT rebinds and dma
remapping. But there is no similar watermark for TTM_PL_1SYSTEM
memory.

The TTM functionality that tries to swap out system memory to
shmem objects if a 50% limit of total system memory is reached
is orthogonal to this, and with the shrinker added, it's no
longer in effect.

Replace the 50% TTM_PL_TT limit with a 100% limit, in effect
allowing all graphics memory to be bound to the device unless it
has been swapped out by the shrinker.

Re: [PATCH v15 0/9] TTM shrinker helpers and xe buffer object shrinker

[Christian König]

Any objections that I push patch #1 and #3 to drm-misc-next?

They are general cleanups anyway and this way we have them out of the way.

Regards,
Christian.

Re: [PATCH v15 0/9] TTM shrinker helpers and xe buffer object shrinker

Please do. I have to rewrite the cover letter but that's not a big
deal. Also perhaps consider adding a patch to remove the "allow_pools"
functionality.

Also re-raising the question if there is a way we can make TTM
development scale a bit better, with a team of trusted reviewers? 
I am currently working under the assumption that you want to at least
ack everything that goes into TTM?

Thanks,
Thomas
