drm/ttm: add pgprot handling for RISC-V
The RISC-V Svpbmt privileged extension provides support for overriding
page memory coherency attributes, and, along with vendor extensions like
Xtheadmae, supports pgprot_{writecombine,noncached} on RISC-V.
Adapt the codepath that maps ttm_write_combined to pgprot_writecombine
and ttm_noncached to pgprot_noncached to RISC-V, to allow proper page
access attributes.

drm/ttm: Add safety check for NULL man->bdev in ttm_resource_manager_usage
The `ttm_resource_manager_usage()` function currently assumes `man->bdev` is non-NULL when accessing `man->bdev->lru_lock`. However, in scenarios where the resource manager is not fully initialized (e.g., APU platforms that lack dedicated VRAM, or incomplete manager setup), `man->bdev` may remain NULL. This leads to a NULL pointer dereference when attempting to acquire the `lru_lock`, triggering kernel OOPS. Fix this by adding an explicit safety check for `man->bdev` before accessing its members: - Use `WARN_ON_ONCE(!man->bdev)` to emit a one-time warning (a soft assertion) when `man->bdev` is NULL. This helps catch invalid usage patterns during debugging without breaking production workflows. - Return 0 immediately if `man->bdev` is NULL, as a non-initialized manager cannot have valid resource usage to report.

drm/ttm: rename ttm_bo_put to _fini v3
Give TTM BOs a separate cleanup function.

ttm/bo: add an API to populate a bo before exporting.
While discussing cgroups we noticed a problem where you could export a BO to a dma-buf without having it ever being backed or accounted for. This meant in low memory situations or eventually with cgroups, a lower privledged process might cause the compositor to try and allocate a lot of memory on it's behalf and this could fail. At least make sure the exporter has managed to allocate the RAM at least once before exporting the object. This only applies currently to TTM_PL_SYSTEM objects, because GTT objects get populated on first validate, and VRAM doesn't use TT.

Kemeng Shi does what is claims.
- The 4 patch series "mm: introduce snapshot_page" from Luiz Capitulino

without tripping over the races inherent in operating on the live
pageframe directly.
- The 6 patch series "use per-vma locks for /proc/pid/maps reads" from

Stoakes extends the mremap() selftest in several ways, including adding
more checking of Lorenzo's recently added "permit mremap() move of
multiple VMAs" feature.
- The 22 patch series "selftests/damon/sysfs.py: test all parameters"

drm/ttm: remove ttm_bo_validate_swapout test
The test is quite fragile since it tries to allocate halve available system memory + 1 page. If the system has either not enough memory to make the allocation work with other things running in parallel or to much memory so the allocation fails as to large/invalid the test will fail. Completely remove the test. We already validate swapout on the device level and that test seems to be stable.

drm/ttm: Increase pool shrinker batch target
The default core shrink target of 128 pages (SHRINK_BATCH) is quite low relative to how cheap TTM pool shrinking is, and how the free pages are distributed in page order pools. We can make the target a bit more aggressive by making it roughly the average number of pages across all pools, freeing more of the cached pages every time shrinker core invokes our callback.

drm/ttm: Respect the shrinker core free target
Currently the TTM shrinker aborts shrinking as soon as it frees pages from any of the page order pools and by doing so it can fail to respect the freeing target which was configured by the shrinker core. We use the wording "can fail" because the number of freed pages will depend on the presence of pages in the pools and the order of the pools on the LRU list. For example if there are no free pages in the high order pools the shrinker core may require multiple passes over the TTM shrinker before it will free the default target of 128 pages (assuming there are free pages in the low order pools). This inefficiency can be compounded by the pool LRU where multiple further calls into the TTM shrinker are required to end up looking at the pool with pages. Improve this by never freeing less than the shrinker core has requested.

However with the current implementation casting from a

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() Signed-off-by: Thomas Hellström <thomas.hellstrom@linux.intel.com> Reviewed-by: Matthew Brost <matthew.brost@intel.com> Acked-by: Dave Airlie <airlied@redhat.com> Acked-by: Christian König <christian.koenig@amd.com> Link: https://lore.kernel.org/intel-xe/20250305092220.123405-5-thomas.hellstrom@linux.intel.com |

drm/ttm/pool, drm/ttm/tt: Provide a helper to shrink pages
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.

drm/ttm/pool: Restructure the pool allocation code
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.

drm/ttm: Handle cgroup based eviction in TTM
cgroup resource allocation has to be handled in TTM, so -EAGAIN from cgroups can be converted into -ENOSPC, and the limitcg can be properly evicted in ttm code. When hitting a resource limit through -EAGAIN, the cgroup for which the limit is hit is also returned. This allows eviction to delete only from cgroups which are a subgroup of the current cgroup. The returned CSS is used to determine if eviction is valuable for a given resource, and allows TTM to only target specific resources to lower memory usage.

drm/ttm: Allow direct reclaim to allocate local memory v2
Limiting the allocation of higher order pages to the closest NUMA node and enabling direct memory reclaim provides not only failsafe against situations when memory becomes too much fragmented and the allocator is not able to satisfy the request from the local node but falls back to remote pages (HUGEPAGE) but also offers performance improvement. Accessing remote pages suffers due to bandwidth limitations and could be avoided if memory becomes defragmented and in most cases without using manual compaction. (/proc/sys/vm/compact_memory) Note: On certain distros such as RHEL, the proactive compaction is disabled.

drm/ttm: Use the LRU walker for eviction
Use the LRU walker for eviction. This helps removing a lot of code with weird locking semantics. The functionality is slightly changed so that when trylocked buffer objects are exhausted, we continue to interleave walks with ticket-locks while there is still progress made. The list walks are not restarted in-between evictions. Also provide a separate ttm_bo_evict_first() function for its single user. The context of that user allows sleeping dma_resv locks. v6: - Various cleanups suggested by Matthew Brost. - Fix error return code of ttm_bo_evict_first(). (Matthew Brost) - Fix an error check that was inverted. (Matthew Brost) v7: - Use s64 rather than long (Christian König) - Early ttm_resource_cursor_fini() in ttm_bo_evict_first(). - Simplify check for bo_moved in ttm_bo_evict_first(). (Christian König) - Don't evict pinned bos.

drm/ttm: Use the LRU walker helper for swapping
Rework the TTM swapping to use the LRU walker helper. This helps fixing up the ttm_bo_swapout() interface to be consistent about not requiring any locking. For now mimic the current behaviour of using trylock only. We could be using ticket-locks here but defer that until it's deemed necessary. The TTM swapout functionality is a bit weird anyway since it alternates between memory types without exhausting TTM_PL_SYSTEM first. Intentionally keep pages as the unit of progress since changing that to bytes is an unrelated change that can be done later. v6: - Improve on error code translation in the swapout callback (Matthew Brost). v7: - Use s64 rather than long. - Remove ttm_resource_cursor_fini() since it's no longer used. - Rename ttm_resource_cursor_fini_locked() to ttm_resource_cursor_fini(). - Don't swap out pinned bos.

drm/ttm: Provide a generic LRU walker helper
Provide a generic LRU walker in TTM, in the spirit of drm_gem_lru_scan() but building on the restartable TTM LRU functionality. The LRU walker optionally supports locking objects as part of a ww mutex locking transaction, to mimic to some extent the current functionality in ttm. However any -EDEADLK return is converted to -ENOSPC and then to -ENOMEM before reaching the driver, so that the driver will need to backoff and possibly retry without being able to keep the ticket. v3: - Move the helper to core ttm. - Remove the drm_exec usage from it for now, it will be reintroduced later in the series. v4: - Handle the -EALREADY case if ticketlocking. v6: - Some cleanup and added code comments (Matthew Brost) - Clarified the ticketlock in the commit message (Matthew Brost) v7: - Use s64 rather than long for the target and progress (Christian König) - Update documentation to not encourage using pages as a progress measure.

drm/ttm, drm/amdgpu, drm/xe: Consider hitch moves within bulk sublist moves
To address the problem with hitches moving when bulk move sublists are lru-bumped, register the list cursors with the ttm_lru_bulk_move structure when traversing its list, and when lru-bumping the list, move the cursor hitch to the tail. This also means it's mandatory for drivers to call ttm_lru_bulk_move_init() and ttm_lru_bulk_move_fini() when initializing and finalizing the bulk move structure, so add those calls to the amdgpu- and xe driver. Compared to v1 this is slightly more code but less fragile and hopefully easier to understand. Changes in previous series: - Completely rework the functionality - Avoid a NULL pointer dereference assigning manager->mem_type - Remove some leftover code causing build problems v2: - For hitch bulk tail moves, store the mem_type in the cursor instead of with the manager. v3: - Remove leftover mem_type member from change in v2. v6: - Add some lockdep asserts (Matthew Brost) - Avoid NULL pointer dereference (Matthew Brost) - No need to check bo->resource before dereferencing bo->bulk_move (Matthew Brost) Cc: Christian König <christian.koenig@amd.com> Cc: Somalapuram Amaranath <Amaranath.Somalapuram@amd.com> Cc: Matthew Brost <matthew.brost@intel.com> Cc: <dri-devel@lists.freedesktop.org> Signed-off-by: Thomas Hellström <thomas.hellstrom@linux.intel.com> Reviewed-by: Matthew Brost <matthew.brost@intel.com> Acked-by: Christian König <christian.koenig@amd.com> Link: https://patchwork.freedesktop.org/patch/msgid/20240705153206.68526-5-thomas.hellstrom@linux.intel.com Signed-off-by: Christian König <christian.koenig@amd.com> |

drm/ttm: Use LRU hitches
Have iterators insert themselves into the list they are iterating over using hitch list nodes. Since only the iterator owner can remove these list nodes from the list, it's safe to unlock the list and when continuing, use them as a starting point. Due to the way LRU bumping works in TTM, newly added items will not be missed, and bumped items will be iterated over a second time before reaching the end of the list. The exception is list with bulk move sublists. When bumping a sublist, a hitch that is part of that sublist will also be moved and we might miss items if restarting from it. This will be addressed in a later patch. Changes in previous series: - Updated ttm_resource_cursor_fini() documentation. v2: - Don't reorder ttm_resource_manager_first() and _next(). (Christian König). - Use list_add instead of list_move (Christian König) v3: - Split into two patches, one cleanup, one new functionality (Christian König) - use ttm_resource_cursor_fini_locked() instead of open-coding (Matthew Brost) Cc: Christian König <christian.koenig@amd.com> Cc: Somalapuram Amaranath <Amaranath.Somalapuram@amd.com> Cc: Matthew Brost <matthew.brost@intel.com> Cc: <dri-devel@lists.freedesktop.org> Signed-off-by: Thomas Hellström <thomas.hellstrom@linux.intel.com> Reviewed-by: Matthew Brost <matthew.brost@intel.com> Reviewed-by: Christian König <christian.koenig@amd.com> Link: https://patchwork.freedesktop.org/patch/msgid/20240705153206.68526-4-thomas.hellstrom@linux.intel.com Signed-off-by: Christian König <christian.koenig@amd.com> |

drm/ttm: Slightly clean up LRU list iteration
To make the transition to using lru hitches easier, simplify the ttm_resource_manager_next() interface to only take the cursor and reuse ttm_resource_manager_next() functionality from ttm_resource_manager_first().

drm/ttm: Allow TTM LRU list nodes of different types
To be able to handle list unlocking while traversing the LRU list, we want the iterators not only to point to the next position of the list traversal, but to insert themselves as list nodes at that point to work around the fact that the next node might otherwise disappear from the list while the iterator is pointing to it. These list nodes need to be easily distinguishable from other list nodes so that others traversing the list can skip over them. So declare a struct ttm_lru_item, with a struct list_head member and a type enum. This will slightly increase the size of a struct ttm_resource. Changes in previous series: - Update enum ttm_lru_item_type documentation. v3: - Introduce ttm_lru_first_res_or_null() (Christian König, Thomas Hellström) v5: - Update also the TTM test code (Xe CI).

drm/ttm: Always take the bo delayed cleanup path for imported bos
Bos can be put with multiple unrelated dma-resv locks held. But
imported bos attempt to grab the bo dma-resv during dma-buf detach
that typically happens during cleanup. That leads to lockde splats
similar to the below and a potential ABBA deadlock.
Fix this by always taking the delayed workqueue cleanup path for
imported bos.
Requesting stable fixes from when the Xe driver was introduced,
since its usage of drm_exec and wide vm dma_resvs appear to be
the first reliable trigger of this.

drm/ttm/tests: Let ttm_bo_test consider different ww_mutex implementation.
PREEMPT_RT has a different locking implementation for ww_mutex. The
base mutex of struct ww_mutex is declared as struct WW_MUTEX_BASE. The
latter is defined as `mutex' for non-PREEMPT_RT builds and `rt_mutex'
for PREEMPT_RT builds.
Using mutex_lock() directly on the base mutex in
ttm_bo_reserve_deadlock() leads to compile error on PREEMPT_RT.
The locking-selftest has its own defines to deal with this and it is
probably best to defines the needed one within the test program since
their usefulness is limited outside of well known selftests.
Provide ww_mutex_base_lock() which points to the correct function for
PREEMPT_RT and non-PREEMPT_RT builds.

drm/ttm: stop pooling cached NUMA pages v2
We only pool write combined and uncached allocations because they
require extra overhead on allocation and release.
If we also pool cached NUMA it not only means some extra unnecessary
overhead, but also that under memory pressure it can happen that
pages from the wrong NUMA node enters the pool and are re-used
over and over again.
This can lead to performance reduction after running into memory
pressure.
v2: restructure and cleanup the code a bit from the internal hack to
test this.

drm/ttm: improve idle/busy handling v5
Previously we would never try to move a BO into the preferred placements
when it ever landed in a busy placement since those were considered
compatible.
Rework the whole handling and finally unify the idle and busy handling.
ttm_bo_validate() is now responsible to try idle placement first and then
use the busy placement if that didn't worked.
Drawback is that we now always try the idle placement first for each
validation which might cause some additional CPU overhead on overcommit.
v2: fix kerneldoc warning and coding style
v3: take care of XE as well
v4: keep the ttm_bo_mem_space functionality as it is for now, only add
new handling for ttm_bo_validate as suggested by Thomas

drm/ttm: Make sure the mapped tt pages are decrypted when needed
Some drivers require the mapped tt pages to be decrypted. In an ideal
world this would have been handled by the dma layer, but the TTM page
fault handling would have to be rewritten to able to do that.
A side-effect of the TTM page fault handling is using a dma allocation
per order (via ttm_pool_alloc_page) which makes it impossible to just
trivially use dma_mmap_attrs. As a result ttm has to be very careful
about trying to make its pgprot for the mapped tt pages match what
the dma layer thinks it is. At the ttm layer it's possible to
deduce the requirement to have tt pages decrypted by checking
whether coherent dma allocations have been requested and the system
is running with confidential computing technologies.
This approach isn't ideal but keeping TTM matching DMAs expectations
for the page properties is in general fragile, unfortunately proper
fix would require a rewrite of TTM's page fault handling.
Fixes vmwgfx with SEV enabled.
v2: Explicitly include cc_platform.h
v3: Use CC_ATTR_GUEST_MEM_ENCRYPT instead of CC_ATTR_MEM_ENCRYPT to
limit the scope to guests and log when memory decryption is enabled.

drm/ttm: replace busy placement with flags v6
Instead of a list of separate busy placement add flags which indicate
that a placement should only be used when there is room or if we need to
evict.
v2: add missing TTM_PL_FLAG_IDLE for i915
v3: fix auto build test ERROR on drm-tip/drm-tip
v4: fix some typos pointed out by checkpatch
v5: cleanup some rebase problems with VMWGFX
v6: implement some missing VMWGFX functionality pointed out by Zack,
rename the flags as suggested by Michel, rebase on drm-tip and
adjust XE as well
