I forgot to actually move two functions mem_cgroup_node_nr_lru_pages() and mem_cgroup_nr_lru_pages() into mm/memcontrol-v1.c, so that they remain in mm/memcontrol.c and their commented out duplicated versions in mm/memcontrol-v1.c. Andrew, can you, please, squash it into the original commit? I checked that the rest of mm-unstable tree can be rebased automatically without any merge conflicts.

Therefore, we want to introduce per-order mTHP split counters to monitor the frequency of mTHP splits.

The change log says: The basic idea is to free higher order pages instead of going through every single one. Also, some unnecessary atomic operations are done away with and replaced with non-atomic equivalents, and prefetching is done where it helps the most. For a more in-depth discusion of this patch, please see the linux-ia64 archives (topic is "free bootmem feedback patch"). So there are several changes improve the bootmem freeing, in which the most basic idea is freeing higher order pages. And as Matthew says, "Itanium CPUs of this era had no prefetchers." I did 10 round bootup tests before and after this change, the data doesn't prove prefetchw() help speeding up bootmem freeing. The sum of the 10 round bootmem freeing time after prefetchw() removal even 5.2% faster than before.

I started with this one, which is unifying hugetlb into generic pagewalk, instead of having its hugetlb_entry entries. Which means that pmd_entry/pte_entry(for cont-pte) entries will also deal with hugetlb vmas as well, and so will new pud_entry entries since hugetlb can be pud mapped (devm pages as well but we seem not to care about those with the exception of hmm code). The outcome is this RFC. Before you continue, let me clarify certain points: This patchset is not yet finished, as there are things that 1) need more thought, 2) are still broken (like the hmm bits as I am clueless about that) 3) some paths have not been tested at all. The things I tested were: - memory-failure - smaps/numa_maps/pagemap (the latter only for pud/pmd, not cont-{pmd,ptes} - mempolicy on arm64 (for 64KB and 32M hugetlb pages) and on x86_64 (for 2MB and 1GB hugetlb pages). More tests need to be conducted, and I plan to borrow a pp64le machine to also carry out some tests there, but for now this is what my bandwith allowed me to do. I am well aware that there are two things that might scare people, one being the number of patches, and the other being the amount of code added. For the former, I will by no means ask anyone to review 45 patches, but since this patchset touches isolated paths (damon, mincore, hmm, task_mmu, memory-failure, mempolicy), I will point out some people that might be able to help me out with those different bits: - Miaohe for memory-failure bits - David for task_mmu bits - SeongJae Park for damon bits - Jerome for hmm bits - feel freel to join for the rest I think that that might be a good approach, and instead of having to review 45 patches, one has only to review at most 5 or 6. For the latter, there is an explanation: hugetlb operates on ptes (although it allocates puds/pmds and the operations work on that level too), which means that now that we will handle PUD/PMD-mapped hugetlb with {pud,pmd}_* operations, we need to introduce quite a few functions that do not exist yet and we need from now onwards. Although I am sending this out, this is not a "rfc ready material", as I said there are still things that need to be improved/fixed/tested, but I wanted to make it public nevertheless so we can gather some constructive feedback that helps us moving in the right direction and to also widen the discussions. So take this more of a "Hey, let me show what I am doing and call me out on things you consider wrong".

Normally if a page is present and in CMA area, pin_user_pages_remote() will migrate the page from CMA area to non-CMA area because of FOLL_LONGTERM flag. But the current code will cause the migration failure due to unexpected page refcounts, and eventually cause the virtual machine fail to start. If a page is added in LRU batch, its refcount increases one, remove the page from LRU batch decreases one. Page migration requires the page is not referenced by others except page mapping. Before migrating a page, we should try to drain the page from LRU batch in case the page is in it, however, folio_test_lru() is not sufficient to tell whether the page is in LRU batch or not, if the page is in LRU batch, the migration will fail. To solve the problem above, we modify the logic of adding to LRU batch. Before adding a page to LRU batch, we clear the LRU flag of the page so that we can check whether the page is in LRU batch by folio_test_lru(page). It's quite valuable, because likely we don't want to blindly drain the LRU batch simply because there is some unexpected reference on a page, as described above. This change makes the LRU flag of a page invisible for longer, which may impact some programs. For example, as long as a page is on a LRU batch, we cannot isolate it, and we cannot check if it's an LRU page. Further, a page can now only be on exactly one LRU batch. This doesn't seem to matter much, because a new page is allocated from buddy and added to the lru batch, or be isolated, it's LRU flag may also be invisible for a long time.

This design is hard to maintain. Thus, this patch is proposed to reduce the possible code paths by consolidating different initialization patches into one. The earlier discussion with Jonathan and Ying is listed here: https://lore.kernel.org/lkml/20240405150244.00004b49@Huawei.com/ If we want to put these two initializations together, they must be placed together in the later function. Because only at that time, the HMAT information will be ready, adist between nodes can be calculated, and memory tiering can be established based on the adist. So we position the initialization at memory_tier_init() to the memory_tier_late_init() call. Moreover, it's natural to keep memory_tier initialization in drivers at device_initcall() level. If we simply move the set_node_memory_tier() from memory_tier_init() to late_initcall(), it will result in HMAT not registering the mt_adistance_algorithm callback function, because set_node_memory_tier() is not performed during the memory tiering initialization phase, leading to a lack of correct default_dram information. Therefore, we introduced a nodemask to pass the information of the default DRAM nodes. The reason for not choosing to reuse default_dram_type->nodes is that it is not clean enough. So in the end, we use a __initdata variable, which is a variable that is released once initialization is complete, including both CPU and memory nodes for HMAT to iterate through. This patchset is based on commits ("memory tier: create CPUless memory tiers after obtaining HMAT info") and ("memory tier: dax/kmem: introduce an abstract layer for finding, allocating, and putting memory types"): [0/2] https://lkml.kernel.org/r/20240405000707.2670063-1-horenchuang@bytedance.com [1/2] https://lkml.kernel.org/r/20240405000707.2670063-2-horenchuang@bytedance.com [1/2] https://lkml.kernel.org/r/20240405000707.2670063-3-horenchuang@bytedance.com Signed-off-by: Ho-Ren (Jack) Chuang Suggested-by: Jonathan Cameron --- - v3: * Combine the cover letter and the patch. * Remove extern default_dram_type * Remove __initdata in a extern variable * Roll back coding style, fix comment description - v2: Thanks to Huang, Ying's and Andrew's comments * Add a cover letter * Add Suggested-by: Jonathan Cameron * Add get/put_online_mems() protection in memory_tier_late_init() * If memtype is set, skip initializing its node * Remove redundant code/comments or rewrite code in a cleaner manner * https://lore.kernel.org/all/20240628060925.303309-1-horen.chuang@linux.dev/ - v1: * https://lore.kernel.org/all/20240621044833.3953055-1-horen.chuang@linux.dev/ - Open to discussion: * Should we use `continue` or `break` if set_node_memory_tier() fails in memory_tier_late_init()?

There are 2 problems with this; 1. this is not what was implemented by the code and 2. this is not the desirable behavior. Desirable behavior is for khugepaged to be enabled when any PMD-sized THP is enabled, anon or file. (Note that file THP is still controlled by the top-level control so we must always consider that, as well as the PMD-size mTHP control for anon). khugepaged only supports collapsing to PMD-sized THP so there is no value in enabling it when PMD-sized THP is disabled. So let's change the code and documentation to reflect this policy. Further, per-size enabled control modification events were not previously forwarded to khugepaged to give it an opportunity to start or stop. Consequently the following was resulting in khugepaged eroneously not being activated: echo never > /sys/kernel/mm/transparent_hugepage/enabled echo always > /sys/kernel/mm/transparent_hugepage/hugepages-2048kB/enabled Signed-off-by: Ryan Roberts Fixes: 3485b88390b0 ("mm: thp: introduce multi-size THP sysfs interface") Closes: https://lore.kernel.org/linux-mm/7a0bbe69-1e3d-4263-b206-da007791a5c4@redhat.com/ Cc: stable@vger.kernel.org --- Hi All, Applies on top of mm-unstable from a couple of days ago (9bb8753acdd8). No regressions observed in mm selftests. When fixing this I also noticed that khugepaged doesn't get (and never has been) activated/deactivated by `shmem_enabled=`. I've concluded that this is definitely a (separate) bug. But I'm waiting for the conclusion of the conversation at [2] before fixing, so will send separately. Changes since v1 [1] ==================== - hugepage_pmd_enabled() now considers CONFIG_READ_ONLY_THP_FOR_FS as part of decision; means that for kernels without this config, khugepaged will not be started when only the top-level control is enabled.

The context and motivation can be seen in cover letter of the RFC v1 [0]. We also recorded a talk about this effort at LPC [1], if someone would like more context on this effort. A lot of emphasis has been put on testing using kdevops, starting with an XFS baseline [3]. The testing has been split into regression and progression. Regression testing: In regression testing, we ran the whole test suite to check for regressions on existing profiles due to the page cache changes. I also ran split_huge_page_test selftest on XFS filesystem to check for huge page splits in min order chunks is done correctly. No regressions were found with these patches added on top. Progression testing: For progression testing, we tested for 8k, 16k, 32k and 64k block sizes. To compare it with existing support, an ARM VM with 64k base page system (without our patches) was used as a reference to check for actual failures due to LBS support in a 4k base page size system. There are some tests that assumes block size < page size that needs to be fixed. We have a tree with fixes for xfstests [4], most of the changes have been posted already, and only a few minor changes need to be posted. Already part of these changes has been upstreamed to fstests, and new tests have also been written and are out for review, namely for mmap zeroing-around corner cases, compaction and fsstress races on mm, and stress testing folio truncation on file mapped folios. No new failures were found with the LBS support. We've done some preliminary performance tests with fio on XFS on 4k block size against pmem and NVMe with buffered IO and Direct IO on vanilla Vs + these patches applied, and detected no regressions. We also wrote an eBPF tool called blkalgn [5] to see if IO sent to the device is aligned and at least filesystem block size in length. For those who want this in a git tree we have this up on a kdevops large-block-minorder-for-next-v9 tag [6].

Moreover, the swap code already supports for swapping out large folio without split, and large folio swap-in[3] series is queued into mm-unstable branch. Hence this patch set also supports the large folio swap-out and swap-in for shmem. Note: this series is targeted for v6.12. Please help to review. Thanks. Functional testing ================== I use the latest mm-unstable branch to test with reverting Chris's "mm: swap: mTHP swap allocator base on swap cluster order" series which can cause some problems (Hugh also reported in [4]). Machine environment: 32 Arm cores, 120G memory and 50G swap device. 1. Run xfstests suite to test tmpfs filesystem, and I did not catch any regressions with this patch set. FSTYP=tmpfs export TEST_DIR=/mnt/tempfs_mnt export TEST_DEV=/mnt/tempfs_mnt export SCRATCH_MNT=/mnt/scratchdir export SCRATCH_DEV=/mnt/scratchdir 2. Run all mm selftests in tools/testing/selftests/mm/, and no regressions found. 3. I also wrote several shmem swap test cases, including shmem splitting, shmem swapout, shmem swapin, swapoff during shmem swapout, shmem reclaim, shmem swapin replacement, etc. I tested these cases under 4K and 64K shmem folio sizes with a swap device, and shmem swap functionality works well on my machine.

With this series, P2PDMA memory mmaped into userspace (ie. only NVMe CMBs, at the moment) can then be used with ibv_reg_mr() (or similar) interfaces. This can be tested by passing a sysfs p2pmem allocator to the --mmap flag of the perftest tools. This requires addressing two issues: * Stop exporting kernfs VMAs with page_mkwrite, which is incompatible with FOLL_LONGTERM and is redudant since the default fault code has the same behavior as kernfs_vma_page_mkwrite() (i.e., call file_update_time()). * Remove the restriction on FOLL_LONGTREM with FOLL_PCI_P2PDMA which was initially put in place due to excessive caution with assuming P2PDMA would have similar problems to fsdax with unmap_mapping_range(). Seeing P2PDMA only uses unmap_mapping_range() on device unbind and immediately waits for all page reference counts to go to zero after calling it, it is actually believed to be safe from reuse and user access faults. See [1] for more discussion. This was tested using a Mellanox ConnectX-6 SmartNIC (MT28908 Family), using the mlx5_core driver, as well as an NVMe CMB.

Doing so while a MAP_FIXED mapping is executing means that a reader may see a gap in the vma tree that should never logically exist - and does not when using the mmap lock in read mode. The temporal gap exists because mmap_region() calls munmap() prior to installing the new mapping. This patch set stops rcu readers from seeing the temporal gap by splitting up the munmap() function into two parts. The first part prepares the vma tree for modifications by doing the necessary splits and tracks the vmas marked for removal in a side tree. The second part completes the munmapping of the vmas after the vma tree has been overwritten (either by a MAP_FIXED replacement vma or by a NULL in the munmap() case). Please note that rcu walkers will still be able to see a temporary state of split vmas that may be in the process of being removed, but the temporal gap will not be exposed. vma_start_write() are called on both parts of the split vma, so this state is detectable.

More importantly this functionality represents an internal implementation detail of memory management and should not be exposed outside of mm/ itself. This patch series isolates core VMA manipulation functionality into its own file, mm/vma.c, and provides an API to the rest of the mm code in mm/vma.h. Importantly, it also carefully implements mm/vma_internal.h, which specifies which headers need to be imported by vma.c, leading to the very useful property that vma.c depends only on mm/vma.h and mm/vma_internal.h. This means we can then re-implement vma_internal.h in userland, adding shims for kernel mechanisms as required, allowing us to unit test internal VMA functionality. This testing is useful as opposed to an e.g. kunit implementation as this way we can avoid all external kernel side-effects while testing, run tests VERY quickly, and iterate on and debug problems quickly. Excitingly this opens the door to, in the future, recreating precise problems observed in production in userland and very quickly debugging problems that might otherwise be very difficult to reproduce. This patch series takes advantage of existing shim logic and full userland maple tree support contained in tools/testing/radix-tree/ and tools/include/linux/, separating out shared components of the radix tree implementation to provide this testing. Kernel functionality is stubbed and shimmed as needed in tools/testing/vma/ which contains a fully functional userland vma_internal.h file and which imports mm/vma.c and mm/vma.h to be directly tested from userland. A simple, skeleton testing implementation is provided in tools/testing/vma/vma.c as a proof-of-concept, asserting that simple VMA merge, modify (testing split), expand and shrink functionality work correctly. v2: * NOMMU fixup in mm/vma.h. * Fixup minor incorrect header edits and remove accidentally included empty test file, and incorrect license header. * Remove generated/autoconf.h file from tools/testing/vma/ and create directory if doesn't already exist. * Have vma binary return an error code if any tests fail. v1: * Fix test_simple_modify() to specify correct prev. * Improve vma test Makefile so it picks up dependency changes correctly. * Rename relocate_vma() to relocate_vma_down(). * Remove shift_arg_pages() and invoked relocate_vma_down() directly from setup_arg_pages(). *
