Carlos reports an earlier patch, c0cd6f557b90 ("mm: page_alloc: fix freelist movement during block conversion"), as the root cause for a regression in worst-case zone->lock+irqoff hold times. Both of these patches modify the page allocator's fallback path to be less greedy in an effort to stave off fragmentation. The flip side of this is that fallbacks are also less productive each time around, which means the fallback search can run much more frequently. Carlos' traces point to rmqueue_bulk() specifically, which tries to refill the percpu cache by allocating a large batch of pages in a loop. It highlights how once the native freelists are exhausted, the fallback code first scans orders top-down for whole blocks to claim, then falls back to a bottom-up search for the smallest buddy to steal. For the next batch page, it goes through the same thing again. This can be made more efficient. Since rmqueue_bulk() holds the zone->lock over the entire batch, the freelists are not subject to outside changes; when the search for a block to claim has already failed, there is no point in trying again for the next page. Modify __rmqueue() to remember the last successful fallback mode, and restart directly from there on the next rmqueue_bulk() iteration. Oliver confirms that this improves beyond the regression that the test robot reported against c2f6ea38fc1b: commit: f3b92176f4 ("tools/selftests: add guard region test for /proc/$pid/pagemap") c2f6ea38fc ("mm: page_alloc: don't steal single pages from biggest buddy") acc4d5ff0b ("Merge tag 'net-6.15-rc0' of git://git.kernel.org/pub/scm/linux/kernel/git/netdev/net") 2c847f27c3 ("mm: page_alloc: speed up fallbacks in rmqueue_bulk()") <--- your patch f3b92176f4f7100f c2f6ea38fc1b640aa7a2e155cc1 acc4d5ff0b61eb1715c498b6536 2c847f27c37da65a93d23c237c5 ---------------- --------------------------- --------------------------- --------------------------- %stddev %change %stddev %change %stddev %change %stddev \ | \ | \ | \ 25525364 ± 3% -56.4% 11135467 -57.8% 10779336 +31.6% 33581409 vm-scalability.throughput Carlos confirms that worst-case times are almost fully recovered compared to before the earlier culprit patch: 2dd482ba627d (before freelist hygiene): 1ms c0cd6f557b90 (after freelist hygiene): 90ms next-20250319 (steal smallest buddy): 280ms this patch : 8ms [jackmanb(a)google.com: comment updates] Link: https://lkml.kernel.org/r/D92AC0P9594X.3BML64MUKTF8Z@google.com [hannes(a)cmpxchg.org: reset rmqueue_mode in rmqueue_buddy() error loop, per Yunsheng Lin] Link: https://lkml.kernel.org/r/20250409140023.GA2313@cmpxchg.org Link: https://lkml.kernel.org/r/20250407180154.63348-1-hannes@cmpxchg.org Fixes: c0cd6f557b90 ("mm: page_alloc: fix freelist movement during block conversion") Fixes: c2f6ea38fc1b ("mm: page_alloc: don't steal single pages from biggest buddy") Signed-off-by: Johannes Weiner <hannes(a)cmpxchg.org> Signed-off-by: Brendan Jackman <jackmanb(a)google.com> Reported-by: kernel test robot <oliver.sang(a)intel.com> Reported-by: Carlos Song <carlos.song(a)nxp.com> Tested-by: Carlos Song <carlos.song(a)nxp.com> Tested-by: kernel test robot <oliver.sang(a)intel.com> Closes: https://lore.kernel.org/oe-lkp/202503271547.fc08b188-lkp@intel.com Reviewed-by: Brendan Jackman <jackmanb(a)google.com> Tested-by: Shivank Garg <shivankg(a)amd.com> Acked-by: Zi Yan <ziy(a)nvidia.com> Reviewed-by: Vlastimil Babka <vbabka(a)suse.cz> Cc: <stable(a)vger.kernel.org> [6.10+] Signed-off-by: Andrew Morton <akpm(a)linux-foundation.org> diff --git a/mm/page_alloc.c b/mm/page_alloc.c index 9a219fe8e130..1715e34b91af 100644 --- a/mm/page_alloc.c +++ b/mm/page_alloc.c @@ -2183,23 +2183,15 @@ try_to_claim_block(struct zone *zone, struct page *page, } /* - * Try finding a free buddy page on the fallback list. - * - * This will attempt to claim a whole pageblock for the requested type - * to ensure grouping of such requests in the future. - * - * If a whole block cannot be claimed, steal an individual page, regressing to - * __rmqueue_smallest() logic to at least break up as little contiguity as - * possible. + * Try to allocate from some fallback migratetype by claiming the entire block, + * i.e. converting it to the allocation's start migratetype. * * The use of signed ints for order and current_order is a deliberate * deviation from the rest of this file, to make the for loop * condition simpler. - * - * Return the stolen page, or NULL if none can be found. */ static __always_inline struct page * -__rmqueue_fallback(struct zone *zone, int order, int start_migratetype, +__rmqueue_claim(struct zone *zone, int order, int start_migratetype, unsigned int alloc_flags) { struct free_area *area; @@ -2237,14 +2229,29 @@ __rmqueue_fallback(struct zone *zone, int order, int start_migratetype, page = try_to_claim_block(zone, page, current_order, order, start_migratetype, fallback_mt, alloc_flags); - if (page) - goto got_one; + if (page) { + trace_mm_page_alloc_extfrag(page, order, current_order, + start_migratetype, fallback_mt); + return page; + } } - if (alloc_flags & ALLOC_NOFRAGMENT) - return NULL; + return NULL; +} + +/* + * Try to steal a single page from some fallback migratetype.

[PATCH v2 0/7] accel/ivpu: Add context violation handling for 6.12

by Jacek Lawrynowicz

These patchset adds support for VPU_JSM_STATUS_MVNCI_CONTEXT_VIOLATION_HW message added in recent VPU firmware. Without it the driver will not be able to process any jobs after this message is received and would need to be reloaded. Most patches are as-is from upstream besides these two: - Fix locking order in ivpu_job_submit - Abort all jobs after command queue unregister Both these patches need to be rebased because of missing new CMDQ UAPI changes that should not be backported to stable. Changes since v1: - Documented deviations from the original upstream patches in commit messages Andrew Kreimer (1): accel/ivpu: Fix a typo Andrzej Kacprowski (1): accel/ivpu: Update VPU FW API headers Karol Wachowski (4): accel/ivpu: Use xa_alloc_cyclic() instead of custom function accel/ivpu: Abort all jobs after command queue unregister accel/ivpu: Fix locking order in ivpu_job_submit accel/ivpu: Add handling of VPU_JSM_STATUS_MVNCI_CONTEXT_VIOLATION_HW Tomasz Rusinowicz (1): accel/ivpu: Make DB_ID and JOB_ID allocations incremental drivers/accel/ivpu/ivpu_drv.c | 38 ++-- drivers/accel/ivpu/ivpu_drv.h | 9 + drivers/accel/ivpu/ivpu_job.c | 125 +++++++++--- drivers/accel/ivpu/ivpu_job.h | 1 + drivers/accel/ivpu/ivpu_jsm_msg.c | 3 +- drivers/accel/ivpu/ivpu_mmu.c | 3 +- drivers/accel/ivpu/ivpu_sysfs.c | 5 +- drivers/accel/ivpu/vpu_boot_api.h | 45 +++-- drivers/accel/ivpu/vpu_jsm_api.h | 303 +++++++++++++++++++++++++----- 9 files changed, 412 insertions(+), 120 deletions(-) -- 2.45.1

[PATCH v6.1] md: move initialization and destruction of 'io_acct_set' to md.c

by Yu Kuai

From: Yu Kuai <yukuai3(a)huawei.com> commit c567c86b90d4715081adfe5eb812141a5b6b4883 upstream. 'io_acct_set' is only used for raid0 and raid456, prepare to use it for raid1 and raid10, so that io accounting from different levels can be consistent. By the way, follow up patches will also use this io clone mechanism to make sure 'active_io' represents in flight io, not io that is dispatching, so that mddev_suspend will wait for io to be done as designed.

That meant that, when a buffer containing vertex data was written to, it was necessary to issue a PIPE_CONTROL::VF Cache Invalidate to invalidate any VF L2 cachelines associated with that buffer, so the new value would be properly read from memory. Since Tigerlake and later, VERTEX_BUFFER_STATE and 3DSTATE_INDEX_BUFFER have included an "L3 Bypass Enable" bit which userspace drivers can set to request that the vertex fetcher unit snoop L3. However, unlike most true L3 clients, the "VF Cache Invalidate" bit continues to only invalidate the VF L2 cache - and not any associated L3 lines. To handle that, PIPE_CONTROL has a new "L3 Read Only Cache Invalidation Bit", which according to the docs, "controls the invalidation of the Geometry streams cached in L3 cache at the top of the pipe." In other words, the vertex and index buffer data that gets cached in L3 when "L3 Bypass Disable" is set. Mesa always sets L3 Bypass Disable so that the VF unit snoops L3, and whenever it issues a VF Cache Invalidate, it also issues a L3 Read Only Cache Invalidate so that both L2 and L3 vertex data is invalidated. xe is issuing VF cache invalidates too (which handles cases like CPU writes to a buffer between GPU batches). Because userspace may enable L3 snooping, it needs to issue an L3 Read Only Cache Invalidate as well. Fixes significant flickering in Firefox on Meteorlake, which was writing to vertex buffers via the CPU between batches; the missing L3 Read Only invalidates were causing the vertex fetcher to read stale data from L3.

[PATCH 6.6 0/2] PCI: imx6: Fix i.MX7D controller_id backport regression

by Ryan Matthews

Hello, This fixes an i.Mx 7D SoC PCIe regression caused by a backport mistake. The regression is broken PCIe initialization and for me a boot hang. I don't know how to organize this. I think a revert and redo best captures what's happening. To complicate things, it looks like the redo patch could also be applied to 5.4, 5.10, 5.15, and 6.1. But those versions don't have the original backport commit. Version 6.12 matches master and needs no change. One conflict resolution is needed to apply the redo patch back to versions 6.1 -> 5.15 -> 5.10. One more resolution to apply back to -> 5.4. Patches against those other versions aren't included here. -- Ryan Richard Zhu (1): PCI: imx6: Skip controller_id generation logic for i.MX7D Ryan Matthews (1): Revert "PCI: imx6: Skip controller_id generation logic for i.MX7D" drivers/pci/controller/dwc/pci-imx6.c | 3 ++- 1 file changed, 2 insertions(+), 1 deletion(-) base-commit: 814637ca257f4faf57a73fd4e38888cce88b5911 -- 2.47.2

Carlos reports an earlier patch, c0cd6f557b90 ("mm: page_alloc: fix freelist movement during block conversion"), as the root cause for a regression in worst-case zone->lock+irqoff hold times. Both of these patches modify the page allocator's fallback path to be less greedy in an effort to stave off fragmentation. The flip side of this is that fallbacks are also less productive each time around, which means the fallback search can run much more frequently. Carlos' traces point to rmqueue_bulk() specifically, which tries to refill the percpu cache by allocating a large batch of pages in a loop. It highlights how once the native freelists are exhausted, the fallback code first scans orders top-down for whole blocks to claim, then falls back to a bottom-up search for the smallest buddy to steal. For the next batch page, it goes through the same thing again. This can be made more efficient. Since rmqueue_bulk() holds the zone->lock over the entire batch, the freelists are not subject to outside changes; when the search for a block to claim has already failed, there is no point in trying again for the next page. Modify __rmqueue() to remember the last successful fallback mode, and restart directly from there on the next rmqueue_bulk() iteration. Oliver confirms that this improves beyond the regression that the test robot reported against c2f6ea38fc1b: commit: f3b92176f4 ("tools/selftests: add guard region test for /proc/$pid/pagemap") c2f6ea38fc ("mm: page_alloc: don't steal single pages from biggest buddy") acc4d5ff0b ("Merge tag 'net-6.15-rc0' of git://git.kernel.org/pub/scm/linux/kernel/git/netdev/net") 2c847f27c3 ("mm: page_alloc: speed up fallbacks in rmqueue_bulk()") <--- your patch f3b92176f4f7100f c2f6ea38fc1b640aa7a2e155cc1 acc4d5ff0b61eb1715c498b6536 2c847f27c37da65a93d23c237c5 ---------------- --------------------------- --------------------------- --------------------------- %stddev %change %stddev %change %stddev %change %stddev \ | \ | \ | \ 25525364 ± 3% -56.4% 11135467 -57.8% 10779336 +31.6% 33581409 vm-scalability.throughput Carlos confirms that worst-case times are almost fully recovered compared to before the earlier culprit patch: 2dd482ba627d (before freelist hygiene): 1ms c0cd6f557b90 (after freelist hygiene): 90ms next-20250319 (steal smallest buddy): 280ms this patch : 8ms [jackmanb(a)google.com: comment updates] Link: https://lkml.kernel.org/r/D92AC0P9594X.3BML64MUKTF8Z@google.com [hannes(a)cmpxchg.org: reset rmqueue_mode in rmqueue_buddy() error loop, per Yunsheng Lin] Link: https://lkml.kernel.org/r/20250409140023.GA2313@cmpxchg.org Link: https://lkml.kernel.org/r/20250407180154.63348-1-hannes@cmpxchg.org Fixes: c0cd6f557b90 ("mm: page_alloc: fix freelist movement during block conversion") Fixes: c2f6ea38fc1b ("mm: page_alloc: don't steal single pages from biggest buddy") Signed-off-by: Johannes Weiner <hannes(a)cmpxchg.org> Signed-off-by: Brendan Jackman <jackmanb(a)google.com> Reported-by: kernel test robot <oliver.sang(a)intel.com> Reported-by: Carlos Song <carlos.song(a)nxp.com> Tested-by: Carlos Song <carlos.song(a)nxp.com> Tested-by: kernel test robot <oliver.sang(a)intel.com> Closes: https://lore.kernel.org/oe-lkp/202503271547.fc08b188-lkp@intel.com Reviewed-by: Brendan Jackman <jackmanb(a)google.com> Tested-by: Shivank Garg <shivankg(a)amd.com> Acked-by: Zi Yan <ziy(a)nvidia.com> Reviewed-by: Vlastimil Babka <vbabka(a)suse.cz> Cc: <stable(a)vger.kernel.org> [6.10+] Signed-off-by: Andrew Morton <akpm(a)linux-foundation.org> diff --git a/mm/page_alloc.c b/mm/page_alloc.c index 9a219fe8e130..1715e34b91af 100644 --- a/mm/page_alloc.c +++ b/mm/page_alloc.c @@ -2183,23 +2183,15 @@ try_to_claim_block(struct zone *zone, struct page *page, } /* - * Try finding a free buddy page on the fallback list. - * - * This will attempt to claim a whole pageblock for the requested type - * to ensure grouping of such requests in the future. - * - * If a whole block cannot be claimed, steal an individual page, regressing to - * __rmqueue_smallest() logic to at least break up as little contiguity as - * possible. + * Try to allocate from some fallback migratetype by claiming the entire block, + * i.e. converting it to the allocation's start migratetype. * * The use of signed ints for order and current_order is a deliberate * deviation from the rest of this file, to make the for loop * condition simpler. - * - * Return the stolen page, or NULL if none can be found. */ static __always_inline struct page * -__rmqueue_fallback(struct zone *zone, int order, int start_migratetype, +__rmqueue_claim(struct zone *zone, int order, int start_migratetype, unsigned int alloc_flags) { struct free_area *area; @@ -2237,14 +2229,29 @@ __rmqueue_fallback(struct zone *zone, int order, int start_migratetype, page = try_to_claim_block(zone, page, current_order, order, start_migratetype, fallback_mt, alloc_flags); - if (page) - goto got_one; + if (page) { + trace_mm_page_alloc_extfrag(page, order, current_order, + start_migratetype, fallback_mt); + return page; + } } - if (alloc_flags & ALLOC_NOFRAGMENT) - return NULL; + return NULL; +} + +/* + * Try to steal a single page from some fallback migratetype.

[PATCH v3 1/3] media: videobuf2: use sgtable-based scatterlist wrappers

by Marek Szyprowski

Use common wrappers operating directly on the struct sg_table objects to fix incorrect use of scatterlists sync calls. dma_sync_sg_for_*() functions have to be called with the number of elements originally passed to dma_map_sg_*() function, not the one returned in sgt->nents.

[PATCH] spi: tegra114: Use value to check for invalid delays

by Aaron Kling via B4 Relay

[PATCH] drm/dp: Fix Write_Status_Update_Request AUX request format

by Wayne Lin

[Why] Notice AUX request format of I2C-over-AUX with Write_Status_Update_Request flag set is incorrect. It should be address only request without length and data like: "SYNC->COM3:0 (= 0110)|0000-> 0000|0000-> 0|7-bit I2C address (the same as the last)-> STOP->". [How] Refer to DP v2.1 Table 2-178, correct the Write_Status_Update_Request to be address only request. Note that we might receive 0 returned by aux->transfer() when receive reply I2C_ACK|AUX_ACK of Write_Status_Update_Request transaction. Which indicating all data bytes get written. We should avoid to return 0 bytes get transferred under this case.

[PATCH v4 00/25] Add support for HEVC and VP9 codecs in decoder

by Dikshita Agarwal

Hi All, This patch series adds initial support for the HEVC(H.265) and VP9 codecs in iris decoder. The objective of this work is to extend the decoder's capabilities to handle HEVC and VP9 codec streams, including necessary format handling and buffer management. In addition, the series also includes a set of fixes to address issues identified during testing of these additional codecs. These patches also address the comments and feedback received from the RFC patches previously sent. I have made the necessary improvements based on the community's suggestions. Changes in v4: - Splitted patch patch 06/23 in two patches (Bryan) - Simplified the conditional logic in patch 13/23 (Bryan) - Improved commit description for patch patch 13/23 (Nicolas) - Fix the value of H265_NUM_TILE_ROW macro (Neil) - Link to v3: https://lore.kernel.org/r/20250502-qcom-iris-hevc-vp9-v3-0-552158a10a7d@qui… Changes in v3: - Introduced two wrappers with explicit names to handle destroy internal buffers (Nicolas) - Used sub state check instead of introducing new boolean (Vikash) - Addressed other comments (Vikash) - Reorderd patches to have all fixes patches first (Dmitry) - Link to v2: https://lore.kernel.org/r/20250428-qcom-iris-hevc-vp9-v2-0-3a6013ecb8a5@qui… Changes in v2: - Added Changes to make sure all buffers are released in session close (bryna) - Added tracking for flush responses to fix a timing issue. - Added a handling to fix timing issue in reconfig - Splitted patch 06/20 in two patches (Bryan) - Added missing fixes tag (bryan) - Updated fluster report (Nicolas) - Link to v1: https://lore.kernel.org/r/20250408-iris-dec-hevc-vp9-v1-0-acd258778bd6@quic… Changes sinces RFC: - Added additional fixes to address issues identified during further testing. - Moved typo fix to a seperate patch [Neil] - Reordered the patches for better logical flow and clarity [Neil, Dmitry] - Added fixes tag wherever applicable [Neil, Dmitry] - Removed the default case in the switch statement for codecs [Bryan] - Replaced if-else statements with switch-case [Bryan] - Added comments for mbpf [Bryan] - RFC: https://lore.kernel.org/linux-media/20250305104335.3629945-1-quic_dikshita@… This patch series depends on [1] & [2] [1] https://lore.kernel.org/linux-media/20250417-topic-sm8x50-iris-v10-v7-0-f02… [2] https://lore.kernel.org/linux-media/20250424-qcs8300_iris-v5-0-f118f505c300… These patches are tested on SM8250 and SM8550 with v4l2-ctl and Gstreamer for HEVC and VP9 decoders, at the same time ensured that the existing H264 decoder functionality remains uneffected. Note: 1 of the fluster compliance test is fixed with firmware [3] [3]: https://lore.kernel.org/linux-firmware/1a511921-446d-cdc4-0203-084c88a5dc1e… The result of fluster test on SM8550: 131/147 testcases passed while testing JCT-VC-HEVC_V1 with GStreamer-H.265-V4L2-Gst1.0.

[PATCH v1] ufs: core: fix hwq_id type and value

by peter.wang＠mediatek.com

From: Peter Wang <peter.wang(a)mediatek.com> Because the member id of struct ufs_hw_queue is u32 (hwq->id) and the trace entry hwq_id is also u32, the type should be changed to u32. If mcq is not supported, SDB mode only supports one hardware queue, for which setting the hwq_id to 0 is more suitable.

[merged mm-hotfixes-stable] mm-fix-folio_pte_batch-on-xen-pv.patch removed from -mm tree

by Andrew Morton

The quilt patch titled Subject: mm: fix folio_pte_batch() on XEN PV has been removed from the -mm tree. Its filename was mm-fix-folio_pte_batch-on-xen-pv.patch This patch was dropped because it was merged into the mm-hotfixes-stable branch of git://git.kernel.org/pub/scm/linux/kernel/git/akpm/mm ------------------------------------------------------ From: Petr Van��k <arkamar(a)atlas.cz> Subject: mm: fix folio_pte_batch() on XEN PV Date: Fri, 2 May 2025 23:50:19 +0200 On XEN PV, folio_pte_batch() can incorrectly batch beyond the end of a folio due to a corner case in pte_advance_pfn(). Specifically, when the PFN following the folio maps to an invalidated MFN, expected_pte = pte_advance_pfn(expected_pte, nr); produces a pte_none(). If the actual next PTE in memory is also pte_none(), the pte_same() succeeds, if (!pte_same(pte, expected_pte)) break; the loop is not broken, and batching continues into unrelated memory. For example, with a 4-page folio, the PTE layout might look like this: [ 53.465673] [ T2552] folio_pte_batch: printing PTE values at addr=0x7f1ac9dc5000 [ 53.465674] [ T2552] PTE[453] = 000000010085c125 [ 53.465679] [ T2552] PTE[454] = 000000010085d125 [ 53.465682] [ T2552] PTE[455] = 000000010085e125 [ 53.465684] [ T2552] PTE[456] = 000000010085f125 [ 53.465686] [ T2552] PTE[457] = 0000000000000000 <-- not present [ 53.465689] [ T2552] PTE[458] = 0000000101da7125 pte_advance_pfn(PTE[456]) returns a pte_none() due to invalid PFN->MFN mapping. The next actual PTE (PTE[457]) is also pte_none(), so the loop continues and includes PTE[457] in the batch, resulting in 5 batched entries for a 4-page folio. This triggers the following warning: [ 53.465751] [ T2552] page: refcount:85 mapcount:20 mapping:ffff88813ff4f6a8 index:0x110 pfn:0x10085c [ 53.465754] [ T2552] head: order:2 mapcount:80 entire_mapcount:0 nr_pages_mapped:4 pincount:0 [ 53.465756] [ T2552] memcg:ffff888003573000 [ 53.465758] [ T2552] aops:0xffffffff8226fd20 ino:82467c dentry name(?):"libc.so.6" [ 53.465761] [ T2552] flags: 0x2000000000416c(referenced|uptodate|lru|active|private|head|node=0|zone=2) [ 53.465764] [ T2552] raw: 002000000000416c ffffea0004021f08 ffffea0004021908 ffff88813ff4f6a8 [ 53.465767] [ T2552] raw: 0000000000000110 ffff888133d8bd40 0000005500000013 ffff888003573000 [ 53.465768] [ T2552] head: 002000000000416c ffffea0004021f08 ffffea0004021908 ffff88813ff4f6a8 [ 53.465770] [ T2552] head: 0000000000000110 ffff888133d8bd40 0000005500000013 ffff888003573000 [ 53.465772] [ T2552] head: 0020000000000202 ffffea0004021701 000000040000004f 00000000ffffffff [ 53.465774] [ T2552] head: 0000000300000003 8000000300000002 0000000000000013 0000000000000004 [ 53.465775] [ T2552] page dumped because: VM_WARN_ON_FOLIO((_Generic((page + nr_pages - 1), const struct page *: (const struct folio *)_compound_head(page + nr_pages - 1), struct page *: (struct folio *)_compound_head(page + nr_pages - 1))) != folio) Original code works as expected everywhere, except on XEN PV, where pte_advance_pfn() can yield a pte_none() after balloon inflation due to MFNs invalidation. In XEN, pte_advance_pfn() ends up calling __pte()->xen_make_pte()->pte_pfn_to_mfn(), which returns pte_none() when mfn == INVALID_P2M_ENTRY. The pte_pfn_to_mfn() documents that nastiness: If there's no mfn for the pfn, then just create an empty non-present pte. Unfortunately this loses information about the original pfn, so pte_mfn_to_pfn is asymmetric. While such hacks should certainly be removed, we can do better in folio_pte_batch() and simply check ahead of time how many PTEs we can possibly batch in our folio. This way, we can not only fix the issue but cleanup the code: removing the pte_pfn() check inside the loop body and avoiding end_ptr comparison + arithmetic.
