[PATCH] replace free hugepage folios after migration

by yangge1116＠126.com

From: yangge <yangge1116(a)126.com> My machine has 4 NUMA nodes, each equipped with 32GB of memory. I have configured each NUMA node with 16GB of CMA and 16GB of in-use hugetlb pages. The allocation of contiguous memory via the cma_alloc() function can fail probabilistically. The cma_alloc() function may fail if it sees an in-use hugetlb page within the allocation range, even if that page has already been migrated. When in-use hugetlb pages are migrated, they may simply be released back into the free hugepage pool instead of being returned to the buddy system. This can cause the test_pages_isolated() function check to fail, ultimately leading to the failure of the cma_alloc() function: cma_alloc() __alloc_contig_migrate_range() // migrate in-use hugepage test_pages_isolated() __test_page_isolated_in_pageblock() PageBuddy(page) // check if the page is in buddy To address this issue, we will add a function named replace_free_hugepage_folios(). This function will replace the hugepage in the free hugepage pool with a new one and release the old one to the buddy system. After the migration of in-use hugetlb pages is completed, we will invoke the replace_free_hugepage_folios() function to ensure that these hugepages are properly released to the buddy system. Following this step, when the test_pages_isolated() function is executed for inspection, it will successfully pass.

[PATCH v4 resend] drm/meson: switch to a managed drm device

by Anastasia Belova

Switch to a managed drm device to cleanup some error handling and make future work easier. Fix dereference of NULL in meson_drv_bind_master by removing drm_dev_put(drm) before meson_encoder_*_remove and component_unbind_all where drm is dereferenced.

[BUG] When running btrfs with block size (4K) smaller than page size (64K, aarch64), there is a very high chance to crash the kernel at generic/750, with the following messages: (before the call traces, there are 3 extra debug messages added) BTRFS warning (device dm-3): read-write for sector size 4096 with page size 65536 is experimental BTRFS info (device dm-3): checking UUID tree hrtimer: interrupt took 5451385 ns BTRFS error (device dm-3): cow_file_range failed, root=4957 inode=257 start=1605632 len=69632: -28 BTRFS error (device dm-3): run_delalloc_nocow failed, root=4957 inode=257 start=1605632 len=69632: -28 BTRFS error (device dm-3): failed to run delalloc range, root=4957 ino=257 folio=1572864 submit_bitmap=8-15 start=1605632 len=69632: -28 ------------[ cut here ]------------ WARNING: CPU: 2 PID: 3020984 at ordered-data.c:360 can_finish_ordered_extent+0x370/0x3b8 [btrfs] CPU: 2 UID: 0 PID: 3020984 Comm: kworker/u24:1 Tainted: G OE 6.13.0-rc1-custom+ #89 Tainted: [O]=OOT_MODULE, [E]=UNSIGNED_MODULE Hardware name: QEMU KVM Virtual Machine, BIOS unknown 2/2/2022 Workqueue: events_unbound btrfs_async_reclaim_data_space [btrfs] pc : can_finish_ordered_extent+0x370/0x3b8 [btrfs] lr : can_finish_ordered_extent+0x1ec/0x3b8 [btrfs] Call trace: can_finish_ordered_extent+0x370/0x3b8 [btrfs] (P) can_finish_ordered_extent+0x1ec/0x3b8 [btrfs] (L) btrfs_mark_ordered_io_finished+0x130/0x2b8 [btrfs] extent_writepage+0x10c/0x3b8 [btrfs] extent_write_cache_pages+0x21c/0x4e8 [btrfs] btrfs_writepages+0x94/0x160 [btrfs] do_writepages+0x74/0x190 filemap_fdatawrite_wbc+0x74/0xa0 start_delalloc_inodes+0x17c/0x3b0 [btrfs] btrfs_start_delalloc_roots+0x17c/0x288 [btrfs] shrink_delalloc+0x11c/0x280 [btrfs] flush_space+0x288/0x328 [btrfs] btrfs_async_reclaim_data_space+0x180/0x228 [btrfs] process_one_work+0x228/0x680 worker_thread+0x1bc/0x360 kthread+0x100/0x118 ret_from_fork+0x10/0x20 ---[ end trace 0000000000000000 ]--- BTRFS critical (device dm-3): bad ordered extent accounting, root=4957 ino=257 OE offset=1605632 OE len=16384 to_dec=16384 left=0 BTRFS critical (device dm-3): bad ordered extent accounting, root=4957 ino=257 OE offset=1622016 OE len=12288 to_dec=12288 left=0 Unable to handle kernel NULL pointer dereference at virtual address 0000000000000008 BTRFS critical (device dm-3): bad ordered extent accounting, root=4957 ino=257 OE offset=1634304 OE len=8192 to_dec=4096 left=0 CPU: 1 UID: 0 PID: 3286940 Comm: kworker/u24:3 Tainted: G W OE 6.13.0-rc1-custom+ #89 Hardware name: QEMU KVM Virtual Machine, BIOS unknown 2/2/2022 Workqueue: btrfs_work_helper [btrfs] (btrfs-endio-write) pstate: 404000c5 (nZcv daIF +PAN -UAO -TCO -DIT -SSBS BTYPE=--) pc : process_one_work+0x110/0x680 lr : worker_thread+0x1bc/0x360 Call trace: process_one_work+0x110/0x680 (P) worker_thread+0x1bc/0x360 (L) worker_thread+0x1bc/0x360 kthread+0x100/0x118 ret_from_fork+0x10/0x20 Code: f84086a1 f9000fe1 53041c21 b9003361 (f9400661) ---[ end trace 0000000000000000 ]--- Kernel panic - not syncing: Oops: Fatal exception SMP: stopping secondary CPUs SMP: failed to stop secondary CPUs 2-3 Dumping ftrace buffer: (ftrace buffer empty) Kernel Offset: 0x275bb9540000 from 0xffff800080000000 PHYS_OFFSET: 0xffff8fbba0000000 CPU features: 0x100,00000070,00801250,8201720b [CAUSE] The above warning is triggered immediately after the delalloc range failure, this happens in the following sequence: - Range [1568K, 1636K) is dirty 1536K 1568K 1600K 1636K 1664K | |/////////|////////| | Where 1536K, 1600K and 1664K are page boundaries (64K page size) - Enter extent_writepage() for page 1536K - Enter run_delalloc_nocow() with locked page 1536K and range [1568K, 1636K) This is due to the inode has preallocated extents. - Enter cow_file_range() with locked page 1536K and range [1568K, 1636K) - btrfs_reserve_extent() only reserved two extents The main loop of cow_file_range() only reserved two data extents, Now we have: 1536K 1568K 1600K 1636K 1664K | |<-->|<--->|/|///////| | 1584K 1596K Range [1568K, 1596K) has ordered extent reserved. - btrfs_reserve_extent() failed inside cow_file_range() for file offset 1596K This is already a bug in our space reservation code, but for now let's focus on the error handling path. Now cow_file_range() returned -ENOSPC. - btrfs_run_delalloc_range() do error cleanup <<< ROOT CAUSE Call btrfs_cleanup_ordered_extents() with locked folio 1536K and range [1568K, 1636K) Function btrfs_cleanup_ordered_extents() normally needs to skip the ranges inside the folio, as it will normally be cleaned up by extent_writepage(). Such split error handling is already problematic in the first place. What's worse is the folio range skipping itself, which is not taking subpage cases into consideration at all, it will only skip the range if the page start >= the range start. In our case, the page start < the range start, since for subpage cases we can have delalloc ranges inside the folio but not covering the folio. So it doesn't skip the page range at all. This means all the ordered extents, both [1568K, 1584K) and [1584K, 1596K) will be marked as IOERR. And those two ordered extents have no more pending ios, it is marked finished, and *QUEUED* to be deleted from the io tree. - extent_writepage() do error cleanup Call btrfs_mark_ordered_io_finished() for the range [1536K, 1600K). Although ranges [1568K, 1584K) and [1584K, 1596K) are finished, the deletion from io tree is async, it may or may not happen at this timing. If the ranges are not yet removed, we will do double cleaning on those ranges, triggers the above ordered extent warnings. In theory there are other bugs, like the cleanup in extent_writepage() can cause double accounting on ranges that are submitted async (compression for example). But that's much harder to trigger because normally we do not mix regular and compression delalloc ranges. [FIX] The folio range split is already buggy and not subpage compatible, it's introduced a long time ago where subpage support is not even considered. So instead of splitting the ordered extents cleanup into the folio range and out of folio range, do all the cleanup inside writepage_delalloc(). - Pass @NULL as locked_folio for btrfs_cleanup_ordered_extents() in btrfs_run_delalloc_range() - Skip the btrfs_cleanup_ordered_extents() if writepage_delalloc() failed So all ordered extents are only cleaned up by btrfs_run_delalloc_range(). - Handle the ranges that already have ordered extents allocated If part of the folio already has ordered extent allocated, and btrfs_run_delalloc_range() failed, we also need to cleanup that range. Now we have a concentrated error handling for ordered extents during btrfs_run_delalloc_range().

[PATCH] clk: clk-loongson2: Fix the number count of clk provider

by Binbin Zhou

Since commit 02fb4f008433 ("clk: clk-loongson2: Fix potential buffer overflow in flexible-array member access"), the clk provider register is failed. The count of `clks_num` is shown below: for (p = data; p->name; p++) clks_num++; In fact, `clks_num` represents the number of SoC clocks and should be expressed as the maximum value of the clock binding id in use (p->id + 1). Now we fix it to avoid the following error when trying to register a clk provider: [ 13.409595] of_clk_hw_onecell_get: invalid index 17 Fixes: 02fb4f008433 ("clk: clk-loongson2: Fix potential buffer overflow in flexible-array member access") Cc: stable(a)vger.kernel.org Signed-off-by: Binbin Zhou <zhoubinbin(a)loongson.cn> --- drivers/clk/clk-loongson2.c | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) diff --git a/drivers/clk/clk-loongson2.c b/drivers/clk/clk-loongson2.c index 6bf51d5a49a1..b1b2038acd0b 100644 --- a/drivers/clk/clk-loongson2.c +++ b/drivers/clk/clk-loongson2.c @@ -294,7 +294,7 @@ static int loongson2_clk_probe(struct platform_device *pdev) return -EINVAL; for (p = data; p->name; p++) - clks_num++; + clks_num = max(clks_num, p->id + 1); clp = devm_kzalloc(dev, struct_size(clp, clk_data.hws, clks_num), GFP_KERNEL); -- 2.43.5

[PATCH v3] arm64/sme: Move storage of reg_smidr to __cpuinfo_store_cpu()

by Mark Brown

In commit 892f7237b3ff ("arm64: Delay initialisation of cpuinfo_arm64::reg_{zcr,smcr}") we moved access to ZCR, SMCR and SMIDR later in the boot process in order to ensure that we don't attempt to interact with them if SVE or SME is disabled on the command line. Unfortunately when initialising the boot CPU in init_cpu_features() we work on a copy of the struct cpuinfo_arm64 for the boot CPU used only during boot, not the percpu copy used by the sysfs code. The expectation of the feature identification code was that the ID registers would be read in __cpuinfo_store_cpu() and the values not modified by init_cpu_features(). The main reason for the original change was to avoid early accesses to ZCR on practical systems that were seen shipping with SVE reported in ID registers but traps enabled at EL3 and handled as fatal errors, SME was rolled in due to the similarity with SVE. Since then we have removed the early accesses to ZCR and SMCR in commits: abef0695f9665c3d ("arm64/sve: Remove ZCR pseudo register from cpufeature code") 391208485c3ad50f ("arm64/sve: Remove SMCR pseudo register from cpufeature code") so only the SMIDR_EL1 part of the change remains. Since SMIDR_EL1 is only trapped via FEAT_IDST and not the SME trap it is less likely to be affected by similar issues, and the factors that lead to issues with SVE are less likely to apply to SME. Since we have not yet seen practical SME systems that need to use a command line override (and are only just beginning to see SME systems at all) and the ID register read is much more likely to be safe let's just store SMIDR_EL1 along with all the other ID register reads in __cpuinfo_store_cpu(). This issue wasn't apparent when testing on emulated platforms that do not report values in SMIDR_EL1.

[PATCH v9 0/4] clk: qcom: Add support for multiple power-domains for a clock controller.

by Bryan O'Donoghue

Changes in v9: - Added patch to unwind pm subdomains in reverse order. It would also be possible to squash this patch into patch#2 but, my own preference is for more granular patches like this instead of "slipping in" functional changes in larger patches like #2. - bod - Unwinding pm subdomain on error in patch #2. To facilitate this change patch #1 was created - Vlad - Drops Bjorn's RB on patch #2. There is a small churn in this patch but enough that a reviewer might reasonably expect RB to be given again. - Amends commit log for patch #3 further. v8 added a lot to the commit log to provide further information but, it is clear from the comments I received on the commit log that the added verbiage was occlusive not elucidative. Reduce down the commit log of patch #3 - especially Q&A item #1. Sometimes less is more. - Link to v8: https://lore.kernel.org/r/20241211-b4-linux-next-24-11-18-clock-multiple-po… Changes in v8: - Picks up change I agreed with Vlad but failed to cherry-pick into my b4 tree - Vlad/Bod - Rewords the commit log for patch #3. As I read it I decided I might translate bits of it from thought-stream into English - Bod - Link to v7: https://lore.kernel.org/r/20241211-b4-linux-next-24-11-18-clock-multiple-po… Changes in v7: - Expand commit log in patch #3 I've discussed with Bjorn on IRC and video what to put into the log here and captured most of what we discussed. Mostly the point here is voting for voltages in the power-domain list is up to the drivers to do with performance states/opp-tables not for the GDSC code. - Bjorn/Bryan - Link to v6: https://lore.kernel.org/r/20241129-b4-linux-next-24-11-18-clock-multiple-po… Changes in v6: - Passes NULL to second parameter of devm_pm_domain_attach_list - Vlad - Link to v5: https://lore.kernel.org/r/20241128-b4-linux-next-24-11-18-clock-multiple-po… Changes in v5: - In-lines devm_pm_domain_attach_list() in probe() directly - Vlad - Link to v4: https://lore.kernel.org/r/20241127-b4-linux-next-24-11-18-clock-multiple-po… v4: - Adds Bjorn's RB to first patch - Bjorn - Drops the 'd' in "and int" - Bjorn - Amends commit log of patch 3 to capture a number of open questions - Bjorn - Link to v3: https://lore.kernel.org/r/20241126-b4-linux-next-24-11-18-clock-multiple-po… v3: - Fixes commit log "per which" - Bryan - Link to v2: https://lore.kernel.org/r/20241125-b4-linux-next-24-11-18-clock-multiple-po… v2: The main change in this version is Bjorn's pointing out that pm_runtime_* inside of the gdsc_enable/gdsc_disable path would be recursive and cause a lockdep splat. Dmitry alluded to this too. Bjorn pointed to stuff being done lower in the gdsc_register() routine that might be a starting point. I iterated around that idea and came up with patch #3. When a gdsc has no parent and the pd_list is non-NULL then attach that orphan GDSC to the clock controller power-domain list. Existing subdomain code in gdsc_register() will connect the parent GDSCs in the clock-controller to the clock-controller subdomain, the new code here does that same job for a list of power-domains the clock controller depends on. To Dmitry's point about MMCX and MCX dependencies for the registers inside of the clock controller, I have switched off all references in a test dtsi and confirmed that accessing the clock-controller regs themselves isn't required. On the second point I also verified my test branch with lockdep on which was a concern with the pm_domain version of this solution but I wanted to cover it anyway with the new approach for completeness sake. Here's the item-by-item list of changes: - Adds a patch to capture pm_genpd_add_subdomain() result code - Bryan - Changes changelog of second patch to remove singleton and generally to make the commit log easier to understand - Bjorn - Uses demv_pm_domain_attach_list - Vlad - Changes error check to if (ret < 0 && ret != -EEXIST) - Vlad - Retains passing &pd_data instead of NULL - because NULL doesn't do the same thing - Bryan/Vlad - Retains standalone function qcom_cc_pds_attach() because the pd_data enumeration looks neater in a standalone function - Bryan/Vlad - Drops pm_runtime in favour of gdsc_add_subdomain_list() for each power-domain in the pd_list. The pd_list will be whatever is pointed to by power-domains = <> in the dtsi - Bjorn - Link to v1: https://lore.kernel.org/r/20241118-b4-linux-next-24-11-18-clock-multiple-po… v1: On x1e80100 and it's SKUs the Camera Clock Controller - CAMCC has multiple power-domains which power it. Usually with a single power-domain the core platform code will automatically switch on the singleton power-domain for you. If you have multiple power-domains for a device, in this case the clock controller, you need to switch those power-domains on/off yourself. The clock controllers can also contain Global Distributed Switch Controllers - GDSCs which themselves can be referenced from dtsi nodes ultimately triggering a gdsc_en() in drivers/clk/qcom/gdsc.c. As an example: cci0: cci@ac4a000 { power-domains = <&camcc TITAN_TOP_GDSC>; }; This series adds the support to attach a power-domain list to the clock-controllers and the GDSCs those controllers provide so that in the case of the above example gdsc_toggle_logic() will trigger the power-domain list with pm_runtime_resume_and_get() and pm_runtime_put_sync() respectively.
