2025-02-10arm64: dts: rockchip: switch Rock 5C to PMIC-based TSHUT resetAlexey Charkov
Radxa Rock 5C supports both CRU-based (default) and PMIC-based reset upon thermal runaway conditions. The former resets the SoC by internally poking the CRU from TSADC, while the latter power-cycles the whole board by pulling the PMIC reset line low in case of uncontrolled overheating. Switch to a PMIC-based reset, as the more 'thorough' of the two. Tested by temporarily setting rockchip,hw-tshut-temp to 65C to simulate overheating - this causes the board to reset when any of the on-chip temperature sensors surpasses the tshut temperature.

2025-02-03arm64: dts: rockchip: Use "dma-noncoherent" in base RK3588 SoC dtsiDragan Simic
The preferred way to denote hardware with non-coherent DMA is to use the "dma-noncoherent" DT property, at both the GIC redistributor and the GIC ITS levels, [1] instead of relying on the compatibles to handle hardware errata, in this case the Rockchip 3588001 errata.

2025-02-03arm64: dts: rockchip: Describe why is HWRNG disabled in RK356x base dtsiDragan Simic
Despite the presence of the hardware random number generator (HWRNG) in the different Rockchip RK356x SoC variants, it remains disabled for the RK3566 SoC because testing showed [1] that it produces unacceptably low quality of random data, for some yet unknown reason. The HWRNG is enabled for the RK3568 SoC, on which the testing showed good quality of the generated random data. To avoid possible confusion in the future, [2] let's have this described briefly in the RK356x base SoC dtsi.

2025-02-03arm64: dts: rockchip: Add finer-grained PWM states for the fan on Rock 5CAlexey Charkov
Radxa Heatsink 6540B, which is the official cooling accessory for the Rock 5C board, includes a small 5V fan, which in my testing spins up reliably at a PWM setting of 24 (out of 255). It is also quite loud at the current minimum setting of 64, and noticeably less so at 24. Introduce two intermediate PWM states at the lower end of the fan's operating range to enable better balance between noise and cooling. Note further that, in my testing, having the fan run at 44 is enough to keep the system from thermal throttling with sustained 100% load on its 8 CPU cores (in 22C ambient temperature and no case) Signed-off-by: Alexey Charkov <alchark@gmail.com> Acked-by: Dragan Simic <dsimic@manjaro.org> Link: https://lore.kernel.org/r/20250120-rock-5c-fan-v1-1-5fb8446c981b@gmail.com Signed-off-by: Heiko Stuebner <heiko@sntech.de>

2025-02-01mm/hugetlb: fix hugepage allocation for interleaved memory nodesRitesh Harjani (IBM)
gather_bootmem_prealloc() assumes the start nid as 0 and size as num_node_state(N_MEMORY). That means in case if memory attached numa nodes are interleaved, then gather_bootmem_prealloc_parallel() will fail to scan few of these nodes. Since memory attached numa nodes can be interleaved in any fashion, hence ensure that the current code checks for all numa node ids (.size = nr_node_ids). Let's still keep max_threads as N_MEMORY, so that it can distributes all nr_node_ids among the these many no. threads. e.g. qemu cmdline ======================== numa_cmd="-numa node,nodeid=1,memdev=mem1,cpus=2-3 -numa node,nodeid=0,cpus=0-1 -numa dist,src=0,dst=1,val=20" mem_cmd="-object memory-backend-ram,id=mem1,size=16G" w/o this patch for cmdline (default_hugepagesz=1GB hugepagesz=1GB hugepages=2): ========================== ~ # cat /proc/meminfo |grep -i huge AnonHugePages: 0 kB ShmemHugePages: 0 kB FileHugePages: 0 kB HugePages_Total: 0 HugePages_Free: 0 HugePages_Rsvd: 0 HugePages_Surp: 0 Hugepagesize: 1048576 kB Hugetlb: 0 kB with this patch for cmdline (default_hugepagesz=1GB hugepagesz=1GB hugepages=2): =========================== ~ # cat /proc/meminfo |grep -i huge AnonHugePages: 0 kB ShmemHugePages: 0 kB FileHugePages: 0 kB HugePages_Total: 2 HugePages_Free: 2 HugePages_Rsvd: 0 HugePages_Surp: 0 Hugepagesize: 1048576 kB Hugetlb: 2097152 kB Link: https://lkml.kernel.org/r/f8d8dad3a5471d284f54185f65d575a6aaab692b.1736592534.git.ritesh.list@gmail.com Fixes: b78b27d02930 ("hugetlb: parallelize 1G hugetlb initialization") Signed-off-by: Ritesh Harjani (IBM) <ritesh.list@gmail.com> Reported-by: Pavithra Prakash <pavrampu@linux.ibm.com> Suggested-by: Muchun Song <muchun.song@linux.dev> Tested-by: Sourabh Jain <sourabhjain@linux.ibm.com> Reviewed-by: Luiz Capitulino <luizcap@redhat.com> Acked-by: David Rientjes <rientjes@google.com> Cc: Donet Tom <donettom@linux.ibm.com> Cc: Gang Li <gang.li@linux.dev> Cc: Daniel Jordan <daniel.m.jordan@oracle.com> Cc: <stable@vger.kernel.org> Signed-off-by: Andrew Morton <akpm@linux-foundation.org>
2025-02-01mm: gup: fix infinite loop within __get_longterm_lockedZhaoyang Huang
We can run into an infinite loop in __get_longterm_locked() when collect_longterm_unpinnable_folios() finds only folios that are isolated from the LRU or were never added to the LRU. This can happen when all folios to be pinned are never added to the LRU, for example when vm_ops->fault allocated pages using cma_alloc() and never added them to the LRU. Fix it by simply taking a look at the list in the single caller, to see if anything was added.

Since nilfs_bmap_lookup_contig() in nilfs_fiemap() calculates its result by being prepared to go through potentially maxblocks == INT_MAX blocks, the value in n may experience an overflow caused by left shift of blkbits. While it is extremely unlikely to occur, play it safe and cast right hand expression to wider type to mitigate the issue.

2025-02-01mm: compaction: use the proper flag to determine watermarksyangge
There are 4 NUMA nodes on my machine, and each NUMA node has 32GB of memory. I have configured 16GB of CMA memory on each NUMA node, and starting a 32GB virtual machine with device passthrough is extremely slow, taking almost an hour. Long term GUP cannot allocate memory from CMA area, so a maximum of 16 GB of no-CMA memory on a NUMA node can be used as virtual machine memory. There is 16GB of free CMA memory on a NUMA node, which is sufficient to pass the order-0 watermark check, causing the __compaction_suitable() function to consistently return true. For costly allocations, if the __compaction_suitable() function always returns true, it causes the __alloc_pages_slowpath() function to fail to exit at the appropriate point. This prevents timely fallback to allocating memory on other nodes, ultimately resulting in excessively long virtual machine startup times. Call trace: __alloc_pages_slowpath if (compact_result == COMPACT_SKIPPED || compact_result == COMPACT_DEFERRED) goto nopage; // should exit __alloc_pages_slowpath() from here We could use the real unmovable allocation context to have __zone_watermark_unusable_free() subtract CMA pages, and thus we won't pass the order-0 check anymore once the non-CMA part is exhausted. There is some risk that in some different scenario the compaction could in fact migrate pages from the exhausted non-CMA part of the zone to the CMA part and succeed, and we'll skip it instead. But only __GFP_NORETRY allocations should be affected in the immediate "goto nopage" when compaction is skipped, others will attempt with DEF_COMPACT_PRIORITY anyway and won't fail without trying to compact-migrate the non-CMA pageblocks into CMA pageblocks first, so it should be fine. After this fix, it only takes a few tens of seconds to start a 32GB virtual machine with device passthrough functionality.

2025-02-01kernel: be more careful about dup_mmap() failures and uprobe registeringLiam R. Howlett
If a memory allocation fails during dup_mmap(), the maple tree can be left in an unsafe state for other iterators besides the exit path. All the locks are dropped before the exit_mmap() call (in mm/mmap.c), but the incomplete mm_struct can be reached through (at least) the rmap finding the vmas which have a pointer back to the mm_struct. Up to this point, there have been no issues with being able to find an mm_struct that was only partially initialised. Syzbot was able to make the incomplete mm_struct fail with recent forking changes, so it has been proven unsafe to use the mm_struct that hasn't been initialised, as referenced in the link below. Although 8ac662f5da19f ("fork: avoid inappropriate uprobe access to invalid mm") fixed the uprobe access, it does not completely remove the race. This patch sets the MMF_OOM_SKIP to avoid the iteration of the vmas on the oom side (even though this is extremely unlikely to be selected as an oom victim in the race window), and sets MMF_UNSTABLE to avoid other potential users from using a partially initialised mm_struct. When registering vmas for uprobe, skip the vmas in an mm that is marked unstable. Modifying a vma in an unstable mm may cause issues if the mm isn't fully initialised.

2025-02-01mm: kmemleak: fix upper boundary check for physical address objectsCatalin Marinas
Memblock allocations are registered by kmemleak separately, based on their physical address. During the scanning stage, it checks whether an object is within the min_low_pfn and max_low_pfn boundaries and ignores it otherwise. With the recent addition of __percpu pointer leak detection (commit 6c99d4eb7c5e ("kmemleak: enable tracking for percpu pointers")), kmemleak started reporting leaks in setup_zone_pageset() and setup_per_cpu_pageset(). These were caused by the node_data[0] object (initialised in alloc_node_data()) ending on the PFN_PHYS(max_low_pfn) boundary. The non-strict upper boundary check introduced by commit 84c326299191 ("mm: kmemleak: check physical address when scan") causes the pg_data_t object to be ignored (not scanned) and the __percpu pointers it contains to be reported as leaks. Make the max_low_pfn upper boundary check strict when deciding whether to ignore a physical address object and not scan it.
