dt-bindings: Remove more cases of 'allOf' containing a '$ref'
Another wack-a-mole pass of killing off unnecessary 'allOf + $ref' usage. json-schema versions draft7 and earlier have a weird behavior in that any keywords combined with a '$ref' are ignored (silently). The correct form was to put a '$ref' under an 'allOf'. This behavior is now changed in the 2019-09 json-schema spec and '$ref' can be mixed with other keywords. The json-schema library doesn't yet support this, but the tooling now does a fixup for this and either way works. This has been a constant source of review comments, so let's change this treewide so everyone copies the simpler syntax. Signed-off-by: Rob Herring <robh@kernel.org> |

dt-bindings: Whitespace clean-ups in schema files
Clean-up incorrect indentation, extra spaces, long lines, and missing EOF newline in schema files. Most of the clean-ups are for list indentation which should always be 2 spaces more than the preceding keyword. Found with yamllint (which I plan to integrate into the checks).

Rationale: Reduces attack surface on kernel devs opening the links for MITM as HTTPS traffic is much harder to manipulate. Deterministic algorithm: For each file: If not .svg: For each line: If doesn't contain `\bxmlns\b`: For each link, `\bhttp://[^# \t\r\n]*(?:\w|/)`: If neither `\bgnu\.org/license`, nor `\bmozilla\.org/MPL\b`: If both the HTTP and HTTPS versions return 200 OK and serve the same content: Replace HTTP with HTTPS.

coredump: add %f for executable filename
The document reads "%e" should be "executable filename" while actually it could be changed by things like pr_ctl PR_SET_NAME. People who uses "%e" in core_pattern get surprised when they find out they get thread name instead of executable filename. This is either a bug of document or a bug of code. Since the behavior of "%e" is there for long time, it could bring another surprise for users if we "fix" the code. So we just "fix" the document. And more, for users who really need the "executable filename" in core_pattern, we introduce a new "%f" for the real executable filename. We already have "%E" for executable path in kernel, so just reuse most of its code for the new added "%f" format.

mm/vmstat: add events for THP migration without split
Add following new vmstat events which will help in validating THP migration without split. Statistics reported through these new VM events will help in performance debugging. 1. THP_MIGRATION_SUCCESS 2. THP_MIGRATION_FAILURE 3. THP_MIGRATION_SPLIT In addition, these new events also update normal page migration statistics appropriately via PGMIGRATE_SUCCESS and PGMIGRATE_FAILURE. While here, this updates current trace event 'mm_migrate_pages' to accommodate now available THP statistics.

mm: proactive compaction
For some applications, we need to allocate almost all memory as hugepages. However, on a running system, higher-order allocations can fail if the memory is fragmented. Linux kernel currently does on-demand compaction as we request more hugepages, but this style of compaction incurs very high latency. Experiments with one-time full memory compaction (followed by hugepage allocations) show that kernel is able to restore a highly fragmented memory state to a fairly compacted memory state within <1 sec for a 32G system. Such data suggests that a more proactive compaction can help us allocate a large fraction of memory as hugepages keeping allocation latencies low. For a more proactive compaction, the approach taken here is to define a new sysctl called 'vm.compaction_proactiveness' which dictates bounds for external fragmentation which kcompactd tries to maintain. The tunable takes a value in range [0, 100], with a default of 20. Note that a previous version of this patch [1] was found to introduce too many tunables (per-order extfrag{low, high}), but this one reduces them to just one sysctl. Also, the new tunable is an opaque value instead of asking for specific bounds of "external fragmentation", which would have been difficult to estimate. The internal interpretation of this opaque value allows for future fine-tuning. Currently, we use a simple translation from this tunable to [low, high] "fragmentation score" thresholds (low=100-proactiveness, high=low+10%). The score for a node is defined as weighted mean of per-zone external fragmentation. A zone's present_pages determines its weight. To periodically check per-node score, we reuse per-node kcompactd threads, which are woken up every 500 milliseconds to check the same. If a node's score exceeds its high threshold (as derived from user-provided proactiveness value), proactive compaction is started until its score reaches its low threshold value. By default, proactiveness is set to 20, which implies threshold values of low=80 and high=90. This patch is largely based on ideas from Michal Hocko [2]. See also the LWN article [3]. Performance data ================ System: x64_64, 1T RAM, 80 CPU threads. Kernel: 5.6.0-rc3 + this patch echo madvise | sudo tee /sys/kernel/mm/transparent_hugepage/enabled echo madvise | sudo tee /sys/kernel/mm/transparent_hugepage/defrag Before starting the driver, the system was fragmented from a userspace program that allocates all memory and then for each 2M aligned section, frees 3/4 of base pages using munmap. The workload is mainly anonymous userspace pages, which are easy to move around. I intentionally avoided unmovable pages in this test to see how much latency we incur when hugepage allocations hit direct compaction. 1. Kernel hugepage allocation latencies With the system in such a fragmented state, a kernel driver then allocates as many hugepages as possible and measures allocation latency: (all latency values are in microseconds) - With vanilla 5.6.0-rc3 percentile latency –––––––––– ––––––– 5 7894 10 9496 25 12561 30 15295 40 18244 50 21229 60 27556 75 30147 80 31047 90 32859 95 33799 Total 2M hugepages allocated = 383859 (749G worth of hugepages out of 762G total free => 98% of free memory could be allocated as hugepages) - With 5.6.0-rc3 + this patch, with proactiveness=20 sysctl -w vm.compaction_proactiveness=20 percentile latency –––––––––– ––––––– 5 2 10 2 25 3 30 3 40 3 50 4 60 4 75 4 80 4 90 5 95 429 Total 2M hugepages allocated = 384105 (750G worth of hugepages out of 762G total free => 98% of free memory could be allocated as hugepages) 2. JAVA heap allocation In this test, we first fragment memory using the same method as for (1). Then, we start a Java process with a heap size set to 700G and request the heap to be allocated with THP hugepages. We also set THP to madvise to allow hugepage backing of this heap. /usr/bin/time java -Xms700G -Xmx700G -XX:+UseTransparentHugePages -XX:+AlwaysPreTouch The above command allocates 700G of Java heap using hugepages. - With vanilla 5.6.0-rc3 17.39user 1666.48system 27:37.89elapsed - With 5.6.0-rc3 + this patch, with proactiveness=20 8.35user 194.58system 3:19.62elapsed Elapsed time remains around 3:15, as proactiveness is further increased. Note that proactive compaction happens throughout the runtime of these workloads. The situation of one-time compaction, sufficient to supply hugepages for following allocation stream, can probably happen for more extreme proactiveness values, like 80 or 90. In the above Java workload, proactiveness is set to 20. The test starts with a node's score of 80 or higher, depending on the delay between the fragmentation step and starting the benchmark, which gives more-or-less time for the initial round of compaction. As t he benchmark consumes hugepages, node's score quickly rises above the high threshold (90) and proactive compaction starts again, which brings down the score to the low threshold level (80). Repeat. bpftrace also confirms proactive compaction running 20+ times during the runtime of this Java benchmark. kcompactd threads consume 100% of one of the CPUs while it tries to bring a node's score within thresholds. Backoff behavior ================ Above workloads produce a memory state which is easy to compact. However, if memory is filled with unmovable pages, proactive compaction should essentially back off. To test this aspect: - Created a kernel driver that allocates almost all memory as hugepages followed by freeing first 3/4 of each hugepage. - Set proactiveness=40 - Note that proactive_compact_node() is deferred maximum number of times with HPAGE_FRAG_CHECK_INTERVAL_MSEC of wait between each check (=> ~30 seconds between retries).

mm: memcg/percpu: per-memcg percpu memory statistics
Percpu memory can represent a noticeable chunk of the total memory consumption, especially on big machines with many CPUs. Let's track percpu memory usage for each memcg and display it in memory.stat. A percpu allocation is usually scattered over multiple pages (and nodes), and can be significantly smaller than a page. So let's add a byte-sized counter on the memcg level: MEMCG_PERCPU_B. Byte-sized vmstat infra created for slabs can be perfectly reused for percpu case.

remoteproc updates for v5.9
This introduces a new "detached" state for remote processors that are deemed to be running at the time Linux boots and the infrastructure for "attaching" to these. It then introduces the support for performing this operation for the STM32 platform. The coredump functionality is moved out from the core file and gains support for an optional mode where the recovery phase awaits the notification from devcoredump that the dump should be released. This allows userspace to grab the coredump in scenarios where vmalloc space is too low for creating a complete copy of the coredump before handing this to devcoredump. A new character device based interface is introduced to allow tying the stoppage of a remote processor to the termination of a user space process. This is useful in situations when such process provides crucial resources/operations for the firmware running on the remote processor. The Texas Instrument K3 driver gains support for the C66x and C71x DSPs. Qualcomm remoteprocs gains support for stashing relocation information in IMEM, to aid post mortem debugging and the crash notification mechanism is generalized to be reusable in cases where loosely coupled drivers needs to know about the status of a remote processor. One such example is the IPA hardware block, which is jointly owned with the modem and migrated to this improved interface. It also introduces a number of bug fixes and debug improvements for the Qualcomm modem remoteproc driver. And it cleans up the inconsistent interface for remoteproc drivers to implement power management. -----BEGIN PGP SIGNATURE----- iQJPBAABCAA5FiEEBd4DzF816k8JZtUlCx85Pw2ZrcUFAl8yKn4bHGJqb3JuLmFu ZGVyc3NvbkBsaW5hcm8ub3JnAAoJEAsfOT8Nma3FwNQQAMH8rbJ1wY+FM5vYfchF IIruKUAuiUYf3Wtx96nRRM81nWQWE0+gh37CGdQ0J+5XMhtVVgHH5cIcTcTqHfAG J8rdkcFP4ntyLPa2qP5tPeMj0rqD/cHvzD10PyrJjvP12i9+0mJGR/nDHRRAhyg1 HMTfq5kQsIRt3SYnHrwzD3nvk+O6aEtyogjDX9VhQ3Qx62pKVLiPCUy4FIZ2XzY2 XvNdITqN1IbqMMEgWNLBrFbU8RDnFZgGUFjuVmy+9SalKifh1s0nmdDxmFihbbhj pltc8mLRabhkkdqctvz6nh85epkqmoA15WL+BTLDVIpQ4zSJxFeRq+yK5m3V5EzZ Ld5ukS3IYaLLFOT1OvwjUVbrSVYnb3SMFI6W2v8J/BouBzFzzfYaq4QmvW4GGPEw MWMoicpmZousVGfUREFkmYj/8XqfgoVZ8gpLVxNDuluFU5swjoAK2FfQet4KCf0d /+A77nWvcRuHFYLv8FAiAxxRY2Dnx8rPnIm8wNd4Nj9Lx7lhkVPRwCgBr4SyXX60 FAGqZmg5S0Q5JUVA1s76n/1jbDywr6+a9ez48izivck1eYqAwSOAtt57Ol4A9tEq OGX8bvnJBXM9mDOV2jRCOr3vfn9Y3kqn8ia20gNsmifUM6RkvvSzz4bdhwd0Aj2H 0PWNiyPI+OKV8L64Q4sASbDR =9cjt -----END PGP SIGNATURE----- Merge tag 'rproc-v5.9' of git://git.kernel.org/pub/scm/linux/kernel/git/andersson/remoteproc Pull remoteproc updates from Bjorn Andersson: "This introduces a new "detached" state for remote processors that are deemed to be running at the time Linux boots and the infrastructure for "attaching" to these.

cpufreq: intel_pstate: Implement passive mode with HWP enabled
Allow intel_pstate to work in the passive mode with HWP enabled and make it set the HWP minimum performance limit (HWP floor) to the P-state value given by the target frequency supplied by the cpufreq governor, so as to prevent the HWP algorithm and the CPU scheduler from working against each other, at least when the schedutil governor is in use, and update the intel_pstate documentation accordingly. Among other things, this allows utilization clamps to be taken into account, at least to a certain extent, when intel_pstate is in use and makes it more likely that sufficient capacity for deadline tasks will be provided. After this change, the resulting behavior of an HWP system with intel_pstate in the passive mode should be close to the behavior of the analogous non-HWP system with intel_pstate in the passive mode, except that the HWP algorithm is generally allowed to make the CPU run at a frequency above the floor P-state set by intel_pstate in the entire available range of P-states, while without HWP a CPU can run in a P-state above the requested one if the latter falls into the range of turbo P-states (referred to as the turbo range) or if the P-states of all CPUs in one package are coordinated with each other at the hardware level. [Note that in principle the HWP floor may not be taken into account by the processor if it falls into the turbo range, in which case the processor has a license to choose any P-state, either below or above the HWP floor, just like a non-HWP processor in the case when the target P-state falls into the turbo range.] With this change applied, intel_pstate in the passive mode assumes complete control over the HWP request MSR and concurrent changes of that MSR (eg. via the direct MSR access interface) are overridden by it.

zonefs: update documentation to reflect zone size vs capacity
Update the zonefs documentation to reflect the difference between a zone's size and it's capacity. The maximum file size in zonefs is the zones capacity, for ZBC and ZAC based devices, which do not have a separate zone capacity, the zone capacity is equal to the zone size.

A set of locking fixes and updates:
- Untangle the header spaghetti which causes build failures in various situations caused by the lockdep additions to seqcount to validate that the write side critical sections are non-preemptible. - The seqcount associated lock debug addons which were blocked by the above fallout. seqcount writers contrary to seqlock writers must be externally serialized, which usually happens via locking - except for strict per CPU seqcounts. As the lock is not part of the seqcount, lockdep cannot validate that the lock is held. This new debug mechanism adds the concept of associated locks. sequence count has now lock type variants and corresponding initializers which take a pointer to the associated lock used for writer serialization. If lockdep is enabled the pointer is stored and write_seqcount_begin() has a lockdep assertion to validate that the lock is held. Aside of the type and the initializer no other code changes are required at the seqcount usage sites. The rest of the seqcount API is unchanged and determines the type at compile time with the help of _Generic which is possible now that the minimal GCC version has been moved up. Adding this lockdep coverage unearthed a handful of seqcount bugs which have been addressed already independent of this. While generaly useful this comes with a Trojan Horse twist: On RT kernels the write side critical section can become preemtible if the writers are serialized by an associated lock, which leads to the well known reader preempts writer livelock. RT prevents this by storing the associated lock pointer independent of lockdep in the seqcount and changing the reader side to block on the lock when a reader detects that a writer is in the write side critical section. - Conversion of seqcount usage sites to associated types and initializers. -----BEGIN PGP SIGNATURE----- iQJHBAABCgAxFiEEQp8+kY+LLUocC4bMphj1TA10mKEFAl8xmPYTHHRnbHhAbGlu dXRyb25peC5kZQAKCRCmGPVMDXSYoTuQEACyzQCjU8PgehPp9oMqWzaX2fcVyuZO QU2yw6gmz2oTz3ZHUNwdW8UnzGh2OWosK3kDruoD9FtSS51lER1/ISfSPCGfyqxC KTjOcB1Kvxwq/3LcCx7Zi3ZxWApat74qs3EhYhKtEiQ2Y9xv9rLq8VV1UWAwyxq0 eHpjlIJ6b6rbt+ARslaB7drnccOsdK+W/roNj4kfyt+gezjBfojGRdMGQNMFcpnv shuTC+vYurAVIiVA/0IuizgHfwZiXOtVpjVoEWaxg6bBH6HNuYMYzdSa/YrlDkZs n/aBI/Xkvx+Eacu8b1Zwmbzs5EnikUK/2dMqbzXKUZK61eV4hX5c2xrnr1yGWKTs F/juh69Squ7X6VZyKVgJ9RIccVueqwR2EprXWgH3+RMice5kjnXH4zURp0GHALxa DFPfB6fawcH3Ps87kcRFvjgm6FBo0hJ1AxmsW1dY4ACFB9azFa2euW+AARDzHOy2 VRsUdhL9CGwtPjXcZ/9Rhej6fZLGBXKr8uq5QiMuvttp4b6+j9FEfBgD4S6h8csl AT2c2I9LcbWqyUM9P4S7zY/YgOZw88vHRuDH7tEBdIeoiHfrbSBU7EQ9jlAKq/59 f+Htu2Io281c005g7DEeuCYvpzSYnJnAitj5Lmp/kzk2Wn3utY1uIAVszqwf95Ul 81ppn2KlvzUK8g== =7Gj+ -----END PGP SIGNATURE----- Merge tag 'locking-urgent-2020-08-10' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip Pull locking updates from Thomas Gleixner: "A set of locking fixes and updates: - Untangle the header spaghetti which causes build failures in various situations caused by the lockdep additions to seqcount to validate that the write side critical sections are non-preemptible. - The seqcount associated lock debug addons which were blocked by the above fallout. seqcount writers contrary to seqlock writers must be externally serialized, which usually happens via locking - except for strict per CPU seqcounts.

f2fs-for-5.9-rc1
In this round, we've added two small interfaces, 1) GC_URGENT_LOW mode for performance, and 2) F2FS_IOC_SEC_TRIM_FILE ioctl for security. The new GC mode allows Android to run some lower priority GCs in background, while new ioctl discards user information without race condition when the account is removed. In addition, some patches were merged to address latency-related issues. We've fixed some compression-related bug fixes as well as edge race conditions. Enhancement: - add GC_URGENT_LOW mode in gc_urgent - introduce F2FS_IOC_SEC_TRIM_FILE ioctl - bypass racy readahead to improve read latencies - shrink node_write lock coverage to avoid long latency Bug fix: - fix missing compression flag control, i_size, and mount option - fix deadlock between quota writes and checkpoint - remove inode eviction path in synchronous path to avoid deadlock - fix to wait GCed compressed page writeback - fix a kernel panic in f2fs_is_compressed_page - check page dirty status before writeback - wait page writeback before update in node page write flow - fix a race condition between f2fs_write_end_io and f2fs_del_fsync_node_entry We've added some minor sanity checks and refactored trivial code blocks for better readability and debugging information. -----BEGIN PGP SIGNATURE----- iQIzBAABCgAdFiEE00UqedjCtOrGVvQiQBSofoJIUNIFAl8xhqMACgkQQBSofoJI UNLYgA//WMoOqBACDuOWwYmgQ8oq4vrH2LOwssZF9/77vEfaHKc+TSq1il54lcUl MPEx7FK54CnfT8VLLR5ByobZFyH9FFeAw4FN4LBhcfE8jh8ysAGjeoZjwfcmJF6R cVKtn8ltUpgH3IEUuPjTiKkVNHfVJxuuL3zHbg1CEl+AkR6NJ/U9kNLwf7ZgPWq2 I0qwyXRlUIEChhyPZB+Y6RsdGjkeievKld56DMCgG73f4yHRO/yBcrfsN875sGdM ALL+mYiunMT6aXcfoiQiAjeImoNajuflI6Zso2Sk8Vl6sBj0QwAuEBF5x1Z5e1mt YVYNuC4ucqsDBKpOqtsPP0MFTC2T5Rr9wWXjqv+9TjN7zvJ8xx+zDWtQxvI2bpqB 4ZRxaJP45aThLYh/SEYDmj+ppyPtfLDeG0HzUkwMmuopf9eg+kxGPjBsZewgkCKg kmMKU0P7deGlkrWLUcz2vm0Lso+ieGm0IeLOQl9/rOLu3IQQFia0Vla7dLDgqF0P sz+udIiBztC3JPEmEZhfayA6P6e1TyWQUdquL08jp+DZD17gPqcaZDhHr62U5rmK 7zoiZqkR03SbNaFhBhhoVOaAVcAnF0pSIgqzkCa3dVXxp1QV+JfD9CGR9NFyiIqB HK5RPFskIUCg0K2LSaAKbyoFWa/fJ8ZD8/CbFWcnXfWzoaaSkmc= =PjaF -----END PGP SIGNATURE----- Merge tag 'f2fs-for-5.9-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/jaegeuk/f2fs Pull f2fs updates from Jaegeuk Kim: "In this round, we've added two small interfaces: (a) GC_URGENT_LOW mode for performance and (b) F2FS_IOC_SEC_TRIM_FILE ioctl for security.
