2021-11-10Merge tag 'rproc-v5.16' of ↵Linus Torvalds
git://git.kernel.org/pub/scm/linux/kernel/git/remoteproc/linux Pull remoteproc updates from Bjorn Andersson: "The remoteproc repo is moved to a new path on git.kernel.org, to allow Mathieu push access to the branches. Support for the Mediatek MT8195 SCP was added, the related DeviceTree binding was converted to YAML and MT8192 SCP was documented as well. Amlogic Meson6, Meson8, Meson8b and Meson8m2 has an ARC core to aid in resuming the system after suspend, a new remoteproc driver for booting this core is introduced. A new driver to support the DSP processor found on NXP i.MX8QM, i.MX8QXP, i.MX8MP and i.MX8ULP is added. The Qualcomm modem and TrustZone based remoteproc drivers gains support for the modem in SC7280 and MSM8996 gains support for a missing power-domain. Throughout the Qualcomm drivers, the support for informing the always-on power coprocessor about the state of each remoteproc is reworked to avoid complications related to our use of genpd and the system suspend state. Lastly a number of small fixes are found throughout the drivers and framework" * tag 'rproc-v5.16' of git://git.kernel.org/pub/scm/linux/kernel/git/remoteproc/linux: (39 commits) remoteproc: Remove vdev_to_rvdev and vdev_to_rproc from remoteproc API remoteproc: omap_remoteproc: simplify getting .driver_data remoteproc: qcom_q6v5_mss: Use devm_platform_ioremap_resource_byname() to simplify code remoteproc: Fix a memory leak in an error handling path in 'rproc_handle_vdev()' remoteproc: Fix spelling mistake "atleast" -> "at least" remoteproc: imx_dsp_rproc: mark PM functions as __maybe_unused remoteproc: imx_dsp_rproc: Correct the comment style of copyright dt-bindings: dsp: fsl: Update binding document for remote proc driver remoteproc: imx_dsp_rproc: Add remoteproc driver for DSP on i.MX remoteproc: imx_rproc: Add IMX_RPROC_SCU_API method remoteproc: imx_rproc: Move common structure to header file rpmsg: char: Remove useless include remoteproc: meson-mx-ao-arc: fix a bit test remoteproc: mss: q6v5-mss: Add modem support on SC7280 dt-bindings: remoteproc: qcom: Update Q6V5 Modem PIL binding remoteproc: qcom: pas: Add SC7280 Modem support dt-bindings: remoteproc: qcom: pas: Add SC7280 MPSS support remoteproc: qcom: pas: Use the same init resources for MSM8996 and MSM8998 MAINTAINERS: Update remoteproc repo url dt-bindings: remoteproc: k3-dsp: Cleanup SoC compatible from DT example ...

2021-11-09Documentation/kcov: include types.h in the exampleSebastian Andrzej Siewior
Patch series "kcov: PREEMPT_RT fixup + misc", v2. The last patch in series is follow-up to address the PREEMPT_RT issue within in kcov reported by Clark [1]. Patches 1-3 are smaller things that I noticed while staring at it. Patch 4 is small change which makes replacement in #5 simpler / more obvious. [1] https://lkml.kernel.org/r/20210809155909.333073de@theseus.lan This patch (of 5): The first example code has includes at the top, the following two example share that part. The last example (remote coverage collection) requires the linux/types.h header file due its __aligned_u64 usage. Add the linux/types.h to the top most example and a comment that the header files from above are required as it is done in the second example.

git://git.kernel.org/pub/scm/linux/kernel/git/cxl/cxl Pull cxl updates from Dan Williams: "More preparation and plumbing work in the CXL subsystem. From an end user perspective the highlight here is lighting up the CXL Persistent Memory related commands (label read / write) with the generic ioctl() front-end in LIBNVDIMM. Otherwise, the ability to instantiate new persistent and volatile memory regions is still on track for v5.17. Summary: - Fix support for platforms that do not enumerate every ACPI0016 (CXL Host Bridge) in the CHBS (ACPI Host Bridge Structure). - Introduce a common pci_find_dvsec_capability() helper, clean up open coded implementations in various drivers. - Add 'cxl_test' for regression testing CXL subsystem ABIs. 'cxl_test' is a module built from tools/testing/cxl/ that mocks up a CXL topology to augment the nascent support for emulation of CXL devices in QEMU. - Convert libnvdimm to use the uuid API. - Complete the definition of CXL namespace labels in libnvdimm. - Tunnel libnvdimm label operations from nd_ioctl() back to the CXL mailbox driver. Enable 'ndctl {read,write}-labels' for CXL. - Continue to sort and refactor functionality into distinct driver and core-infrastructure buckets.

2021-11-06kfence: default to dynamic branch instead of static keys modeMarco Elver
We have observed that on very large machines with newer CPUs, the static key/branch switching delay is on the order of milliseconds. This is due to the required broadcast IPIs, which simply does not scale well to hundreds of CPUs (cores). If done too frequently, this can adversely affect tail latencies of various workloads. One workaround is to increase the sample interval to several seconds, while decreasing sampled allocation coverage, but the problem still exists and could still increase tail latencies. As already noted in the Kconfig help text, there are trade-offs: at lower sample intervals the dynamic branch results in better performance; however, at very large sample intervals, the static keys mode can result in better performance -- careful benchmarking is recommended. Our initial benchmarking showed that with large enough sample intervals and workloads stressing the allocator, the static keys mode was slightly better. Evaluating and observing the possible system-wide side-effects of the static-key-switching induced broadcast IPIs, however, was a blind spot (in particular on large machines with 100s of cores). Therefore, a major downside of the static keys mode is, unfortunately, that it is hard to predict performance on new system architectures and topologies, but also making conclusions about performance of new workloads based on a limited set of benchmarks. Most distributions will simply select the defaults, while targeting a large variety of different workloads and system architectures. As such, the better default is CONFIG_KFENCE_STATIC_KEYS=n, and re-enabling it is only recommended after careful evaluation. For reference, on x86-64 the condition in kfence_alloc() generates exactly 2 instructions in the kmem_cache_alloc() fast-path: | ... | cmpl $0x0,0x1a8021c(%rip) # ffffffff82d560d0 <kfence_allocation_gate> | je ffffffff812d6003 <kmem_cache_alloc+0x243> | ... which, given kfence_allocation_gate is infrequently modified, should be well predicted by most CPUs.

This change introduces an aged idle interface to the existing idle sysfs file for zram. When CONFIG_ZRAM_MEMORY_TRACKING is enabled the idle file now also accepts an integer argument. This integer is the age (in seconds) of pages to mark as idle. The idle file still supports 'all' as it always has. This new approach allows for much more control over which pages get marked as idle.

Commit e83a437faa62 ("mm/memory_hotplug: introduce "auto-movable" online policy") introduced a new memory online policy to automatically select a zone for memory blocks to be onlined. It added a way to set the active online policy and tunables for the auto-movable online policy. Follow-up commits tweaked the "auto-movable" policy to also consider memory device details when selecting zones for memory blocks to be onlined. Let's document the new toggles and how the two online policies we have work.

2021-11-06hugetlbfs: extend the definition of hugepages parameter to support node ↵Zhenguo Yao
allocation We can specify the number of hugepages to allocate at boot. But the hugepages is balanced in all nodes at present. In some scenarios, we only need hugepages in one node. For example: DPDK needs hugepages which are in the same node as NIC. If DPDK needs four hugepages of 1G size in node1 and system has 16 numa nodes we must reserve 64 hugepages on the kernel cmdline. But only four hugepages are used. The others should be free after boot. If the system memory is low(for example: 64G), it will be an impossible task. So extend the hugepages parameter to support specifying hugepages on a specific node. For example add following parameter: hugepagesz=1G hugepages=0:1,1:3 It will allocate 1 hugepage in node0 and 3 hugepages in node1.

2021-11-06tools/vm/page_owner_sort.c: count and sort by memZhenliang Wei
When viewing page owner information, we may be more concerned about the total memory rather than the times of stack appears. Therefore, the following adjustments are made: 1. Added the statistics on the total number of pages. 2. Added the optional parameter "-m" to configure the program to sort by memory (total pages). The general output of page_owner is as follows: Page allocated via order XXX, ... PFN XXX ... // Detailed stack Page allocated via order XXX, ... PFN XXX ... // Detailed stack The original page_owner_sort ignores PFN rows, puts the remaining rows in buf, counts the times of buf, and finally sorts them according to the times. General output: XXX times: Page allocated via order XXX, ... // Detailed stack Now, we use regexp to extract the page order value from the buf, and count the total pages for the buf. General output: XXX times, XXX pages: Page allocated via order XXX, ... // Detailed stack By default, it is still sorted by the times of buf; If you want to sort by the pages nums of buf, use the new -m parameter.

2021-11-06hugetlb: support node specified when using cma for gigantic hugepagesBaolin Wang
Now the size of CMA area for gigantic hugepages runtime allocation is balanced for all online nodes, but we also want to specify the size of CMA per-node, or only one node in some cases, which are similar with patch [1]. For example, on some multi-nodes systems, each node's memory can be different, allocating the same size of CMA for each node is not suitable for the low-memory nodes. Meanwhile some workloads like DPDK mentioned by Zhenguo in patch [1] only need hugepages in one node. On the other hand, we have some machines with multiple types of memory, like DRAM and PMEM (persistent memory). On this system, we may want to specify all the hugepages only on DRAM node, or specify the proportion of DRAM node and PMEM node, to tuning the performance of the workloads. Thus this patch adds node format for 'hugetlb_cma' parameter to support specifying the size of CMA per-node. An example is as follows: hugetlb_cma=0:5G,2:5G which means allocating 5G size of CMA area on node 0 and node 2 respectively. And the users should use the node specific sysfs file to allocate the gigantic hugepages if specified the CMA size on that node.

2021-11-06hugetlb: add demote hugetlb page sysfs interfacesMike Kravetz
Patch series "hugetlb: add demote/split page functionality", v4. The concurrent use of multiple hugetlb page sizes on a single system is becoming more common. One of the reasons is better TLB support for gigantic page sizes on x86 hardware. In addition, hugetlb pages are being used to back VMs in hosting environments. When using hugetlb pages to back VMs, it is often desirable to preallocate hugetlb pools. This avoids the delay and uncertainty of allocating hugetlb pages at VM startup. In addition, preallocating huge pages minimizes the issue of memory fragmentation that increases the longer the system is up and running. In such environments, a combination of larger and smaller hugetlb pages are preallocated in anticipation of backing VMs of various sizes. Over time, the preallocated pool of smaller hugetlb pages may become depleted while larger hugetlb pages still remain. In such situations, it is desirable to convert larger hugetlb pages to smaller hugetlb pages. Converting larger to smaller hugetlb pages can be accomplished today by first freeing the larger page to the buddy allocator and then allocating the smaller pages. For example, to convert 50 GB pages on x86: gb_pages=`cat .../hugepages-1048576kB/nr_hugepages` m2_pages=`cat .../hugepages-2048kB/nr_hugepages` echo $(($gb_pages - 50)) > .../hugepages-1048576kB/nr_hugepages echo $(($m2_pages + 25600)) > .../hugepages-2048kB/nr_hugepages On an idle system this operation is fairly reliable and results are as expected. The number of 2MB pages is increased as expected and the time of the operation is a second or two. However, when there is activity on the system the following issues arise: 1) This process can take quite some time, especially if allocation of the smaller pages is not immediate and requires migration/compaction. 2) There is no guarantee that the total size of smaller pages allocated will match the size of the larger page which was freed. This is because the area freed by the larger page could quickly be fragmented. In a test environment with a load that continually fills the page cache with clean pages, results such as the following can be observed: Unexpected number of 2MB pages allocated: Expected 25600, have 19944 real 0m42.092s user 0m0.008s sys 0m41.467s To address these issues, introduce the concept of hugetlb page demotion. Demotion provides a means of 'in place' splitting of a hugetlb page to pages of a smaller size. This avoids freeing pages to buddy and then trying to allocate from buddy. Page demotion is controlled via sysfs files that reside in the per-hugetlb page size and per node directories. - demote_size Target page size for demotion, a smaller huge page size. File can be written to chose a smaller huge page size if multiple are available. - demote Writable number of hugetlb pages to be demoted To demote 50 GB huge pages, one would: cat .../hugepages-1048576kB/free_hugepages /* optional, verify free pages */ cat .../hugepages-1048576kB/demote_size /* optional, verify target size */ echo 50 > .../hugepages-1048576kB/demote Only hugetlb pages which are free at the time of the request can be demoted. Demotion does not add to the complexity of surplus pages and honors reserved huge pages. Therefore, when a value is written to the sysfs demote file, that value is only the maximum number of pages which will be demoted. It is possible fewer will actually be demoted. The recently introduced per-hstate mutex is used to synchronize demote operations with other operations that modify hugetlb pools. Real world use cases -------------------- The above scenario describes a real world use case where hugetlb pages are used to back VMs on x86. Both issues of long allocation times and not necessarily getting the expected number of smaller huge pages after a free and allocate cycle have been experienced. The occurrence of these issues is dependent on other activity within the host and can not be predicted. This patch (of 5): Two new sysfs files are added to demote hugtlb pages. These files are both per-hugetlb page size and per node. Files are: demote_size - The size in Kb that pages are demoted to. (read-write) demote - The number of huge pages to demote. (write-only) By default, demote_size is the next smallest huge page size. Valid huge page sizes less than huge page size may be written to this file. When huge pages are demoted, they are demoted to this size. Writing a value to demote will result in an attempt to demote that number of hugetlb pages to an appropriate number of demote_size pages. NOTE: Demote interfaces are only provided for huge page sizes if there is a smaller target demote huge page size. For example, on x86 1GB huge pages will have demote interfaces. 2MB huge pages will not have demote interfaces. This patch does not provide full demote functionality. It only provides the sysfs interfaces. It also provides documentation for the new interfaces.

2021-11-06Documentation: update pagemap with shmem exceptionsTiberiu A Georgescu
This patch follows the discussions on previous documentation patch threads [1][2]. It presents the exception case of shared memory management from the pagemap's point of view. It briefly describes what is missing, why it is missing and alternatives to the pagemap for page info retrieval in user space. In short, the kernel does not keep track of PTEs for swapped out shared pages within the processes that references them. Thus, the proc/pid/pagemap tool cannot print the swap destination of the shared memory pages, instead setting the pagemap entry to zero for both non-allocated and swapped out pages. This can create confusion for users who need information on swapped out pages. The reasons why maintaining the PTEs of all swapped out shared pages among all processes while maintaining similar performance is not a trivial task, or a desirable change, have been discussed extensively [1][3][4][5]. There are also arguments for why this arguably missing information should eventually be exposed to the user in either a future pagemap patch, or by an alternative tool.

To summarize, it is the unexpected behavior on hitting the kmem limit. This patch moves the deprecation process to the next stage by disallowing to set the kmem limit. In future we might just remove the kmem.limit_in_bytes file completely.
