Both the cs_nsec and the wd_nsec value indicate that the readout interval was circa 14.5 seconds. The observed behaviour is that watchdog checks failed for large readout intervals on 8 NUMA node machines. This indicates that the size of the skew was directly proportinal to the length of the readout interval on those machines. The measured clocksource skew, 668 microseconds, was evaluated against a threshold (the md variable) that is suited for readout intervals of roughly WATCHDOG_INTERVAL, i.e. HZ >> 1, which is 0.5 second. The intention of 2e27e793e280 ("clocksource: Reduce clocksource-skew threshold") was to tighten the threshold for evaluating skew and set the lower bound for the uncertainty_margin of clocksources to twice WATCHDOG_MAX_SKEW. Later in c37e85c135ce ("clocksource: Loosen clocksource watchdog constraints"), the WATCHDOG_MAX_SKEW constant was increased to 125 microseconds to fit the limit of NTP, which is able to use a clocksource that suffers from up to 500 microseconds of skew per second. Both the TSC and the HPET use default uncertainty_margin. When the readout interval gets stretched the default uncertainty_margin is no longer a suitable lower bound for evaluating skew - it imposes a limit that is far stricter than the skew with which NTP can deal. The root causes of the skew being directly proportinal to the length of the readout interval are: * the inaccuracy of the shift/mult pairs of clocksources and the watchdog * the conversion to nanoseconds is imprecise for large readout intervals Prevent this by skipping the current watchdog check if the readout interval exceeds 2 * WATCHDOG_INTERVAL. Considering the maximum readout interval of 2 * WATCHDOG_INTERVAL, the current default uncertainty margin (of the TSC and HPET) corresponds to a limit on clocksource skew of 250 ppm (microseconds of skew per second). To keep the limit imposed by NTP (500 microseconds of skew per second) for all possible readout intervals, the margins would have to be scaled so that the threshold value is proportional to the length of the actual readout interval. As for why the readout interval may get stretched: Since the watchdog is executed in softirq context the expiration of the watchdog timer can get severely delayed on account of a ksoftirqd thread not getting to run in a timely manner. Surely, a system with such belated softirq execution is not working well and the scheduling issue should be looked into but the clocksource watchdog should be able to deal with it accordingly.

[PATCH v6 0/6] PCI: qcom: Add support for OPP

by Krishna chaitanya chundru

This patch adds support for OPP to vote for the performance state of RPMH power domain based upon GEN speed it PCIe got enumerated. QCOM Resource Power Manager-hardened (RPMh) is a hardware block which maintains hardware state of a regulator by performing max aggregation of the requests made by all of the processors. PCIe controller can operate on different RPMh performance state of power domain based up on the speed of the link. And this performance state varies from target to target. It is manadate to scale the performance state based up on the PCIe speed link operates so that SoC can run under optimum power conditions. Add Operating Performance Points(OPP) support to vote for RPMh state based upon GEN speed link is operating. Before link up PCIe driver will vote for the maximum performance state. As now we are adding ICC BW vote in OPP, the ICC BW voting depends both GEN speed and link width using opp-level to indicate the opp entry table will be difficult. In PCIe certain gen speeds like GEN1x2 & GEN2X1 or GEN3x2 & GEN4x1 use same icc bw if we use freq in the opp table to represent the PCIe Gen speed number of PCIe entries can reduced. So going back to use freq in the opp table instead of level. Signed-off-by: Krishna chaitanya chundru <quic_krichai(a)quicinc.com> --- Changes frm v5: - Add ICC BW voting as part of OPP, rebase the latest kernel, and only - either OPP or ICC BW voting will supported we removed the patch to - return eror for icc opp update patch. - As we added the icc bw voting in opp table I am not including reviewed - by tags given in previous patch. - Use opp freq to find opp entries as now we need to include pcie link - also in to considerations. - Add CPU-PCIe BW voting which is not present till now. - Drop PCI: qcom: Return error from 'qcom_pcie_icc_update' as either opp or icc bw - only one executes and there is no need to fail if opp or icc update fails. - Link for v5: https://lore.kernel.org/linux-arm-msm/20231101063323.GH2897@thinkpad/T/ Changes from v4: - Added a separate patch for returning error from the qcom_pcie_upadate and moved opp update logic to icc_update and used a bool variable to update the opp. - Addressed comments made by pavan. changes from v3: - Removing the opp vote on suspend when the link is not up and link is not up and add debug prints as suggested by pavan. - Added dev_pm_opp_find_level_floor API to find the highest opp to vote. changes from v2: - Instead of using the freq based opp search use level based as suggested by Dmitry Baryshkov.

[PATCH net] nfc: nci: free rx_data_reassembly skb on NCI device cleanup

by Fedor Pchelkin

rx_data_reassembly skb is stored during NCI data exchange for processing fragmented packets. It is dropped only when the last fragment is processed or when an NTF packet with NCI_OP_RF_DEACTIVATE_NTF opcode is received. However, the NCI device may be deallocated before that which leads to skb leak. As by design the rx_data_reassembly skb is bound to the NCI device and nothing prevents the device to be freed before the skb is processed in some way and cleaned, free it on the NCI device cleanup.

+ mm-zswap-fix-missing-folio-cleanup-in-writeback-race-path.patch added to mm-hotfixes-unstable branch

by Andrew Morton

The patch titled Subject: mm: zswap: fix missing folio cleanup in writeback race path has been added to the -mm mm-hotfixes-unstable branch. Its filename is mm-zswap-fix-missing-folio-cleanup-in-writeback-race-path.patch This patch will shortly appear at https://git.kernel.org/pub/scm/linux/kernel/git/akpm/25-new.git/tree/patche… This patch will later appear in the mm-hotfixes-unstable branch at git://git.kernel.org/pub/scm/linux/kernel/git/akpm/mm Before you just go and hit "reply", please: a) Consider who else should be cc'ed b) Prefer to cc a suitable mailing list as well c) Ideally: find the original patch on the mailing list and do a reply-to-all to that, adding suitable additional cc's *** Remember to use Documentation/process/submit-checklist.rst when testing your code *** The -mm tree is included into linux-next via the mm-everything branch at git://git.kernel.org/pub/scm/linux/kernel/git/akpm/mm and is updated there every 2-3 working days ------------------------------------------------------ From: Yosry Ahmed <yosryahmed(a)google.com> Subject: mm: zswap: fix missing folio cleanup in writeback race path Date: Thu, 25 Jan 2024 08:51:27 +0000 In zswap_writeback_entry(), after we get a folio from __read_swap_cache_async(), we grab the tree lock again to check that the swap entry was not invalidated and recycled. If it was, we delete the folio we just added to the swap cache and exit. However, __read_swap_cache_async() returns the folio locked when it is newly allocated, which is always true for this path, and the folio is ref'd. Make sure to unlock and put the folio before returning. This was discovered by code inspection, probably because this path handles a race condition that should not happen often, and the bug would not crash the system, it will only strand the folio indefinitely.

[for-linus][PATCH 1/2] tracing/trigger: Fix to return error if failed to alloc snapshot

by Steven Rostedt

From: "Masami Hiramatsu (Google)" <mhiramat(a)kernel.org> Fix register_snapshot_trigger() to return error code if it failed to allocate a snapshot instead of 0 (success). Unless that, it will register snapshot trigger without an error.
