2023-04-22dt-bindings: watchdog: migrate rt2880 text bindings to YAMLSergio Paracuellos
Ralink RT2880 Watchdog bindings used text format, so migrate them to YAML. There are some additions to the binding that were not in the original txt file. This binding is used in RT2880, RT3050, RT3352, RT3883, RT5350, and MT7620 SoCs. To properly align binding with driver code we need to add to the schema 'clocks' and 'resets' properties.

git://git.kernel.org/pub/scm/linux/kernel/git/saeed/linux Saeed Mahameed says: ==================== mlx5-updates-2023-04-20 1) Dragos Improves RX page pool, and provides some fixes to his previous series: 1.1) Fix releasing page_pool for striding RQ and legacy RQ nonlinear case 1.2) Hook NAPIs to page pools to gain more performance. 2) From Roi, Some cleanups to TC and eswitch modules. 3) Maher migrates vnic diagnostic counters reporting from debugfs to a dedicated devlink health reporter Maher Says: =========== net/mlx5: Expose vnic diagnostic counters using devlink Currently, vnic diagnostic counters are exposed through the following debugfs: $ ls /sys/kernel/debug/mlx5/0000:08:00.0/esw/vf_0/vnic_diag/ cq_overrun quota_exceeded_command total_q_under_processor_handle invalid_command send_queue_priority_update_flow nic_receive_steering_discard The current design does not allow the hypervisor to view the diagnostic counters of its VFs, in case the VFs get bound to a VM. In other words, the counters are not exposed for representor interfaces. Furthermore, the debugfs design is inconvenient future-wise, in case more counters need to be reported by the driver in the future. As these counters pertain to vNIC health, it is more appropriate to utilize the devlink health reporter to expose them. Thus, this patchest includes the following changes: * Drop the current vnic diagnostic counters debugfs interface. * Add a vnic devlink health reporter for PFs/VFs core devices, which when diagnosed will dump vnic diagnostic counter values that are queried from FW. * Add a vnic devlink health reporter for the representor interface, which serves the same purpose listed in the previous point, in addition to allowing the hypervisor to view its VFs diagnostic counters, even when the VFs are bounded to external VMs. Example of devlink health reporter usage is: $devlink health diagnose pci/0000:08:00.0 reporter vnic vNIC env counters: total_error_queues: 0 send_queue_priority_update_flow: 0 comp_eq_overrun: 0 async_eq_overrun: 0 cq_overrun: 0 invalid_command: 0 quota_exceeded_command: 0 nic_receive_steering_discard: 0 =========== 4) SW steering fixes and improvements Yevgeny Kliteynik Says: ======================= These short patch series are just small fixes / improvements for SW steering: - Patch 1: Fix dumping of legacy modify_hdr in debug dump to align to what is expected by parser - Patch 2: Have separate threshold for ICM sync per ICM type - Patch 3: Add more info to the steering debug dump - Linux version and device name - Patch 4: Keep track of number of buddies that are currently in use per domain per buddy type ======================= * tag 'mlx5-updates-2023-04-20' of git://git.kernel.org/pub/scm/linux/kernel/git/saeed/linux: net/mlx5: Update op_mode to op_mod for port selection net/mlx5: E-Switch, Remove unused mlx5_esw_offloads_vport_metadata_set() net/mlx5: E-Switch, Remove redundant dev arg from mlx5_esw_vport_alloc() net/mlx5: Include linux/pci.h for pci_msix_can_alloc_dyn() net/mlx5e: RX, Hook NAPIs to page pools net/mlx5e: RX, Fix XDP_TX page release for legacy rq nonlinear case net/mlx5e: RX, Fix releasing page_pool pages twice for striding RQ net/mlx5e: Add vnic devlink health reporter to representors net/mlx5: Add vnic devlink health reporter to PFs/VFs Revert "net/mlx5: Expose vnic diagnostic counters for eswitch managed vports" Revert "net/mlx5: Expose steering dropped packets counter" net/mlx5: DR, Add memory statistics for domain object net/mlx5: DR, Add more info in domain dbg dump net/mlx5: DR, Calculate sync threshold of each pool according to its type net/mlx5: DR, Fix dumping of legacy modify_hdr in debug dump ==================== Link: https://lore.kernel.org/r/20230421013850.349646-1-saeed@kernel.org Signed-off-by: Jakub Kicinski <kuba@kernel.org>

The command `ps -ef ` and `top -c` mark kernel thread by '[' and ']', but sometimes the result is not correct. The task->flags in /proc/$pid/stat is good, but we need remember the value of PF_KTHREAD is 0x00200000 and convert dec to hex. If we have no binary program and shell script which read /proc/$pid/stat, we can know it directly by `cat /proc/$pid/status`.

2023-04-21mm: add new KSM process and sysfs knobsStefan Roesch
This adds the general_profit KSM sysfs knob and the process profit metric knobs to ksm_stat. 1) expose general_profit metric The documentation mentions a general profit metric, however this metric is not calculated. In addition the formula depends on the size of internal structures, which makes it more difficult for an administrator to make the calculation. Adding the metric for a better user experience. 2) document general_profit sysfs knob 3) calculate ksm process profit metric The ksm documentation mentions the process profit metric and how to calculate it. This adds the calculation of the metric. 4) mm: expose ksm process profit metric in ksm_stat This exposes the ksm process profit metric in /proc/<pid>/ksm_stat. The documentation mentions the formula for the ksm process profit metric, however it does not calculate it. In addition the formula depends on the size of internal structures.

2023-04-21ALSA: pcm: rewrite snd_pcm_playback_silence()Oswald Buddenhagen
The auto-silencer supports two modes: "thresholded" to fill up "just enough", and "top-up" to fill up "as much as possible". The two modes used rather distinct code paths, which this patch unifies. The only remaining distinction is how much we actually want to fill. This fixes a bug in thresholded mode, where we failed to use new_hw_ptr, resulting in under-fill. Top-up mode is now more well-behaved and much easier to understand in corner cases. This also updates comments in the proximity of silencing-related data structures.

2023-04-21pds_core: set up device and adminqShannon Nelson
Set up the basic adminq and notifyq queue structures. These are used mostly by the client drivers for feature configuration. These are essentially the same adminq and notifyq as in the ionic driver. Part of this includes querying for device identity and FW information, so we can make that available to devlink dev info. $ devlink dev info pci/0000:b5:00.0 pci/0000:b5:00.0: driver pds_core serial_number FLM18420073 versions: fixed: asic.id 0x0 asic.rev 0x0 running: fw 1.51.0-73 stored: fw.goldfw 1.15.9-C-22 fw.mainfwa 1.60.0-73 fw.mainfwb 1.60.0-57 Signed-off-by: Shannon Nelson <shannon.nelson@amd.com> Acked-by: Jakub Kicinski <kuba@kernel.org> Signed-off-by: David S.

2023-04-20net/mlx5e: Add vnic devlink health reporter to representorsMaher Sanalla
Create a new devlink health reporter for representor interface, which reports the values of representor vnic diagnostic counters when diagnosed. This patch will allow admins to monitor VF diagnostic counters through the representor-interface vnic reporter.

2023-04-20docs: turn off "smart quotes" in the HTML buildJonathan Corbet
We have long disabled the "html_use_smartypants" option to prevent Sphinx from mangling "--" sequences (among others). Unfortunately, Sphinx changed that option to "smartquotes" in the 1.6.6 release, and seemingly didn't see fit to warn about the use of the obsolete option, resulting in the aforementioned mangling returning. Disable this behavior again and hope that the option name stays stable for a while.

Userspace can't easily discover how much of a sleep cycle was spent in a hardware sleep state without using kernel tracing and vendor specific sysfs or debugfs files. To make this information more discoverable, introduce 3 new sysfs files: 1) The time spent in a hw sleep state for last cycle. 2) The time spent in a hw sleep state since the kernel booted 3) The maximum time that the hardware can report for a sleep cycle. All of these files will be present only if the system supports s2idle.
