2021-10-17counter: Add character device interfaceWilliam Breathitt Gray
This patch introduces a character device interface for the Counter subsystem. Device data is exposed through standard character device read operations. Device data is gathered when a Counter event is pushed by the respective Counter device driver. Configuration is handled via ioctl operations on the respective Counter character device node.

2021-10-17counter: Internalize sysfs interface codeWilliam Breathitt Gray
This is a reimplementation of the Generic Counter driver interface. There are no modifications to the Counter subsystem userspace interface, so existing userspace applications should continue to run seamlessly. The purpose of this patch is to internalize the sysfs interface code among the various counter drivers into a shared module. Counter drivers pass and take data natively (i.e. u8, u64, etc.) and the shared counter module handles the translation between the sysfs interface and the device drivers. This guarantees a standard userspace interface for all counter drivers, and helps generalize the Generic Counter driver ABI in order to support the Generic Counter chrdev interface (introduced in a subsequent patch) without significant changes to the existing counter drivers. Note, Counter device registration is the same as before: drivers populate a struct counter_device with components and callbacks, then pass the structure to the devm_counter_register function. However, what's different now is how the Counter subsystem code handles this registration internally. Whereas before callbacks would interact directly with sysfs data, this interaction is now abstracted and instead callbacks interact with native C data types. The counter_comp structure forms the basis for Counter extensions. The counter-sysfs.c file contains the code to parse through the counter_device structure and register the requested components and extensions. Attributes are created and populated based on type, with respective translation functions to handle the mapping between sysfs and the counter driver callbacks. The translation performed for each attribute is straightforward: the attribute type and data is parsed from the counter_attribute structure, the respective counter driver read/write callback is called, and sysfs I/O is handled before or after the driver read/write function is called.

2021-10-16scsi: core: Register sysfs attributes earlierBart Van Assche
A quote from Documentation/driver-api/driver-model/device.rst: "Word of warning: While the kernel allows device_create_file() and device_remove_file() to be called on a device at any time, userspace has strict expectations on when attributes get created. When a new device is registered in the kernel, a uevent is generated to notify userspace (like udev) that a new device is available. If attributes are added after the device is registered, then userspace won't get notified and userspace will not know about the new attributes." Hence register SCSI host sysfs attributes before the SCSI host shost_dev uevent is emitted instead of after that event has been emitted.

2021-10-16clocksource/drivers/arc_timer: Eliminate redefined macro errorRandy Dunlap
In drivers/clocksource/, 3 drivers use "TIMER_CTRL_IE" with 3 different values. Two of them (mps2-timer.c and timer-sp804.c/timer-sp.h) are localized and left unmodifed. One of them uses a shared header file (<soc/arc/timers.h>), which is what is causing the "redefined" warnings, so change the macro name in that driver only. Also change the TIMER_CTRL_NH macro name.

This patch adds DPCM support to audio-graph-card2. It uses "dpcm" node (= D), needs to have routing (= A), need to indicate both FE/BE at links (= B, C). dpcm ports@0 is for FE (= B), port@1 is for BE (= C). remote-endpoint can use both Single/Multi connection.

2021-10-15ASoC: add Audio Graph Card2 driverKuninori Morimoto
We already have audio-graph-card which is Of-graph base of general sound card driver. It is supporting DPCM connection, but was forcibly expanded. Thus, it is very difficult to add new features on it, for example Multi CPU/Codec support, Codec2Codec support, etc. This patch adds more flexible new Audio Graph Card2 driver for it. audio-graph-card and audio-graph-card2 are similar, but don't have full compatibility. Audio Graph Card2 supports very generic connection, but some users want to have its own settings, for example PLL settings, etc. For such case, it has customizing support. In users own driver, it can use Audio Graph Card2 parsing by using audio_graph2_parse_of(), and doing its own customizing. Because Audio Graph Card2 is still under experimental stage, it will indicate such warning when probing, and the DT syntax might be changed.

2021-10-15tcp: md5: Allow MD5SIG_FLAG_IFINDEX with ifindex=0Leonard Crestez
Multiple VRFs are generally meant to be "separate" but right now md5 keys for the default VRF also affect connections inside VRFs if the IP addresses happen to overlap. So far the combination of TCP_MD5SIG_FLAG_IFINDEX with tcpm_ifindex == 0 was an error, accept this to mean "key only applies to default VRF". This is what applications using VRFs for traffic separation want. Signed-off-by: Leonard Crestez <cdleonard@gmail.com> Reviewed-by: David Ahern <dsahern@kernel.org> Signed-off-by: David S.

2021-10-15soc: fsl: dpio: add Net DIM integrationIoana Ciornei
Use the generic dynamic interrupt moderation (dim) framework to implement adaptive interrupt coalescing on Rx. With the per-packet interrupt scheme, a high interrupt rate has been noted for moderate traffic flows leading to high CPU utilization. The dpio driver exports new functions to enable/disable adaptive IRQ coalescing on a DPIO object, to query the state or to update Net DIM with a new set of bytes and frames dequeued.

In DPAA2 based SoCs, the IRQ coalesing support per software portal has 2 configurable parameters: - the IRQ timeout period (QBMAN_CINH_SWP_ITPR): how many 256 QBMAN cycles need to pass until a dequeue interrupt is asserted. - the IRQ threshold (QBMAN_CINH_SWP_DQRR_ITR): how many dequeue responses in the DQRR ring would generate an IRQ.

2021-10-15fq_codel: implement L4S style ce_threshold_ect1 markingEric Dumazet
Add TCA_FQ_CODEL_CE_THRESHOLD_ECT1 boolean option to select Low Latency, Low Loss, Scalable Throughput (L4S) style marking, along with ce_threshold. If enabled, only packets with ECT(1) can be transformed to CE if their sojourn time is above the ce_threshold. Note that this new option does not change rules for codel law. In particular, if TCA_FQ_CODEL_ECN is left enabled (this is the default when fq_codel qdisc is created), ECT(0) packets can still get CE if codel law (as governed by limit/target) decides so. Section 4.3.b of current draft [1] states: b. A scheduler with per-flow queues such as FQ-CoDel or FQ-PIE can be used for L4S. For instance within each queue of an FQ-CoDel system, as well as a CoDel AQM, there is typically also ECN marking at an immediate (unsmoothed) shallow threshold to support use in data centres (see Sec.5.2.7 of [RFC8290]). This can be modified so that the shallow threshold is solely applied to ECT(1) packets. Then if there is a flow of non-ECN or ECT(0) packets in the per-flow-queue, the Classic AQM (e.g. CoDel) is applied; while if there is a flow of ECT(1) packets in the queue, the shallower (typically sub-millisecond) threshold is applied.

But even if we reduce batch sizes, there would still be cases where the estimated count of orphans is beyond the limit, and where tcp_too_many_orphans() has to call the expensive percpu_counter_sum_positive(). One solution is to use plain per-cpu counters, and have a timer to periodically refresh this cache. Updating this cache every 100ms seems about right, tcp pressure state is not radically changing over shorter periods. percpu_counter was nice 15 years ago while hosts had less than 16 cpus, not anymore by current standards. v2: Fix the build issue for CONFIG_CRYPTO_DEV_CHELSIO_TLS=m, reported by kernel test robot <lkp@intel.com> Remove unused socket argument from tcp_too_many_orphans() Fixes: dd24c00191d5 ("net: Use a percpu_counter for orphan_count") Signed-off-by: Eric Dumazet <edumazet@google.com> Reported-by: Stefan Bach <sfb@google.com> Cc: Neal Cardwell <ncardwell@google.com> Acked-by: Neal Cardwell <ncardwell@google.com> Signed-off-by: David S.
