2021-10-19mlxsw: spectrum_qdisc: Make RED, TBF offloads classfulPetr Machata
Permit offloading qdiscs below RED and TBF. In order to avoid having to implement trivial propagating callbacks for get_prio_bitmap and get_tclass_num, extend mlxsw_sp_qdisc_get_prio_bitmap() and ..._get_tclass_num() to handle the lack of the callback as a cue to forward the request to the parent.

2021-10-19mlxsw: spectrum_qdisc: Validate qdisc topologyPetr Machata
A following patch will enable offloading qdiscs that are deeper than directly under root qdisc. Currently the topology validation consists of demanding a root qdisc position for ETS and PRIO. Since RED and TBF are considered classless, this is enough. In order to prevent some nonsensical combinations when RED and TBF become classful, introduce a more general topology validator.

2021-10-19mlxsw: spectrum_qdisc: Clean stats recursively when priomap changesPetr Machata
On Spectrum, there are no per-TC TX counters. Instead, mlxsw uses per-prio counters and aggregates them according to the priomap. Therefore when priomap changes, the counter base values need to be reset to reflect the change. Previously, this was only done for the sole child qdisc, but a following patch makes RED and TBF classful. Thus apply the request to the whole sub-tree.

2021-10-19mlxsw: spectrum_qdisc: Unify graft validationPetr Machata
Qdisc graft operations have so far been reported at PRIO, ETS and RED, with RED events ignored, because RED was not considered a classful qdisc. A following patch will make mlxsw recognize RED and TBF as classful qdiscs, and thus it is necessary to validate grafting at these qdiscs as well. Rename the existing graft validator to make it clear that it is a generic function, and invoke for RED and TBF graft events as well. Drop the unnecessary PRIO helper and invoke the graft validator directly for PRIO as well.

2021-10-19mlxsw: spectrum_qdisc: Destroy children in mlxsw_sp_qdisc_destroy()Petr Machata
Currently ETS and PRIO are the only offloaded classful qdiscs. Since they are both similar, their destroy handler is the same, and it handles children destruction itself. But now it is possible to do it generically for any classful qdisc. Therefore promote the recursive destruction from the ETS handler to mlxsw_sp_qdisc_destroy(), so that RED and TBF pick it up in follow-up patches.

2021-10-19mlxsw: spectrum_qdisc: Query tclass / priomap instead of caching itPetr Machata
Currently when keeping track of qdiscs, mlxsw notes the TC and priomap corresponding to each qdisc. That is fine currently, as there only ever is one level of qdiscs to update: the direct children of ETS / PRIO. However as deeper structures are made offloadable, ETS would need to update these values for the complete subtree, and interim qdiscs would need to remember to propagate the value. Instead, reverse the responsibility: child qdiscs can ask their parent what their TC and priomap are. ETS / PRIO know the answer right away, or there are defaults for when the root qdisc does not assign them (e.g. when RED is used as root qdisc). When RED and TBF become classful, they will simply forward the request up to their parent.

git://git.kernel.org/pub/scm/linux/kernel/git/saeed/linux Saeed Mahameed says: mlx5-updates-2021-10-18 Maor Maor Gottlieb says: ======================== Use hash to select the affinity port in VF LAG Current VF LAG architecture is based on QP association with a port. QP must be created after LAG is enabled to allow association with non-native port. VM Packets going on slow-path to eSwicth manager (SW path or hairpin) will be transmitted through a different QP than the VM. This means that Different packets of the same flow might egress from different physical ports. This patch-set solves this issue by moving the port selection to be based on the hash function defined by the bond. When the device is moved to VF LAG mode, the driver creates TTC (traffic type classifier) flow tables in order to classify the packet and steer it to the relevant hash function. Similar to what is done in the mlx5 RSS implementation. Each rule in the TTC table, forwards the packet to port selection flow table which has one hash split flow group which contains two "catch all" flow table entries. Each entry point to the relative uplink port. As shown below: ------------------- | FT | TTC rule -> | ----------- | | FG| FTE --|-|-----> uplink of port #1 | | FTE --|-|-----> uplink of port #2 | ----------- | ------------------- Hash split flow group is flow group that created as type of HASH_SPLIT and associated with match definer. The match definer define the fields which included in the hash calculation. The driver creates the match definer according to the xmit hash policy of the bond driver.

New device support ------------------ * adi,adxl313 - New driver and dt bindings for this low power accelerometer. * adi,adxl355 - New driver and dt bindings for this accelerometer. - Later series adds buffer support. * asahi-kasei,ak8975 - Minor additions to driver to support ak09916 * aspeed,aspeed-adc - Substantial rework plus feature additions to add support for the ast2600 including a new dt bindings doc. * atmel,at91_sama5d2 - Rework and support introduced for the sama7g5 parts. * maxim,max31865 - New driver and bindings for this RTD temperature sensor chip. * nxp,imx8qxp - New driver and bindings for the ADC found on the i.MX 8QuadXPlus Soc. * senseair,sunrise - New driver and bindings for this family of carbon dioxide gas sensors. * sensiron,scd4x - New driver and bindings for this carbon dioxide gas sensor. New features ------------ * Output buffer support. Works in a similar fashion to input buffers, but in this case userspace pushes data into the kfifo which is then drained to the device when a trigger occurs. Support added to the ad5766 DAC driver. * Core, devm_iio_map_array_register() to avoid need for devm_add_action_or_reset() based cleanup in fully managed allocation drivers. * Core iio_push_to_buffers_with_ts_unaligned() function to safely handle a few drivers where it really hard to ensure the correct data alignment in an iio_push_to_buffers_with_timestamp() call. Note this uses a bounce buffer so should be avoided whenever possible. Used in the ti,adc108s102, invense,mpu3050 and adi,adis16400. This closes the last known set of drivers with alignment issues at this interface. * maxim,max1027 - Substantial rework to this driver main target of which was supporting use of other triggers than it's own EOC interrupt. - Transfer optimization. * nxp,fxls8962af - Threshold even support including using it as a wakeup source. Cleanups, minor fixes etc ------------------------- Chances of a common type to multiple drivers: * devm_ conversion and drop of .remove() callbacks in: - adi,ad5064 - adi,ad7291 - adi,ad7303 - adi,ad7746 - adi,ad9832 - adi,adis16080 - dialog,da9150-gpadc - intel,mrfld_adc - marvell,berlin2 - maxim,max1363 - maxim,max44000 - nuvoton,nau7802 - st_sensors (includes a lot of rework!) - ti,ads8344 - ti,lp8788 * devm_platform_ioremap_resource() used to reduce boilerplate - cirrus,ep93xx - rockchip,saradc - stm,stm32-dac * Use dev_err_probe() in more places to both not print on deferred probe and ensure a reason for the deferral is available for debug purposes. - adi,ad8801 - capella,cm36651 - linear,ltc1660 - maxim,ds4424 - maxim,max5821 - microchip,mcp4922 - nxp,lpc18xx - onnn,noa1305 - st,lsm9ds0 - st,st_sensors - st,stm32-dac - ti,afe4403 - ti,afe4404 - ti,dac7311 * Drop error returns in SPI and I2C remove() functions as they are ignored and long term plan is to change these all over to returning void. In some cases these patches just make it 'obvious' they always return 0 where it was the case before but not easy to tell. - adi,ad5380 - adi,ad5446 - adi,ad5686 - adi,ad5592r - bosch,bma400 - bosch,bmc150 - fsl,mma7455 - honeywell,hmc5843 - kionix,kxsd9 - maxim,max5487 - meas,ms5611 - ti,afe4403 Driver specific changes * adi,ad5770r - Bring driver inline with documented bindings. * adi,ad7746 - Trivial style fix * adi,ad7949 - Express some magic values as the underlying parts via new #defines. - Make it work with SPI controllers that don't support 14 or 16 bit messages - Support selection of voltage reference from dt including expanding the dt-bindings to cover this new functionality. * adi,ad799x - Implement selection of external reference voltage on AD7991, AD7995 and AD7999. - Add missing dt-bindings doc for devices supported by this driver. * adi,adislib - Move interrupt startup to better location in startup flow. - Handle devices that cannot mask/unmask the drdy pin and must instead mask at the interrupt controller. Applies to the adis16460 and adis16475 from which we then drop equivalent code. * adi,ltc2983 - Add support for optional reset pin. - Fail to probe if no channels specified in dt binding. * asahi-kasei,ak8975 - dt-binding additions of missing vid-supply regulator. * aspeed,aspeed-adc - Typo fix. * fsl,mma7660 - Mark acpi_device_id table __maybe_unused to avoid build warning. * fsl,imx25-gcq - Avoid initializing regulators that aren't used. * invensense,mpu3050 - Drop a dead protection against a clash with the old input driver. * invensense,mpu6050 - Rework code to not use strcpy() and hence avoid possibility of wrong sized buffers. Note this wasn't a bug, but the new code is a lot more readable. - Mark acpi_device_id table __maybe_unused to avoid build warning. * kionix,kxcjk1013 - dt-binding addition to note it supports interrupts. * marvell,berlin2-adc - Enable COMPILE_TEST building. * maxim,max1027 - Avoid returning success in an error path. * nxp,imx8qxp - Fix warning when runtime pm not enabled via __maybe_unused. * ricoh,rn5t618 - Use the new devm_iio_map_array_register() instead of open coding the same. * samsung,exynos_adc - Improve kconfig help text. * st,lsm6dsx - Move max_fifo_size into the fifo_ops structure where the other configuration parameters are found. * st,st_sensors: - Reorder to ensure we turn the power off after removing userspace interfaces. * senseair,sunrise - Add missing I2C dependency. * ti,twl6030 - Small code tidy up. * tag 'iio-for-5.16a-split-take4' of https://git.kernel.org/pub/scm/linux/kernel/git/jic23/iio: (148 commits) iio: imx8qxp-adc: mark PM functions as __maybe_unused iio: pressure: ms5611: Make ms5611_remove() return void iio: potentiometer: max5487: Don't return an error in .remove() iio: magn: hmc5843: Make hmc5843_common_remove() return void iio: health: afe4403: Don't return an error in .remove() iio: dac: ad5686: Make ad5686_remove() return void iio: dac: ad5592r: Make ad5592r_remove() return void iio: dac: ad5446: Make ad5446_remove() return void iio: dac: ad5380: Make ad5380_remove() return void iio: accel: mma7455: Make mma7455_core_remove() return void iio: accel: kxsd9: Make kxsd9_common_remove() return void iio: accel: bmi088: Make bmi088_accel_core_remove() return void iio: accel: bmc150: Make bmc150_accel_core_remove() return void iio: accel: bma400: Make bma400_remove() return void drivers:iio:dac:ad5766.c: Add trigger buffer iio: triggered-buffer: extend support to configure output buffers iio: kfifo-buffer: Add output buffer support iio: Add output buffer support iio: documentation: Document scd4x calibration use drivers: iio: chemical: Add support for Sensirion SCD4x CO2 sensor ...
2021-10-19counter: drop chrdev_lockDavid Lechner
This removes the chrdev_lock from the counter subsystem. This was intended to prevent opening the chrdev more than once. However, this doesn't work in practice since userspace can duplicate file descriptors and pass file descriptors to other processes. Since this protection can't be relied on, it is best to just remove it.

2021-10-19ARM: 9119/1: amba: Properly handle device probe without IRQ domainWang Kefeng
of_amba_device_create() uses irq_of_parse_and_map() to translate a DT interrupt specification into a Linux virtual interrupt number. But it doesn't properly handle the case where the interrupt controller is not yet available, eg, when pl011 interrupt is connected to MBIGEN interrupt controller, because the mbigen initialization is too late, which will lead to no IRQ due to no IRQ domain found, log is shown below, "irq: no irq domain found for uart0 !" use of_irq_get() to return -EPROBE_DEFER as above, and in the function amba_device_try_add()/amba_device_add(), it will properly handle in such case, also return 0 in other fail cases to be consistent as before.

On Windows systems, ASUS laptops uses the "turn display off" key (usually fn+f6) to turn both display and keyboard backlit off. On Linux systems, this key has no effect at all since most desktop enviroments don't deal with KEY_DISPLAY_OFF. By mapping it to KEY_SCREENLOCK instead, would enable desktop environments to handle this key as a screen lock intent from the user, out of the box.

2021-10-19HID: apple: Bring back flag for Apple tilde key quirkAlex Henrie
Some Apple ISO keyboards have a quirk where the backtick/tilde key is swapped with the less-than/greater-than key. Unfortunately, there is no perfectly reliable way to detect whether a keyboard has the quirk or not, but the quirk appears to only be present on models that support Bluetooth, and the affected keyboards usually report country code 13 in the HID descriptor. Therefore, the best we can do is to change /sys/module/hid_apple/parameters/iso_layout to a ternary: 0 = Not ISO or ISO and not quirky 1 = ISO and quirky -1 = Guess based on product ID and country code Table of keyboards that José, Julian and I have tested: Product Model Shape Labels Bus Country Quirky ========================================================= 05ac:0201 M2452 ANSI Usonian USB 0 No 05ac:020b A1048 ANSI Usonian USB 0 No 05ac:020c A1048 ISO Québécois USB 13 No 05ac:0221 A1243 ISO Norwegian USB 13 No 05ac:0221 A1243 ISO Portuguese USB 13 No 05ac:0221 A1243 ISO Swedish USB 13 No 05ac:0221 A1243 ISO Swiss USB 13 No 05ac:022c A1255 ANSI Usonian BT 33 No 05ac:022d A1255 ISO Hebrew BT 13 Yes 05ac:022d A1255 ISO Québécois BT 13 Yes 05ac:022d A1255 ISO Spanish BT 13 Yes 05ac:023a A1314 ISO Russian BT 13 Yes 05ac:023a A1314 ISO Swiss BT 13 Yes 05ac:024f A1243 ANSI Usonian USB 0 No 05ac:0250 A1243 ISO British USB 13 No 05ac:0250 A1243 ISO German USB 13 No 05ac:0250 A1243 ISO Italian USB 13 No 05ac:0250 A1243 ISO Québécois USB 13 No 05ac:0251 A1243 JIS Japanese USB 15 No 05ac:0255 A1314 ANSI Usonian BT 33 No 05ac:0255 A1314 ANSI Taiwanese BT 33 No 05ac:0255 A1314 ANSI Thai BT 33 No 05ac:0256 A1314 ISO Arabic BT 13 Yes 05ac:0256 A1314 ISO French BT 13 Yes 05ac:0256 A1314 ISO German BT 13 Yes 05ac:0256 A1314 ISO Norwegian BT 13 Yes 05ac:0256 A1314 ISO Spanish BT 13 Yes 05ac:0256 A1314 ISO Swiss BT 13 Yes 05ac:0257 A1314 JIS Japanese BT 15 No 05ac:0267 A1644 ANSI Usonian USB 33 No 004c:0267 A1644 ANSI Usonian BT 0 No 05ac:0267 A1644 ISO British USB 13 Yes 004c:0267 A1644 ISO British BT 0 Yes 05ac:0267 A1644 ISO Finnish USB 13 Yes 004c:0267 A1644 ISO Finnish BT 0 Yes 05ac:0267 A1644 ISO Québécois USB 13 Yes 004c:0267 A1644 ISO Québécois BT 0 Yes 05ac:0267 A1644 ISO Spanish USB 13 Yes 004c:0267 A1644 ISO Spanish BT 0 Yes 05ac:0267 A1644 ISO Swiss USB 13 Yes 004c:0267 A1644 ISO Swiss BT 0 Yes 05ac:0267 A1644 JIS Japanese USB 15 No 004c:0267 A1644 JIS Japanese BT 0 No 05ac:029c A2450 ANSI Usonian USB 33 No 004c:029c A2450 ANSI Usonian BT 0 No 05ac:029c A2450 ISO Spanish USB 13 Yes 004c:029c A2450 ISO Spanish BT 0 Yes 05ac:029c A2450 JIS Japanese USB 15 No 004c:029c A2450 JIS Japanese BT 0 No Reported-by: José Expósito <jose.exposito89@gmail.com> Tested-by: José Expósito <jose.exposito89@gmail.com> Tested-by: Julian Weigt <juw@posteo.de> Signed-off-by: Alex Henrie <alexhenrie24@gmail.com> Signed-off-by: Jiri Kosina <jkosina@suse.cz>

2021-10-19platform/mellanox: mlxreg-lc: Add initial support for Nvidia line card devicesVadim Pasternak
Provide support for the Nvidia MSN4800-XX line cards for MSN4800 Ethernet modular switch system, providing a high performance switching solution for Enterprise Data Centers (EDC) for building Ethernet based clusters, High-Performance Computing (HPC) and embedded environments. Initial version provides support for line card type MSN4800-C16. This type of line card is equipped with: - Lattice CPLD device, used for system and ports control. - four Nvidia gearbox devices, used for port splitting. - FPGA device, used for gearboxes management. - 16x100G QSFP28 ports. - hotpswap controllers, voltage regulators, analog-to-digital convertors, nvram devices. - status LED. During initialization driver creates: - line card's I2C tree through "i2c-mux-mlxcpd" driver. - line card's LED objects through "leds-mlxreg" driver. - line card's CPLD register space input / output "hwmon" attributes for line control and monitoring through "mlxreg-io" driver. These attributes provide CPLD and FPAG versioning, control for upgradable components burning, NVRAM devices write protection, line card revision, line card power consuming, line card reset cause indication, etcetera. Lattice CPLD device and nvram devices are feeding from auxiliary power domain and accessible, when line card is powered off. These devices are connected by line card driver probing routine, invoked after line card security verification is done by hardware and event lc#n_verified is received for line card located in slot #n. Gearboxes, FPGA, hotpswap controllers, voltage regulators, analog-to-digital convertors are feeding from main power domain. These devices are connected after power good event "lc#n_powered" is received for line card located in slot #n. The driver 'mlxreg-lc' is driven by 'mlxreg-hotplug' driver following relevant "hotplug" events.

Extend logic for hotplug devices creation and removing according to the action associated with the hotplug device description. Previously hotplug driver was capable to attach / de-attach upon hotplug events only I2C devices handled by simple I2C drivers. Now it should be able to attach also devices handled by the platform drivers. The motivation is to allow transition of platform data like: - system interrupt line number, sharing with 'mlxreg-hotplug' to underlying hotplug devices. - shared register map of programmable devices on main board to underlying hotplug devices.

2021-10-19platform/x86: mlx-platform: Add initial support for new modular systemVadim Pasternak
Add initial chassis management support for Nvidia modular Ethernet switch systems MSN4800, providing a high performance switching solution for Enterprise Data Centers (EDC) for building Ethernet based clusters, High-Performance Computing (HPC) and embedded environments. This system could be equipped with the different types of replaceable line cards and management board. The first system flavor will support the line card type MSN4800-C16 equipped with Lattice CPLD devices aimed for system and ASIC control, one Nvidia FPGA for gearboxes (PHYs) management, and four Nvidia gearboxes for the port control and with 16x100GbE QSFP28 ports and also with various devices for electrical control. The system is equipped with eight slots for line cards, four slots for power supplies and six slots for fans. It could be configured as fully populated or with even only one line card. The line cards are hot-pluggable. In the future when more line card flavors are to be available (for example line cards with 8x200Gb Eth port, with 4x400 Eth ports, or with some kind of smart cards for offloading purpose), any type of line card could be inserted at any slot. The system is based on Nvidia Spectrum-3 ASIC. The switch height is 4U and it fits standard rack size. System could be configured as fully populated or with even only one line card. The line cards are hot-pluggable. Line cards are connected to the chassis through I2C interface for the chassis management operations and through PCIe for the networking operations. Future line cards could be connected to the chassis through InfiniBand fabric, instead of PCIe. The first type of line card supports 16x100GbE QSFP28 Ethernet ports. Those line cards equipped with the programmable devices aimed for system control of Nvidia Ethernet switch ASIC control, Nvidia FPGA, Nvidia gearboxes (PHYs). The next coming card generations are supposed to support: - Line cards with 8x200Gbe QSFP28 Ethernet ports. - Line cards with 4x400Gbe QSFP-DD Ethernet ports. - Smart cards equipped with Nvidia ARM CPU for offloading and for fast access to the storage (EBoF). - Fabric cards for inter-connection. The basic system initialization flow with input signals from the programmable device to kernel hotplug driver and with OS response to some of these signals is depicted below. lc#n_prsnt *-> Input: line card presence in/out events. Informational event. Required action - 'udev' event generation for logging. lc#n_verified *-> Input: line card verification status events coming after line card security signature validation by hardware. Required action - connect line card driver and initialized line card devices feeding from system auxiliary power domain. lc#n_pwr <-* Output: line card power on / off from OS. Action should be performed by platform power management driver. lc#n_powered *-> Input: line card power on/off events coming after line card "power good" on/off events, mean that line card power up sequence has been successfully completed or line card "power good" status has been dropped. Required action - connect line card devices feeding from system main power domain. lc#n_synced *-> Input: line card synchronization events, coming after hardware-firmware synchronization handshake. Required action - to enable line card, in case lc#n_ready has been received before. lc#n_ready *-> Input: line card ready events, indicating line card PHYs ready / unready states. Required action - enable line card, in case lc#n_synced has been received before. lc#n_enable <-* Output: line card enable from OS - release FPGA and PHYs line card devices from reset state. Action should be performed by platform power management driver. lc#n_active *-> Input: when line card "active event" is received for particular line card, its network, hardware monitoring and thermal interfaces should be configured according to the configuration obtained from the firmware. When opposite "inactive event" is received all the above interfaces should be teared down. Required action - connect / disconnect the above line card interfaces through ASIC I2C chassis management driver. For initial support: - Define new system type 'VMOD0011' to support new modular system. - Provide initial platform configuration for new system type. - Extend the registers definitions. - Add support for modular system registers related to line card specific events - insertion/removal, power on/off, verification and activation. - Add hotplug configuration for the above events. - Add configurations for hotplug actions for the modular system.
