2021-06-09net/mlx5: Bridge, support pvid and untagged vlan configurationsVlad Buslov1-0/+8
Implement support for pushing vlan header into untagged packet on ingress of port that has pvid configured and support for popping vlan on egress of port that has the matching vlan configured as untagged. To support such configurations packet reformat contexts of {INSERT|REMOVE}_HEADER types are created per such vlan and saved to struct mlx5_esw_bridge_vlan which allows all FDB entries on particular vlan to share single packet reformat instance. When initializing FDB entries with pvid or untagged vlan type set its mlx5_flow_act->pkt_reformat action accordingly. Flush all flows when removing vlan from port. This is necessary because even though software bridge removes all FDB entries before removing their vlan, mlx5 bridge implementation deletes their corresponding flow entries from hardware in asynchronous workqueue task, which will cause firmware error if vlan packet reformat context is deleted before all flows that point to it.

2021-06-09net/mlx5: Bridge, handle FDB eventsVlad Buslov1-0/+15
Hardware supported by mlx5 driver doesn't provide learning and requires the driver to emulate all switch-like behavior in software. As such, all packets by default go through miss path, appear on representor and get to software bridge, if it is the upper device of the representor. This causes bridge to process packet in software, learn the MAC address to FDB and send SWITCHDEV_FDB_ADD_TO_DEVICE event to all subscribers. In order to offload FDB entries in mlx5, register switchdev notifier callback and implement support for both 'added_by_user' and dynamic FDB entry SWITCHDEV_FDB_ADD_TO_DEVICE events asynchronously using new mlx5_esw_bridge_offloads->wq ordered workqueue. In workqueue callback offload the ingress rule (matching FDB entry MAC as packet source MAC) and egress table rule (matching FDB entry MAC as destination MAC). For ingress table rule also match source vport to ensure that only traffic coming from expected bridge port is matched by offloaded rule. Save all the relevant FDB entry data in struct mlx5_esw_bridge_fdb_entry instance and insert the instance in new mlx5_esw_bridge->fdb_list list (for traversing all entries by software ageing implementation in following patch) and in new mlx5_esw_bridge->fdb_ht hash table for fast retrieval. Notify the bridge that FDB entry has been offloaded by sending SWITCHDEV_FDB_OFFLOADED notification. Delete FDB entry on reception of SWITCHDEV_FDB_DEL_TO_DEVICE event.

2021-06-09cxl/acpi: Introduce cxl_decoder objectsDan Williams1-0/+70
A cxl_decoder is a child of a cxl_port. It represents a hardware decoder configuration of an upstream port to one or more of its downstream ports. The decoder is either represented in CXL standard HDM decoder registers (see CXL 2.0 section 8.2.5.12 CXL HDM Decoder Capability Structure), or it is a static decode configuration communicated by platform firmware (see the CXL Early Discovery Table: Fixed Memory Window Structure). The firmware described and hardware described decoders differ slightly leading to 2 different sub-types of decoders, cxl_decoder_root and cxl_decoder_switch. At the root level the decode capabilities restrict what can be mapped beneath them. Mid-level switch decoders are configured for either acclerator (type-2) or memory-expander (type-3) operation, but they are otherwise agnostic to the type of memory (volatile vs persistent) being mapped. Here is an example topology from a single-ported host-bridge environment without CFMWS decodes enumerated. /sys/bus/cxl/devices/root0 ├── devtype ├── dport0 -> ../../../LNXSYSTM:00/LNXSYBUS:00/ACPI0016:00 ├── port1 │   ├── decoder1.0 │   │   ├── devtype │   │   ├── locked │   │   ├── size │   │   ├── start │   │   ├── subsystem -> ../../../../../../bus/cxl │   │   ├── target_list │   │   ├── target_type │   │   └── uevent │   ├── devtype │   ├── dport0 -> ../../../../pci0000:34/0000:34:00.0 │   ├── subsystem -> ../../../../../bus/cxl │   ├── uevent │   └── uport -> ../../../../LNXSYSTM:00/LNXSYBUS:00/ACPI0016:00 ├── subsystem -> ../../../../bus/cxl ├── uevent └── uport -> ../../ACPI0017:00 Reviewed-by: Jonathan Cameron <Jonathan.Cameron@huawei.com> Link: https://lore.kernel.org/r/162325695128.2293823.17519927266014762694.stgit@dwillia2-desk3.amr.corp.intel.com Signed-off-by: Dan Williams <dan.j.williams@intel.com>

On ACPI systems the top-most logical downstream ports in the hierarchy are the host bridges (ACPI0016 devices) that decode the memory windows described by the CXL Early Discovery Table Fixed Memory Window Structures (CEDT.CFMWS).

2021-06-09cxl/acpi: Introduce the root of a cxl_port topologyDan Williams2-0/+26
While CXL builds upon the PCI software model for enumeration and endpoint control, a static platform component is required to bootstrap the CXL memory layout. Similar to how ACPI identifies root-level PCI memory resources, ACPI data enumerates the address space and interleave configuration for CXL Memory. In addition to identifying host bridges, ACPI is responsible for enumerating the CXL memory space that can be addressed by downstream decoders. This is similar to the requirement for ACPI to publish resources via the _CRS method for PCI host bridges. Specifically, ACPI publishes a table, CXL Early Discovery Table (CEDT), which includes a list of CXL Memory resources, CXL Fixed Memory Window Structures (CFMWS). For now, introduce the core infrastructure for a cxl_port hierarchy starting with a root level anchor represented by the ACPI0017 device. Follow on changes model support for the configurable decode capabilities of cxl_port instances, i.e. CXL switch support.

Jonathan writes: 1st set of new IIO/counter device support, features and cleanup for 5.14 There are a couple of large cleanup sets in here alongside a number of new drivers. Note an immutable branch merged to add a stub for i2c_verify_client() as needed to avoid a build issue in the fxls8962af driver as a result of a workaround for a device errata that only applies when i2c interface is used. Counters ======== New device support * intel,quadrature encoder peripheral found on Elkhart Lake platforms. - New driver. IIO === New device support * amstaos,tsl2591 ambient light sensor. - New driver + bindings - Follow up fix to ensure some local variables are suitable for error handling. * fsl,fxls8962af + fsl,fxls8964af accelerometers - New driver + bindings - Includes an errata work around that cause a build bot failure fixed by adding a stub to i2c. * kionix,kxcjk-1013 - Add support for KX023-1025 device. Mostly a different register map that needed to be supported. * murata,sca3300 accelerometer - New driver + bindings * st,lsm9ds0 IMU - Rework of st,sensors driver to cleanly support this new glue driver that enables the two parts of the LSM9DS0. * ti,tsc2046 touchscreen controller ADC. - New driver. Intent here is to use this with existing IIO consumer drivers such as resistive-adc-touch. - Follow up fix to avoid an issue with unsigned subtraction in error check. * ti,tmp117 digital temperature sensor - New driver + bindings Features * adi,ad5755 - Add missing dt-binding doc * adi,ad7298 - Add ACPI ID used on Intel Galileo Gen 1 boards. - Add missing dt-binding doc * adi,ad7476 - Add missing dt-binding doc * adi,ad7746 - Add missing dt-binding doc for this driver that will hopefully move out of staging shortly. Update staging driver to use the binding instead of platform data. * adi,adis16201 + adis16209 - Add missing dt-binding doc * adi,adis16480 - Support burst mode for adis16495 and adis16497 parts. * bosch,bma220 - Add missing dt-binding doc * fsl,mma7455 - Add missing dt-binding doc * iio-rescale - Support handling of processed channels from provider. Some ADCs require (typically non linear) calibration functions to be applied, and so provide only IIO_CHAN_INFO_PROCESSED read back. They can be used as providers to the iio-rescale driver which needs to handle them somewhat differently from IIO_CHAN_INFO_RAW * sensiron,sps30 - Support the serial interface. Note this required significant refactoring of existing driver. * st,st-sensors - Add mount matrix support for normal dt-binding whilst continuing to support the odd ACPI approach for accelerometers. * ti,dac082s085 + similar - Add missing dt-binding doc * trivial-devices - add entries for - memsic,mx4005, memsic,mx6255 and memsic,mxc6655 - sensortek,stk8312 and sensortek,stk8ba50 Cleanup / minor fixes * core - Use devm_add_action_or_reset() to replace boilerplate in several driver and core IIO devm_* functions. - Fix an error path issue introduced by above, that could return an error pointer rather than the expected null from dev_iio_device_alloc() - Move more IIO internals related fields from struct iio_dev to struct iio_dev_opaque. - Drop unused final update of in_loc in demux setup. * Docs - Move some docs from driver specific to core dos to avoid replication of names which the documentation builder does not allow. Note this means adding a few device specific notes to the general docs to cover the more unusual uses of the ABI. - ABI: Move old buffer/* and scan_elements/* docs to obsolete as now we have the bufferX/* variant. Not we are not getting rid of these interfaces, just encouraging new code to use the new interface. * IIO wide: - Tidy up new cases of dev.parent etc being set in drivers as the core now does it. - Fix more cases of possible miss-aligned buffers when passed to iio_push_to_buffers_with_timestamp(). Note we only have one known instance of anyone seeing this bug actually happening, so this has been a low priority cleanup effort for several cycles. - sysfs_emit() used in more drivers. - Runtime pm tidy up and use of pm_runtime_resume_and_get() - Buffer alignment fixes as iio_push_to_buffers_with_timestamp requires that the timestamp when inserted by naturally aligned + consumers can assume that all fields are naturally aligned. Part of a long running effort, with at least 2 more series to come tackling additional variants. - Stop specifying "mount-matrix" property name in every lookup of the mount matrix from firmware by hard coding it in the core. * adi,ad7476 - Handle the variety of different regulators used by the parts supported by this driver (came up in dt-binding review) * adi,ad7746 - Trivial drop of if (ret) return ret; return 0; pattern - Tidy up comments - Pull capdac setup out to own function. * adi,ad7766 - Trivial drop of if (ret) return ret; return 0; pattern * adi,adis - Avoid returning error codes in interrupt handlers. - Handle a failure in spi_write in the trigger handler. - Rework to add updating of device page after changing it. - Don't push data to IIO buffers when read failed. - Add configuration of burst max speed to core avoid handling this in each driver. - Use the adis_dev_lock() helper in adis16260 and adis16136 drivers. - Excessive includes cleanup via include-what-you-use static checker after zero day highlighted that these needed updating. * afe - Amend binding to add #io-channel-cells, thus allowing this IIO consumer to also be an IIO provider. * aosong,am2315 - Drop ACPI id. Unlikely this one is in the wild and it isn't valid ACPI naming. * bosch,bma180 - Adding missing bandwidth settings (500, 1000 Hz) * bosch,bme680 - Drop ACPI id. Unlikely this one is in the wild and it isn't valid ACPI naming. * ep93xx_adc, - Drop a redundant error print. * maxim,max118 - Convert remainder of probe() to devm_ managed functions. - Avoid some repeated jumping back and forth between iio_dev and spi structures. * maxim,max11100 - Use get_unaligned_be16() instead of open coding. - Convert remainder of probe() to devm_ managed functions. * samsung,exynos_adc - Unused error value dropped. * sensiron,sgp30 - Drop use of %hx in favor of %x and letting the normal type conversion work. * sensortek,stk8312 - Add lowercase device id and note uppercase version deprecated. - Drop ACPI id. Unlikely this one is in the wild and it isn't valid ACPI naming. * sprx,sc72xx_adc - add MODULE_DEVICE_TABLE * st,lsm6dsx - Fix docs of valid ODRs * st,sensors - dt-binding rework. Two efforts on this crossed in a previous cycle so this update cherry picks the best of the two yaml conversions. - Don't copy the channel spec array as now ext_info is no longer modified. * st,stm32-adc - tidy up some docs that were marked as kernel-doc but aren't. * ti,adc081c, ti,adc0832, ti,adc108s102 and ti,adc161s626 - Convert remainder of probe() functions to devm_ managed functions to simplify error handing and remove paths. * tag 'iio-for-5.14a' of https://git.kernel.org/pub/scm/linux/kernel/git/jic23/iio: (171 commits) i2c: core: Add stub for i2c_verify_client() if !CONFIG_I2C iio: adis: Cleanout unused headers iio: accel: bma180: Add missing 500 Hz / 1000 Hz bandwidth counter: Add support for Intel Quadrature Encoder Peripheral staging: iio: cdc: ad7746: extract capac setup to own function staging: iio: cdc: ad7746: clean up probe return staging: iio: cdc: ad7746: remove ordinary comments iio: adc: ti-adc161s626: Use devm managed functions for all of probe. iio: adc: ti-adc108s102: Use devm managed functions for all of probe() iio: adc: ti-adc0832: Use devm managed functions for all of probe() iio: adc: ti-adc081c: Use devm managed functions for all of probe() iio: adc: max1118: Avoid jumping back and forth between spi and iio structures iio: adc: max1118: Use devm_ managed functions for all of probe iio: adc: max11100: Use devm_ functions for rest of probe() iio: adc: max11100: Use get_unaligned_be16() rather than opencoding. iio: chemical: sgp30: Drop use of %hx in format string. iio: gyro: st_gyro: Support mount matrix iio: magnetometer: st_magn: Support mount matrix iio: accel: st_sensors: Stop copying channels iio: accel: st_sensors: Support generic mounting matrix ...
2021-06-09usb: gadget: u_audio: add real feedback implementationRuslan Bilovol2-0/+2
This adds interface between userspace and feedback endpoint to report real feedback frequency to the Host. Current implementation adds new userspace interface ALSA mixer control "Capture Pitch 1000000" (similar to aloop driver's "PCM Rate Shift 100000" mixer control) Value in PPM is chosen to have correction value agnostic of the actual HW rate, which the application is not necessarily dealing with, while still retaining a good enough precision to allow smooth clock correction on the playback side, if necessary. Similar to sound/usb/endpoint.c, a slow down is allowed up to 25%. This has no impact on the required bandwidth. Speedup correction has an impact on the bandwidth reserved for the isochronous endpoint. The default allowed speedup is 500ppm. This seems to be more than enough but, if necessary, this is configurable through a module parameter. The reserved bandwidth is rounded up to the next packet size. Usage of this new control is easy to implement in existing userspace tools like alsaloop from alsa-utils.

2021-06-09usb: gadget: f_uac2: add adaptive sync support for captureRuslan Bilovol2-0/+2
Current f_uac2 USB OUT (aka 'capture') synchronization implements 'ASYNC' scenario which means USB Gadget has it's own freerunning clock and can update Host about real clock frequency through feedback endpoint so Host can align number of samples sent to the USB gadget to prevent overruns/underruns In case if Gadget can has no it's internal clock and can consume audio samples at any rate (for example, on the Gadget side someone records audio directly to a file, or audio samples are played through an external DAC as soon as they arrive), UAC2 spec suggests 'ADAPTIVE' synchronization type. Change UAC2 driver to make it configurable through additional 'c_sync' configfs file. Default remains 'asynchronous' with possibility to switch it to 'adaptive' Signed-off-by: Ruslan Bilovol <ruslan.bilovol@gmail.com> Signed-off-by: Jerome Brunet <jbrunet@baylibre.com> Link: https://lore.kernel.org/r/20210603220104.1216001-3-jbrunet@baylibre.com Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>
