2022-07-20can: error: add definitions for the different CAN error thresholdsVincent Mailhol
Currently, drivers are using magic numbers to derive the CAN error states from the error counter. Add three macro declarations to remediate this. For reference, the error-active, error-passive and bus-off are defined in ISO 11898, section 12.1.4.2 "Error counting". Although ISO 11898 does not define error-warning state, this extra value is also commonly used and is thus also added.

2022-07-20can: error: specify the values of data[5..7] of CAN error framesVincent Mailhol
Currently, data[5..7] of struct can_frame, when used as a CAN error frame, are defined as being "controller specific". Device specific behaviours are problematic because it prevents someone from writing code which is portable between devices. As a matter of fact, data[5] is never used, data[6] is always used to report TX error counter and data[7] is always used to report RX error counter. can-utils also relies on this. This patch updates the comment in the uapi header to specify that data[5] is reserved (and thus should not be used) and that data[6..7] are used for error counters.

2022-07-19PCI/DOE: Add DOE mailbox support functionsJonathan Cameron
Introduced in a PCIe r6.0, sec 6.30, DOE provides a config space based mailbox with standard protocol discovery. Each mailbox is accessed through a DOE Extended Capability. Each DOE mailbox must support the DOE discovery protocol in addition to any number of additional protocols. Define core PCIe functionality to manage a single PCIe DOE mailbox at a defined config space offset. Functionality includes iterating, creating, query of supported protocol, and task submission. Destruction of the mailboxes is device managed.

2022-07-19RDMA/mlx5: Expose steering anchor to userspaceMark Bloch
Expose a steering anchor per priority to allow users to re-inject packets back into default NIC pipeline for additional processing. MLX5_IB_METHOD_STEERING_ANCHOR_CREATE returns a flow table ID which a user can use to re-inject packets at a specific priority. A FTE (flow table entry) can be created and the flow table ID used as a destination. When a packet is taken into a RDMA-controlled steering domain (like software steering) there may be a need to insert the packet back into the default NIC pipeline. This exposes a flow table ID to the user that can be used as a destination in a flow table entry. With this new method priorities that are exposed to users via MLX5_IB_METHOD_FLOW_MATCHER_CREATE can be reached from a non-zero UID. As user-created flow tables (via RDMA DEVX) are created with a non-zero UID thus it's impossible to point to a NIC core flow table (core driver flow tables are created with UID value of zero) from userspace. Create flow tables that are exposed to users with the shared UID, this allows users to point to default NIC flow tables. Steering loops are prevented at FW level as FW enforces that no flow table at level X can point to a table at level lower than X.

Add a new flag that indicates that this control is a dynamically sized array. Also document this flag. Currently dynamically sized arrays are limited to one dimensional arrays, but that might change in the future if there is a need for it. The initial use-case of dynamic arrays are stateless codecs. A frame can be divided in many slices, so you want to provide an array containing slice information for each slice. Typically the number of slices is small, but the standard allow for hundreds or thousands of slices. Dynamic arrays are a good solution since sizing the array for the worst case would waste substantial amounts of memory.

The SOF and Intel DSP code both also continue to be very actively developed. - Restructing of the set_fmt() callbacks to be specified in terms of the device rather than with semantics depending on if the device is supposed to be a CODEC or SoC, making things clearer in situations like CODEC to CODEC links. - Clean up of the way we flag which DAI naming scheme we use to reflect the progress that's been made modernising things. - Merge of more of the Intel AVS driver stack, including some board integrations. - New version 4 mechanism for communication with SOF DSPs. - Suppoort for dynamically selecting the PLL to use at runtime on i.MX platforms. - Improvements for CODEC to CODEC support in the generic cards. - Support for AMD Jadeite and various machines, Intel MetorLake DSPs, Mediatek MT8186 DSPs and MT6366, nVidia Tegra MDDRC, OPE and PEQ, NXP TFA9890, Qualcomm SDM845, WCD9335 and WAS883x, and Texas Instruments TAS2780.

2022-07-14ublk_drv: support to complete io command via task_work_addMing Lei
Use task_work_add if it is available, since task_work_add can bring up better performance, especially batching signaling ->ubq_daemon can be done. It is observed that task_work_add() can boost iops by +4% on random 4k io test. Also except for completing io command, all other code paths are same with completing io command via io_uring_cmd_complete_in_task. Meantime add one flag of UBLK_F_URING_CMD_COMP_IN_TASK for comparing the mode easily.

2022-07-14ublk_drv: add io_uring based userspace block driverMing Lei
This is the driver part of userspace block driver(ublk driver), the other part is userspace daemon part(ublksrv)[1]. The two parts communicate by io_uring's IORING_OP_URING_CMD with one shared cmd buffer for storing io command, and the buffer is read only for ublksrv, each io command is indexed by io request tag directly, and is written by ublk driver. For example, when one READ io request is submitted to ublk block driver, ublk driver stores the io command into cmd buffer first, then completes one IORING_OP_URING_CMD for notifying ublksrv, and the URING_CMD is issued to ublk driver beforehand by ublksrv for getting notification of any new io request, and each URING_CMD is associated with one io request by tag. After ublksrv gets the io command, it translates and handles the ublk io request, such as, for the ublk-loop target, ublksrv translates the request into same request on another file or disk, like the kernel loop block driver. In ublksrv's implementation, the io is still handled by io_uring, and share same ring with IORING_OP_URING_CMD command. When the target io request is done, the same IORING_OP_URING_CMD is issued to ublk driver for both committing io request result and getting future notification of new io request. Another thing done by ublk driver is to copy data between kernel io request and ublksrv's io buffer: 1) before ubsrv handles WRITE request, copy the request's data into ublksrv's userspace io buffer, so that ublksrv can handle the write request 2) after ubsrv handles READ request, copy ublksrv's userspace io buffer into this READ request, then ublk driver can complete the READ request Zero copy may be switched if mm is ready to support it. ublk driver doesn't handle any logic of the specific user space driver, so it is small/simple enough.

2022-07-14kvm: stats: tell userspace which values are booleanPaolo Bonzini
Some of the statistics values exported by KVM are always only 0 or 1. It can be useful to export this fact to userspace so that it can track them specially (for example by polling the value every now and then to compute a % of time spent in a specific state). Therefore, add "boolean value" as a new "unit". While it is not exactly a unit, it walks and quacks like one. In particular, using the type would be wrong because boolean values could be instantaneous or peak values (e.g. "is the rmap allocated?") or even two-bucket histograms (e.g. "number of posted vs. non-posted interrupt injections").
