Hilda Wu authoredBecause mSBC frames do not need to be aligned to the SCO packet boundary. Using USB ALT 3 let HCI payload >= 60 bytes, let mSBC data satisfy 60 Bytes avoid payload unaligned situation and fixed some headset no voise issue. USB Alt 3 supported also need HFP support transparent MTU in 72 Bytes. Signed-off-by:

Even with rate limited reporting this is very spammy and since it is remote device that is providing bogus data there is no need to report this as error. Since real_len variable was used only to allow conditional error message it is now also removed.

This patch adds the 0cf3:e500 Bluetooth device (from a QCA9377 board) as a QCA_ROME device. It appears to be functionally identical to another device ID, also from a QCA9377 board, which was previously marked as QCA_ROME in 0a03f98b ("Bluetooth: Add a new 04ca:3015 QCA_ROME device"). Without this patch, the WiFi side of the QCA9377 board is slow or unusable when the Bluetooth side is in use. See https://askubuntu.com/a/1137852 for another report of QCA_ROME fixing this issue for this device ID. /sys/kernel/debug/usb/devices: T: Bus=05 Lev=01 Prnt=01 Port=00 Cnt=01 Dev#= 2 Spd=12 MxCh= 0 D: Ver= 2.01 Cls=e0(wlcon) Sub=01 Prot=01 MxPS=64 #Cfgs= 1 P: Vendor=0cf3 ProdID=e500 Rev= 0.01 C:* #Ifs= 2 Cfg#= 1 Atr=e0 MxPwr=100mA I:* If#= 0 Alt= 0 #EPs= 3 Cls=e0(wlcon) Sub=01 Prot=01 Driver=btusb E: Ad=81(I) Atr=03(Int.)

During command status or command complete event, the controller may set ncmd=0 indicating that it is not accepting any more commands. In such a case, host holds off sending any more commands to the controller. If the controller doesn't recover from such condition, host will wait forever, until the user decides that the Bluetooth is broken and may power cycles the Bluetooth. This patch triggers the hardware error to reset the controller and driver when it gets into such state as there is no other wat out. Reviewed-by:

When cmtp_attach_device fails, cmtp_add_connection returns the error value which leads to the caller to doing fput through sockfd_put. But cmtp_session kthread, which is stopped in this path will also call fput, leading to a potential refcount underflow or a use-after-free. Add a refcount before we signal the kthread to stop. The kthread will try to grab the cmtp_session_sem mutex before doing the fput, which is held when get_file is called, so there should be no races there. Reported-by: Ryota Shiga Signed-off-by:

The newly implemented fwnode_mdbiobus_register turned out to be problematic - in case the fwnode_/of_/acpi_mdio are built as modules, a dependency cycle can be observed during the depmod phase of modules_install, eg.: depmod: ERROR: Cycle detected: fwnode_mdio -> of_mdio -> fwnode_mdio depmod: ERROR: Found 2 modules in dependency cycles! OR: depmod: ERROR: Cycle detected: acpi_mdio -> fwnode_mdio -> acpi_mdio depmod: ERROR: Found 2 modules in dependency cycles! A possible solution could be to rework fwnode_mdiobus_register, so that to merge the contents of acpi_mdiobus_register and of_mdiobus_register. However feasible, such change would be very intrusive and affect huge amount of the of_mdiobus_register users. Since there are currently 2 users of ACPI and MDIO (xgmac_mdio and mvmdio), withdraw the fwnode_mdbiobus_register and roll back to a simple 'if' condition in affected drivers.

This patch adds build and driver logic for the "mlxbf_gige" Ethernet driver from Mellanox Technologies. The second generation BlueField SoC from Mellanox supports an out-of-band GigaBit Ethernet management port to the Arm subsystem. This driver supports TCP/IP network connectivity for that port, and provides back-end routines to handle basic ethtool requests. The driver interfaces to the Gigabit Ethernet block of BlueField SoC via MMIO accesses to registers, which contain control information or pointers describing transmit and receive resources. There is a single transmit queue, and the port supports transmit ring sizes of 4 to 256 entries. There is a single receive queue, and the port supports receive ring sizes of 32 to 32K entries. The transmit and receive rings are allocated from DMA coherent memory. There is a 16-bit producer and consumer index per ring to denote software ownership and hardware ownership, respectively. The main driver logic such as probe(), remove(), and netdev ops are in "mlxbf_gige_main.c". Logic in "mlxbf_gige_rx.c" and "mlxbf_gige_tx.c" handles the packet processing for receive and transmit respectively. The logic in "mlxbf_gige_ethtool.c" supports the handling of some basic ethtool requests: get driver info, get ring parameters, get registers, and get statistics. The logic in "mlxbf_gige_mdio.c" is the driver controlling the Mellanox BlueField hardware that interacts with a PHY device via MDIO/MDC pins. This driver does the following: - At driver probe time, it configures several BlueField MDIO parameters such as sample rate, full drive, voltage and MDC - It defines functions to read and write MDIO registers and registers the MDIO bus. - It defines the phy interrupt handler reporting a link up/down status change - This driver's probe is invoked from the main driver logic while the phy interrupt handler is registered in ndo_open. Driver limitations - Only supports 1Gbps speed - Only supports GMII protocol - Supports maximum packet size of 2KB - Does not support scatter-gather buffering Testing - Successful build of kernel for ARM64, ARM32, X86_64 - Tested ARM64 build on FastModels & Palladium - Tested ARM64 build on several Mellanox boards that are built with the BlueField-2 SoC. The testing includes coverage in the areas of networking (e.g. ping, iperf, ifconfig, route), file transfers (e.g. SCP), and various ethtool options relevant to this driver.

This patch is modeled after one by Scott Peterson for i40e. Add tracepoints to the driver, via a new file ice_trace.h and some new trace calls added in interesting places in the driver. Add some tracing for DIMLIB to help debug interrupt moderation problems. Performance should not be affected, and this can be very useful for debugging and adding new trace events to paths in the future. Note eBPF programs can attach to these events, as well as perf can count them since we're attaching to the events subsystem in the kernel. Co-developed-by:

The Broadcom UniMAC MDIO bus from mdio-bcm-unimac module comes too late. So, GENET cannot find the ethernet PHY on UniMAC MDIO bus. This leads GENET fail to attach the PHY as following log: bcmgenet fd580000.ethernet: GENET 5.0 EPHY: 0x0000 ... could not attach to PHY bcmgenet fd580000.ethernet eth0: failed to connect to PHY uart-pl011 fe201000.serial: no DMA platform data libphy: bcmgenet MII bus: probed ... unimac-mdio unimac-mdio.-19: Broadcom UniMAC MDIO bus It is not just coming too late, there is also no way for the module loader to figure out the dependency between GENET and its MDIO bus driver unless we provide this MODULE_SOFTDEP hint. This patch adds the soft dependency to load mdio-bcm-unimac module before genet module to fix this issue.
