Firmware download to the WCN3990 often fails with a 'TLV response size mismatch' error: [ 133.064659] Bluetooth: hci0: setting up wcn3990 [ 133.489150] Bluetooth: hci0: QCA controller version 0x02140201 [ 133.495245] Bluetooth: hci0: QCA Downloading qca/crbtfw21.tlv [ 133.507214] Bluetooth: hci0: QCA TLV response size mismatch [ 133.513265] Bluetooth: hci0: QCA Failed to download patch (-84) This is caused by a vendor event that corresponds to an earlier command to change the baudrate. The event is not processed in the context of the baudrate change and is later interpreted as response to the firmware download command (which is also a vendor command), but the driver detects that the event doesn't have the expected amount of associated data. More details: For the WCN3990 the vendor command for a baudrate change isn't sent as synchronous HCI command, because the controller sends the corresponding vendor event with the new baudrate. The event is received and decoded after the baudrate change of the host port. Identify the 'unused' event when it is received and don't add it to the queue of RX frames. Signed-off-by:

Latest qualcomm chips are not sending an command complete event for every firmware packet sent to chip. They only respond with a vendor specific event for the last firmware packet. This optimization will decrease the BT ON time. Due to this we are seeing a timeout error message logs on the console during firmware download. Now we are injecting a command complete event once we receive an vendor specific event for the last RAM firmware packet. Signed-off-by:

Realtek RTL8822BE BT chip on ASUS X420FA cannot be turned on correctly after on-off several times. Bluetooth daemon sets BT mode failed when this issue happens. Scanning must be active while turning off for this bug to be hit. bluetoothd[1576]: Failed to set mode: Failed (0x03) If BT is turned off, then turned on again, it works correctly again. According to the vendor driver, the HCI_QUIRK_RESET_ON_CLOSE flag is set during probing. So, this patch makes Realtek's BT reset on close to fix this issue.

Tariq Toukan says: ==================== mlx5 TLS TX HW offload support This series from Eran and me, adds TLS TX HW offload support to the mlx5 driver. This offloads the kTLS encryption process from kernel to the Mellanox NIC, saving CPU cycles and improving utilization. Upon a new TLS connection request, driver is responsible to create a dedicated HW context and configure it according to the crypto info, so HW can do the encryption itself. When the HW context gets out-of-sync (i.e. due to packets retransmission), driver is responsible for the re-sync process. This is done by posting special resync descriptors to the HW. Feature is supported on Mellanox Connect-X 6DX, and newer. Series was tested on SimX simulator. Series generated against net-next commit [1], with Saeed's request pulled [2]: [1] c4cde580 Merge git://git.kernel.org/pub/scm/linux/kernel/git/bpf/bpf-next [2] git://git.kernel.org/pub/scm/linux/kernel/git/saeed/linux.git tags/mlx5-updates-2019-07-04-v2 Changes from last pull request: Fixed comments from Jakub: Patch 4: - Replace zero memset with a call to memzero_explicit(). Patch 11: - Fix stats counters names. - Drop TLS SKB with non-matching netdev. ==================== Acked-by:

Add support for transmit side kernel-TLS acceleration. Offload the crypto encryption to HW. Per TLS connection: - Use a separate TIS to maintain the HW context. - Use a separate encryption key. - Maintain static and progress HW contexts by posting the proper WQEs at creation time, or upon resync. - Use a special DUMP opcode to replay the previous frags and sync the HW context. To make sure the SQ is able to serve an xmit request, increase SQ stop room to cover: - static params WQE, - progress params WQE, and - resync DUMP per frag. Currently supporting TLS 1.2, and key size 128bit. Tested over SimX simulator. Signed-off-by:

Change mlx5e_sq_fetch_wqe to be agnostic to the Work Queue Element (WQE) type. Before this patch, it was specific for struct mlx5e_tx_wqe. In order to allow the change, the function now returns the generic void pointer, and gets the WQE size to do the zero memset. Signed-off-by:

Always contain all acceleration functions declarations in 'accel' files, independent to the flags setting. For this, introduce new flags CONFIG_FPGA_{IPSEC/TLS} and use stubs where needed.

Quoting Arnd, We have to do a sync_single_for_device /somewhere/ before the buffer is given to the device. On a non-cache-coherent machine with a write-back cache, there may be dirty cache lines that get written back after the device DMA's data into it (e.g. from a previous memset from before the buffer got freed), so you absolutely need to flush any dirty cache lines on it first. Since the coherency is configurable in this device make sure we cover all configurations by explicitly syncing the allocated buffer for the device before refilling it's descriptors Signed-off-by:

Ido Schimmel says: ==================== mlxsw: Enable/disable PTP shapers Shalom says: In order to get more accurate hardware time stamping in Spectrum-1, the driver needs to apply a shaper on the port for speeds lower than 40Gbps. This shaper is called a PTP shaper and it is applied on hierarchy 0, which is the port hierarchy. This shaper may affect the shaper rates of all hierarchies. This patchset adds the ability to enable or disable the PTP shaper on the port in two scenarios: 1. When the user wants to enable/disable the hardware time stamping 2. When the port is brought up or down (including port speed change) Patch #1 adds the QEEC.ptps field that is used for enabling or disabling the PTP shaper on a port. Patch #2 adds a note about disabling the PTP shaper when calling to mlxsw_sp_port_ets_maxrate_set(). Patch #3 adds the QPSC register that is responsible for configuring the PTP shaper parameters per speed. Patch #4 sets the PTP shaper parameters during the ptp_init(). Patch #5 adds new operation for getting the port's speed. Patch #6 enables/disables the PTP shaper when turning on or off the hardware time stamping. Patch #7 enables/disables the PTP shaper when the port's status has changed (including port speed change). Patch #8 applies the PTP shaper enable/disable logic by filling the PTP shaper parameters array. ==================== Signed-off-by: -
