* Bluetooth: hci_qca: Add support for QTI Bluetooth chip wcn6855Steev Klimaszewski2023-04-243-15/+66
| | | | | | | | | | | | | | | Add regulators, GPIOs and changes required to power on/off wcn6855. Add support for firmware download for wcn6855 which is in the linux-firmware repository as hpbtfw21.tlv and hpnv21.bin.

* Bluetooth: btrtl: check for NULL in btrtl_set_quirks()Max Chou2023-04-241-0/+3
| | | | | | | | | | | The btrtl_set_quirks() has accessed btrtl_dev->ic_info->lmp_subver since b8e482d02513. However, if installing a Realtek Bluetooth controller without the driver supported, it will hit the NULL point accessed. Add a check for NULL to avoid the Kernel Oops.

* Bluetooth: NXP: Add protocol support for NXP Bluetooth chipsetsNeeraj Sanjay Kale2023-04-243-0/+1310
| | | | | | | | | | | | | | | | | | | | | This adds a driver based on serdev driver for the NXP BT serial protocol based on running H:4, which can enable the built-in Bluetooth device inside an NXP BT chip. This driver has Power Save feature that will put the chip into sleep state whenever there is no activity for 2000ms, and will be woken up when any activity is to be initiated over UART. This driver enables the power save feature by default by sending the vendor specific commands to the chip during setup. During setup, the driver checks if a FW is already running on the chip by waiting for the bootloader signature, and downloads device specific FW file into the chip over UART if bootloader signature is received..

| | | | | | | | | | | | | | | | The Realtek RTL8723CS is a SDIO WiFi chip. It also contains a Bluetooth module which is connected via UART to the host. It shares lmp subversion with 8703B, so Realtek's userspace initialization tool (rtk_hciattach) differentiates varieties of RTL8723CS (CG, VF, XX) with RTL8703B using vendor's command to read chip type. Also this chip declares support for some features it doesn't support so add a quirk to indicate that these features are broken.

| * ice: sleep, don't busy-wait, for ICE_CTL_Q_SQ_CMD_TIMEOUTMichal Schmidt2023-04-213-12/+13
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The driver polls for ice_sq_done() with a 100 µs period for up to 1 s and it uses udelay to do that. Let's use usleep_range instead. We know sleeping is allowed here, because we're holding a mutex (cq->sq_lock). To preserve the total max waiting time, measure the timeout in jiffies. ICE_CTL_Q_SQ_CMD_TIMEOUT is used also in ice_release_res(), but there the polling period is 1 ms (i.e. 10 times longer). Since the timeout was expressed in terms of the number of loops, the total timeout in this function is 10 s. I do not know if this is intentional. This patch keeps it. The patch lowers the CPU usage of the ice-gnss-<dev_name> kernel thread on my system from ~8 % to less than 1 %. I received a report of high CPU usage with ptp4l where the busy-waiting in ice_sq_send_cmd dominated the profile. This patch has been tested in that usecase too and it made a huge improvement there.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The ice-gnss-<dev_name> kernel thread, which reads data from the u-blox GNSS module, keep a CPU core almost 100% busy. The main reason is that it busy-waits for data to become available. A simple improvement would be to replace the "mdelay(10);" in ice_gnss_read() with sleeping. A better fix is to not do any waiting directly in the function and just requeue this delayed work as needed. The advantage is that canceling the work from ice_gnss_exit() becomes immediate, rather than taking up to ~2.5 seconds (ICE_MAX_UBX_READ_TRIES * 10 ms). This lowers the CPU usage of the ice-gnss-<dev_name> thread on my system from ~90 % to ~8 %. I am not sure if the larger 0.1 s pause after inserting data into the gnss subsystem is really necessary, but I'm keeping that as it was. Of course, ideally the driver would not have to poll at all, but I don't know if the E810 can watch for GNSS data availability over the i2c bus by itself and notify the driver.

In other words, the counters are not exposed for representor interfaces. Furthermore, the debugfs design is inconvenient future-wise, in case more counters need to be reported by the driver in the future. As these counters pertain to vNIC health, it is more appropriate to utilize the devlink health reporter to expose them. Thus, this patchest includes the following changes: * Drop the current vnic diagnostic counters debugfs interface. * Add a vnic devlink health reporter for PFs/VFs core devices, which when diagnosed will dump vnic diagnostic counter values that are queried from FW. * Add a vnic devlink health reporter for the representor interface, which serves the same purpose listed in the previous point, in addition to allowing the hypervisor to view its VFs diagnostic counters, even when the VFs are bounded to external VMs. Example of devlink health reporter usage is: $devlink health diagnose pci/0000:08:00.0 reporter vnic vNIC env counters: total_error_queues: 0 send_queue_priority_update_flow: 0 comp_eq_overrun: 0 async_eq_overrun: 0 cq_overrun: 0 invalid_command: 0 quota_exceeded_command: 0 nic_receive_steering_discard: 0 =========== 4) SW steering fixes and improvements Yevgeny Kliteynik Says: ======================= These short patch series are just small fixes / improvements for SW steering: - Patch 1: Fix dumping of legacy modify_hdr in debug dump to align to what is expected by parser - Patch 2: Have separate threshold for ICM sync per ICM type - Patch 3: Add more info to the steering debug dump - Linux version and device name - Patch 4: Keep track of number of buddies that are currently in use per domain per buddy type ======================= * tag 'mlx5-updates-2023-04-20' of git://git.kernel.org/pub/scm/linux/kernel/git/saeed/linux: net/mlx5: Update op_mode to op_mod for port selection net/mlx5: E-Switch, Remove unused mlx5_esw_offloads_vport_metadata_set() net/mlx5: E-Switch, Remove redundant dev arg from mlx5_esw_vport_alloc() net/mlx5: Include linux/pci.h for pci_msix_can_alloc_dyn() net/mlx5e: RX, Hook NAPIs to page pools net/mlx5e: RX, Fix XDP_TX page release for legacy rq nonlinear case net/mlx5e: RX, Fix releasing page_pool pages twice for striding RQ net/mlx5e: Add vnic devlink health reporter to representors net/mlx5: Add vnic devlink health reporter to PFs/VFs Revert "net/mlx5: Expose vnic diagnostic counters for eswitch managed vports" Revert "net/mlx5: Expose steering dropped packets counter" net/mlx5: DR, Add memory statistics for domain object net/mlx5: DR, Add more info in domain dbg dump net/mlx5: DR, Calculate sync threshold of each pool according to its type net/mlx5: DR, Fix dumping of legacy modify_hdr in debug dump ==================== Link: https://lore.kernel.org/r/20230421013850.349646-1-saeed@kernel.org Signed-off-by: Jakub Kicinski <kuba@kernel.org>

Fully freeing ICM memory involves issuing FW SYNC_STEERING command. This is very time consuming, and it is impractical to do it for every freed chunk. Instead, we manage these 'freed' chunks in hot list (list of chunks that are not required by SW any more, but HW might still access them). When size of the hot list reaches certain threshold, we purge it and issue SYNC_STEERING FW command. There is one threshold for all the different ICM types, which is not optimal, as different ICM types require different approach: STEs pool is very large, and it is very 'dynamic' in its nature, so letting hot list to become too large will result in a significant perf hiccup when purging the hot list. Modify action is much smaller and less dynamic, so we can let the hot list to grow to almost the size of the whole pool. This patch fixes this problem: instead of having same hot memory threshold for all the pools, sync operation will be triggered in accordance with the ICM type.
