2022-03-18regmap: allow a defined reg_base to be added to every addressColin Foster
There's an inconsistency that arises when a register set can be accessed internally via MMIO, or externally via SPI. The VSC7514 chip allows both modes of operation. When internally accessed, the system utilizes __iomem, devm_ioremap_resource, and devm_regmap_init_mmio. For SPI it isn't possible to utilize memory-mapped IO. To properly operate, the resource base must be added to the register before every operation.

2022-03-18regmap: add configurable downshift for addressesColin Foster
Add an additional reg_downshift to be applied to register addresses before any register accesses.

The DSDT for the Asus TF103C specifies a IOAPIC IRQ for the HCI -> host IRQ but this is not correct. Unlike the previous entries in the table, this time the correct GPIO to use instead is known; and the TF103C is battery powered making runtime-pm support more important. Extend the bcm_broken_irq_dmi_table mechanism to allow specifying the right GPIO instead of just always disabling runtime-pm and add an entry to it for the Asus TF103C.

2022-03-18Bluetooth: btmtksdio: Fix kernel oops in btmtksdio_interruptYake Yang
Fix the following kernel oops in btmtksdio_interrrupt [ 14.339134] btmtksdio_interrupt+0x28/0x54 [ 14.339139] process_sdio_pending_irqs+0x68/0x1a0 [ 14.339144] sdio_irq_work+0x40/0x70 [ 14.339154] process_one_work+0x184/0x39c [ 14.339160] worker_thread+0x228/0x3e8 [ 14.339168] kthread+0x148/0x3ac [ 14.339176] ret_from_fork+0x10/0x30 That happened because hdev->power_on is already called before sdio_set_drvdata which btmtksdio_interrupt handler relies on is not properly set up. The details are shown as the below: hci_register_dev would run queue_work(hdev->req_workqueue, &hdev->power_on) as WQ_HIGHPRI workqueue_struct to complete the power-on sequeunce and thus hci_power_on may run before sdio_set_drvdata is done in btmtksdio_probe. The hci_dev_do_open in hci_power_on would initialize the device and enable the interrupt and thus it is possible that btmtksdio_interrupt is being called right before sdio_set_drvdata is filled out. When btmtksdio_interrupt is being called and sdio_set_drvdata is not filled , the kernel oops is going to happen because btmtksdio_interrupt access an uninitialized pointer.

2022-03-18Bluetooth: btusb: Use quirk to skip HCI_FLT_CLEAR_ALL on fake CSR controllersIsmael Ferreras Morezuelas
Another subset of the more recent batch of Chinese clones aren't specs-compliant and seem to lock up whenever they receive a HCI_OP_SET_EVENT_FLT with flt_type set to zero/HCI_FLT_CLEAR_ALL, which on Linux (until the recent HCI state-machine refactor) happened right at BR/EDR setup. As there are other less-straightforward ways of reaching those operations, this patch is still relevant. So, while all the previous efforts to wrangle the herd of fake CSRs seem to be paying off (and these also get detected as such) we still need to take care of this quirk; testers seem to agree that these dongles tend to work well enough afterwards. From some cursory USB packet capture on Windows it seems like that driver doesn't appear to use this clear-all functionality at all. This patch was tested on some really popular AliExpress-style dongles, in my case marked as "V5.0". Chip markings: UG8413, the backside of the PCB says "USB Dangel" (sic).

2022-03-18Bluetooth: btmtkuart: fix the conflict between mtk and msft vendor eventSean Wang
There is a conflict between MediaTek wmt event and msft vendor extension logic in the core layer since 145373cb1b1f ("Bluetooth: Add framework for Microsoft vendor extension") was introduced because we changed the type of mediatek wmt event to the type of msft vendor event in the driver. But the purpose we reported mediatek event to the core layer is for the diagnostic purpose with that we are able to see the full packet trace via monitoring socket with btmon. Thus, it is harmless we keep the original type of mediatek vendor event here to avoid breaking the msft extension function especially they can be supported by Mediatek future devices.

2022-03-18clocksource: acpi_pm: fix return value of __setup handlerRandy Dunlap
__setup() handlers should return 1 to obsolete_checksetup() in init/main.c to indicate that the boot option has been handled. A return of 0 causes the boot option/value to be listed as an Unknown kernel parameter and added to init's (limited) environment strings. The __setup() handler interface isn't meant to handle negative return values -- they are non-zero, so they mean "handled" (like a return value of 1 does), but that's just a quirk. So return 1 from parse_pmtmr(). Also print a warning message if kstrtouint() returns an error.

However just after the queue was stopped, an in-flight ibmvnic_complete_tx() could have restarted the queue even as the reset is progressing. Since the queue was restarted we could get a call to ibmvnic_xmit() which can then access the bad tx_scrq (or other fields). We cannot however simply have ibmvnic_complete_tx() check the ->resetting bit and skip starting the queue. This can race at the "back-end" of a good reset which just restarted the queue but has not cleared the ->resetting bit yet. If we skip restarting the queue due to ->resetting being true, the queue would remain stopped indefinitely potentially leading to transmit timeouts. IOW ->resetting is too broad for this purpose. Instead use a new flag that indicates whether or not the queues are active. Only the open/ reset paths control when the queues are active. ibmvnic_complete_tx() and others wake up the queue only if the queue is marked active. So we will have: A. reset/open thread in ibmvnic_cleanup() and __ibmvnic_open() ->resetting = true ->tx_queues_active = false disable tx queues ... ->tx_queues_active = true start tx queues B. Tx interrupt in ibmvnic_complete_tx(): if (->tx_queues_active) netif_wake_subqueue(); To ensure that ->tx_queues_active and state of the queues are consistent, we need a lock which: - must also be taken in the interrupt path (ibmvnic_complete_tx()) - shared across the multiple queues in the adapter (so they don't become serialized) Use rcu_read_lock() and have the reset thread synchronize_rcu() after updating the ->tx_queues_active state. While here, consolidate a few boolean fields in ibmvnic_adapter for better alignment. Based on discussions with Brian King and Dany Madden.

Non-linear legacy RQ: validate MTU for robustness, build the linear part of SKB over the first hardware fragment (instead of copying the packet headers), adjust headroom calculations to allow enabling headroom in the non-linear mode (useful for XDP multi buffer). b. XDP: do the XDP program test before function call, optimize parameters of mlx5e_xdp_handle. 2) From Rongwei Liu, DR, reduce steering memory usage Currently, mlx5 driver uses mlx5_htbl/chunk/ste to organize steering logic. However there is a little memory waste. This update targets to reduce steering memory footprint by: a. Adjust struct member layout. b. Remove duplicated indicator by using simple functions call. With 500k TX rules(3 ste) plus 500k RX rules(6 stes), these patches can save around 17% memory. 3) Three cleanup commits at the end of this series. =================== Signed-off-by: David S.

If there is an input undervoltage fault, reported in STATUS_INPUT command response, there is quite likely a "Unit Off For Insufficient Input Voltage" condition as well. Add a constant for bit 3 of STATUS_INPUT. Update the Vin limit attributes to include both bits in the mask for clearing faults. If an input undervoltage fault occurs, causing a unit off for insufficient input voltage, but the unit is off bit is not cleared, the STATUS_WORD will not be updated to clear the input fault condition.
