git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip Pull irq driver updates from Thomas Gleixner: - Support for hard indices on RISC-V. The hart index identifies a hart (core) within a specific interrupt domain in RISC-V's Priviledged Architecture. - Rework of the RISC-V MSI driver This moves the driver over to the generic MSI library and solves the affinity problem of unmaskable PCI/MSI controllers. Unmaskable PCI/MSI controllers are prone to lose interrupts when the MSI message is updated to change the affinity because the message write consists of three 32-bit subsequent writes, which update address and data. As these writes are non-atomic versus the device raising an interrupt, the device can observe a half written update and issue an interrupt on the wrong vector. This is mitiated by a carefully orchestrated step by step update and the observation of an eventually pending interrupt on the CPU which issues the update. The algorithm follows the well established method of the X86 MSI driver. - A new driver for the RISC-V Sophgo SG2042 MSI controller - Overhaul of the Renesas RZQ2L driver Simplification of the probe function by using devm_*() mechanisms, which avoid the endless list of error prone gotos in the failure paths. - Expand the Renesas RZV2H driver to support RZ/G3E SoCs - A workaround for Rockchip 3568002 erratum in the GIC-V3 driver to ensure that the addressing is limited to the lower 32-bit of the physical address space. - Add support for the Allwinner AS23 NMI controller - Expand the IMX irqsteer driver to handle up to 960 input interrupts - The usual small updates, cleanups and device tree changes * tag 'irq-drivers-2025-03-23' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip: (40 commits) irqchip/imx-irqsteer: Support up to 960 input interrupts irqchip/sunxi-nmi: Support Allwinner A523 NMI controller dt-bindings: irq: sun7i-nmi: Document the Allwinner A523 NMI controller irqchip/davinci-cp-intc: Remove public header irqchip/renesas-rzv2h: Add RZ/G3E support irqchip/renesas-rzv2h: Update macros ICU_TSSR_TSSEL_{MASK,PREP} irqchip/renesas-rzv2h: Update TSSR_TIEN macro irqchip/renesas-rzv2h: Add field_width to struct rzv2h_hw_info irqchip/renesas-rzv2h: Add max_tssel to struct rzv2h_hw_info irqchip/renesas-rzv2h: Add struct rzv2h_hw_info with t_offs variable irqchip/renesas-rzv2h: Use devm_pm_runtime_enable() irqchip/renesas-rzv2h: Use devm_reset_control_get_exclusive_deasserted() irqchip/renesas-rzv2h: Simplify rzv2h_icu_init() irqchip/renesas-rzv2h: Drop irqchip from struct rzv2h_icu_priv irqchip/renesas-rzv2h: Fix wrong variable usage in rzv2h_tint_set_type() dt-bindings: interrupt-controller: renesas,rzv2h-icu: Document RZ/G3E SoC riscv: sophgo: dts: Add msi controller for SG2042 irqchip: Add the Sophgo SG2042 MSI interrupt controller dt-bindings: interrupt-controller: Add Sophgo SG2042 MSI arm64: dts: rockchip: rk356x: Move PCIe MSI to use GIC ITS instead of MBI ...

2025-03-25rwonce: handle KCSAN like KASAN in read_word_at_a_time()Jann Horn
read_word_at_a_time() is allowed to read out of bounds by straddling the end of an allocation (and the caller is expected to then mask off out-of-bounds data). This works as long as the caller guarantees that the access won't hit a pagefault (either by ensuring that addr is aligned or by explicitly checking where the next page boundary is). Such out-of-bounds data could include things like KASAN redzones, adjacent allocations that are concurrently written to, or simply an adjacent struct field that is concurrently updated. KCSAN should ignore racy reads of OOB data that is not actually used, just like KASAN, so (similar to the code above) change read_word_at_a_time() to use __no_sanitize_or_inline instead of __no_kasan_or_inline, and explicitly inform KCSAN that we're reading the first byte. We do have an instrument_read() helper that calls into both KASAN and KCSAN, but I'm instead open-coding that here to avoid having to pull the entire instrumented.h header into rwonce.h. Also, since this read can be racy by design, we should technically do READ_ONCE(), so add that.

Support TX timestamping in L2CAP sockets. Support MSG_ERRQUEUE recvmsg. For other than SOCK_STREAM L2CAP sockets, if a packet from sendmsg() is fragmented, only the first ACL fragment is timestamped.

2025-03-25Bluetooth: add support for skb TX SND/COMPLETION timestampingPauli Virtanen
Support enabling TX timestamping for some skbs, and track them until packet completion. Generate software SCM_TSTAMP_COMPLETION when getting completion report from hardware. Generate software SCM_TSTAMP_SND before sending to driver. Sending from driver requires changes in the driver API, and drivers mostly are going to send the skb immediately. Make the default situation with no COMPLETION TX timestamping more efficient by only counting packets in the queue when there is nothing to track. When there is something to track, we need to make clones, since the driver may modify sent skbs. The tx_q queue length is bounded by the hdev flow control, which will not send new packets before it has got completion reports for old ones.

2025-03-25net-timestamp: COMPLETION timestamp on packet tx completionPauli Virtanen
Add SOF_TIMESTAMPING_TX_COMPLETION, for requesting a software timestamp when hardware reports a packet completed. Completion tstamp is useful for Bluetooth, as hardware timestamps do not exist in the HCI specification except for ISO packets, and the hardware has a queue where packets may wait. In this case the software SND timestamp only reflects the kernel-side part of the total latency (usually small) and queue length (usually 0 unless HW buffers congested), whereas the completion report time is more informative of the true latency. It may also be useful in other cases where HW TX timestamps cannot be obtained and user wants to estimate an upper bound to when the TX probably happened.

2025-03-25Bluetooth: btnxpuart: Add support to set BD addressNeeraj Sanjay Kale
This adds support for setting BD address during hci registration. NXP FW does not allow vendor commands unless it receives a reset command after FW download and initialization done. As a workaround, the .set_bdaddr callback function will first send the HCI reset command, followed by the actual vendor command to set BD address. The driver checks for the local-bd-address property in device tree, and if preset, it sets the HCI_QUIRK_USE_BDADDR_PROPERTY quirk. With this quirk set, the driver's set_bdaddr callback function is called after FW download is complete and before HCI initialization, which sends the hci reset and 3f 22 commands. During initialization, kernel reads the newly set BD address from the controller.

This also moves the baudrate restore logic from nxp_serdev_remove() to nxp_shutdown() which ensure baudrate is restored even when HCI dev is down, preventing baudrate mismatch between host and controller when device is probed again next time.

2025-03-25Bluetooth: hci_uart: Fix another race during initializationArseniy Krasnov
Do not set 'HCI_UART_PROTO_READY' before call 'hci_uart_register_dev()'. Possible race is when someone calls 'hci_tty_uart_close()' after this bit is set, but 'hci_uart_register_dev()' wasn't done. This leads to access to uninitialized fields. To fix it let's set this bit after device was registered (as before patch c411c62cc133) and to fix previous problem let's add one more bit in addition to 'HCI_UART_PROTO_READY' which allows to perform power up without original bit set (pls see commit c411c62cc133).

2025-03-25Bluetooth: hci_uart: fix race during initializationArseniy Krasnov
'hci_register_dev()' calls power up function, which is executed by kworker - 'hci_power_on()'. This function does access to bluetooth chip using callbacks from 'hci_ldisc.c', for example 'hci_uart_send_frame()'. Now 'hci_uart_send_frame()' checks 'HCI_UART_PROTO_READY' bit set, and if not - it fails. Problem is that 'HCI_UART_PROTO_READY' is set after 'hci_register_dev()', and there is tiny chance that 'hci_power_on()' will be executed before setting this bit. In that case HCI init logic fails. Patch moves setting of 'HCI_UART_PROTO_READY' before calling function 'hci_uart_register_dev()'.
