2025-10-29Documentation: intel_pstate: fix duplicate hyperlink target errorsSwaraj Gaikwad
Fix reST warnings in Documentation/admin-guide/pm/intel_pstate.rst caused by missing explicit hyperlink labels for section titles. Before this change, the following errors were printed during `make htmldocs`: Documentation/admin-guide/pm/intel_pstate.rst:401: ERROR: Indirect hyperlink target (id="id6") refers to target "passive mode", which is a duplicate, and cannot be used as a unique reference. Documentation/admin-guide/pm/intel_pstate.rst:517: ERROR: Indirect hyperlink target (id="id9") refers to target "active mode", which is a duplicate, and cannot be used as a unique reference. Documentation/admin-guide/pm/intel_pstate.rst:611: ERROR: Indirect hyperlink target (id="id15") refers to target "global attributes", which is a duplicate, and cannot be used as a unique reference. ERROR: Duplicate target name, cannot be used as a unique reference: "passive mode", "active mode", "global attributes". These errors occurred because the sections "Active Mode", "Active Mode With HWP", "Passive Mode", and "Global Attributes" did not define explicit hyperlink labels. As a result, Sphinx auto-generated duplicate anchors when the same titles appeared multiple times within the document. Because of this, the generated HTML documentation contained broken references such as: `active mode <Active Mode_>`_ `passive mode <Passive Mode_>`_ `global attributes <Global Attributes_>`_ This patch adds explicit hyperlink labels for the affected sections, ensuring all references are unique and correctly resolved. After applying this patch, `make htmldocs` completes without any warnings, and all hyperlinks in intel_pstate.html render properly.

2025-10-28tracing: Add a config and syscall_user_buf_size file to limit amount writtenSteven Rostedt
When a system call that can copy user space addresses into the ring buffer, it can copy up to 511 bytes of data. This can waste precious ring buffer space if the user isn't interested in the output. Add a new file "syscall_user_buf_size" that gets initialized to a new config CONFIG_SYSCALL_BUF_SIZE_DEFAULT that defaults to 63. The config also is used to limit how much perf can read from user space. Also lower the max down to 165, as this isn't to record everything that a system call may be passing through to the kernel. 165 is more than enough. The reason for 165 is because adding one for the nul terminating byte, as well as possibly needing to append the "..." string turns it into 170 bytes. As this needs to save up to 3 arguments and 3 * 170 is 510 which fits nicely in 512 bytes (a power of 2).

2025-10-28net: stmmac: Add a devlink attribute to control timestamping modeMaxime Chevallier
The DWMAC1000 supports 2 timestamping configurations to configure how frequency adjustments are made to the ptp_clock, as well as the reported timestamp values. There was a previous attempt at upstreaming support for configuring this mode by Olivier Dautricourt and Julien Beraud a few years back [1] In a nutshell, the timestamping can be either set in fine mode or in coarse mode. In fine mode, which is the default, we use the overflow of an accumulator to trigger frequency adjustments, but by doing so we lose precision on the timetamps that are produced by the timestamping unit. The main drawback is that the sub-second increment value, used to generate timestamps, can't be set to lower than (2 / ptp_clock_freq). The "fine" qualification comes from the frequent frequency adjustments we are able to do, which is perfect for a PTP follower usecase. In Coarse mode, we don't do frequency adjustments based on an accumulator overflow. We can therefore have very fine subsecond increment values, allowing for better timestamping precision. However this mode works best when the ptp clock frequency is adjusted based on an external signal, such as a PPS input produced by a GPS clock. This mode is therefore perfect for a Grand-master usecase. Introduce a driver-specific devlink parameter "ts_coarse" to enable or disable coarse mode, keeping the "fine" mode as a default. This can then be changed with: devlink dev param set <dev> name ts_coarse value true cmode runtime The associated documentation is also added.

2025-10-28ALSA: cs35l56: Add support for factory calibrationMark Brown
Merge series from Richard Fitzgerald <rf@opensource.cirrus.com>: Until now, all products with an amplifier supported by the cs35l56 driver have shipped with Microsoft Windows pre-installed. The factory calibration of speaker protection has therefore been done using the Windows driver. However, products that ship with a Linux-based distro must be able to perform the factory calibration procedure from within the Linux-based environment. This patch series adds that support. NOTE: unfortunately this is yet another series that is mainly ASoC but also needs some changes to the HDA driver, and they have build dependencies on the ASoC code. I suggest taking this all through Mark's tree and we'll avoid sending any other commits to the HDA driver until it has all landed in Takashi's tree.

Commit 267bca002c50 ("dt-bindings: net: sparx5: correct LAN969x register space windows") said that LAN969x has exactly two address spaces ("reg" property) but implemented it as 2 or more. Narrow the constraint to properly express that only two items are allowed, which also matches Linux driver.

2025-10-27dpll: spec: add missing module-name and clock-id to pin-get replyPetr Oros
The dpll.yaml spec incorrectly omitted module-name and clock-id from the pin-get operation reply specification, even though the kernel DPLL implementation has always included these attributes in pin-get responses since the initial implementation. This spec inconsistency caused issues with the C YNL code generator. The generated dpll_pin_get_rsp structure was missing these fields. Fix the spec by adding module-name and clock-id to the pin-attrs reply specification to match the actual kernel behavior.

2025-10-27net/tls: support setting the maximum payload sizeWilfred Mallawa
During a handshake, an endpoint may specify a maximum record size limit. Currently, the kernel defaults to TLS_MAX_PAYLOAD_SIZE (16KB) for the maximum record size. Meaning that, the outgoing records from the kernel can exceed a lower size negotiated during the handshake. In such a case, the TLS endpoint must send a fatal "record_overflow" alert [1], and thus the record is discarded. Upcoming Western Digital NVMe-TCP hardware controllers implement TLS support. For these devices, supporting TLS record size negotiation is necessary because the maximum TLS record size supported by the controller is less than the default 16KB currently used by the kernel. Currently, there is no way to inform the kernel of such a limit. This patch adds support to a new setsockopt() option `TLS_TX_MAX_PAYLOAD_LEN` that allows for setting the maximum plaintext fragment size. Once set, outgoing records are no larger than the size specified. This option can be used to specify the record size limit.

2025-10-27ASoC: dt-bindings: allwinner,sun4i-a10-spdif: Add compatible for A523Chen-Yu Tsai
The SPDIF hardware block in the A523 SoC has the same layout as the H616 for the transmitter side. However unlike previous generations, the hardware block now takes separate module clocks for the TX and RX sides. This presumably allows the hardware to send and receive audio streams at different sample rates. The new hardware also gained RX insertion detection, and some extra information registers. Add a new compatible for it without any fallbacks.
