2025-08-14dt-bindings: serial: 8250: allow "main" and "uart" as clock namesAlex Elder1-1/+9
There are two compatible strings defined in "8250.yaml" that require two clocks to be specified, along with their names: - "spacemit,k1-uart", used in "spacemit/k1.dtsi" - "nxp,lpc1850-uart", used in "lpc/lpc18xx.dtsi" When only one clock is used, the name is not required. However there are two places that do specify a name: - In "mediatek/mt7623.dtsi", the clock for the "mediatek,mtk-btif" compatible serial device is named "main" - In "qca/ar9132.dtsi", the clock for the "ns8250" compatible serial device is named "uart" In commit d2db0d7815444 ("dt-bindings: serial: 8250: allow clock 'uartclk' and 'reg' for nxp,lpc1850-uart"), Frank Li added the restriction that two named clocks be used for the NXP platform mentioned above. Change that logic, so that an additional condition for (only) the SpacemiT platform similarly restricts the two clocks to have the names "core" and "bus". Finally, add "main" and "uart" as allowed names when a single clock is specified.

2025-08-14net: ethtool: support including Flow Label in the flow hash for RSSJakub Kicinski1-0/+3
Some modern NICs support including the IPv6 Flow Label in the flow hash for RSS queue selection. This is outside the old "Microsoft spec", but was included in the OCP NIC spec: [ ] RSS include flow label in the hash (configurable) https://www.opencompute.org/w/index.php?title=Core_Offloads#Receive_Side_Scaling RSS Flow Label hashing allows TCP Protective Load Balancing (PLB) to recover from receiver congestion / overload. Rx CPU/queue hotspots are relatively common for data ingest workloads, and so far we had to try to detect the condition at the RPC layer and reopen the connection. PLB lets us change the Flow Label and therefore Rx CPU on RTO, with minimal packet reordering. PLB reaction times are much faster, and can happen at any point in the connection, not just at RPC boundaries. Due to the nature of host processing (relatively long queues, other kernel subsystems masking IRQs for 100s of msecs) the risk of reordering within the host is higher than in the network. But for applications which need it - it is far preferable to potentially persistent overload of subset of queues. It is expected that the hash communicated to the host may change if the Flow Label changes. This may be surprising to some host software, but I don't expect the devices can compute two Toeplitz hashes, one with the Flow Label for queue selection and one without for the rx hash communicated to the host. Besides, changing the hash may potentially help to change the path thru host queues. User can disable NETIF_F_RXHASH if they require a stable flow hash. The name RXH_IP6_FL was chosen based on what we call Flow Label variables in IPv6 processing (fl). I prefer fl_lbl but that appears to be an fbnic-only spelling. We could spell out RXH_IP6_FLOW_LABEL but existing RXH_ defines are a lot more terse. Willem notes [1] that Flow Label is defined as identifying the flow and therefore including both the flow label _and_ the L4 header fields is not generally necessary. But it should not hurt so it's not explicitly prevented if the driver supports hashing on both at the same time.

Document the USBHS controller for the Renesas RZ/T2H (r9a09g077) and RZ/N2H (r9a09g087) SoCs. While the USBHS block is similar to the one found on the RZ/G2L SoC, it differs slightly in terms of interrupt configuration, clock/reset requirements, and register bit definitions. Due to these differences, a new compatible string `renesas,usbhs-r9a09g077` is introduced for the RZ/T2H SoC. The USBHS controller on the RZ/N2H (r9a09g087) SoC is identical to that on the RZ/T2H, so it uses the `renesas,usbhs-r9a09g077` compatible string as a fallback.

2025-08-13cxl/region: Add inject and clear poison by region offsetAlison Schofield2-1/+88
Add CXL region debugfs attributes to inject and clear poison based on an offset into the region. These new interfaces allow users to operate on poison at the region level without needing to resolve Device Physical Addresses (DPA) or target individual memdevs. The implementation uses a new helper, region_offset_to_dpa_result() that applies decoder interleave logic, including XOR-based address decoding when applicable. Note that XOR decodes rely on driver internal xormaps which are not exposed to userspace. So, this support is not only a simplification of poison operations that could be done using existing per memdev operations, but also it enables this functionality for XOR interleaved regions for the first time. New debugfs attributes are added in /sys/kernel/debug/cxl/regionX/: inject_poison and clear_poison. These are only exposed if all memdevs participating in the region support both inject and clear commands, ensuring consistent and reliable behavior across multi-device regions. If tracing is enabled, these operations are logged as cxl_poison events in /sys/kernel/tracing/trace. The ABI documentation warns users of the significant risks that come with using these capabilities. A CXL Maturity Map update shows this user flow is now supported.

git://git.kernel.org/pub/scm/linux/kernel/git/mchehab/linux-docs into mauro Mauro says: As discussed at: https://lore.kernel.org/all/20250610101331.62ba466f@foz.lan/ changeset f061c9f7d058 ("Documentation: Document each netlink family") added a logic which generates *.rst files inside $(srctree). This is bad when O=<BUILDDIR> is used. A recent change renamed the yaml files used by Netlink, revealing a bad side effect: as "make cleandocs" don't clean the produced files and symbols appear duplicated for people that don't build the kernel from scratch. This series adds an yaml parser extension and uses an index file with glob for *. We opted to write such extension in a way that no actual yaml conversion code is inside it. This makes it flexible enough to handle other types of yaml files in the future. The actual yaml conversion logic were placed at netlink_yml_parser.py. As requested by YNL maintainers, this version has netlink_yml_parser.py inside tools/net/ynl/pyynl/ directory. I don't like mixing libraries with binaries, nor to have Python libraries spread all over the Kernel. IMO, the best is to put all of them on a common place (scripts/lib, python/lib, lib/python, ...) but, as this can be solved later, for now let's keep it this way.

2025-08-12sphinx: parser_yaml.py: fix line numbers informationMauro Carvalho Chehab1-7/+14
As reported by Donald, this code: rst_parser = RSTParser() rst_parser.parse('\n'.join(result), document) breaks line parsing. As an alternative, I tested a variant of it: rst_parser.parse(result, document) but still line number was not preserved. As Donald noted, standard Parser classes don't have a direct mechanism to preserve line numbers from ViewList(). So, instead, let's use a mechanism similar to what we do already at kerneldoc.py: call the statemachine mechanism directly there. I double-checked when states and statemachine were introduced: both were back in 2002. I also tested doc build with docutils 0.16 and 0.21.2. It worked with both, so it seems to be stable enough for our needs.
