2025-11-27ASoC: sdw_utils: Add cs42l45 support functionsCharles Keepax1-0/+2
Add the helper functions into the machine driver for the cs42l45, this will register a jack for jack detection and add things into to the components string if they are needed.

2025-11-27ASoC: intel: sof_sdw: Add ability to have auxiliary devicesCharles Keepax1-1/+10
Currently the sof_sdw machine driver assumes that all devices involved in the sound card are connected through a DAI link. However for SDCA devices we still want the HID (Human Interface Device, used for jack buttons) to be part of the sound card, but it contains no DAI links. Add support into the machine driver to specify a list of auxiliary devices to merged into the card.

2025-11-27ASoC: SDCA: Add terminal type into input/output widget nameCharles Keepax1-0/+2
There have been some complaints around the UCM files for SDCA devices that the control system is quite hard to follow. This is definitely true without the specification handy the naming can be a little cryptic. However, as most of the information is parsed from DisCo there are some limits to what the driver can safely do to improve this. However, one area that can be improved is the non-streaming input/output terminals. These have a field (enum sdca_terminal_type) that describes the usage of that terminal. These types can be appended to the entity name to give the users a better clue as to the purpose. For example "OT 43", would now become "OT 43 Headphone". This would follow through into the jack controls which would change from "OT 43 Jack" to "OT 43 Headphone Jack", making the purpose much more obvious to the user. This provides slightly more readable controls without relying on implicit knowledge that individual parts might not conform to.

2025-11-27ASoC: SDCA: Align mute controls to ALSA expectationsCharles Keepax1-1/+1
Currently mute controls will be called "FU xx Mute Switch" (note the switch is added programmatically outside the coverage of this patch) and the accompanying volume control would be called "FU xx Channel Volume". These names are taken from the SDCA specification, however, this does not mesh well with the ALSA naming system. ALSA generally expects enables rather than mutes and expects that mutes and volumes have matching names. Update the names and invert the mute controls to make them more standard "FU XX Channel Switch", this does slightly deviate from the SDCA specification but it makes the rest of the Linux ecosystem a lot happier.

2025-11-27srcu: Create an SRCU-fast-updown APIPaul E. McKenney3-7/+141
This commit creates an SRCU-fast-updown API, including DEFINE_SRCU_FAST_UPDOWN(), DEFINE_STATIC_SRCU_FAST_UPDOWN(), __init_srcu_struct_fast_updown(), init_srcu_struct_fast_updown(), srcu_read_lock_fast_updown(), srcu_read_unlock_fast_updown(), __srcu_read_lock_fast_updown(), and __srcu_read_unlock_fast_updown(). These are initially identical to their SRCU-fast counterparts, but both SRCU-fast and SRCU-fast-updown will be optimized in different directions by later commits. SRCU-fast will lack any sort of srcu_down_read() and srcu_up_read() APIs, which will enable extremely efficient NMI safety. For its part, SRCU-fast-updown will not be NMI safe, which will enable reasonably efficient implementations of srcu_down_read_fast() and srcu_up_read_fast(). This API fork happens to meet two different future use cases. * SRCU-fast will become the reimplementation basis for RCU-TASK-TRACE for consolidation. Since RCU-TASK-TRACE must be NMI safe, SRCU-fast must be as well. * SRCU-fast-updown will be needed for uretprobes code in order to get rid of the read-side memory barriers while still allowing entering the reader at task level while exiting it in a timer handler. This commit also adds rcutorture tests for the new APIs. This (annoyingly) needs to be in the same commit for bisectability. With this commit, the 0x8 value tests SRCU-fast-updown. However, most SRCU-fast testing will be via the RCU Tasks Trace wrappers.

2025-11-27net: pcs: xpcs: Add support for FBNIC 25G, 50G, 100G PMDAlexander Duyck1-0/+2
The fbnic driver is planning to make use of the XPCS driver to enable support for PCS and better integration with phylink. To do this though we will need to enable several workarounds since the PMD interface for fbnic is likely to be unique since it is a mix of two different vendor products with a unique wrapper around the IP. I have generated a PHY identifier based on IEEE 802.3-2022 22.2.4.3.1 using an OUI belonging to Meta Platforms and used with our NICs. Using this we will provide it as the PMD ID via the SW based MDIO interface so that the fbnic device can be identified and necessary workarounds enabled in the XPCS driver. As an initial workaround this change adds an exception so that soft_reset is not set when the driver is initially bound to the PCS. In addition I have added logic to integrate the PMD Rx signal detect state into the link state for the PCS. With this we can avoid the link coming up too soon on the FBNIC PMD and as a result of it being in the training state so we can avoid link flaps.

2025-11-27net: pcs: xpcs: Fix PMA identifier handling in XPCSAlexander Duyck2-1/+6
The XPCS driver was mangling the PMA identifier as the original code appears to have been focused on just capturing the OUI. Rather than store a mangled ID it is better to work with the actual PMA ID and instead just mask out the values that don't apply rather than shifting them and reordering them as you still don't get the original OUI for the NIC without having to bitswap the values as per the definition of the layout in IEEE 802.3-2022 22.2.4.3.1. By laying it out as it was in the hardware it is also less likely for us to have an unintentional collision as the enum values will occupy the revision number area while the OUI occupies the upper 22 bits.

With this change we are adding support for 25G, 50G, and 100G interface types to the XPCS driver. This had supposedly been enabled with the addition of XLGMII but I don't see any capability for configuration there so I suspect it may need to be refactored in the future. With this change we can enable the XPCS driver with the selected interface and it should be able to detect link, speed, and report the link status to the phylink interface.

2025-11-26virtio-net: avoid unnecessary checksum calculation on guest RXJon Kohler1-3/+4
Commit a2fb4bc4e2a6 ("net: implement virtio helpers to handle UDP GSO tunneling.") inadvertently altered checksum offload behavior for guests not using UDP GSO tunneling. Before, tun_put_user called tun_vnet_hdr_from_skb, which passed has_data_valid = true to virtio_net_hdr_from_skb. After, tun_put_user began calling tun_vnet_hdr_tnl_from_skb instead, which passes has_data_valid = false into both call sites. This caused virtio hdr flags to not include VIRTIO_NET_HDR_F_DATA_VALID for SKBs where skb->ip_summed == CHECKSUM_UNNECESSARY. As a result, guests are forced to recalculate checksums unnecessarily. Restore the previous behavior by ensuring has_data_valid = true is passed in the !tnl_gso_type case, but only from tun side, as virtio_net_hdr_tnl_from_skb() is used also by the virtio_net driver, which in turn must not use VIRTIO_NET_HDR_F_DATA_VALID on tx. cc: stable@vger.kernel.org Fixes: a2fb4bc4e2a6 ("net: implement virtio helpers to handle UDP GSO tunneling.")

2025-11-26of: Add wrappers to match root node with OF device ID tablesKrzysztof Kozlowski1-0/+13
Several drivers duplicate same code for getting reference to the root node, matching it against 'struct of_device_id' table and getting out the match data from the table entry. There is a of_machine_compatible_match() wrapper but it takes array of strings, which is not suitable for many drivers since they want the driver data associated with each compatible. Add two wrappers, similar to existing of_device_get_match_data(): 1. of_machine_device_match() doing only matching against 'struct of_device_id' and returning bool. 2. of_machine_get_match_data() doing the matching and returning associated driver data for found compatible.

2025-11-26libceph: drop started parameter of __ceph_open_session()Ilya Dryomov1-2/+1
With the previous commit revamping the timeout handling, started isn't used anymore. It could be taken into account by adjusting the initial value of the timeout, but there is little point as both callers capture the timestamp shortly before calling __ceph_open_session() -- the only thing of note that happens in the interim is taking client->mount_mutex and that isn't expected to take multiple seconds.

2025-11-26drm/colorop: Add PQ 125 EOTF and its inverseHarry Wentland1-0/+24
The PQ function defines a mapping of code values to nits (cd/m^2). The max code value maps to 10,000 nits. Windows DWM's canonical composition color space (CCCS) defaults to composing SDR contents to 80 nits and uses a float value of 1.0 to represent this. For this reason AMD HW hard-codes a PQ function that is scaled by 125, yielding 80 nit PQ values for 1.0 and 10,000 nits at 125.0. This patch introduces this scaled PQ EOTF and its inverse as 1D curve types.
