2024-01-22ASoC: qcom: sc8280xp: limit speaker volumesJohan Hovold
The UCM configuration for the Lenovo ThinkPad X13s has up until now been setting the speaker PA volume to the minimum -3 dB when enabling the speakers, but this does not prevent the user from increasing the volume further. Limit the digital gain and PA volumes to a combined -3 dB in the machine driver to reduce the risk of speaker damage until we have active speaker protection in place (or higher safe levels have been established). Note that the PA volume limit cannot be set lower than 0 dB or PulseAudio gets confused when the first 16 levels all map to -3 dB. Also note that this will probably need to be generalised using machine-specific limits, but a common limit should do for now.

2024-01-22cxl/pci: Skip irq features if MSI/MSI-X are not supportedIra Weiny
CXL 3.1 Section 3.1.1 states: "A Function on a CXL device must not generate INTx messages if that Function participates in CXL.cache protocol or CXL.mem protocols." The generic CXL memory driver only supports devices which use the CXL.mem protocol. The current driver attempts to allocate MSI/MSI-X vectors in anticipation of their need for mailbox interrupts or event processing. However, the above requirement does not require a device to support interrupts, only that they use MSI/MSI-X. For example, a device may disable mailbox interrupts and either be configured for firmware first or skip event processing and function. Dave Larsen reported that the following Intel / Agilex card does not support interrupts on function 0. CXL: Intel Corporation Device 0ddb (rev 01) (prog-if 10 [CXL Memory Device (CXL 2.x)]) Rather than fail device probe if interrupts are not supported; flag that irqs are not enabled and avoid features which require interrupts. Emit messages appropriate for the situation to aid in debugging should device behavior be unexpected due to a failure to allocate vectors. Note that it is possible for a device to have host based event processing through polling. However, the driver does not support polling and it is not anticipated to be generally required. Leave that functionality to a future patch if such a device comes along.

2024-01-22bcachefs: fix incorrect usage of REQ_OP_FLUSHChristoph Hellwig
REQ_OP_FLUSH is only for internal use in the blk-mq and request based drivers. File systems and other block layer consumers must use REQ_OP_WRITE | REQ_PREFLUSH as documented in Documentation/block/writeback_cache_control.rst. While REQ_OP_FLUSH appears to work for blk-mq drivers it does not get the proper flush state machine handling, and completely fails for any bio based drivers, including all the stacking drivers. The block layer will also get a check in 6.8 to reject this use case entirely.

2024-01-22Improve SOF support for Steam Deck OLEDMark Brown
Merge series from Cristian Ciocaltea <cristian.ciocaltea@collabora.com>: This patch series is a continuation of [1] to provide several fixes and improvements to the SOF drivers targeting the Vangogh platform, as found on Valve's Steam Deck OLED. The previous series only handled the legacy ACP drivers. Also note that, since v2, this patch series requires an updated SOF topology to provide a correct DAI link ID for the BT codec. The binary file should be located under: /usr/lib/firmware/amd/sof-tplg/sof-vangogh-nau8821-max.tplg Alternatively, as a temporary workaround, patch [2] can be used to adapt the driver to the broken topology. Another requirement to get this functional is patch [3] from v1, which has been dropped from the series to be upstreamed via the SOF development workflow.

2024-01-22ASoC: codecs: lpass-wsa-macro: fix compander volume hackJohan Hovold
The LPASS WSA macro codec driver is updating the digital gain settings behind the back of user space on DAPM events if companding has been enabled. As compander control is exported to user space, this can result in the digital gain setting being incremented (or decremented) every time the sound server is started and the codec suspended depending on what the UCM configuration looks like. Soon enough playback will become distorted (or too quiet). This is specifically a problem on the Lenovo ThinkPad X13s as this bypasses the limit for the digital gain setting that has been set by the machine driver. Fix this by simply dropping the compander gain offset hack. If someone cares about modelling the impact of the compander setting this can possibly be done by exporting it as a volume control later. Note that the volume registers still need to be written after enabling clocks in order for any prior updates to take effect.

Several inlined functions subject to paravirt patching are referencing BUG_func() after the recent switch to the alternative patching mechanism. As those functions can legally be used by non-GPL modules, BUG_func() must be usable by those modules, too. So use EXPORT_SYMBOL() when exporting BUG_func().

2024-01-22cpufreq: intel_pstate: Refine computation of P-state for given frequencyRafael J. Wysocki
On systems using HWP, if a given frequency is equal to the maximum turbo frequency or the maximum non-turbo frequency, the HWP performance level corresponding to it is already known and can be used directly without any computation. Accordingly, adjust the code to use the known HWP performance levels in the cases mentioned above. This also helps to avoid limiting CPU capacity artificially in some cases when the BIOS produces the HWP_CAP numbers using a different E-core-to-P-core performance scaling factor than expected by the kernel.

Syzcaller UBSAN crash occurs in rds_cmsg_recv(), which reads inc->i_rx_lat_trace[j + 1] with index 4 (3 + 1), but with array size of 4 (RDS_RX_MAX_TRACES).

2024-01-22platform/mellanox: mlxbf-tmfifo: Drop Tx network packet when Tx TmFIFO is fullLiming Sun
Starting from Linux 5.16 kernel, Tx timeout mechanism was added in the virtio_net driver which prints the "Tx timeout" warning message when a packet stays in Tx queue for too long. Below is an example of the reported message: "[494105.316739] virtio_net virtio1 tmfifo_net0: TX timeout on queue: 0, sq: output.0, vq: 0×1, name: output.0, usecs since last trans: 3079892256". This issue could happen when external host driver which drains the FIFO is restared, stopped or upgraded. To avoid such confusing "Tx timeout" messages, this commit adds logic to drop the outstanding Tx packet if it's not able to transmit in two seconds due to Tx FIFO full, which can be considered as congestion or out-of-resource drop. This commit also handles the special case that the packet is half- transmitted into the Tx FIFO. In such case, the packet is discarded with remaining length stored in vring->rem_padding. So paddings with zeros can be sent out when Tx space is available to maintain the integrity of the packet format. The padded packet will be dropped on the receiving side.

2024-01-22net: micrel: Fix PTP frame parsing for lan8814Horatiu Vultur
The HW has the capability to check each frame if it is a PTP frame, which domain it is, which ptp frame type it is, different ip address in the frame. And if one of these checks fail then the frame is not timestamp. Most of these checks were disabled except checking the field minorVersionPTP inside the PTP header. Meaning that once a partner sends a frame compliant to 8021AS which has minorVersionPTP set to 1, then the frame was not timestamp because the HW expected by default a value of 0 in minorVersionPTP. This is exactly the same issue as on lan8841. Fix this issue by removing this check so the userspace can decide on this.

2024-01-22dpll: fix register pin with unregistered parent pinArkadiusz Kubalewski
In case of multiple kernel module instances using the same dpll device: if only one registers dpll device, then only that one can register directly connected pins with a dpll device. When unregistered parent is responsible for determining if the muxed pin can be registered with it or not, the drivers need to be loaded in serialized order to work correctly - first the driver instance which registers the direct pins needs to be loaded, then the other instances could register muxed type pins. Allow registration of a pin with a parent even if the parent was not yet registered, thus allow ability for unserialized driver instance load order. Do not WARN_ON notification for unregistered pin, which can be invoked for described case, instead just return error.

If parent pin was unregistered but child pin was not, the userspace would see the "zombie" pins - the ones that were registered with a parent pin (dpll_pin_on_pin_register(..)). Technically those are not available - as there is no dpll device in the system. Do not dump those pins and prevent userspace from any interaction with them. Provide a unified function to determine if the pin is available and use it before acting/responding for user requests.
