2024-07-14Bluetooth: btintel_pcie: Remove unnecessary memset(0) callsThorsten Blum

2024-07-14Bluetooth: Use sizeof(*pointer) instead of sizeof(type)Erick Archer
It is preferred to use sizeof(*pointer) instead of sizeof(type) due to the type of the variable can change and one needs not change the former (unlike the latter).

2024-07-14net: netconsole: Disable target before netpoll cleanupBreno Leitao
Currently, netconsole cleans up the netpoll structure before disabling the target. This approach can lead to race conditions, as message senders (write_ext_msg() and write_msg()) check if the target is enabled before using netpoll. The sender can validate that the target is enabled, but, the netpoll might be de-allocated already, causing undesired behaviours. This patch reverses the order of operations: 1. Disable the target 2. Clean up the netpoll structure This change eliminates the potential race condition, ensuring that no messages are sent through a partially cleaned-up netpoll structure.

In many cases this can decrease the number of recipes required to add a certain set of rules, potentially allowing a more varied set of rules to be created. Total rule count will also increase, since less words will be left unused/wasted. There are only 64 rules available in total, so every one counts.

This patch implements the TDR test procedure as described in "Application Note DP83TD510E Cable Diagnostics Toolkit revC", section 3.2. The procedure was tested with "draka 08 signalkabel 2x0.8mm". The reported cable length was 5 meters more for each 20 meters of actual cable length. For instance, a 20-meter cable showed as 25 meters, and a 40-meter cable showed as 50 meters. Since other parts of the diagnostics provided by this PHY (e.g., Active Link Cable Diagnostics) require accurate cable characterization to provide proper results, this tuning can be implemented in a separate patch/interface.

2024-07-13eth: mlx5: expose NETIF_F_NTUPLE when ARFS is compiled outJakub Kicinski
ARFS depends on NTUPLE filters, but the inverse is not true. Drivers which don't support ARFS commonly still support NTUPLE filtering. mlx5 has a Kconfig option to disable ARFS (MLX5_EN_ARFS) and does not advertise NTUPLE filters as a feature at all when ARFS is compiled out. That's not correct, ntuple filters indeed still work just fine (as long as MLX5_EN_RXNFC is enabled). This is needed to make the RSS test not skip all RSS context related testing.

New Support: - Added support for Intel Arrow Lake-H. - Added I2C support in the Arioha SoC by linking the Mediatek I2C controller. Cleanups: - Added the MODULE_DESCRIPTION() macro, resolving a modpost warning in the ALi 1563 Southbridge driver. - Constified the regmap_config declaration in the i2c-designware driver. - Improved the coding style in the Renesas R-Car driver by removing unnecessary semicolons after brackets. General improvements: - In the OMAP device, replaced NOIRQ_SYSTEM_SLEEP_PM_OPS with RUNTIME_PM_OPS to enable waking up the controller during suspend() before suspend_noirq() kicks in. - Improved logging in the Xilinx driver. - Added a warning (WARN()) in the Renesas R-Car driver for spurious interrupts. DTS Changes: - Removed address-cell and size-cell from the Atmel at91sam, nVidia Tegra 20, and Samsung S3c2410 devices. - Fixed Texas Instruments OMAP4 I2C controller to comply with the i2c-controller.yaml schema. - Improved indentation in DTS examples for several I2C devices. - Converted the NXP LPC1788 binding to the dt-schema. - Added documentation for the compatible string thead,th1520-i2c. - Added the "power-domains" property for the Meson I2C driver.

bnxt allocates tables of max size, and changes the used size based on number of active rings. The unused entries get padded out with zeros. bnxt_modify_rss() seems to always pad out the table of the main / default RSS context, instead of the table of the modified context. I haven't observed any behavior change due to this patch, so I don't think it's a fix. Not entirely sure what role the padding plays, 0 is a valid queue ID.
