2025-01-17mlxsw: Move Tx header handling to PCI driverAmit Cohen
Tx header should be added to all packets transmitted from the CPU to Spectrum ASICs. Historically, handling this header was added as a driver function, as Tx header is different between Spectrum and Switch-X. See SwitchX implementation in commit 31557f0f9755 ("mlxsw: Introduce Mellanox SwitchX-2 ASIC support"). From May 2021, there is no support for SwitchX-2 ASIC, and all the relevant code was removed. For now, there is no justification to handle Tx header as part of spectrum.c, we can handle this as part of PCI, in skb_transmit(). A future patch set will add support for XDP in mlxsw driver, to support XDP_TX and XDP_REDIRECT actions, Tx header should be added before transmitting the packet. As preparation for this, move Tx header handling to PCI driver, so then XDP code will not have to call API from spectrum.c. This also improves the code as now Tx header is pushed just before transmitting, so it is not done from many flows which might miss something. Note that for PTP, we should configure Tx header differently, use the fields from mlxsw_txhdr_info to configure the packets correctly in PCI driver. Handle VLAN tagging in switch driver, verify that packet which should be transmitted as data is tagged, otherwise, tag it. Remove the calls for thxdr_construct() functions, as now this is done as part of skb_transmit().

2025-01-17mlxsw: Define Tx header fields in txheader.hAmit Cohen
The next patch will move Tx header constructing to pci.c. As preparation, move the definitions of Tx header fields from spectrum.c to txheader.h, so pci.c will include this header and can access the fields. Remove 'etclass' which is not used.

2025-01-17mlxsw: Initialize txhdr_info according to PTP operationsAmit Cohen
A next patch will construct Tx header as part of pci.c. The switch driver (mlxsw_spectrum.ko) should encapsulate all the differences between the different ASICs and the bus driver (mlxsw_pci.ko) should remain unaware. As preparation, add the relevant info as part of mlxsw_txhdr_info structure, so later bus driver will merely construct the Tx header based on information passed from the switch driver. Most of the packets are transmitted as control packets, but PTP packets in Spectrum-2 and Spectrum-3 should be handled differently. The driver transmits them as data packets, and the default VLAN tag (4095) is added if the packet is not already tagged. Extend PTP operations to store a boolean which indicates whether packets should be transmitted as data packets. Set it for Spectrum-2 and Spectrum-3 only. Extend mlxsw_txhdr_info to store fields which will be used later to construct Tx header. Initialize such fields according to the new boolean which is stored in PTP operations. Note that for now, mlxsw_txhdr_info structure is initialized, but not used, a next patch will use it.

2025-01-17mlxsw: Add mlxsw_txhdr_info structureAmit Cohen
mlxsw_tx_info structure is used to store information that is needed to process Tx completions when Tx time stamps are requested. A next patch will move Tx header handling from spectrum.c to pci.c. For that, some additional fields which are related to Tx should be passed to pci driver. As preparation, create an extended structure, called mlxsw_txhdr_info, and store mlxsw_tx_info inside. The new fields should not be added to mlxsw_tx_info structure as it is stored in the SKB control block which is of limited size. The next patch will extend the new structure with some fields which are needed in order to construct Tx header.

2025-01-17net/mlx5: fix unintentional sign extension on shift of dest_attr->vport.vhca_idColin Ian King
Shifting dest_attr->vport.vhca_id << 16 results in a promotion from an unsigned 16 bit integer to a 32 bit signed integer, this is then sign extended to a 64 bit unsigned long on 64 bitarchitectures. If vhca_id is greater than 0x7fff then this leads to a sign extended result where all the upper 32 bits of idx are set to 1. Fix this by casting vhca_id to the same type as idx before performing the shift.

2025-01-17dm-transaction-manager: use red-black trees instead of linear listsMikulas Patocka
There was reported performance degradation when the shadow map contained too many entries [1]. The shadow map uses 256-bucket hash with linear lists - when there are too many entries, it has quadratic complexity. Meir Elisha proposed to add a module parameter that could configure the size of the hash array - however, this is not ideal because users don't know that they should increase the parameter when they get bad performance. This commit replaces the linear lists with rb-trees (so that there's a hash of rb-trees), they have logarithmic complexity, so it solves the performance degradation.

Currently only stacked devices need to explicitly enable atomic writes by setting BLK_FEAT_ATOMIC_WRITES_STACKED flag. This does not work well for device mapper stacking devices, as there many sets of limits are stacked and what is the 'bottom' and 'top' device can swapped. This means that BLK_FEAT_ATOMIC_WRITES_STACKED needs to be set for many queue limits, which is messy.

2025-01-17cpufreq: Use str_enable_disable()-like helpersKrzysztof Kozlowski
Replace ternary (condition ? "enable" : "disable") syntax with helpers from string_choices.h because: 1. Simple function call with one argument is easier to read. Ternary operator has three arguments and with wrapping might lead to quite long code. 2. Is slightly shorter thus also easier to read. 3. It brings uniformity in the text - same string. 4. Allows deduping by the linker, which results in a smaller binary file.
