Tariq Toukan says: ==================== Compile-flag for sock RX queue mapping Socket's RX queue mapping logic is useful also for non-XPS use cases. This series breaks the dependency between the two, introducing a new kernel config flag SOCK_RX_QUEUE_MAPPING. Here we select this new kernel flag from TLS_DEVICE, as well as XPS. ==================== Acked-by:Jakub Kicinski <kuba@kernel.org>

Use a new config SOCK_RX_QUEUE_MAPPING to compile-in the socket RX queue field and logic, instead of the XPS config. This breaks dependency in XPS, and allows selecting it from non-XPS use cases, as we do in the next patch. In addition, use the new flag to wrap the logic in sk_rx_queue_get() and protect access to the sk_rx_queue_mapping field, while keeping the function exposed unconditionally, just like sk_rx_queue_set() and sk_rx_queue_clear().

dev_ifsioc_locked() is called with only RCU read lock, so when there is a parallel writer changing the mac address, it could get a partially updated mac address, as shown below: Thread 1 Thread 2 // eth_commit_mac_addr_change() memcpy(dev->dev_addr, addr->sa_data, ETH_ALEN); // dev_ifsioc_locked() memcpy(ifr->ifr_hwaddr.sa_data, dev->dev_addr,...); Close this race condition by guarding them with a RW semaphore, like netdev_get_name(). We can not use seqlock here as it does not allow blocking. The writers already take RTNL anyway, so this does not affect the slow path. To avoid bothering existing dev_set_mac_address() callers in drivers, introduce a new wrapper just for user-facing callers on ioctl and rtnetlink paths. Note, bonding also changes slave mac addresses but that requires a separate patch due to the complexity of bonding code. Fixes: 3710becf ("net: RCU locking for simple ioctl()") Reported-by:

The condition should be skipped if CPU ID equal to nthreads. The patch doesn't fix any actual issue since nthreads = min_t(unsigned int, num_present_cpus(), MVPP2_MAX_THREADS).

J721e, J7200 and AM64 have multi port switches which can work in multi mac mode and in switch mode. Add support for configuring this HW in switch mode using devlink and switchdev notifiers. Support is similar to existing CPSW switchdev implementation of TI's 32 bit platform like AM33/AM43/AM57. To enable switch mode: devlink dev param set platform/8000000.ethernet name switch_mode value true cmode runtime All configuration is implemented via switchdev API and notifiers. Supported: - SWITCHDEV_ATTR_ID_PORT_PRE_BRIDGE_FLAGS - SWITCHDEV_ATTR_ID_PORT_BRIDGE_FLAGS - SWITCHDEV_ATTR_ID_PORT_STP_STATE - SWITCHDEV_OBJ_ID_PORT_VLAN - SWITCHDEV_OBJ_ID_PORT_MDB - SWITCHDEV_OBJ_ID_HOST_MDB Hence AM65 CPSW switchdev driver supports: - FDB offloading - MDB offloading - VLAN filtering and offloading - STP Signed-off-by: -

Vignesh Raghavendra authored
AM65 NUSS ethernet switch on K3 devices can be configured to work either in independent mac mode where each port acts as independent network interface (multi mac) or switch mode. Add devlink hooks to provide a way to switch b/w these modes. Rationale to use devlink instead of defaulting to bridge mode is that SoC use cases require to support multiple independent MAC ports with no switching so that users can use software bridges with multi-mac configuration (e.g: to support LAG, HSR/PRP, etc). Also, switching between multi mac and switch mode requires significant Port and ALE reconfiguration, therefore is easier to be made as part of mode change devlink hooks. It also allows to keep user interface similar to what was implemented for the previous generation of TI CPSW IP (on AM33/AM43/AM57 SoCs). Signed-off-by:

Geetha sowjanya says: ==================== Add Marvell CN10K support The current admin function (AF) driver and the netdev driver supports OcteonTx2 silicon variants. The same OcteonTx2's Resource Virtualization Unit (RVU) is carried forward to the next-gen silicon ie OcteonTx3, with some changes and feature enhancements. This patch set adds support for OcteonTx3 (CN10K) silicon and gets the drivers to the same level as OcteonTx2. No new OcteonTx3 specific features are added. Changes cover below HW level differences - PCIe BAR address changes wrt shared mailbox memory region - Receive buffer freeing to HW - Transmit packet's descriptor submission to HW - Programmable HW interface identifiers (channels) - Increased MTU support - A Serdes MAC block (RPM) configuration v5-v6 Rebased on top of latest net-next branch. v4-v5 Fixed sparse warnings. v3-v4 Fixed compiler warnings. v2-v3 Reposting as a single thread. Rebased on top latest net-next branch. v1-v2 Fixed check-patch reported issues. ==================== Signed-off-by: -

MAC on CN10K silicon support loopback for selftest or debug purposes. This patch does necessary configuration to loopback packets upon receiving request from LMAC mapped RVU PF's netdev via mailbox. Also MAC (CGX) on OcteonTx2 silicon variants and MAC (RPM) on OcteonTx3 CN10K are different and loopback needs to be configured differently. Upper layer interface between RVU AF and PF netdev is kept same. Based on silicon variant appropriate fn() pointer is called to config the MAC. Signed-off-by:

OcteonTx3 CN10K silicon supports bigger MTU when compared to 9216 MTU supported by OcteonTx2 silicon variants. Lookback interface supports upto 64K and RPM LMAC interfaces support upto 16K.

NIX uses unique channel numbers to identify the packet sources/sinks like CGX,LBK and SDP. The channel numbers assigned to each block are hardwired in CN9xxx silicon. The fixed channel numbers in CN9xxx are: 0x0 | a << 8 | b - LBK(0..3)_CH(0..63) 0x0 | a << 8 - Reserved 0x700 | a - SDP_CH(0..255) 0x800 | a << 8 | b << 4 | c - CGX(0..7)_LMAC(0..3)_CH(0..15) All the channels in the above fixed enumerator(with maximum number of blocks) are not required since some chips have less number of blocks. For CN10K silicon the channel numbers need to be programmed by software in each block with the base channel number and range of channels. This patch calculates and assigns the channel numbers to efficiently distribute the channel number range(0-4095) among all the blocks. The assignment is made based on the actual number of blocks present and also contiguously leaving no holes. The channel numbers remaining after the math are used as new CPT replay channels present in CN10K. Also since channel numbers are not fixed the transmit channel link number needed by AF consumers is calculated by AF and sent along with nix_lf_alloc mailbox response. Signed-off-by:

OcteonTx2's next gen platform the CN10K has RPM MAC which has a different serdes when compared to CGX MAC. Though the underlying HW is different, the CSR interface has been designed largely inline with CGX MAC, with few exceptions though. So we are using the same CGX driver for RPM MAC as well and will have a different set of APIs for RPM where ever necessary. This patch adds initial support for CN10K's RPM MAC i.e. the driver registration, communication with firmware etc. For communication with firmware, RPM provides a different IRQ when compared to CGX. The CGX and RPM blocks support different features. Currently few features like ptp, flowcontrol and higig are not supported by RPM. This patch adds new mailbox message "CGX_FEATURES_GET" to get the list of features supported by underlying MAC. RPM has different implementations for RX/TX stats. Unlike CGX, bar offset of stat registers are different. This patch adds support to access the same and dump the values in debugfs. Signed-off-by:
