net: ti: icssg-prueth: Use page_pool API for RX buffer allocationThis is to prepare for native XDP support.The page pool API is more faster in allocating pages than__alloc_skb(). Drawback is that it works at PAGE_SIZE granularityso we are not efficient in memory usage.i.e. we are using PAGE_SIZE (4KB) memory for 1.5KB max packet size.Signed-off-by: Roger Quadros Signed-off-by: MD Danish Anwar Signed-off-by: Meghana Malladi Link: https://patch.msgid.link/20250305101422.1908370-2-m-malladi@ti.comSigned-off-by: Paolo Abeni List of files: /linux-6.15/drivers/net/ethernet/ti/Kconfig

bc8d62e1 - net: ethernet: ti: am65-cpsw: add mqprio qdisc offload in channel mode

Tue, 19 Dec 2023 10:58:03 +0000

net: ethernet: ti: am65-cpsw: add mqprio qdisc offload in channel modeThis patch adds MQPRIO Qdisc offload in full 'channel' mode which allowsnot only setting up pri:tc mapping, but also configuring TX shapers(rate-limiting) on external port FIFOs.The MQPRIO Qdisc offload is expected to work with or without VLAN/prioritytagged packets.The CPSW external Port FIFO has 8 Priority queues. The rate-limit can beset for each of these priority queues. Which Priority queue a packet isassigned to depends on PN_REG_TX_PRI_MAP register which maps headerpriority to switch priority.The header priority of a packet is assigned via the RX_PRI_MAP_REG whichmaps packet priority to header priority.The packet priority is either the VLAN priority (for VLAN tagged packets)or the thread/channel offset.For simplicity, we assign the same priority queue to all queues of aTraffic Class so it can be rate-limited correctly.Configuration example: ethtool -L eth1 tx 5 ethtool --set-priv-flags eth1 p0-rx-ptype-rrobin off tc qdisc add dev eth1 parent root handle 100: mqprio num_tc 3 \ map 0 0 1 2 0 0 0 0 0 0 0 0 0 0 0 0 \ queues 1@0 1@1 1@2 hw 1 mode channel \ shaper bw_rlimit min_rate 0 100mbit 200mbit max_rate 0 101mbit 202mbit tc qdisc replace dev eth2 handle 100: parent root mqprio num_tc 1 \ map 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 queues 1@0 hw 1 ip link add link eth1 name eth1.100 type vlan id 100 ip link set eth1.100 type vlan egress 0:0 1:1 2:2 3:3 4:4 5:5 6:6 7:7In the above example two ports share the same TX CPPI queue 0 for lowpriority traffic. 3 traffic classes are defined for eth1 and mapped to:TC0 - low priority, TX CPPI queue 0 -> ext Port 1 fifo0, no rate limitTC1 - prio 2, TX CPPI queue 1 -> ext Port 1 fifo1, CIR=100Mbit/s, EIR=1Mbit/sTC2 - prio 3, TX CPPI queue 2 -> ext Port 1 fifo2, CIR=200Mbit/s, EIR=2Mbit/sSigned-off-by: Grygorii Strashko Signed-off-by: Roger Quadros Reviewed-by: Vladimir Oltean Signed-off-by: David S.

This subsystem is provided for the use cases like implementation ofcustom peripheral interfaces, offloading of tasks from the otherprocessor cores of the SoC, etc.Every ICSSG core has two Programmable Real-Time Unit(PRUs),two auxiliary Real-Time Transfer Unit (RT_PRUs), andtwo Transmit Real-Time Transfer Units (TX_PRUs). Each one of these runsits own firmware. Every ICSSG core has two MII ports connect to thesePRUs and also a MDIO port.The cores can run different firmwares to support different protocols andfeatures like switch-dev, timestamping, etc.It uses System DMA to transfer and receive packets andshared memory register emulation between the firmware anddriver for control and configuration.This patch adds support for basic EMAC functionality with 1Gbpsand 100Mbps link speed. 10M and half duplex mode are not supportedcurrently as they require IEP, the support for which will be added later.Support for switch-dev, timestamp, etc. will be added laterby subsequent patch series.Signed-off-by: Roger Quadros Signed-off-by: Vignesh Raghavendra Signed-off-by: Grygorii Strashko Reviewed-by: Andrew Lunn Signed-off-by: MD Danish Anwar Signed-off-by: David S.
