net: ti: icssg-prueth: Add ICSSG StatsAdd icssg_stats.c to help dump, icssg related driver statistics.ICSSG has hardware registers for providing statistics like total rx bytes,total tx bytes, etc. These registers are of 32 bits and hence in case of 1Glink, they overflows in around 32 seconds. The behaviour of these registersis such that they don't roll back to 0 after overflow but rather stay atUINT_MAX.These registers support a feature where the value written to them issubtracted from the register. This feature can be utilized to fix theoverflowing of stats.This solution uses a Workqueues based solution where a function getscalled before the registers overflow (every 25 seconds in 1G link, 25000seconds in 100M link), this function saves the registervalues in local variables and writes the last read value to theregister. So any update during the read will be taken care of.Signed-off-by: MD Danish Anwar Signed-off-by: David S. Miller List of files: /linux-6.15/drivers/net/ethernet/ti/Makefile

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.

8127224c - ethernet: ti: am65-cpsw-qos: add TAPRIO offload support

Wed, 13 May 2020 13:26:15 +0000

ethernet: ti: am65-cpsw-qos: add TAPRIO offload supportAM65 CPSW h/w supports Enhanced Scheduled Traffic (EST – definedin P802.1Qbv/D2.2 that later got included in IEEE 802.1Q-2018)configuration. EST allows express queue traffic to be scheduled(placed) on the wire at specific repeatable time intervals. InLinux kernel, EST configuration is done through tc command andthe taprio scheduler in the net core implements a software onlyscheduler (SCH_TAPRIO). If the NIC is capable of EST configuration,user indicate "flag 2" in the command which is then parsed bytaprio scheduler in net core and indicate that the command is tobe offloaded to h/w. taprio then offloads the command to thedriver by calling ndo_setup_tc() ndo ops. This patch implementsndo_setup_tc() to offload EST configuration to CPSW h/w.Currently driver supports only SetGateStates operation. ESToperates on a repeating time interval generated by the CPTS ESTfunction generator. Each Ethernet port has a global EST fetchRAM that can be configured as 2 buffers, each of 64 locationsor one large buffer of 128 locations. In 2 buffer configuration,a ping pong mechanism is used to hold the active schedule (oper)in one buffer and new (admin) command in the other. Each 22-bitfetch command consists of a 14-bit fetch count (14 MSB’s) and an8-bit priority fetch allow (8 LSB’s) that will be applied for thefetch count time in wireside clocks. Driver process each of thesched-entry in the offload command and update the fetch RAM.Driver configures duration in sched-entry into the fetch countand Gate mask into the priority fetch bits of the RAM. Thenconfigures the CPTS EST function generator to activate theschedule. Currently driver supports only 2 buffer configurationwhich means driver supports a max cycle time of ~8 msec.CPSW supports a configurable number of priority queues (up to 8)and needs to be switched to this mode from the default roundrobin mode before EST can be offloaded. User configuresthese through ethtool commands (-L for changing number ofqueues and --set-priv-flags to disable round robin mode).Driver doesn't enable EST if pf_p0_rx_ptype_rrobin privat flagis set. The flag is common for all ports, and so can't be justoverridden by taprio configuration w/o user involvement.Command fails if pf_p0_rx_ptype_rrobin is already set in thedriver.Scheds (commands) configuration depends on interface speed sodriver translates the duration to the fetch count based onlink speed. Each schedule can be constructed with severalcommand entries in fetch RAM depending on interval. For exampleif each sched has timer interval < ~130us on 1000 Mb link theneach sched consumes one command and have 1:1 mapping. WhenEthernet link goes down, driver purge the configuration if linkis down for more than 1 second.The patch allows to update the timer and scheds memory only if it'sreally needed, and skip cases required the user to stop timer byconfiguring only shceds memory.Signed-off-by: Ivan Khoronzhuk Signed-off-by: Murali Karicheri Signed-off-by: David S.

92db978f - net: ethernet: ti: Remove TI_CPTS_MOD workaround

Tue, 12 May 2020 10:02:30 +0000

net: ethernet: ti: Remove TI_CPTS_MOD workaroundMy recent commit b6d49cab44b5 ("net: Make PTP-specific drivers depend onPTP_1588_CLOCK") exposes a missing dependency in defconfigs that selectTI_CPTS without selecting PTP_1588_CLOCK, leading to linker errors of theform:drivers/net/ethernet/ti/cpsw.o: in function `cpsw_ndo_stop':cpsw.c:(.text+0x680): undefined reference to `cpts_unregister' ...That's because TI_CPTS_MOD (which is the symbol gating the _compilation_ ofcpts.c) now depends on PTP_1588_CLOCK, and so is not enabled in theseconfigurations, but TI_CPTS (which is the symbol gating _calls_ to the cptsfunctions) _is_ enabled. So we end up compiling calls to functions thatdon't exist, resulting in the linker errors.This patch fixes build errors and restores previous behavior by: - ensure PTP_1588_CLOCK=y in TI specific configs and CPTS will be built - remove TI_CPTS_MOD and, instead, add dependencies from CPTS in TI_CPSW/TI_KEYSTONE_NETCP/TI_CPSW_SWITCHDEV as below: config TI_CPSW_SWITCHDEV ... depends on TI_CPTS || !TI_CPTS which will ensure proper dependencies PTP_1588_CLOCK -> TI_CPTS ->TI_CPSW/TI_KEYSTONE_NETCP/TI_CPSW_SWITCHDEV and build type selection.Note.
