net: ti: icssg-prueth: Add optional dependency on HSR

2026-03-04T12:21:27Z

[ Upstream commit e3998b6e90f875f19bf758053d79ccfd41880173 ] Commit 95540ad6747c ("net: ti: icssg-prueth: Add support for HSR frame forward offload") introduced support for offloading HSR frame forwarding, which relies on functions such as is_hsr_master() provided by the HSR module. Although HSR provides stubs for configurations with HSR disabled, this driver still requires an optional dependency on HSR. Otherwise, build failures will occur when icssg-prueth is built-in while HSR is configured as a module. ld.lld: error: undefined symbol: is_hsr_master >>> referenced by icssg_prueth.c:710 (drivers/net/ethernet/ti/icssg/icssg_prueth.c:710) >>> drivers/net/ethernet/ti/icssg/icssg_prueth.o:(icssg_prueth_hsr_del_mcast) in archive vmlinux.a >>> referenced by icssg_prueth.c:681 (drivers/net/ethernet/ti/icssg/icssg_prueth.c:681) >>> drivers/net/ethernet/ti/icssg/icssg_prueth.o:(icssg_prueth_hsr_add_mcast) in archive vmlinux.a >>> referenced by icssg_prueth.c:1812 (drivers/net/ethernet/ti/icssg/icssg_prueth.c:1812) >>> drivers/net/ethernet/ti/icssg/icssg_prueth.o:(prueth_netdevice_event) in archive vmlinux.a ld.lld: error: undefined symbol: hsr_get_port_ndev >>> referenced by icssg_prueth.c:712 (drivers/net/ethernet/ti/icssg/icssg_prueth.c:712) >>> drivers/net/ethernet/ti/icssg/icssg_prueth.o:(icssg_prueth_hsr_del_mcast) in archive vmlinux.a >>> referenced by icssg_prueth.c:712 (drivers/net/ethernet/ti/icssg/icssg_prueth.c:712) >>> drivers/net/etherneteth_hsr_del_mcast) in archive vmlinux.a >>> referenced by icssg_prueth.c:683 (drivers/net/ethernet/ti/icssg/icssg_prueth.c:683) >>> drivers/net/ethernet/ti/icssg/icssg_prueth.o:(icssg_prueth_hsr_add_mcast) in archive vmlinux.a >>> referenced 1 more times Fixes: 95540ad6747c ("net: ti: icssg-prueth: Add support for HSR frame forward offload") Signed-off-by: Kevin Hao Cc: stable@vger.kernel.org Link: https://patch.msgid.link/20260207-icssg-dep-v3-1-8c47c1937f81@gmail.com Signed-off-by: Paolo Abeni Signed-off-by: Sasha Levin

net: ti: icssm-prueth: Adds ICSSM Ethernet driver

2025-09-14T20:00:54Z

Updates Kernel configuration to enable PRUETH driver and its dependencies along with makefile changes to add the new PRUETH driver. Changes includes init and deinit of ICSSM PRU Ethernet driver including net dev registration and firmware loading for DUAL-MAC mode running on PRU-ICSS2 instance. Changes also includes link handling, PRU booting, default firmware loading and PRU stopping using existing remoteproc driver APIs.

net: ti: icssg-prueth: Use page_pool API for RX buffer allocation

2025-03-11T10:09:55Z

This 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 granularity so we are not efficient in memory usage. i.e. we are using PAGE_SIZE (4KB) memory for 1.5KB max packet size.

net: ti: icssg-prueth: Add support for ICSSG switch firmware

2024-05-30T13:37:26Z

Add support for ICSSG switch firmware using existing Dual EMAC driver with switchdev. Limitations: VLAN offloading is limited to 0-256 IDs. MDB/FDB static entries are limited to 511 entries and different FDBs can hash to same bucket and thus may not completely offloaded Example assuming ETH1 and ETH2 as ICSSG2 interfaces: Switch to ICSSG Switch mode: ip link add name br0 type bridge ip link set dev eth1 master br0 ip link set dev eth2 master br0 ip link set dev br0 up bridge vlan add dev br0 vid 1 pvid untagged self Going back to Dual EMAC mode: ip link set dev br0 down ip link set dev eth1 nomaster ip link set dev eth2 nomaster ip link del name br0 type bridge By default, Dual EMAC firmware is loaded, and can be changed to switch mode by above steps Reviewed-by: Andrew Lunn Signed-off-by: MD Danish Anwar Signed-off-by: Paolo Abeni

net: ti: icssg-prueth: Add ICSSG Ethernet driver for AM65x SR1.0 platforms

2024-04-09T07:47:29Z

Add the PRUeth driver for the ICSSG subsystem found in AM65x SR1.0 devices. The main differences that set SR1.0 and SR2.0 apart are the missing TXPRU core in SR1.0, two extra DMA channels for management purposes and different firmware that needs to be configured accordingly. Based on the work of Roger Quadros, Vignesh Raghavendra and Grygorii Strashko in TI's 5.10 SDK [1].

net: handle HAS_IOPORT dependencies

2024-04-08T10:56:56Z

In a future patch HAS_IOPORT=n will disable inb()/outb() and friends at compile time. We thus need to add HAS_IOPORT as dependency for those drivers requiring them. For the DEFXX driver the use of I/O ports is optional and we only need to fence specific code paths. It also turns out that with HAS_IOPORT handled explicitly HAMRADIO does not need the !S390 dependency and successfully builds the bpqether driver.
