* | net: dsa: microchip: properly support platform_data probingVladimir Oltean2023-12-071-8/+13
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The ksz driver has bits and pieces of platform_data probing support, but it doesn't work. The conventional thing to do is to have an encapsulating structure for struct dsa_chip_data that gets put into dev->platform_data. This driver expects a struct ksz_platform_data, but that doesn't contain a struct dsa_chip_data as first element, which will obviously not work with dsa_switch_probe() -> dsa_switch_parse(). Pointing dev->platform_data to a struct dsa_chip_data directly is in principle possible, but that doesn't work either. The driver has ksz_switch_detect() to read the device ID from hardware, followed by ksz_check_device_id() to compare it against a predetermined expected value. This protects against early errors in the SPI/I2C communication. With platform_data, the mechanism in ksz_check_device_id() doesn't work and even leads to NULL pointer dereferences, since of_device_get_match_data() doesn't work in that probe path. So obviously, the platform_data support is actually missing, and the existing handling of struct ksz_platform_data is bogus. Complete the support by adding a struct dsa_chip_data as first element, and fixing up ksz_check_device_id() to pick up the platform_data instead of the unavailable of_device_get_match_data(). The early dev->chip_id assignment from ksz_switch_register() is also bogus, because ksz_switch_detect() sets it to an initial value. So remove it. Also, ksz_platform_data :: enabled_ports isn't used anywhere, delete it.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch introduces the function 'ksz8_phy_port_link_up' to the Microchip KSZ8xxx driver. This function is responsible for setting up flow control and duplex settings for the ports that are integrated with PHYs. The KSZ8795 switch supports asymmetric pause control, which can't be fully utilized since a single bit controls both RX and TX pause. Despite this, the flow control can be adjusted based on the auto-negotiation process, taking into account the capabilities of both link partners. On the other hand, the KSZ8873's PORT_FORCE_FLOW_CTRL bit can be set by the hardware bootstrap, which ignores the auto-negotiation result. Therefore, even in auto-negotiation mode, we need to ensure that this bit is correctly set. When auto-negotiation isn't in use, we enforce symmetric pause control for the KSZ8795 switch. Please note, forcing flow control disable on a port while still advertising pause support isn't possible. While this scenario might not be practical or desired, it's important to be aware of this limitation when working with the KSZ8873 and similar devices.

Hence, the HSR core code shall be used to discard those not caught frames. Moreover, some switch registers adjustments are required - like setting MAC address of HSR network interface. Additionally, the KSZ9477 switch has been configured to forward frames between HSR ports (e.g. 1,2) members to provide support for NETIF_F_HW_HSR_FWD flag. Join and leave functions are written in a way, that are executed with single port - i.e. configuration is NOT done only when second HSR port is configured.

ACLs enable filtering of incoming layer 2 MAC, layer 3 IP, and layer 4 TCP/UDP packets on each port. They provide additional capabilities for filtering routed network protocols and can take precedence over other forwarding functions. ACLs can filter ingress traffic based on header fields such as source/destination MAC address, EtherType, IPv4 address, IPv4 protocol, UDP/TCP ports, and TCP flags. The ACL is an ordered list of up to 16 access control rules programmed into the ACL Table. Each entry specifies a set of matching conditions and action rules for controlling packet forwarding and priority. The ACL also implements a count function, generating an interrupt instead of a forwarding action. It can be used as a watchdog timer or an event counter. The ACL consists of three parts: matching rules, action rules, and processing entries. Multiple match conditions can be either AND'ed or OR'ed together. This patch introduces support for a subset of the available ACL functionality, specifically layer 2 matching and prioritization of matched packets. For example: tc qdisc add dev lan2 clsact tc filter add dev lan2 ingress protocol 0x88f7 flower action skbedit prio 7 tc qdisc add dev lan1 clsact tc filter add dev lan1 ingress protocol 0x88f7 flower action skbedit prio 7 The hardware offloading implementation was benchmarked against a configuration without hardware offloading. This latter setup relied on a software-based Linux bridge. No noticeable differences were observed between the two configurations. Here is an example of software-based test: ip l s dev enu1u1 up ip l s dev enu1u2 up ip l s dev enu1u4 up ethtool -A enu1u1 autoneg off rx off tx off ethtool -A enu1u2 autoneg off rx off tx off ethtool -A enu1u4 autoneg off rx off tx off ip l a name br0 type bridge ip l s dev br0 up ip l s enu1u1 master br0 ip l s enu1u2 master br0 ip l s enu1u4 master br0 tc qdisc add dev enu1u1 root handle 1: ets strict 4 priomap 3 3 2 2 1 1 0 0 tc qdisc add dev enu1u4 root handle 1: ets strict 4 priomap 3 3 2 2 1 1 0 0 tc qdisc add dev enu1u2 root handle 1: ets strict 4 priomap 3 3 2 2 1 1 0 0 tc qdisc add dev enu1u1 clsact tc filter add dev enu1u1 ingress protocol ipv4 flower action skbedit prio 7 tc qdisc add dev enu1u4 clsact tc filter add dev enu1u4 ingress protocol ipv4 flower action skbedit prio 0 On a system attached to the port enu1u2 I run two iperf3 server instances: iperf3 -s -p 5210 & iperf3 -s -p 5211 & On systems attached to enu1u4 and enu1u1 I run: iperf3 -u -c 172.17.0.1 -p 5210 -b100M -l1472 -t100 and iperf3 -u -c 172.17.0.1 -p 5211 -b100M -l1472 -t100 As a result, IP traffic on port enu1u1 will be prioritized and take precedence over IP traffic on port enu1u4 Signed-off-by: Oleksij Rempel <[email protected]> Reviewed-by: Vladimir Oltean <[email protected]> Signed-off-by: David S.

Moreover, the in-register disablement of MMD_DEVICE_ID_EEE_ADV.MMD_EEE_ADV MMD register is removed, as this code is both; now executed too late (after previous rework of the PHY and DSA for KSZ switches) and not required as setting all members of eee_broken_modes bit field prevents the KSZ9477 from advertising EEE.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The commit (SHA1: 5c844d57aa7894154e49cf2fc648bfe2f1aefc1c) provided code to apply "Module 6: Certain PHY registers must be written as pairs instead of singly" errata for KSZ9477 as this chip for certain PHY registers (0xN120 to 0xN13F, N=1,2,3,4,5) must be accesses as 32 bit words instead of 16 or 8 bit access. Otherwise, adjacent registers (no matter if reserved or not) are overwritten with 0x0. Without this patch some registers (e.g. 0x113c or 0x1134) required for 32 bit access are out of valid regmap ranges. As a result, following error is observed and KSZ9477 is not properly configured: ksz-switch spi1.0: can't rmw 32bit reg 0x113c: -EIO ksz-switch spi1.0: can't rmw 32bit reg 0x1134: -EIO ksz-switch spi1.0 lan1 (uninitialized): failed to connect to PHY: -EIO ksz-switch spi1.0 lan1 (uninitialized): error -5 setting up PHY for tree 0, switch 0, port 0 The solution is to modify regmap_reg_range to allow accesses with 4 bytes boundaries.

Some of the new KSZ8795 register information are wrong compared to previous code. KSZ8795 also behaves differently in that the STATIC_MAC_TABLE_USE_FID and STATIC_MAC_TABLE_FID bits are off by 1 when doing MAC table reading than writing. To compensate that a special code was added to shift the register value by 1 before applying those bits. This is wrong when the code is running on KSZ8863, so this special code is only executed when KSZ8795 is detected.

The trouble is that, when compared to ksz_write8(), ksz_pwrite8() also adjusts the register offset with the port base address. So in reality, ksz_pwrite8(offset=0x56) accesses register 0x56 + 0x50 = 0xa6, which in this switch appears to be unmapped, and the RGMII delay configuration on the CPU port does nothing. So if the switch wasn't fine with the RGMII delay configuration done through pin strapping and relied on Linux to apply a different one in order to pass traffic, this is now broken. Using the offset translation logic imposed by ksz_pwrite8(), the correct value for regs[P_XMII_CTRL_1] should have been 0x6 on ksz8795_regs[], in order to really end up accessing register 0x56. Static code analysis shows that, despite there being multiple other accesses to regs[P_XMII_CTRL_1] in this driver, the only code path that is applicable to ksz8795_regs[] and ksz8_dev_ops is ksz_set_xmii(). Therefore, the problem is isolated to RGMII delays. In its current form, ksz8795_regs[] contains the same value for P_XMII_CTRL_0 and for P_XMII_CTRL_1, and this raises valid suspicions that writes made by the driver to regs[P_XMII_CTRL_0] might overwrite writes made to regs[P_XMII_CTRL_1] or vice versa. Again, static analysis shows that the only accesses to P_XMII_CTRL_0 from the driver are made from code paths which are not reachable with ksz8_dev_ops. So the accesses made by ksz_set_xmii() are safe for this switch family.
