Christian Marangi says: ==================== leds: trigger: netdev: add additional modes This is a continue of [1]. It was decided to take a more gradual approach to implement LEDs support for switch and phy starting with basic support and then implementing the hw control part when we have all the prereq done. This should be the final part for the netdev trigger. I added net-next tag and added netdev mailing list since I was informed that this should be merged with netdev branch. We collect some info around and we found a good set of modes that are common in almost all the PHY and Switch. These modes are: - Modes for dedicated link speed(10, 100, 1000 mbps). Additional mode can be added later following this example. - Modes for half and full duplex. The original idea was to add hw control only modes. While the concept makes sense in practice it would results in lots of additional code and extra check to make sure we are setting correct modes. With the suggestion from Andrew it was pointed out that using the ethtool APIs we can actually get the current link speed and duplex and this effectively removed the problem of having hw control only modes since we can fallback to software. Since these modes are supported by software, we can skip providing an user for this in the LED driver to support hw control for these new modes (that will come right after this is merged) and prevent this to be another multi subsystem series. For link speed and duplex we use ethtool APIs. To call ethtool APIs, rtnl lock is needed but this can be skipped on handling netdev events as the lock is already held.

Add additional modes for specific link duplex. Use ethtool APIs to get the current link duplex and enable the LED accordingly. Under netdev event handler the rtnl lock is already held and is not needed to be set to access ethtool APIs. This is especially useful for PHY and Switch that supports LEDs hw control for specific link duplex. Add additional modes: - half_duplex: Turn on LED when link is half duplex - full_duplex: Turn on LED when link is full duplex Signed-off-by:

Under netdev event handler the rtnl lock is already held and is not needed to be set to access ethtool APIs. This is especially useful for PHY and Switch that supports LEDs hw control for specific link speed. (example scenario a PHY that have 2 LED connected one green and one orange where the green is turned on with 1000mbps speed and orange is turned on with 10mpbs speed) On mode set from sysfs we check if we have enabled split link speed mode and reject enabling generic link mode to prevent wrong and redundant configuration. Rework logic on the set baseline state to support these new modes to select if we need to turn on or off the LED. Add additional modes: - link_10: Turn on LED when link speed is 10mbps - link_100: Turn on LED when link speed is 100mbps - link_1000: Turn on LED when link speed is 1000mbps Signed-off-by:

Petr Machata says: ==================== selftests: Preparations for out-of-order-operations patches in mlxsw The mlxsw driver currently makes the assumption that the user applies configuration in a bottom-up manner. Thus netdevices need to be added to the bridge before IP addresses are configured on that bridge or SVI added on top of it. Enslaving a netdevice to another netdevice that already has uppers is in fact forbidden by mlxsw for this reason. Despite this safety, it is rather easy to get into situations where the offloaded configuration is just plain wrong. Over the course of the following several patchsets, mlxsw code is going to be adjusted to diminish the space of wrongly offloaded configurations. Ideally the offload state will reflect the actual state, regardless of the sequence of operation used to construct that state. Several selftests build configurations that will not be offloadable in the future on some systems. The reason is that what will get offloaded is the actual configuration, not the configuration steps. For example, when a port is added to a bridge that has an IP address, that bridge will get a RIF, which it would not have with the current code. But on Nvidia Spectrum-1 machines, MAC addresses of all RIFs need to have the same prefix, which the bridge will violate. The RIF thus couldn't be created, and the enslavement is therefore canceled, because it would lead to an unoffloadable configuration. This breaks some selftests. In this patchset, adjust selftests to avoid the configurations that mlxsw would be incapable of offloading, while maintaining relevance with regards to the feature that is being tested. There are generally two cases of fixes: - Disabling IPv6 autogen on bridges that do not participate in routing, either because of the abovementioned requirement to keep the same MAC prefix on all in-HW router interfaces, or, on 802.1ad bridges, because in-HW router interfaces are not supported at all. - Setting the bridge MAC address to what it will become after the first member port is attached, so that the in-HW router interface is created with a supported MAC address. The patchset is then split thus: - Patches #1-#7 adjust generic selftests - Patches #8-#16 adjust mlxsw-specific selftests ==================== Link: https://lore.kernel.org/r/cover.1687265905.git.petrm@nvidia.comSigned-off-by:

In a future patch, mlxsw will start adding RIFs to uppers of front panel port netdevices, if they have an IP address. At the time that the front panel port is enslaved to the bridge, the bridge MAC address does not have the same prefix as other interfaces in the system. On Nvidia Spectrum-1 machines all the RIFs have to have the same 38-bit MAC address prefix. Since the bridge does not obey this limitation, the RIF cannot be created, and the enslavement attempt is vetoed on the grounds of the configuration not being offloadable. The bridge eventually inherits MAC address from its first member, after the enslavement is acked. A number of (mainly VXLAN) selftests already work around the problem by setting the MAC address to whatever it will eventually be anyway. Do the same for this selftest. Signed-off-by:

Currently for each timestamp frame, the SW needs to go and read the received timestamp over the MDIO bus. But the HW has the capability to store the received nanoseconds part and the least significant two bits of the seconds in the reserved field of the PTP header. In this way we could save few MDIO transactions (actually a little more transactions because the access to the PTP registers are indirect) for each received frame. Instead of reading the rest of seconds part of the timestamp of the frame using MDIO transactions schedule PTP worker thread to read the seconds part every 500ms and then for each of the received frames use this information. Because if for example running with 512 frames per second, there is no point to read 512 times the second part. Doing all these changes will give a great CPU usage performance. Running ptp4l with logSyncInterval of -9 will give a ~60% CPU improvement. Signed-off-by:
