Andrew Lunn says: ==================== Unique mv88e6xxx IRQ names There are a few boards which have multiple mv88e6xxx switches. With such boards, it can be hard to determine which interrupts belong to which switches. Make the interrupt names unique by including the device name in the interrupt name. For the SERDES interrupt, also include the port number. As a result of these patches ZII devel C looks like: 50: 0 gpio-vf610 27 Level mv88e6xxx-0.1:00 54: 0 mv88e6xxx-g1 3 Edge mv88e6xxx-0.1:00-g1-atu-prob 56: 0 mv88e6xxx-g1 5 Edge mv88e6xxx-0.1:00-g1-vtu-prob 58: 0 mv88e6xxx-g1 7 Edge mv88e6xxx-0.1:00-g2 61: 0 mv88e6xxx-g2 1 Edge !mdio-mux!mdio@1!switch@0!mdio:01 62: 0 mv88e6xxx-g2 2 Edge !mdio-mux!mdio@1!switch@0!mdio:02 63: 0 mv88e6xxx-g2 3 Edge !mdio-mux!mdio@1!switch@0!mdio:03 64: 0 mv88e6xxx-g2 4 Edge !mdio-mux!mdio@1!switch@0!mdio:04 70: 0 mv88e6xxx-g2 10 Edge mv88e6xxx-0.1:00-serdes-10 75: 0 mv88e6xxx-g2 15 Edge mv88e6xxx-0.1:00-watchdog 76: 5 gpio-vf610 26 Level mv88e6xxx-0.2:00 80: 0 mv88e6xxx-g1 3 Edge mv88e6xxx-0.2:00-g1-atu-prob 82: 0 mv88e6xxx-g1 5 Edge mv88e6xxx-0.2:00-g1-vtu-prob 84: 4 mv88e6xxx-g1 7 Edge mv88e6xxx-0.2:00-g2 87: 2 mv88e6xxx-g2 1 Edge !mdio-mux!mdio@2!switch@0!mdio:01 88: 0 mv88e6xxx-g2 2 Edge !mdio-mux!mdio@2!switch@0!mdio:02 89: 0 mv88e6xxx-g2 3 Edge !mdio-mux!mdio@2!switch@0!mdio:03 90: 0 mv88e6xxx-g2 4 Edge !mdio-mux!mdio@2!switch@0!mdio:04 95: 3 mv88e6xxx-g2 9 Edge mv88e6xxx-0.2:00-serdes-9 96: 0 mv88e6xxx-g2 10 Edge mv88e6xxx-0.2:00-serdes-10 101: 0 mv88e6xxx-g2 15 Edge mv88e6xxx-0.2:00-watchdog Interrupt names like !mdio-mux!mdio@2!switch@0!mdio:01 are created by phylib for the integrated PHYs.

Michal Kubecek says: ==================== ethtool: allow nesting of begin() and complete() callbacks The ethtool ioctl interface used to guarantee that ethtool_ops callbacks were always called in a block between calls to ->begin() and ->complete() (if these are defined) and that this whole block was executed with RTNL lock held: rtnl_lock(); ops->begin(); /* other ethtool_ops calls */ ops->complete(); rtnl_unlock(); This prevented any nesting or crossing of the begin-complete blocks. However, this is no longer guaranteed even for ioctl interface as at least ethtool_phys_id() releases RTNL lock while waiting for a timer. With the introduction of netlink ethtool interface, the begin-complete pairs are naturally nested e.g. when a request triggers a netlink notification. Fortunately, only minority of networking drivers implements begin() and complete() callbacks and most of those that do, fall into three groups: - wrappers for pm_runtime_get_sync() and pm_runtime_put() - wrappers for clk_prepare_enable() and clk_disable_unprepare() - begin() checks netif_running() (fails if false), no complete() First two have their own refcounting, third is safe w.r.t. nesting of the blocks. Only three in-tree networking drivers need an update to deal with nesting of begin() and complete() calls: via-velocity and epic100 perform resume and suspend on their own and wil6210 completely serializes the calls using its own mutex (which would lead to a deadlock if a request request triggered a netlink notification).

Unlike most networking drivers using begin() and complete() ethtool_ops callbacks to resume a device which is down and suspend it again when done, epic100 does not use standard refcounted infrastructure but sets device sleep state directly. With the introduction of netlink ethtool interface, we may have nested begin-complete blocks so that inner complete() would put the device back to sleep for the rest of the outer block. To avoid rewriting an old and not very actively developed driver, just add a nesting counter and only perform resume and suspend on the outermost level. Signed-off-by:

The wil6210 driver locks a mutex in begin() ethtool_ops callback and unlocks it in complete() so that all ethtool requests are serialized. This is not going to work correctly with netlink interface; e.g. when ioctl triggers a netlink notification, netlink code would call begin() again while the mutex taken by ioctl code is still held by the same task. Let's get rid of the begin() and complete() callbacks and move the mutex locking into the remaining ethtool_ops handlers except get_drvinfo which only copies strings that are not changing so that there is no need for serialization.

The recent MD5 tests added duplicate configuration in the default VRF. This change exposed a bug in existing tests designed to verify no connection when client and server are not in the same domain. The server should be running bound to the vrf device with the client run in the default VRF (the -2 option is meant for validating connection data). Fix the option for both tests. While technically this is a bug in previous releases, the tests are properly failing since the default VRF does not have any routing configuration so there really is no need to backport to prior releases.

In hclge_inform_reset_assert_to_vf(), variable reset_type(enum type) will be copied into msg_data whose size is 2 bytes. Currently, hip08 is a little-endian machine, so the lower two bytes of reset_type will be copied to msg_data. But when running on a big-endian machine, msg_data will have a wrong value(the higher two bytes of reset_type). So this patch modifies the type of reset_type to u16, and adds a build check in case enum hnae3_reset_type has value larger than U16_MAX. Signed-off-by:

Vladimir Oltean says: ==================== Convert Felix DSA switch to PHYLINK Unlike most other conversions, this one is not by far a trivial one, and should be seen as "Layerscape PCS meets PHYLINK". Actually, the PCS doesn't need a lot of hand-holding and most of our other devices 'just work' (this one included) without any sort of operating system awareness, just an initialization procedure done typically in the bootloader. Our issues start when the PCS stops from "just working", and that is where PHYLINK comes in handy. The PCS is not specific to the Vitesse / Microsemi / Microchip switching core at all. Variations of this SerDes/PCS design can also be found on DPAA1 and DPAA2 hardware. The main idea of the abstraction provided is that the PCS looks so much like a PHY device, that we model it as an actual PHY device and run the generic PHY functions on it, where appropriate. The 4xSGMII, QSGMII and QSXGMII modes are fairly straightforward. The SerDes protocol which the driver calls 2500Base-X mode (a misnomer) is more interesting. There is a description of how it works and what can be done with it in patch 9/9 (in a comment above vsc9959_pcs_init_2500basex). In short, it is a fixed speed protocol with no auto-negotiation whatsoever. From my research of the SGMII-2500 patent [1], it has nothing to do with SGMII-2500. That one: * does not define any change to the AN base page compared to plain 10/100/1000 SGMII. This implies that the 2500 speed is not negotiable, but the other speeds are. In our case, when the SerDes is configured for this protocol it's configured for good, there's no going back to SGMII. * runs at a higher base frequency than regular SGMII. So SGMII-2500 operating at 1000 Mbps wouldn't interoperate with plain SGMII at 1000 Mbps. Strange, but ok.. * Emulates lower link speeds than 2500 by duplicating the codewords twice, then thrice, then twice again etc (2.5/25/250 times on average). The Layerscape PCS doesn't do that (it is fixed at 2500 Mbaud). But on the other hand it isn't completely compatible with Base-X either, since it doesn't do 802.3z / clause 37 auto negotiation (flow control, local/remote fault etc). It is compatible with 2500Base-X without in-band AN, and that is exactly how we decided to expose it (this is actually similar to what others do). For SGMII and USXGMII, the driver is using the PHYLINK 'managed = "in-band-status"' DTS binding to figure out whether in-band AN is expected to be enabled in the PCS or not. It is expected that the attached PHY follows suite, but there is a gap here: the PHY driver does not react to this setting, so only one of "AN on" and "AN off" works on any particular PHY, even though that PHY might support bypassing the SGMII AN process, as is the case on the VSC8514 PHY present on the LS1028A-RDB board. A separate series will be sent to propose a way to deal with that. I dropped the Ocelot PHYLINK conversion because: * I don't have VSC7514 hardware anyway * The hardware is so different in this regard that there's almost nothing to share anyway. Changes in v5: - Added the register write to DEV_CLOCK_CFG back in felix_phylink_mac_config in patch 9/9. Changes in v4: - This is mostly a resend of v3, with the only notable change that I've dropped the PHY core patches for in_band_autoneg and I'll propose them independently. v1 series: https://www.spinics.net/lists/netdev/msg613869.html RFC v2 series: https://www.spinics.net/lists/netdev/msg620128.html v3 series: https://www.spinics.net/lists/netdev/msg622060.html v4 series: https://www.spinics.net/lists/netdev/msg622606.html [0]: https://www.spinics.net/lists/netdev/msg613869.html [1]: https://patents.google.com/patent/US7356047B1/en ==================== Signed-off-by:

Layerscape SoCs traditionally expose the SerDes configuration/status for Ethernet protocols (PCS for SGMII/USXGMII/10GBase-R etc etc) in a register format that is compatible with clause 22 or clause 45 (depending on SerDes protocol). Each MAC has its own internal MDIO bus on which there is one or more of these PCS's, responding to commands at a configurable PHY address. The per-port internal MDIO bus (which is just for PCSs) is totally separate and has nothing to do with the dedicated external MDIO controller (which is just for PHYs), but the register map for the MDIO controller is the same. The VSC9959 (Felix) switch instantiated in the LS1028A is integrated in hardware with the ENETC PCS of its DSA master, and reuses its MDIO controller driver, so Felix has been made to depend on it in Kconfig. +------------------------------------------------------------------------+ | +--------+ GMII (typically disabled via RCW) | | ENETC PCI | ENETC |--------------------------+ | | Root Complex | port 3 |-----------------------+ | | | Integrated +--------+ | | | | Endpoint | | | | +--------+ 2.5G GMII | | | | | ENETC |--------------+ | | | | | port 2 |-----------+ | | | | | +--------+ | | | | | | +--------+ +--------+ | | | Felix | | Felix | | | | port 4 | | port 5 | | | +--------+ +--------+ | | | | +--------+ +--------+ +--------+ +--------+ +--------+ +--------+ | | | ENETC | | ENETC | | Felix | | Felix | | Felix | | Felix | | | | port 0 | | port 1 | | port 0 | | port 1 | | port 2 | | port 3 | | +------------------------------------------------------------------------+ | |||| SerDes | |||| |||| |||| |||| | | +--------+block | +--------------------------------------------+ | | | ENETC | | | ENETC port 2 internal MDIO bus | | | | port 0 | | | PCS PCS PCS PCS | | | | PCS | | | 0 1 2 3 | | +-----------------|------------------------------------------------------+ v v v v v v SGMII/ RGMII QSGMII/QSXGMII/4xSGMII/4x1000Base-X/4x2500Base-X USXGMII/ (bypasses 1000Base-X/ SerDes) 2500Base-X In the LS1028A SoC described above, the VSC9959 Felix switch is PF5 of the ENETC root complex, and has 2 BARs: - BAR 4: the switch's effective registers - BAR 0: the MDIO controller register map lended from ENETC port 2 (PF2), for accessing its associated PCS's. This explanation is necessary because the patch does some renaming "pci_bar" -> "switch_pci_bar" for clarity, which would otherwise appear a bit obtuse. The fact that the internal MDIO bus is "borrowed" is relevant because the register map is found in PF5 (the switch) but it triggers an access fault if PF2 (the ENETC DSA master) is not enabled. This is not treated in any way (and I don't think it can be treated). All of this is so SoC-specific, that it was contained as much as possible in the platform-integration file felix_vsc9959.c. We need to parse and pre-validate the device tree because of 2 reasons: - The PHY mode (SerDes protocol) cannot change at runtime due to SoC design. - There is a circular dependency in that we need to know what clause the PCS speaks in order to find it on the internal MDIO bus. But the clause of the PCS depends on what phy-mode it is configured for. The goal of this patch is to make steps towards removing the bootloader dependency for SGMII PCS pre-configuration, as well as to add support for monitoring the in-band SGMII AN between the PCS and the system-side link partner (PHY or other MAC). In practice the bootloader dependency is not completely removed. U-Boot pre-programs the PHY address at which each PCS can be found on the internal MDIO bus (MDEV_PORT). This is needed because the PCS of each port has the same out-of-reset PHY address of zero. The SerDes register for changing MDEV_PORT is pretty deep in the SoC (outside the addresses of the ENETC PCI BARs) and therefore inaccessible to us from here. Felix VSC9959 and Ocelot VSC7514 are integrated very differently in their respective SoCs, and for that reason Felix does not use the Ocelot core library for PHYLINK. On one hand we don't want to impose the fixed phy-mode limitation to Ocelot, and on the other hand Felix doesn't need to force the MAC link speed the way Ocelot does, since the MAC is connected to the PCS through a fixed GMII, and the PCS is the one who does the rate adaptation at lower link speeds, which the MAC does not even need to know about. In fact changing the GMII speed for Felix irrecoverably breaks transmission through that port until a reset. The pair with ENETC port 3 and Felix port 5 is optional and doesn't support tagging. When we enable it, swp5 is a regular slave port, albeit an internal one. The trouble is that it doesn't work, and that is because the DSA PHYLIB adaptation layer doesn't treat fixed-link slave ports. So that is yet another reason for wanting to convert Felix to the native PHYLINK API. Signed-off-by:Vladimir Oltean <vladimir.oltean@nxp.com> Signed-off-by:

The Ocelot switchdev driver and the Felix DSA one need it for different reasons. Felix (or at least the VSC9959 instantiation in NXP LS1028A) is integrated with the traditional NXP Layerscape PCS design which does not support runtime configuration of SerDes protocol. So it needs to pre-validate the phy-mode from the device tree and prevent PHYLINK from attempting to change it. For this, it needs to cache it in a private variable. Signed-off-by:

This increases the MDIO hold time to 5 enet_clk cycles from the previous value of 0. This is actually the out-of-reset value, that the driver was previously overwriting with 0.

Within the LS1028A SoC, the register map for the ENETC MDIO controller is instantiated a few times: for the central (external) MDIO controller, for the internal bus of each standalone ENETC port, and for the internal bus of the Felix switch. Refactoring is needed to support multiple MDIO buses from multiple drivers. The enetc_hw structure is made an opaque type and a smaller enetc_mdio_priv is created. 'mdio_base' - MDIO registers base address - is being parameterized, to be able to work with different MDIO register bases. The ENETC MDIO bus operations are exported from the fsl-enetc-mdio kernel object, the same that registers the central MDIO controller (the dedicated PF). The ENETC main driver has been changed to select it, and use its exported helpers to further register its private MDIO bus. The DSA Felix driver will do the same. Signed-off-by:

The DSA drivers that implement .phylink_mac_link_state should normally register an interrupt for the PCS, from which they should call phylink_mac_change(). However not all switches implement this, and those who don't should set this flag in dsa_switch in the .setup callback, so that PHYLINK will poll for a few ms until the in-band AN link timer expires and the PCS state settles.

Some MAC PCS blocks are unable to provide interrupts when their status changes. As we already have support in phylink for polling status, use this to provide a hook for MACs to enable polling mode. The patch idea was picked up from Russell King's suggestion on the macb phylink patch thread here [0] but the implementation was changed. Instead of introducing a new phylink_start_poll() function, which would make the implementation cumbersome for common PHYLINK implementations for multiple types of devices, like DSA, just add a boolean property to the phylink_config structure, which is just as backwards-compatible. https://lkml.org/lkml/2019/12/16/603Suggested-by:

QSGMII is a SerDes protocol clocked at 5 Gbaud (4 times higher than SGMII which is clocked at 1.25 Gbaud), with the same 8b/10b encoding and some extra symbols for synchronization. Logically it offers 4 SGMII interfaces multiplexed onto the same physical lanes. Each MAC PCS has its own in-band AN process with the system side of the QSGMII PHY, which is identical to the regular SGMII AN process. So allow QSGMII as a valid in-band AN mode, since it is no different from software perspective from regular SGMII. Signed-off-by:
