Dejin Zheng says: ==================== introduce read_poll_timeout This patch sets is introduce read_poll_timeout macro, it is an extension of readx_poll_timeout macro. the accessor function op just supports only one parameter in the readx_poll_timeout macro, but this macro can supports multiple variable parameters for it. so functions like phy_read(struct phy_device *phydev, u32 regnum) and phy_read_mmd(struct phy_device *phydev, int devad, u32 regnum) can use this poll timeout framework. the first patch introduce read_poll_timeout macro, and the second patch redefined readx_poll_timeout macro by read_poll_timeout(), and the other patches are examples using read_poll_timeout macro. v6 -> v7: - add a parameter to supports that it can sleep some time before read operation in read_poll_timeout macro. - add prefix with double underscores for some variable to avoid any variable re-declaration or shadowing in patch 3 and patch 7. v5 -> v6: - add some check to keep the code more similar in patch 8 v4 -> v5: - add some msleep() before call phy_read_mmd_poll_timeout() to keep the code more similar in patch 6 and patch 9. - add a patch of drop by v4, it can add msleep before call phy_read_poll_timeout() to keep the code more similar. v3 -> v4: - add 3 examples of using new functions. - deal with precedence issues for parameter cond. - drop a patch about phy_poll_reset() function. v2 -> v3: - modify the parameter order of newly added functions. phy_read_mmd_poll_timeout(val, cond, sleep_us, timeout_us, \ phydev, devaddr, regnum) || \/ phy_read_mmd_poll_timeout(phydev, devaddr regnum, val, cond, \ sleep_us, timeout_us) phy_read_poll_timeout(val, cond, sleep_us, timeout_us, \ phydev, regnum) || \/ phy_read_poll_timeout(phydev, regnum, val, cond, sleep_us, \ timeout_us) v1 -> v2: - passed a phydev, device address and a reg to replace args... parameter in phy_read_mmd_poll_timeout() by Andrew Lunn 's suggestion in patch 3. Andrew Lunn <andrew@lunn.ch>, Thanks very much for your help! - also in patch 3, handle phy_read_mmd return an error(the return value < 0) in phy_read_mmd_poll_timeout(). Thanks Andrew again. - in patch 6, pass a phydev and a reg to replace args... parameter in phy_read_poll_timeout(), and also handle the phy_read() function's return error. ==================== Signed-off-by:David S.

Ido Schimmel says: ==================== devlink: Preparations for trap policers support This patch set prepares the code for devlink-trap policer support in a follow-up patch set [1][2]. No functional changes intended. Policers are going to be added as attributes of packet trap groups, which are entities used to aggregate logically related packet traps. This will allow users, for example, to limit all the packets that encountered an exception during routing to 10Kpps. However, currently, device drivers register their packet trap groups implicitly when they register their packet traps via devlink_traps_register(). This makes it difficult to pass additional attributes for the groups. For example, the policer bound to the group. Therefore, this patch set converts device drivers to explicitly register their packet trap groups. This will later allow these drivers to register the group with additional attributes, if any. ==================== Acked-by:

Packet trap groups are now explicitly registered by drivers and not implicitly registered when the packet traps are registered. Therefore, there is no need to encode entire group structure the trap is associated with inside the trap structure. Instead, only pass the group identifier. Refer to it as initial group identifier, as future patches will allow user space to move traps between groups. Signed-off-by:

Currently, packet trap groups are implicitly registered by drivers upon packet trap registration. When the traps are registered, each is associated with a group and the group is created by devlink, if it does not exist already. This makes it difficult for drivers to pass additional attributes for the groups. Therefore, as a preparation for future patches that require passing additional group attributes, add an API to explicitly register / unregister these groups. Next patches will convert existing drivers to use this API. Signed-off-by:

So far only the reset bit it set, but the handler executing the reset is not scheduled. Therefore nothing will happen until some other action schedules the handler. Improve this by ensuring that the handler is scheduled. Signed-off-by:

The current implementation makes the implicit assumption that if a bit is set, then the work is scheduled already. Remove the need for this implicit assumption and call schedule_work() always. It will check internally whether the work is scheduled already. Signed-off-by:

Jeff Kirsher says: ==================== 100GbE Intel Wired LAN Driver Updates 2020-03-21 Implement basic support for the devlink interface in the ice driver. Additionally pave some necessary changes for adding a devlink region that exposes the NVM contents. This series first contains 5 patches for enabling and implementing full NVM read access via the ETHTOOL_GEEPROM interface. This includes some cleanup of endian-types, a new function for reading from the NVM and Shadow RAM as a flat addressable space, a function to calculate the available flash size during load, and a change to how some of the NVM version fields are stored in the ice_nvm_info structure. Following this is 3 patches for implementing devlink support. First, one patch which implements the basic framework and introduces the ice_devlink.c file. Second, a patch to implement basic .info_get support. Finally, a patch which reads the device PBA identifier and reports it as the `board.id` value in the .info_get response. ==================== Signed-off-by: -

With MTU sized receive buffers it is not expected to have CQE_RX with multiple receive buffer pointers. But since same physcial link is shared by PF and it's VFs, the max receive packet configured at link could be morethan MTU. Hence there is a chance of receiving plts morethan MTU which then gets DMA'ed into multiple buffers and notified in a single CQE_RX. This patch treats such pkts as errors and frees up receive buffers pointers back to hardware. Also on the transmit side this patch sets SMQ MAXLEN to max value to avoid HW length errors for the packets whose size > MTU, eg due to path MTU. Signed-off-by:

VF shares physical link with PF. Admin function (AF) sends notification to PF whenever a link change event happens. PF has to forward the same notification to each of the enabled VF. PF traps START/STOP_RX messages sent by VF to AF to keep track of VF's enabled/disabled state. Signed-off-by:

Added ethtool support for VF devices for - Driver stats, Tx/Rx perqueue stats - Set/show Rx/Tx queue count - Set/show Rx/Tx ring sizes - Set/show IRQ coalescing parameters - RSS configuration etc It's the PF which owns the interface, hence VF cannot display underlying CGX interface stats. Except for this rest ethtool support reuses PF's APIs. Signed-off-by:

On OcteonTx2 silicon there two two types VFs, VFs that share the physical link with their parent SR-IOV PF and the VFs which work in pairs using internal HW loopback channels (LBK). Except for the underlying Rx/Tx channel mapping from netdev functionality perspective they are almost identical. This patch adds netdev driver support for these VFs. Unlike it's parent PF a VF cannot directly communicate with admin function (AF) and it has to go through PF for the same. The mailbox communication with AF works like 'VF <=> PF <=> AF'. Also functionality wise VF and PF are identical, hence to avoid code duplication PF driver's APIs are resued here for HW initialization, packet handling etc etc ie almost everything. For VF driver to compile as module exported few of the existing PF driver APIs. Signed-off-by:

When FLR is initiated for a VF (PCI function level reset), the parent PF gets a interrupt. PF then sends a message to admin function (AF), which then cleanups all resources attached to that VF. Also handled IRQs triggered when master enable bit is cleared or set for VFs. This handler just clears the transaction pending ie TRPEND bit. Signed-off-by:

Added 'sriov_configure' to enable/disable virtual functions (VFs). Also added handling of mailbox messages from these VFs. Admin function (AF) is the only one with all priviliges to configure HW, alloc resources etc etc, PFs and it's VFs have to request AF via mbox for all their needs. But unlike PFs, their VFs cannot send a mbox request directly. A VF shares a mailbox region with it's parent PF, so VF sends a mailbox msg to PF and then PF forwards it to AF. Then AF after processing sends response to PF which it again forwards to VF. This patch adds support for this 'VF <=> PF <=> AF' mailbox communication. Signed-off-by:
