2020-07-29ice: distribute Tx queues evenlyVictor Raj1-4/+51
Distribute the Tx queues evenly across all queue groups. This will help the queues to get more equal sharing among the queues when all are in use. In the previous algorithm, the next queue group node will be picked up only after the previous one filled with max children. For example: if VSI is configured with 9 queues, the first 8 queues will be assigned to queue group 1 and the 9th queue will be assigned to queue group 2. The 2 queue groups split the bandwidth between them equally (50:50). The first queue group node will share the 50% bandwidth with all of its children (8 queues). And the second queue group node will share the entire 50% bandwidth with its only children. The new algorithm will fix this issue.

By default the queues are configured in legacy mode. The default BW settings for legacy/advanced modes are different. The existing code was using the advanced mode default value of 1 which was incorrect. This caused the unbalanced BW sharing among siblings. The recommended default value is applied.

2020-07-29ice: fix overwriting TX/RX descriptor values when rebuilding VSIPaul M Stillwell Jr1-2/+8
If a user sets the value of the TX or RX descriptors to some non-default value using 'ethtool -G' then we need to not overwrite the values when we rebuild the VSI. The VSI rebuild could happen as a result of a user setting the number of queues via the 'ethtool -L' command. Fix this by checking to see if the value we have stored is non-zero and if it is then don't change the value.

Return ICE_ERR_DOES_NOT_EXIST return code if admin command error code is ICE_AQ_RC_ENOENT (not exist). ice_aq_sw_rules is used when switch rule is getting added/deleted/updated. In case of delete/update switch rule, admin command can return ICE_AQ_RC_ENOENT error code if such rule does not exist, hence return ICE_ERR_DOES_NOT_EXIST error code from ice_aq_sw_rule, so that caller of this function can decide how to handle ICE_ERR_DOES_NOT_EXIST.

2020-07-29ice: restore VF MSI-X state during PCI resetNick Nunley3-0/+34
During a PCI FLR the MSI-X Enable flag in the VF PCI MSI-X capability register will be cleared. This can lead to issues when a VF is assigned to a VM because in these cases the VF driver receives no indication of the PF PCI error/reset and additionally it is incapable of restoring the cleared flag in the hypervisor configuration space without fully reinitializing the driver interrupt functionality. Since the VF driver is unable to easily resolve this condition on its own, restore the VF MSI-X flag during the PF PCI reset handling.

2020-07-29ice: fix link event handling timingDave Ertman2-1/+7
When the driver experiences a link event (especially link up) there can be multiple events generated. Some of these are link fault and still have a state of DOWN set. The problem happens when the link comes UP during the PF driver handling one of the LINK DOWN events. The status of the link is updated and is now seen as UP, so when the actual LINK UP event comes, the port information has already been updated to be seen as UP, even though none of the UP activities have been completed. After the link information has been updated in the link handler and evaluated for MEDIA PRESENT, if the state of the link has been changed to UP, treat the DOWN event as an UP event since the link is now UP.

2020-07-29ice: Fix link broken after GLOBR resetDave Ertman1-4/+0
After a GLOBR, the link was broken so that a link up situation was being seen as a link down. The problem was that the rebuild process was updating the port_info link status without doing any of the other things that need to be done when link changes. This was causing the port_info struct to have current "UP" information so that any further UP interrupts were skipped as redundant. The rebuild flow should *not* be updating the port_info struct link information, so eliminate this and leave it to the link event handling code.

2020-07-28ice: implement device flash update via devlinkJacob Keller9-1/+1007
Use the newly added pldmfw library to implement device flash update for the Intel ice networking device driver. This support uses the devlink flash update interface. The main parts of the flash include the Option ROM, the netlist module, and the main NVM data. The PLDM firmware file contains modules for each of these components. Using the pldmfw library, the provided firmware file will be scanned for the three major components, "fw.undi" for the Option ROM, "fw.mgmt" for the main NVM module containing the primary device firmware, and "fw.netlist" containing the netlist module. The flash is separated into two banks, the active bank containing the running firmware, and the inactive bank which we use for update. Each module is updated in a staged process. First, the inactive bank is erased, preparing the device for update. Second, the contents of the component are copied to the inactive portion of the flash. After all components are updated, the driver signals the device to switch the active bank during the next EMP reset (which would usually occur during the next reboot). Although the firmware AdminQ interface does report an immediate status for each command, the NVM erase and NVM write commands receive status asynchronously. The driver must not continue writing until previous erase and write commands have finished. The real status of the NVM commands is returned over the receive AdminQ. Implement a simple interface that uses a wait queue so that the main update thread can sleep until the completion status is reported by firmware. For erasing the inactive banks, this can take quite a while in practice. To help visualize the process to the devlink application and other applications based on the devlink netlink interface, status is reported via the devlink_flash_update_status_notify. While we do report status after each 4k block when writing, there is no real status we can report during erasing. We simply must wait for the complete module erasure to finish. With this implementation, basic flash update for the ice hardware is supported. Signed-off-by: Jacob Keller <[email protected]> Signed-off-by: David S. Miller <[email protected]>

There isn't a case for 1G SGMII in ice_get_media_type() so add the handling for it. Also handle the special case where some direct attach cables may report that they support 1G SGMII, but that is erroneous since SGMII is supposed to be a backplane media type (between a MAC and a PHY). If the driver doesn't handle this special case then a user could see the 'Port' in ethtool change from 'Direct attach Copper' to 'Backplane' when they have forced the speed to 1G, but the cable hasn't changed. Lastly, change ice_aq_get_phy_caps() to save the module_type info if the function was called with ICE_AQC_REPORT_TOPO_CAP. This call uses the media information to populate the module_type.

Using the new ice_aq_list_caps and ice_parse_(dev|func)_caps functions, replace ice_discover_caps with two functions that each take a pointer to the dev_caps and func_caps structures respectively. This makes the side effect of updating the hw->dev_caps and hw->func_caps obvious from reading the implementation of the function. Additionally, it opens the way for enabling reading of device capabilities outside of the initialization flow. By passing in a pointer, another caller will be able to read the capabilities without modifying the HW capabilities structures.

The current implementation directly updates the hw->func_caps and hw->dev_caps structures. It is directly called from within ice_aq_discover_caps. This causes the discover_caps function to have the side effect of modifying the HW capability structures, which is not intuitive. Split this function into ice_parse_dev_caps and ice_parse_func_caps. These functions will take a pointer to the dev_caps and func_caps respectively. Also create an ice_parse_common_caps for sharing the capability logic that is common to device and function. Doing so enables a future refactor to allow reading and parsing capabilities into a local caps structure instead of modifying the members of the HW structure directly.

The ice_discover_caps function is used to read the device and function capabilities, updating the hardware capabilities structures with relevant data. The exact number of capabilities returned by the hardware is unknown ahead of time. The AdminQ command will report the total number of capabilities in the return buffer. The current implementation involves requesting capabilities once, reading this returned size, and then re-requested with that size. This isn't really necessary. The firmware interface has a maximum size of ICE_AQ_MAX_BUF_LEN. Firmware can never return more than ICE_AQ_MAX_BUF_LEN / sizeof(struct ice_aqc_list_caps_elem) capabilities. Avoid the retry loop by simply allocating a buffer of size ICE_AQ_MAX_BUF_LEN. This is significantly simpler than retrying. The extra allocation isn't a big deal, as it will be released after we finish parsing the capabilities.

2020-07-07PCI: Use 'pci_channel_state_t' instead of 'enum pci_channel_state'Luc Van Oostenryck3-4/+4
The method struct pci_error_handlers.error_detected() is defined and documented as taking an 'enum pci_channel_state' for the second argument, but most drivers use 'pci_channel_state_t' instead. This 'pci_channel_state_t' is not a typedef for the enum but a typedef for a bitwise type in order to have better/stricter typechecking. Consolidate everything by using 'pci_channel_state_t' in the method's definition, in the related helpers and in the drivers. Enforce use of 'pci_channel_state_t' by replacing 'enum pci_channel_state' with an anonymous 'enum'. Note: Currently, from a typechecking point of view this patch changes nothing because only the constants defined by the enum are bitwise, not the enum itself (sparse doesn't have the notion of 'bitwise enum'). This may change in some not too far future, hence the patch.

2020-07-01ixgbe: Cleanup unneeded delay in ethtool testJeff Kirsher1-4/+1
There is a 4 seconds delay in ixgbe_diag_test() that is holding up other ioctls such as SIOCGIFCONF that Oracle database applications use. One of Oracle's product runs "ethtool -t ethX online" periodically for system monitoring and that is impacting database applications that use SIOCGIFCONF at that same time. This 4 second delay was needed in out early 1GbE parts to give the PHY time to recover from a reset. This code was carried forward to the 10 GbE driver even it was not needed for the supported PHYs in the ixgbe driver.

2020-07-01iavf: Fix updating statisticsTony Nguyen1-1/+4
Commit bac8486116b0 ("iavf: Refactor the watchdog state machine") inverted the logic for when to update statistics. Statistics should be updated when no other commands are pending, instead they were only requested when a command was processed. iavf_request_stats() would see a pending request and not request statistics to be updated. This caused statistics to never be updated; fix the logic.
