2021-06-11ice: register 1588 PTP clock device object for E810 devicesJacob Keller1-0/+11
Add a new ice_ptp.c file for holding the basic PTP clock interface functions. If the device supports PTP, call the new ice_ptp_init and ice_ptp_release functions where appropriate. If the function owns the hardware resource associated with the PTP hardware clock, register with the PTP_1588_CLOCK infrastructure to allocate a new clock object that represents the device hardware clock. Implement basic functionality for reading and setting the clock time, performing clock adjustments, and adjusting the clock frequency. Future changes will introduce functionality for handling related features including Tx and Rx timestamps.

2021-06-11ice: add support for set/get of driver-stored firmware parametersJacob Keller1-0/+75
Depending on the device configuration, the ice hardware may share the PTP hardware clock timer between multiple PFs. Each PF is informed by firmware during initialization of the PTP timer association. When bringing up PTP, only the PFs which own the timer shall allocate a PTP hardware clock. Other PFs associated with that timer must report the correct PTP clock index in order to allow userspace software the ability to know which ports are connected to the same clock. To support this, the firmware has driver shared parameters. These parameters enable one PF to write the clock index into firmware, and have other PFs read the associated value out. This enables the driver to have only a single PF allocate and control the device timer registers, while other PFs associated with that timer can report the correct clock in the ETHTOOL_GET_TS_INFO report. Add support for the necessary admin queue commands to enable reading and writing of the driver shared parameters. This will be used in a future change to enable sharing the PTP clock index between PF drivers.

2021-06-11ice: add support for sideband messagesJacob Keller1-0/+58
In order to support certain device features, including enabling the PTP hardware clock, the ice driver needs to control some registers on the device PHY. These registers are accessed by sending sideband messages. For some hardware, these messages must be sent over the device admin queue, while other hardware has a dedicated control queue for the sideband messages. Add the neighbor device message structure for sending a message to the neighboring device. Where supported, initialize the sideband control queue and handle cleanup. Add a wrapper function for sending sideband control queue messages that read or write a neighboring device register. Because some devices send sideband messages over the AdminQ, also increase the length of the admin queue to allow more messages to be queued up. This is important because the sideband messages add additional pressure on the AQ usage. This support will be used in following patches to enable support for CONFIG_1588_PTP_CLOCK.

Beyond a specific version of firmware, there is no need to provide override values to the firmware when setting PHY capabilities. In this case, we do not need to indicate whether we're in Strict or Lenient Link Mode. In the case of translating capabilities to the configuration structure, the module compliance enforcement is already correctly set by firmware, so the extra code block is redundant.

There is an issue with some NVMs where an already existent LLDP filter is blocking the creation of a filter to allow LLDP packets to be redirected to the default VSI for the interface. This is blocking all LLDP functionality based in the kernel when the FW LLDP agent is disabled (e.g. software based DCBx).

2020-09-30ice: preserve NVM capabilities in safe modeJacob Keller1-22/+27
If the driver initializes in safe mode, it will call ice_set_safe_mode_caps. This results in clearing the capabilities structures, in order to set them up for operating in safe mode, ensuring many features are disabled. This has a side effect of also clearing the capability bits that relate to NVM update. The result is that the device driver will not indicate support for unified update, even if the firmware is capable. Fix this by adding the relevant capability fields to the list of values we preserve. To simplify the code, use a common_cap structure instead of a handful of local variables. To reduce some duplication of the capability name, introduce a couple of macros used to restore the capabilities values from the cached copy.

2020-08-01ice: rename misleading grst_delay variableNick Nunley1-5/+5
The grst_delay variable in ice_check_reset contains the maximum time (in 100 msec units) that the driver will wait for a reset event to transition to the Device Active state. The value is the sum of three separate components: 1) The maximum time it may take for the firmware to process its outstanding command before handling the reset request. 2) The value in RSTCTL.GRSTDEL (the delay firmware inserts between first seeing the driver reset request and the actual hardware assertion). 3) The maximum expected reset processing time in hardware. Referring to this total time as "grst_delay" is misleading and potentially confusing to someone checking the code and cross-referencing the hardware specification. Fix this by renaming the variable to "grst_timeout", which is more descriptive of its actual use.

2020-07-28ice: implement device flash update via devlinkJacob Keller1-1/+1
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]>

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).

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. As there are no other callers, it is safe to now remove ice_aq_discover_caps and ice_parse_caps.

2020-07-23ice: split ice_parse_caps into separate functionsJacob Keller1-170/+378

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.

2020-07-23ice: refactor ice_discover_caps to avoid need to retryJacob Keller1-31/+12
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.

2020-07-01ice: replace single-element array used for C struct hackBruce Allan1-35/+39
Convert the pre-C90-extension "C struct hack" method (using a single- element array at the end of a structure for implementing variable-length types) to the preferred use of C99 flexible array member. Additional code cleanups were done near areas affected by this change.

2020-07-01ice: avoid unnecessary single-member variable-length structsBruce Allan1-17/+12
There are a number of structures that consist of a one-element array as the only struct member. Some of those are unused so remove them. Others are used to index into a buffer/array consisting of a variable number of a different data or structure type. Those are unnecessary since we can use simple pointer arithmetic or index directly into the buffer to access individual elements of the buffer/array. Additional code cleanups were done near areas affected by this change.

2020-07-01ice: implement snapshot for device capabilitiesJacob Keller1-13/+51
Add a new devlink region used for capturing a snapshot of the device capabilities buffer which is reported by the firmware over the AdminQ. This information can useful in debugging driver and firmware interactions.

2020-05-31ice: Ignore EMODE when setting PHY configChinh T Cao1-1/+6
When setting the PHY cfg (CQ cmd 0x0601), if the firmware responds with an EMODE error, software will ignore the error as it simply means that manageability (ex: BMC) is in control of the link and that the new setting may not be applied.
