2024-07-10idpf: compile singleq code only under default-n CONFIG_IDPF_SINGLEQAlexander Lobakin
Currently, all HW supporting idpf supports the singleq model, but none of it advertises it by default, as splitq is supported and preferred for multiple reasons. Still, this almost dead code often times adds hotpath branches and redundant cacheline accesses. While it can't currently be removed, add CONFIG_IDPF_SINGLEQ and build the singleq code only when it's enabled manually. This corresponds to -10 Kb of object code size and a good bunch of hotpath checks. idpf_is_queue_model_split() works as a gate and compiles out to `true` when the config option is disabled.

2024-04-24net: intel: introduce {, Intel} Ethernet common libraryAlexander Lobakin
Not a secret there's a ton of code duplication between two and more Intel ethernet modules. Before introducing new changes, which would need to be copied over again, start decoupling the already existing duplicate functionality into a new module, which will be shared between several Intel Ethernet drivers. Add the lookup table which converts 8/10-bit hardware packet type into a parsed bitfield structure for easy checking packet format parameters, such as payload level, IP version, etc. This is currently used by i40e, ice and iavf and it's all the same in all three drivers. The only difference introduced in this implementation is that instead of defining a 256 (or 1024 in case of ice) element array, add unlikely() condition to limit the input to 154 (current maximum non-reserved packet type). There's no reason to waste 600 (or even 3600) bytes only to not hurt very unlikely exception packets. The hash computation function now takes payload level directly as a pkt_hash_type. There's a couple cases when non-IP ptypes are marked as L3 payload and in the previous versions their hash level would be 2, not 3. But skb_set_hash() only sees difference between L4 and non-L4, thus this won't change anything at all. The module is behind the hidden Kconfig symbol, which the drivers will select when needed. The exports are behind 'LIBIE' namespace to limit the scope of the functions. Not that non-HW-specific symbols will live in yet another module, libeth. This is done to easily distinguish pretty generic code ready for reusing by any other vendor and/or for moving the layer up from the code useful in Intel's 1-100G drivers only.

2024-04-08net: handle HAS_IOPORT dependenciesNiklas Schnelle
In a future patch HAS_IOPORT=n will disable inb()/outb() and friends at compile time. We thus need to add HAS_IOPORT as dependency for those drivers requiring them. For the DEFXX driver the use of I/O ports is optional and we only need to fence specific code paths. It also turns out that with HAS_IOPORT handled explicitly HAMRADIO does not need the !S390 dependency and successfully builds the bpqether driver.

2023-02-26ice: remove unnecessary CONFIG_ICE_GNSSJacob Keller
CONFIG_ICE_GNSS was added by commit c7ef8221ca7d ("ice: use GNSS subsystem instead of TTY") as a way to allow the ice driver to optionally support GNSS features without forcing a dependency on CONFIG_GNSS. The original implementation of that commit at [1] used IS_REACHABLE. This was rejected by Olek at [2] with the suggested implementation of CONFIG_ICE_GNSS. Eventually after merging, Linus reported a .config which had CONFIG_ICE_GNSS = y when both GNSS = n and ICE = n. This confused him and he felt that the config option was not useful, and commented about it at [3]. CONFIG_ICE_GNSS is defined to y whenever GNSS = ICE. This results in it being set in cases where both options are not enabled. The goal of CONFIG_ICE_GNSS is to ensure that the GNSS support in the ice driver is enabled when GNSS is enabled. The complaint from Olek about the original IS_REACHABLE was due to the required IS_REACHABLE checks throughout the ice driver code and the fact that ice_gnss.c was compiled regardless of GNSS support. This can be fixed in the Makefile by using ice-$(CONFIG_GNSS) += ice_gnss.o In this case, if GNSS = m and ICE = y, we can result in some confusing behavior where GNSS support is not enabled because its not built in. See [4]. To disallow this, have CONFIG_ICE depend on GNSS || GNSS = n. This ensures that we cannot enable CONFIG_ICE as builtin while GNSS is a module. Drop CONFIG_ICE_GNSS, and replace the IS_ENABLED checks for it with checks for GNSS. Update the Makefile to add the ice_gnss.o object based on CONFIG_GNSS. This works to ensure that GNSS support can optionally be enabled, doesn't have an unnnecessary extra config option, and has Kbuild enforce the dependency such that you can't accidentally enable GNSS as a module and ICE as a builtin.

2023-01-20ice: use GNSS subsystem instead of TTYArkadiusz Kubalewski
Previously support for GNSS was implemented as a TTY driver, it allowed to access GNSS receiver on /dev/ttyGNSS_<bus><func>. Use generic GNSS subsystem API instead of implementing own TTY driver. The receiver is accessible on /dev/gnss<id>. In case of multiple receivers in the OS, correct device can be found by enumerating either: - /sys/class/net/<eth port>/device/gnss/ - /sys/class/gnss/gnss<id>/device/ Using GNSS subsystem is superior to implementing own TTY driver, as the GNSS subsystem was designed solely for this purpose. It also implements TTY driver but in a common and defined way. From user perspective, there is no difference in communicating with a device, except new path to the device shall be used. The device will provide same information to the userspace as the old one, and can be used in the same way, i.e.: old # gpsmon /dev/ttyGNSS_2100_0 new # gpsmon /dev/gnss0 There is no other impact on userspace tools. User expecting onboard GNSS receiver support is required to enable CONFIG_GNSS=y/m in kernel config.

E822 devices on supported platforms can generate a cross timestamp between the platform ART and the device time. This process allows for very precise measurement of the difference between the PTP hardware clock and the platform time. This is only supported if we know the TSC frequency relative to ART, so we do not enable this unless the boot CPU has a known TSC frequency (as required by convert_art_ns_to_tsc). Because PCIe PTM support is not available on all platforms, introduce CONFIG_ICE_HWTS and make it depend on X86 where we know the support exists.

2021-08-13ethernet: fix PTP_1588_CLOCK dependenciesArnd Bergmann
The 'imply' keyword does not do what most people think it does, it only politely asks Kconfig to turn on another symbol, but does not prevent it from being disabled manually or built as a loadable module when the user is built-in. In the ICE driver, the latter now causes a link failure: aarch64-linux-ld: drivers/net/ethernet/intel/ice/ice_main.o: in function `ice_eth_ioctl': ice_main.c:(.text+0x13b0): undefined reference to `ice_ptp_get_ts_config' ice_main.c:(.text+0x13b0): relocation truncated to fit: R_AARCH64_CALL26 against undefined symbol `ice_ptp_get_ts_config' aarch64-linux-ld: ice_main.c:(.text+0x13bc): undefined reference to `ice_ptp_set_ts_config' ice_main.c:(.text+0x13bc): relocation truncated to fit: R_AARCH64_CALL26 against undefined symbol `ice_ptp_set_ts_config' aarch64-linux-ld: drivers/net/ethernet/intel/ice/ice_main.o: in function `ice_prepare_for_reset': ice_main.c:(.text+0x31fc): undefined reference to `ice_ptp_release' ice_main.c:(.text+0x31fc): relocation truncated to fit: R_AARCH64_CALL26 against undefined symbol `ice_ptp_release' aarch64-linux-ld: drivers/net/ethernet/intel/ice/ice_main.o: in function `ice_rebuild': This is a recurring problem in many drivers, and we have discussed it several times befores, without reaching a consensus. I'm providing a link to the previous email thread for reference, which discusses some related problems. To solve the dependency issue better than the 'imply' keyword, introduce a separate Kconfig symbol "CONFIG_PTP_1588_CLOCK_OPTIONAL" that any driver can depend on if it is able to use PTP support when available, but works fine without it. Whenever CONFIG_PTP_1588_CLOCK=m, those drivers are then prevented from being built-in, the same way as with a 'depends on PTP_1588_CLOCK || !PTP_1588_CLOCK' dependency that does the same trick, but that can be rather confusing when you first see it. Since this should cover the dependencies correctly, the IS_REACHABLE() hack in the header is no longer needed now, and can be turned back into a normal IS_ENABLED() check. Any driver that gets the dependency wrong will now cause a link time failure rather than being unable to use PTP support when that is in a loadable module. However, the two recently added ptp_get_vclocks_index() and ptp_convert_timestamp() interfaces are only called from builtin code with ethtool and socket timestamps, so keep the current behavior by stubbing those out completely when PTP is in a loadable module. This should be addressed properly in a follow-up. As Richard suggested, we may want to actually turn PTP support into a 'bool' option later on, preventing it from being a loadable module altogether, which would be one way to solve the problem with the ethtool interface.

2021-04-14ice: replace custom AIM algorithm with kernel's DIM libraryJacob Keller
The ice driver has support for adaptive interrupt moderation, an algorithm for tuning the interrupt rate dynamically. This algorithm is based on various assumptions about ring size, socket buffer size, link speed, SKB overhead, ethernet frame overhead and more. The Linux kernel has support for a dynamic interrupt moderation algorithm known as "dimlib". Replace the custom driver-specific implementation of dynamic interrupt moderation with the kernel's algorithm. The Intel hardware has a different hardware implementation than the originators of the dimlib code had to work with, which requires the driver to use a slightly different set of inputs for the actual moderation values, while getting all the advice from dimlib of better/worse, shift left or right. The change made for this implementation is to use a pair of values for each of the 5 "slots" that the dimlib moderation expects, and the driver will program those pairs when dimlib recommends a slot to use. The currently implementation uses two tables, one for receive and one for transmit, and the pairs of values in each slot set the maximum delay of an interrupt and a maximum number of interrupts per second (both expressed in microseconds). There are two separate kinds of bugs fixed by using DIMLIB, one is UDP single stream send was too slow, and the other is that 8K ping-pong was going to the most aggressive moderation and has much too high latency. The overall result of using DIMLIB is that we meet or exceed our performance expectations set based on the old algorithm.

2020-07-28ice: implement device flash update via devlinkJacob Keller
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 <jacob.e.keller@intel.com> Signed-off-by: David S. Miller <davem@davemloft.net>

2020-03-21ice: enable initial devlink supportJacob Keller
Begin implementing support for the devlink interface with the ice driver. The pf structure is currently memory managed through devres, via a devm_alloc. To mimic this behavior, after allocating the devlink pointer, use devm_add_action to add a teardown action for releasing the devlink memory on exit. The ice hardware is a multi-function PCIe device. Thus, each physical function will get its own devlink instance. This means that each function will be treated independently, with its own parameters and configuration. This is done because the ice driver loads a separate instance for each function. Due to this, the implementation does not enable devlink to manage device-wide resources or configuration, as each physical function will be treated independently. This is done for simplicity, as managing a devlink instance across multiple driver instances would significantly increase the complexity for minimal gain.

The new ability added to the driver to use mii_bus to handle MII related ioctls is causing compile issues when the driver is compiled into the kernel (i.e. not a module). The problem was in selecting MDIO_DEVICE instead of the preferred PHYLIB Kconfig option. The reason being that MDIO_DEVICE had a dependency on PHYLIB and would be compiled as a module when PHYLIB was a module, no matter whether ixgbe was compiled into the kernel.

To keep the old behavior, this is left as 'default y'. The dependency in XFRM_OFFLOAD still causes a circular dependency but is not actually needed because this symbol is not user visible, so removing that dependency on top makes it all work.

2016-11-16ptp_clock: Allow for it to be optionalNicolas Pitre
In order to break the hard dependency between the PTP clock subsystem and ethernet drivers capable of being clock providers, this patch provides simple PTP stub functions to allow linkage of those drivers into the kernel even when the PTP subsystem is configured out. Drivers must be ready to accept NULL from ptp_clock_register() in that case. And to make it possible for PTP to be configured out, the select statement in those driver's Kconfig menu entries is converted to the new "imply" statement. This way the PTP subsystem may have Kconfig dependencies of its own, such as POSIX_TIMERS, without having to make those ethernet drivers unavailable if POSIX timers are cconfigured out. And when support for POSIX timers is selected again then the default config option for PTP clock support will automatically be adjusted accordingly. The pch_gbe driver is a bit special as it relies on extra code in drivers/ptp/ptp_pch.c. Therefore we let the make process descend into drivers/ptp/ even if PTP_1588_CLOCK is unselected.

In addition I updated the socket address family check so that instead of excluding IPv6 we instead abort of type is not IPv4.

The last change is that I pulled the rtnl_lock/unlock into the conditional statement for IXGBE_FLAG2_VXLAN_REREG_NEEDED.
