2021-08-14ethernet: fix PTP_1588_CLOCK dependenciesArnd Bergmann1-0/+1
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.

2020-05-02net: Make PTP-specific drivers depend on PTP_1588_CLOCKClay McClure1-1/+1
Commit d1cbfd771ce8 ("ptp_clock: Allow for it to be optional") changed all PTP-capable Ethernet drivers from `select PTP_1588_CLOCK` to `imply PTP_1588_CLOCK`, "in order to break the hard dependency between the PTP clock subsystem and ethernet drivers capable of being clock providers." As a result it is possible to build PTP-capable Ethernet drivers without the PTP subsystem by deselecting PTP_1588_CLOCK. Drivers are required to handle the missing dependency gracefully. Some PTP-capable Ethernet drivers (e.g., TI_CPSW) factor their PTP code out into separate drivers (e.g., TI_CPTS_MOD). The above commit also changed these PTP-specific drivers to `imply PTP_1588_CLOCK`, making it possible to build them without the PTP subsystem. But as Grygorii Strashko noted in [1]: On Wed, Apr 22, 2020 at 02:16:11PM +0300, Grygorii Strashko wrote: > Another question is that CPTS completely nonfunctional in this case and > it was never expected that somebody will even try to use/run such > configuration (except for random build purposes). In my view, enabling a PTP-specific driver without the PTP subsystem is a configuration error made possible by the above commit. Kconfig should not allow users to create a configuration with missing dependencies that results in "completely nonfunctional" drivers. I audited all network drivers that call ptp_clock_register() but merely `imply PTP_1588_CLOCK` and found five PTP-specific drivers that are likely nonfunctional without PTP_1588_CLOCK: NET_DSA_MV88E6XXX_PTP NET_DSA_SJA1105_PTP MACB_USE_HWSTAMP CAVIUM_PTP TI_CPTS_MOD Note how these symbols all reference PTP or timestamping in their name; this is a clue that they depend on PTP_1588_CLOCK. Change them from `imply PTP_1588_CLOCK` [2] to `depends on PTP_1588_CLOCK`. I'm not using `select PTP_1588_CLOCK` here because PTP_1588_CLOCK has its own dependencies, which `select` would not transitively apply. Additionally, remove the `select NET_PTP_CLASSIFY` from CPTS_TI_MOD; PTP_1588_CLOCK already selects that. [1]: https://lore.kernel.org/lkml/c04458ed-29ee-1797-3a11-7f3f560553e6@ti.com/ [2]: NET_DSA_SJA1105_PTP had never declared any type of dependency on PTP_1588_CLOCK (`imply` or otherwise); adding a `depends on PTP_1588_CLOCK` here seems appropriate.

This patch converts the MACB Ethernet driver to the Phylink framework. The MAC configuration is moved to the Phylink ops and Phylink helpers are now used in the ethtools functions. This helps to access the flow control and pauseparam logic and this will be helpful in the future for boards using this controller with SFP cages.

2019-06-27net: macb: Kconfig: Rename Atmel to CadencePalmer Dabbelt1-3/+3
The help text makes it look like NET_VENDOR_CADENCE enables support for Atmel devices, when in reality it's a driver written by Atmel that supports Cadence devices. This may confuse users that have this device on a non-Atmel SoC. The fix is just s/Atmel/Cadence/, but I did go and re-wrap the Kconfig help text as that change caused it to go over 80 characters.

2019-06-27net: macb: Kconfig: Make MACB depend on COMMON_CLKPalmer Dabbelt1-2/+2
commit c218ad559020 ("macb: Add support for SiFive FU540-C000") added a dependency on the common clock framework to the macb driver, but didn't express that dependency in Kconfig. As a result macb now fails to compile on systems without COMMON_CLK, which specifically causes a build failure on powerpc allyesconfig. This patch adds the dependency, which results in the macb driver no longer being selectable on systems without the common clock framework. All known systems that have this device already support the common clock framework, so this should not cause trouble for any uses. Supporting both the FU540-C000 and systems without COMMON_CLK is quite ugly. I've build tested this on powerpc allyesconfig and RISC-V defconfig (which selects MACB), but I have not even booted the resulting kernels.

This howto made sense in the 1990s when users had to manually configure ISA cards with jumpers or vendor utilities, but with the implementation of PCI it became increasingly less and less relevant, to the point where it has been well over a decade since I last updated it. And there is no value in anyone else taking over updating it either. However the references to it continue to spread as boiler plate text from one Kconfig file into the next. We are not doing end users any favours by pointing them at this old document, so lets kill it with fire, once and for all, to hopefully stop any further spread.

macb and at91_ether drivers can be compiled as modules, but the at91_ether driver use some functions and variables defined in the macb one, thus creating a dependency on the macb driver. Since these drivers are sharing the same logic we can easily merge at91_ether into macb. In order to factorize common probing logic we've added an ->init() function to struct macb_config (the structure associated with the compatible string), and moved macb specific init code from macb_probe to macb_init.

2011-11-22macb: initial support for Cadence GEMJamie Iles1-7/+9
The Cadence GEM is based on the MACB Ethernet controller but has a few small changes with regards to register and bitfield placement. This patch detects the presence of a GEM by reading the module ID register and setting a flag appropriately. This handles the new HW address, USRIO and hash register base register locations in GEM. v3: - convert to macb_is_gem() inline rather than storing a boolean flag - handle rx_overrun stats for gem Acked-by: David S.

2011-09-15MII: fix Kconfig dependencies for MIIJeff Kirsher1-0/+1
MII Kconfig option is apart of the core networking drivers and by default NET_CORE is enabled so drivers selecting MII will have MII enabled as well. It was found using the randconfig option during testing, MII would be selected but NET_CORE could be disabled. This caused a dependency error. Resolved the dependency by selecting NET_CORE when MII is selected.
