e5f31552 - ethernet: fix PTP_1588_CLOCK dependencies

Thu, 12 Aug 2021 18:33:58 +0000

ethernet: fix PTP_1588_CLOCK dependenciesThe 'imply' keyword does not do what most people think it does, it onlypolitely asks Kconfig to turn on another symbol, but does not preventit from being disabled manually or built as a loadable module when theuser 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 discussedit several times befores, without reaching a consensus. I'm providinga link to the previous email thread for reference, which discussessome related problems.To solve the dependency issue better than the 'imply' keyword, introduce aseparate Kconfig symbol "CONFIG_PTP_1588_CLOCK_OPTIONAL" that any drivercan depend on if it is able to use PTP support when available, but worksfine without it. Whenever CONFIG_PTP_1588_CLOCK=m, those drivers arethen prevented from being built-in, the same way as with a 'depends onPTP_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 backinto a normal IS_ENABLED() check. Any driver that gets the dependencywrong will now cause a link time failure rather than being unable to usePTP support when that is in a loadable module.However, the two recently added ptp_get_vclocks_index() andptp_convert_timestamp() interfaces are only called from builtin code withethtool and socket timestamps, so keep the current behavior by stubbingthose out completely when PTP is in a loadable module. This should beaddressed 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 modulealtogether, which would be one way to solve the problem with the ethtoolinterface.Fixes: 06c16d89d2cb ("ice: register 1588 PTP clock device object for E810 devices")Link: https://lore.kernel.org/netdev/20210804121318.337276-1-arnd@kernel.org/Link: https://lore.kernel.org/netdev/CAK8P3a06enZOf=XyZ+zcAwBczv41UuCTz+=0FMf2gBz1_cOnZQ@mail.gmail.com/Link: https://lore.kernel.org/netdev/CAK8P3a3=eOxE-K25754+fB_-i_0BZzf9a9RfPTX3ppSwu9WZXw@mail.gmail.com/Link: https://lore.kernel.org/netdev/20210726084540.3282344-1-arnd@kernel.org/Acked-by: Shannon Nelson Acked-by: Jacob Keller Acked-by: Richard Cochran Reviewed-by: Vladimir Oltean Signed-off-by: Arnd Bergmann Link: https://lore.kernel.org/r/20210812183509.1362782-1-arnd@kernel.orgSigned-off-by: Jakub Kicinski List of files: /linux-6.15/drivers/net/ethernet/cavium/Kconfig

b6d49cab - net: Make PTP-specific drivers depend on PTP_1588_CLOCK

Wed, 29 Apr 2020 07:59:00 +0000

net: Make PTP-specific drivers depend on PTP_1588_CLOCKCommit d1cbfd771ce8 ("ptp_clock: Allow for it to be optional") changedall PTP-capable Ethernet drivers from `select PTP_1588_CLOCK` to `implyPTP_1588_CLOCK`, "in order to break the hard dependency between the PTPclock subsystem and ethernet drivers capable of being clock providers."As a result it is possible to build PTP-capable Ethernet drivers withoutthe PTP subsystem by deselecting PTP_1588_CLOCK. Drivers are required tohandle the missing dependency gracefully.Some PTP-capable Ethernet drivers (e.g., TI_CPSW) factor their PTP codeout into separate drivers (e.g., TI_CPTS_MOD). The above commit alsochanged these PTP-specific drivers to `imply PTP_1588_CLOCK`, making itpossible to build them without the PTP subsystem. But as GrygoriiStrashko 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 isa configuration error made possible by the above commit. Kconfig shouldnot allow users to create a configuration with missing dependencies thatresults 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 arelikely nonfunctional without PTP_1588_CLOCK: NET_DSA_MV88E6XXX_PTP NET_DSA_SJA1105_PTP MACB_USE_HWSTAMP CAVIUM_PTP TI_CPTS_MODNote 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 hasits 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 onPTP_1588_CLOCK (`imply` or otherwise); adding a `depends on PTP_1588_CLOCK`here seems appropriate.Cc: Arnd Bergmann Cc: Richard Cochran Cc: Nicolas Pitre Cc: Grygorii Strashko Cc: Geert Uytterhoeven Fixes: d1cbfd771ce8 ("ptp_clock: Allow for it to be optional")Signed-off-by: Clay McClure Signed-off-by: David S.

d1cbfd77 - ptp_clock: Allow for it to be optional

Fri, 11 Nov 2016 05:10:07 +0000

ptp_clock: Allow for it to be optionalIn order to break the hard dependency between the PTP clock subsystem andethernet drivers capable of being clock providers, this patch providessimple PTP stub functions to allow linkage of those drivers into thekernel even when the PTP subsystem is configured out. Drivers must beready to accept NULL from ptp_clock_register() in that case.And to make it possible for PTP to be configured out, the select statementin those driver's Kconfig menu entries is converted to the new "imply"statement. This way the PTP subsystem may have Kconfig dependencies ofits own, such as POSIX_TIMERS, without having to make those ethernetdrivers unavailable if POSIX timers are cconfigured out. And when supportfor POSIX timers is selected again then the default config option for PTPclock support will automatically be adjusted accordingly.The pch_gbe driver is a bit special as it relies on extra code indrivers/ptp/ptp_pch.c. Therefore we let the make process descend intodrivers/ptp/ even if PTP_1588_CLOCK is unselected.Signed-off-by: Nicolas Pitre Acked-by: Richard Cochran Acked-by: Edward Cree Acked-by: Thomas Gleixner Acked-by: John Stultz Reviewed-by: Josh Triplett Cc: Paul Bolle Cc: linux-kbuild@vger.kernel.orgCc: netdev@vger.kernel.orgCc: Michal Marek Link: http://lkml.kernel.org/r/1478841010-28605-4-git-send-email-nicolas.pitre@linaro.orgSigned-off-by: Thomas Gleixner List of files: /linux-6.15/drivers/net/ethernet/cavium/Kconfig
