The notifyq rides on the adminq's interrupt, so there's no need to setup and/or access the notifyq's interrupt index or bound_intr. The driver sets the bound_intr using qcq->intx = -1 for the notifyq, but luckily nothing accesses that field for notifyq. Instead of expecting that remains the case, just clean up the notifyq's interrupt index and bound_intr fields.

Aahil Awatramani authored
Add support for the independent control state machine per IEEE 802.1AX-2008 5.4.15 in addition to the existing implementation of the coupled control state machine. Introduces two new states, AD_MUX_COLLECTING and AD_MUX_DISTRIBUTING in the LACP MUX state machine for separated handling of an initial Collecting state before the Collecting and Distributing state. This enables a port to be in a state where it can receive incoming packets while not still distributing. This is useful for reducing packet loss when a port begins distributing before its partner is able to collect. Added new functions such as bond_set_slave_tx_disabled_flags and bond_set_slave_rx_enabled_flags to precisely manage the port's collecting and distributing states. Previously, there was no dedicated method to disable TX while keeping RX enabled, which this patch addresses. Note that the regular flow process in the kernel's bonding driver remains unaffected by this patch. The extension requires explicit opt-in by the user (in order to ensure no disruptions for existing setups) via netlink support using the new bonding parameter coupled_control. The default value for coupled_control is set to 1 so as to preserve existing behaviour.

Claudiu Beznea says: ==================== net: ravb: Prepare for suspend to RAM and runtime PM support (part 1) This series prepares ravb driver for runtime PM support and adjust the already existing suspend to RAM code to work for RZ/G3S (R9A08G045) SoC. As there are IP versions that switch to module standby when disabling the clocks, and because of module standby IP switches to reset and the register content is lost, to be able to have runtime PM supported for all IP variants, the configuration operations were moved all to ravb_open()/ravb_close() letting the ravb_probe() and ravb_remove() to deal with resource parsing and allocation/free. The ethtool and IOCTL APIs that could have been run asyncronously were adapted to return if the interface is down. As explained in each individual commits description, this should be harmless. Along with it, the series contains preparatory cleanups. The series has been tested on the boards with the following device trees: - r8a7742-iwg21d-q7.dts - r8a774a1-hihope-rzg2m-ex.dts - r9a07g043u11-smarc-rzg2ul.dts - r9a07g054l2-smarc-rzv2l.dts - r9a07g044l2-smarc-rzg2l.dts Changes in v6: - fixed typo in patch 08/15 - re-arranged the tags as my b4 am/shazam placed the Rb tags before author's Sob tag Changes in v5: - collected tags - fixed typos in patches description - improved description for patch 07/15 - collected tags Changes in v4: - changed cover letter title and keep on 15 patches in series to cope with requirement at [1] - add dependency on RESET_CONTROLLER in patch "net: ravb: Make reset controller support mandatory" - use pm_runtime_active() in patch "net: ravb: Move the IRQs get and request in the probe function" - set config more before reading the mac address in patch "net: ravb: Set config mode in ndo_open and reset mode in ndo_close" - collected tags [1] https://www.kernel.org/doc/html/v6.6/process/maintainer-netdev.html#tl-dr Changes in v3: - collected tags - addressed review comments - squashed patch 17/21 ("net: ravb: Keep clock request operations grouped together") from v2 in patch 07/19 ("net: ravb: Move reference clock enable/disable on runtime PM APIs") from v3 - check for ndev->flags & IFF_UP in patch 17/19 and 18/19 instead of checking netif_running() - dropped patch 19/21 ("net: ravb: Do not set promiscuous mode if the interface is down") as the changes there are not necessary as ndev->flags & IFF_UP is already checked at the beginning of __dev_set_rx_mode() - remove code from ravb_open() introduced by patch 20/21 ("net: ravb: Do not apply RX CSUM settings to hardware if the interface is down") from v2 as this is not necessary; driver already takes care of this in ravb_emac_init_rcar() Changes in v2: - rework the driver (mainly, ravb_open() contains now only resource allocation and parsing leaving the settings to ravb_open(); ravb_remove() has been adapted accordingly) to be able to use runtime PM for all IP variants; due to this number of patches increased - adjust previous series to review comments - collected tags - populated driver's own runtime PM ops with enable/disable of reference clock ==================== Link: https://lore.kernel.org/r/20240202084136.3426492-1-claudiu.beznea.uj@bp.renesas.comSigned-off-by: Paolo Abeni <pabeni@redhat.com>

ravb_set_gti() was computing the value of GTI based on the reference clock rate and then applied it to register. This was done on the driver's probe function. In order to implement runtime PM for all IP variants (as some IP variants switches to reset mode (and thus the registers content is lost) when module standby is configured through clock APIs) the GTI setup was split in 2 parts: one computing the value of the GTI register (done in the driver's probe function) and one applying the computed value to register (done in the driver's ndo_open API).

The runtime PM implementation will disable clocks at the end of ravb_probe(). As some IP variants switch to reset mode as a result of setting module standby through clock disable APIs, to implement runtime PM the resource parsing and requesting are moved in the probe function and IP settings are moved in the open function. This is done because at the end of the probe some IP variants will switch anyway to reset mode and the registers content is lost. Also keeping only register settings operations in the ravb_open()/ravb_close() functions will make them faster. Commit moves IRQ requests to ravb_probe() to have all the IRQs ready when the interface is open. As now getting/requesting IRQs is done in a single place there is no need to keep intermediary data (like ravb_rx_irqs[] and ravb_tx_irqs[] arrays or IRQs in struct ravb_private). In order to avoid accessing the IP registers while the IP is runtime suspended (e.g. in the timeframe b/w the probe requests shared IRQs and IP clocks are enabled) in the interrupt handlers were introduced pm_runtime_active() checks. The device runtime PM usage counter has been incremented to avoid disabling the device's clocks while the check is in progress (if any). This is a preparatory change to add runtime PM support for all IP variants.

Reference clock could be or not be part of the power domain. If it is part of the power domain, the power domain takes care of properly setting it. In case it is not part of the power domain and full runtime PM support is available in driver the clock will not be propertly disabled/enabled at runtime. For this, keep the prepare/unprepare operations in the driver's probe()/remove() functions and move the enable/disable in runtime PM functions. By doing this, the previous ravb_runtime_nop() function was renamed ravb_runtime_suspend() and the comment was removed. A proper runtime PM resume function was added (ravb_runtime_resume()). The current driver still don't need to make any register settings on runtime suspend/resume (as expressed in the removed comment) because, currently, pm_runtime_put_sync() is called on the driver remove function. This will be changed in the next commits (that extends the runtime PM support) such that proper register settings (along with runtime resume/suspend) will be done on ravb_open()/ravb_close(). Along with it, the other clock request operations were moved close to reference clock request and prepare to have all the clock requests specific code grouped together.

RZ/G3S can go to deep sleep states where power to most of the SoC parts is off. When resuming from such a state, the Ethernet controller needs to be reinitialized. De-asserting the reset signal for it should also be done. Thus, add reset assert/de-assert on suspend/resume functions. On the resume function, the de-assert was not reverted in case of failures to give the user a chance to restore the interface (e.g., bringing down/up the interface) in case suspend/resume failed.

ravb_rzv2m_hw_info::gptp_ref_clk is enabled only for RZ/V2M. RZ/V2M is an ARM64-based device which selects power domains by default and CONFIG_PM. The RZ/V2M Ethernet DT node has proper power-domain binding available in device tree from the commit that added the Ethernet node. (4872ca1f ("arm64: dts: renesas: r9a09g011: Add ethernet nodes")). Power domain support was available in the rzg2l-cpg.c driver when the Ethernet DT node has been enabled in RZ/V2M device tree. (ef3c613c ("clk: renesas: Add CPG core wrapper for RZ/G2L SoC")). Thus, remove the explicit clock enable for gptp_clk (and treat it as the other clocks are treated) as it is not needed and removing it doesn't break the ABI according to the above explanations. By removing the enable/disable operation from the driver we can add runtime PM support (which operates on clocks) w/o the need to handle the gptp_clk in the Ethernet driver functions like ravb_runtime_nop(). PM domain does all that is needed. Signed-off-by: Claudiu Beznea <claudiu.beznea.uj@bp.renesas.com> Reviewed-by: Sergey Shtylyov <s.shtylyov@omp.ru> Signed-off-by: Paolo Abeni <pabeni@redhat.com>

ravb_poll() initial code used to interrogate the first descriptor of the RX queue in case gPTP is false to determine if ravb_rx() should be called. This is done for non-gPTP IPs. For gPTP IPs the driver PTP-specific information was used to determine if receive function should be called. As every IP has its own receive function that interrogates the RX descriptors list in the same way the ravb_poll() was doing there is no need to double check this in ravb_poll(). Removing the code from ravb_poll() leads to a cleaner code.

This test is time sensitive. It may fail on virtual machines and for debug builds. Continue to run in these environments to get code coverage. But optionally suppress failure for timing errors (only). This is controlled with environment variable KSFT_MACHINE_SLOW. The test continues to return 0 (KSFT_PASS), rather than KSFT_XFAIL as previously discussed. Because making so_txtime.c return that and then making so_txtime.sh capture runs that pass that vs KSFT_FAIL and pass it on added a bunch of (fragile bash) boilerplate, while the result is interpreted the same as KSFT_PASS anyway.

It was pointed out during the review [1] of commit e66bf63a ("net: dsa: qca8k: skip MDIO bus creation if its OF node has status = "disabled"") that we now leak a reference to the "mdio" OF node if it is disabled. This is only a concern when using dynamic OF as far as I can tell (like probing on an overlay), since OF nodes are never freed in the regular case. Additionally, I'm unaware of any actual device trees (in production or elsewhere) which have status = "disabled" for the MDIO OF node. So handling this as a simple enhancement.
