2024-02-27net: ipa: kill IPA_POWER_FLAG_SYSTEMAlex Elder1-10/+3
The SYSTEM IPA power flag is set, cleared, and tested. But nothing happens based on its value when tested, so it serves no purpose. Get rid of this flag. Signed-off-by: Alex Elder <elder@linaro.org> Signed-off-by: Paolo Abeni <pabeni@redhat.com>
2024-02-27net: ipa: don't bother aborting system resumeAlex Elder1-2/+3
The IPA interrupt can fire if there is data to be delivered to a GSI channel that is suspended. This condition occurs in three scenarios. First, runtime power management automatically suspends the IPA hardware after half a second of inactivity. This has nothing to do with system suspend, so a SYSTEM IPA power flag is used to avoid calling pm_wakeup_dev_event() when runtime suspended. Second, if the system is suspended, the receipt of an IPA interrupt should trigger a system resume. Configuring the IPA interrupt for wakeup accomplishes this. Finally, if system suspend is underway and the IPA interrupt fires, we currently call pm_wakeup_dev_event() to abort the system suspend. The IPA driver correctly handles quiescing the hardware before suspending it, so there's really no need to abort a suspend in progress in the third case. We can simply quiesce and suspend things, and be done. Incoming data can still wake the system after it's suspended. The IPA interrupt has wakeup mode enabled, so if it fires *after* we've suspended, it will trigger a wakeup (if not disabled via sysfs). Stop calling pm_wakeup_dev_event() to abort a system suspend in progress in ipa_power_suspend_handler(). Signed-off-by: Alex Elder <elder@linaro.org> Signed-off-by: Paolo Abeni <pabeni@redhat.com>

With commit 34d21de99cea9 ("net: Move {l,t,d}stats allocation to core and convert veth & vrf"), stats allocation could be done on net core instead of this driver. With this new approach, the driver doesn't have to bother with error handling (allocation failure checking, making sure free happens in the right spot, etc). This is core responsibility now.

In particular the xpcs_soft_reset() and xpcs_do_config() functions currently return -1 if invalid auto-negotiation mode is specified. That value might be then passed to the generic kernel subsystems which require a standard kernel errno value. Even though the erroneous conditions are very specific (memory corruption or buggy driver implementation) using a hard-coded -1 literal doesn't seem correct anyway especially when it comes to passing it higher to the network subsystem or printing to the system log.

2024-02-26net: pcs: xpcs: Drop sentinel entry from 2500basex ifaces listSerge Semin1-3/+1
There are currently only two methods (xpcs_find_compat() and xpcs_get_interfaces()) defined in the driver which loop over the available interfaces. All of them rely on the xpcs_compat::num_interfaces field value to get the total number of supported interfaces. Thus the interface arrays are supposed to be filled with actual interface IDs and there is no need in the dummy terminating ID placed at the end of the arrays. Based on the above drop the PHY_INTERFACE_MODE_MAX entry from the xpcs_2500basex_interfaces array and the PHY_INTERFACE_MODE_MAX-based conditional statement from the xpcs_get_interfaces() method as redundant.

2024-02-22bonding: rate-limit bonding driver inspect messagesPraveen Kumar Kannoju1-8/+10
Through the routine bond_mii_monitor(), bonding driver inspects and commits the slave state changes. During the times when slave state change and failure in aqcuiring rtnl lock happen at the same time, the routine bond_mii_monitor() reschedules itself to come around after 1 msec to commit the new state. During this, it executes the routine bond_miimon_inspect() to re-inspect the state chane and prints the corresponding slave state on to the console. Hence we do see a message at every 1 msec till the rtnl lock is acquired and state chage is committed. This patch doesn't change how bond functions. It only simply limits this kind of log flood.

Major changes: ath12k * firmware-2.bin support * support having multiple identical PCI devices (firmware needs to have ATH12K_FW_FEATURE_MULTI_QRTR_ID) * QCN9274: support split-PHY devices * WCN7850: enable Power Save Mode in station mode * WCN7850: P2P support ath11k: * QCA6390 & WCN6855: support 2 concurrent station interfaces * QCA2066 support
2024-02-22net: phy: realtek: Fix rtl8211f_config_init() for RTL8211F(D)(I)-VD-CG PHYSiddharth Vadapalli1-1/+3
Commit bb726b753f75 ("net: phy: realtek: add support for RTL8211F(D)(I)-VD-CG") extended support of the driver from the existing support for RTL8211F(D)(I)-CG PHY to the newer RTL8211F(D)(I)-VD-CG PHY. While that commit indicated that the RTL8211F_PHYCR2 register is not supported by the "VD-CG" PHY model and therefore updated the corresponding section in rtl8211f_config_init() to be invoked conditionally, the call to "genphy_soft_reset()" was left as-is, when it should have also been invoked conditionally. This is because the call to "genphy_soft_reset()" was first introduced by the commit 0a4355c2b7f8 ("net: phy: realtek: add dt property to disable CLKOUT clock") since the RTL8211F guide indicates that a PHY reset should be issued after setting bits in the PHYCR2 register. As the PHYCR2 register is not applicable to the "VD-CG" PHY model, fix the rtl8211f_config_init() function by invoking "genphy_soft_reset()" conditionally based on the presence of the "PHYCR2" register.

2024-02-21net: sparx5: Add spinlock for frame transmission from CPUHoratiu Vultur3-0/+4
Both registers used when doing manual injection or fdma injection are shared between all the net devices of the switch. It was noticed that when having two process which each of them trying to inject frames on different ethernet ports, that the HW started to behave strange, by sending out more frames then expected. When doing fdma injection it is required to set the frame in the DCB and then make sure that the next pointer of the last DCB is invalid. But because there is no locks for this, then easily this pointer between the DCB can be broken and then it would create a loop of DCBs. And that means that the HW will continuously transmit these frames in a loop. Until the SW will break this loop. Therefore to fix this issue, add a spin lock for when accessing the registers for manual or fdma injection.

Fix EST offset for dwmac 5.10. Currently configuring Qbv doesn't work as expected. The schedule is configured, but never confirmed: |[ 128.250219] imx-dwmac 428a0000.ethernet eth1: configured EST The reason seems to be the refactoring of the EST code which set the wrong EST offset for the dwmac 5.10.
