Wysocki" <rafael.j.wysocki(a)intel.com> Date: Thu, 23 Oct 2025 19:12:57 +0200 Subject: [PATCH] cpuidle: governors: menu: Select polling state in some more cases A throughput regression of 11% introduced by commit 779b1a1cb13a ("cpuidle: governors: menu: Avoid selecting states with too much latency") has been reported and it is related to the case when the menu governor checks if selecting a proper idle state instead of a polling one makes sense. In particular, it is questionable to do so if the exit latency of the idle state in question exceeds the predicted idle duration, so add a check for that, which is sufficient to make the reported regression go away, and update the related code comment accordingly.

When the connected MAC enables EEE, it causes link instability and communication failures. The issue is reproducible with a iMX8MP and relevant stmmac ethernet port. Since the introduction of phylink-managed EEE support in the stmmac driver, EEE is now enabled by default, leading to issues on systems using the DP83867 PHY. Call phy_disable_eee during phy initialization to prevent EEE from being enabled on DP83867 PHYs.

Only the first invocation of pm_restrict_gfp_mask() will actually restrict the GFP mask and the subsequent calls will warn if there is a mismatch between the expected allowed GFP mask and the actual one. Moreover, if pm_restrict_gfp_mask() is called many times in a row, pm_restore_gfp_mask() needs to be called matching number of times in a row to actually restore the GFP mask. Calling it when the GFP mask has not been restricted will cause it to warn.

Commit da995d538d3a ("s390/pci: implement reset_slot for hotplug slot"), mentions zpci_clear_irq() being called in the path for zpci_hot_reset_device(). But that is not the case anymore and these functions are not called outside of this file. Instead zpci_hot_reset_device() relies on zpci_disable_device() also clearing the IRQs, but misses to reset the zdev->irqs_registered flag. However after a CLP disable/enable reset, the device's IRQ are unregistered, but the flag zdev->irq_registered does not get cleared. It creates an inconsistent state and so arch_restore_msi_irqs() doesn't correctly restore the device's IRQ. This becomes a problem when a PCI driver tries to restore the state of the device through pci_restore_state(). Restore IRQ unconditionally for the device and remove the irq_registered flag as its redundant.
