2021-09-23net: mdiobus: Set FWNODE_FLAG_NEEDS_CHILD_BOUND_ON_ADD for mdiobus parentsSaravana Kannan1-0/+4
There are many instances of PHYs that depend on a switch to supply a resource (Eg: interrupts). Switches also expects the PHYs to be probed by their specific drivers as soon as they are added. If that doesn't happen, then the switch would force the use of generic PHY drivers for the PHY even if the PHY might have specific driver available. fw_devlink=on by design can cause delayed probes of PHY. To avoid, this we need to set the FWNODE_FLAG_NEEDS_CHILD_BOUND_ON_ADD for the switch's fwnode before the PHYs are added. The most generic way to do this is to set this flag for the parent of MDIO busses which is typically the switch. For more context: https://lore.kernel.org/lkml/YTll0i6Rz3WAAYzs@lunn.ch/#t Fixes: ea718c699055 ("Revert "Revert "driver core: Set fw_devlink=on by default""") Suggested-by: Andrew Lunn <andrew@lunn.ch> Signed-off-by: Saravana Kannan <saravanak@google.com> Link: https://lore.kernel.org/r/20210915170940.617415-4-saravanak@google.com Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>
2021-09-23driver core: fw_devlink: Add support for FWNODE_FLAG_NEEDS_CHILD_BOUND_ON_ADDSaravana Kannan1-0/+19
If a parent device is also a supplier to a child device, fw_devlink=on by design delays the probe() of the child device until the probe() of the parent finishes successfully. However, some drivers of such parent devices (where parent is also a supplier) expect the child device to finish probing successfully as soon as they are added using device_add() and before the probe() of the parent device has completed successfully. One example of such a case is discussed in the link mentioned below. Add a flag to make fw_devlink=on not enforce these supplier-consumer relationships, so these drivers can continue working.

2021-09-21driver core: fw_devlink: Improve handling of cyclic dependenciesSaravana Kannan1-5/+12
When we have a dependency of the form: Device-A -> Device-C Device-B Device-C -> Device-B Where, * Indentation denotes "child of" parent in previous line. * X -> Y denotes X is consumer of Y based on firmware (Eg: DT). We have cyclic dependency: device-A -> device-C -> device-B -> device-A fw_devlink current treats device-C -> device-B dependency as an invalid dependency and doesn't enforce it but leaves the rest of the dependencies as is. While the current behavior is necessary, it is not sufficient if the false dependency in this example is actually device-A -> device-C. When this is the case, device-C will correctly probe defer waiting for device-B to be added, but device-A will be incorrectly probe deferred by fw_devlink waiting on device-C to probe successfully. Due to this, none of the devices in the cycle will end up probing. To fix this, we need to go relax all the dependencies in the cycle like we already do in the other instances where fw_devlink detects cycles. A real world example of this was reported[1] and analyzed[2].

2021-09-10of: property: Disable fw_devlink DT support for X86Saravana Kannan1-0/+3
Andre reported fw_devlink=on breaking OLPC XO-1.5 [1]. OLPC XO-1.5 is an X86 system that uses a mix of ACPI and OF to populate devices. The root cause seems to be ISA devices not setting their fwnode field. But trying to figure out how to fix that doesn't seem worth the trouble because the OLPC devicetree is very sparse/limited and fw_devlink only adds the links causing this issue. Considering that there aren't many users of OF in an X86 system, simply fw_devlink DT support for X86.

The ret value might be -EBUSY, caller will think lru lock is still locked but actually NOT. So return -ENOSPC instead. Otherwise we hit list corruption. ttm_bo_cleanup_refs might fail too if BO is not idle. If we return 0, caller(ttm_tt_populate -> ttm_global_swapout ->ttm_device_swapout) will be stuck as we actually did not free any BO memory.

2021-09-09thermal/drivers/qcom/spmi-adc-tm5: Don't abort probing if a sensor is not usedMatthias Kaehlcke1-0/+6
adc_tm5_register_tzd() registers the thermal zone sensors for all channels of the thermal monitor. If the registration of one channel fails the function skips the processing of the remaining channels and returns an error, which results in _probe() being aborted. One of the reasons the registration could fail is that none of the thermal zones is using the channel/sensor, which hardly is a critical error (if it is an error at all). If this case is detected emit a warning and continue with processing the remaining channels.

2021-09-09iommu: Clarify default domain KconfigRobin Murphy1-1/+1
Although strictly it is the AMD and Intel drivers which have an existing expectation of lazy behaviour by default, it ends up being rather unintuitive to describe this literally in Kconfig. Express it instead as an architecture dependency, to clarify that it is a valid config-time decision. The end result is the same since virtio-iommu doesn't support lazy mode and thus falls back to strict at runtime regardless. The per-architecture disparity is a matter of historical expectations: the AMD and Intel drivers have been lazy by default since 2008, and changing that gets noticed by people asking where their I/O throughput has gone. Conversely, Arm-based systems with their wider assortment of IOMMU drivers mostly only support strict mode anyway; only the Arm SMMU drivers have later grown support for passthrough and lazy mode, for users who wanted to explicitly trade off isolation for performance. These days, reducing the default level of isolation in a way which may go unnoticed by users who expect otherwise hardly seems worth risking for the sake of one line of Kconfig, so here's where we are.

Currently, iommu_init_ga() checks and disables IOMMU VAPIC support (i.e. AMD AVIC support in IOMMU) when GAMSup feature bit is not set. However it forgets to clear IRQ_POSTING_CAP from the previously set amd_iommu_irq_ops.capability. This triggers an invalid page fault bug during guest VM warm reboot if AVIC is enabled since the irq_remapping_cap(IRQ_POSTING_CAP) is incorrectly set, and crash the system with the following kernel trace.
