2025-05-21iommu/arm-smmu: Move handing of RESUME to the context fault handlerConnor Abbott
The upper layer fault handler is now expected to handle everything required to retry the transaction or dump state related to it, since we enable threaded IRQs. This means that we can take charge of writing RESUME, making sure that we always write it after writing FSR as recommended by the specification. The iommu handler should write -EAGAIN if a transaction needs to be retried. This avoids tricky cross-tree changes in drm/msm, since it never wants to retry the transaction and it already returns 0 from its fault handler. Therefore it will continue to correctly terminate the transaction without any changes required. devcoredumps from drm/msm will temporarily be broken until it is fixed to collect devcoredumps inside its fault handler, but fixing that first would actually be worse because MMU-500 ignores writes to RESUME unless all fields of FSR (except SS of course) are clear and raises an interrupt when only SS is asserted. Right now, things happen to work most of the time if we collect a devcoredump, because RESUME is written asynchronously in the fault worker after the fault handler clears FSR and finishes, although there will be some spurious faults, but if this is changed before this commit fixes the FSR/RESUME write order then SS will never be cleared, the interrupt will never be cleared, and the whole system will hang every time a fault happens. It will therefore help bisectability if this commit goes first. I've changed the TBU path to also accept -EAGAIN and do the same thing, while keeping the old -EBUSY behavior. Although the old path was broken because you'd get a storm of interrupts due to returning IRQ_NONE that would eventually result in the interrupt being disabled, and I think it was dead code anyway, so it should eventually be deleted. Note that drm/msm never uses TBU so this is untested.

2025-05-21iommu/arm-smmu-qcom: Enable threaded IRQ for Adreno SMMUv2/MMU500Connor Abbott
The recommended flow for stall-on-fault in SMMUv2 is the following: 1. Resolve the fault. 2. Write to FSR to clear the fault bits. 3. Write RESUME to retry or fail the transaction. MMU500 is designed with this sequence in mind. For example, experimentally we have seen on MMU500 that writing RESUME does not clear FSR.SS unless the original fault is cleared in FSR, so 2 must come before 3. FSR.SS is allowed to signal a fault (and does on MMU500) so that if we try to do 2 -> 1 -> 3 (while exiting from the fault handler after 2) we can get duplicate faults without hacks to disable interrupts. However, resolving the fault typically requires lengthy operations that can stall, like bringing in pages from disk. The only current user, drm/msm, dumps GPU state before failing the transaction which indeed can stall. Therefore, from now on we will require implementations that want to use stall-on-fault to also enable threaded IRQs. Do that with the Adreno MMU implementations.

The device is supposed to provide the same length back to the driver. But yes, it's possible (like shown in the report) to alter the value to something that causes a crash/panic due to overrun. This patch addresses the issue by adding the size to the common device context, so p54_rx_eeprom_readback no longer relies on possibly tampered values... That said, it also checks if the "firmware" altered the value and no longer copies them. The one, small saving grace is: Before the driver tries to read the eeprom, it needs to upload >a< firmware. the vendor firmware has a proprietary license and as a reason, it is not present on most distributions by default.

2025-05-20net: lan743x: Restore SGMII CTRL register on resumeThangaraj Samynathan
SGMII_CTRL register, which specifies the active interface, was not properly restored when resuming from suspend. This led to incorrect interface selection after resume particularly in scenarios involving the FPGA. To fix this: - Move the SGMII_CTRL setup out of the probe function. - Initialize the register in the hardware initialization helper function, which is called during both device initialization and resume. This ensures the interface configuration is consistently restored after suspend/resume cycles.

netdev_lock is already held when calling bnxt_ulp_irq_stop() and bnxt_ulp_irq_restart(). When converting rtnl_lock to netdev_lock, the original code was rtnl_dereference() to indicate that rtnl_lock was already held. rcu_dereference_protected() is the correct conversion after replacing rtnl_lock with netdev_lock.

After UFS_ABORT_TASK has been processed successfully, the host will generate MCQ IRQ for ABORT TAG with response OCS_ABORTED. This results in ufshcd_compl_one_cqe() calling ufshcd_release_scsi_cmd(). But ufshcd_mcq_abort() already calls ufshcd_release_scsi_cmd(), resulting in __ufshcd_release() being called twice.

While the MDIO address of the internal PHY on Allwinner sun8i chips is generally 1, of_mdio_parse_addr is used to cleanly parse the address from the device-tree instead of hardcoding it. A commit reworking the code ditched the parsed value and hardcoded the value 1 instead, which didn't really break anything but is more fragile and not future-proof. Restore the initial behavior using the parsed address returned from the helper.
