2024-08-26nfsd: hold reference to delegation when updating it for cb_getattrJeff Layton1-3/+7
Once we've dropped the flc_lock, there is nothing that ensures that the delegation that was found will still be around later.

2024-08-26wifi: iwlwifi: mvm: don't wait for tx queues if firmware is deadEmmanuel Grumbach1-1/+8
There is a WARNING in iwl_trans_wait_tx_queues_empty() (that was recently converted from just a message), that can be hit if we wait for TX queues to become empty after firmware died. Clearly, we can't expect anything from the firmware after it's declared dead. Don't call iwl_trans_wait_tx_queues_empty() in this case. While it could be a good idea to stop the flow earlier, the flush functions do some maintenance work that is not related to the firmware, so keep that part of the code running even when the firmware is not running.

2024-08-26wifi: iwlwifi: mvm: fix hibernationEmmanuel Grumbach4-4/+76
Fast resume is a feature that was recently introduced to speed up the resume time. It basically keeps the firmware alive while the system is suspended and that avoids starting again the whole device. This flow can't work for hibernation, since when the system boots, before the frozen image is loaded, the kernel may touch the device. As a result, we can't assume the device is in the exact same state as before the hibernation. Detect that we are resuming from hibernation through the PCI device and forbid the fast resume flow. We also need to shut down the device cleanly when that happens. In addition, in case the device is power gated during S3, we won't be able to keep the device alive. Detect this situation with BE200 at least with the help of the CSR_FUNC_SCRATCH register and reset the device upon resume if it was power gated during S3.

2024-08-26LoongArch: KVM: Invalidate guest steal time address on vCPU resetBibo Mao3-9/+1
If ParaVirt steal time feature is enabled, there is a percpu gpa address passed from guest vCPU and host modifies guest memory space with this gpa address. When vCPU is reset normally, it will notify host and invalidate gpa address. However if VM is crashed and VMM reboots VM forcely, the vCPU reboot notification callback will not be called in VM. Host needs invalidate the gpa address, else host will modify guest memory during VM reboots. Here it is invalidated from the vCPU KVM_REG_LOONGARCH_VCPU_RESET ioctl interface. Also funciton kvm_reset_timer() is removed at vCPU reset stage, since SW emulated timer is only used in vCPU block state. When a vCPU is removed from the block waiting queue, kvm_restore_timer() is called and SW timer is cancelled. And the timer register is also cleared at VMM when a vCPU is reset.

2024-08-26nvme-rdma: send cntlid in the RDMA_CM_REQUEST Private DataNiklas Cassel2-1/+7
When sending a RDMA_CM_REQUEST, the NVMe RDMA Transport Specification allows you to populate the cntlid field in the RDMA_CM_REQUEST Private Data. The cntlid is returned by the target on completion of the first RDMA_CM_REQUEST command (which creates the admin queue). The cntlid field can then be populated by the host when the I/O queues are created (using additional RDMA_CM_REQUEST commands), such that the target can perform extra validation for additional RDMA_CM_REQUEST commands. This additional error code and error message is also added, such that nvme_rdma_cm_msg() will display the proper error message if the target fails the RDMA_CM_REQUEST command because of this extra validation.

2024-08-26platform/x86/intel-uncore-freq: Do not present separate package-die domainSrinivas Pandruvada1-1/+6
The scope of uncore control is per power domain with TPMI. There are two types of processor topologies can be presented by CPUID extended topology leaf irrespective of the hardware architecture: 1. A die is not enumerated in CPUID. In this case there is only one die in a package is visible. In this case there can be multiple power domains in a single die. 2. A power domain in a package is enumerated as a die in CPUID. So there is one power domain per die. To allow die level controls, the current implementation creates a root domain and aggregates all information from power domains in it. This is well suited for configuration 1 above. But for configuration 2 above, the root domain will present the same information as present by power domain. So, no use of aggregating. To check the configuration, call topology_max_dies_per_package(). If it is more than one, avoid creating root domain.

2024-08-26drm/i915: ARL requires a newer GSC firmwareJohn Harrison6-6/+58
ARL and MTL share a single GSC firmware blob. However, ARL requires a newer version of it. So add differentiate of the PCI ids for ARL from MTL and create ARL as a sub-platform of MTL. That way, all the existing workarounds and such still treat ARL as MTL exactly as before. However, now the GSC code can check for ARL and do an extra version check on the firmware before committing to it. Also, the version extraction code has various ways of failing but the return code was being ignore and so the firmware load would attempt to continue anyway. Fix that by propagating the return code to the next level out.

2024-08-26media: renesas: vsp1: Implement .link_validate() for video devicesLaurent Pinchart1-0/+22
The v4l2_subdev_link_validate() helper prints a warning if the .link_validate() operation is not implemented for video devices connected to the subdevs. Implement the operation to silence the warning. Ideally validation of the link between the video device and the subdev should be implemented in that operation. That would however break userspace that does not configure formats on all video devices before starting streaming. While this mode of operation may not be considered valid by the V4L2 API specification (interpretation differ), it is nonetheless supported by the vsp1 driver at the moment and used by at least the vsp1 unit test suite, and possibly other userspace applications. Removing it would be a regression. Signed-off-by: Laurent Pinchart <[email protected]> Reviewed-by: Tomi Valkeinen <[email protected]> Acked-by: Sakari Ailus <[email protected]>
2024-08-26media: v4l2-subdev: Support hybrid links in v4l2_subdev_link_validate()Laurent Pinchart2-5/+44
The v4l2_subdev_link_validate() helper function is meant to be used as a drop-in implementation of a V4L2 subdev entity .link_validate() handler. It supports subdev-to-subdev links only, and complains if one end of the link is not a subdev. This forces drivers that have video output devices connected to subdevs to implement a custom .link_validate() handler, calling v4l2_subdev_link_validate() for the subdev-to-subdev links, and performing manual link validation for the video-to-subdev links. Video devices embed a media entity, and therefore also have a .link_validate() operation. For video capture devices, the operation should be manually implemented by drivers for validate the subdev-to-video links. For video output devices, on the other hand, that operation is never called, as link validation is performed in the context of the sink entity. As a result, we end up forcing drivers to implement a custom .link_validate() handler for subdevs connected to video output devices, when the video devices provide an operation that could be used for that purpose. To improve that situation, make v4l2_subdev_link_validate() delegate link validation to the source's .link_validate() operation when the link source is a video device and the link sink is a subdev. This allows broader usage of v4l2_subdev_link_validate(), and simplifies drivers by making video device link validation easy to implement in the video device .link_validate(), regardless of whether the video device is an output device or a capture device.

2024-08-26media: v4l2-subdev: Refactor warnings in v4l2_subdev_link_validate()Laurent Pinchart1-5/+9
The v4l2_subdev_link_validate() function prints a one-time warning if it gets called on a link whose source or sink is not a subdev. As links get validated in the context of their sink, a call to the helper when the link's sink is not a subdev indicates that the driver has set its .link_validate() handler to v4l2_subdev_link_validate() on a non-subdev entity, which is a clear driver bug. On the other hand, the link's source not being a subdev indicates that the helper is used for a subdev connected to a video output device, which is a lesser issue, if only because this is currently common practice. There are no drivers left in the kernel that use v4l2_subdev_link_validate() in a context where it may get called on a non-subdev sink. Replace the pr_warn_once() with a WARN_ON_ONCE() in this case to make sure that new offenders won't be introduced. A subsequent change will improve the v4l2_subdev_link_validate() helper to properly support validating video device to subdev links.

2024-08-26media: sun4i_csi: Don't use v4l2_subdev_link_validate() for video deviceLaurent Pinchart1-1/+8
The v4l2_subdev_link_validate() function is a helper designed to validate links whose sink is a subdev. When called on a link whose sink is a video device, it only prints a warning and returns. Its usage in the sun4i_csi driver is wrong, leaving the link from the sub4i_csi subdev to the capture video device unvalidated. Planned improvements to the v4l2_subdev_link_validate() function will turn the warning into an error, breaking the sun4i_csi driver. As an interim measure, move the warning to the sun4i_csi driver in a custom validation handler, and drop the call to the helper.
