2025-06-26interconnect: icc-clk: destroy nodes in case of memory allocation failuresGabor Juhos1-0/+2
When memory allocation fails during creating the name of the nodes in icc_clk_register(), the code continues on the error path and it calls icc_nodes_remove() to destroy the already created nodes. However that function only destroys the nodes which were already added to the provider and the newly created nodes are never destroyed in case of error. In order to avoid a memory leaks, change the code to destroy the newly created nodes explicitly in case of memory allocation failures.

2025-06-26interconnect: increase ICC_DYN_ID_STARTGabor Juhos1-1/+4
Since commit d30f83d278a9 ("interconnect: core: Add dynamic id allocation support"), interconnect node ids greater than or equal to ICC_DYN_ID_START are reserved for dynamic id allocation. Yet the icc_node_create_nolock() function allows to directly use such ids for creating nodes. This can cause problems by executing dynamic id related codepaths even for nodes intended to use static ids. For example, the 'nsscc-ipq9574' driver creates interconnect nodes with static ids starting from 19148. Because these ids belongs to the dynamic id range, the icc_node_add() function replaces the node names unexpectedly. The node names looked like this before the change: # grep nss_cc /sys/kernel/debug/interconnect/interconnect_summary nss_cc_nssnoc_ppe_clk_master 0 0 nss_cc_nssnoc_ppe_clk_slave 0 0 nss_cc_nssnoc_ppe_cfg_clk_master 0 0 ... And those have an unexpected suffix now: # grep nss_cc /sys/kernel/debug/interconnect/interconnect_summary nss_cc_nssnoc_ppe_clk_master@39b00000.clock-controller 0 0 nss_cc_nssnoc_ppe_clk_slave@39b00000.clock-controller 0 0 nss_cc_nssnoc_ppe_cfg_clk_master@39b00000.clock-controller 0 0 ... Increase the value of ICC_DYN_ID_START to avoid this. Also, add sanity check to the icc_node_create_nolock() function to prevent directly creating nodes with ids reserved for dynamic allocation in order to detect these kind of problems.

2025-06-26drm/gpusvm, drm/pagemap: Move migration functionality to drm_pagemapMatthew Brost7-774/+848
The migration functionality and track-keeping of per-pagemap VRAM mapped to the CPU mm is not per GPU_vm, but rather per pagemap. This is also reflected by the functions not needing the drm_gpusvm structures. So move to drm_pagemap. With this, drm_gpusvm shouldn't really access the page zone-device-data since its meaning is internal to drm_pagemap. Currently it's used to reject mapping ranges backed by multiple drm_pagemap allocations. For now, make the zone-device-data a void pointer. Alter the interface of drm_gpusvm_migrate_to_devmem() to ensure we don't pass a gpusvm pointer. Rename CONFIG_DRM_XE_DEVMEM_MIRROR to CONFIG_DRM_XE_PAGEMAP. Matt is listed as author of this commit since he wrote most of the code, and it makes sense to retain his git authorship. Thomas mostly moved the code around. v3: - Kerneldoc fixes (CI) - Don't update documentation about how the drm_pagemap migration should be interpreted until upcoming patches where the functionality is implemented.

2025-06-26ice: default to TIME_REF instead of TXCO on E825-CJacob Keller1-1/+1
The driver currently defaults to the internal oscillator as the clock source for E825-C hardware. While this clock source is labeled TCXO, indicating a temperature compensated oscillator, this is only true for some board designs. Many board designs have a less capable oscillator. The E825-C hardware may also have its clock source set to the TIME_REF pin. This pin is connected to the DPLL and is often a more stable clock source. The choice of the internal oscillator is not suitable for all systems, especially those which want to enable SyncE support. There is currently no interface available for users to configure the clock source. Other variants of the E82x board have the clock source configured in the NVM, but E825-C lacks this capability, so different board designs cannot select a different default clock via firmware. In most setups, the TIME_REF is a suitable default clock source. Additionally, we now fall back to the internal oscillator automatically if the TIME_REF clock source cannot be locked. Change the default clock source for E825-C to TIME_REF. Note that the driver logs a dev_dbg message upon configuring the TSPLL which includes the clock source and frequency. This can be enabled to confirm which clock source is in use. Longterm a proper interface to dynamically introspect and change the clock source will be designed (perhaps some extension of the DPLL subsystem?)

It turns out that the Windows WMI-ACPI driver always enables/disables WMI events regardless of whether they are marked as expensive or not. This finding is further reinforced when reading the documentation of the WMI_FUNCTION_CONTROL_CALLBACK callback used by Windows drivers for enabling/disabling WMI devices: The DpWmiFunctionControl routine enables or disables notification of events, and enables or disables data collection for data blocks that the driver registered as expensive to collect. Follow this behavior to fix the WMI event used for reporting hotkey events on the Dell Latitude 5400 and likely many more devices.

2025-06-26usb: hub: Fix flushing and scheduling of delayed work that tunes runtime pmMathias Nyman1-2/+4
Delayed work to prevent USB3 hubs from runtime-suspending immediately after resume was added in commit 8f5b7e2bec1c ("usb: hub: fix detection of high tier USB3 devices behind suspended hubs"). This delayed work needs be flushed if system suspends, or hub needs to be quiesced for other reasons right after resume. Not flushing it triggered issues on QC SC8280XP CRD board during suspend/resume testing. Fix it by flushing the delayed resume work in hub_quiesce() The delayed work item that allow hub runtime suspend is also scheduled just before calling autopm get. Alan pointed out there is a small risk that work is run before autopm get, which would call autopm put before get, and mess up the runtime pm usage order. Swap the order of work sheduling and calling autopm get to solve this.

2025-06-26drm/i915/selftests: Change mock_request() to return error pointersDan Carpenter2-11/+11
There was an error pointer vs NULL bug in __igt_breadcrumbs_smoketest(). The __mock_request_alloc() function implements the smoketest->request_alloc() function pointer. It was supposed to return error pointers, but it propogates the NULL return from mock_request() so in the event of a failure, it would lead to a NULL pointer dereference. To fix this, change the mock_request() function to return error pointers and update all the callers to expect that.
