2025-09-05drm/xe/kunit: Introduce xe_pci_fake_data_desc()Michal Wajdeczko
We already use struct xe_pci_fake_data to provide custom config of the fake PCI device and soon we will be using this struct also as direct parameter for the parameterized Xe KUnit tests. Add function to generate description based on that config data. For platform or subplatform name lookup pciidlist which already have definitions of all supported platforms. Examples: TIGERLAKE TIGERLAKE A0 TIGERLAKE SR-IOV PF ... PANTHERLAKE 30.00(Xe3_LPG) 30.00(Xe3_LPM) PANTHERLAKE 30.00(Xe3_LPG) A0 30.00(Xe3_LPM) A0 PANTHERLAKE 30.00(Xe3_LPG) A0 30.00(Xe3_LPM) A0 SR-IOV VF Signed-off-by: Michal Wajdeczko <michal.wajdeczko@intel.com> Cc: Lucas De Marchi <lucas.demarchi@intel.com> Reviewed-by: Lucas De Marchi <lucas.demarchi@intel.com> Link: https://lore.kernel.org/r/20250829171922.572-4-michal.wajdeczko@intel.com

2025-09-05drm/xe/userptr: replace xe_hmm with gpusvmMatthew Auld
Goal here is cut over to gpusvm and remove xe_hmm, relying instead on common code. The core facilities we need are get_pages(), unmap_pages() and free_pages() for a given useptr range, plus a vm level notifier lock, which is now provided by gpusvm. v2: - Reuse the same SVM vm struct we use for full SVM, that way we can use the same lock (Matt B & Himal) v3: - Re-use svm_init/fini for userptr. v4: - Allow building xe without userptr if we are missing DRM_GPUSVM config. (Matt B) - Always make .read_only match xe_vma_read_only() for the ctx. (Dafna) v5: - Fix missing conversion with CONFIG_DRM_XE_USERPTR_INVAL_INJECT v6: - Convert the new user in xe_vm_madise.

This will simplify compiling out the bits that depend on DRM_GPUSVM in a later patch.

2025-09-04thermal: gov_step_wise: Allow cooling level to be reduced earlierRafael J. Wysocki
The current behavior of the Step-wise thermal governor is to increase the cooling level one step at a time after trip point threshold passing by thermal zone temperature until the temperature stops to rise. Then, nothing is done until the temperature decreases below the (possibly updated) trip point threshold, at which point the cooling level is reduced straight to the applicable minimum. While this generally works, it is not in agreement with the throttling logic description comment in step_wise_manage() any more after some relatively recent changes, and in the case of passive cooling, it may lead to undesirable performance oscillations between high and low levels. For this reason, modify the governor's cooling device state selection function, get_target_state(), to reduce cooling by one level even if the temperature is still above the thermal zone threshold, but the temperature has started to fall down. However, ensure that the cooling level will remain above the applicable minimum in that case to pull the zone temperature further down, possibly until it falls below the trip threshold (which may now be equal to the low temperature of the trip). Doing so should help higher performance to be restored earlier in some cases which is desirable especially for passive trip points with relatively high hysteresis values. Signed-off-by: Rafael J.

2025-09-04ACPI: scan: Add Intel CVS ACPI HIDs to acpi_ignore_dep_ids[]Hans de Goede
Some x86/ACPI laptops with MIPI cameras have a INTC10DE or INTC10E0 ACPI device in the _DEP dependency list of the ACPI devices for the camera- sensors (which have flags.honor_deps set). These devices are for an Intel Vision CVS chip for which an out of tree driver is available [1]. The camera sensor works fine without a driver being loaded for this ACPI device on the 2 laptops this was tested on: ThinkPad X1 Carbon Gen 12 (Meteor Lake) ThinkPad X1 2-in-1 Gen 10 (Arrow Lake) For now add these HIDs to acpi_ignore_dep_ids[] so that acpi_dev_ready_for_enumeration() will return true once the other _DEP dependencies are met and an i2c_client for the camera sensor will get instantiated.

Add lane equalization setting for 8.0 GT/s and 32.0 GT/s to enhance link stability and avoid AER Correctable Errors reported on some platforms (eg. SA8775P). 8.0 GT/s, 16.0 GT/s and 32.0 GT/s require the same equalization setting. This setting is programmed into a group of shadow registers, which can be switched to configure equalization for different speeds by writing 00b, 01b and 10b to `RATE_SHADOW_SEL`. Hence, program equalization registers in a loop using link speed as index, so that equalization setting can be programmed for 8.0 GT/s, 16.0 GT/s and 32.0 GT/s.

2025-09-05md: prevent incorrect update of resync/recovery offsetLi Nan
In md_do_sync(), when md_sync_action returns ACTION_FROZEN, subsequent call to md_sync_position() will return MaxSector. This causes 'curr_resync' (and later 'recovery_offset') to be set to MaxSector too, which incorrectly signals that recovery/resync has completed, even though disk data has not actually been updated. To fix this issue, skip updating any offset values when the sync action is FROZEN. The same holds true for IDLE.
