2025-02-12drm/xe: Carve out wopcm portion from the stolen memoryNirmoy Das
The top of stolen memory is WOPCM, which shouldn't be accessed. Remove this portion from the stolen memory region for discrete platforms. This was already done for integrated, but was missing for discrete platforms. This also moves get_wopcm_size() so detect_bar2_dgfx() and detect_bar2_integrated can use the same function. v2: Improve commit message and suitable stable version tag(Lucas) Fixes: d8b52a02cb40 ("drm/xe: Implement stolen memory.")

2025-02-12drm/v3d: Add clock handlingStefan Wahren
Since the initial commit 57692c94dcbe ("drm/v3d: Introduce a new DRM driver for Broadcom V3D V3.x+") the struct v3d_dev reserved a pointer for an optional V3D clock. But there wasn't any code, which fetched it. So add the missing clock handling before accessing any V3D registers.

2025-02-12platform/x86: thinkpad_acpi: Fix registration of tpacpi platform driverMark Pearson
The recent platform profile changes prevent the tpacpi platform driver from registering. This error is seen in the kernel logs, and the various tpacpi entries are not created: [ 7550.642171] platform thinkpad_acpi: Resources present before probing This happens because devm_platform_profile_register() is called before tpacpi_pdev probes (thanks to Kurt Borja for identifying the root cause). For now revert back to the old platform_profile_register to fix the issue. This is quick fix and will be re-implemented later as more testing is needed for full solution. Tested on X1 Carbon G12.

2025-02-12drm/sched: Use struct for drm_sched_init() paramsPhilipp Stanner
drm_sched_init() has a great many parameters and upcoming new functionality for the scheduler might add even more. Generally, the great number of parameters reduces readability and has already caused one missnaming, addressed in: commit 6f1cacf4eba7 ("drm/nouveau: Improve variable name in nouveau_sched_init()"). Introduce a new struct for the scheduler init parameters and port all users.

Convert most mutex_(un)lock calls to use (scoped_)guard instead. This generally reduces line count and prevents bugs like forgetting to unlock the mutex. I've left traditional calls in a few places where scoped helpers would be more verbose. This mostly happens where debugfs_file_put needs to be called regardless.

2025-02-11s390/cio: Fix CHPID "configure" attribute cachingPeter Oberparleiter
In some environments, the SCLP firmware interface used to query a CHPID's configured state is not supported. On these environments, rapidly reading the corresponding sysfs attribute produces inconsistent results: $ cat /sys/devices/css0/chp0.00/configure cat: /sys/devices/css0/chp0.00/configure: Operation not supported $ cat /sys/devices/css0/chp0.00/configure 3 This occurs for example when Linux is run as a KVM guest. The inconsistency is a result of CIO using cached results for generating the value of the "configure" attribute while failing to handle the situation where no data was returned by SCLP. Fix this by not updating the cache-expiration timestamp when SCLP returns no data. With the fix applied, the system response is consistent: $ cat /sys/devices/css0/chp0.00/configure cat: /sys/devices/css0/chp0.00/configure: Operation not supported $ cat /sys/devices/css0/chp0.00/configure cat: /sys/devices/css0/chp0.00/configure: Operation not supported Reviewed-by: Vineeth Vijayan <vneethv@linux.ibm.com> Reviewed-by: Eric Farman <farman@linux.ibm.com> Tested-by: Eric Farman <farman@linux.ibm.com> Signed-off-by: Peter Oberparleiter <oberpar@linux.ibm.com> Signed-off-by: Vasily Gorbik <gor@linux.ibm.com>
2025-02-11drm/edp-panel: Add panel used by T14s Gen6 SnapdragonSebastian Reichel
The Lenovo Thinkpad T14s Gen6 Snapdragon is currently sold with three different panel versions: OLED, Low Power IPS or IPS with Touchscreen. My Low Power IPS version had this panel and the kernel complained about not knowing any details. I don't have any panel documentation, but as far as I can see the same timings for the already supported CSO panel also work for this one.

The DT bindings for ov7251 specify "enable" GPIO (xshutdown in documentation) but the int3472 indiscriminately provides this as a "reset" GPIO to sensor drivers.

2025-02-11igc: Fix HW RX timestamp when passed by ZC XDPZdenek Bouska
Fixes HW RX timestamp in the following scenario: - AF_PACKET socket with enabled HW RX timestamps is created - AF_XDP socket with enabled zero copy is created - frame is forwarded to the BPF program, where the timestamp should still be readable (extracted by igc_xdp_rx_timestamp(), kfunc behind bpf_xdp_metadata_rx_timestamp()) - the frame got XDP_PASS from BPF program, redirecting to the stack - AF_PACKET socket receives the frame with HW RX timestamp Moves the skb timestamp setting from igc_dispatch_skb_zc() to igc_construct_skb_zc() so that igc_construct_skb_zc() is similar to igc_construct_skb(). This issue can also be reproduced by running: # tools/testing/selftests/bpf/xdp_hw_metadata enp1s0 When a frame with the wrong port 9092 (instead of 9091) is used: # echo -n xdp | nc -u -q1 192.168.10.9 9092 then the RX timestamp is missing and xdp_hw_metadata prints: skb hwtstamp is not found!

2025-02-11idpf: call set_real_num_queues in idpf_openJoshua Hay
On initial driver load, alloc_etherdev_mqs is called with whatever max queue values are provided by the control plane. However, if the driver is loaded on a system where num_online_cpus() returns less than the max queues, the netdev will think there are more queues than are actually available. Only num_online_cpus() will be allocated, but skb_get_queue_mapping(skb) could possibly return an index beyond the range of allocated queues. Consequently, the packet is silently dropped and it appears as if TX is broken. Set the real number of queues during open so the netdev knows how many queues will be allocated.

This reverts commit cd7a38c40b231350a3cd0fd774f4e6bb68c4b411. When submitting the change above, it was thought that the origin of the init_data should be a clear choice, from the driver or from DT but not both. It turns out some devices, such as qcom-msm8974-lge-nexus5-hammerhead, relied on the old behaviour to override the init_data provided by the driver, making it some kind of default if none is provided by the platform. Using the init_data provided by the driver when it is present broke these devices so revert the change to fixup the situation and add a comment to make things a bit more clear Reported-by: Luca Weiss <luca@lucaweiss.eu> Closes: https://lore.kernel.org/lkml/5857103.DvuYhMxLoT@lucaweiss.eu Fixes: cd7a38c40b23 ("regulator: core: do not silently ignore provided init_data") Signed-off-by: Jerome Brunet <jbrunet@baylibre.com> Link: https://patch.msgid.link/20250211-regulator-init-data-fixup-v1-1-5ce1c6cff990@baylibre.com Signed-off-by: Mark Brown <broonie@kernel.org>

2025-02-11mfd: syscon: Restore device_node_to_regmap() for non-syscon nodesRob Herring (Arm)
Commit ba5095ebbc7a ("mfd: syscon: Allow syscon nodes without a "syscon" compatible") broke drivers which call device_node_to_regmap() on nodes without a "syscon" compatible. Restore the prior behavior for device_node_to_regmap(). This also makes using device_node_to_regmap() incompatible with of_syscon_register_regmap() again, so add kerneldoc for device_node_to_regmap() and syscon_node_to_regmap() to make it clear how and when each one should be used.

The top of stolen memory is WOPCM, which shouldn't be accessed. Remove this portion from the stolen memory region for discrete platforms. This was already done for integrated, but was missing for discrete platforms. This also moves get_wopcm_size() so detect_bar2_dgfx() and detect_bar2_integrated can use the same function. v2: Improve commit message and suitable stable version tag(Lucas) Fixes: d8b52a02cb40 ("drm/xe: Implement stolen memory.")
