[REGRESSION][stable v6.14] AMD GPU init failure in v6.14.10 – revert needed for commit c53f23f7075c9f63f14d7ec8f2cc3e33e118d986

by msk

Hi all, #regzbot introduced: c53f23f7075c9f63f14d7ec8f2cc3e33e118d986 **Summary** A regression introduced in **v6.14.10** breaks AMD GPU initialization on RX 9070 XT system due to commit c53f23f7… (“drm/amd/display: check stream id dml21 wrapper…”). Reverting this commit restores proper graphical startup. dmesg output before revert [ 2.699091] ACPI: bus type drm_connector registered [ 2.699734] xhci_hcd 0000:02:00.0: xHCI Host Controller [ 2.699740] xhci_hcd 0000:02:00.0: new USB bus registered, assigned bus number 1 [ 2.755165] xhci_hcd 0000:02:00.0: hcc params 0x0200ef81 hci version 0x110 quirks 0x0000000000000010 [ 2.755445] xhci_hcd 0000:02:00.0: xHCI Host Controller [ 2.755448] xhci_hcd 0000:02:00.0: new USB bus registered, assigned bus number 2 [ 2.755450] xhci_hcd 0000:02:00.0: Host supports USB 3.1 Enhanced SuperSpeed [ 2.755511] usb usb1: New USB device found, idVendor=1d6b, idProduct=0002, bcdDevice= 6.14 [ 2.755512] usb usb1: New USB device strings: Mfr=3, Product=2, SerialNumber=1 [ 2.755514] usb usb1: Product: xHCI Host Controller [ 2.755515] usb usb1: Manufacturer: Linux 6.14.10-x64v3-xanmod1 xhci-hcd [ 2.755517] usb usb1: SerialNumber: 0000:02:00.0 [ 2.755613] hub 1-0:1.0: USB hub found [ 2.755629] hub 1-0:1.0: 10 ports detected [ 2.755952] usb usb2: We don't know the algorithms for LPM for this host, disabling LPM.

However, upon reviewing the commits, there is no indication that it is a downstream issue. I attempted to confirm this regression by building the kernel from the Git repository, but my limited skills and knowledge proved insufficient. Please review this regression and consider reverting the commit from the stable 6.14 and 6.15 branches - or propose an alternate patch. Thanks & Regards, Marcin Kryzak

[PATCH] HID: lenovo: Restrict F7/9/11 mode to compact keyboards only

by Iusico Maxim

Commit 2f2bd7cbd1d1 ("hid: lenovo: Resend all settings on reset_resume for compact keyboards") introduced a regression for ThinkPad TrackPoint Keyboard II by removing the conditional check for enabling F7/9/11 mode needed for compact keyboards only. As a result, the non-compact keyboards can no longer toggle Fn-lock via Fn+Esc, although it can be controlled via sysfs knob that directly sends raw commands. This patch restores the previous conditional check without any additions.

[PATCH v2] tools/resolve_btfids: Fix build when cross compiling kernel with clang.

by Suleiman Souhlal

When cross compiling the kernel with clang, we need to override CLANG_CROSS_FLAGS when preparing the step libraries. Prior to commit d1d096312176 ("tools: fix annoying "mkdir -p ..." logs when building tools in parallel"), MAKEFLAGS would have been set to a value that wouldn't set a value for CLANG_CROSS_FLAGS, hiding the fact that we weren't properly overriding it.

[PATCH v4 01/10] platform/x86/intel/pmt: fix a crashlog NULL pointer access

Usage of the intel_pmt_read() for binary sysfs, requires a pcidev. The current use of the endpoint value is only valid for telemetry endpoint usage.

The AXI PWMGEN IP block has a compile option ASYNC_CLK_EN that allows the use of an external clock for the PWM output separate from the AXI clock that runs the peripheral. This was missed in the original bindings and so users were writing dts files where the one and only clock specified would be the external clock, if there was one, incorrectly missing the separate AXI clock. The correct bindings are that the AXI clock is always required and the external clock is optional (must be given only when HDL compile option ASYNC_CLK_EN=1).

[PATCH] sched: Fix preemption string of preempt_dynamic_none

by Thomas Weißschuh

Zero is a valid value for "preempt_dynamic_mode", namely "preempt_dynamic_none". Fix the off-by-one in preempt_model_str(), so that "preempty_dynamic_none" is correctly formatted as PREEMPT(none) instead of PREEMPT(undef).
