Stacktrace looks different. Anyway, are you maybe able to verify if the issue is still reproducible with latest v6.6-rt stable (v6.6.78-rt51 at the time of writing)? Looks like you are on v6.6-rt, thus the question. Thanks, Juri

[PATCH v4 0/7] KVM: arm64: PMU: Fix SET_ONE_REG for vPMC regs

by Akihiko Odaki

Prepare vPMC registers for user-initiated changes after first run. This is important specifically for debugging Windows on QEMU with GDB; QEMU tries to write back all visible registers when resuming the VM execution with GDB, corrupting the PMU state. Windows always uses the PMU so this can cause adverse effects on that particular OS. This series also contains patch "KVM: arm64: PMU: Set raw values from user to PM{C,I}NTEN{SET,CLR}, PMOVS{SET,CLR}", which reverts semantic changes made for the mentioned registers in the past. It is necessary to migrate the PMU state properly on Firecracker, QEMU, and crosvm. Signed-off-by: Akihiko Odaki <akihiko.odaki(a)daynix.com> --- Changes in v4: - Reverted changes for functions implementing ioctls in patch "KVM: arm64: PMU: Assume PMU presence in pmu-emul.c". - Removed kvm_pmu_vcpu_reset(). - Reordered function calls in kvm_vcpu_reload_pmu() for better style. - Link to v3: https://lore.kernel.org/r/20250312-pmc-v3-0-0411cab5dc3d@daynix.com Changes in v3: - Added patch "KVM: arm64: PMU: Assume PMU presence in pmu-emul.c". - Added an explanation of this path series' motivation to each patch. - Explained why userspace register writes and register reset should be covered in patch "KVM: arm64: PMU: Reload when user modifies registers". - Marked patch "KVM: arm64: PMU: Set raw values from user to PM{C,I}NTEN{SET,CLR}, PMOVS{SET,CLR}" for stable. - Reoreded so that patch "KVM: arm64: PMU: Set raw values from user to PM{C,I}NTEN{SET,CLR}, PMOVS{SET,CLR}" would come first. - Added patch "KVM: arm64: PMU: Call kvm_pmu_handle_pmcr() after masking PMCNTENSET_EL0". - Added patch "KVM: arm64: Reload PMCNTENSET_EL0". - Link to v2: https://lore.kernel.org/r/20250307-pmc-v2-0-6c3375a5f1e4@daynix.com Changes in v2: - Changed to utilize KVM_REQ_RELOAD_PMU as suggested by Oliver Upton. - Added patch "KVM: arm64: PMU: Reload when user modifies registers" to cover more registers. - Added patch "KVM: arm64: PMU: Set raw values from user to PM{C,I}NTEN{SET,CLR}, PMOVS{SET,CLR}". - Link to v1: https://lore.kernel.org/r/20250302-pmc-v1-1-caff989093dc@daynix.com --- Akihiko Odaki (7): KVM: arm64: PMU: Set raw values from user to PM{C,I}NTEN{SET,CLR}, PMOVS{SET,CLR} KVM: arm64: PMU: Assume PMU presence in pmu-emul.c KVM: arm64: PMU: Fix SET_ONE_REG for vPMC regs KVM: arm64: PMU: Reload when user modifies registers KVM: arm64: PMU: Call kvm_pmu_handle_pmcr() after masking PMCNTENSET_EL0 KVM: arm64: PMU: Reload PMCNTENSET_EL0 KVM: arm64: PMU: Reload when resetting arch/arm64/kvm/arm.c | 8 ++++--- arch/arm64/kvm/pmu-emul.c | 60 ++++++++++++++--------------------------------- arch/arm64/kvm/reset.c | 3 --- arch/arm64/kvm/sys_regs.c | 53 +++++++++++++++++++++++------------------ include/kvm/arm_pmu.h | 3 +-- 5 files changed, 53 insertions(+), 74 deletions(-) --- base-commit: da2f480cb24d39d480b1e235eda0dd2d01f8765b change-id: 20250302-pmc-b90a86af945c Best regards, -- Akihiko Odaki <akihiko.odaki(a)daynix.com>

[PATCH v3] KVM: PPC: Enable CAP_SPAPR_TCE_VFIO on pSeries KVM guests

by Amit Machhiwal

Currently on book3s-hv, the capability KVM_CAP_SPAPR_TCE_VFIO is only available for KVM Guests running on PowerNV and not for the KVM guests running on pSeries hypervisors. This prevents a pSeries L2 guest from leveraging the in-kernel acceleration for H_PUT_TCE_INDIRECT and H_STUFF_TCE hcalls that results in slow startup times for large memory guests. Support for VFIO on pSeries was restored in commit f431a8cde7f1 ("powerpc/iommu: Reimplement the iommu_table_group_ops for pSeries"), making it possible to re-enable this capability on pSeries hosts. This change enables KVM_CAP_SPAPR_TCE_VFIO for nested PAPR guests on pSeries, while maintaining the existing behavior on PowerNV. Booting an L2 guest with 128GB of memory shows an average 11% improvement in startup time.

[PATCH 5.10.y 5.15.y] ptp: Ensure info->enable callback is always set

by Abdelkareem Abdelsaamad

From: Thomas Weißschuh <linux(a)weissschuh.net> commit fd53aa40e65f518453115b6f56183b0c201db26b upstream. The ioctl and sysfs handlers unconditionally call the ->enable callback. Not all drivers implement that callback, leading to NULL dereferences. Example of affected drivers: ptp_s390.c, ptp_vclock.c and ptp_mock.c. Instead use a dummy callback if no better was specified by the driver. Fixes: d94ba80ebbea ("ptp: Added a brand new class driver for ptp clocks.")

[PATCH 6.6.y 0/2] wifi: rtw89: RTL8852BE: Fix the shutdown issue

by Zenm Chen

This patch series addresses a shutdown issue reported in [1]. This problem has been fixed on kernel 6.12 and later, kernel 6.6 is the last kernel these upstream patches should go to because the Realtek RTL8852BE chip supported by kernel since v6.2 is the only chip known to have this problem.

[PATCH v4 0/7] drm/v3d: Fix GPU reset issues on the Raspberry Pi 5

by Maíra Canal

This series addresses GPU reset issues reported in [1], where running a long compute job would trigger repeated GPU resets, leading to a UI freeze. Patches #1 and #2 prevent the same faulty job from being resubmitted in a loop, mitigating the first cause of the issue. However, the issue isn't entirely solved. Even with only a single GPU reset, the UI still freezes on the Raspberry Pi 5, indicating a GPU hang. Patches #3 to #6 address this by properly configuring the V3D_SMS registers, which are required for power management and resets in V3D 7.1. Patch #7 updates the DT maintainership, replacing Emma with the current v3d driver maintainer.
