Depending on the variant of silicon, this field may share the same memory space as the lower byte of the system status register (0x10). In these cases, caching the reserved byte and writing it later may effectively reset the device depending on what happened in between the read and write operations. Solve this problem by avoiding any access to this last byte within offending register groups. This method replaces a workaround which attempted to write the reserved byte with up-to-date contents, but left a small window in which updates by the device could have been clobbered. Now that the driver does not touch these reserved bytes, the order in which the device's registers are written no longer matters, and they can be written in their natural order. The new method is also much more generic, and can be more easily extended to new variants of silicon with different register maps. As part of this change, the register read and write functions must be gently updated to support byte access instead of word access.

by Widad Babikar Omar

Hello Dear, I hope this message finds you well, and let me extend my warmest wishes for a joyful, healthy, and prosperous 2025. My name is Widad Babikar Omar, and a politician/investor from Sudan. For some time now, I’ve been looking for a trustworthy individual or a company to guide me in placing a huge private investment funds into strong, growing business environments — and your region truly stood out to me as full of potential and a viable option. I’m interested in exploring a discreet, long-term investment opportunities outside of Sudan in any of these key sectors due to my background: - Real estate and Construction - Oil & Gas - Renewable energy - Manufacturing and Mining - Healthcare - Tech & innovation - Education and Agriculture My goal is to build a partnership based on trust, clarity, and mutual benefit. If you’re open to a conversation, I’d be glad to share more details and discuss how we might work together. Thank you for considering this opportunity. I understand this might be a significant decision, and I’ll fully respect whatever response you choose to give. Looking forward to hearing from you soon. Warm regards, Widad Babikar Omar

[PATCH] arm64: dts: rockchip: Remove workaround that prevented Turing RK1 GPU power regulator control

by Sam Edwards

The RK3588 GPU power domain cannot be activated unless the external power regulator is already on. When GPU support was added to this DT, we had no way to represent this requirement, so `regulator-always-on` was added to the `vdd_gpu_s0` regulator in order to ensure stability. A later patch series (see "Fixes:" commit) resolved this shortcoming, but that commit left the workaround -- and rendered the comment above it no longer correct. Remove the workaround to allow the GPU power regulator to power off, now that the DT includes the necessary information to power it back on correctly.

+ mm-fix-copy_vma-error-handling-for-hugetlb-mappings.patch added to mm-hotfixes-unstable branch

by Andrew Morton

The patch titled Subject: mm: fix copy_vma() error handling for hugetlb mappings has been added to the -mm mm-hotfixes-unstable branch. Its filename is mm-fix-copy_vma-error-handling-for-hugetlb-mappings.patch This patch will shortly appear at https://git.kernel.org/pub/scm/linux/kernel/git/akpm/25-new.git/tree/patche… This patch will later appear in the mm-hotfixes-unstable branch at git://git.kernel.org/pub/scm/linux/kernel/git/akpm/mm Before you just go and hit "reply", please: a) Consider who else should be cc'ed b) Prefer to cc a suitable mailing list as well c) Ideally: find the original patch on the mailing list and do a reply-to-all to that, adding suitable additional cc's *** Remember to use Documentation/process/submit-checklist.rst when testing your code *** The -mm tree is included into linux-next via the mm-everything branch at git://git.kernel.org/pub/scm/linux/kernel/git/akpm/mm and is updated there every 2-3 working days ------------------------------------------------------ From: Ricardo Ca��uelo Navarro <rcn(a)igalia.com> Subject: mm: fix copy_vma() error handling for hugetlb mappings Date: Fri, 23 May 2025 14:19:10 +0200 If, during a mremap() operation for a hugetlb-backed memory mapping, copy_vma() fails after the source vma has been duplicated and opened (ie. vma_link() fails), the error is handled by closing the new vma. This updates the hugetlbfs reservation counter of the reservation map which at this point is referenced by both the source vma and the new copy. As a result, once the new vma has been freed and copy_vma() returns, the reservation counter for the source vma will be incorrect. This patch addresses this corner case by clearing the hugetlb private page reservation reference for the new vma and decrementing the reference before closing the vma, so that vma_close() won't update the reservation counter. This is also what copy_vma_and_data() does with the source vma if copy_vma() succeeds, so a helper function has been added to do the fixup in both functions. The issue was reported by a private syzbot instance and can be reproduced using the C reproducer in [1]. It's also a possible duplicate of public syzbot report [2].

This happens usually when the cgroup has MANY processes and memory.oom.group is set. Example I am seeing in real production: [462012.244552] Memory cgroup out of memory: Killed process 3370438 (crosvm) .... .... [462037.318059] Memory cgroup out of memory: Killed process 4171372 (adb) .... [462037.348314] watchdog: BUG: soft lockup - CPU#64 stuck for 26s! [stat_manager-ag:1618982] .... Quick look at why this is so slow, it seems to be related to serial flush for certain machine types. For all the crashes I saw, the target CPU was at console_flush_all(). In the case above, there are thousands of processes in the cgroup, and it is soft locking up before it reaches the 1024 limit in the code (which would call the cond_resched()). So, cond_resched() in 1024 blocks is not sufficient. Remove the counter-based conditional rescheduling logic and call cond_resched() unconditionally after each task iteration, after fn() is called. This avoids the lockup independently of how slow fn() is.

[PATCH v2 1/1] x86/fred/signal: Prevent single-step upon ERETU completion

by Xin Li (Intel)

From: Xin Li <xin(a)zytor.com> Clear the software event flag in the augmented SS to prevent infinite SIGTRAP handler loop if TF is used without an external debugger. Following is a typical single-stepping flow for a user process: 1) The user process is prepared for single-stepping by setting RFLAGS.TF = 1. 2) When any instruction in user space completes, a #DB is triggered. 3) The kernel handles the #DB and returns to user space, invoking the SIGTRAP handler with RFLAGS.TF = 0. 4) After the SIGTRAP handler finishes, the user process performs a sigreturn syscall, restoring the original state, including RFLAGS.TF = 1. 5) Goto step 2. According to the FRED specification: A) Bit 17 in the augmented SS is designated as the software event flag, which is set to 1 for FRED event delivery of SYSCALL, SYSENTER, or INT n. B) If bit 17 of the augmented SS is 1 and ERETU would result in RFLAGS.TF = 1, a single-step trap will be pending upon completion of ERETU. In step 4) above, the software event flag is set upon the sigreturn syscall, and its corresponding ERETU would restore RFLAGS.TF = 1. This combination causes a pending single-step trap upon completion of ERETU. Therefore, another #DB is triggered before any user space instruction is executed, which leads to an infinite loop in which the SIGTRAP handler keeps being invoked on the same user space IP.

[PATCH v2] iio: common: st_sensors: Fix use of uninitialize device structs

by Maud Spierings via B4 Relay

From: Maud Spierings <maudspierings(a)gocontroll.com> Throughout the various probe functions &indio_dev->dev is used before it is initialized. This caused a kernel panic in st_sensors_power_enable when the call to devm_regulator_bulk_get_enable() fails and then calls dev_err_probe() with the uninitialized device. This seems to only cause a panic with dev_err_probe(), dev_err, dev_warn and dev_info don't seem to cause a panic, but are fixed as well. Signed-off-by: Maud Spierings <maudspierings(a)gocontroll.com> --- When I search for general &indio_dev->dev usage, I see quite a lot more hits, but I am not sure if there are issues with those too. This issue has existed for a long time it seems and therefore it is nearly impossible to find a proper fixes tag. I would love to see it at least backported to 6.12 as that is where I encountered it, and I believe the patch should apply without conflicts. The investigation into this issue can be found in this thread [1] [1]: https://lore.kernel.org/all/AM7P189MB100986A83D2F28AF3FFAF976E39EA@AM7P189M… --- Changes in v2: - Added SoB in commit message - Link to v1: https://lore.kernel.org/r/20250522-st_iio_fix-v1-1-d689b35f1612@gocontroll.… --- drivers/iio/accel/st_accel_core.c | 10 +++---- drivers/iio/common/st_sensors/st_sensors_core.c | 35 +++++++++++----------- drivers/iio/common/st_sensors/st_sensors_trigger.c | 18 +++++------ 3 files changed, 31 insertions(+), 32 deletions(-) diff --git a/drivers/iio/accel/st_accel_core.c b/drivers/iio/accel/st_accel_core.c index 99cb661fabb2d9cc1943fa8d0a6f3becb71126e6..a7961c610ed203d039bbf298c8883031a578fb0b 100644 --- a/drivers/iio/accel/st_accel_core.c +++ b/drivers/iio/accel/st_accel_core.c @@ -1353,6 +1353,7 @@ static int apply_acpi_orientation(struct iio_dev *indio_dev) union acpi_object *ont;

[PATCH v2 1/1] Drivers: hv: Always select CONFIG_SYSFB for Hyper-V guests

by mhkelley58＠gmail.com

From: Michael Kelley <mhklinux(a)outlook.com> The Hyper-V host provides guest VMs with a range of MMIO addresses that guest VMBus drivers can use. The VMBus driver in Linux manages that MMIO space, and allocates portions to drivers upon request. As part of managing that MMIO space in a Generation 2 VM, the VMBus driver must reserve the portion of the MMIO space that Hyper-V has designated for the synthetic frame buffer, and not allocate this space to VMBus drivers other than graphics framebuffer drivers. The synthetic frame buffer MMIO area is described by the screen_info data structure that is passed to the Linux kernel at boot time, so the VMBus driver must access screen_info for Generation 2 VMs. (In Generation 1 VMs, the framebuffer MMIO space is communicated to the guest via a PCI pseudo-device, and access to screen_info is not needed.) In commit a07b50d80ab6 ("hyperv: avoid dependency on screen_info") the VMBus driver's access to screen_info is restricted to when CONFIG_SYSFB is enabled. CONFIG_SYSFB is typically enabled in kernels built for Hyper-V by virtue of having at least one of CONFIG_FB_EFI, CONFIG_FB_VESA, or CONFIG_SYSFB_SIMPLEFB enabled, so the restriction doesn't usually affect anything. But it's valid to have none of these enabled, in which case CONFIG_SYSFB is not enabled, and the VMBus driver is unable to properly reserve the framebuffer MMIO space for graphics framebuffer drivers. The framebuffer MMIO space may be assigned to some other VMBus driver, with undefined results. As an example, if a VM is using a PCI pass-thru NVMe controller to host the OS disk, the PCI NVMe controller is probed before any graphics devices, and the NVMe controller is assigned a portion of the framebuffer MMIO space. Hyper-V reports an error to Linux during the probe, and the OS disk fails to get setup. Then Linux fails to boot in the VM. Fix this by having CONFIG_HYPERV always select SYSFB. Then the VMBus driver in a Gen 2 VM can always reserve the MMIO space for the graphics framebuffer driver, and prevent the undefined behavior. But don't select SYSFB when building for HYPERV_VTL_MODE as VTLs other than VTL 0 don't have a framebuffer and aren't subject to the issue. Adding SYSFB in such cases is harmless, but would increase the image size for no purpose.
