Hello, everyone In the context of ubiquitous intelligent computing, the latency observation capability of the operating system is particularly important, especially for identifying severe business failures caused by occasional high-latency issues, which are difficult to locate. Addressing the shortcomings of existing latency observation methods, such as getdelays, which can only be used to view average latency and does not record abnormal latency peaks, making it difficult to identify abnormal latency situations, I have some thoughts and contributions in the Linux Kernel regarding this point. Here are some of my contributions : 1) delaytop contributions Delaytop is used to observe system-wide latency top-n tasks, which helps in locating latency-related system performance issues. [1][2] 2) latency-related contributions I’ve also contributed to latency monitoring in the past (e.g., max latency patches), showing a continued interest in this area. [3][4] PS: The list of files/directories I want to maintain is as follows: Documentation/accounting/delay-accounting.rst tools/accounting/* The related patches are as follows: [1] https://lore.kernel.org/all/20250619211843633h05gWrBDMFkEH6xAVm_5y@zte.com.… [2] https://lore.kernel.org/all/20250710135451340_5pOgpIFi0M5AE7H44W1D@zte.com.… [3] https://lore.kernel.org/all/20241203164848805CS62CQPQWG9GLdQj2_BxS@zte.com.… [4] https://lore.kernel.org/all/20241220173105906EOdsPhzjMLYNJJBqgz1ga@zte.com.… My solution has been recognized and merged into the mainline Linux kernel, and I am currently serving as the maintainer of the getdelays in the Linux kernel. I would like to formally apply for the maintainer role of this module within the Anolis community as well. In this capacity, I aim to further enhance the latency monitoring capabilities, synchronize the latest upstream code, participate in code reviews, and contribute to the sustained development of this module within the Anolis ecosystem. Thanks Yaxin

[PATCH] drm/amd/display: Remove wrong signal from vrr calculation

by Cryolitia PukNgae

commit bcebe44f6bb6d9a85e0710d0086bc3956e6887ba upstream. In some of the merge conflict fixes, one '+' was accidentally left at the beginning of the line. Fortunately, this did not cause any major issues since it acted as a number signal. This commit addresses this issue by removing the extra '+'.

Add myself as co-maintainer for x86 architecture

by mapicccy

Hi all: This email proposes adding myself as a co-maintainer for the x86 architecture in the cloud-kernel maintained in the openAnolis. Over the last three years, I've deeply engaged with the x86 architecture, making some contributions across various aspects. That includes: New feature: Enable hwdrc through resctrl[1] New feature: Alicc (Alibaba cryptographic accelerator driver)[2][3][4] Backport feature: support microcode hot-rollback on intel platform[5] Backport feature: Enable ACPI PCC on arm64[6] Backport feature:perf support instruction latency\L2 Topdown events\data block and addr block.etc.[7] Other bug fixes:[8][9][10][11][12][13][14][15][16][17][18][19][20] Giving that I have been an x86 architecture reviewer for over a year, I’d like to take on greater responsibilities. And in the future, I will continuously focus on x86 architecture and make more efforts based on the openAnolis community. Thanks, Guanjun PS: The files(or directories) list that I want to maintain is as follows: drivers/iommu/intel-iommu.c include/linux/intel-iommu.h drivers/iommu/ include/linux/iommu.h include/linux/of_iommu.h include/linux/iova.h Documentation/x86/resctrl* arch/x86/include/asm/resctrl.h arch/x86/kernel/cpu/resctrl/ Documentation/devicetree/bindings/x86/ Documentation/x86/ arch/x86/ drivers/dma/ Documentation/admin-guide/pm/cpuidle.rst Documentation/driver-api/pm/cpuidle.rst drivers/cpuidle/ include/linux/cpuidle.h [1] https://gitee.com/anolis/cloud-kernel/pulls/2643 [2] https://gitee.com/anolis/cloud-kernel/pulls/611 [3] https://gitee.com/anolis/cloud-kernel/pulls/606 [4] https://gitee.com/anolis/cloud-kernel/pulls/573 [5] https://gitee.com/anolis/cloud-kernel/pulls/383 [6] https://gitee.com/anolis/cloud-kernel/pulls/679 [7] https://gitee.com/anolis/cloud-kernel/pulls/324 [8] https://gitee.com/anolis/cloud-kernel/pulls/2643 [9] https://gitee.com/anolis/cloud-kernel/pulls/1887 [10] https://gitee.com/anolis/cloud-kernel/pulls/896 [11] https://gitee.com/anolis/cloud-kernel/pulls/701 [12] https://gitee.com/anolis/cloud-kernel/pulls/690 [13] https://gitee.com/anolis/cloud-kernel/pulls/619 [14] https://gitee.com/anolis/cloud-kernel/pulls/617 [15] https://gitee.com/anolis/cloud-kernel/pulls/543 [16] https://gitee.com/anolis/cloud-kernel/pulls/472 [17] https://gitee.com/anolis/cloud-kernel/pulls/426 [18] https://gitee.com/anolis/cloud-kernel/pulls/292 [19] https://gitee.com/anolis/cloud-kernel/pulls/211 [20] https://gitee.com/anolis/cloud-kernel/pulls/24

Remove myself and Tony from the networking maintainers and add D.Wythe as the maintainer

by Dust Li

Hi all, Currently Tony and I are no longer focusing on maintain the networking stack, it is no longer proper for us to be as the maintainer. D.Wythe has showed his deep understanding in TCP and SMC in the last 2 years, he will take the responsability to dedicate his effort in maintaining the networking stack on ANCK. So remove myself and Tony as the maintainer and add D.Wythe as the maintainer of general networking stack. Hope XuanZhuo and D.Wythe continue to work together to make ANCK networking better ! Best regards, Dust
