The policy calls for implementing documented contracts, respecting macOS layering, labeling undocumented quirks, and avoiding leaked or restricted Apple material and disassembly-derived matching code. The excerpt reports that AI-generated patches got the macOS version of League of Legends running on Linux, AI-focused forks are seeking to merge patches upstream, and initial ARM64 support has been introduced. ### Source excerpt Darling is the software project more than a decade in development that is designed to run macOS binaries on Linux. This macOS compatibility layer for Linux is now gaining more brisk developments as it turns to AI/LLMs to assist in this creation... ## ChaCha AVX-512 Optimization For Linux 7.5 Yields Up To 99% Improvement On AMD Zen 5 DevFeed: [ChaCha AVX-512 Optimization For Linux 7.5 Yields Up To 99% Improvement On AMD Zen 5]() Original publisher: [Read original article]() Author: Michael Larabel Published: 2026-11-09T12:35:12Z Content type: news Language: en Sources: [Phoronix]() Topics: [ChaCha](), [Linux Kernel]() Tags: [ai](), [amd](), [avx](), [code](), [desktop-linux](), [halo](), [improvement](), [linux](), [linux-benchmarking](), [linux-hardware-benchmarks](), [linux-hardware-reviews](), [linux-how-to](), [linux-performance](), [linux-server-benchmarks](), [open-source-graphics](), [optimization](), [performance](), [phoronix](), [phoronix-test-suite](), [processors](), [ubuntu-benchmarks](), [ubuntu-hardware](), [zen-5]() ### AI overview A new 16-block AVX-512 ChaCha function in Linux libcrypto can improve bulk encryption performance on recent processors. The existing AVX-512VL path handles up to 8 blocks using 256-bit registers; the patch adds a 512-bit path for inputs larger than 8 blocks, gated by X86_FEATURE_PREFER_YMM. The excerpt reports up to 99% improvement on AMD Zen 5 with the full 512-bit data path and up to 39% on Zen 4 using its 256-bit data path. The change is queued in Eric Biggers' libcrypto-next branch and was expected to be submitted for the Linux 7.5 merge window. ### Source excerpt The Linux kernel's ChaCha symmetric stream cipher code has long had an AVX-512 optimized code path but it was catering to the early generations of Intel CPUs with AVX-512 (Skylake) that suffered from down-clocking under use. But now slated for arrival with Linux 7.5 is tuning the code to perform better on today's AVX-512 Intel and AMD processors that don't suffer from this limitation. In turn the ChaCha performance is as much as 99% faster with current-generation AMD Zen 5 processors... ## Linux Seeing Driver Work For MSI Mystic Light On Latest Ryzen Motherboards DevFeed: [Linux Seeing Driver Work For MSI Mystic Light On Latest Ryzen Motherboards]() Original publisher: [Read original article]() Author: Michael Larabel Published: 2026-11-09T11:20:49Z Content type: news Language: en Sources: [Phoronix]() Topics: [Linux Kernel](), [Linux]() Tags: [chip](), [controller](), [core](), [cpu](), [desktop-linux](), [driver](), [i-o](), [kernel](), [lighting](), [linux](), [linux-benchmarking](), [linux-hardware-benchmarks](), [linux-hardware-reviews](), [linux-how-to](), [linux-performance](), [linux-server-benchmarks](), [misc](), [motherboard](), [msi](), [open](), [open-source](), [open-source-graphics](), [phoronix](), [phoronix-test-suite](), [rails](), [rgb](), [sensors](), [ubuntu-benchmarks](), [ubuntu-hardware](), [usb]() ### AI overview Initial Linux driver patches for MSI Mystic Light focus on exposing voltage readings, rather than RGB controls. On tested motherboards, the USB microcontroller monitors the CPU 1P8, CHIP Core, and VDD MISC rails, which the Super I/O chip does not monitor.

The feature currently works only on Gfx12.5 hardware and requires the HuC micro-controller firmware to be loaded. The excerpt notes Intel's greater investment in its VA-API media driver paired with oneVPL, and says broader support on newer Xe2 and Xe3 hardware is hoped for; it does not establish that support is available there. ### Source excerpt Hyunjun Ko of Igalia continues working on enhancing the Vulkan Video support in the Mesa ANV driver for better open-source video acceleration support... ## Linux 7.4-rc2 Released With FAT32 Optimization, AMDGPU HDMI 2.2 Improvement DevFeed: [Linux 7.4-rc2 Released With FAT32 Optimization, AMDGPU HDMI 2.2 Improvement]() Original publisher: [Read original article]() Author: Michael Larabel Published: 2026-11-09T00:48:19Z Content type: news Language: en Sources: [Phoronix]() Topics: [Linux](), [mount]() Tags: [2-2](), [7-4](), [ai](), [amd](), [announcement](), [automated](), [bug](), [bug-fixes](), [bug-reports](), [bugs](), [changes](), [code](), [desktop-linux](), [hdmi](), [improvement](), [linus-torvalds](), [linux](), [linux-7-4](), [linux-benchmarking](), [linux-hardware-benchmarks](), [linux-hardware-reviews](), [linux-how-to](), [linux-performance](), [linux-server-benchmarks](), [merge](), [open-source-graphics](), [optimization](), [phoronix](), [phoronix-test-suite](), [release](), [ubuntu-benchmarks](), [ubuntu-hardware]() ### AI overview Linux 7.4-rc2 includes fixes and updates across several kernel areas: a FAT32 improvement that is especially notable with synchronous mounts, AMDGPU fixes for HDMI 2.2 FRL, adjustments to AMD PerfOpt for Radeon iGPU performance, a correction to BHI mitigation selection for some configurations, and fixes for long-standing memory-management bugs. Torvalds describes the diffstat as large but says automated Coccinelle updates account for much of its spread across files. He notes that, at least in BPF, fixes may now be arriving faster than new AI-related reports, while cautioning that other areas may not have reached that point. The release announcement asks for continued testing. ### Source excerpt Linus Torvalds just released the second weekly release candidate of Linux 7.4 with some notable bug fixes and other changes routed in past the merge window. It's another big one in the AI era... ## Linux 7.5 To Provide More AMD Ryzen AI NPU AIE4 Enablement DevFeed: [Linux 7.5 To Provide More AMD Ryzen AI NPU AIE4 Enablement]() Original publisher: [Read original article]() Author: Michael Larabel Published: 2026-11-08T12:22:24Z Content type: news Language: en Sources: [Phoronix]() Topics: [Linux Kernel](), [Linux]() Tags: [ai](), [amd](), [amd-ryzen](), [desktop-linux](), [drm](), [enablement](), [feature](), [kernel](), [linux](), [linux-benchmarking](), [linux-hardware-benchmarks](), [linux-hardware-reviews](), [linux-how-to](), [linux-performance](), [linux-server-benchmarks](), [misc](), [more](), [next](), [npu](), [open-source-graphics](), [over](), [patches](), [phoronix](), [phoronix-test-suite](), [provide](), [pull-request](), [request](), [ryzen](), [ryzen-ai](), [this](), [ubuntu-benchmarks](), [ubuntu-hardware]() ### AI overview A drm-misc-next pull request targeting Linux 7.5 adds Rockchip RK3568 support to the Rockchip DRM display driver and support for a range of additional panels. AMD's Ryzen AI NPU accelerator driver also gains support for firmware 6.0, including NPU3 classic devices, power-mode handling for AIE4 hardware, suspend and resume, clock, frequency and resource queries, and AIE4 command submission. The excerpt describes this as continued AIE4 enablement and says the hardware is presumed to be for upcoming Zen 6 client platforms; it does not establish that Linux 7.5 support is complete. ### Source excerpt Even before the Linux v7.4 merge window was over, there were already two pull requests of drm-misc-next material targeting for what will be Linux 7.5. This week already saw the third drm-misc-next pull request of more feature patches targeting this next kernel version... ## AMD PerfOpt Performance Boosting Code Tweaked For Linux 7.4-rc2 DevFeed: [AMD PerfOpt Performance Boosting Code Tweaked For Linux 7.4-rc2]() Original publisher: [Read original article]() Author: Michael Larabel Published: 2026-11-08T11:37:07Z Content type: news Language: en Sources: [Phoronix]() Topics: [Linux Kernel](), [Linux](), [radeon-gpu-profiler]() Tags: [ai](), [amd](), [bypass](), [desktop-linux](), [driver](), [gpu](), [identity](), [igpu](), [iommu](), [linux](), [linux-benchmarking](), [linux-hardware-benchmarks](), [linux-hardware-reviews](), [linux-how-to](), [linux-performance](), [linux-server-benchmarks](), [llm](), [memory](), [open-source-graphics](), [parameter](), [patch](), [performance](), [phoronix](), [phoronix-test-suite](), [stable](), [ubuntu-benchmarks](), [ubuntu-hardware]() ### AI overview AMD PerfOpt lets supported integrated GPUs bypass the IOMMU for direct system memory access, and is enabled by default for AMDGPU iGPUs. Linux 7.4-rc2 moves its control into IOMMU domain attachment: eligible GPUs receive PerfOpt in the default identity domain, while translated attachments keep normal device capability setup. The changes clear bypass before attaching a GPU to translated or blocked domains, including VFIO unmanaged domains; failures to clear bypass are propagated, but failure to enable the optional feature does not invalidate an otherwise completed identity attachment. Initialization clears inherited state, checks hardware support directly, and stops if the initial clear fails. Activation is tracked per IOMMU and restored on resume only if previously active. The amdgpu.iommu_perfopt parameter and related driver interfaces are removed. The text says Linux 7.4-rc2 was expected for testing that day and stable Linux 7.4 was anticipated around late December. ### Source excerpt Of the many exciting changes in Linux 7.4, one of the exciting out-of-the-box performance improvements is the new "PerfOpt" functionality for AMD SoCs with integrated Radeon graphics. AMD PerfOpt can deliver some nice iGPU performance improvements especially for AI/LLM workloads. With today's Linux 7.4-rc2 kernel release there are a few tweaks to the PerfOpt code in the IOMMU area... ## Yunsilicon Working To Upstream Their High Performance Linux Network Driver DevFeed: [Yunsilicon Working To Upstream Their High Performance Linux Network Driver]() Original publisher: [Read original article]() Author: Michael Larabel Published: 2026-11-08T11:27:33Z Content type: news Language: en Sources: [Phoronix]() Topics: [Linux Kernel](), [Linux](), [rdma]() Tags: [desktop-linux](), [driver](), [hardware](), [kernel](), [linux](), [linux-benchmarking](), [linux-hardware-benchmarks](), [linux-hardware-reviews](), [linux-how-to](), [linux-kernel](), [linux-performance](), [linux-server-benchmarks](), [mainline](), [network](), [networking](), [open-source-graphics](), [phoronix](), [phoronix-test-suite](), [ubuntu-benchmarks](), [ubuntu-hardware](), [upstream]() ### AI overview Yunsilicon submitted a three-driver series seeking mainline Linux support for a dual-function PCIe adapter (vendor 0x1f67) with Ethernet and RDMA. The shared xsc_pci core owns the PCI function and common queues, interrupts, registers, and resource pools, then publishes an auxiliary device for each function. The xsc_eth and xsc_ib drivers bind to that device, sharing the core's probe and resources. Ethernet support includes TX/RX paths using NAPI and page_pool, RSS, checksum offloads, and statistics; RDMA support registers an ib_device and provides verbs and data paths, with the netdev supplying port state and GID. The excerpt says the GPLv2 driver has been in development since 2021 and that patches appeared on LKML the previous month, followed by a more complete submission this week. It does not establish whether the series has been accepted into mainline. ### Source excerpt Yunsilicon is a Chinese semiconductor startup founded in 2021 that is working on producing high performance networking adapters and DPUs. Over the past month has been their first foray into posting patches to the Linux kernel mailing list and working to get their networking hardware supported by the mainline Linux kernel... ## GCC 17 Feature Development Ends Next Week DevFeed: [GCC 17 Feature Development Ends Next Week]() Original publisher: [Read original article]() Author: Michael Larabel Published: 2026-11-08T11:12:21Z Content type: news Language: en Sources: [Phoronix]() Topics: [gcc]() Tags: [17](), [ace](), [ai](), [ai-compute](), [all](), [amd](), [atomic](), [benchmarks](), [bug](), [c-plus-plus-29](), [changes](), [collection](), [compiler](), [compute](), [core](), [desktop-linux](), [development](), [feature](), [focus](), [gcc](), [linux-benchmarking](), [linux-hardware-benchmarks](), [linux-hardware-reviews](), [linux-how-to](), [linux-performance](), [linux-server-benchmarks](), [next](), [open-source-graphics](), [phoronix](), [phoronix-test-suite](), [ubuntu-benchmarks](), [ubuntu-hardware]() ### AI overview GCC 17 feature development is scheduled to end on 15 November, when the project plans to move from stage one to stage three and focus on bug fixes and new ports that do not affect other compiler areas.

A standby successor kernel monitors the running kernel; after a panic or hang, it fences the predecessor's CPUs, takes over and resets devices, restores network identity, can optionally save a kdump-compatible vmcore, and adds the remaining CPUs and memory. The excerpt says detection to a running successor takes about one second; important services such as Nginx can be kept in standby for recovery in as little as two seconds. Kmorph can also hand a healthy system to a successor running a newer kernel. It currently works on x86_64 and ARM64, with RISC-V support in progress, but depends on Multikernel code that is not in mainline Linux, limiting widespread adoption for now. ### Source excerpt Kmorph aims to provide reboot-less kernel crash recovery for Linux systems and can yield as little as ~2 second downtime for recovering the Nginx web server or other important services in the case of a kernel crash... ## KDE Plasma 6.9 Will Stop Leaking Memory When Right Clicking Files/Folders On Desktop DevFeed: [KDE Plasma 6.9 Will Stop Leaking Memory When Right Clicking Files/Folders On Desktop]() Original publisher: [Read original article]() Author: Michael Larabel Published: 2026-11-07T11:34:48Z Content type: news Language: en Sources: [Phoronix]() Topics: [memory handling]() Tags: [desktop](), [desktop-linux](), [files](), [kde](), [kde-plasma](), [linux-benchmarking](), [linux-hardware-benchmarks](), [linux-hardware-reviews](), [linux-how-to](), [linux-performance](), [linux-server-benchmarks](), [memory](), [open-source-graphics](), [phoronix](), [phoronix-test-suite](), [plasma](), [ubuntu-benchmarks](), [ubuntu-hardware]() ### AI overview KDE developers are preparing Plasma 6.9 with several usability changes: users will be able to reposition on-screen display pop-ups, and desktop widgets will be sized to avoid cutting off their content.

The developer says the stack has undergone many iterations and has been used daily on Windows 11; they describe it as stable and say binaries were shared with a few people. A further change involving DeviceProperty support and the USB4 Host and Device routers depends on this import, so USB 4 support is presented as future work, not as already available. ### Source excerpt After years of work, ReactOS as the "open-source Windows" operating system striving for Windows program and driver compatibility now has an initial USB 3.0 driver stack in place... ## A RISC-V Based TEE With AMD Zen 6 CPUs DevFeed: [A RISC-V Based TEE With AMD Zen 6 CPUs]() Original publisher: [Read original article]() Author: Michael Larabel Published: 2026-11-06T19:30:49Z Content type: news Language: en Sources: [Phoronix]() Topics: [RISC-V]() Tags: [amd](), [amd-ryzen](), [desktop-linux](), [linux-benchmarking](), [linux-hardware-benchmarks](), [linux-hardware-reviews](), [linux-how-to](), [linux-performance](), [linux-server-benchmarks](), [open-source-graphics](), [phoronix](), [phoronix-test-suite](), [risc-v](), [tee](), [ubuntu-benchmarks](), [ubuntu-hardware](), [zen-6]() ### AI overview A linux-firmware commit for AMD Family 1Ah M80h describes PMF Trusted Application firmware v4 running on a RISC-V-based TEE. The firmware adds a larger shared-memory layout and supports more policy conditions, including up to 20 custom BIOS inputs; PMF manages power, thermal, and system behavior. The article contrasts this with the historically ARM Cortex-A5 and TrustZone-based AMD Secure Processor, but says it is unclear whether the RISC-V implementation is new to Zen 6 or was also present in recent Zen 5 processors. ### Source excerpt An interesting technical detail I noticed today from the latest AMD Linux activity is that Zen 6 processors apparently are featuring a RISC-V based Trusted Execution Environment (TEE) where in the past it was an ARM-based core... ## Linux 7.4-rc2 Change Yields As Much As 162x Improvement For FAT32 DevFeed: [Linux 7.4-rc2 Change Yields As Much As 162x Improvement For FAT32]() Original publisher: [Read original article]() Author: Michael Larabel Published: 2026-11-06T16:21:38Z Content type: news Language: en Sources: [Phoronix]() Topics: [Linux Kernel](), [Linux]() Tags: [7-4](), [benchmarks](), [clusters](), [desktop-linux](), [fat](), [filesystem](), [improvements](), [linux](), [linux-benchmarking](), [linux-hardware-benchmarks](), [linux-hardware-reviews](), [linux-how-to](), [linux-performance](), [linux-server-benchmarks](), [open-source-graphics](), [performance](), [performance-optimization](), [phoronix](), [phoronix-test-suite](), [qemu](), [ubuntu-benchmarks](), [ubuntu-hardware]() ### AI overview A Linux 7.4-rc2 change speeds FAT32 file expansion by preallocating clusters in `fat_cont_expand()` instead of relying on generic code that makes many small allocations. A new `fat_preallocate()` helper is shared with `fat_fallocate(FALLOC_FL_KEEP_SIZE)`, and a FAT-specific expansion helper avoids rechecking the size after allocation. The largest reported gains are for FAT32 filesystems with small cluster sizes on synchronous mounts; QEMU benchmarks show particularly large improvements there. The supplied excerpt does not include the benchmark figures. ### Source excerpt In addition to a FAT32 optimization yielding as much as a 265x improvement that was merged for the Linux 7.4 cycle and separately another big FAT32 improvement expected for Linux 7.5, merged this week as part of the non-MM fixes for Linux 7.4-rc2 was another big FAT32 performance optimization... ## Arch Linux vs. CachyOS vs. Omarchy 4.5 Performance Benchmarks DevFeed: [Arch Linux vs. CachyOS vs. Omarchy 4.5 Performance Benchmarks]() Original publisher: [Read original article]() Author: Michael Larabel Published: 2026-11-06T14:55:52Z Content type: comparison Language: en Sources: [Phoronix]() Topics: [Linux Hardware Reviews](), [Arch Linux](), [Linux]() Tags: [amd](), [amd-ryzen](), [arch-linux](), [article](), [benchmarks](), [computer](), [desktop](), [desktop-linux](), [distributions](), [first-look](), [framework](), [gcc](), [graphics](), [install](), [kde-plasma](), [kernel](), [linux](), [linux-benchmarking](), [linux-hardware-benchmarks](), [linux-hardware-reviews](), [linux-how-to](), [linux-performance](), [linux-server-benchmarks](), [omarchy](), [open-source-graphics](), [performance](), [phoronix](), [phoronix-test-suite](), [ubuntu-benchmarks](), [ubuntu-hardware](), [upstream](), [vs]() ### AI overview The excerpt describes a three-way performance test on the same Framework Desktop with an AMD Ryzen AI Max+ 395, 64 GB RAM, Radeon 8060S graphics, and a 2 TB NVMe SSD. Arch Linux used a generic archinstall setup with KDE Plasma; CachyOS and Omarchy 4.5 used stock installs. At testing, CachyOS ran Linux 7.3, while Arch and Omarchy ran Linux 7.2; all used GCC 16.2. Omarchy defaulted to the performance profile, while Arch and CachyOS defaulted to balanced. CachyOS also included Zen 4+ optimized packages and other out-of-the-box tuning. The excerpt gives no benchmark results, so it does not establish which distribution performed best. ### Source excerpt With CachyOS recently having rolled out its Linux 7.3 based kernel and various other improvements plus with Omarchy 4.5 having been released this week, this article provides a look at how CachyOS and Omarchy are competing on the performance front relative to upstream Arch Linux. ## Linux x86 32-bit Patches Clean Old Kernel Code After Recently Removing Vintage CPUs DevFeed: [Linux x86 32-bit Patches Clean Old Kernel Code After Recently Removing Vintage CPUs]() Original publisher: [Read original article]() Author: Michael Larabel Published: 2026-11-06T14:11:31Z Content type: news Language: en Sources: [Phoronix]() Topics: [Linux Kernel](), [Linux](), [x86](), [patches]() Tags: [32-bit](), [amd](), [cache](), [can](), [code](), [compare](), [counter](), [cpu](), [cpus](), [dependencies](), [desktop-linux](), [developer](), [exchange](), [kernel](), [linux](), [linux-benchmarking](), [linux-hardware-benchmarks](), [linux-hardware-reviews](), [linux-how-to](), [linux-performance](), [linux-server-benchmarks](), [open-source-graphics](), [other](), [patches](), [phoronix](), [phoronix-test-suite](), [support](), [ubuntu-benchmarks](), [ubuntu-hardware](), [vintage](), [with](), [x86]() ### AI overview After older 32-bit CPUs were removed from Linux support, Arnd Bergmann proposed x86 32-bit cleanup patches. They remove lingering AMD Elan code and other obsolete dependencies, make Time Stamp Counter (TSC) and CX8 support unconditional, require at least 64-byte cache lines, and simplify instruction-set selection. The stated aim is to remove unnecessary code and bring 32-bit x86 code closer to x86_64; the excerpt describes a patch series, not whether it was merged. ### Source excerpt With the Linux kernek having phased out i486 CPU support and dropping old AMD Elan SoC code along with removing other obsolete and stagnate 32-bit x86 hardware support, some x86 32-bit clean-ups are proceeding along with being able to make the kernel depend unconditionally now on some features... ## FEX Awaits The Linux Kernel To Align With Windows & macOS On ARM Register Usage DevFeed: [FEX Awaits The Linux Kernel To Align With Windows & macOS On ARM Register Usage]() Original publisher: [Read original article]() Author: Michael Larabel Published: 2026-11-06T13:12:24Z Content type: news Language: en Sources: [Phoronix]() Topics: [Linux Kernel](), [WINE](), [macOS](), [Windows]() Tags: [abi](), [align](), [all](), [also](), [application](), [applications](), [arm](), [behavior](), [desktop-linux](), [games](), [improvements](), [jit](), [kernel](), [linux](), [linux-benchmarking](), [linux-hardware-benchmarks](), [linux-hardware-reviews](), [linux-how-to](), [linux-kernel](), [linux-performance](), [linux-server-benchmarks](), [macos](), [open-source-graphics](), [phoronix](), [phoronix-test-suite](), [running](), [ubuntu-benchmarks](), [ubuntu-hardware](), [windows](), [windows-on-arm](), [wine](), [with]() ### AI overview FEX is preparing to use TPIDRRO_EL0 for faster and more reliable emulation if the Linux kernel changes the register to report the current CPU core, matching Windows on ARM and macOS. Linux currently returns zero, so FEX uses a getcpu system call; under Wine, it cannot use Linux syscalls properly and has disabled RDPID/RDTSCP-related instructions. The excerpt says games are beginning to require these instructions, making register support relevant to both correctness and performance. An Igalia patch proposed reporting the running CPU in the register, but Will Deacon raised concern that this would prevent other future uses. FEX 2611 is being prepared for the change, while the Linux kernel's adoption remains uncertain; the release also includes continued JIT work. ### Source excerpt FEX 2611 is out for running Linux (and Wine) x86/x86_64 games/applications on AArch64 Linux. FEX 2611 brings JIT improvements while also waiting for the Linux kernel to align with the AArch64 specification and Windows on ARM and macOS Apple Silicon behavior around a particular register's usage... ## Linux Developers Look To Drop RT\_GROUP\_SCHED As It's "Broken Beyond Repair" DevFeed: [Linux Developers Look To Drop RT\_GROUP\_SCHED As It's "Broken Beyond Repair"]() Original publisher: [Read original article]() Author: Michael Larabel Published: 2026-11-06T11:09:14Z Content type: news Language: en Sources: [Phoronix]() Topics: [Linux Kernel](), [cgroups](), [Linux](), [scheduling](), [deprecated]() Tags: [cgroups](), [desktop-linux](), [developers](), [kernel](), [linux](), [linux-benchmarking](), [linux-hardware-benchmarks](), [linux-hardware-reviews](), [linux-how-to](), [linux-performance](), [linux-server-benchmarks](), [open-source-graphics](), [phoronix](), [phoronix-test-suite](), [real-time](), [scheduling](), [ubuntu-benchmarks](), [ubuntu-hardware]() ### AI overview Linux kernel developers have proposed removing RT_GROUP_SCHED, a cgroups v1-era feature that the patch author calls "broken beyond repair." The excerpt says cgroup v2 cannot assign the runtime needed for SCHED_FIFO or SCHED_RR tasks, while the root group's runtime constrains reducing the global real-time runtime setting. SCHED_DEADLINE tasks can be scheduled, but admission control is stuck unless disabled through the same sysctl. The author says major distributions already disable the feature and points to the DL fair server's RT throttling and ongoing work on hierarchical constant bandwidth servers as alternatives. Some users may still depend on the code, and kernel developers have raised whether deprecation should precede removal; the excerpt says the patch is likely to advance, not that removal is complete. ### Source excerpt Linux kernel developers are looking at dropping the RT_GROUP_SCHED feature that is used for group scheduling of real-time tasks using cgroups...
