Linux 7.3 to Allow Tuning AMD P-State Dynamic EPP with per CPU Core Granularity

5 hours ago

Linux 7.3 kernel allows per-CPU core granularity for AMD P-State Dynamic EPP instead of a global switch.
Dynamic EPP is an opt-in feature that lets the kernel autonomously change the Energy Performance Preference (EPP) operating mode.
The global 'amd_dynamic_epp' module parameter and 'dynamic_epp' sysfs nodes are being removed.
Per-CPU control is achieved via the 'energy_performance_preference' mode set to 'dynamic' when using the powersave governor.
A related patch adjusts the min_limit_freq value based on bios_min_perf for users who manually tune settings.
The per-CPU toggle provides more granular control and fits naturally into the intended design.

WinPE provides a lightweight, RAM-based environment ideal for Windows driver testing and fuzzing due to minimal resource overhead and lack of unnecessary graphical components.
Key boot optimizations include BCD settings like 'ignoreallfailures' and 'recoveryenabled no' to enable fast, idempotent CI/CD pipelines and avoid recovery loops.
For unsigned driver testing, BCD settings such as 'testsigning yes' and 'hypervisorlaunchtype off' disable security features like VBS/HVCI, allowing kernel manipulation.

DMS 1.5 'The Wolverine' introduces Frame Mode, enabling connected shell surfaces for a unified interface.
Native integration of DankCalendar provides a single agenda for multiple accounts with event management and offline cache.
Enhanced greeter features include a settings GUI, multi-user management, per-user theme sync, and improved authentication support.

OCaml 5.5.0 introduces module-dependent functions, allowing modules as function arguments for lightweight functors.
The compiler is now relocatable, enabling switches to be cloned without recompilation for faster setup.
Higher-rank polymorphic functions can be defined directly using explicit type annotations in function arguments.

Package management functionality moved from compiler to build system, improving safety and allowing easier patching.
SPIR-V backend updated with new @SpirvType builtin, execution mode handling via calling convention, and multi-threaded codegen.
@bitCast semantics redefined to use logical bit layout, making operations endian-agnostic and more consistent.

Package management functionality moved from compiler to build system for flexibility and safety improvements.
SPIR-V backend progress includes new builtins, execution modes, multi-threaded codegen, and object file linking.
Redefined @bitCast semantics to use logical bit layout, improving cross-platform consistency.
