Beyond EH Frame and Frame Pointers: The Technical Underpinnings of #SFrame

https://blogs.oracle.com/linux/post/beyond-eh-frame-frame-pointers-the-technical-underpinnings-of-sframe

""[…] SFrame, a new, lightweight, and highly efficient stack trace format designed to address the challenges and limitations of existing solutions. SFrame aims to provide accurate stack traces with minimal overhead, making it ideal for performance-critical scenarios like live tracing, profiling, and online debugging. Its design is guided by three core principles:

Minimal Data: SFrame captures only the essential stack frame details, drastically reducing overhead.
Ease of Use: SFrame is designed for straightforward parsing and generation by tools, simplifying integration.
Online Operations: SFrame is perfectly suited for real-time debugging and analysis, enabling responsive insights.

SFrame is currently expanding its adoption across various platforms, with Indu Bhagat actively working with the wider GNU/Linux community on its next version - SFrame version 3. […]""

Dissecting the Apple M1 GPU, the end

Alyssa Anne Rosenzweig writes: ""In 2020, #Apple released the M1 with a custom GPU. We got to work reverse-engineering the hardware and porting Linux. Today, you can run Linux on a range of M1 and M2 Macs, with almost all hardware working: wireless, audio, and full graphics acceleration.

Our story begins […]

…Now what?

Ship a great driver? Check.

Conformant OpenGL 4.6, OpenGL ES 3.2, and OpenCL 3.0? Check.

Conformant Vulkan 1.4? Check.

Proton gaming? Check.

That’s a wrap.

We’ve succeeded beyond my dreams. The challenges I chased, I have tackled. The drivers are fully upstream in Mesa. Performance isn’t too bad. With the Vulkan on Apple myth busted, conformant Vulkan is now coming to macOS via LunarG’s KosmicKrisp project building on my work.

Satisfied, I am now stepping away from the Apple ecosystem. My friends in the #Asahi #Linux orbit will carry the torch from here. As for me?

Onto the next challenge (https://www.intel.com/content/www/us/en/developer/articles/technical/introduction-to-the-xe-hpg-architecture.html)!""
