Welcome to the Avermedia-GC573-Linux Discussions!

This repository thrives on collective reverse engineering, testing, and kernel-level development. Thanks to recent milestones in Phase 4, the driver pipeline is fully stable, and the DMA system is actively triggering 60Hz frame completion interrupts. We are opening this space for deeper technical deep dives, diagnostic logs, and architectural collaboration.
Scope of the Discussions

Logs and Dmesg Analysis: Share your diagnostic outputs here when analyzing the "Green Screen of Death" or cache synchronization issues, rather than opening formal tracker issues for temporary experimental states.

Hardware and Architecture Modding: Discuss kernel parameters, Passthrough IOMMU behavior, specific compiler environments (such as Clang/LLVM), and memory barriers.

Planning Next Milestones: Help coordinate upcoming tasks like Phase 4b (validating active pixel data payload over userspace) and the long-term goal of waking up the ALSA audio DMA architecture.

Current Roadmap Context

We have eliminated the I2C-driven deadlocks from the streaming execution path. The implementation is completely sterile (MMIO/FPGA-only), allowing the proprietary blob to negotiate 4K HDMI source downscaling autonomously via native hardware pipelines. Our next immediate hurdle is ensuring physical memory pages refresh accurately before handing off buffers to userspace.

Please maintain professional and evidence-based exchange. When posting kernel logs, register dumps, or configuration matrices, enclose them within proper backtick code blocks (```).

Thank you to everyone dedicating time and test benches to mapping this hardware under open-source kernels. Let's solve the remaining memory mapping hurdles.
